Climate change impact on soil health and crop production

Abstract

Climate change has emerged as a defining challenge of the 21st century, profoundly affecting natural systems and human societies worldwide. One of the critical aspects of this phenomenon is its impact on carbon sequestration and crop production, which play vital roles in global carbon cycling and food security. The increase in greenhouse gas emissions due to human activities has led to a rise in global temperatures, altered precipitation patterns, and intensified extreme weather events like droughts and floods. Alterations in temperature, precipitation patterns, and the frequency of extreme weather events influence soil processes, accelerate microbial activity, moisture levels, disrupt soil structure, leading to the erosion of organic matter which impacts on carbon sequestration potential. Furthermore, the intricate relationship between climate change and crop production has significant implications for global food security. Altered temperature and precipitation patterns can disrupt plant phenology, water availability, and nutrient cycling, leading to yield variability and decreased agricultural productivity. Pests and diseases also find new opportunities for proliferation in a changing climate, adding additional stress to crop production systems. Shifts in suitable growing regions for various crops further complicate the dynamics of agricultural adaptation to a changing climate. Agriculture practices possesses the potential to mitigate them by acting as a carbon sink. The development and cultivation of climate-resilient crop varieties, precision agriculture technologies, and improved water management techniques are crucial for safeguarding crop production in a changing climate.
