The multifaceted impact of climate change on agriculture and biodiversity: An integrative assessment

Abstract

The 21st century presents formidable challenges, including climate change, energy supply, health and disease invasion, and the need for a sustainable environment. Among these, climate change poses a significant threat, particularly to biodiversity and food security, with narrowly adapted and endemic species being the most vulnerable. India, with its unique geography, history, and culture, is distinguished by its remarkable diversity of natural ecosystems. It is one of the twelve mega biodiversity hotspots globally, reflecting the breadth of its biological diversity. This study offers a comprehensive analysis of the impacts of climate change on four interconnected domains in India: agriculture, land resources, water resources, and biodiversity. Our findings reveal that rising temperatures, altered precipitation patterns, and the increased frequency of extreme weather events are significantly undermining India's agricultural productivity, which in turn poses serious risks to food security. Land degradation and desertification are accelerating in vulnerable regions, while water resources are under increasing pressure due to factors such as glacial retreat, shifting monsoon patterns, and heightened evapotranspiration rates. Furthermore, India's rich biodiversity is at risk, with shifts in species distribution and potential extinctions on the horizon. The study underscores the intricate interplay between these sectors, highlighting the urgent need for integrated adaptation strategies. We conclude by proposing a framework for policy interventions that address these challenges holistically. This framework emphasizes the importance of sustainable resource management, climate-resilient agricultural practices, and ecosystem conservation as essential strategies for mitigating the impacts of climate change on India's natural and agricultural systems.
