Abstract
In Semi-Arid Tropical (SAT) region of India, agriculture supports livelihood of over 70 per cent of the population. However, the region faces uncertain rainfall and frequent droughts and hence, irrigation is crucial for drought proofing and productivity enhancement. The study was undertaken to investigate the trends and status of irrigation development in SAT region (erstwhile Andhra Pradesh, Karnataka and Tamil Nadu states). Demand-supply scenario of irrigation water was also assessed for the lower Krishna basin in the region. Further, the study also attempted to evaluate the performance and constraints of Water User Associations (WUAs) in the Krishna basin under the framework of new institutional economics. There has been a structural shift in favour of groundwater irrigation and deterioration in surface irrigation systems in SAT region. Further, districts with poor rainfall were found to have higher concentration of groundwater irrigation. However, the overexploitation of groundwater in Tamil Nadu is posing threat to the sustainable development. Capital investment had accounted for a major share in public irrigation expenditure in Andhra Pradesh and Karnataka. However, in Tamil Nadu, revenue expenditure had accounted for the major share. In recent years, adoption of drip irrigation in Andhra Pradesh and Tamil Nadu, and sprinkler irrigation in Karnataka was found to be impressive. The demand and supply analysis of irrigation water indicated a huge irrigation water deficit in the lower Krishna basin. The performance of WUAs in relation to equitable distribution of water among head, middle and tail reaches, and financial viability was found to be poor. The study found expertise in governance, active leadership and ensuring compliance of rules as important factors for ensuring equitable distribution of water. Major constraints faced by WUAs in canal water management in the Krishna basin were related to operation and maintenance of canal system, free rider problem and failures in policy implementation. Therefore, sustainable and equitable development of irrigation in water scarce SAT region needs both supply side management through adequate financial support, capacity building and monitoring of WUAs, and demand side management through faster promotion of water efficient irrigation technologies such as micro irrigation.
