To fill this gap, this study aimed to identify the effect of agro-ecological zones and social groups on smallholder farmers' adaptation to climate change using the multivariate probit model. Multistage sampling was used to collect data from 400 households in three agro-ecological zones of Nepal. These zones were highland (mountainous region), midland (hilly region) and lowland (terai/plain region). 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. Our study shows that policies to promote the adoption of CCA strategies need to take into account location and social group differences in order to improve the adaptive capacity of the most vulnerable farmers.

The objective of this study was to determine the pesticide handling behaviour and the effectiveness of pesticide information on pesticide handling knowledge and personal protective equipment (PPE) use among farmers in southwest Nigeria. One hundred and fifty-six farmers were interviewed using a structured questionnaire in December 2019 and January 2020. The results revealed that a one-third of the farmers dispose their pesticide residues on the field, only 3\% of the farmers dispose the hazardous pesticide waste at a collection point, and 65\% of them dispose the empty containers indiscriminately. 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.

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. Future studies should therefore take into account the influence of prevailing narratives when it comes to evaluating the potential that policymaking can offer for disaster management in the future.}, language = {en} } @article{Ibisch2023, author = {Ibisch, Pierre L.}, title = {Nat{\"u}rlicher Klimaschutz als strategische {\"O}kosystementwicklungsplanung Land und Raum in der Multikrise}, series = {Politische {\"O}kologie}, volume = {172}, journal = {Politische {\"O}kologie}, number = {1}, publisher = {oekom Verlag}, issn = {2625-543X}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8187}, pages = {119 -- 123}, year = {2023}, language = {de} } @techreport{Hoerning2023, author = {H{\"o}rning, Bernhard}, title = {Zur Umsetzung des K{\"u}kent{\"o}tungsverbots in Deutschland}, series = {Berichte {\"u}ber Landwirtschaft - Zeitschrift f{\"u}r Agrarpolitik und Landwirtschaft}, volume = {101}, journal = {Berichte {\"u}ber Landwirtschaft - Zeitschrift f{\"u}r Agrarpolitik und Landwirtschaft}, number = {3}, editor = {Bundesministerium f{\"u}r Ern{\"a}hrung und Landwirtschaft (BMEL),}, issn = {2196-5099}, doi = {10.12767/buel.v101i3.495}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8178}, pages = {61}, year = {2023}, abstract = {Seit Anfang 2022 ist das T{\"o}ten der m{\"a}nnlichen Eintagsk{\"u}ken der Legelinien in Deutschland verboten.

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.

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).

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} } @article{PaulBartkowskiDoenmezetal.2023, author = {Paul, Carsten and Bartkowski, Bartosz and D{\"o}nmez, Cenk and Don, Axel and Mayer, Stefanie and Steffens, Markus and Weigl, Sebastian and Wiesmeier, Martin and Wolf, Andr{\´e} and Helming, Katharina}, title = {Carbon farming: Are soil carbon certificates a suitable tool for climate change mitigation?}, series = {Journal of Environmental Management}, journal = {Journal of Environmental Management}, number = {330}, publisher = {Elsevier}, issn = {0301-4797}, doi = {10.1016/j.jenvman.2022.117142}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8140}, pages = {11}, year = {2023}, abstract = {Increasing soil organic carbon (SOC) stocks in agricultural soils removes carbon dioxide from the atmosphere and contributes towards achieving carbon neutrality. 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{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.

Efforts for private and public governance are increasingly emerging to leverage sustainable soil management. They require consensus across science, policy, and practice about what sustainable soil management entails. Such agreement does not yet exist to a sufficient extent in agronomic terms; what is lacking is a concise list of soil management measures that enjoy broad support among all stakeholders, and evidence on the question what hampers their implementation by farmers. We therefore screened stakeholder documents from public governance institutions, nongovernmental organizations, the agricultural industry, and conventional and organic farmer associations for recommendations related to agricultural soil management in Germany. Out of 46 recommended measures in total, we compiled a shortlist of the seven most consensual ones: (1) structural landscape elements, (2) organic fertilization, (3) diversified crop rotation, (4) permanent soil cover, (5) conservation tillage, (6) reduced soil loads, and (7) optimized timing of wheeling. Together, these measures support all agricultural soil functions, and address all major soil threats except soil contamination. Implementation barriers were identified with the aid of an online survey among farmers (n = 78). Results showed that a vast majority of farmers (> 80\%) approved of all measures. Barriers were mostly considered to be economic and in some cases technological, while missing knowledge or other factors were less relevant. Barriers were stronger for those measures that cannot be implemented in isolation, but require a systemic diversification of the production system. This is especially the case for measures that are simultaneously beneficial to many soil functions (measures 2, 3, and 4). Results confirm the need for a diversification of the agricultural system in order to meet challenges of food security and climate change.

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.

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.

Es beinhaltet den Versuch einer Absch{\"a}tzung der Deckungsl{\"u}cke bzw. des regional{\"o}konomischen Risikos f{\"u}r den Landkreis Uckermark - einer l{\"a}ndlich gepr{\"a}gten, peripheren, wirtschaftlich eher schwachen Region im Bundesland Brandenburg. Es wird gezeigt, wie Sch{\"a}tzans{\"a}tze zu Bedarfen und Potenzialen im Bereich der Unternehmensnachfolge auf die Uckermark angewendet werden k{\"o}nnen, welche Resultate dies ergibt und wie belastbar diese sind. Es zeigt sich, dass bis 2025 ca. 1.150 Unternehmen in der Uckermark vor einer Nachfolge stehen. Mit einer gewissen Wahrscheinlichkeit werden 138 bis 322 Unternehmen den Nachfolgeprozess nicht {\"u}berstehen. Hiernach kann eine Aussage zum regional{\"o}konomischen Risiko getroffen werden. Da diese Betrachtung eher einem Status-Quo Szenario folgt, beinhaltet das Monitoring auch eine Diskussion dazu, inwiefern Megatrends wie New Work oder auch Neo-{\"O}kologie Potenziale f{\"u}r eine Reduktion der Deckungsl{\"u}cke und damit des regional{\"o}konomischen Risikos besitzen. Schließlich reflektiert das Monitoring die angewendeten (und angepassten) Methodiken und stellt heraus, wie mit Problemen der vorgenommenen Regionalisierung umgegangen werden k{\"o}nnte. Dies liefert eine Basis f{\"u}r ein vertieftes und hiernach belastbareres regionales Nachfolgemonitoring.}, language = {de} } @techreport{Conrad2023, author = {Conrad, Alexander}, title = {Evaluation des Instruments Raumstipendium - Bewertung der Zielerreichung und Wirkung nach einem Jahr Anwendung}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8072}, pages = {92}, year = {2023}, abstract = {Das Raumstipendium ist ein Instrument der Zwischennutzung des Haus mit Zukunft in Angerm{\"u}nde (Uckermark). Es wurde 2022 das erste Mal eingesetzt und hat 16 Raumstipendiat:innen Raum und Ort f{\"u}r das Entwickeln und Umsetzen von Angeboten und Leistungen gegeben. Dabei waren mit dem Raumstipendium verschiedene Zielsetzungen verbunden: {\"U}bergeordnete Ziele, wie die sinnvolle Zwischennutzung einer st{\"a}dtischen Immobilie, aber auch das positive Einwirken in die st{\"a}dtische Entwicklung oder die F{\"o}rderung des Gemeinwohls. Daneben hatten die 16 Stipendiat:innen selbst Ziele, die z.B. das Schaffen eines Raums f{\"u}r freies Experimentieren und Gestalten, das Stiften von Freude und Spaß, der Austausch und die Identifikation mit Gleichgesinnten oder aber auch die F{\"o}rderung der Selbstwirksamkeit der Menschen in der Stadt umfassten. Nach einem Jahr Laufzeit sollte ermittelt werden, ob die Ziele, die mit dem Instrument verbunden waren, erreicht wurden und es sollten Wirkungen des Instruments ermittelt werden. Hierzu wurde eine Evaluation durchgef{\"u}hrt, die auf Befragung der f{\"u}r das Raumstipendium verantwortlichen Akteur:innen und der Raumstipendiat:innen fußt. Die Evaluation ist im Kern als summative Evaluation angelegt, sie besetzt aber auch formative Elemente. Ergebnis ist, dass die mit dem Raumstipendium verbundenen Ziele sehr gut erreicht werden konnten. Außerdem gibt es vielf{\"a}ltige Anhaltspunkte daf{\"u}r, dass das Instrument konkrete Wirkungen erzielt hat: So lassen sich Indizien daf{\"u}r finden, dass in der Stadt neues Wissen entstanden ist, dass sich Verhaltensweisen ge{\"a}ndert haben und das sich auch die individuellen Lebensumst{\"a}nde z.B. der Raumstipendiat:innen, aber auch der Nutzer:innen ihrer Angebote verbessert haben.

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{MouratiadouLemkeChenetal.2023, author = {Mouratiadou, Ioanna and Lemke, Nahleen and Chen, Cheng and Wartenberg, Ariani and Bloch, Ralf and Donat, Marco and Gaiser, Thomas and Hanike Basavegowda, Deepak and Helming, Katharina and Ali Hosseini Yekani, Seyed and Krull, Marcos and Lingemann, Kai and Macpherson, Joseph and Melzer, Marvin and Nendel, Claas and Piorr, Annette and Shaaban, Mostafa and Zander, Peter and Weltzien, Cornelia and Bellingrath-Kimura, Sonoko Dorothea}, title = {The Digital Agricultural Knowledge and Information System (DAKIS): Employing digitalisation to encourage diversified and multifunctional agricultural systems}, series = {Environmental Science and Ecotechnology}, volume = {16}, journal = {Environmental Science and Ecotechnology}, publisher = {Elsevier}, issn = {2666-4984}, doi = {10.1016/j.ese.2023.100274}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-8012}, pages = {13}, year = {2023}, abstract = {Multifunctional and diversified agriculture can address diverging pressures and demands by simultaneously enhancing productivity, biodiversity, and the provision of ecosystem services. 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} }
