Agroecology is often considered as the ultimate and most comprehensive solution to many challenges of agricultural food system, also referred agri-food system. This review investigates what extent agroecology can become mainstream model for transforming agriculture toward more sustainable resilient systems within given economic political context. We find that enhancing will require a fully integrated multiscale approach from farm region globe. The must consider relevant processes relationships, actors stakeholders well drivers, sustainability indicators, respective assessment methods across all scales. Giving specific attention drivers related economy, technology, policy we point out needs be economically viable farmers other system actors. In particular, new emerging technologies digitalization breeding should consideration in agroecological transformation. stress need an analytical operational framework adequate design suggest six areas needed support large-scale adoption agroecology.

Abstract Digitalisation is rapidly transforming the agri-food sector. This paper investigates emerging opportunities, challenges and policy options. We show that digital innovations can contribute to more sustainable resilient agricultural systems. For example, enable increased productivity, reduced environmental footprints higher resilience of farms. However, these optimistic outcomes increasing digitalisation sector will not emerge on their own, but this development comes with several challenges, costs risks, e.g. in economic, social ethical dimensions. provide recommendations explore opportunities avoid risks. Moreover, we discuss implications for future research economics.

Key research challenges to supporting farm transitions to agroecology in advanced economies. A review

Agronomy for Sustainable Development, Год журнала: 2023, Номер 43(1)

Опубликована: Янв. 10, 2023

Abstract In response to the sustainability issues that agriculture faces in advanced economies, agroecology has gained increasing relevance scientific, political, and social debates. This promoted discussion about transitions agroecology, which represents a significant advancement. Accordingly, it become growing field of research. We reviewed literature on support farm economies order identify key research challenges suggest innovative paths. Our findings can be summarized as follows: (1) Research supports exploration definition desired futures, whether based future-oriented modeling or expert-based foresight approaches, should more explicitly include level. It stimulate creativity design ability farmers other stakeholders, also address representation power among them. (2) creates awareness assesses farms before, during after transition requires holistic dynamic assessment frameworks. These frameworks need flexible adapt diversity global local challenges. Their uncertainty due feedback loops emergent properties transitions. (3) analyzes focus dynamics change processes by valuing what happens farms. especially give credence on-farm experiments conducted develop new tools methods (e.g., for strategic monitoring) these is first review scientific studies agroecology. Overall, indicates challenge system boundaries, temporal horizons, dimensions agricultural researchers usually consider. this context, require changes current organization funding encourage longer term adaptive configurations.

The adoption of pesticide-free wheat production and farmers' perceptions of its environmental and health effects

Ecological Economics, Год журнала: 2022, Номер 198, С. 107463 - 107463

Опубликована: Май 9, 2022

The reduction of pesticide use is a prime issue on policy agendas worldwide. However, existing policies often fail to promote widespread adoption low-pesticide or no-pesticide production practices. Therefore, in order overcome this obstacle, it important understand why farmers hesitate more sustainable pest management. To end, we investigate the relationship between farmers' perception adverse environmental and human health effects generated by pesticides their decision participate novel, pesticide-free wheat standard Switzerland. Survey data from 1073 producers reveals that 14% are early adopters program further 44% intend switch scheme following growing seasons. We find who perceive risks for environment be higher also likely adopt production. Our results suggest large-scale requires broad set (policy) instruments beyond purely financial incentives. findings thus have implications design schemes.

Pesticide reduction amidst food and feed security concerns in Europe

Nature Food, Год журнала: 2023, Номер 4(9), С. 746 - 750

Опубликована: Сен. 21, 2023

Abstract Recent studies have estimated the potential yield impacts of pesticide reductions in European Union. While these estimates guide policy design, they are often based on worst-case assumptions and rarely account for positive ecological feedbacks that would contribute to sustainable crop yields long term.

Promoting sustainable smallholder farming via multistakeholder collaboration

Proceedings of the National Academy of Sciences, Год журнала: 2024, Номер 121(21)

Опубликована: Май 16, 2024

Transforming smallholder farms is critical to global food security and environmental sustainability. The science technology backyard (STB) platform has proved be a viable approach in China. However, STB traditionally focused on empowering farmers by transferring knowledge, wide-scale adoption of more sustainable practices technologies remains challenge. Here, we report long-term project scale-up for expanding upgrading the original (STB 2.0). We created formalized standardized process which engage collaborate with farmers, including integrating their feedback via equal dialogues designing promoting technologies. Based 288 site-year field trials three regions North China Plain over 5 y, find that cocreated through this were easily accepted increased crop yields nitrogen factor productivity 7.2% 28.1% wheat production 11.4% 27.0% maize production, respectively. In these broadly, “one-stop” multistakeholder program involving local government agencies, enterprises, universities, farmers. was shown much effective than traditional extension methods applied at STB, yielding substantial economic benefits. Our study contributes an important case agriculture. 2.0 being explored emphasizes dialogue collaboration, investment. These lessons may provide value research practitioners.

Intensive food and feed production in sole-cropped, large fields with high fertilizer pesticide inputs to achieve yields, has contributed detrimental environmental impacts. To move towards more sustainable agricultural landscapes, cropping system diversification been suggested as a promising practice for which the use of digital technologies could be potentially beneficial. Understanding impact diversified, newly arranged systems their management requires long-term experimental data at landscape scale practical experiences using are hardly available. Experimental platforms an setup farmers' involvement meet such demands but have not set up many regions nor process designing described systematically.

Long-term research is essential for guiding the development of agroecosystems to meet escalating production demands in a manner that environmentally sound and socially acceptable. Research must integrate biophysical socioeconomic factors provide geographically scalable knowledge involves stakeholders across research-education-extension-policy spectrum. In response this need, Long-Term Agroecosystem (LTAR) network developed "Common Experiment," which seeks develop disseminate multi-region, science-based information enable implementation visionary agricultural innovations while simultaneously promoting food security, well-being, environmental quality, climate adaptation mitigation. The core design Common Experiment contrasts prevailing alternative/aspirational systems, with latter including novel hypothesized advance sustainable intensification locally appropriate ways. Treatments represent diversity systems under cropland, grazing land, integrated crop/grazing land management. Where possible, treatments are evaluated at multiple spatial scales (e.g., from plot enterprise) designed evolve over course experiment stakeholder input. A common assessment framework guides data collection complemented by metric-specific protocols an emerging management infrastructure. Currently, there large differences among sites application experimental degree engagement; largely grounded pragmatic issues related access, site expertise, resource availability. full potential LTAR may be realized strategic investments capacity.
