Pakistan ravaged by climate change

Pakistan ravaged by climate change

For Pakistan, 2022 could remain the year of all climatic disasters. First, there were infernal heat in the spring, reaching 50 degrees in some localities in May and aggravating the melting of the glaciers in the high mountains and the drought in the plains; then, since the early onset of the monsoon in mid-June, torrential rains, combined with floods, submerged a third of the country.

That “exceeds any limit, any standard observed in the past”, alerted, on August 29, in an interview with AFP, the Minister of Climate Change, Sherry Rehman – including the floods of 2010, which claimed 2,000 victims. The current toll, which is worsening hour by hour, is very provisional due to the difficulty for relief workers to reach villages located in remote mountainous regions and cut off from the rest of the country by the destruction of roads or bridges, carried away by the waves.

“We are used to the monsoon every year, but have never seen anything like it”recalled the Minister. “Eight weeks of constant showers” which hit hardest in regions already heavily affected by the high spring temperatures.

During this period, both Pakistan and northwestern India recorded temperatures of 6 to 9 ° C above seasonal norms, according to the Pakistan Meteorological Service.

The monsoon started in June, earlier than expected. July 2022 was the wettest month in over sixty years (1961).

Balance sheet at 1er September 2022

Pakistan is particularly vulnerable to climate change. It is in eighth position among the countries most affected by extreme weather events, according to a study by the NGO Germanwatch published in 2021. Its population, weakened by poverty and growing inequalities, is particularly exposed to climatic hazards. And the public authorities, bogged down in repeated political crises, have not yet managed to put in place effective prevention and risk management strategies. Pushed to the limits of its ability to adapt by climate change, Pakistan may take time to recover from this new disaster.

La Nina

The cold equivalent of the phenomenon El Nino causes a cooling of part of the surface waters of the Pacific, influencing the cycle of precipitation and the climate of certain regions of the globe. While its usual duration is two years, the conditions of La Nina persist for the third consecutive year.


This classic seasonal phenomenon (from July to November) is due to the inversion of the trade winds which, laden with humidity, collide with the barrier of the Himalayas. These heavy rains traditionally punctuate agriculture in the region.


The country suffered a severe drought with below-normal rainfall between October 2020 and May 2021 (–36.1%), and between January and April 2022 (–21.6%). The soils no longer absorb the strong and abundant rains.

Soil artificialization

With more than 200 million inhabitants and a population growth rate of 2.4% per year, urbanization is accelerating. Towns sometimes develop in flood-prone areas, rivers are modified and their approaches are concreted. The artificialization of the soil reinforces the phenomenon of runoff.


Pakistan is particularly vulnerable to flooding. In 2010, already, these had caused the death of 2,000 people and caused damage to the tune of 40 billion dollars. Since then, these violent phenomena have become more frequent.

Glacier thaw

With rising temperatures, glaciers are melting and feeding the flow of rivers. High altitude glacial lakes fracture and suddenly release huge amounts of water. Thirty lakes threaten more than 7 million people.

Habitat vulnerability

In precarious housing areas, sanitation systems are often faulty. With the heavy rains, the unsuitable infrastructures do not hold and cause new floods.
