Pakistan happens to be among the top ten countries that would be worst affected by the ravages of climate change in the coming decades. Catastrophic floods had hit the country several times and yet no dams or remedies were taken up to mitigate the losses.
The floods not only created human miseries but also resulted in a huge waste of water which could have been enough for ten years of irrigation had we developed a proper irrigation system with dams to save the water.
Pakistani terrain according to experts falls in the semi-arid zone. With the glaciers gone in 50 years, first creating flash floods and then drying the rivers, the country will face acute shortage of agriculture water. The heat waves which have intensified over the years and reduction of rain falls are also predicted to cast a devastating impact on crop production.
Farmers all over the country are perturbed by the sudden change in the climate. Regions are facing a changing pattern of rain falls and cold waves.
These and other natural hazards according to the Climate Change Profile of Pakistan report will increase in frequency and severity in the coming decades. By the end of the century, it’s forecast is that the sea level would rise by 50 centimetres near Karachi and temperature by 3 to 5 degrees centigrades.
The country will soon be afflicted with reduced agricultural productivity, increased variability of water availability, increased coastal erosion and seawater
incursion and increased the frequency of extreme climatic events.
The only option available with the government is to finalise a strategy to deal with the impact of climate change. The public and farmers need to be educated on how to cope with the whimsical nature of the changing regional climate and increase their resilience to damages.
According to the ADB report, Pakistan’s greenhouse emissions will double in two years, surge 14 times by 2050 wiping out the glaciers. Heatwave days per year have also increased by 31 days between 1980 and 2007.
Climate change effects and the rapidly growing population will be the biggest threat to the people in the coming decades.
