Statement of Intent 1

Site Plan locked. Construction going live.

This marks the start of physical works on the Seagrass Centre.
After months of surveying, planning, and design, we’re now moving from drawings to ground.

The site plan sets out the initial layout, access, boundaries, and core infrastructure that will support research, monitoring, education, and restoration activities moving forward.

It’s a small footprint, but a deliberate one — designed to grow with the work, not ahead of it.

And yes… launching construction on your birthday feels like a pretty good milestone. 🎂🌿

From here on, we build.

The crown-of-thorns starfish is one of the deadliest predators of coral reefs. 🐚⭐ In large numbers, it can wipe out entire reef systems, leaving biodiversity struggling to recover.

The crown-of-thorns starfish, though a natural part of the ocean's tapestry, can be a fierce guardian of the coral reefs it calls home. When they gather in large numbers, these starfish can unintentionally harm the beautiful coral ecosystems, leaving our beloved reefs yearning for a tender touch to help them heal and thrive once more. Let's join hands in cherishing and protecting these vibrant underwater gardens. 🌊💙

Naughty snails munching coral—small grazers, big damage. Nature misbehaving in plain sight! 😈🐌 Watch closely.

The Napoleon wrasse, or humphead wrasse (Napoleon Wrasse), is one of the most recognisable reef fish in East African waters—and one of the most overexploited. Once widespread across the Western Indian Ocean, its decline is closely linked to sustained fishing pressure and weak enforcement.

In Kenya, Tanzania, and neighbouring states, Napoleon wrasse are targeted for high-value export markets. Their slow growth, late maturity, and predictable spawning behaviour make them extremely vulnerable to overfishing, even at low levels of extraction.

Overfishing often occurs with limited oversight. Misreporting, inconsistent regulation, and low enforcement capacity allow population declines to continue largely unnoticed until they are severe.

The loss of Napoleon wrasse has ecological consequences. As large reef predators, they play an important role in maintaining reef balance and resilience. Their removal contributes to reef degradation and reduced ecosystem health.

Despite international protection, regulation alone is insufficient. Protecting Napoleon wrasse in East Africa requires effective enforcement, regional cooperation, and long-term stewardship of coral reef systems.

At Bahari Yetu, we view the decline of this species as a clear indicator of governance gaps in reef fisheries management.

Our Founder recently conducted field assessments in Kilifi, identifying a growing threat to mangrove restoration efforts: the rapid expansion of near-shore fish farming within mangrove landscapes.

As part of the ongoing work of Bahari Yetu, these observations raise serious concerns about how current aquaculture practices are interacting with donor-funded mangrove and blue carbon initiatives.

Fish farming is often promoted as a sustainable livelihood alternative. However, in Kilifi, poorly planned aquaculture development is increasingly overlapping with active restoration zones. Mangroves are being fragmented for pond construction, tidal exchange is being altered, and nutrient-rich effluent is entering systems that rely on stable salinity and sediment dynamics. In several locations, restoration projects are attempting to rebuild ecosystem function while adjacent land-use decisions continue to degrade it.

This contradiction undermines long-term ecological recovery. Reduced seedling survival, compromised carbon sequestration potential, and persistent degradation following pond abandonment are becoming common outcomes. The result is restoration that appears successful on paper but struggles to persist on the ground.

This is not an argument against aquaculture itself. It is a reminder that mangroves are not vacant or expendable land. They are critical coastal infrastructure, supporting fisheries productivity, shoreline protection, carbon storage, and community resilience.

If mangrove restoration and blue carbon projects in Kilifi are to remain credible, aquaculture development must be aligned with integrated coastal planning and clear ecological limits. Without this alignment, restoration funding risks continuously repairing damage created elsewhere in the same system.

At Bahari Yetu, we advocate for coastal development pathways that support livelihoods without sacrificing the ecosystems that sustain them.
