Introduction
Water is one of the most critical resources for agriculture, and India, being heavily dependent on monsoon rainfall, faces significant challenges in efficient water management. A large proportion of India’s cultivated land suffers from water scarcity, over-extraction of groundwater, and inefficient irrigation practices. To address these issues, the Government of India launched the National Mission on Micro Irrigation (NMMI), a key component of the National Mission on Sustainable Agriculture (NMSA) under the National Action Plan on Climate Change (NAPCC).
The mission promotes efficient water use, precision irrigation techniques, improved crop productivity, and sustainable agricultural practices, ensuring better resource utilization, enhanced farmer income, and climate resilience.
Background and Need
