Climate Change and Its Regional Impacts on Agricultural Geography

Abstract

The challenge of climate change has been a dynamic menace to agricultural systems as it affects temperature, precipitation, and the occurrence of extreme weather events. As a climate-sensitive sector, agriculture is more vulnerable in one region compared to another; thus, it is imperative to analyse agriculture in terms of geography to be in a position to know its effects. The study explains the effects of climate change on agricultural geography by studying spatial variations of crop productivity, land-use processes, and adaptive capabilities among different agro-climatic regions. The study is based on the forms of a regionally comparative, mixed-methods design, followed by the analysis of data through time-series statistics and multivariate modelling. Climatic and agricultural signals were assessed, ranging from temperature patterns, rainfall abnormalities, harvest operations, and conversion of land-use, in arid, semi-arid, floodplain, and upland zones. The outcomes show a considerable geographical disparity: hot areas underwent the most climate pressure (e.g., temperature growth of 1.8 °C, loss of rain by 12%, and yield down by 22%), and floodplains showed improved yields (+10%) and adaptive infrastructure. Spatial indices proved that both arid and semi-arid areas suffer more vulnerability due to the unavailability of socio-economic and technological capabilities. On the contrary, irrigated plains were more resilient and institution-supported. The study indicates that region-based planning, investments in adaptive technologies, and geographically acceptable policies will help reduce the unequal effects of climate change on the agricultural sector and ensure resilient and sustainable land use.
