Tank Irrigation

This report by Institute for Resource Analysis and Policy attempts to address issues related to groundwater management in Andhra Pradesh. With 49 per cent of the total irrigation from groundwater, the state of Andhra Pradesh accounts for 5.3 per cent of the net groundwater irrigated area in the country. While the state remains as one of the largest exporters of rice, with paddy accounting for nearly 70 per cent of the state’s total irrigated area, groundwater depletion poses serious challenges to not only the agricultural production and rural livelihoods, but also to the nation’s food security.

This paper discusses the advantages of system of rice intensification over normal paddy cultivation. The researcher compare the performance of System of Rice Intensification (SRI) and normal rice fields in two mandals (subdistricts) of Mahabubnagar district of Andhra Pradesh. The yields from these two systems and agronomics are compared.Read More

The need to find less water intensive methods of agriculture become important as there is a reduction in the scope of enhancing irrigation base for increase in food production. It is in this context that this research has been carried out.
