TODAY, countries mark World Wetlands Day with predictable pledges. For Pakistan, it is more than a symbolic date. It is a reminder that some of the country’s most valuable natural assets — its mangroves, lakes, marshes and riverine floodplains — are vanishing quietly, even as climate shocks grow louder. It has now become a question of survival. In a country lashed by floods, heatwaves and cyclones, its marshes and mangroves form a thin, fraying line of defence. Few ecosystems illustrate this urgency better than the mangrove forests of the Indus Delta. Once depleted by reduced freshwater flows, unchecked cutting and coastal pollution, these forests have shown signs of recovery in recent years due to provincial plantation drives. Yet the gains remain fragile. Mangroves are not decorative greenery; they are living infrastructure. They buffer coastal communities against cyclones and storm surges, reduce erosion, store vast amounts of carbon and sustain fisheries that support thousands of livelihoods in Sindh. Beyond the coast, Pakistan’s wetlands are under mounting stress. Urban encroachment, industrial effluent, solid waste dumping and ill-planned infrastructure projects have degraded lakes such as Manchhar and Haleji. Reduced river flows, driven by upstream diversions and erratic rainfall patterns, have further altered fragile ecosystems. The result is a steady decline in biodiversity, including migratory bird populations that once thrived in these habitats.

The paradox is striking: wetlands are among the most effective natural tools for climate adaptation. They absorb floodwaters, recharge aquifers and filter pollutants. In a country repeatedly battered by catastrophic floods, investing in wetland restoration should be central to disaster management planning. Instead, wetlands are often treated as wasteland — convenient sites for dumping, construction or speculative development. Marking World Wetlands Day must therefore go beyond ceremonial seminars. Authorities should strengthen enforcement against encroachment, ensure environmental impact assessments are credible and transparent, and integrate wetland conservation into provincial land-use planning. Equally vital is restoring environmental flows to the Indus Delta so that mangroves can survive in the long term. For Pakistan, protecting its wetlands is a practical defence against climate breakdown, economic insecurity and ecological collapse.
