According to the World Bank report, Pakistan has suffered 3.86 billion losses annually due to climate change. The reduction of natural resources, water shortage and food insecurity are some of the risk factors because of rapid climate change trends in Pakistan
The global phenomenon of climate change is altering weather patterns across the country as summers are expanding, winters are shrinking, wet seasons are becoming wetter and dry spell is getting drier.
MAJOR CAUSES OF THIS CHANGE:
- Greenhouse gases.
- Human activities.
The Districts are now tremendously vulnerable to floods/flash floods. Data suggested that annual rainfall in the months of January and February are reducing, rainfall in March, April, May, June, July and August are increasing while rainfall in September, October, November and December is decreasing.
“Climate change is no longer a far-off problem; it is happening here, it is happening now.”
In near-term years rainfall in January, February and March will decrease further, rainfall in April and May will increase, rainfall in June, July and August will decrease and rainfall in September, October, November and December will increase slightly, the data predicted. According to a data, the summer season in the country is mounting by one day per year and for the past 20 years till now the summer season had expanded by almost a month on both sides. Now summer season started in April and continue till early October while beforehand it was from May to August. Similarly the winter season is shrinking by a ratio of half a day per year and so far it had shrunk by five days from both sides. Now winter season starts from early November and persist till end January whereas previously it started in mid October and continued till mid February. Prevailing weather patterns will unfavorably affect the agriculture system of the country, said Maher Sahibzada Khan, Director Met office, Lahore. He said wet spells have become wetter and will become wettest while the dry spells have become drier and will become driest. Discussing reasons for change in weather patterns, he said deforestation; rising levels of pollution, change in land use, rapid urbanization and unintentional industrialization are some of the causative factors in enhancing the impacts of climate change in local conditions.
Impacts of climate change can be mitigated through massive tree plantation, proper urban planning, introducing stable flood management systems and increase in water storage capacity across the country. Impact of climate change include seasonal droughts, severe long-drawn-out droughts, frost, heavy rains, floods & flash floods, tremendous temperatures, odd rains, fog and strong winds, extreme summers, deficient seasonal rainfall, shortage of fresh/drinking water, extreme winters, diseases (malaria/dengue) and allergy (pollen).
- Tree plantation.
- Efficient use of energy.
- Renewable power-sources must be used.
- Water-loss must be controlled.
- 3-R’s should be in practiced.
- Environment friendly shopper bags and fertilizers must be used.
- Conservation practices must be done.
These impacts can smash up water sector, agriculture sector (sowing and harvestings), and tourism sector and health sectors. In a recent monsoon rainfall allotment analysis by the Pakistan Meteorological Department (PMD), it has been reported that over the past three decades the climate change has resulted in a 100 kilometers spatial shift towards west in the overall monsoon outline in Pakistan. Climate Change is the new catastrophe that needs to be addressed at imperative basis.
