Abstract
To enhance our comprehension of agriculture's role in addressing climate change, accurate assessment of its capacity for carbon sequestration is crucial. This assessment encompasses multiple considerations, including regional climate patterns, crop choices, soil management practices, and soil types. Climate change poses a significant threat to food and nutritional security on local, national, and global scales. The amplified concentrations of greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), present immediate challenges. Vulnerable populations, especially those in impoverished conditions, face heightened risk of food insecurity due to the impacts of climate change. Additionally, the conversion of non-agricultural land, like forests, into agricultural use, and human-generated emissions of greenhouse gases from agricultural activities significantly contribute to climate change. The escalating concentration of greenhouse gases, particularly CO2, in the atmosphere leads to global warming. Over the last century (1906–2005), the global mean surface temperature has risen by approximately 0.60 to 0.90°C, with the most rapid increase occurring in recent decades. The global average temperature continues to steadily climb and is projected to rise by 2°C by 2100, potentially resulting in significant global economic losses. The increasing concentration of CO2, a major greenhouse gas, is a cause for concern. This rise has fostered enhanced plant growth and productivity due to increased photosynthesis. However, the benefits of heightened photosynthesis are offset by higher temperatures, leading to increased crop respiration rates, greater evapotranspiration, heightened pest infestations, shifts in weed species, and reduced crop durations. This paper reviews the literature on climate change, its potential drivers, its effects on agriculture, and its influence on the physiological and metabolic processes of plants. It also explores potential and reported implications for plant growth, productivity, and mitigation strategies. In recent years, there has been a growing recommendation for the adoption of conservation agriculture as a more sustainable alternative to conventional farming practices. Conservation agriculture not only supports soil health but also enhances agricultural productivity, making it a crucial tool for mitigating the impacts of climate change.
