When Weather Becomes a Security Threat
Aayza Amir
Islamabad: For decades, national security was largely understood through the lens of traditional threats such as war, territorial disputes, and military rivalries.
Today, however, climate change has emerged as one of the most dangerous non-traditional security challenges confronting the world.
For Pakistan, the crisis is especially alarming because climate change is no longer a distant environmental concern; it is directly threatening economic stability, food security, public health, social cohesion, and national resilience.
Unlike conventional security threats, climate change affects every aspect of human life. It destroys livelihoods, intensifies resource competition, triggers humanitarian disasters, and deepens existing inequalities.
In Pakistan, a country already grappling with developmental constraints, governance challenges, and economic fragility, climate change acts as a “threat multiplier,” magnifying vulnerabilities across society.
What makes Pakistan’s situation particularly unjust is the fact that the country contributes very little to global emissions yet suffers disproportionately from climate impacts. Pakistan accounts for less than 1 percent of global greenhouse gas emissions.
By comparison, China contributes nearly 30 percent, the United States around 14 percent, the European Union approximately 7–8 percent, and India nearly 7 percent. Pakistan’s per capita emissions remain among the lowest globally, estimated at around 1 metric ton per person annually, compared to more than 14 metric tons in the United States and 7–8 metric tons in China.

Despite this minimal contribution to global warming, Pakistan stands among the world’s most climate-vulnerable countries.
The devastating floods of 2022 exposed the scale of this vulnerability. Nearly one-third of the country was submerged, more than 33 million people were displaced, and economic losses exceeded $30 billion. Yet the crisis did not end there.
In 2025 and 2026, Pakistan continues to face increasingly frequent and severe climate-related disasters, including extreme heatwaves, irregular monsoon patterns, glacial lake outburst floods (GLOFs), and prolonged droughts. In some regions, temperatures have crossed 50°C, posing serious risks to human health and economic productivity.
The agriculture sector, which supports millions of livelihoods and remains central to Pakistan’s economy, is particularly under threat. Changing rainfall patterns, water shortages, and rising temperatures are reducing crop yields and increasing food insecurity.
Rural communities dependent on farming are increasingly vulnerable to poverty, displacement, and economic uncertainty. Climate change is therefore not merely an environmental issue; it is also a human security crisis.
Water insecurity further intensifies the challenge. Pakistan is rapidly approaching water scarcity, with per capita water availability declining sharply over the decades.
Accelerated melting of Himalayan glaciers may temporarily increase river flows, but in the long run it threatens severe water shortages for irrigation, drinking water, and hydropower generation. In a country where agriculture depends heavily on the Indus River system, the implications for economic and social stability are profound.

Urban areas are equally vulnerable. Cities such as Karachi and Lahore are increasingly exposed to deadly heatwaves, urban flooding, and hazardous air pollution. Poor urban planning, inadequate drainage systems, and expanding informal settlements have made climate impacts even more severe for low-income communities. Climate change, therefore, is not only an environmental challenge but also a question of inequality and social justice.
Importantly, Pakistan’s climate crisis cannot be separated from global politics and international responsibility. Climate change is a cross-border phenomenon.
Emissions produced by industrialized nations are contributing to glacial melting in the Himalayas, sea-level rise in coastal areas of Sindh, and increasingly unpredictable weather patterns across South Asia. Countries like Pakistan are paying the price for a crisis largely created elsewhere.
The economic consequences are equally severe. Climate disasters destroy infrastructure, reduce agricultural productivity, disrupt trade, and force governments to divert scarce resources toward relief and reconstruction efforts.
Studies suggest Pakistan could lose up to 9–10 percent of its GDP by 2050 if climate impacts continue unchecked. Such losses could undermine development gains, increase unemployment, and intensify political instability.
Addressing climate change as a non-traditional security challenge requires both national commitment and global cooperation. Domestically, Pakistan has introduced several important initiatives, including the Ten Billion Tree Tsunami Programme, revised Nationally Determined Contributions (NDCs), and renewable energy policies aimed at reducing dependence on fossil fuels.
However, limited financial resources, technological gaps, and governance challenges continue to hinder effective implementation.

At the international level, developed countries must fulfill their climate finance commitments, particularly the promised $100 billion annually for developing nations. Vulnerable countries like Pakistan require significant support for adaptation, disaster preparedness, renewable energy transition, and climate-resilient infrastructure.
Technology transfer mechanisms must also be strengthened to help developing states adopt clean energy systems, climate-smart agriculture, and sustainable water management practices.
Equally important is the issue of climate justice. Major emitters must adopt far more ambitious emission reduction policies, recognizing that their actions have direct consequences for vulnerable populations worldwide.
Global initiatives on “loss and damage” compensation are also essential because countries like Pakistan are suffering irreversible losses despite contributing minimally to the crisis.
Regional cooperation can further strengthen resilience.
South Asian countries face similar climate threats, including glacier melt, floods, heatwaves, and water stress. Cooperative frameworks for water management, disaster response, and information sharing could reduce risks and improve preparedness across the region.
International institutions such as the United Nations and the World Bank must also play a more active role in supporting vulnerable states through equitable financing and sustainable development initiatives.
Ultimately, climate change represents one of the greatest security challenges of the 21st century for Pakistan. It threatens not only the environment but also economic stability, human security, governance, and social cohesion. Pakistan’s experience highlights a fundamental injustice of the global climate crisis: those who contribute least often suffer the most. Without serious global action and sustained national commitment, climate change will continue to deepen vulnerabilities and reshape the security landscape for Pakistan and many other developing nations.
