This will require the industry to half emissions to 2030, and to reach net-zero by mid-century. Mitigation requires consideration of four dimensions, the Scales, Scopes, Stakeholders and Strategies of carbon management. The paper provides a systematic review of these dimensions and their interrelationships, with a focus on emission inventory comprehensiveness; allocation principles at different scales; clearly defined responsibilities for decarbonization; and the identification of significant mitigation strategies. The paper concludes that without mitigation efforts, tourism will deplete 40\% of the world's remaining carbon budget to 1.5 °C. Yet, the most powerful decarbonization measures face major corporate, political and technical barriers. Without worldwide policy efforts at the national scale to manage the sector's emissions, tourism will turn into one of the major drivers of climate change.}, language = {en} } @book{ZbaraszewskiBalasDmytrowetal.2022, author = {Zbaraszewski, Wojciech and Balas, Martin and Dmytr{\´o}w, Krzysztof and Majewska, Agnieszka and Mayer, Marius and Steingrube, Wilhelm}, title = {Socio-economic research in protected areas of the Euroregion Pomerania: Visitor satisfaction, economic impacts and park-people relationships}, publisher = {Bogucki Wydawnictwo Naukowe}, address = {Poznań}, isbn = {978-83-7986-420-1}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6541}, publisher = {Hochschule f{\"u}r nachhaltige Entwicklung Eberswalde}, pages = {222}, year = {2022}, language = {en} } @article{DabardMann2023, author = {Dabard, Caroline H{\´e}l{\`e}ne and Mann, Carsten}, title = {Sustainability innovations: a proposal for an analytical framework and its empirical application in the Schorfheide-Chorin Biosphere Reserve}, series = {Sustainability Science}, volume = {18}, journal = {Sustainability Science}, number = {3}, publisher = {Springer Nature}, issn = {1862-4057}, doi = {10.1007/s11625-022-01241-9}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6558}, pages = {1085 -- 1098}, year = {2023}, abstract = {Sustainability innovations influence societal transformations through the development of new products, processes, organizations, behaviors or values.

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{MadakiLehbergerBavorovaetal.2023, author = {Madaki, Mustapha Yakubu and Lehberger, Mira and Bavorova, Miroslava and Igbasan, Boluwatife Teniola and K{\"a}chele, Harald}, title = {Effectiveness of pesticide stakeholders' information on pesticide handling knowledge and behaviour of smallholder farmers in Ogun State, Nigeria}, series = {Environment, Development and Sustainability}, journal = {Environment, Development and Sustainability}, publisher = {Springer Nature}, doi = {10.1007/s10668-023-03332-8}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8213}, pages = {20}, year = {2023}, abstract = {Although pesticides ensure the quality and quantity of agricultural produce, they have adverse effects on farmers, their families, and consumers.

One hundred and fifty-six farmers were interviewed using a structured questionnaire in December 2019 and January 2020.

The majority of farmers never use respirators (79\%), hats (60\%), and boots (57\%) when applying pesticides. Knowledge of pesticide application and waste management is low (58\% of respondents scored less than 10 on a knowledge scale of 0-14). The result of the regression model shows that information from pesticide labels and farmer-to-farmer exchanges significantly increase farmers' knowledge of pesticide handling and PPE use. Our results suggest that the effectiveness of current information provision to smallholder farmers on the correct use of pesticides is not sufficient.

Multistage sampling was used to collect data from 400 households in three agro-ecological zones of Nepal.

The results of our study showed that farmers in the Mountain region are more likely to adopt off-farm activities and temporary migration as a CCA strategy than those in the Terai/plain agro-ecological zone. In the Terai/Plain, farmers mainly adopt small-scale irrigation and agroforestry. In terms of social groups, the Brahmin group was more likely to adopt new crop varieties and small-scale irrigation than the Sudra group. The Sudra farmers preferred temporary migration and off-farm activities more than the Brahmins.

For farmers, higher SOC levels have multiple benefits, including increased soil fertility and resilience against drought-related yield losses. However, increasing SOC levels requires agricultural management changes that are associated with costs. Private soil carbon certificates could compensate for these costs. In these schemes, farmers register their fields with commercial certificate providers who certify SOC increases. Certificates are then sold as voluntary emission offsets on the carbon market. In this paper, we assess the suitability of these certificates as an instrument for climate change mitigation. From a soils' perspective, we address processes of SOC enrichment, their potentials and limits, and options for cost-effective measurement and monitoring. From a farmers' perspective, we assess management options likely to increase SOC, and discuss their synergies and trade-offs with economic, environmental and social targets. From a governance perspective, we address requirements to guarantee additionality and permanence while preventing leakage effects. Furthermore, we address questions of legitimacy and accountability. While increasing SOC is a cornerstone for more sustainable cropping systems, private carbon certificates fall short of expectations for climate change mitigation as permanence of SOC sequestration cannot be guaranteed. Governance challenges include lack of long-term monitoring, problems to ensure additionality, problems to safeguard against leakage effects, and lack of long-term accountability if stored SOC is re-emitted. We conclude that soil-based private carbon certificates are unlikely to deliver the emission offset attributed to them and that their benefit for climate change mitigation is uncertain. Additional research is needed to develop standards for SOC change metrics and monitoring, and to better understand the impact of short term, non-permanent carbon removals on peaks in atmospheric greenhouse gas concentrations and on the probability of exceeding climatic tipping points.}, language = {en} } @article{DonmezSchmidtCileketal.2023, author = {Donmez, Cenk and Schmidt, Marcus and Cilek, Ahmet and Grosse, Meike and Paul, Carsten and Hierold, Wilfried and Helming, Katharina}, title = {Climate change impacts on long-term field experiments in Germany}, series = {Agricultural Systems}, journal = {Agricultural Systems}, number = {205}, publisher = {Elsevier}, doi = {10.1016/j.agsy.2022.103578}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8150}, pages = {17}, year = {2023}, abstract = {CONTEXT Long-Term Field Experiments (LTEs) were implemented to study the long-term effects of different management practices, including tillage, fertilization and crop rotation under otherwise constant conditions. Climate change is expected to change these conditions, challenging interpretation of LTE data with regard to the distinction between climate change and management effects. OBJECTIVE The objective of the study was to quantify the expected, spatially differentiated changes of agroclimatic conditions for the German LTE sites as a precondition for modelling and LTE data interpretation. METHODS We developed a framework combining spatially distributed climate data and LTE metadata to identify the possible climatic changes at 247 LTE sites with experiments running for 20 years or more. The LTEs were classified using the following categories: fertilization, tillage, crop rotation, field crops or grassland, conventional or organic. We utilized climate variables (temperature, precipitation) and agroclimatic indicators (aridity, growing degree days, etc.) to compare a baseline (1971-2000) with future periods (2021-2100) under the IPCC's Shared Socio-economic Pathways (SSP). A comprehensive LTE risk assessment was conducted, based on changes in climate variables and agroclimatic indicators between baseline and future scenarios. RESULTS AND CONCLUSIONS Under the most extreme scenario (SSP585), 150 LTEs are expected to shift from humid and dry sub-humid to semi-arid conditions. Frost days in LTE areas are expected to decline by 81\%, and the growing season to lengthen by up to 92\%. The spatial differentiation of expected climate change also facilitates the identification of suitable sites for future agricultural practices and may inform the design of new LTEs. SIGNIFICANCE Our results may guide the interpretation of LTE data regarding the effect of climate change, facilitating future soil crop modelling studies with LTE data and providing information for planning new LTE sites to support future agricultural research and/or adapting management on existing LTE sites. The framework we developed can easily be transferred to LTE sites in agricultural regions worldwide to support LTE research on climate change impacts and adaptation.}, language = {en} } @misc{TietzeGerholdIbisch2023, author = {Tietze, Nikola and Gerhold, Lars and Ibisch, Pierre L.}, title = {Policy narratives in forest fire management}, series = {Environmental Research Letters}, volume = {18}, journal = {Environmental Research Letters}, publisher = {IOP Publishing Ltd}, issn = {1748-9326}, doi = {10.1088/1748-9326/acf6d2}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8193}, pages = {32}, year = {2023}, abstract = {As the risk of forest fires increases around the globe, the issues of how to control, suppress, and prevent them are the subjects of growing public and political attention. This study focuses on the political debate in Germany regarding forest fires and provides insights into the conceptualization of forest fires and forest fire management at the federal and state policymaking levels. By examining forest fire narratives through the policy lens, this case study takes an exemplary extreme weather event exacerbated by climate change as an opportunity to examine the policy response to this problem. In this way, we examine the role of policy narratives in civil and environmental protection and disaster management. The findings reveal that all politicians examined in this study agree that forest fire management is an urgent matter that needs to be supported. In the prevailing human-centered narrative, policymakers see active forest management and use as tools to improve forest resilience to fire and other calamities. Those who advocate a nature-based narrative assert that it is natural processes in protected forest areas that most effectively enhance resilience. The policy solutions derived from these views include financial support, recognition of the work of foresters, forest fire managers, and civil protection agencies as well as, depending on the type of narrative argument favored, either increased forest management or improved protection of forest ecologies. This suggests that narrative analysis may illuminate the rationales underlying previous policy decisions and the framework for future ones. This contribution throws light on how narratives shape policymaking and, by extension, disaster management.

Two-year field trials data were collected from November 2018 to October 2020 in two experimental sites using a Randomized Complete Block Design (RCBD) with four replications. The results of analysis of variance over two years indicated that the effects of year, location, and year by location interaction were significant (p<0.01) for all of barley's yield components. Mixed cropping of barley with other species had no negative effect on barley traits such as grain yield, straw yield and harvest index. In addition, the mixed cropping of barley+ST and barley+ST+CZ in the first year produced 2.5 t/ha more forage yield than that mono-culture of barley. This was due to high production of Salsola (ST), in mixed cropping. In both years, yield of Salsola production was about 25\% of whole produced biomass. Drastic reduction in rainfall in the second year reduced the obtained yield; so, there was no significant difference among three cropping systems in the second year. However, cropping systems of barley+ST and barley+ST+CZ produced about 1 t/ha more forage than that for the mono-culture of barley.

The concept of providing services of general interest through social logistics and testing them in a real-world laboratory was based on preliminary work in the region. The results indicate that this approach can promote this type of social logistics in the long term. A social logistics approach does not focus solely on economic aspects but emphasises social and environmental benefits for the region. A real-world laboratory approach enables an environment that promotes open exchange, involvement of different stakeholders and joint problem solving in a reflective, iterative process.

Traditional manual measuring methods can be laborious, inaccurate and error-prone. Therefore, the issue is whether 2.5D or 3D optical remote sensing measuring methods provide more precise or detailed results and advantages in further data processing. This study examined and partly developed nine different manual, photo-optical, iPad®-LiDAR and handheld laser scanner-LiDAR-based wood stack measurement methods. Forty-seven wood stacks, ranging from 8.9 to 209.3 m3 (totalling approximately 2700 m3), were measured and compared using these nine methods. All the methods give volume estimations, and none can be seen to give the real or true wood stack gross volume. Surprisingly, the results varied significantly within and between the individual methods, with up to a 9\% mean relative deviation. The relative deviation is strongly dependent on the size of the wood stack. The 3D measurement methods using iPad® RGB and LiDAR recorded lower timber volumes than the other methods, in contrast to the method based on samples taken with handheld laser scanner-LiDAR, which overestimated the volume.

In scientific literature, the terms valorization and valuation are often used interchangeably. In addition, there is a lack of research on private options versus conventional, public policy options. Therefore, we searched for private valorization options primarily in public sources (gray literature and websites). This led to the identification of four clusters (markets for voluntary services, labeling, and certification, environmental management/CSR, and tradable permits and quotas). Based on these clusters the options were assessed from a legal and systems dynamics perspective. In addition, the viability of selected valorization options in different future scenarios was examined. The analysis revealed a wide range of private valorization options, which in contrast to public policy options that focus almost entirely on the production stage, are spread across the agri-food value chain.

Water is abstracted from rivers, which are largely fed by glacier melt. In the course of climate change, glaciers melt down so that a reduced glacier volume and reduced water runoffs are expected to be available for irrigation. Tree wind breaks are one option to reduce water consumption in irrigated agriculture and build resilience against climate change. This paper therefore assesses the water consumption of major crops in Kyrgyzstan and adjacent areas, i.e., cotton (Gossypium hirsutum L.), wheat (Triticum aestivum L.), corn (Zea mays L.), rice (Oryza sativa L.), potato (Solanum tuberosum L.), and barley (Hordeum vulgare L.) in combination with tree wind breaks. Crop water consumption was assessed through the Penman Monteith approach. Tree wind break types investigated were single rows from poplars (Populus spec.) and multiple rows with understory vegetation by elm (Ulmus minor L.) and poplar, respectively. Tree water consumption was determined through sapflow measurements. The seasonal reference evapotranspiration (ETo) for field crops was 876-995 mm without wind breaks and dropped to less than half through multiple row wind breaks with understory vegetation (50 m spacing). Tree water consumption was 1125-1558 mm for poplar and 435 mm for elm. Among the wind break crop systems, elm wind breaks resulted in the highest reductions of water consumption, followed by single row poplars, at spacing of 50 and 100 m, respectively. However, elm grows much slower than poplar, so poplars might be more attractive for farmers. Furthermore, single row wind breaks might by much easier to be integrated into the agrarian landscape as they consume less space.}, language = {en} } @article{HamidovDaedlowWebberetal.2022, author = {Hamidov, Ahmad and Daedlow, Katrin and Webber, Heidi and Hussein, Hussam and Abdurahmanov, Ilhom and Dolidudko, Aleksandr and Seerat, Ali Yawar and Solieva, Umida and Woldeyohanes, Tesfaye and Helming, Katharina}, title = {Operationalizing water-energy-food nexus research for sustainable development in social-ecological systems: an interdisciplinary learning case in Central Asia}, series = {Ecology \& Society}, volume = {27}, journal = {Ecology \& Society}, number = {1}, publisher = {Resilience Alliance}, issn = {1708-3087}, doi = {10.5751/ES-12891-270112}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6890}, pages = {17}, year = {2022}, abstract = {In social-ecological systems, natural resource management can be characterized by trade-offs across sectors and sustainability targets.

Results within this process highlight that water governance was critical for large-scale transboundary WEF nexus management, while land and soil management were decisive for minimizing trade-offs at local levels. Issues of interdisciplinarity, complexity, uncertainty, and reflection on impacts were adequately addressed, but challenges remain in the consideration of ethics and the design of transparent, multi-actor cooperation.

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.

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} } @article{MacPhersonVoglhuberSlavinskyOlbrischetal.2022, author = {MacPherson, Joseph and Voglhuber-Slavinsky, Ariane and Olbrisch, Mathias and Sch{\"o}bel, Philipp and D{\"o}nitz, Ewa and Mouratiadou, Ioanna and Helming, Katharina}, title = {Future agricultural systems and the role of digitalization for achieving sustainability goals.

Therefore, the recognition of these indicators on a spatial level is a prerequisite for monitoring grassland biodiversity. The identification of indicator species for the status quo of grassland using traditional methods was found to be challenging and tedious. Deep learning-algorithms applied to high-resolution UAV imagery could be the key solution, where UAV with remote sensors can map a large area of grassland in comparison to manual or ground mapping methods and deep learning-algorithms can automate the detection process. In this research work, we use an EfficientDet based algorithm to train an object detection model capable of recognizing indicators on RGB data.

Also, results demonstrated that with DBT greater than 20 mm, the percentage of Vbark exceeded 20\%.

This study investigated the physicochemical characteristics of mixed sawdust generated from five wood species generated at a Ghanaian sawmill in Oforikrom Municipality for improving waste treatment. The particle size distribution (PSD), bulk density, proximate and ultimate values, thermogravimetric analysis (TGA) and structural analysis were used to characterize the composite sawdust for briquetting and gasification purposes. It was found that the net heating value (17.46 MJ/kg), some proximate and ultimate values meet briquette standard but high percentages of ash (2.95\%), moisture (41.48\%) and the possibility of nitrogen oxides emissions were notable challenges. PSD resulted in different high fine fractions which are unsuitable for densification. The increase of sieving amplitudes at 30, 50 and 80 rpm generated an average increase in sieve efficiency of fines by 4.22\%. Mixing of fines (42.38-46.6\%) and optimum particle size (53.40-57.62\%) fractions was suggested as the best approach to enhance briquette density and durability. The FTIR spectra showed a range of peaks such as 1734.46 cm-1, 1620.48 cm-1, 1506.50 cm-1, 1462.02 cm-1, 1420.32 cm-1 etc. for functional groups identification. Composite sawdust spectra showed high absorbance with no shift of wavenumbers compared with temperate woods, however, it deviated massively when compared with industrial cellulose and organosolv lignin. TGA indicated that exact mixed wood pyrolysis temperatures, volatile and biochar fractions will always depend on sample compositions. The increase in heating rates yielded little significance to volatiles and char increments. Collection of clean sawdust and rooftop drying were recommended as a way of enhancing sawdust properties.

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.

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.

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.

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} }
