Reimagining the Ocean Starts on Land

This World Oceans Day calls us to reimagine a better future for the ocean. For cities and communities, building ocean resilience starts with how land is planned, water is managed, waste is controlled, infrastructure is designed, and how people understand their relationship with the sea.

While the ocean may feel distant from daily urban life, the heaviest pressures it faces begin on land. Pollutants move through streets, drainage networks, construction sites, and wastewater systems before reaching the coast.

To reimagine our relationship with the ocean, we must also reimagine the systems that connect land and sea.

What Reaches the Sea Is Shaped Upstream

What reaches the sea is shaped long before water arrives at the coast. This is where environmental planning serves as the first line of defense. Rather than managing pollution after the fact, strategic planning acts as a proactive safeguard—identifying where development pressures could affect sensitive marine ecosystems before projects begin. By understanding these land-to-sea connections early, we can protect natural buffers, maintain critical drainage corridors and design growth away from vulnerable areas.

Racha Abou Chakra, Environmental Planning Principal, sees early coordination as key to closing governance gaps that allow impacts to go unmanaged.

“Tools such as strategic environmental assessment, Geographic Information Systems (GIS), and coastal habitat surveys at early project stages can help pinpoint the most effective intervention points.”

Infrastructure Makes Prevention Practical

Where environmental planning anticipates and avoids risks, civil infrastructure steps in to manage the physical realities of urban life. It acts as the first line of physical prevention, translating environmental strategy into daily operational defense. Maher Habanjar, Water and Environment Senior Director, emphasizes that stormwater and wastewater systems play a critical role in intercepting pollutants before they reach rivers, seas, and oceans.

“Properly designed infrastructure captures litter, sediments, nutrients and contaminants before they reach shorelines, while advanced wastewater treatment prevents harmful discharges into receiving waters.”

By integrating resilient drainage networks with nature-based solutions, engineered systems can physically catch and treat runoff, reducing land-based threats long before they can impact coastal ecosystems.

Coastal Infrastructure Shapes the Marine Environment

At the point where land meets sea, the connection becomes undeniable. Coastal infrastructure affects and is affected by marine conditions. Outfalls, reclamation works, lagoons, wharfs, and jetties all influence how water moves, how pollutants disperse, and how shorelines evolve over time.

Dr. Ramy Marmoush, Director of the Heavy Civil Sector, highlights the high stakes of these coastal designs: “When we design infrastructure at the coast, we must think beyond the structure itself. The choices we make on land directly affect what happens in the water. Outfall structures are a clear example: where they are placed, how they are sized, and how far they reach offshore can determine whether pollutants disperse safely or build up and damage the surrounding marine environment.”

The same principle applies to land reclamation and hard coastal infrastructure. Without proper circulation, lagoons and basins can suffer from stagnant water, low dissolved oxygen and harmful algal growth. Similarly, wharfs and jetties can inadvertently trigger severe shoreline erosion if sediment dynamics are not properly understood. This is why marine engineering must consider coastal dynamics, water circulation, sediment balance and long-term ecological impact from the earliest design stages.

Ocean Resilience Requires Connected Systems

Reimagining a better ocean future requires looking beyond the shoreline. It means rethinking the systems of urban growth, waste management, and infrastructure design.

For K&A, ocean resilience cannot sit confined to a single discipline. It depends on connected, collaborative decisions spanning planning, environment, water, wastewater, infrastructure and marine engineering.

A better ocean future is protected at sea; it is also planned, designed, and managed on land.
