Climate Crisis Deepens in Pakistan: From Agriculture Stress to Heatwaves and Water Challenges

Climate change in Pakistan is no longer a distant risk—it is a present and escalating crisis. From erratic rainfall and flash floods to prolonged heatwaves and water shortages, the country is facing multi-dimensional environmental challenges.

According to the Pakistan Meteorological Department, recent forecasts warn of heavy rains, flash floods, and landslides in northern regions, highlighting the increasing unpredictability of weather patterns. These shifts are not isolated incidents but part of a broader climate trend affecting livelihoods, infrastructure, and national stability.

Agriculture Under Pressure Amid Climate Stress

Pakistan’s agriculture sector, the backbone of its economy, is under severe stress due to climate variability. Experts at the Ayub Agricultural Research Institute emphasize that rising temperatures and erratic weather are accelerating pest attacks on crops.

Climate-smart pest control has emerged as a critical strategy. Integrated Pest Management (IPM), combining biological control and minimal chemical use, is being promoted to reduce environmental damage while maintaining crop productivity.

Meanwhile, the government has set ambitious Kharif crop targets despite ongoing challenges. The Federal Committee on Agriculture has projected:

• Rice production: 9.17 million tonnes
• Cotton production: 9.64 million bales
• Sugarcane: 80.3 million tonnes

However, cotton production has already suffered a significant shortfall due to heat stress, floods, and shifting farming patterns. Experts warn that without climate-resilient strategies, food security could be at risk.

Heatwaves Intensifying Across Punjab

Rising temperatures are becoming a defining feature of climate change in Pakistan. In Punjab, forecasts indicate extreme heatwaves from late April through June.

Temperatures are expected to:

• Rise 4–6°C above normal in some areas
• Reach up to 45–46°C in peak summer

Urban centers like Lahore are particularly vulnerable due to the urban heat island effect, where concrete structures and pollution trap heat.

These conditions not only threaten public health but also impact agriculture, water demand, and energy consumption. Authorities have advised citizens to limit outdoor activities, stay hydrated, and take precautionary measures.

Water Scarcity and Infrastructure Challenges

Water stress remains one of Pakistan’s most pressing climate challenges. Despite some improvements from seasonal rains, irrigation shortages of 15–35% are expected during the Kharif season.

In urban areas, infrastructure upgrades are providing temporary relief. For instance, the Karachi Water and Sewerage Corporation recently restored water supply in parts of Karachi by upgrading the Hub Canal system.

However, these improvements are not enough to offset broader systemic issues such as:

• Aging infrastructure
• Unequal water distribution
• Climate-induced variability in river flows

The launch of a national Water, Sanitation, and Hygiene (WASH) database aims to address data gaps and improve resource allocation, marking a step toward climate-resilient governance.

Climate Finance Imbalance Raises Concerns

A major concern in tackling climate change in Pakistan is the imbalance in climate finance. According to experts linked with the Asian Development Bank, most funding is directed toward mitigation projects like renewable energy.

In contrast, adaptation efforts—such as flood protection, water management, and climate-resilient agriculture—receive significantly less funding despite being critical for vulnerable communities.

This disparity has led to:

• Unequal resource distribution across provinces
• Neglect of high-risk areas like Balochistan and northern regions
• Increased vulnerability of marginalized populations

Experts are calling for reforms such as linking development spending to climate risk assessments and ensuring funds are allocated based on vulnerability rather than institutional capacity.

Health Impacts: Heat and Vulnerable Populations

The health impacts of climate change are becoming increasingly evident, particularly among vulnerable groups. Studies show that extreme heat exposure is linked to rising cases of low birth weight in newborns.

Research involving thousands of participants indicates that:

• Up to 13% of low birth weight cases are linked to heat exposure
• Risks are higher in poorer and hotter regions

Pregnant women, especially in low-income urban areas, face compounded risks due to:

• Limited access to healthcare
• Poor housing conditions
• Lack of cooling facilities

Innovative low-cost solutions—such as solar-reflective paint, ventilation systems, and shaded outdoor spaces—are being tested to reduce indoor temperatures and protect vulnerable populations.

Policy Gaps and Urgent Need for Reform

Despite growing awareness, significant policy gaps remain in Pakistan’s climate response. Disaster management plans often lack targeted strategies for high-risk groups such as pregnant women and small-scale farmers.

Experts advocate for:

• Pre-arranged disaster financing systems like parametric insurance
• Adaptive social protection programs for rapid response
• Stronger coordination between federal and provincial governments

International cooperation is also playing a role. Agreements under the Paris Agreement are enabling Pakistan to access carbon markets and attract green investments.

Conclusion

Climate change in Pakistan is intensifying across multiple fronts—agriculture, water resources, public health, and economic stability. While initiatives such as climate-smart agriculture, infrastructure upgrades, and international partnerships offer hope, they must be scaled up urgently.

Without decisive action, the combined effects of heatwaves, water shortages, and food insecurity could deepen existing vulnerabilities and hinder sustainable development.

The path forward requires:

• Balanced climate finance
• Strong policy implementation
• Community-focused adaptation strategies

Pakistan stands at a critical juncture where proactive measures today will determine its resilience against tomorrow’s climate challenges.
