In Germany, the quality of these grasslands is assessed based on the occurrence of certain plant species known as indicator or character species, with indicators being defined at regional level. 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. The experimental results show that this approach is very promising in contrast to the difficult and time-consuming manual recognition methods. The model was trained with the momentum-SGD optimizer with a momentum value of 0.9 and a learning rate of 0.0001. The model was trained and tested on 1200 images and achieves 45.7 AP (and 85.7 AP50) on test data set. The dataset includes images of four distinct indicator plant species: Armeria maritima, Campanula patula, Cirsium oleraceum, and Daucus carota}, language = {en} } @misc{WelleIbischBlumroederetal.2021, author = {Welle, Torsten and Ibisch, Pierre L. and Blumr{\"o}der, Jeanette Silvin and Bohr, Yvonne E.-M.

Im Beitrag wird eine {\"U}bersicht {\"u}ber etwaige Auswirkungen des Verbots auf die verschiedenen Akteure der Wertsch{\"o}pfungskette gegeben. Ferner wird der aktuelle Stand bei den Alternativen zum K{\"u}kent{\"o}ten beleuchtet. Große international t{\"a}tige Zuchtunternehmen wie Lohmann haben in ihren Br{\"u}tereien Anlagen zur Geschlechtsbestimmung im Ei installiert (seit 2022 auch in Deutschland). Ferner bieten sie ihren Kunden alternativ die Bruderhahnaufzucht oder auch Zweinutzungsherk{\"u}nfte an. Die Zahl der Br{\"u}tereien mit Legek{\"u}ken (zum Gebrauch) hat von 2021 auf 2022 abgenommen (von 22 auf 14). Da die Gesamtzahl aller Br{\"u}tereien aber nur von 54 auf 51 zur{\"u}ckging, haben offensichtlich einige auf andere Gefl{\"u}gelarten umgestellt. Die Zahl der geschl{\"u}pften Legek{\"u}ken nahm stark ab (2020 40,5 Mio., 2022 16,2 Mio., 1. Halbjahr 2023 9,9 Mio.). Es besteht ein Bedarf von 47 - 63 Millionen Junghennen im Jahr (bei 12 - 15 Monaten Nutzungsdauer). Mit den f{\"u}r 2020 angegebenen 12,2 Millionen Pl{\"a}tzen konnten nur etwa 28 Millionen Junghennen erzeugt werden, woran der Importbedarf deutlich wird. Der gr{\"o}ßte Teil der importierten Legek{\"u}ken (f{\"u}r Aufzuchtbetriebe) oder Junghennen (f{\"u}r Legehennenbetriebe) kommt allerdings aus Erzeugung ohne K{\"u}kent{\"o}ten. Denn von 50 Millionen Haltungspl{\"a}tzen mit alternativen Haltungssystemen in Deutschland werden 86 Prozent vom Verein KAT kontrolliert, der das K{\"u}kent{\"o}ten auch bei Importen ausschließt. Die Haltung von Legehennen stieg im Jahr 2022 weiter an (Anzahl Betriebe + 6 \%, Haltungspl{\"a}tze + 3 \%, Legehennen + 2 \%). Auf eine verl{\"a}ngerte Nutzungsdauer der Hennen deuten sinkende Schlachtzahlen f{\"u}r Althennen in Deutschland hin (2021 34,0 Mio., 2022 29,7 Mio.). Die großen Einzelhandelsketten haben sich verpflichtet, nur noch Schaleneier ohne K{\"u}kent{\"o}ten (OKT) anzubieten, auch f{\"u}r importierte Eier. Einige Ketten dehnen das schrittweise auch auf Eier in verarbeiteten Produkten aus. Traditionell werden etwa 30 Prozent aller Eier in Deutschland importiert. Die Verbraucherpreise stiegen bereits 2021 aufgrund des K{\"u}kent{\"o}tungsverbots etwas an, 2022 hingegen Inflationsbedingt stark. Dennoch ist der Konsum von Eiern nur leicht zur{\"u}ckgegangen (von 233 in 2021 auf 230 in 2022). Beim Kauf von Schaleneiern gab es in 2022 eine leichte Verschiebung zu kosteng{\"u}nstigeren Eiern (Bio-Eier - 1,2 \%), sowie zu K{\"a}ufen im Discounter (+ 2 \%). Verbraucherstudien haben gezeigt, dass mittlerweile die meisten Konsumenten die Problematik des K{\"u}kent{\"o}tens kennen und dieses auch ablehnen. Die Alternativen dazu sind jedoch weniger bekannt. Dies trifft am meisten auf Zweinutzungsh{\"u}hner zu. Bei der Geschlechtsbestimmung im Ei hat eine starke Weiterentwicklung stattgefunden. Mittlerweile sind Anlagen mit f{\"u}nf verschiedenen Verfahren in Br{\"u}tereien im Einsatz (seit 2022 auch in Deutschland). Die f{\"u}r Deutschland angegebenen Kapazit{\"a}ten addieren sich auf etwa 17 - 21 Millionen Eiern im Jahr. Die derzeit in den Br{\"u}tereien genutzten Verfahren k{\"o}nnen nach der Gesetzes{\"a}nderung (Bestimmung bis max. 12. Bruttag) k{\"u}nftig weiter angewendet werden. Aus Tierschutzsicht w{\"a}re allerdings eine Bet{\"a}ubung der Embryonen vor der T{\"o}tung zu diskutieren. Die Anzahl Br{\"u}tereien mit Sortierung von Bruderh{\"a}hnen hat deutlich zugenommen (2021 4, 2022 13). 2022 wurden 10,59 Millionen m{\"a}nnliche K{\"u}ken zur Aufzucht aussortiert. Dies macht einen Anteil von 65,3 Prozent der 16,20 Millionen geschl{\"u}pften Legek{\"u}ken aus ({\"U}brige Geschlechtsbestimmung). Mit den von der Branche angegebenen 5 - 8 Millionen Pl{\"a}tzen ließen sich 20 - 23 Millionen Bruderh{\"a}hne im Jahr aufziehen. Die KAT gibt an, dass 2022 9 von 20 Millionen Bruderh{\"a}hnen in Polen aufgezogen wurden. {\"U}ber die Verwendung der Bruderh{\"a}hne ist wenig bekannt. KAT schreibt eine Verwendung als Lebensmittel vor. Zweinutzungsh{\"u}hner sind bislang noch selten in der Praxis anzutreffen (gesch{\"a}tzt unter 1 \% der Hennen). Sie sind bei vielen Verbrauchern nicht bekannt und in den Superm{\"a}rkten gibt es keine speziellen Angebote.

Valorization incentivizes measures for promoting BES, while valuation refers to its quantification. Valuation can be a step of valorization but is not indispensable. 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.

The use of digital technologies can support this by designing and managing resource-efficient and context-specific agricultural systems. We present the Digital Agricultural Knowledge and Information System (DAKIS) to demonstrate an approach that employs digital technologies to enable decision-making towards diversified and sustainable agriculture. To develop the DAKIS, we specified, together with stakeholders, requirements for a knowledge-based decision-support tool and reviewed the literature to identify limitations in the current generation of tools. The results of the review point towards recurring challenges regarding the consideration of ecosystem services and biodiversity, the capacity to foster communication and cooperation between farmers and other actors, and the ability to link multiple spatiotemporal scales and sustainability levels. To overcome these challenges, the DAKIS provides a digital platform to support farmers' decision-making on land use and management via an integrative spatiotemporally explicit approach that analyses a wide range of data from various sources. The approach integrates remote and in situ sensors, artificial intelligence, modelling, stakeholder-stated demand for biodiversity and ecosystem services, and participatory sustainability impact assessment to address the diverse drivers affecting agricultural land use and management design, including natural and agronomic factors, economic and policy considerations, and socio-cultural preferences and settings. Ultimately, the DAKIS embeds the consideration of ecosystem services, biodiversity, and sustainability into farmers' decision-making and enables learning and progress towards site-adapted small-scale multifunctional and diversified agriculture while simultaneously supporting farmers' objectives and societal demands.}, language = {en} } @article{PurfuerstdeMiguelDiezBerendtetal.2023, author = {Purf{\"u}rst, Thomas and de Miguel-D{\´i}ez, Felipe and Berendt, Ferr{\´e}ol and Engler, Benjamin and Cremer, Tobias}, title = {Comparison of wood stack volume determination between manual, photo-optical, iPad-LiDAR and handheld-LiDAR based measurement methods}, series = {iForest - Biogeosciences and Forestry}, volume = {16}, journal = {iForest - Biogeosciences and Forestry}, number = {4}, publisher = {Italian Society of Silviculture and Forest Ecology}, issn = {1971-7458}, doi = {10.3832/ifor4153-016}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8062}, pages = {243 -- 252}, year = {2023}, abstract = {The measurement of roadside wood stacks in the forest still plays an important role in many forestry operations. 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. Generally, optical- and laser-based surveying techniques could be more widely applied in measuring wood stacks in the future. However, such automatic wood stack gross volume determination approaches still face some challenges, regarding accuracy in the case of the 2.5D methods and the lack of automatisation in the case of 3D methods.

As part of a real-life laboratory, two services were developed and tested with the aim of improving rural supply: the delivery of regional goods and the return of online orders in cooperation with a regional public transport provider, regional retailers and parcel services. An evaluation team provided support to the project in identifying, monitoring, and documenting the societal impact of the services and promoted impact-oriented project management. 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. This methodological approach enabled the continuation and out-scaling of the service's core offerings immediately after ending the test phase and is seen as an important prerequisite for establishing a long-term perspective.}, language = {en} } @article{ArrekhiNiknahadGharmakherBachingeretal.2022, author = {Arrekhi, Armin and Niknahad Gharmakher, Hamid and Bachinger, Johann and Bloch, Ralf}, title = {Investigation of Feasibility and Effect of Alternative Farming System on the Grain Yield of Barley and Forage Production in Western Semi-arid Region of Golestan Province, Iran}, series = {Journal of Rangeland Science}, volume = {13}, journal = {Journal of Rangeland Science}, number = {2}, publisher = {IA University, Borujerd Branch}, issn = {2008-9996}, doi = {10.30495/rs.2023.688855}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8022}, pages = {155 -- 167}, year = {2022}, abstract = {One of the major challenges in semi-arid regions of Iran is to supply the adequate forage for livestock and meanwhile prevent the destruction of rangelands due to overgrazing. Therefore, this study aimed to compare three cropping systems of barley using Salsola turcomanica (ST), and Chrysopogon zizanioides (CZ) in three treatments of barley+ST, barley+ST+CZ and mono-culture of barley. 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. Mixed cropping of barley +ST+CZ did not affect yield components of barley. Mixed cropping of barley with Salsola turcomanica could guarantee soil cover throughout the year and is recommended for forage production in rangeland in Iran.}, language = {en} } @article{RecklingWatsonWhitbreadetal.2023, author = {Reckling, Moritz and Watson, Christine A. and Whitbread, Anthony and Helming, Katharina}, title = {Diversification for sustainable and resilient agricultural landscape systems}, series = {Agronomy for Sustainable Development}, volume = {43}, journal = {Agronomy for Sustainable Development}, publisher = {Springer Nature}, issn = {1773-0155}, doi = {10.1007/s13593-023-00898-5}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8135}, pages = {5}, year = {2023}, abstract = {This virtual issue comprises papers that address diversification for providing sustainable solutions at different scales from cropping and grassland to food systems. The authors investigated processes in case studies at the landscape scale where synergies and trade-offs between social and environmental objectives become the most tangible. Contributions from all continents highlighted regional specificities related to diversification and include research from natural and social sciences, with inter- and transdisciplinary approaches including synthesis of knowledge (reviews), empirical studies with experiments as well as assessments with interviews in case studies: Model-based design of crop diversification, the role of digitalization for achieving sustainability in the European context, ecological engineering for rice pest suppression in China, the role of cereal species mixtures in Ethiopian smallholder farmers, diversified planting in arid irrigation areas in northwestern China, integration of legumes in European and Canadian cropping systems, screening of native forage legumes for northern Swedish grassland systems, cropping system diversification of smallholder farmers in south-central Bangladesh, identification of how farmers imagine diversified landscapes in southern Idaho in the US, farm diversification affecting impacts from COVID-19 across Europe, the role of diversified farming in Mato Grosso Brazil, diversification and soil management measures in Germany, value chain formation for the scaling of crop diversification, and the design process with farmers and scientists for the transition toward legume-supported farming in Europe. A key finding from these examples is that agricultural intensification has led to the simplification of cropping systems and landscapes in terms of species diversity and ecosystem function. To instead move towards sustainable transformation, all system levels (i.e. from the plot, farm, landscape, governance and overall food systems) need to interact and reinforce each other for diversification to deliver the desired outcomes.}, language = {en} } @article{LauterbachBrunsHaering2023, author = {Lauterbach, Josephine and Bruns, Antonia Johanna and H{\"a}ring, Anna Maria}, title = {Exploring Consumer Preference towards the On-Farm Slaughtering of Beef in Germany: A Discrete Choice Experiment}, series = {Foods}, journal = {Foods}, number = {12}, publisher = {MDPI}, issn = {2304-8158}, doi = {10.3390/foods12183473}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-7753}, pages = {15}, year = {2023}, abstract = {Current production standards and communication campaigns about animal welfare in relation to beef strongly emphasise the "humane" rearing of cattle.

On-farm slaughter can address these criticisms. Communicating the value of low-stress slaughtering conditions like on-farm slaughtering may offer significant sales potential for a premium market segment. In this study, we explore consumers' preferences and willingness to pay for beef that is slaughtered on-farm rather than in conventional abattoirs.

Our survey included a discrete choice experiment for the purchase of minced beef, incorporating product attributes that influence purchase decisions. These included: price, information on the social, economic and environmental benefits of regional production, different production standards (conventional/organic) and information on on-farm slaughtering. Our findings indicate that consumers derive the highest utility from a low price, followed by information about on-farm slaughtering.

An analysis of how different types of multi-actor co-innovation partnerships function can help to identify the reasons why some are more successful than others in 'speeding up' innovation. OBJECTIVE To provide a framework for the analysis of the co-innovation process, we developed a multidimensional conceptual typology of co-innovation activities based on a review of 200 such partnerships involving farmers and foresters from across Europe. This framework is based on innovation systems theory and the prevailing policy context of the 'multi-actor approach'. METHODS The overarching concept or dependent variable measured by the typology is 'effectiveness of co-innovation by a multi-actor partnership' and the two dimensions of the overarching concept are the 'structural components of the Organisational Innovation System', with four categories, and 'attitude towards interaction', with two categories. The result is a matrix of eight 'ideal types' of co-innovation activity. These eight types are characterised according to first-order constructs derived from our research data. RESULTS AND CONCLUSIONS The results show that the co-innovation process can successfully take contrasting forms according to the 'contextual contingencies' encountered by the partnership. In other words, no one ideal type is intrinsically 'superior' to another but may be more 'appropriate' in given circumstances. Factors influencing approaches to implementation include actor capacities, aspirations and networks, the co-innovation topic and its influence on the partnership size and the workplan structure, the type of co-innovation activity outputs and the need to engage with the 'larger periphery' of stakeholders, and the nature of the enabling environment. SIGNIFICANCE The typology is not a classification since the ideal types represent organisational forms that might exist rather than real partnerships. However, the analytical framework it provides will help policy makers and programme managers to develop targeted interventions, according to actor needs and local circumstances, for 'speeding up' innovation.}, language = {en} } @article{BarthJimenezAceitunoPMLametal.2023, author = {Barth, Matthias and Jim{\´e}nez-Aceituno, Amanda and PM Lam, David and B{\"u}rgener, Lina and J Lang, Daniel}, title = {Transdisciplinary learning as a key leverage for sustainability transformations}, series = {Current Opinion in Environmental Sustainability}, volume = {64}, journal = {Current Opinion in Environmental Sustainability}, publisher = {Elsevier}, issn = {1877-3435}, doi = {10.1016/j.cosust.2023.101361}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6483}, pages = {8}, year = {2023}, abstract = {Learning and transdisciplinary research are widely acknowledged as key components for achieving sustainability; however, the links between these concepts remain vague in the sustainability literature. Recently, emphasis has been given to transdisciplinary learning, highlighting its potential as an approach that contributes to solving real-world problems. To better understand and foster transdisciplinary learning for sustainability transformations, it is relevant to pay attention to two dimensions that define transdisciplinary learning: social interaction (individual learning in a social setting, as a group, or beyond the group), and learning forms (single-, double-, or triple-loop learning). This article introduces a conceptual framework built upon these two dimensions to understand three specific forms of transdisciplinary learning as a) individual competence development, b) experience-based collaboration, and c) societal interaction. This framework helps to clarify the design of learning processes as well as their interactions in transdisciplinary processes to support transformative change.}, language = {en} } @article{WeissvonWehrdenLinde2023, author = {Weiss, Fabio and von Wehrden, Henrik and Linde, Andreas}, title = {Random year intercepts in mixed models help to assess uncertainties in insect population trends}, series = {Insect Conservation and Diversity}, volume = {16}, journal = {Insect Conservation and Diversity}, number = {4}, publisher = {Wiley}, issn = {1752-4598}, doi = {10.1111/icad.12644}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6496}, pages = {531 -- 537}, year = {2023}, abstract = {1. An increasing number of studies is investigating insect population trends based on time series data. However, the available data is often subject to temporal pseudoreplication. Inter-annual variability of environmental conditions and strong fluctuations in insect abundances can impede reliable trend estimation. Temporal random effect structures in regression models have been proposed as solution for this issue, but remain controversial. 2. We investigated trends in ground beetle abundance across 24 years using generalised linear mixed models. We fitted four models: A base model, a model featuring a random year intercept, a model featuring basic weather parameters, and a model featuring both random year intercept and weather parameters. We then performed a simple sensitivity analysis to assess the robustness of the four models with respect to influential years, also testing for possible spurious baseline and snapshot effects. 3. The model structure had a significant impact on the overall magnitude of the estimated trends. However, we found almost no difference among the models in how the removal of single years (sensitivity analysis) relatively affected trend coefficients. The two models with a random year intercept yielded significantly larger confidence intervals and their p-values were more sensitive during sensitivity analysis. Significant differences of the model with random year intercept and weather parameters to all other models suggest that the random year effects and specific weather effects are rather additive than interchangeable. 4. We conclude that random year intercepts help to produce more reliable and cautious uncertainty measures for insect population trends. Moreover, they might help to identify influential years in sensitivity analyses more easily. We recommend random year intercepts in addition to any variables representing temporally variable environmental conditions, such as weather variables.}, language = {en} } @article{SteckeldelRioHeymetal.2020, author = {Steckel, M. and del R{\´i}o, M. and Heym, M. and Aldea, J. and Bielak, K. and Brazaitis, G. and Čern{\´y}, J. and Coll, L. and Collet, C. and Ehbrecht, M. and Jansons, A. and Nothdurft, A. and Pach, M. and Pardos, M. and Ponette, Q. and Reventlow, D.O.J. and Sitko, R. and Svoboda, M. and Vallet, P. and Wolff, B. and Pretzsch, H.}, title = {Species mixing reduces drought susceptibility of Scots pine (Pinus sylvestris L.) and oak (Quercus robur L., Quercus petraea (Matt.)

However, so far only a limited number of species combinations have been studied in detail, revealing inconsistent results. In this study, we analysed the effect of mixing Scots pine and oak (pedunculate oak and sessile oak) trees on their drought response along a comprehensive ecological gradient across Europe. The objective was to improve our knowledge of general drought response patterns of two fundamental European tree species in mixed versus monospecific stands. We focused on three null hypotheses: () tree drought response does not differ between Scots pine and oak, () tree drought response of Scots pine and oak is not affected by stand composition (mixture versus monoculture) and () tree drought response of Scots pine and oak in mixtures and monocultures is not modified by tree size or site conditions. To test the hypotheses, we analysed increment cores of Scots pine and oak, sampled in mixed and monospecific stands, covering a wide range of site conditions. We investigated resistance (the ability to maintain growth levels during drought), recovery (the ability to restore a level of growth after drought) and resilience (the capacity to recover to pre-drought growth levels), involving site-specific drought events that occurred between 1976 and 2015. In monocultures, oak showed a higher resistance and resilience than Scots pine, while recovery was lower. Scots pine in mixed stands exhibited a higher resistance, but also a lower recovery compared with Scots pine in monocultures. Mixing increased the resistance and resilience of oak. Ecological factors such as tree size, site water supply and site fertility were found to have significant effects on the drought response. In the case of Scots pine, resistance was increased by tree size, while recovery was lowered. Resistance of oak increased with site water supply. The observed mixing effect on the tree drought response of Scots pine and oak was in some cases modified by the site conditions studied. Positive mixing effects in terms of resistance and resilience of oak increased with site water supply, while the opposite was found regarding recovery. In contrast, site fertility lessened the positive mixing effect on the resistance of Scots pine. We hypothesise that the observed positive mixing effects under drought mainly result from water- and/or light-related species interactions that improve resource availability and uptake according to temporal and spatial variations in environmental conditions.}, language = {en} }
