Bihar’s Gaya district, is not only a site of immense cultural and spiritual significance—known as the place where Buddha attained enlightenment—but also a region increasingly vulnerable to climate impacts. Gaya faces severe challenges such as rising temperatures, erratic rainfall, and frequent droughts, which threaten its agriculture, water resources, and overall livelihood security. These vulnerabilities make Gaya a critical area for focused efforts on climate resilience and sustainable development. The Jal-Jeevan-Hariyali Mission (JJH Mission) aims to address these issues through integrated water management and ecological restoration through active community involvement. This mission is essential not only for enhancing water availability but also for promoting climate resilience and sustainable livelihoods in Gaya among other things. Understanding the best practices under this mission is vital for informing future climate action strategies in Bihar and similar regions.
