Pakistan is an agrarian country but due to environmental changes, the situation has continuously been reducing cultivable land in addition to affecting our overall agricultural production. Greenhouse effect is a major cause of reduction in farm yield in Pakistan.

Climate change affects economic development in many ways, especially the agrarian economies have always depended on vagaries of nature and climate. Change in temperature, precipitation averages and extreme climate events can alter yield, income, health, sociology and physical safety. Climate change is a global phenomenon and no country is immune to it.

The disappearing of the Himalayan glaciers at a fast pace would increase the probability of extreme water flows, rendering it uncontrolled will bring heavy floods, loss of life, livestock, crops and infrastructural facilities in Pakistan.

Pakistani scientists should develop new varieties of cash crops which should be heat tolerant and can give proper yield with minimum intake of water.
