Heatwaves in Pakistan are not a new phenomenon, but their intensity and frequency have increased alarmingly in recent decades. The heatwaves of 2023 and 2024 saw temperatures crossing 52°C, setting new records and bringing the country to a near-standstill.

### Historical Context of Heatwaves

Historically, the summer months of May to August have always been hot in Pakistan, but recent trends show a significant rise in peak temperatures. The cities of Jacobabad and Sibi are often highlighted in climate reports for recording some of the highest temperatures on the planet.

### Factors Contributing to Extreme Heatwaves

1. **Global Warming**: The overarching cause of rising temperatures globally is the increase in greenhouse gases in the atmosphere, primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes.

2. **Urbanization**: Rapid urbanization in Pakistan has led to the creation of heat islands. Cities like Karachi, Lahore, and Islamabad experience higher temperatures due to concrete structures, asphalt, and reduced vegetation.

3. **Deforestation**: The loss of forest cover reduces the natural cooling effect provided by trees, exacerbating heat conditions.

4. **Agricultural Practices**: Traditional farming methods, such as flood irrigation, can contribute to local humidity levels, intensifying the heat experienced in agricultural areas.

## Impacts of Heatwaves

The extreme heatwaves in Pakistan have far-reaching impacts on health, agriculture, water resources, and the economy. The effects are particularly severe on vulnerable populations, including the elderly, children, and those with pre-existing health conditions.

### Health Impacts

Heatwaves pose significant health risks, leading to heat-related illnesses such as heatstroke, dehydration, and exacerbation of cardiovascular and respiratory conditions. During the heatwave of 2024, hospitals in major cities reported a surge in cases of heatstroke and related ailments.

- **Heatstroke and Dehydration**: Prolonged exposure to high temperatures can overwhelm the body's ability to regulate its temperature, leading to heatstroke. Symptoms include dizziness, confusion, rapid pulse, and in severe cases, loss of consciousness and death.

- **Respiratory Issues**: High temperatures can worsen air quality by increasing the concentration of ground-level ozone and other pollutants, exacerbating conditions such as asthma and chronic bronchitis.

### Agricultural Impacts

Agriculture is a critical sector in Pakistan's economy, employing a significant portion of the population. Extreme heat adversely affects crop yields, livestock health, and overall agricultural productivity.

- **Crop Yields**: High temperatures can damage crops, reduce yields, and lead to crop failure. The heatwave of 2024 severely affected wheat and cotton crops, leading to economic losses for farmers.

- **Livestock**: Heat stress in animals can reduce milk production, weight gain, and overall health, impacting livelihoods dependent on livestock farming.

### Water Resources

Water scarcity is a pressing issue in Pakistan, and extreme heat exacerbates the problem. High temperatures increase evaporation rates, reduce river flows, and deplete groundwater reserves.

- **Glacial Melt**: Pakistan relies heavily on meltwater from glaciers in the Himalayas and Karakoram ranges. Rising temperatures accelerate glacial melt, initially increasing river flows but posing long-term risks of reduced water availability.

- **Irrigation**: The agricultural sector, which depends on extensive irrigation, faces challenges as water sources dry up or become unreliable due to erratic weather patterns.

### Economic Impacts

The economic repercussions of heatwaves are profound, affecting productivity, infrastructure, and healthcare costs.

- **Productivity Losses**: High temperatures reduce labor productivity, particularly in outdoor sectors such as construction and agriculture. Workers are forced to take frequent breaks or avoid work during peak heat hours, leading to economic losses.

- **Infrastructure Damage**: Extreme heat can cause roads to buckle, rail tracks to expand, and power lines to sag, leading to costly repairs and maintenance.

## Government and Community Response

The Pakistani government, along with local communities and international organizations, has been working to mitigate the impacts of heatwaves through various initiatives.

### Emergency Response and Health Measures

- **Heat Action Plans**: Major cities like Karachi and Lahore have implemented heat action plans that include public awareness campaigns, establishment of cooling centers, and distribution of water and oral rehydration solutions.
