Heatwaves in Pakistan And India – Causes, Effects, Solutions

A heat wave is a two-day or longer stretch of exceptionally hot weather. Temperatures must be above the historical norm for a certain location to be termed a heat wave. A heat wave is a result of high-pressure arrival in a region, in which air from the atmosphere’s highest layer is drawn towards the ground, as a result, it becomes warm and compressed. This high warm pressure makes it difficult for other weather to move in an area so that’s why heat waves remain in a region for several days. Harsh sunlight that further heats the system. All these factors involve producing high temperatures and causing heat waves.

In Pakistan and its neighboring country India, an estimated 90 deaths occurred due to heatwaves in 2022. It also caused a glacial outburst in northern Pakistan and fires in India’s forest. India’s crop yields were reduced by the heat. According to India’s Meteorological Department, several monitoring stations reported temperatures ranging from 45°C to 50°C. This is reported after a heat wave in late April and early may during which temperature reached 43-46°C. In Pakistan temperature reached 50°C. According to Pakistan’s Meteorological Department, the mid-day temperature of the swath of the nation was 5-8°C above average. Water supply, agriculture, and human and animal health all suffered as a result of the hot, dry weather.

CAUSES OF HEATWAVES IN PAKISTAN AND INDIA

1. Climate Change

Climate experts discovered that the heatwave was around 30 times more likely as a result of human-caused climate change. According to experts, climate change played a part in boosting the risk of the spring 2022 heat wave in India and Pakistan.

2. Green House Gases and Global Warming

According to scientists, the buildup of greenhouse gases in the atmosphere is contributing to India and Pakistan’s rising temperatures. The catastrophic heat wave that has engulfed most of Pakistan and India this spring has become hotter and more likely to occur as a result of global warming.

3. Environmental Degradation

The main causes of Pakistan’s continuous heatwaves are deforestation, carbon emissions, and pollution. As much as humans require a healthy environment to thrive, our activities have proven to be hazardous to our ecosystems.

4. Urban Heat Islands

The fact that cities have become concrete jungles that absorb and radiate more heat causing them to become Urban heat islands is not really helping with the heat waves. Heat waves seem more severe in metropolitan cities due to more concrete, asphalt roads and close to none greenery.

5. Urbanization

More urbanization means bigger cities, more houses, more roads and more concrete to build all of this and lesser trees – all of which increase the impacts of heat waves and make them worse. To learn more about urbanization, check out: Urbanization – Causes, Effects, and Solutions

 

EFFECTS OF HEATWAVES IN PAKISTAN AND INDIA

1. Health Crisis

Heatwaves have caused serious health risks and triggered public health emergencies. Heat strokes and heat exhaustion are caused by prolonged heat exposure, as are many respiratory and cardiovascular disorders.

2. Effect on Economy

Heatwaves also have a negative impact on several areas of the economy. For example, the loss of working days has a significant impact on the livelihood of poor and marginal farmers.

3. Reduce Agriculture Yield

High temperatures caused due to heat waves have a detrimental influence on crop development which is an essential element for a nation. It is due to disturbance in soil moisture level, accelerate photosynthesis change in respiration, all these factors affect plant growth and development.

4. Effect on Life under the Sea

Heatwaves have a serious negative impact on the life under the sea as even the slightest changes in the temperature of sea water can have huge implications. For more information, please read: Heatwaves Are Killing Off Sea Life In Billions – Destroying The Ecosystem

5. Wildfires, Forest fires and Bush fires

Heatwaves are directly linked to wildfires in forests which themselves are terrible for the environment, human population and animal/plant species of that area. To know more about this, check out: Global Heat Wave and Wildfires – Causes, Effects, Solutions

 

WHAT WE CAN DO TO REDUCE HEATWAVES IN PAKISTAN AND INDIA?

1. Tree Plantation

Trees are not only known to provide shade they are also responsible to make the air clean and cool. Some trees such as Ficus religiosa release oxygen during the night also, so plant these trees more and more.

2. Reflective or Lighter Roofs or Wall Paint

Roofs or wall paint play an important role in decreasing the hotness so replace darker places with light and reflective materials.

3. Make Use of Energy-Saving Appliances and Equipment.

Using energy-efficient appliances and equipment in your house can assist to reduce the stress on the electric grid during heat waves, guaranteeing a more consistent supply of electricity in your neighborhood.

CONCLUSION:

In summary, heatwave is caused by high pressure in a location, in which air from the highest layer of the sky is dragged towards the ground, becoming heated and compressed. Humans-caused climate change has a major role in causing heat waves. Take care to protect yourself from the effects of hot weather induced by heat waves.
