ABSTRACT
Water is among the key requirement for survival on earth. Pakistan was surplus in water resources in the past is moving towards deficiency. Although water crisis is fundamentally a global issue, however its implications will be more severe in developing countries. Nevertheless, the climate change impacts will have greater risk for developing countries like Pakistan. Pakistan with a high and fast growing population lacks enough economic resources to satisfy the basic needs of masses. Furthermore, the future of Himalayan glaciers at risk due to emerging climate change in the region. Pakistan is located in rid region where the issue of water security is forefront problem particularly for agricultural sector. While its use in various sectors like industrial and urban push the country further into water crises. The purpose of present research is to highlight the significance of water resources and shift in rainfall trend in Pakistan focusing on agriculture sector. Data on rainfall and temperature was taken from (PMD) Pakistan Metrological Department for the period of 1980-2011. The data was analyzed through descriptive statistical tolls and Arc GIS 9.8. Result suggests that climate change has severe implications on variation in temperature and rainfall of Pakistan. The after effects of climate change are variation in temperature, changing precipitation patterns and vulnerability of glaciers to climate change. Based on the findings it is suggested the effective climate change adaptation strategies and policies must be taken serious in the country. The government may formulate long term and short term climatic risk strategies to analyze the existing and future effects due to climate change. To avoid water shortage in the country construction of new dames are necessary for future requirement of the country.
