How environmental factors influence agricultural yields
Change in climate is considered to be a global phenomenon, however it impacts are more widely felt in the developing countries due to their greater vulnerabilities and lesser ability to reduce the effects of climate change. Therefore, the major impact of climate change is on agricultural production due to changes in rain pattern, temperature, floods, droughts, and negative effects on water and land resources. Global agricultural production is challenged by climate change. Climate change affects different crops and regions differently, but it is generally expected that agricultural productivity will decline. In fact, some decline can already be seen. According to one calculation, climate change resulted in the reduction of global maize yield by 3.8% between 1980 and 2010. Farmers were not threatened evenly compared to crops, but they were the most vulnerable group to climate change. It is expected that the majority of the impact of climate change will affect the agriculture sector the most due to its vulnerability. The variability in climate change presents a major challenge to agricultural production and rural livelihoods, as it affects approximately billion people who are partially or completely dependent on agriculture. The agricultural sector is highly dependent on alterations in climatic...
