The global impacts of the climate crisis are becoming ever clearer, and natural resources and ecosystems are being depleted. Despite some progress, hunger and poverty persist, and inequalities are deepening. The world is realizing that unsustainable high external inputs and resource-intensive industrialized systems pose a real danger of biodiversity loss, increased greenhouse gas emissions, shortages of healthy food, and the impoverishment of dispossessed peasants around the world. There is global consensus on the urgent need for a transition to agri-food systems that ensure food and nutrition security, social and economic equity, and sustain the ecosystem on which all these elements depend. Agroecology provides a crucial pathway towards this objective. Making extension and advisory services (EAS) demand-driven is not an end in itself but a means to improving their relevance and impact.
