Global Warming Existential Threat for Pakistan
Global warming severely threatens Pakistan, impacting its environment, economy, and public health. With rising temperatures, Pakistan faces accelerated glacial melting in the Himalayas, which disrupts water supplies crucial for agriculture, drinking water, and electricity generation. Extreme weather events, like floods and heatwaves, have become more frequent, damaging infrastructure, displacing millions, and costing billions in recovery. Pakistan’s agricultural sector is sverely affected by prolonged droughts, and erratic rainfall, which in turn to food security. Public health is also at risk, as rising temperatures facilitate the spread of diseases like malaria and dengue, placing additional strain on fragile healthcare systems. It further creates division over resources between the provinces and the center. Addressing global warming requires Pakistan to adopt sustainable practices, invest in renewable energy, and improve water and agricultural management to build resilience against these far-reaching repercussions.

Far-reaching Impacts of Global Warming on Pakistan
Water Scarcity and Agriculture Productivity
- Melting Glaciers: Pakistan relies on the Indus River system fed by glaciers in the Himalayas. The excessive rise in temperatures is accelerating glacial melting, creating water scarcity and unpredictable water supplies in the long term. It resulted in severe repercussions for the inhabitants.
- Agricultural Disruptions: Agriculture, a major contributor to Pakistan’s economy, is highly sensitive to climate shifts. Erratic rainfall, extreme temperatures, and droughts threaten crop yields and reduce food security.
- Extreme Weather Events
- Floods and Monsoon Variability: Increased frequency and intensity of floods, often attributed to erratic monsoons, have devastating impacts on infrastructure, agriculture, and human lives. Pakistan has been witnessing frequent floods for a decade. The 2022 floods displaced millions and inflicted billions in economic losses.
- Scorching Heatwaves: Rising temperatures are causing extreme heat events in Pakistan, particularly in urban areas like Karachi, leading to health crises, reduced productivity, and increased energy consumption for cooling.
- Public Health Risks
- Disease Spread: Warmer temperatures facilitate the spread of vector-borne diseases such as malaria and dengue, putting strain on an already stretched healthcare system. The capital of Punjab is become the hub of Dengue cases.
- Air Pollution: Climate change compounds air quality issues in urban centers, where warmer conditions worsen smog and respiratory health risks, affecting millions. For a few years, Lahore is among the top three most polluted air quality indexes.
- Economic Instability
- Impact on Livelihoods: Climate change disrupts traditional livelihoods, especially in agriculture and fishing, pushing rural communities into poverty and urban migration, and increasing urban infrastructure pressure.
- Costs of Recovery and Adaptation: Pakistan spends much of its budget on disaster recovery, leaving fewer resources for sustainable development investments. Pakistan has insufficient funds for the full rehabilitation of climate disaster-affected areas. The country is seeking Climate finance for the recovery of flood-affected areas.
Proposed Model of Sustainable Economic Development
Emphasis on Renewable Energy Transition
- Expand Renewable Infrastructure: Investing in solar, wind, and hydropower can reduce dependency on fossil fuels and provide clean energy. Pakistan has a high potential for solar and wind power, especially in Sindh and Balochistan.
- Incentives for Green Investments: Government incentives for renewable energy can attract private sector investment, making green energy more viable.
Promoting Sustainable Agriculture Practices
- Climate-Resilient Crops: Shifting to drought-resistant crops and implementing efficient irrigation techniques (such as drip irrigation) can make agriculture more sustainable and less vulnerable to climate change.
- Soil and Water Conservation: Promoting conservation practices like rainwater harvesting, crop rotation, and soil preservation techniques will help maintain agricultural productivity.
Focus on Urban Planning and Green Infrastructure
- Eco-Friendly Urban Development: Developing green spaces, improving public transportation, and regulating emissions in cities can reduce urban heat islands and improve resilience.
- Smart Building Initiatives: Promoting green building standards, with energy-efficient construction and waste recycling, can significantly cut down urban energy consumption and reduce heat.
Implement efficient Water Management and Conservation
- Efficient Water Usage: Implementing water-saving technologies in industries and agriculture and promoting public awareness campaigns can help manage water scarcity.
- Dams and Reservoirs: Building small dams and reservoirs can help regulate water flow, prevent floods, and store water for dry periods.
Strengthening Policy and Institutional Framework
- Climate adaptation policies: Implementing policies specifically targeting climate adaptation and disaster preparedness will help build resilience across sectors.
- Public-Private Partnerships: Encouraging collaboration between government agencies and private companies can expedite sustainable development initiatives and mobilize resources more effectively.
Conclusion
Implementing this green growth model requires policy shifts, public engagement, and robust financing mechanisms. With a strong emphasis on renewable energy, sustainable agriculture, water conservation, and green urban planning, Pakistan can transition to an economic model that supports both growth and environmental preservation, fostering long-term resilience against the existential threat of global warming. It is high time to take comprehensive measures to mitigate this rising threat until it is too late
