How can rainwater harvesting to enhance water productivity of rain fed agriculture in the semi-arid areas?
Rainwater harvesting through farm ponds stores runoff water and is used for supplemental irrigation/life-saving irrigation at critical stages of the crop (generally flowering and grain/pod filling stage) during prolonged dry spells which are common in semi-arid regions. This life-saving irrigation increases water productivity.
Rainwater harvesting enhances water productivity in rain-fed agriculture in semi-arid areas by capturing and storing rainfall for use during dry periods. This practice improves soil moisture, extends the growing season, and increases crop yields. By reducing reliance on erratic rainfall, it stabilizes agricultural output, promotes efficient water use, and supports sustainable farming practices. Additionally, rainwater harvesting helps recharge groundwater, reduces soil erosion, and enhances overall farm resilience to climate variability, thereby improving the livelihoods of farmers in semi-arid regions.
