Tank performance and its impact on rural livelihoods of tank commands in Andhra Pradesh, India: a spatial analysis approach.

This study examines the impact of poor tank performance in Andhra Pradesh, India, focusing on nonsystem and system tanks. Data analysis reveals declining tank performance over the past three decades, with average performance at 58.39% for non-system tanks and 87.4% for system tanks in 2021. Non-system tanks show favourable gross farm revenue and water user association characteristics, with siltation negatively affecting the performance. System tanks benefit from better foreshore and water spread area maintenance, reducing siltation and encroachment issues. Recommendations include Government initiatives for desiltation, strengthening water user associations, and promoting less waterintensive crops to address tank performance challenges.
