Climate change impacting agriculture productivity

Islamabad: Agriculture productivity is being affected by a number of factors of climate change including rainfall pattern, temperature hike, changes in sowing and harvesting dates, water availability, evapotranspiration and land suitability.
According to a case study the impact of climate change on agriculture is many folds including diminishing of agricultural output and shortening of growth period for crops.
It underlined that main issue of climate change is global warming. Therefore, researchers have to produce heat resistant seeds. The climate change may change the level of precipitation as well as pattern and directions of rainfall. So, drought resistant seeds have to be developed in time.
The increasing population requires more cultivable land for wheat production. Water conservation management and the irrigation system have to be improved. The increasing temperature may shorten the period of growth for wheat canopy so time of wheat cultivation should also be adjusted accordingly.
It concluded that the newly emerging threat of climatic change may influence the level of wheat production in Pakistan. Being an agricultural country Pakistan should be capable to secure domestic consumption by increasing the level of wheat production and the surplus production can be exported abroad to earn foreign exchange.
