The devastating floods that swept through Buner last week have once again exposed Pakistan’s acute climate vulnerability. Within an hour, an intense downpour unleashed torrents of rain—over 100 to 150 millimetres—turning streams into raging rivers. Entire villages were submerged, homes reduced to rubble, and more than 300 lives lost across KP and the northern areas. What unfolded in Buner is not a freak event but part of a disturbing pattern: Pakistan, despite contributing less than one percent to global greenhouse gas emissions, is among the countries paying the highest price for a warming world.
Over the last fifteen years, the country has endured one climate catastrophe after another. The 2010 “super floods” displaced nearly 20 million people and killed almost 2,000. In the following decade, recurrent monsoon floods across KP, Gilgit-Baltistan, and Punjab disrupted lives year after year, exposing illegal river encroachments and fragile infrastructure. The 2022 nationwide floods pushed Pakistan into the global spotlight—33 million people affected, over 1,700 lives lost, and damages estimated between 30 and 40 billion US dollars. And now, in 2025, the people of Buner have joined this long list of victims, their misfortune another reminder of the climate injustice Pakistan faces.
The Rising Toll of Climate Disasters
Data from the past two decades shows the staggering scale of flood-related losses in Pakistan. In 2010, vast swathes of the country were underwater; agriculture, transport networks, and power systems were crippled, with recovery costs estimated at 10 billion dollars. Between 2015 and 2021, flash floods struck with increasing frequency, often concentrated in KP’s valleys and Punjab’s riverine belts. Though smaller in scale, they cumulatively killed hundreds and displaced thousands. The 2022 floods were unprecedented, not only in their human toll but also in their geographic spread.
Entire districts of Sindh and Balochistan resembled inland seas. Two million homes collapsed, crops over vast acreages were destroyed, and food inflation soared. The 2022 floods caused about 30–45 billion dollars’ worth of damage in addition to thousands of deaths. These numbers are not just statistics—they represent lives disrupted, families impoverished, and development gains washed away. Each flood sets back Pakistan’s progress by years, keeping millions locked in cycles of poverty.
The floods of 2010, 2022, and 2025 are not isolated tragedies but chapters of a single narrative of vulnerability
Why the Disasters Keep Escalating
Science has already explained the mechanics. Warmer air traps more moisture, which releases in sudden, more violent bursts of rain. Pakistan’s glaciers, among the largest outside the polar regions, are melting at accelerated rates, forming thousands of unstable lakes that can burst without warning. Yet natural factors are worsened by human actions: unchecked deforestation leaves slopes bare, unplanned settlements block natural drainage, and illegal constructions choke river corridors.
Buner’s floods represent this lethal combination. A hotter atmosphere delivered extreme rainfall; stripped hillsides accelerated runoff; and settlements built on flood channels left residents directly in harm’s way. Climate change may have loaded the dice, but poor planning turned it into tragedy.
Rehabilitation: More Than Relief
The immediate relief operations—tents, food, and medicines—are vital, but rehabilitation requires a far broader vision. Families need durable housing on safe ground, schools and health centres must be rebuilt to withstand future floods, and farmlands must be restored for livelihoods. Trauma support, particularly for women and children, is equally necessary but often neglected.
Reconstruction cannot follow old patterns of fragile infrastructure. Bridges must be built to new climate-resilient standards, roads elevated and reinforced, and irrigation systems redesigned to cope with heavier, less predictable rains. Such ambitions demand resources far beyond what Pakistan’s provinces or federal budget can bear.
UNFCCC, Global Finance, and Donor Responsibility
This is where international solidarity must come into play. The United Nations Framework Convention on Climate Change (UNFCCC) has created mechanisms precisely for situations like this. At COP27, countries agreed to establish a Loss and Damage Fund, designed to channel resources to vulnerable states suffering from climate-linked disasters. Yet, years later, most of that finance has yet to reach those who need it.
The Green Climate Fund and Adaptation Fund offer further avenues, but Pakistan’s experience has been marred by bureaucratic hurdles and painfully slow disbursements. For communities in Buner, waiting years for project approval is no solution. Donors and global institutions must step up, simplify processes, and recognise that supporting Pakistan’s recovery is not charity—it is an obligation under the principle of climate justice.
Pakistan’s Responsibilities
Global finance is critical, but Pakistan must also confront its domestic failings. Successive disasters have shown that lessons are not being learned. Illegal encroachments continue to block waterways. Forest cover, despite replanting campaigns, remains critically low. Building codes are poorly enforced, and disaster preparedness is underfunded.
To break the cycle, Pakistan must act decisively. A River Protection Act is urgently needed to permanently safeguard floodplains. Watershed management should expand, focusing on restoring forests and stabilising slopes. Early-warning systems must be scaled up, linked directly to communities via mobile alerts and local sirens. Above all, climate resilience must be mainstreamed into national and provincial planning, embedded in the delivery of Pakistan’s climate commitments under its Nationally Determined Contributions (NDCs).
A Test of Global Solidarity
The story of Buner is, in many ways, the story of Pakistan in the climate era: a country that has done little to cause global warming, yet faces its most punishing consequences. The floods of 2010, 2022, and 2025 are not isolated tragedies but chapters of a single narrative of vulnerability.
For the world, the question is clear: will donors and climate institutions live up to their pledges, or will vulnerable nations continue to face disaster after disaster with only piecemeal support? For Pakistan, the challenge is equally stark: will it seize this moment to enforce reforms and build resilience, or will history repeat itself?
The affected people cannot wait for abstract promises. Their lives and futures depend on a global community that matches words with action, and on a government that turns lessons into laws. Climate injustice has already cost Pakistan too much. The time to act is now.
