Successive crop failures in the arid Deccan plateau and groundwater depletion prompted the Food and Agriculture Organization to work with farmers’ collectives and launch the Andhra Pradesh Farmer Managed Groundwater Systems project in 2004. It brought together over 30,000 farmers from 638 villages, who were taught to make optimal use of rain, groundwater, canal and waste water; grow water-saving rice varieties and crop diversification; manage sub-surface water and reclaim land lost to salinity. Maharashtra now has similar projects, along with Gujarat, Odisha and Tamil Nadu.
