Uzhavar Sandhai is a scheme by the Tamil Nadu government to facilitate direct contact between farmers and consumers without middlemen. The scheme aims to provide fresh fruits and vegetables at reasonable prices to consumers and higher prices than wholesale to farmers. Uzhavar Sandhais function as technical information and training centers for farmers, providing seeds, inputs, and facilities like identity cards, transport, stalls, price fixation, and amenities. They are managed by market committees who coordinate daily operations and price fixation to connect producers and consumers.
