Climate Change and Agriculture

Recently, there was a news about multiple farmers’ suicide in Southern part of India as a result of annual crop failure. In areas like southern India, these incidences are quite relevant as the climate there is always dry and arid. But it gets shocking when crops deteriorates some other developed nations. The rate of crop failure is increasing and is becoming more relevant everywhere. Agriculture failure is affecting almost all agrarian areas. No other factors contribute more to this catastrophe than the climate change, also known as global warming. The elevation in the Earth’s average temperature as a result of burning fossil fuels and other natural or human activities produces carbon dioxide, which acts like a heat trapping gas and affects the earth in various ways. Among the most affected areas of climate change, agricultural sector is facing some serious threats through factors like increasing temperature, extreme precipitation, and droughts, etc. Today, agriculture comprise most of the world food supply, but the rising global warming is rapidly limiting the production around the globe.

The most important thing about agriculture is its dependability on the specific climatic conditions. The crops fully functions when the temperature and the land is suitable for the particular crop. Temperature is the main variable that determines if the crop will grow. Plenty of carbon dioxide, produced by climate change, can be beneficial for most plants, but it can be detrimental when the temperature rises along with the carbon dioxide to the abnormal level. Many crop show positive responses to elevated carbon dioxide and low level of warming, but higher level of warming negatively affects the growth and yields (Karl).

Drought, on the other hand, is also associated with many plant diseases. Water deficit can aid many plant destroying pests and insects. Many agricultural pests are expected to thrive in drought conditions because of the warmer temperate (Grayson). As the temperature rises, they eat more and produces younger resulting in an unstoppable life cycle.

Climate Change, in general, is very detrimental to the world’s farming. Agriculture has a strong negative connections with global warming is different ways. The factors like drought, fluctuating temperature, varying seasons make it hard for the farmers to grow crops. The production failure of today can affect the future. The growing population along with the food demand and the problems of heavy crop losses because of global climate change requires the urgent development of plans to improve food availability in future.
