Extensive geographical coverage
As of 2017–18, interventions spanned 570 watersheds across 14 districts of Tamil Nadu — including Karur, Tirunelveli, Pudukkottai, Virudhunagar, Krishnagiri, Sivagangai, Tiruvallur, Dharmapuri and Salem.
Flagship initiative of the Department of Land Resources, Ministry of Rural Development — delivered by Coodu Trust with the District Watershed Development Agency across 14 districts of Tamil Nadu.
The project
Restore the ecological balance of degraded landscapes by treating watersheds in a holistic and integrated manner — harnessing, conserving and developing soil, water and vegetative cover to prevent soil erosion, regenerate vegetation, harvest rainwater and recharge the groundwater table.
The Integrated Watershed Management Programme (IWMP) is a flagship initiative of the Department of Land Resources, Ministry of Rural Development, Government of India. Coodu Trust serves as a key implementing partner, working in close coordination with the District Watershed Development Agency (DWDA). As of 2017–18, interventions spanned 570 watersheds across 14 districts of Tamil Nadu — treating 33,500 hectares and reaching approximately 1,70,000 households, a population of over 8,50,000 people.
The strategy is centred on effective community participation, ensuring development plans are based on local needs and land capabilities. In the 2022–2024 focus districts — Pudukkottai, Ramanathapuram, Virudhunagar, Perambalur, Dharmapuri, Krishnagiri and Thoothukudi — Coodu Trust acts as coordinating agency for training and exposure visits to agricultural institutions such as TNAU and KVK Gandhigram.
Why this work matters
On degraded landscapes, rain runs off instead of soaking in — eroding topsoil, stripping vegetative cover and leaving the groundwater table unreplenished.
570 watersheds treated across 14 districts — 33,500 hectares under soil and water conservation, rainwater harvesting and groundwater recharge that regenerates vegetation across the landscape.
When households depend on one crop from degraded land, incomes stay low and every failed season pushes families deeper into hardship.
Livelihood promotion enabled multi-cropping and diverse agro-based activities, backed by extensive training and exposure visits to institutions like TNAU and KVK Gandhigram.

Outcomes
As of 2017–18, interventions spanned 570 watersheds across 14 districts of Tamil Nadu — including Karur, Tirunelveli, Pudukkottai, Virudhunagar, Krishnagiri, Sivagangai, Tiruvallur, Dharmapuri and Salem.
The programme reached approximately 1,70,000 households — a population of over 8,50,000 people — and treated a total area of 33,500 hectares across Tamil Nadu.
By strengthening community-based institutions and promoting sustainable agro-based activities, IWMP enhances household incomes and builds long-term environmental and economic resilience.
