Collective and state farms have been replaced by precarious smallholder agriculture suffering from a decline in financial inputs and the deterioration of infrastructure. At the same time, dynamic transformations of border permeability (and trans-border reconnections) between Kazakhstan and China have challenged the until relatively recent widespread Soviet rhetoric on Western China (or rather Xinjiang) as an underdeveloped space across the border. This article is based on several months of fieldwork between 2019 and 2021 in Panfilov District, located at major cross-border road and railway intersections and hosting important infrastructural objects, such as a dry port, a major railway transhipment hub, and a trans-border special economic zone. The article explores how the border situation (and the border's changing permeability for people, commodities, and ideas since the early 1990s) as well as the implementation of new trans-border infrastructures eventually shaped local discourses and practices in the socio-economic development of south-east Kazakhstan's agricultural sector. It is scrutinized herein how various forms of trans-border socio-economic interactions (although heavily regulated) and China's (agri-) economic policy in Xinjiang started to affect farmers' ambitions and practices across the border.}, language = {en} } @article{WenigReppeHorbeltetal.2023, author = {Wenig, Charlett and Reppe, Friedrich and Horbelt, Nils and Spener, Jaromir and Berendt, Ferr{\´e}ol and Cremer, Tobias and Frey, Marion and Burgert, Ingo and Eder, Michaela}, title = {Adhesives free bark panels: An alternative application for a waste material}, series = {PloS one}, volume = {18}, journal = {PloS one}, number = {1}, publisher = {Public Library of Science (PLoS)}, doi = {10.1371/journal.pone.0280721}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6104}, year = {2023}, abstract = {The proportion of bark in tree trunks is in the range of ~ 10-20\%.

Recently, efforts towards the use of bark have been made, e.g. as a raw material to harvest different chemical compounds or as an additive for wood particle boards. Our motivation for this work was to keep the bark in an almost natural state and explore alternative processes and applications for use. The traditional method of de-barking tree trunks by peeling was used to harvest large bark pieces. Two pieces of peeled bark were placed crosswise, with the rhytidom side (outer bark) facing each other. After different conditioning steps, bark pieces were hot pressed to panels without adding adhesives. These experiments on bark samples of different Central European tree species suggest that production of panels with species dependent properties is possible and feasible. This is a step towards producing sustainable panels by using a natural waste material, while retaining its beneficial structure and its natural chemical composition.}, language = {en} } @misc{BolteRockWolff2021, author = {Bolte, Andreas and Rock, Joachim and Wolff, Barbara}, title = {Setting aside forests or harvesting them for bioenergy: Short-term benefits for climate protection are still unknown}, series = {GCB Bioenergy}, volume = {13}, journal = {GCB Bioenergy}, number = {3}, publisher = {Wiley}, issn = {1757-1707}, doi = {10.1111/gcbb.12769}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6081}, pages = {364 -- 366}, year = {2021}, language = {en} } @article{PaulKuhnSteinhoffKnoppetal.2020, author = {Paul, Carsten and Kuhn, Kristin and Steinhoff-Knopp, Bastian and Weißhuhn, Peter and Helming, Katharina}, title = {Towards a standardization of soil-related ecosystem service assessments}, series = {European Journal of Soil Science}, volume = {72}, journal = {European Journal of Soil Science}, number = {4}, publisher = {Wiley}, issn = {1365-2389}, doi = {10.1111/ejss.13022}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5801}, pages = {1543 -- 1558}, year = {2020}, abstract = {The concept of ecosystem services (ES) creates understanding of the value of ecosystems for human well-being. With regard to soils, it provides a framework for assessments of soil contributions and soil management impacts. However, a lack of standardization impedes comparisons between assessment studies and the building of synthesis information. The Common International Classification of Ecosystem Services (CICES) is an important step forward, although its application to soils is not without difficulty. CICES version 5.1 defines 83 ES classes, of which only some are relevant for soils. We compiled two subsets of CICES classes: one set of soil-related ES comprising 29 services defined as directly and quantifiably controlled by soils and their properties, processes and functions, and another set of 40 ES defined as being affected by agricultural soil management. Additionally, we conducted a systematic literature review, searching for published lists of soil-related ES that claim completeness. We identified 11 relevant lists. Of all CICES classes, 12 were included in more than 75\% of the lists, whereas another 36 classes were included in 25-75\% of them. Regarding the suitability of the CICES classification for addressing ES in the context of soils and their agricultural management, we identified constraints, such as overlaps, gaps, and highly specific or very broad class definitions. Close cooperation between the soil research and ES communities could ensure better consideration of soils in future CICES updates. A shortlist of 25 service classes affected by agricultural soil management facilitates a standardized approach and may function as checklists in impact assessments.}, language = {en} } @article{BielyvonMuenchhausenvanPassel2022, author = {Biely, Katharina and von M{\"u}nchhausen, Susanne and van Passel, Steven}, title = {Vertical integration as a strategy to increase value absorption by primary producers: The Belgian sugar beet and the German rapeseed case}, series = {AIMS Agriculture and Food}, volume = {7}, journal = {AIMS Agriculture and Food}, number = {3}, publisher = {AIMS Press}, issn = {2471-2086}, doi = {10.3934/agrfood.2022041}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5610}, pages = {659 -- 682}, year = {2022}, abstract = {Vertical integration is a means of increasing market power. For some agricultural products, it is easier for farmers to exert control over their product beyond the farm gate, but for others it is more difficult. Cases in the latter category have two main characteristics. First, the farmer cannot sell the respective product to final consumers without processing. Second, processing is capital-intensive. Consequently, farmers have limited sales channels, and vertical integration of the supply chain is complex and challenging. It implies cooperation among farmers to process the raw material at a profitable scale and to finance the installation of processing facilities. Thus, for these product categories, farmers are prone to market power issues, since they depend on private businesses that have the financial means to install processing facilities and the logistical capacities to organize the collection of large amounts of raw material. This paper aims to identify and analyze the role of supply chain integration for farmers who are already cooperating horizontally. Two case studies serve as the basis for the analysis: sugar beet in Flanders, Belgium, and oilseed rape in Hessen, Germany. The analysis is based on a qualitative research approach combining interviews, focus groups, and workshops with farmers and processors. While for sugar beet, the effects of market power are emerging only now with the termination of the quota system, farmers growing oilseed rape have been experiencing these problems since the 1990s. Our analysis concludes that most strategies to maintain or improve farm income have been exhausted. Even various forms of vertical integration supported by European policies do not necessarily work as a successful strategy.}, language = {en} } @article{ZellerGoettert2021, author = {Zeller, Ulrich and G{\"o}ttert, Thomas}, title = {Humans, megafauna and landscape structure - Rock engravings from Namibia encourage a comparative approach to central Europe and southern Africa}, series = {Vertebrate Zoology}, volume = {71}, journal = {Vertebrate Zoology}, issn = {1864-5755}, doi = {10.3897/vz.71.e72811}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5538}, pages = {631 -- 643}, year = {2021}, abstract = {This paper deals with reflections that arose after observing prehistoric rock engravings at different locations in Namibia. These observations stimulated comparative considerations with focus on southern Africa and central Europe. Similar to the Aurignacian rock art of European origin, the most common motifs in the Namibian rock engravings are large animals. While in Europe, the species that served as a blueprint for the illustration of Aurignacian rock art have mostly disappeared, the megafauna illustrated on the rock engravings in Namibia can still be found in the immediate vicinity of the rock art. Against this background, we discuss and further develop a comparative regional approach. We reconstruct and evaluate the suitability of African savannas and still-existing megafauna communities as an appropriate reference-frame for natural European grassland systems and extinct associated warm-adapted megafauna (Eemian Interglacial megafauna). Special attention is laid on the unique situation in Africa in the light of a global extinction wave of megafauna following increasing human activity in the Late Quaternary. This leads us to discuss the use of domesticated ungulates as surrogate taxa to fulfill ecosystem functions in Europe as part of concepts termed "rewilding" or "naturalistic grazing". After critically examining these concepts, we conclude that using domesticated forms as representatives of extinct or locally disappeared species in Europe has its justification to some extent. If, however, the naturally occurring megaherbivore community still exists (Africa), these naturally occurring species should be given priority due to their organismic abilities and limitations adapted to the harsh conditions in their specific environment. Finally, we discuss the application of (transboundary) protected areas as effective instruments to mitigate human-wildlife conflicts. A holistic approach, including nature conservation and preservation of cultural achievements (domesticated forms, grazing systems), appears promising for the effective protection of the natural African savanna ecosystems with their unique fauna elements, as illustrated in rock engravings that inspired us to write this paper.}, language = {en} } @inproceedings{SchroederGuerickeKoerner2021, author = {Schr{\"o}der, Jens and Guericke, Martin and K{\"o}rner, Michael}, title = {Fingerprints of biotic agents in tree-ring and NDVI time series of forest stands}, series = {TRACE - Tree Rings in Archeology, Climatology and Ecology - Virtual Conference 2021}, booktitle = {TRACE - Tree Rings in Archeology, Climatology and Ecology - Virtual Conference 2021}, doi = {10.13140/RG.2.2.17808.33286}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5559}, pages = {1}, year = {2021}, language = {en} } @article{GrohDiamantopoulosDuanetal.2022, author = {Groh, Jannis and Diamantopoulos, Efstathios and Duan, Xiaohong and Ewert, Frank and Heinlein, Florian and Herbst, Michael and Holbak, Maja and Kamali, Bahareh and Kersebaum, Kurt-Christian and Kuhnert, Matthias and Nendel, Claas and Priesack, Eckart and Steidl, J{\"o}rg and Sommer, Michael and P{\"u}tz, Thomas and Vanderborght, Jan and Vereecken, Harry and Wallor, Evelyn and Weber, Tobias K.

Still challenging is the model performance when considering complex interrelations between soil and crop dynamics under a changing climate. The objective of this study was to test the agronomic crop and environmental flux-related performance of a set of crop models. The aim was to predict weighing lysimeter-based crop (i.e., agronomic) and water-related flux or state data (i.e., environmental) obtained for the same soil monoliths that were taken from their original environment and translocated to regions with different climatic conditions, after model calibration at the original site. Eleven models were deployed in the study. The lysimeter data (2014-2018) were from the Dedelow (Dd), Bad Lauchst{\"a}dt (BL), and Selhausen (Se) sites of the TERENO (TERrestrial ENvironmental Observatories) SOILCan network. Soil monoliths from Dd were transferred to the drier and warmer BL site and the wetter and warmer Se site, which allowed a comparison of similar soil and crop under varying climatic conditions. The model parameters were calibrated using an identical set of crop- and soil-related data from Dd. Environmental fluxes and crop growth of Dd soil were predicted for conditions at BL and Se sites using the calibrated models. The comparison of predicted and measured data of Dd lysimeters at BL and Se revealed differences among models. At site BL, the crop models predicted agronomic and environmental components similarly well. Model performance values indicate that the environmental components at site Se were better predicted than agronomic ones. The multi-model mean was for most observations the better predictor compared with those of individual models. For Se site conditions, crop models failed to predict site-specific crop development indicating that climatic conditions (i.e., heat stress) were outside the range of variation in the data sets considered for model calibration. For improving predictive ability of crop models (i.e., productivity and fluxes), more attention should be paid to soil-related data (i.e., water fluxes and system states) when simulating soil-crop-climate interrelations in changing climatic conditions.}, language = {en} } @article{RaabSpies2023, author = {Raab, Christoph and Spies, Michael}, title = {Characterising cropland fragmentation in post-Soviet Central Asia, using Landsat remote-sensing time series data}, series = {Applied Geography}, journal = {Applied Geography}, number = {156}, publisher = {Elsevier}, issn = {0143-6228}, doi = {10.1016/j.apgeog.2023.102968}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5362}, year = {2023}, abstract = {Following the dissolution of the Soviet Union, agricultural reforms in Central Asia often translated into the fragmentation of large fields into smaller shares.

To investigate forestry innovations as systems, the analysis focuses on biophysical, social and technical factors influencing innovation development. The results of our exploratory quantitative analysis show that most innovation activities identified are largely oriented towards biomass production. Accordingly, most forest owners implement efficiency-driven optimisation strategies for forest management and technological improvement for provisioning service supply, to generate income. In contrast, the provision of regulating and cultural services is not yet a prominent part of forestry innovation activities.Reasons are rooted in a market-oriented economic rationale focusing on timber production, a lack of financial resources to compensate for other FES provisions or institutions to provide backup and security to forest owners and managers for engaging in innovation development. Given that the provision of a wide range of FES is a politically well-established objective for forest management in Europe, a strategy is needed that helps to align actors and sectors for supporting and co-financing related forest management approaches and business models.

European forest owners and policy makers alike are looking for governance innovations that generate economic opportunity while ensuring the future provision of FES. This systematic literature review aims to consolidate existing academic empirical research on local or regional level governance innovations in Europe concerned with generating forest-based revenue through FES provision. Thus, it complements conceptual literature dealing with challenges and opportunities of financing the provision of FES. When conducting the review we followed the process guidelines developed by 'Collaboration for Environmental Evidence' (Collaboration for Environmental Evidence, 2018). Out of a total of 3962 scanned papers, 23 papers containing 48 case studies were identified and analyzed in detail, to address the following guiding questions: (1) What types of FES related (governance) innovations for forest-based revenue generation exist and which FES do they address? (2) What are the motivations driving innovation development? (3) What are the implications for forest management? We found four types of governance innovations: forest product and organizational innovations which largely relate to provisioning FES; service innovations, which generally relate to cultural FES; and financial incentive systems or payment schemes targeting mostly regulating services. We identify potential synergies between two high-priority EU policy objectives: rural economic development and securing future FES provision. Currently, governance innovations' forest management implications and associated impact on (future) FES provision are rarely addressed in this literature.

We identified and prioritized fifteen major challenges hindering the balanced provision of multiple FES and identified a series of potential solutions to tackle each of them. The most prominent challenges referred to the increased frequency and impacts of extreme weather events and the normative mindset regarding forest management. The respective solutions pointed to the promotion of forest resilience via climate-smart forestry and mainstreaming FES-oriented management through a threefold strategy focusing on education, awareness raising, and networking. In a subsequent survey, most solutions were assessed as highly effective, transferable, monitorable, and with potential for being economically efficient. The implementation of the solutions could have synergistic effects when applying the notion of leverage points. Seven emerging pathways towards the sustainable supply of FES have been identified. These pathways build on each other and are organized based on their potential for transformation: (1) shifting forest management paradigms towards pluralistic ecosystem valuation; (2) using integrated landscape approaches; (3) increasing forest resilience; (4) coordinating actions between forest-related actors; (5) increasing participation in forest planning and management; (6) continuous, open, and transparent knowledge integration; and (7) using incentive-based instruments to support regulating and cultural FES.

Drainage-based peatland use has also negative impacts on water quality, drinking water provision and biodiversity. Consequently, key EU environmental policy objectives include the rewetting of all drained peatlands as an essential nature-based solution. Rewetting of peatlands can be combined with site-adapted land use, so-called paludiculture. Paludiculture produces biomass from wet and rewetted peatlands under conditions that maintain the peat body, facilitate peat accumulation and can provide many of the ecosystem services associated with natural, undrained peatlands. The biomass can be used for a wide range of traditional and innovative food, feed, fibre and fuel products. Based on examples in Germany, we have analysed emerging paludiculture options for temperate Europe with respect to greenhouse gas fluxes, biodiversity and indicative business economics. Best estimates of site emission factors vary between 0 and 8 t CO2eq ha-1 y-1. Suitability maps for four peatland-rich federal states (76\% of total German peatland area) indicate that most of the drained, agriculturally used peatland area could be used for paludiculture, about one-third of the fen area for any paludiculture type. Fen-specific biodiversity benefits from rewetting and paludiculture, if compared to the drained state. Under favourable conditions, paludiculture can be economically viable, but costs and revenues vary considerably. Key recommendations for large-scale implementation are providing planning security by paludiculture spatial planning, establishing best practice sites and strengthening research into crops, water tables and management options.}, language = {en} } @article{WeissLinde2022, author = {Weiss, Fabio and Linde, Andreas}, title = {How to estimate carabid biomass?—an evaluation of size-weight models for ground beetles (Coleoptera: Carabidae) and perspectives for further improvement}, series = {Journal of Insect Conservation}, volume = {26}, journal = {Journal of Insect Conservation}, publisher = {Springer Nature}, issn = {1366-638X}, doi = {10.1007/s10841-022-00391-6}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-4983}, pages = {537 -- 548}, year = {2022}, abstract = {Biomass is an important metric for monitoring carabid populations and serves as an ecological indicator. Models that predict carabid weight based on body size represent a simple and straightforward method to estimate biomass and are therefore commonly used.

It is designed as a combination of poplar shelterbelts and orchards, irrigated by river water from the Aksu River, the main tributary of the Tarim River. Prevalent literature describes it as an afforestation project for combatting desertification with manifold positive effects for the economic, social, and environmental dimension of sustainable development.

Methods comprise evapotranspiration calculations, interviews, a socioeconomic household survey, stakeholder dialogues, and literature research. Results affirm its economic sustainability, but see a mixed record for the social sphere. From the nature conservation point of view, it has to be classified as unsustainable because its high irrigation water consumption results in the downstream desiccation and desertification of natural riparian forests along the Tarim River, causing a forest loss in the downstream area twice the size of the forest gain in the upstream area. There is a trade-off between artificial shelterbelt plantations for urban ecosystem services on the one hand side, and natural riparian forests and their biodiversity on the other hand side.

Developing multifunctional forests requires understanding of the dynamic roles of traditions and cultural legacies in social-ecological systems at multiple levels and scales. Implementing policies about multifunctional forests requires a landscape and social-ecological perspective, and recognition of both spatial and temporal features at multiple scales. This study explores the dissemination of even-aged silviculture in central, eastern and northern Europe, and the consequences of choosing different vantage points in social-ecological systems for mapping of barriers, and to identify levers, towards multifunctional forest landscapes. Using a narrative approach, we first summarise the development of even-aged silviculture in four European regions. Next, we focus on Sweden as a keen adopter of even-aged silviculture, and identify levers at three groups of vantage points. They were (1) biosphere with biodiversity as short-hand for composition, structure and function of ecosystems, which support human well-being at multiple scales; (2) society in terms of different levels of stakeholder interactions from local to global, and (3) economy represented by value chain hierarchies and currencies. The emergence of even-aged silviculture >200 years ago formed an expanding frontier from central to northern Europe. Sustained yield wood production and biodiversity conservation encompass different portfolios of ecosystem aspects and spatio-temporal scales. Ignorance and lack of knowledge about these differences enforce their mutual rivalry. An exploratory review of six groups of stakeholders at multiple levels in the traditional industrial forest value chain highlights inequalities in terms of distribution of income and power across different levels of governance. This effectively marginalises other than powerful industrial actors. The distribution of financial results along the value chain is dynamic in space and time, and not all benefits of forest ecosystems can be measured using monetary valuation. There are also other currencies and incentives. A discussion of cultural trajectories in central and eastern European, Russian and Swedish forest management illustrates that forest history patterns repeat themselves. Longitudinal case studies of countries and regions can help foster holistic multi-dimensional and multi-level systems thinking. Application of deep levers of change is likely to require external drivers. A key challenge is to handle the manufacturing of doubt and decay of truth, i.e., the appearance of alternative facts, and the diminishing role of evidence and systems analyses in political and civic discourses.

These values, which safeguard ecosystem services in protected areas, are treated as models for the sustainable preservation and use of resources. While there is much research on the effectiveness of protected areas in a variety of disciplines, the question is whether there is a common framework that uses remote sensing methods. We conducted a qualitative and a quantitative analysis of 44 peer-reviewed scientific papers utilizing remote sensing data in order to examine the effectiveness of protected areas. Very few studies to date have a wide or even a global geographical focus; instead, most quantify the effectiveness of protected areas by focusing on local-scale case studies and single indicators such as forest cover change. Methods that help integrate spatial selection approaches, to compare a protected area's characteristics with its surroundings, are increasingly being used. Based on this review, we argue for a multi-indicator-based framework on protected area effectiveness, including the development of a consistent set of socio-ecological indicators for a global analysis. In turn, this will allow for globally applicable use, including a concrete evaluation that considers the diversity of regional parameters, biome-specific variables, and political frameworks.

Areas with no roads or little traffic ("roadless and low-traffic areas") represent relatively undisturbed natural habitats and functioning ecosystems. They provide many benefits for biodiversity and human societies (e.g., landscape connectivity, barrier against pests and invasions, ecosystem services). Roadless and low-traffic areas, with a lower level of anthropogenic disturbances, are of special relevance in Europe because of their rarity and, in the context of climate change, because of their contribution to higher resilience and buffering capacity within landscape ecosystems. An analysis of European legal instruments illustrates that, although most laws aimed at protecting targets which are inherent to fragmentation, like connectivity, ecosystem processes or integrity, roadless areas are widely neglected as a legal target. A case study in Germany underlines this finding. Although the Natura 2000 network covers a significant proportion of the country (16\%), Natura 2000 sites are highly fragmented and most low-traffic areas (75\%) lie unprotected outside this network. This proportion is even higher for the old Federal States (western Germany), where only 20\% of the low-traffic areas are protected. We propose that the few remaining roadless and low-traffic areas in Europe should be an important focus of conservation efforts; they should be urgently inventoried, included more explicitly in the law and accounted for in transport and urban planning.

Using farm household-level data of 400 rainfed farmers collected through a well-designed and field-tested questionnaire, this study examines the association between various adaptation stages (climate risk perceptions, adaptation planning, and implementation of adaptation) and their determinants using a multivariate probit (MVP) model. The findings indicate that farmers' perceptions of climatic changes are in line with historical climatic data. Climate risk management (CRM) trainings and digital agriculture extension and communication (DAEC) services (indicators of formal institutional arrangements) show a highly significant impact on all adaptation stages. Input market distance, farmer cooperative meetings (an indicator of informal institutional arrangement), off-farm income, education, and number of male family members are among the other key determinants. A highly significant association between various adaptation stages indicates that accurate climate risk perceptions lead to planning and implementation of adaptations. When risk perceptions are underestimated or lacking, then adaptations do not occur. The results further indicate that the timely availability of reliable information on advanced agricultural inputs, weather parameters, crop farming advisory services, and market information could help rainfed farmers devise sound adaptations to minimize risks associated with climate change.

Additionally, the accuracy and precision of using PLS and the suggested method when measuring roundwood volume was examined compared to measurements made using a xylometer and estimations obtained from applying the formulae of Huber, Smalian and Newton. For this purpose, several parameters were measured in 50 logs of Norway spruce with an average length of 2.53 m and a mean diameter of 19.97 cm. Afterwards, the volume of these 50 logs was measured with a xylometer. The results of these measurements served as reference values. The same 50 logs were subsequently scanned with the PLS. The scans were converted into point clouds and were analyzed in Cloud Compare to estimate the volume of the scanned logs. Next, the root mean square error (RMSE) and the mean bias error (MBE) as well as their relative values were calculated for the volumes determined in Cloud Compare and estimated with the above mentioned formulae. The calculated RMSE (and relative RMSE) determined a deviation of the logs' volumes estimated in Cloud Compare from the xylometric volumes of 2.88 dm3 (3.54\%) whereas the deviations of the log's volumes calculated applying the formulae of Huber, Smalian and Newton from the xylometric volumes were respectively 9.63 dm3 (11.83\%), 10.33 dm3 (12.69\%) and 4.69 dm3 (5.76\%). The calculated MBE (and relative MBE) showed that the estimated volumes in Cloud Compare and those using the formulae were overestimated, with the lowest overestimation of 0.10 dm3 (0.12\%) in Cloud Compare and the highest, 5.50 dm3 (6.75\%), using the Smalian formula. Therefore, it can be stated that results of suggested methodical processing line came closest to the logs' volumes obtained with the xylometer, i.e., they were more accurate and precise compared to the conventionally formulae for log's volume estimation.

In particular, a better mechanistic understanding of the range of pathways through which biodiversity can influence human health is needed. These pathways relate to both psychological and social processes as well as biophysical processes. Building on evidence from across the natural, social and health sciences, we present a conceptual framework organizing the pathways linking biodiversity to human health. Four domains of pathways—both beneficial as well as harmful—link biodiversity with human health: (i) reducing harm (e.g. provision of medicines, decreasing exposure to air and noise pollution); (ii) restoring capacities (e.g. attention restoration, stress reduction); (iii) building capacities (e.g. promoting physical activity, transcendent experiences); and (iv) causing harm (e.g. dangerous wildlife, zoonotic diseases, allergens). We discuss how to test components of the biodiversity-health framework with available analytical approaches and existing datasets. In a world with accelerating declines in biodiversity, profound land-use change, and an increase in non-communicable and zoonotic diseases globally, greater understanding of these pathways can reinforce biodiversity conservation as a strategy for the promotion of health for both people and nature.

Also, results demonstrated that with DBT greater than 20 mm, the percentage of Vbark exceeded 20\%. Finally, different linear regression models were recommended to predict Vbark and Mbark based on the other variables.

In this paper, we investigate and highlight the potential and limitations of the economic valuation of soil-based ecosystem services to inform sustainable soil management and policy. We formulate a definition of soil-based ecosystem services as basis for conducting a review of existing soil valuation studies with a focus on the inclusion of ecosystem services and the choice of valuation methods. We find that, so far, the economic valuation of soil-based ecosystem services has covered only a small number of such services and most studies have employed cost-based methods rather than state-of-the-art preference-based valuation methods, even though the latter would better acknowledge the public good character of soil related services. Therefore, the relevance of existing valuation studies for political processes is low. Broadening the spectrum of analyzed ecosystem services as well as using preference-based methods would likely increase the informational quality and policy relevance of valuation results. We point out options for improvement based on recent advances in economic valuation theory and practice.

In dairy sheep the relationship between milk performance and infection with gastrointestinal nematodes (GIN) is not well known. The aim of this study was to investigate the relationship between milk yield and GIN infection in dairy sheep and based on this, to evaluate milk performance data as a potential TST indicator. Overall 1159 Lacaune ewes of 15 dairy sheep farms in Switzerland were included in the study. The ewes were phenotyped once between August and December 2019, when they were at least 70 days in milk (DIM). Individual faecal samples were taken from every ewe to determine the nematode egg concentration per gram faeces (EPG). In addition, the clinical parameters FAMACHA score and packed cell volume (PCV) were measured. Linear mixed models were used to analyse the effects of the collected parameters on EPG. EPG increased significantly with increasing test day milk yields (P = 0.002), indicating high yielding ewes to be less resistant to GIN infections than low yielding ewes. The effect was most pronounced in earlier lactation but remained within a moderate range. Overall, our results indicated the potential of using milk yield data of rather early lactation as TST indicator in dairy sheep.

The effects of extreme droughts on trees are difficult to disentangle given the inherent complexity of drought events (frequency, severity, duration, and timing during the growing season). Besides, drought effects might be modulated by trees' phenotypic variability, which is, in turn, affected by long-term local selective pressures and management legacies. Here we investigated the magnitude and the temporal changes of tree-level resilience (i.e., resistance, recovery, and resilience) to extreme droughts. Moreover, we assessed the tree-, site-, and drought-related factors and their interactions driving the tree-level resilience to extreme droughts. We used a tree-ring network of the widely distributed Scots pine (Pinus sylvestris) along a 2,800 km latitudinal gradient from southern Spain to northern Germany. We found that the resilience to extreme drought decreased in mid-elevation and low productivity sites from 1980-1999 to 2000-2011 likely due to more frequent and severe droughts in the later period. Our study showed that the impact of drought on tree-level resilience was not dependent on its latitudinal location, but rather on the type of sites trees were growing at and on their growth performances (i.e., magnitude and variability of growth) during the predrought period. We found significant interactive effects between drought duration and tree growth prior to drought, suggesting that Scots pine trees with higher magnitude and variability of growth in the long term are more vulnerable to long and severe droughts. Moreover, our results indicate that Scots pine trees that experienced more frequent droughts over the long-term were less resistant to extreme droughts. We, therefore, conclude that the physiological resilience to extreme droughts might be constrained by their growth prior to drought, and that more frequent and longer drought periods may overstrain their potential for acclimation.}, language = {en} } @article{JochheimLuettschwagerRiek2022, author = {Jochheim, Hubert and L{\"u}ttschwager, Dietmar and Riek, Winfried}, title = {Stem distance as an explanatory variable for the spatial distribution and chemical conditions of stand precipitation and soil solution under beech (Fagus sylvatica L.) trees}, series = {Journal of Hydrology}, journal = {Journal of Hydrology}, number = {608}, publisher = {Elsevier}, issn = {0022-1694}, doi = {10.1016/j.jhydrol.2022.127629}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5306}, year = {2022}, abstract = {The partitioning of bulk precipitation (PR) in forest ecosystems and its chemical composition depends on both meteorological factors, such as precipitation amount and intensity, evaporation rate, and wind speed, and stand structural factors, such as stand density, canopy structure, bark texture, and spatiotemporal distribution and density of foliage. We analysed fluxes of water and element contained therein of a mature European beech (Fagus sylvatica L.) forest stand on sandy soils in northeastern Germany. We applied a radially symmetrical setup within a stem distance gradient to measure stand precipitation (SP) with its components of throughfall (TF) and stemflow (SF), as well as to measure soil moisture, the chemical composition of the soil solution, the soil chemistry, and the fine root distribution. The chemical analysis of the constituents covered the macroelements (Ca, Mg, K, Na, Al, Fe, Mn, Si, S, P), the cations and anions NH4+, NO3-, Cl-, SO42-, and a few heavy metals (Cu, Pb, Zn). With an average PR of 620 mm a-1, the partitioning resulted in 79\% TF, 6\% SF, and 15\% canopy interception. TF volume increased with distance to stem during summer, but decreased during winter. Clear spatial gradients with increasing concentrations from PR, to different classes of TF as the distance from the trunk decreased, to SF were observed for nearly all elements. The contact of precipitation with leaves and the canopy structures alters the chemical composition of TF and SF by transferring elements from dry deposition or leaching of intracellular materials from the canopy and leads to the input of larger amounts of macroelements and heavy metals with the SP into the soil. Spatial patterns of canopy structures thus affect the spatial variation of TF and its constituents, which also affects the spatial distribution of roots and, at least in phases, the chemical composition of the topsoil solution.}, language = {en} } @misc{ZicheGruenebergRieketal.2022, author = {Ziche, Daniel and Gr{\"u}neberg, Erik and Riek, Winfried and Wellbrock, Nicole}, title = {Vergleich der Daten der LUCAS 2015-Inventur und der zweiten Bodenzustandserhebung im Wald : Untersuchungen zur Vergleichbarkeit und Repr{\"a}sentanz zweier bodenkundlicher Inventuren in Deutschland}, series = {Th{\"u}nen Report; 94}, journal = {Th{\"u}nen Report; 94}, editor = {Johann Heinrich von Th{\"u}nen-Institut,}, publisher = {Th{\"u}nen-Institut, Bundesforschungsinstitut f{\"u}r L{\"a}ndliche R{\"a}ume, Wald und Fischerei}, isbn = {978-3-86576-239-9}, issn = {2196-2324}, doi = {10.3220/REP1651759791000}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5314}, pages = {62}, year = {2022}, abstract = {Die Produktivit{\"a}t von Wald{\"o}kosystemen wird durch die Bereitstellung von N{\"a}hrstoffen und Wasser gew{\"a}hrleistet.

Die Erhebungen fanden zwischen 1986 bis 1994 (BZE I-Wald) und 2006 bis 2008 (BZE II-Wald) nach einheitlichem Aufnahmeverfahren statt. Das LUCAS-Projekts zielt auf die Erstellung eines harmonisierten Datensatz zur Landbedeckung und Landnutzung innerhalb der Europ{\"a}ischen Union (EU). Das Europ{\"a}ische Datenzentrum (ESDAC) stellt 265.000 georeferenzierte Punkte auf einem 2 x 2 km-Raster bereit, die jeweils in den Jahren 2009 und 2015 an 10 \% der Punkte am gleichen Standort beprobt wurden. Angesichts von zwei parallellaufender Bodeninventuren stellt sich die Frage einer potentiellen Verkn{\"u}pfung miteinander. In dieser Studie werden die LUCAS-Bodendaten der Inventur des Jahres 2015 mit den entsprechenden bundesweiten BZE-Daten verglichen und auf ihre Repr{\"a}sentativit{\"a}t {\"u}berpr{\"u}ft. Um eine fl{\"a}chengewichtete Hochrechnung f{\"u}r Deutschland zu erm{\"o}glichen, erfolgte eine Zordnung der Inventurpunkte des LUCAS-Programms anhand ihrer Koordinaten zu den bei der bundesweiten BZE-Auswertung verwendeten 16 BZE-Substratklassen. Alle Klassen wurden hinsichtlich signifikanter und systematischer Unterschiede zwischen beiden Inventuren {\"u}berpr{\"u}ft. Dar{\"u}ber hinaus wurden die BZE-Daten dahingehend evaluiert, inwieweit die ausschließlich im LUCAS Programm verwendete Tiefenstufe 0-20 cm im Vergleich zum Mineralboden bis in 90 cm Tiefe und der Humusauflage bei der Berechnung von Vorr{\"a}ten zukommt. Der Vergleich der bodenchemischen Kennwerte ergab deutliche Unterschiede zwischen den Inventuren. Sowohl die pH(H2O)-Werte als auch die C/N-Verh{\"a}ltnisse waren bei LUCAS 2015 niedriger, die Konzentrationen von C und N jedoch h{\"o}her als bei der BZE II. Die Vorr{\"a}te an Kohlenstoff und Sticksoff weisen noch gr{\"o}ßere Abweichungen gegen{\"u}ber der BZE II aufgrund der Unsicherheiten bei der Ableitung von Trockenrohdichten aus Kartenmaterial auf. Im Gegensatz dazu erfolgte durch die BZE II eine volumenbezogene Beprobung an fast allen Standorten. Eine Ableitung von Trockenrohdichten aus Kartenmaterial f{\"u}hrt bei der LUCAS-Inventur zu einer hohen Unsicherheit der Ergebnisse und zu einer {\"U}bersch{\"a}tzung von Vorrats{\"a}nderungen. Die h{\"o}heren Kohlenstoff- und Stickstoffkonzentrationen bei der LUCAS-Inventur k{\"o}nnte an einer unzureichend genauen Trennung der organischen Auflage vom Mineralboden liegen, da dieser durch Bestandteile der Auflage aufkonzentriert w{\"u}rde. W{\"a}hrend der Erhebung der BZE-Wald wurde explizit auf die systematische Trennung beider Kompartimente geachtet. Weiterhin steht die Anzahl der beprobten LUCAS-Waldpunkte im Missverh{\"a}ltnis zur Waldfl{\"a}che, da in Nord- und S{\"u}ddeutschland zu wenig Probepunkte vorkamen. Allerdings sind die Waldanteile der LUCAS-Gesamtinventur mit denen der dritten Bundeswaldinventur vergleichbar. Die Stichprobengr{\"o}ße von LUCAS 2015 umfasst etwa 25 \% der BZE II-Stichprobe. Hierdurch sind einige Substrattypen nur unzureichend belegt, weshalb zum einen wesentliche Bodeneigenschaften unber{\"u}cksichtigt blieben und andererseits eine fl{\"a}chengewichtete Hochrechnung erschwert werden w{\"u}rde. Infolge der geringeren Stichprobe weichen die bodenchemischen Kennwerte der einzelnen Substratgruppen zwischen den Messnetzen ab. Außerdem erh{\"o}hen sich die Unsicherheiten durch die Reduzierung der Stichprobe. Somit ließen sich Bodenver{\"a}nderungen bei einer Wiederholungsinventur schwerer detektieren. Die Daten aus den Bodeninventuren sind f{\"u}r die Treibhausgasberichterstattung relevant, da Kohlenstoffvorr{\"a}ten f{\"u}r die organische Auflage und f{\"u}r den Mineralboden bis zu einer Tiefe von mindestens 30 cm zu berichten sind. Im Mittel werden nach den Daten der BZE II 16 \% des bis 90 cm Tiefe vorkommenden Kohlenstoffs in der Auflage gespeichert, wobei diese mit der LUCAS-Inventur nicht beprobt wurde. Der in der organischen Auflage gebundene Kohlenstoff ist vulnerabel gegen{\"u}ber Klima- und Umwelteinfl{\"u}ssen, so dass eine Auswertung diesbez{\"u}glich nicht m{\"o}glich ist.

Thus data related to climate change and its site specific drought effects on one hand and current soil nutrient status on the other is especially required to support decision making. Besides soil texture, soil organic carbon is one of the most important key factors controlling soil nutrient status (eg. cation-exchange capacity) and soil water storage (e.g. field capacity) in the glacial deposits of north eastern lowlands. In contrast to soil texture, which can be considered as stable over periods relevant to practical forest management, for mapping soil organic carbon and its distribution throughout the soil profile a more dynamic regionalization approach considering contemporary measurements is needed. For this purpose, data on contemporary soil organic carbon stocks is taken from the second National Forest Soil Inventory and additional regional sampling points in Brandenburg (Germany). Potential covariates representing the soil forming factors: parent material, organisms (vegetation), age, relief and climate are obtained with high spatial resolution from forest site mapping, forest inventory, digital terrain analysis and climate models. The proposed regionalization approach captures the concepts of SCORPAN modelling and depth functions. While for estimation of carbon stocks in the entire soil solum stepwise regression analysis and geostatistical techniques are involved, the methodology to derive and map relative depth functions is based on cluster analysis and classification tree approach. The intended benefits by splitting regionalisation into plot level and relative vertical depth gradients are to ensure consistency of solum stocks and single soil depths and to avoid the construction of artificial depth gradients. Furthermore, the procedure allows a straightforward interpretation of covariates in the sense of pedogenetic processes, which: (a) supports variable selection and exclusion of spurious covariates during model development and (b) may provide direct decision support regarding environmental and management effects on soil organic carbon. The obtained statistical models contain covariates related to all five soil forming factors. But, the conducted analyses especially point towards high influences of depth to groundwater table and mean slope of catchment area on soil organic carbon storage. Invoking geostatistical techniques shows no remaining variation, to be explained by spatial position and thus don't improve overall model performance. Cluster analysis of relative depth gradients results in five Clusters of acceptable heterogeneity. The highest differences between the clusters are observed across the portions of carbon stored in the forest floor.

Build4People's rationale is based on Phnom Penh's dynamic economic growth, which is coupled with a local urbanisation and construction boom. However, new buildings and neighbourhoods are rarely constructed in a sustainable way with direct and indirect negative environmental impacts. Issues of sustainability are hardly addressed by decision-makers in the construction sector, related ministries, city administrations or building users.

Therefore, in the further development of the cultural landscape and in the management of natural resources, special importance must be attached to the habitat demands of species and the preservation of ecosystem services. The study of ecosystem services has extended its influence into spatial planning and landscape ecology, the integration of which can offer an opportunity to enhance the saliency, credibility, and legitimacy of landscape ecology in spatial planning issues. Objective: This paper proposes a methodology to detect red deer habitats for e.g. huntable game. The model is established on remote sensing based value-added information products, the derived landscape structure information and the use of spatially and temporally imprecise in-situ data (e.g. available hunting statistics). In order to realize this, four statistical model approaches were developed and their predictive performance assessed. Methods: Altogether, our results indicate that based on the data mentioned above, modeling of habitats is possible using a coherent statistical model approach. All four models showed an overall classification of > 60\% and in the best case 71,4\%. The models based on logistic regression using preference data derived from 5-year hunting statistics, which has been interpreted as habitat suitability. The landscape metrics (LSM) will be calculated on the basis of the Global Forest Change dataset (HANSEN et al. 2013b ). The interpolation of landcover data into landscape-level was made with the software FRAGSTAT and the moving window approach. Correlation analysis is used to identify relevant LSM serving as inputs; logistic regression was used to derive a final binary classifier for habitat suitability values. Three model variations with different sets of LSM are tested using the unstandardized regression coefficient. Results lead to an insight of the effect of each LSM but not on the strength of the effect. Furthermore, the predicted outcome is rather difficult to interpret as different units and scales for each LSM are used. Hence, we calculated the fourth model using the standardized regression coefficient. It harmonized the measurement units of the LSM and thus allowed a better comparison, interpretation, and evaluation.Conclusion: Our research reveals that applying a statistical model using coarse data is effective to identify potential red deer habitats in a significant qualitative manner. The presented approach can be analogously applied to other mammals if the relevant structural requirements and empirical habitat suitability data (e.g. home range, biotopes, and food resources) are known. The habitat preferences of red deer are best described by LSM concerning area-relation and wildlifeedge relations. Most important are edges between meadows, pastures or agricultural field and forest, as well as short paths between those elements for food resources. A large proportion of forest is important for species survival and positively influences the occurrence of red deer. Outcomes help to understand species habitat relation and on which scale wildlife perceives the landscape. In addition, they support the practical habitat management and thus the overall species diversity.}, language = {en} } @article{BoeneckeMeyerVogeletal.2020, author = {B{\"o}necke, Eric and Meyer, Swen and Vogel, Sebastian and Schr{\"o}ter, Ingmar and Gebbers, Robin and Kling, Charlotte and Kramer, Eckart and L{\"u}ck, Katrin and Nagel, Anne and Philipp, Golo and Gerlach, Felix and Palme, Stefan and Scheibe, Dirk and Zieger, Karin and R{\"u}hlmann, J{\"o}rg}, title = {Guidelines for precise lime management based on high-resolution soil pH, texture and SOM maps generated from proximal soil sensing data}, series = {Precision Agriculture}, volume = {22}, journal = {Precision Agriculture}, publisher = {Springer Nature}, issn = {1385-2256}, doi = {10.1007/s11119-020-09766-8}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-4890}, pages = {493 -- 523}, year = {2020}, abstract = {Soil acidification is caused by natural paedogenetic processes and anthropogenic impacts but can be counteracted by regular lime application.

Therefore, this study aimed to provide guidelines for site-specific liming based on proximal soil sensing. First, high-resolution soil maps of the liming-relevant indicators (pH, soil texture and soil organic matter content) were generated using on-the-go sensors. The soil acidity was predicted by two ion-selective antimony electrodes (RMSEpH: 0.37); the soil texture was predicted by a combination of apparent electrical resistivity measurements and natural soil-borne gamma emissions (RMSEclay: 0.046 kg kg-1); and the soil organic matter (SOM) status was predicted by a combination of red (660 nm) and near-infrared (NIR, 970 nm) optical reflection measurements (RMSESOM: 6.4 g kg-1). Second, to address the high within-field soil variability (pH varied by 2.9 units, clay content by 0.44 kg kg-1 and SOM by 5.5 g kg-1), a well-established empirical lime recommendation algorithm that represents the best management practices for liming in Germany was adapted, and the lime requirements (LRs) were determined. The generated workflow was applied to a 25.6 ha test field in north-eastern Germany, and the variable LR was compared to the conventional uniform LR.

However, soil-base titrations for BNC determination are too laborious to be extensively applied in routine soil testing. In contrast, visible and near-infrared spectroscopy (visNIRS) is a time and cost-effective alternative that can analyze several soil characteristics within a single spectrum. VisNIRS was tested in the laboratory on 170 air-dried and sieved soil samples of nine agricultural fields of a quaternary landscape in North-east Germany predicting the soil's BNC and the corresponding lime requirement (LRBNC) at a target pH of 6.5. Seven spectral pre-processing methods were tested including a new technique based on normalized differences (ND). Furthermore, six multivariate regression methods were conducted including a new method combining a forward stagewise subset selection algorithm with PLSR (FS-PLSR).

The best regression model for most target variables was FS-PLSR combined with the second Savitzky-Golay derivation as pre-processing method achieving R2s from 0.68 to 0.82.

The findings from ProAkis (2015) show that different types of organisations such as administrative offices, public or semi-public advisory services, rural academies/universities, producer organisations, other NGOs or private consultants engaged in the Agricultural Knowledge and Innovation System (AKIS) can act as ISS. The funding of ISS can be public, private or a mix of both. A literature review indicates that studies often focus on the larger "enabling environment" and the structure of the Agricultural Knowledge and Innovation Systems (AKIS). Moreover, many authors pay particular attention to the role of public or semi-public farm advisory organisations (Knierim et al., 2015; Sulaiman 2015). The paper is based on the analysis of more than 200 case studies of publically or privately funded interactive innovation projects within the EU and beyond. The selection of cases took place under the framework of the Horizon2020-funded European research and innovation project LIAISON. European and national databases contain several thousands of projects in agriculture, forestry and rural development. We selected projects applying the interactive innovation approach from a) EU programmes (EIP-Agri, Horizon2020, Interreg, and LIFE+); b) nationally/regionally or privately funded projects; and c) informal initiatives or networks in the agri-food, forestry, bioeconomy or nature conservation area. The results indicate that publically funded IIS play a core role for legal/administrative compliance of projects. Semi-public advisory services take up this role as well, and they are strong in linking farmers with scientists, technicians, entrepreneurs etc. However, they often exist and offer efficient ISS only for those industries that have a long tradition for a sector or area (e.g. dairy, pork, poultry or club fruit). This paper shows that different types of organisations (research institutes, farmers or producer organisations, NGOs, processing or marketing SMEs, or public bodies) provide various forms of support for the studied interactive innovation groups. No particular type of organisation such as the farm advisory services are more suitable than the other organisations for the delivery of ISS. Instead, it depends on former collaboration, the particular topic, objective or capacities available as well as the cultural/political context who engages in interactive innovation and provides innovation support.}, language = {en} } @article{WeissMichlerGillichetal.2022, author = {Weiss, Fabio and Michler, Frank Uwe and Gillich, Benjamin and Tillmann, J{\"o}rg and Ciuti, Simone and Heurich, Marco and Rieger, Siegfried}, title = {Displacement Effects of Conservation Grazing on Red Deer (Cervus elaphus) Spatial Behaviour}, series = {Environmental Management}, volume = {70}, journal = {Environmental Management}, publisher = {Springer Nature}, issn = {0364-152X}, doi = {10.1007/s00267-022-01697-6}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-4609}, pages = {763 -- 779}, year = {2022}, abstract = {Conservation grazing uses semi-feral or domesticated herbivores to limit encroachment in open areas and to promote biodiversity. However, we are still unaware of its effects on wild herbivores. This study investigates the influence of herded sheep and goats on red deer (Cervus elaphus) spatial behavior by testing three a-priori hypotheses: (i) red deer are expected to avoid areas used by livestock, as well as adjacent areas, when livestock are present, albeit (ii) red deer increase the use of these areas when sheep and goats are temporarily absent and (iii) there is a time-lagged disruption in red deer spatial behavior when conservation grazing practice ends. Using GPS-telemetry data on red deer from a German heathland area, we modelled their use of areas grazed by sheep and goats, using mixed-effect logistic regression. Additionally, we developed seasonal resource selection functions (use-availability design) to depict habitat selection by red deer before, during, and after conservation grazing. Red deer used areas less during conservation grazing throughout all times of the day and there was no compensatory use during nighttime. This effect mostly persisted within 21 days after conservation grazing. Effects on habitat selection of red deer were detectable up to 3000 meters away from the conservation grazing sites, with no signs of either habituation or adaption. For the first time, we demonstrate that conservation grazing can affect the spatio-temporal behavior of wild herbivores.

Due to the low level of financial intermediation, community financing is characterized by close relations between investors and investees. Against this background, we apply the proximity concept from economic geography to explore spatial and relational aspects of community financing in the German organic agri-food sector. Based on a qualitative multiple case study approach, we find that the relevance of proximity is twofold.

One important way in which canteens can contribute to this transformation is by increasing the share of organic and local products. These new political and public demands contrast with the organizational development of canteens over the past few decades, which has mainly been characterized by an increase in economic efficiency and a reduction in costs. Based on a project that was carried out in the Berlin-Brandenburg region (Germany), this paper exemplifies some of the challenges canteens face in the process of introducing organic and local products. Methods The empirical results are based on 31 qualitative interviews with canteen managers and kitchen staff as well as with the processing company involved. In addition, a survey of 500 canteen guests was conducted in the participating canteens. Results The analysis shows that the canteens had to adapt various organizational practices to ensure a healthy and sustainable diet at manageable cost. Introducing local organic beef in the canteens requires close cooperation with local farmers and processors, a change in procurement practices, transparency around the origin of the products, as well as adapted menu planning. Discussion Based on the empirical results, the paper discusses how these challenges can be met and which supportive measures can be taken on different governance levels. To change entrenched practices, process facilitators who support local cooperation along the value added chain are needed, and practical knowledge and professional training must be provided.

To advance the diffusion of this niche innovation into general teacher education, this article offers a systematic literature review based on a qualitative analysis of 158 peer-reviewed publications on TESD research. Our results show that TESD research is a growing field characterized by five types of inquiry: designing learning environments, understanding learner attributes, measuring learning outcomes, promoting systems change, and advancing visions for the field. Major innovation potentials of TESD for more general teacher education are its emphasis on the grand socio-environmental challenges of our times, methodologies to engage with knowledge diversity (e.g., inter/transdisciplinarity), and sustainability science learning approaches (e.g., backcasting).

Important benefits of combining tree growth with agricultural crops and/or forage production systems include higher biodiversity through more diverse habitats, the control of runoff and soil erosion, the augmentation of soil water availability, the creation of microclimates, carbon sequestration and provision of a more diverse farm economy. As the climate changes, north eastern Germany is likely to be particularly prone to severe effects from droughts and wind erosion in the future. However, the area of land under agroforestry makes up less than 2\% of the total agricultural area in Germany. Through qualitative interviews with key actors, this study analyzed the benefits of, potentials for and barriers to implementing agroforestry systems in the federal state of Brandenburg. Results showed that agroforestry systems have significant potential in relation to several benefits, particularly the mitigation of soil erosion and stabilization of microclimate regimes. Additionally, agroforestry has the potential to provide wood for energy production or material uses.

However, the best management practice for liming in Germany only insufficiently considers within-field soil variability. Thus, a site-specific variable rate liming strategy was developed and tested on nine agricultural fields in a quaternary landscape of north-east Germany. It is based on the use of a proximal soil sensing module using potentiometric, geoelectric and optical sensors that have been found to be proxies for soil pH, texture and soil organic matter (SOM), which are the most relevant lime requirement (LR) affecting soil parameters. These were compared to laboratory LR analysis of reference soil samples using the soil's base neutralizing capacity (BNC). Sensor data fusion utilizing stepwise multi-variate linear regression (MLR) analysis was used to predict BNC-based LR (LRBNC) for each field. The MLR models achieved high adjusted R2 values between 0.70 and 0.91 and low RMSE values from 65 to 204 kg CaCO3 ha-1. In comparison to univariate modeling, MLR models improved prediction by 3 to 27\% with 9\% improvement on average. The relative importance of covariates in the field-specific prediction models were quantified by computing standardized regression coefficients (SRC). The importance of covariates varied between fields, which emphasizes the necessity of a field-specific calibration of proximal sensor data. However, soil pH was the most important parameter for LR determination of the soils studied. Geostatistical semivariance analysis revealed differences between fields in the spatial variability of LRBNC. The sill-to-range ratio (SRR) was used to quantify and compare spatial LRBNC variability of the nine test fields. Finally, high resolution LR maps were generated. The BNC-based LR method also produces negative LR values for soil samples with pH values above which lime is required. Hence, the LR maps additionally provide an estimate on the quantity of chemically acidifying fertilizers that can be applied to obtain an optimal soil pH value.}, language = {en} } @article{SchultzGlemnitzStachowetal.2022, author = {Schultz, Alfred and Glemnitz, Michael and Stachow, Ulrich and Schwierz, Friederike}, title = {Changes in a Bird Community in an Agricultural Landscape in Northeast Germany between 1999 and 2015}, series = {Land}, volume = {11}, journal = {Land}, number = {12}, editor = {Petri{\c{s}}or, Alexandru-Ionuţ}, publisher = {MDPI}, issn = {2073-445X}, doi = {10.3390/land11122115}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-3750}, year = {2022}, abstract = {Temporal changes in the bird community of an agricultural landscape in northeast Germany were analysed covering three different analytical foci (landscape-wide, habitat types, sample plots) and two aggregation levels of bird observation data (whole bird community, bird guilds).

Our analyses address the question of how changes in the occurrences of agricultural birds (numbers of species and of individuals) at local spots manifest themselves in the landscape as a whole. By summarizing all findings concerning single variables (number of species, observation frequencies, abundances, different habitat types, bird guilds), a dramatic, systematic decline of the bird community at sample plots was discovered between the campaigns, which is not yet recognisable across the whole landscape in terms of species richness. Furthermore, we found that landscape-wide, the birds' use of habitat changed; the variability between single sample plots increased strongly and most species occurred at fewer sample plots over the whole landscape. Obviously, sample plots with high bird occurrences are becoming more relevant for maintaining bird communities over the whole landscape.

Here, we reflect on the importance of feralization in the relationship between ongoing urbanization and the worsening biodiversity crisis. Feralization is often viewed as the exact opposite of a domestication process—a perception that we argue is too simplistic. The interrelations between domestication, feralization, and the adaptation of taxa to novel, human-made environments such as cities are complex. Given their unique traits, feral(izing) taxa can play key roles in sustainability, sometimes problematic (i.e., invasive species) but at other times, improving human well-being in urban settings. Abstract Domestication describes a range of changes to wild species as they are increasingly brought under human selection and husbandry. Feralization is the process whereby a species leaves the human sphere and undergoes increasing natural selection in a wild context, which may or may not be geographically adjacent to where the originator wild species evolved prior to domestication. Distinguishing between domestic, feral, and wild species can be difficult, since some populations of so-called "wild species" are at least partly descended from domesticated "populations" (e.g., junglefowl, European wild sheep) and because transitions in both directions are gradual rather than abrupt. In urban settings, prior selection for coexistence with humans provides particular benefit for a domestic organism that undergoes feralization. One risk is that such taxa can become invasive not just at the site of release/escape but far away. As humanity becomes increasingly urban and pristine environments rapidly diminish, we believe that feralized populations also hold conservation value.}, language = {en} } @article{MarkowFieldsendvonMuenchhausenetal.2023, author = {Markow, Jekaterina and Fieldsend, Andrew and von M{\"u}nchhausen, Susanne and H{\"a}ring, Anna Maria}, title = {Building agricultural innovation capacity from the bottom up: Using spillover effects from projects to strengthen agricultural innovation systems}, series = {Agricultural Systems}, journal = {Agricultural Systems}, number = {209}, publisher = {Elsevier}, issn = {0308-521X}, doi = {10.1016/j.agsy.2023.103670}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6853}, pages = {10}, year = {2023}, abstract = {CONTEXT Current research emphasises that agricultural innovation projects are influenced in multiple ways by the Agricultural Innovation Systems (AIS) in which they operate. Yet little attention has been paid to the reverse direction of this relationship, i.e. how agricultural innovation projects affect AIS in the course of their innovative activities. Accordingly, there are currently no tools to measure such AIS spillovers from agricultural innovation projects. OBJECTIVE This paper shows that even where agricultural innovation projects have not been designed with the explicit aim of influencing AIS they can have spillovers on the AIS in which they operate. Based on this finding, it argues that designing agricultural innovation projects in a way that maximises such positive and reduces negative AIS spillovers would be a useful tool for strengthening agricultural innovation capacities in a particular territory or sector. METHODS Based on the concept of agricultural innovation projects as Organisational Innovation Systems (OIS) that are embedded in AIS, the paper develops an analytical framework for assessing spillovers of such projects on AIS and applies it to a case study of an Operational Group in the German Federal State of Hessen. RESULTS AND CONCLUSIONS The case study shows that agricultural innovation projects may yield diverse spillovers on the AIS in which they operate. In addition to considering how agricultural innovation projects are shaped - constrained and/or enabled - by AIS, the research community on agricultural innovation should pay more attention to this side of the interrelation of AIS and agricultural innovation projects. Designing agricultural innovation projects responsibly so that spillovers on AIS are monitored can help to improve national or sectoral AIS. SIGNIFICANCE This paper points to an underexplored issue in research on agricultural innovation and, related to this, a thus far unused potential policy tool for improving national and sectoral AIS. It further develops the concept of innovation projects as OIS into an approach for assessing the effects of projects on AIS; an area of project assessment that until now has not been adequately covered.}, language = {en} } @article{CreamerHagensBaartmanetal.2021, author = {Creamer, Rachel E. and Hagens, Mathilde and Baartman, Jantiene and Helming, Katharina}, title = {Editorial for special issue on "understanding soil functions - from ped to planet"}, series = {European Journal of Soil Science}, volume = {72}, journal = {European Journal of Soil Science}, number = {4}, publisher = {Wiley}, issn = {1365-2389}, doi = {10.1111/ejss.13099}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6870}, pages = {1493 -- 1496}, year = {2021}, language = {en} } @misc{WolfNoeltingHammetal.2022, author = {Wolf, Nicole and N{\"o}lting, Benjamin and Hamm, Andrea and Rehak, Rainer and Hobelsberger, Christine and Beer, Felix}, title = {Kommunale Plattformen nachhaltig gestalten : Kriterienkatalog f{\"u}r Plattformen im Dienst einer nachhaltig-digitalen Daseinsvorsorge}, series = {Kurzstudie der Forschungslinie „Zukunftsf{\"a}hige Daseinsvorsorge"}, journal = {Kurzstudie der Forschungslinie „Zukunftsf{\"a}hige Daseinsvorsorge"}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6641}, pages = {54}, year = {2022}, abstract = {Digitale Plattformen avancieren zu einem wichtigen Teil der kommunalen Daseinsvorsorge.

Although various research approaches have tackled technological innovations in the last few decades, the specificities and enabling conditions of individual sustainability innovations remain rather unknown. We therefore propose an analytical framework, built on learning from the social-ecological systems and transitions literature. The sustainability innovation framework features four dimensions: context, actors, process and outcomes, which are detailed in 31 variables. We use the sustainability innovation framework to analyze two case studies selected in the Schorfheide-Chorin Biosphere Reserve, Germany. The first refers to technological and organizational innovation in mobility, while the second relates to social and organizational innovation in agriculture. As a result, we highlight commonalities and differences in enabling conditions and variables between the two cases, which underpin the influence of trust, commitment, resource availability, experimenting, learning, advocating, and cooperating for innovation development. The cases further demonstrate that sustainability innovations develop as bundles of interdependent, entangled novelties, due to their disruptive character. Their specificity thereby resides in positive outcomes in terms of social-ecological integrity and equity. This study therefore contributes to transitions studies via a detailed characterization of sustainability innovations and of their outcomes, as well as through a generic synthesis of variables into an analytical framework that is applicable to a large and diverse range of individual sustainability innovations. Further empirical studies should test these findings in other contexts, to pinpoint generic innovation development patterns and to develop a typology of sustainability innovation archetypes.}, language = {en} } @article{Molitor2022, author = {Molitor, Heike}, title = {Wenn Stadtkinder Zeit haben: Naturerfahrungen im freien Spiel}, series = {Zeitpolitisches Magazin}, volume = {19}, journal = {Zeitpolitisches Magazin}, number = {40}, publisher = {Deutsche Gesellschaft f{\"u}r Zeitpolitik Gemeinn{\"u}tziger e.V.}, issn = {2196-0356}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6633}, pages = {29 -- 31}, year = {2022}, language = {de} } @techreport{DickhutStrasdasGoergeetal.2023, author = {Dickhut, Heike and Strasdas, Wolfgang and Goerge, Marius and Schulze D{\"u}ding, Johanna}, title = {Messung der Nachhaltigkeit des Tourismus in Deutschland}, number = {73}, editor = {Umweltbundesamt,}, publisher = {Umweltbundesamt}, address = {Dessau-Roßlau}, issn = {1862-4804}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6531}, pages = {350}, year = {2023}, abstract = {Mit dem hier vorgelegten Projekt wurden zwei Hauptziele verfolgt.

Das TSSA erlaubt somit eine systematische Zuordnung der {\"o}konomischen, {\"o}kologischen und sozialen Auswirkungen des Tourismus zu den tourismusrelevanten Wirtschaftszweigen auf nationaler Ebene. Im Ergebnis der TSSA-Aktualisierung zeigt sich, dass der Tourismus in Deutschland weiterhin signifikant zur Wertsch{\"o}pfung und zur Schaffung von Arbeitspl{\"a}tzen beitr{\"a}gt. Rund 3,6 \% bzw. 6,1 \% der Gesamtbruttowertsch{\"o}pfung und -besch{\"a}ftigung standen im Jahr 2019 im Zusammenhang mit dem Tourismus. Die Arbeitsproduktivit{\"a}t im Tourismussektor ist allerdings weiterhin relativ gering. Bei den {\"o}kologischen Auswirkungen zeigt sich ein im Vergleich zur letzten Messung (mit Daten von 2015 oder 2016) leicht gestiegener Energieverbrauch bei allerdings zur{\"u}ckgehender Energieintensit{\"a}t. Diese ist im Tourismus {\"a}hnlich hoch wie im Durchschnitt der deutschen Volkswirtschaft. Bei den tourismusinduzierten Emissionen von Treibhausgasen (THG) und besonders bei der Emissionsintensit{\"a}t sind ebenfalls Verbesserungen zu beobachten, doch liegt die Emissionsintensit{\"a}t der Tourismuswirtschaft immer noch deutlich {\"u}ber dem volkswirtschaftlichen Durchschnitt. Innerhalb der deutschen Tourismuswirtschaft tr{\"a}gt weiterhin der Verkehrssektor (insb. Flug- und Schiffsverkehr) am st{\"a}rksten zum Energieverbrauch und zu den THG-Emissionen bei. Dagegen ist der tourismusinduzierte Wasserverbrauch deutschlandweit als eher unproblematisch einzusch{\"a}tzen. Die Wasserintensit{\"a}t des Tourismus liegt deutlich unter dem Durchschnitt der deutschen Volkswirtschaft. Innerhalb des Tourismus ist sie am h{\"o}chsten in den Sektoren Beherbergung und Gastronomie. Bez{\"u}glich der sozialen Nachhaltigkeitsdimension ist der relativ geringe und im Zeitverlauf abnehmende Verdienstabstand zwischen M{\"a}nnern und Frauen (bekannt als Gender Pay Gap; hier unbereinigt) in der Tourismuswirtschaft hervorzuheben. Alle anderen Kennzahlen in Bezug auf die Arbeitsbedingungen im Tourismus fallen dagegen weiterhin eher negativ aus. Dementsprechend werden diese von den Besch{\"a}ftigten der Branche im Vergleich zum Durchschnitt der deutschen Gesamtwirtschaft als schlechter eingesch{\"a}tzt. Bereits w{\"a}hrend der vorangegangenen Projektphase zeigte sich, dass f{\"u}r einige Nachhaltigkeitsindikatoren, vor allem aus dem {\"o}kologischen Bereich, eine Ber{\"u}cksichtigung im Rahmen des TSSA-Ansatzes nicht uneingeschr{\"a}nkt m{\"o}glich ist. Dies liegt unter anderem an der unzureichenden Datenlage in der amtlichen Statistik sowie der Komplexit{\"a}t, bestimmte {\"o}kologische Effekte kausal dem Tourismus zuzuordnen. Daher wurde im zweiten Teil des hier vorgelegten Projekts f{\"u}r die Umweltindikatoren „Biodiversit{\"a}t", „Wasserqualit{\"a}t", „L{\"a}rmbelastung", „Fl{\"a}cheninanspruchnahme", „Luftemissionen" und „Abfallaufkommen" sowie f{\"u}r den sozialen Indikator „Tourismusakzeptanz" eine ausf{\"u}hrliche Recherche bestehender Datengrundlagen durchgef{\"u}hrt und darauf aufbauend evaluiert, inwieweit alternative Bilanzierungsans{\"a}tze - als Erg{\"a}nzung zum TSSA-Messsystem - den Tourismuseffekt abbilden k{\"o}nnen.

Human health may be at risk when soils are contaminated; while some soil contaminants such as heavy metals (HMs) have been extensively studied, others such as micro(nano)plastics (MNPs) or antibiotic-resistant bacteria (ARB) pose novel threats. This paper investigates the linkages between soil contamination and human health risk by reviewing the state of knowledge on HMs, MNPs, and ARB in agricultural soils. A keyword-based search in Web of Science, Scopus, and Google Scholar was conducted, complemented with a backward snowball search. We analysed main sources of contamination for agricultural soils, risks to human health differentiated by uptake pathway (ingestion, inhalation, dermal), and interactions of contaminants with microorganism, soil fauna, and plants. Results show that the emergence and spread of ARB and antibiotic resistant genes from agricultural soils and their contribution to antibiotic resistances of human pathogens is recognized as a significant threat. Likewise, a growing body of evidence indicates that MNPs are able to enter the food chain and to have potentially harmful effects on human health. For HM, knowledge of the effects on human health is well established. Multiple agricultural practices increase HM concentrations in soils, which may lead to adverse health effects from the ingestion of contaminated products or inhalation of contaminated soil particles. Severe knowledge gaps exist about the pathways of the contaminants, their behaviour in soil, and human uptake. Little is known about long-term exposure and impacts of MNPs, antibiotics and ARB on human health or about the possible combined effects of MNPs, ARB, and HMs. Missing monitoring systems inhibit a comprehensive assessment of human health risks.

Current Nationally Determined Contributions under the Paris Agreement are insufficient to avoid the irreversible loss of critical island ecosystems. Existing research, policies, and finance also do not sufficiently address small islands' social-environmental challenges. For instance, the new Global Biodiversity Framework (GBF) mentions islands in the invasive species management target. This focus is important, as islands are at high risk to biological invasions; however, this is the only GBF target that mentions islands. There are threats of equal or greater urgency to small islands, including coastal hazards and overexploitation. Ecosystems such as coral reefs and mangroves are crucial for biodiversity, coastal protection, and human livelihoods, yet are unaddressed in the GBF. While research and global policy, including targeted financial flows, have a strong focus on Small Island Developing States (SIDS), the situation of other small islands has been largely overlooked. Here, through a review of policy developments and examples from islands in the Philippines and Chile, we urge that conservation and climate change policies place greater emphasis on acknowledging the diversity of small islands and their unique governance challenges, extending the focus beyond SIDS. Moving forward, global policy and research should include the recognition of small islands as metacommunities linked by interacting species and social-ecological systems to emphasize their connectivity rather than their isolation. Coalition-building and knowledge-sharing, particularly with local, Indigenous and traditional knowledge-holders from small islands, is needed to meet global goals on biodiversity and sustainable development by 2030.}, language = {en} } @misc{TarneBatjavMatiasetal.2022, author = {Tarne, Anika and Batjav, Batbuyan and Matias, Denise Margaret and Mehring, Marion}, title = {Rural to urban migration in Mongolia - Social-ecological conditions for a stepwise process}, series = {ISOE-Diskussionspapiere}, journal = {ISOE-Diskussionspapiere}, number = {47}, address = {Frankfurt am Main}, issn = {1436-3534}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6728}, pages = {17}, year = {2022}, abstract = {Since the 1990s, Mongolia's capital city Ulaanbaatar has recorded steady and rapid population growth due to rural-urban migration.

While social factors (kinship, education) show the same relevance at each step of migration, ecological factors such as the occurrence of dzud seem more relevant at the early stages, from the steppe to the sum centres.

We then reflect on the legitimacy of ecosystem comparisons beyond the borders of biogeographical regions—an important prerequisite for global approaches. In the following, we present two case scenarios that exemplarily illustrate the topic from different perspectives: carnivore-livestock conflicts (classical view, human perspective) and wind turbine-induced mortality of bats (wildlife perspective, rarely regarded as a form of HWC). On this basis, we try to develop a framework that enables a global approach, while adequately considering case- and region-specificity. We think that a globally valid and generally approachable dimension can be defined, as long as there is a natural link: in the present case the established monophyly of the orders Carnivora and Chiroptera, i.e., representatives descending from common ancestors, thus sharing common ecological features.

We show that foraging and social call activity of commonly occurring bat species was lower in urban areas compared to rural areas. We present data on rural-urban variation in acoustic parameters of echolocation and Type D social calls (produced during flight) using the example of the common pipistrelle Pipistrellus pipistrellus. Calls from urban sites revealed significantly higher end and peak frequencies compared to rural site calls. In addition, urban social calls present a higher degree of complexity as they structurally differed from rural social calls with regard to assemblage and number of call components. Moreover, urban social calls were emitted in a presumably different context than rural calls: antagonistic social calls in urban areas were detected throughout the year and in the acoustic absence of conspecifics and heterospecifics. Our results provide evidence for the ability of P. pipistrellus to modulate temporal and spectral features of echolocation and social calls, as well as patterns of social call production, in order to compensate for constraints imposed by the urban acoustic environment.

The tree data to calculate timber and wood volumes stem from a dataset with 728 single trees from a relevant range of climatic conditions. Results: The potential annually available timber volumes from tree windbreaks with 500 m spacing are 2.9 million m3 for Central Asia as a whole and 1.5 million m3 for Uzbekistan alone, which is 5 times the current domestic roundwood production and imports of the country.

The large forests dominated by Scots pine (Pinus sylvestris L.) that cover the lowland regions in northeast Germany have already been affected regularly by cyclic mass propagations of defoliating insect species in the past with climate projections implying an even more advantageous environment for devastating outbreaks in the future. To improve predictive and responsive capacities we have investigated a wide range of ecological parameters to identify those most strongly related to past outbreak waves of three central species. In total, we analyzed 3,748 variables covering stand and neighborhood properties, site quality, and climatic conditions for an area of roughly 750,000 ha of pine forests in the period 2002-2016. To reflect sensitivity against varying climate, we computed "floating windows" in relation to critical phenological phases of the respective insects. The parameters with the highest explanatory power resulted from the variable importance measures of the Random Forest (RF) methodology and have been evaluated by a 10-fold cross-validation process. Our findings closely reflect the known specific gradation patterns and show that relative variable importance varies with species. While Lymantria monacha L. feeding was mainly dependent on the surroundings of the respective stand, Diprion pini L. proved to be almost exclusively susceptible to climatic effects in its population dynamics. Dendrolimus pini L. exhibited a mixed pattern of variable importance involving both climatic and forest structure parameters. In many cases the obtained statistical results support well-known ecological cause-effect relations and long-term population change dynamics. The RF delivered very high levels of sensitivity and specificity in the developed classifications and proved to be an excellent tool to handle the large amounts of data utilized for this study.

The field internal magnitude of spatial variability and hidden correlations between the variables of investigation were analyzed by means of geostatistics and boundary-line analysis to elucidate the influence of soil pH and ECa on the spatial distribution of biomass. Biomass and pH showed high spatial variability, which necessitates high resolution data acquisition of soil and plant properties.

With recent advances in Unmanned Aerial Vehicle (UAV) remote sensing technologies, the possibility to acquire accurate tree heights semi-automatically has become a reality. In this study, photogrammetric and field-based tree height measurements of a Scots Pine stand were validated using destructive methods. The intensive forest monitoring site implemented for the study was configured with permanent ground control points (GCPs) measured with a Total Station (TS). Field-based tree height measurements resulted in a similar level of error to that of the photogrammetric measurements, with root mean square error (RMSE) values of 0.304 m (1.82\%) and 0.34 m (2.07\%), respectively (n = 34). A conflicting bias was, however, discovered where field measurements tended to overestimate tree heights and photogrammetric measurements were underestimated. The photogrammetric tree height measurements of all trees (n = 285) were validated against the field-based measurements and resulted in a RMSE of 0.479 m (2.78\%). Additionally, two separate photogrammetric tree height datasets were compared (n = 251), and a very low amount of error was observed with a RMSE of 0.138 m (0.79\%), suggesting a high potential for repeatability. This study shows that UAV photogrammetric tree height measurements are a viable option for intensive forest monitoring plots and that the possibility to acquire within-season tree growth measurements merits further study.

Through the reconstruction of the historical and current distribution and movement patterns of seven LH species in five periods, we investigate possible changes in distribution and movement patterns over time. Data collection is based on a systematic literature search, censuses reports, online databases, dung count transects, and camera trap surveys. We mapped all LH observations and movements using ArcGIS 10.1. Our results reveal a dramatic collapse of LH populations between the peak of the colonial period and the post-colonial/civil war period (1800-2001), followed by a slight recovery from the post-proclamation of Great Limpopo Transfrontier Park to the current period (2002-2021).

Data analysis and conceptualization followed a grounded theory approach. Findings The development process of value chains occurs in three phases, from joint exploration of the problem, through a phase of experimentation and implementation, to further cultivation of established collaborations among value chain actors. The development process oscillates between intra- and inter-organizational learning as well as explorative and exploitative activities. Practical implications The results of this study can help to understand and to further professionalize the practice of value chain development and provide guidance for facilitators and other stakeholder working in this field.
