Agroecology for a Sustainable Agriculture and Food System: From Local Solutions to Large-Scale Adoption

Abstract

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

Europe's ambitious pesticide policy and its impact on agriculture and food systems

“…This may include new farming systems as well as digital innovations such as precision agriculture, robots, and the use of digital technologies to redesign future agricultural landscapes (Möhring et al, 2020). It may also include new production systems based on agroecological crop protection and the use of new breeding technologies to create pest-resistant varieties (Ewert et al, 2023).…”

Sustainable transformation of agriculture requires landscape experiments

“…Among existing concepts, aiming to achieve different goals of sustainable agriculture (e.g., organic agriculture [ 17 ] or sustainable and ecological intensification [ [18] , [19] , [20] , [21] ]), agroecology is widely recognised as an all-encompassing approach, which considers “how agricultural practice and research can be geared to the needs of people and the planet” [ 22 ]. It links nature and technology, productivity and natural resources, scientific and traditional knowledge, social and cultural values [ [22] , [23] , [24] , [25] ]. Though agroecology encompasses the global food system at its highest level, its lower levels describe the practical steps that farmers can take within their farms [ 26 ], at the scales of field or farm and beyond.…”

Socio-Economic Problems of Agricultural Laborers in Punjab (Pakistan)

“…Agriculture laborers play a crucial role in providing food, reducing hunger and national development, but unfortunately, the socioeconomic condition of these laborers is deplorable. The laborers working in the agriculture sector have to face multidimensional issues such as poor socioeconomic, health, livelihood, employment conditions, remuneration, education, nutrition, safety and social protection, among others (Khan et al, 2021;Rautela et al, 2022;Ewert et al, 2023). Lack of proper safety measures, long working hours, fewer rewards, unavailability of essential health and education facilities, and involvement of procedural matters make things more complicated for this sector and the laborers (Milheiras et al, 2022).…”
