The role of agroecology in building more resilient and fair food systems

The document argues that agroecology, a science-based set of practices and social movement, offers a sustainable alternative to industrial agriculture, which accounts for up to 37% of global greenhouse gas emissions. It highlights that approximately 30% of global farms have already adopted agroecological principles, leading to increased crop yields, higher farmer incomes, and improved biodiversity. However, the briefing notes that scaling up these practices is hindered by governance and finance systems that heavily subsidize industrial agriculture, with only 1%-1.5% of agricultural and aid budgets currently supporting agroecological approaches. To overcome these barriers, the document recommends reorienting public funding, integrating agroecology into research and education, and increasing the participation of small-scale producers in food governance.

• Industrial food production is a significant driver of environmental degradation and social inequality, contributing up to 37% of total global greenhouse gas emissions and failing to address world hunger, which affects 8.9% of the global population.
• Agroecology has demonstrated the ability to significantly increase food productivity. In a study across 57 nations, agroecological projects covering 37 million hectares increased average crop yields by 79%, with gains in Africa reaching 116%.
• Transitioning to agroecology provides substantial environmental benefits, including improved soil health and carbon sequestration. Agroforestry can store between 0.1 and 5.7 Gt of CO2 annually on a global scale, and rebuilding soil organic matter could store 20%–35% of current greenhouse gas emissions.
• Agroecological practices improve the economic stability and livelihoods of farmers. Evidence shows profitability increased in 66% and labour productivity in 100% of cases compared to conventional practices, with European farmers seeing income rises between 10% and 110%.
• The expansion of agroecology is severely limited by financial and political structures. Public investment in these approaches is only 1%-1.5% of total agricultural and aid budgets, while global agricultural subsidies of at least USD 600 billion per year primarily support direct income rather than sustainability, with only 5% dedicated to conservation or sustainability objectives.
• Scaling up agroecology requires a systemic shift in governance and funding, including the reorientation of public spending toward farmer-to-farmer networks, the integration of agroecology into agricultural education, and the amplification of voices from indigenous and local communities in policy development.
