The Palamu Tiger Reserve (PTR) in Jharkhand has adopted an innovative water conservation technique inspired by practices used in Israel and parts of Africa to improve groundwater recharge, strengthen wildlife habitats, and combat water scarcity in the drought prone region.
As part of the initiative more than 50,000 half moon shaped shallow trenches have been created across a 400 hectare grassland area. The project aims to improve rainwater retention, maintain soil moisture, and enhance the reserve’s ecological health. The grasslands were developed to support a stronger prey base for wildlife and improve habitat conditions within the reserve.
According to PTR Deputy Director Prajesh Kant Jena, the project is expected to significantly boost groundwater recharge and has the potential to retain nearly 4.5 lakh litres of water. The effort forms part of the reserve’s broader strategy to improve long term ecological sustainability.
Unlike conventional contour trenches used in agricultural landscapes, the structures created in the reserve are shallow and crescent shaped. Officials modified the traditional design to ensure that animals can move freely through the area without the risk of injury.
Jena explained that deep trenches are unsuitable for wildlife zones because they can become hazards for animals. The half-moon structures are designed to slow surface runoff, capture rainwater, reduce soil erosion, and retain moisture in the ground while remaining safe for wildlife.
Another key feature of the system is its interconnected design. Water collected in one trench gradually flows into nearby structures, helping distribute moisture across a larger area and improving overall water retention throughout the grassland ecosystem.
Forest department officials said similar techniques have proven effective in restoring degraded landscapes in countries such as Israel and South Africa. However, the Palamu model is being described as the first initiative in India to combine watershed management, grassland development, and wildlife conservation in a single integrated framework.
The project has been launched under the “Revive the Rivers” programme and is expected to reduce water stress, encourage vegetation growth, and improve habitat quality without requiring continuous human intervention.
Officials believe the initiative could serve as a model for other protected areas facing similar challenges from drought and declining groundwater levels. The forest department is also exploring the possibility of documenting and patenting the approach, citing its unique blend of conservation and water management techniques.
With climate change and water scarcity posing increasing challenges to wildlife reserves across India, the Palamu Tiger Reserve’s experiment could offer a practical and sustainable solution for conserving both water and biodiversity in fragile ecosystems.
