Pakistan is a country of striking contrasts where some of the world’s highest mountains rise in the north while vast deserts and fertile plains stretch across its heart. Yet beyond these dramatic landscapes lies another frontier that is often overlooked: its southern edge, where the land meets the vast expanse of the Arabian Sea.
Along Pakistan’s coastline, the Arabian Sea shapes both geography and identity. From the bustling port city of Karachi to the remote, wind-carved shores of Balochistan, the coast reveals a quieter, more elemental side of the country. Here, rugged cliffs descend into turquoise waters, untouched beaches run for miles without a footprint, and fishing communities live in rhythm with the tides, much as they have for generations.
The Arabian Sea is not merely a boundary; it is a lifeline. It sustains livelihoods through fisheries, connects Pakistan to ancient maritime trade routes, and nurtures diverse marine ecosystems that remain largely unexplored. Beneath its surface lies a world of coral communities, migratory species, and rich biodiversity that holds both ecological and cultural significance.
In Pakistan, the story of the land is incomplete without the sea. It is where desert meets ocean, where silence meets movement, and where the country’s natural beauty unfolds in its most raw and unfiltered form, a reminder that Pakistan is not only a land of mountains, but also a nation deeply tied to the rhythm and mystery of the Arabian Sea.
CHURNA ISLAND
Churna Island stands as one of Pakistan’s most important and quietly remarkable marine frontiers. Located roughly 9 kilometers off the coast near Mubarak Village, west of Karachi, this small, rocky island rises abruptly from the Arabian Sea, its barren surface giving little hint of the life thriving beneath the waterline.
Below the surface, Churna reveals an entirely different world. Its submerged slopes and reef structures support one of the richest marine ecosystems along Pakistan’s coastline. Coral assemblages though modest compared to those of the Coral Triangle, form the backbone of this habitat, sheltering reef fish, crustaceans, mollusks, and larger pelagic visitors. Schools of barracuda and trevally sweep through the currents, while moray eels, nudibranchs, and reef-building corals occupy the quieter crevices. Seasonal sightings of dolphins and even whale sharks elevate Churna from a local dive site to a place of genuine ecological significance.
What makes Churna particularly compelling is its position within a heavily pressured coastal zone. The waters off Karachi are subject to intense shipping traffic, industrial activity, and overfishing. In this context, Churna Island functions as a fragile refuge. An isolated pocket where marine life persists against considerable odds.
Recognizing this ecological value, Churna Island has increasingly been discussed and advocated for as a Marine Protected Area (MPA). While formal protections have been evolving and enforcement remains a challenge, the designation reflects a growing awareness within Pakistan of the need to safeguard its marine resources. The concept of protecting Churna is not just about preserving biodiversity; it is about restoring balance in a system that has long been exploited without sufficient regulation.
As a Marine Protected Area, Churna has the potential to become a model for conservation in Pakistan’s waters. Protection can allow fish populations to recover, coral communities to stabilize, and ecological processes to regain resilience. Just as importantly, it offers a platform for education. Divers, students, and local communities can witness firsthand the value of a living reef system, transforming perception into stewardship.
For a country whose marine ecosystems remain largely underexplored, Churna Island is both a starting point and a symbol. It represents the idea that conservation in Pakistan is not only necessary, but possible if given the attention, respect, and protection that the Arabian Sea has quietly been waiting for.
ASTOLA ISLAND
Astola Island, locally known as Jezira Haft Talar or the “Island of the Seven Hills” lies isolated in the Arabian Sea, about 25 kilometers south of Pasni along Pakistan’s Balochistan coast. It is the country’s largest offshore island, yet remains uninhabited, wind-swept, and almost mythic in its remoteness. Rising as a series of rugged, flat-topped plateaus from the sea, Astola is less a tropical island and more a geological outpost. Harsh, dry, and exposed to the full force of the Arabian Sea.
Geographically, Astola is shaped by tectonic uplift and relentless marine erosion. Its cliffs drop steeply into deep blue waters, while wave-cut terraces and rocky shelves define much of its perimeter. There is no freshwater source on the island, and vegetation is sparse, limited to hardy shrubs adapted to salt and aridity. Yet this starkness above water contrasts sharply with what lies beneath. The surrounding seabed hosts patch reefs, rocky substrates, and sandy pockets that together create a mosaic of marine habitats.
It is precisely this isolation that gives Astola its ecological weight. Free from permanent human settlement and relatively distant from industrial coastal pressures, the island functions as a refuge, a rare stretch of relatively undisturbed marine environment along Pakistan’s coastline. Coral communities here, though not extensive in scale, are ecologically significant, supporting reef-associated fish, invertebrates, and seasonal pelagic visitors. The waters also serve as important habitat corridors for migratory species, including turtles and large fish that move along the Arabian Sea’s coastal systems.
Astola’s importance extends beyond its reefs. The island is a critical nesting ground for green turtles and possibly hawksbill turtles, making it one of the few sites in Pakistan where such reproductive activity occurs with minimal disturbance. Its cliffs and rocky outcrops support seabird colonies, linking marine and avian ecosystems into a single, interdependent system. In this sense, Astola is not just an island, it is a node in a larger ecological network spanning the Arabian Sea.
Recognizing this, Astola Island was declared Pakistan’s first Marine Protected Area, a landmark step in the country’s conservation trajectory. This designation elevates the island from a remote curiosity to a national priority. As a Marine Protected Area, Astola holds strategic importance not only for biodiversity preservation but also for scientific research, climate resilience, and sustainable marine management. It offers a living laboratory where baseline ecological conditions can be studied. Something increasingly rare in heavily impacted coastal regions.
Its strategic value also lies in what it represents for the future. Astola has the potential to anchor a broader network of marine conservation zones along Pakistan’s coast, serving as a benchmark for protection, enforcement, and ecological recovery. With proper management, it can demonstrate how marine ecosystems respond when given space to breathe. How fish stocks replenish, how habitats stabilize, and how natural processes regain their rhythm.
In many ways, Astola Island embodies a quiet truth about the Arabian Sea: that even in a region often overlooked in global marine narratives, there exist places of profound ecological importance. Remote, resilient, and still largely intact, Astola stands not just as Pakistan’s first Marine Protected Area, but as one of its most significant natural assets, holding within it the promise of what marine conservation in the region can become.
PIMEC 2023 & ASTOLA EXPEDITION
I was honored to be invited as a speaker at the Pakistan International Maritime Expo and Conference (PIMEC 2023), a platform that brings together visionaries shaping the future of the region’s maritime domain. In conjunction with the event, I was privileged to be hosted by the Pakistan Navy on a remarkable expedition to Astola Island - Pakistan’s first Marine Protected Area. The journey itself was extraordinary: a flight to Pasni aboard a naval aircraft, followed by deployment to Astola, and a return voyage across the Arabian Sea to Karachi aboard the naval vessel PMSS Basol (P-1071). Alongside this mission, a dedicated team from Marine Conservation Pakistan also participated in the expedition, contributing to the collective effort of exploration and environmental assessment. Beyond the experience, the mission carried purpose. I conducted an underwater survey of one of the country’s most ecologically significant yet least explored marine environments. Witnessing Astola both above and below the surface reinforced the immense potential Pakistan holds in marine conservation and underscored the importance of collaborative stewardship in protecting these fragile ecosystems.
VISIONS OF THE NAVAL CONSERVATION UNIT
From the expedition to Astola, the vision of the Naval Conservation Unit (NCU) ceased to be an abstract proposal and revealed itself as a tangible, necessary reality. What unfolded was not just an exploration of a remote island, but a direct encounter with the immense responsibility and opportunity that lies within Pakistan’s marine domain. Standing on the edge of Astola and descending beneath its waters, it became clear that these ecosystems, though resilient, exist in a delicate balance that demands structured protection, informed intervention, and long-term stewardship.
The NCU emerges from this realization as a natural evolution of capability. The Navy, already equipped with reach, discipline, and operational precision, holds the unique ability to extend its mandate into environmental guardianship. This vision is not about adding another task, it is about redefining purpose. The same systems that secure maritime borders can be adapted to secure marine ecosystems; the same personnel trained for defense can be trained to observe, document, and restore.
What the expedition revealed most clearly is that conservation cannot remain fragmented or reactive. It must be institutional, continuous, and embedded within a framework that allows action at scale. The Naval Conservation Unit represents that framework. A dedicated force where science, training, and field operations converge. Divers become researchers, vessels become platforms for exploration, and missions evolve to include not only surveillance, but ecological assessment and rehabilitation.
Astola, in this sense, becomes more than a destination. It becomes a catalyst. It demonstrates what exists, what is at risk, and what is still possible. The vision of the NCU is to take this singular experience and translate it into a sustained national effort: to establish protected zones, to build data-driven policies, to rehabilitate damaged reefs, and to cultivate a culture of stewardship within and beyond the naval forces.
Ultimately, the Naval Conservation Unit is a vision born from firsthand understanding. It is the recognition that protecting the ocean is not separate from protecting the nation, it is an extension of it. And from the waters of Astola, that vision no longer feels distant. It feels inevitable.
COASTAL COMMUNITY
Mubarak Village, resting quietly along the coast west of Karachi, is a place where the relationship between people and the sea is not philosophical - it is immediate, inherited, and absolute. This is a fishing community shaped by generations of dependence on the Arabian Sea, where knowledge of tides, winds, and seasons is passed down not through books, but through lived experience. Yet beneath this deep-rooted connection lies a growing strain, one that reveals itself not in sudden collapse, but in gradual erosion of resources, of stability, and of certainty.
Through my education initiative, carried out with the local arm led by Marine Conservation Pakistan, the process began not with teaching, but with listening. Understanding the socio-demography of Mubarak Village meant stepping into the rhythm of daily life and observing how livelihoods are structured, how decisions are made, and how the community perceives the changes unfolding around them. Fishing here is not just an occupation; it is the backbone of identity and survival. But that backbone is weakening.
What becomes evident, almost immediately, is the harsh reality of environmental degradation. Overfishing, destructive practices, coastal pollution, and the broader impacts of climate change have begun to alter the very ecosystem that sustains the village. Fish stocks are declining, catches are becoming unpredictable, and the effort required to secure a livelihood is steadily increasing. For many, the sea no longer provides as it once did, yet there are few alternatives available.
This is where education takes on a different meaning. It is not about imposing external ideas, but about bridging understanding and connecting what is happening beneath the water with what is being experienced above it. Through dialogue, workshops, and shared field experiences, the initiative seeks to build awareness of how ecosystems function, how they are being impacted, and more importantly, how they can recover. It introduces the idea that conservation is not a restriction, but a pathway to restoring balance and with it, long-term security for the community.
At the same time, the process is humbling. It reveals that solutions cannot exist without context. Conservation efforts must align with the realities of those who depend on the resource. The goal is not to replace tradition, but to evolve it and empowering the community with knowledge that allows them to adapt, to participate, and to become stewards of their own environment.
In Mubarak Village, the story is not just one of degradation, but of potential transformation. It is a place where the frontline of environmental impact meets the possibility of grassroots change. And through education grounded in respect, collaboration, and shared purpose. There is a growing sense that the future of the reef and the future of the community are not separate narratives, but one and the same.
