The Western Indian Ocean is a treasure trove of marine life. It hosts dugongs, sea turtles, and vast seagrass meadows. These lush underwater gardens help scientists, conservationists, and leaders unite to protect our ocean’s health. Recently, at the Western Indian Ocean Marine Science Association (WIOMSA) Scientific Symposium in Mombasa, Kenya, experts shared insights about seagrass mapping, crucial for conservation efforts.
Seagrass meadows, found along coastlines worldwide except Antarctica, are vital for many marine species. Around one in five of the fish we consume rely on these meadows at some point in their lifecycle. In this region, seagrass provides essential habitats for fish like mullet and rabbitfish, significantly contributing to food security and the livelihoods of coastal communities.
Seagrass plays other important roles too. It protects coastlines from erosion and captures carbon from the atmosphere, helping communities adapt to climate change. Yet, many policymakers and the public overlook this vital ecosystem, mainly because seagrass mapping is still lacking in many areas. Without accurate maps, effective conservation and management become challenging.
The good news? Change is on the horizon. The Pew-supported Large-Scale Seagrass Mapping and Management Initiative (LaSMMI) is creating the first detailed seagrass map and carbon assessment for countries like Kenya, Madagascar, Mozambique, and Tanzania, including Zanzibar. LaSMMI is a collaborative effort involving Pew, WIOMSA, and several universities and research institutions.
This initiative is vital, especially considering recent successes in the Seychelles. This island nation became one of the first to map its seagrass accurately and estimate how much carbon these ecosystems store. This crucial data has helped the Seychelles protect its seagrass meadows as part of its commitment to the Paris Agreement.
LaSMMI not only utilizes satellite technology and on-the-ground expertise but also offers students hands-on research opportunities, fostering a new generation of environmental experts. The goal is to complete standardized seagrass maps by the end of 2026 and to heighten awareness of seagrass conservation at both national and regional levels.
Working together through scientific partnerships and policy initiatives, LaSMMI aims to elevate the importance of these often-overlooked ecosystems. With better data and raised awareness, we can help ensure that the seagrass meadows of the Western Indian Ocean continue to flourish and support millions of lives for generations to come.
