The Department of Environment, Forest and Climate Change (DoEFCC), Government of Bihar, serves as the nodal agency for protecting and sustainably managing the state’s natural resources while coordinating climate action across departments.

Its core mandate protects forests, wildlife, wetlands, biodiversity, and ecosystems, while fostering sustainable biological resources. Key priorities include boosting tree cover beyond forests, enforcing forest and environmental laws, and aligning with the National Forest Policy through afforestation, native species restoration, biodiversity conservation, and rainwater harvesting.

Bihar pursues sustainable forest management tailored to its context, leveraging modern tools like Information Management Systems (IMS) and Geographical Information Systems (GIS), alongside institutions such as a Climate Change Knowledge Centre. The department tackles climate mitigation and adaptation, human-wildlife conflicts, endangered species like the Gangetic dolphin via the proposed National Dolphin Research Centre in Patna, pollution control, ecosystem management, and market linkages for forest products and agroforestry to boost farmer incomes. These efforts propel Bihar toward environmental resilience."
