Impact of Climate Change and Global Warming on Agricultural Crop Shifts: Challenges and Adaptation Strategies

Abstract

Climate change has become one of the most highly active agents of agricultural change especially in the redistribution of the patterns of crops distributed across regions. Increased temperatures, changes in rainfall regimes, extreme weather events, and changing Agro-ecological zoning are transforming the suitability of the traditional crops in India like major cereals, millets and horticultural crops. This paper presents the complex effects of climate change on distribution of crops, the effects it has on food security, livelihoods and sustainable agricultural practices. Although the changes brought about by climate are a problem to the crop yield including unpredictability in yields, pests and diseases, lack of water, etc., it can also lead to crop diversification, introduction of more resistant varieties of crops, and new technologies. Adaptation and mitigation interventions, such as adoption of drought- and heat-resistant seeds, better irrigation modes, agroforestry, soil management and precision farming are pointed out as the main avenues of improving resilience. Localized adaptation strategies can be incorporated by policy measures, the framework of international cooperation like the Paris Agreement and provision of international cooperation necessary to deal with regional vulnerabilities. The paper also presents research gaps that are considered critical such as the absence of long-term records of regional crop suitability, the under researched role of pests and diseases, and the absence of combination models of climate, economic and trade effects. The results highlight the concern of active policies, farmer education, and scientific advances to make agriculture sustainable against climate change. Crop shifting, therefore, is not only a challenge but also an opportunity to reimagine agricultural resilience and achieve food security in a changing climate.
