Impacts of climate change on agriculture productivity: A case study of Haryana
Surender Kumar, Priyanka
Climate change is a burning issue of today. Generally, Climate Change means increasing tem of earth surface due to some physical and anthropogenic factors. It influences the earth by increasing its overall temperature. Increase in the temperature of earth accelerates the melting of Glaciers which causes rise in sea level that leads to submerging of more farmland area into sea water. On the other hand increase in temperature also causes reduction in rainfall in the arid plains. Less Rainfall results into reduction in agricultural production. The impact of climate change is being studied in many forms in different locations in various countries by many researchers and various national agencies. All they have a common finding that there is high impact of climate change on agriculture as in comparison to any other sector.
A study revealed that the climatic variation such as occurrences of drought have high level of impact on the yield of rain fed crops. A study projected that with short periods of exposure of wheat crops to temperatures of 28ºC to 32ºC results in significant decrease in its yield by 20% or more. Unpredictable moisture deficits during crop growth are a major constraint to productivity. Furthermore, a study claims that climate change will reduce the major crop yields by 4.5 to 9 percent over the period of 2010-2039. Therefore, change in climate is reducing the agricultural productivity and thus posing a threat to long term food security. This factor motivates to study the impact of climate change on the agriculture production in Haryana.
