Watershed management is the practice of slowing down rainwater runoff and directing it into the ground using structures like trenches, bunds, gully plugs, and check dams. It helps recharge groundwater, prevent soil erosion, improve soil fertility, and strengthen water security in rainfed areas.

The purpose of contour trenches is to slow down rainwater runoff along slopes and reduce soil erosion. By digging trenches along contour lines, water is held in place long enough to seep into the ground. This improves soil moisture, supports vegetation growth, and enhances groundwater recharge, especially in drought-prone areas.

With unpredictable rainfall and degrading soils, watershed management secures water, improves soil health, and strengthens agricultural productivity. By capturing rainwater and recharging groundwater, it builds long-term resilience for rural communities in rainfed regions.
