Transformative Impact of Agromet Advisory Bulletins on Resilience and Profitability in South Bihar under Climate Change

This study evaluates the effectiveness of Agromet Advisory Bulletins (AABs) issued under the Gramin Krishi Mausam Sewa project in enhancing agricultural resilience and profitability across 17 districts of South Bihar. Based on feedback from 1,850 farmers, the adoption of AABs led to yield increases of 5%–29% across major crops and reductions in cultivation costs by 3%–23%, resulting in substantial gains in net income and benefit–cost ratios. The findings demonstrate that timely, weather-based advisories significantly improve resource use efficiency and strengthen the economic sustainability of farming systems. Overall, the study establishes AABs as a critical tool for advancing climate-smart agriculture and ensuring food and livelihood security in climate-vulnerable regions.
