Cooperative societies are autonomous associations that are voluntarily owned and controlled by their members to achieve mutual social, economic, and cultural benefits. They originated in India to help farmers pool resources for credit, procurement of supplies, and marketing of agricultural produce. Key principles include voluntary membership, democratic control by members, and concern for the community. While cooperatives provide benefits like promotion of savings and self-help, they face issues such as dormant membership, lack of participation in management, and political interference. Programs by organizations like NAFED and NCDC aim to support India's cooperative movement.
