Pakistan’s marine ecosystems in crisis: urgent action needed to combat sea pollution

//

Pakistan, blessed with a 1,046-kilometer-long coastline along the Arabian Sea, possesses a rich and diverse marine ecosystem that is critical to the country’s economy, environment, and food security. This region is facing a critical crisis which must be addressed immediately to curb the incessant environmental and local community damage that they incur daily.

From the bustling commercial hubs of Karachi Port and Port Qasim to the emerging strategic gateway of Gwadar, Pakistan’s coastal and marine resources support millions of livelihoods through fisheries, trade, tourism, and maritime industries. Yet, despite this strategic importance, Pakistan’s seas are facing an unprecedented crisis: rampant pollution that threatens marine life, public health, and economic sustainability.

As an environmental publication with over two decades of dedicated coverage on climate, public health, and ecological issues, Monthly Subh-e-Nau (SN) has long been advocating for marine conservation. In 2005, SN successfully engaged with the then President of Pakistan, General Pervez Musharraf, presenting the landmark “Save the Sea” Project, a pioneering initiative aimed at addressing sea pollution and protecting marine biodiversity. In 2005, an historic meeting was convened at the Governor House, Karachi, chaired by the then Governor of Sindh, Dr. Ishratul Ibad. The meeting resulted in the formation of a committee tasked with developing strategies to curb pollution and promote sustainable marine management. Unfortunately, the committee’s efforts could not produce long-term solutions, and in the years since, the condition of Pakistan’s coastal waters has only deteriorated, exacerbated by rapid urbanization, industrial growth, and weak enforcement of environmental regulations.

The growing menace of sea pollution

Pakistan’s major ports, Karachi Port, Port Qasim, and Gwadar, now rank among the most polluted coastal zones in South Asia. Untreated industrial effluents, municipal sewage, oil spills, plastic debris, and other hazardous wastes are discharged continuously into the sea. These pollutants accumulate in the water and sediments, adversely affecting marine flora and fauna. Studies indicate elevated levels of heavy metals such as mercury, lead, and cadmium in commercially important fish species. Consumption of contaminated seafood poses serious health risks to coastal populations, including neurological and developmental disorders in children, kidney and liver damage, and other chronic diseases.

The ecological consequences are equally severe. Marine species are experiencing population declines, coral reefs and seagrass beds are under threat, and the overall biodiversity of Pakistan’s coastal waters is declining. The pollution not only undermines the natural resilience of the marine ecosystem but also jeopardizes Pakistan’s fisheries sector, which contributes significantly to domestic food supply and export revenue. Fisheries employ over a million people directly, while many more depend indirectly on the sector, making marine pollution an urgent socio-economic issue as well.

Mangrove depletion: A silent crisis

Compounding the problem is the rapid degradation of mangroves along the Sindh and Baluchistan coasts. Mangrove forests are natural buffers against climate change, protecting coastal communities from storm surges, tidal flooding, and soil erosion. They also play a crucial role in filtering pollutants, stabilizing sediments, and providing breeding and nursery grounds for a vast array of marine species. Yet, despite their critical ecological function, Pakistan has lost significant portions of its mangrove cover due to deforestation, land reclamation, and unregulated industrial activities. Restoration and protection of mangroves must be treated as a national priority, not just for environmental reasons, but as a key climate adaptation, climate mitigation and public health measure.

Economic implications of marine pollution

The economic costs of neglecting Pakistan’s seas are profound. Polluted waters reduce fish stocks, threaten aquaculture, and diminish the export potential of seafood products. Tourism and recreational activities along the coast are affected by unsightly and unhealthy beaches, reducing the potential for foreign exchange earnings and local employment. Moreover, industrial pollution and oil spills can lead to costly cleanups and legal liabilities, diverting resources that could otherwise be used for sustainable development. By failing to address marine pollution, Pakistan risks not only environmental degradation but also long-term economic losses and social dislocation.

A call for comprehensive action

Addressing this crisis requires a holistic and multi-pronged approach. In a recent letter addressed to the Honorable Prime Minister of Pakistan, Mian Muhammad Shehbaz Sharif, Monthly Subh-e-Nau outlined a set of actionable recommendations that, if implemented, can reverse the deteriorating condition of Pakistan’s seas and safeguard marine biodiversity for future generations.

• First, a nationwide cleanup of all seaports and coastal waters must be initiated immediately. This entails the removal of solid waste, dredging of contaminated sediments, and the safe disposal of hazardous materials. Parallel to this, stringent monitoring and enforcement mechanisms are needed to prevent the discharge of untreated industrial and municipal waste into the sea. Industries must be mandated to treat effluents to internationally accepted standards, and municipal sewerage systems must be upgraded to prevent untreated sewage from entering marine ecosystems.

• Second, Pakistan must undertake a national mangrove restoration and protection campaign. This requires close collaboration between federal and provincial governments, local communities, non-governmental organizations, and the private sector. Mangrove plantation programs should be prioritized in areas most affected by deforestation, and strict legal protections must be enforced to prevent further degradation. Beyond ecological restoration, this initiative will strengthen coastal resilience against climate change-induced disasters such as cyclones, sea-level rise, and coastal erosion.

• Third, effective inter-institutional coordination is crucial. Climate, maritime, naval, fisheries, and port authorities must work together in a synchronized framework to ensure that regulations are implemented consistently, pollution sources are identified and controlled, and response mechanisms for environmental emergencies are operational.

• Finally, there is an urgent need to revive and empower a national mechanism dedicated to addressing marine pollution. This body should be results-oriented, with clear timelines, defined responsibilities, and accountability measures. Periodic audits and impact assessments must be conducted to evaluate progress and ensure continuous improvement in marine conservation efforts.

• Scientific monitoring, research and development must be systematically conducted for the public and politicians to properly devise evidence-based policies. There is a severe lack of basic understanding of our local ecosystems and without this we cannot develop proper plans for ourselves as well as in the long term, including for our upcoming generations.

Public health and intergenerational responsibility

Protecting Pakistan’s seas is not only an environmental imperative but also a public health necessity. Coastal communities are on the frontlines of exposure to contaminated water and seafood, and failure to act endangers the health of millions. Additionally, safeguarding marine biodiversity and ecological balance is a matter of intergenerational justice: Pakistan’s children and grandchildren deserve a sustainable, productive, and safe marine environment.

Conclusion

Pakistan stands at a critical juncture. The choices made today regarding marine conservation will determine whether the country’s coastal resources are preserved or degraded beyond repair. While challenges are significant, they are not insurmountable. With political will, effective governance, and active engagement of civil society and the private sector, Pakistan can restore its seas, protect marine life, and secure the health and prosperity of its coastal populations.

Monthly Subh-e-Nau calls upon the Honorable Prime Minister, federal and provincial authorities, port and naval administrations, and all stakeholders to prioritize marine conservation as a national agenda. Immediate, coordinated, and sustained action is essential to combat sea pollution, restore marine ecosystems, and ensure a safe and productive coastal environment for generations to come.

The time for debate has passed. The time for action is now. Pakistan’s seas are calling for attention — failure to respond would be a loss borne not just by the present generation but by the future of the nation.
