Today’s Solutions: October 24, 2021

Three years ago, the coral reef along the Kenyan coastline was almost totally destroyed in some areas. Rising surface sea temperatures had triggered devastating bleaching episodes for the fourth time in less than two decades, and with the whitening of coral came a dwindling of marine life. Overfishing only exacerbated the problem. With as much as 60 to 90 percent of the coral destroyed, the Kenya Marine and Fisheries Research Institute (KMFRI) set out to rehabilitate the degraded coral reefs by working with local communities.

Among the areas targeted was Wasini Island, a tiny strip of land off Kenya’s south-east coast where local women have banded together to show that coral restoration techniques can create sustainable livelihoods for communities that depend on fishing and eco-tourism. One way the Wasini women have been doing this is by raising coral in coral gardens and transplanting them to degraded reef areas, providing new habitats for fish species including jacks, groupers, emperors and sweetlips.

The women of Wasini Island have also been restoring fish populations by cultivating seagrass. Overfishing of certain species, such as triggerfish, had led to the disappearance of seagrass because triggerfish fed on the sea urchins that devoured it. Using gunny bags made of sisal to protect the seedlings and prevent them from getting washed away, the women replanted seagrass seedlings on the ocean floor.

The fruits of these efforts cannot be understated: in addition to providing food, seagrass plays a key role in the overall coral reef ecosystem, providing shelter to juvenile fish after they hatch by shielding them from strong waves until they mature and move into the coral reefs. The work of these Kenyan women has also helped restore large swaths of coral reefs, leading to the return of many marine species such as lobsters and octopuses and boosting ecotourism in the process, which is especially important considering 80 percent of the community relies on it for an income.
