A Study on Assessing the Effects of Extreme Weather Events on Agriculture in the Indian Subcontinent

Abstract The Indian subcontinent, characterized by its diverse agro-climatic zones, is increasingly vulnerable to the adverse impacts of extreme weather events such as heatwaves, cyclones, floods, and droughts, all of which are exacerbated by climate change, and this study aims to theoretically assess the multifaceted effects of such events on agriculture, focusing on their spatial and temporal variations, adaptive capacities of farming communities, and the implications for food security. Extreme weather events in India have led to considerable disruptions in agricultural productivity, with crop failures and loss of livelihood for millions of farmers, particularly in regions heavily dependent on monsoon rains, such as the Indo-Gangetic plains and parts of central India; these climatic anomalies have caused substantial reductions in crop yields for staple crops like rice, wheat, and maize, as evidenced by the 2019 monsoon failure that affected over 10 million hectares of farmland, resulting in significant economic losses. The theoretical framework of this study draws on the vulnerability and resilience theory to analyze how various socio-economic, environmental, and institutional factors influence the capacity of farmers to adapt to such events, and incorporates a comparative approach using recent data from the Indian Meteorological Department (IMD) and remote sensing technologies, along with climate models from the Intergovernmental Panel on Climate Change (IPCC), to understand the shifts in agricultural patterns. Additionally, this research emphasizes the role of socio-economic determinants such as farm size, access to resources, and technological adoption in shaping vulnerability, and explores policy frameworks that could mitigate the adverse effects of extreme weather, including early warning systems, climate-resilient crop varieties, and improved water management practices, which are crucial for sustaining agriculture in the face of increasing climatic variability. By utilizing a mixed-methods approach, combining spatial analysis, case studies from drought- and flood-prone areas, and policy analysis, this study seeks to provide a comprehensive theoretical understanding of the complex interplay between extreme weather events and agricultural systems in India, highlighting the need for integrated, multi-dimensional solutions to safeguard food security and support rural livelihoods. The findings underscore the urgency of incorporating climate adaptation strategies into national agricultural policies and the importance of strengthening the resilience of farming communities to ensure sustainable agricultural development in the face of a changing climate
