Greenhouse Gas Emissions, Carbon Sequestration in Cropland and Crop Yield Limiting Factors

İngilizce (OpenAlex)

Global warming has seriously affected human survival and sustainable development of agriculture. The direct cause of global warming is likely to be the excessive emission of greenhouse gases. Greenhouse gases mainly include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3) and water vapor. Due to the rapid change of global climate, the situation has further deteriorated. In crop production, drought is undoubtedly the most important stress which has a great impact on crop growth and productivity. Understanding the physiological, biochemical and ecological interventions associated with these stresses is important for better management. Abiotic stress is one of the main constraints of crop production and food security in the world. This review explores the scientific foundations of greenhouse gas emissions and carbon sequestration in agricultural lands. It examines the negative impacts of drought stress on plant responses, crop growth, and yield formation. Additionally, it assesses the gap between actual yields and potential yields, highlighting the limiting factors that have not been adequately addressed. This issue is prevalent in agricultural production across all countries.
