"Watershed is the most appropriate spatial unit for planning." Comment.
Watersheds, defined as the catchment areas of rivers and their tributaries, provide natural boundaries for planning, making them ideal for integrated resource management. They facilitate soil and water conservation, prevent floods, and support sustainable agriculture. Watershed-based planning ensures holistic development of land, water, vegetation, and human resources within the natural hydrological unit.
In India, watershed management has improved agricultural productivity in rainfed areas of Rajasthan, Maharashtra, and Karnataka. Programs like Integrated Watershed Management Programme (IWMP) promote community participation, enhance groundwater recharge, and reduce soil erosion. By aligning planning with the natural drainage system, watersheds help optimize resource allocation, maintain ecological balance, and reduce inter-regional conflicts over water use.
