 FAO's Farmer Field Schools have improved the skills of over 20 million farmers, pastoralists and fisherfolk in over 90 countries. By putting the farmers at the heart of the learning and innovation process, Farmer Field Schools empower people, households and communities. Producers meet regularly in their fields, discuss problems, innovations and management techniques, set up experiments, make weekly observations and take joint decisions. They build a deeper understanding of the local agroecosystem. Over the course of 30 years, Farmer Field Schools have grown to cover a wide range of topics, including agroecological farming. Agroecology is a holistic approach that applies ecological and social principles to the design and management of sustainable agriculture and food systems. Farmer Field Schools have a wide range of topics, including agroecological farming. Farmer Field Schools, introduced by FAO in India, have been adapted to focus on regenerating soil using intensive polycropping and agroforestry locally made by a stimulants derived from animals and botanical pesticides. Every week, groups of 20 to 25 producers from the same village meet on their Farmer Field Schools site to do an agroecosystem analysis and monitor their experiments. Two subgroups of farmers monitor the condition of two priority crops, while another subgroup can make visual assessments of soil health. Another group can check all the plants and trees present in a few square meters and discuss the positive synergies between the species which are growing next to or under each other. They will observe which trees will provide support for crops by giving shade, windbreaks, organic matter for soil cover or compost, and fruit. As Farmer Field School members increase their plant diversity throughout the year, nutrition and incomes also improve, and farms become more resilient to extreme climate events and outbreaks of pests such as the Fall Army one. These regenerative agricultural approaches put into practice the concept of one health for ecosystems, animals and people. Agroecological principles are very important because if we maintain the diversity of crops on a piece of land, the diversity of microbes and beneficial insects also increases, hence no need of putting fertilizers and manures and other pesticides and chemicals and all from outside. So we can recycle the nutrients that is from the field to animals or livestock and from the livestock we can keep directly to this field. So we are here to explain about agroecological principles, their diversity, their recycling procedure and the economic principles like year-round income. The FFS people are like a group of people, no caste, no religious basis and they're happy now. The discovery learning process in Farmer Field Schools is ideal to support farmers' learning and innovation on agroecology and offer a practical farmer-driven approach to discover and regenerate the complex web of life sustaining our agroecosystems.
