BharatNotes What is Watershed Management?
A watershed (drainage basin or catchment) is a hydrological unit of land from which all rainfall drains through a common outlet — a stream, river or point. Watershed management is the holistic conservation, regeneration and sustainable management of natural resources — land, water and vegetation — within that unit, with the twin aims of conserving soil and rainwater and improving agricultural productivity and rural livelihoods.
The guiding principle is the ridge-to-valley approach: treatment begins at the highest point (the ridge) and works downslope so that run-off is detained, diverted, stored and used at every stage, reducing both the volume and velocity of water reaching the valley. This integrates soil conservation, rainwater harvesting, afforestation/agroforestry, land-use planning and community participation into one coordinated framework.
Key Features
- Ridge-to-valley treatment — contour bunds, check dams, gully plugs, farm ponds, percolation tanks and trenches staged from upper to lower reaches.
- Participatory, community-led — Watershed Committees and Self-Help Groups plan and maintain assets.
- Cluster scale — projects typically treat watershed clusters of about 1,000–5,000 hectares.
- Technology-driven — WDC-PMKSY 2.0 mandates GIS and remote-sensing for planning and monitoring.
- Convergence — works dovetail with MGNREGA and other rural schemes in a "saturation" mode.
Evolution of India's Programmes
| Programme | Launched | Note |
|---|---|---|
| Drought Prone Areas Programme (DPAP) | 1972-73 | First major scheme |
| Desert Development Programme (DDP) | 1977-78 | Hot & cold deserts |
| Integrated Wastelands Development Programme (IWDP) | 1989-90 | Wasteland focus |
| NWDPRA | 1990 | Rainfed areas |
| Integrated Watershed Management Programme (IWMP) | 2009-10 | Merged DPAP, DDP, IWDP |
| WDC-PMKSY | 2015-16 | IWMP folded into PMKSY |
| WDC-PMKSY 2.0 | 2021-2026 | Current phase |
The Neeranchal National Watershed Project (2016–2022), a World Bank-assisted project of about Rs 2,142 crore (US$178.50 million credit, signed Jan 2016), supported institutional strengthening of the watershed component.
Current Status (WDC-PMKSY 2.0)
WDC-PMKSY 2.0 was approved by the Government of India on 15 December 2021 for 2021-2026, with a physical target of 49.50 lakh hectares and an indicative central outlay of Rs 8,134 crore (DoLR figures). The unit cost was raised to Rs 22,000/ha for plains and Rs 28,000/ha for difficult and LWE areas, and the project cycle shortened to 3–5 years. On NITI Aayog's recommendation, springshed rejuvenation was added as a new activity. In January 2025, the Ministry of Rural Development sanctioned 56 new projects across 10 best-performing states covering about 2.8 lakh hectares of degraded land.
UPSC Angle
This is a foundational GS3 theme spanning dryland/rainfed agriculture, water resources and drought management, with a GS1 physical-geography overlap on drainage basins. Prelims rewards knowing the programme chronology and the implementing ministry; Mains rewards a critical view of the ridge-to-valley participatory model — its groundwater and livelihood gains, convergence with MGNREGA, and equity and maintenance challenges.
