Agroecological Transitions in Sustainable Agriculture
Summary
Agroecological transitions represent a paradigm shift from input-intensive, linear models of production towards regenerative, biodiversity-rich systems that integrate ecological principles into farm design and management. Central to this approach is the re-establishment of nutrient and energy cycles, the diversification of crops and livestock, and the integration of landscape elements such as hedgerows, agroforestry and wetland buffers. These transitions aim to reduce dependence on synthetic fertilisers and pesticides, lower greenhouse gas emissions, enhance soil health and water quality, and bolster resilience to climatic extremes. They also promote socio-economic viability by strengthening localised food networks, preserving cultural knowledge and creating rural employment opportunities. Practical applications range from the adoption of cover crops and intercropping to novel pest-management strategies based on natural predator–prey relationships. Success often hinges on multi-stakeholder collaboration across policy, research, industry and farming communities, supported by adaptive governance and participatory monitoring. Globally, regions as diverse as sub-Saharan Africa, South America and Europe are exploring context-specific agroecological pathways, tailoring principles to local biophysical conditions and socio-economic realities. While the pace of transition varies, cumulative evidence underscores the potential of agroecological systems to deliver food security alongside ecosystem services. Challenges remain in scaling these models, quantifying long-term benefits and aligning incentives, yet emerging frameworks emphasise co-innovation, farmer networks and knowledge exchange as levers for wider adoption.

Agroecological Transitions in Sustainable Agriculture publication trend
The graph below shows the total number of articles in agroecological transitions in sustainable agriculture across all publications each year (not limited to Nature Index journals).
Technical terms
Energy Return on Investment (EROI): Ratio of energy outputs (produce) to total energy inputs (external and internal) in an agroecosystem.
Internal Biomass Flows: Movement and recycling of organic matter (crop residues, manure, litter) within a farm system.
Circular Bioeconomy: Model emphasising the reuse of biological resources and waste minimisation to close nutrient and energy loops.
Ecological Intensification: Enhancement of productivity through ecological processes (e.g. pollination, nutrient cycling) rather than synthetic inputs.
Emissions Intensity: Greenhouse-gas emissions per unit of agricultural output, reflecting efficiency improvements in production.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
