Water is vital for agriculture, but in India its availability is declining due to rising demand and climate variability. To address this, improving water productivity has become a priority. Integrating solar power with micro irrigation systems offers a sustainable way to enhance efficiency while reducing dependence on conventional energy. In this study, the potential area for micro-irrigation in India was estimated using two indices. The estimated potential area under micro-irrigation was approximately 88 Mha based on Index 1, which considered the proportion of the area irrigated by groundwater, tanks, other sources, and 30% of canal-irrigated land. Using Index 2, which included the proportion of the area irrigated by groundwater, tanks, other sources, and 50% of canal-irrigated land, the potential area was estimated to be approximately 93 Mha. MI adoption has grown at a Compound Annual Growth Rate of 9.75, reaching 16.73 Mha in 2023-24, with sprinkler irrigation covering 9.04 Mha (54.1%) and drip irrigation 7.68 Mha (45.9%). However, only 15.85% of the estimated MI ultimate potential (105.60 Mha) has been realized, with six states- Rajasthan, Maharashtra, Karnataka, Andhra Pradesh, Gujarat, and Tamil Nadu- accounting for 78% of MI adoption. Despite increasing solar pump installations (501,673 in 2022-23), their correlation with MI remains weak. Policies must address administrative inefficiencies, enhance incentives, and promote integrated solar-powered MI adoption to maximize sustainability and groundwater conservation.
