Variability of Rainfall in Punjab and its impact on Wheat Crop

There is one issue that will define the contours of this century more dramatically than any other and that is the urgent threat of changing behaviour of precipitation that poses risk for human and natural resources.Pakistan is an agrarian country, its economy depends upon agriculture. Among all the province Punjab is most agricultural province, where cotton rice and wheat are grown.But in northern chunk and some parts of southern areas of the province, wheat yield totally depends upon rainfall.So, rainfall pattern is highly correlated with yield production.Thus it is dire need of time to understand the spatial and temporal behaviour of rainfall over the province.
