Bihar strengthens its climate resilience using Systematic Catchment Area Treatment

16 October 2020

The Kaimur and Rohtas districts in the State of Bihar, India, are rich in biodiversity and wildlife.

To address the rising water stress and changing climatic patterns in the region, the Durgawati Reservoir project was conceived. Under this project, a reservoir was built on the Durgawati river which forms the boundary of the Rohtas and Kaimur Districts of Bihar. The reservoir and subsequent submergence zone became functional in 2014-15.

In order to check soil erosion and promote water conservation in the region, a Catchment Area Treatment (CAT) Plan was also devised. The CAT Plan will cover 51,657 hectares which is 97% of prime forest land, thereby benefitting both local villages and wildlife population.

As a result of the CAT Plan, the region has seen improvements to:

  • Soil conservation
  • Soil moisture regime
  • Availability of water

This case study was developed as part of the India States Climate Leadership Project of the Under2 Coalition.
