Innovative coral transplants restore Tanzania's damaged reefs
A groundbreaking coral reef restoration project in Tanzania's Zanzibar region is breathing new life into damaged marine ecosystems. Led by South African marine biologist Dr Camilla Floros, the initiative aims to combat the devastating effects of coral bleaching caused by intense El Niño events in 1998, 2007 and 2016.
Focusing on the Mnemba House Reef, where coral cover had plummeted to a mere 10% due to human pressure, the team has achieved remarkable success since 2021. They have cultivated and transplanted over 7,100 coral colonies, expanding from an initial five nursery tables to 42, now nurturing nearly 6,000 coral fragments.
In 2023, the project took a significant leap forward by deploying six large artificial structures in consultation with local communities. Onto these, 1,500 nursery-grown coral colonies were transplanted, mimicking natural reefs. This innovative approach not only increases marine habitats but also creates new opportunities for local tourism operators, balancing conservation with economic needs.
A new three-year, $787,721 project funded by CORDAP (Coral Research & Development Accelerator Platform) is set to further amplify these efforts. Plans include the creation of 18 additional artificial structures, expanded coral nurseries, and a focus on identifying and cultivating bleaching-resistant coral species. The initiative also incorporates vital educational and socio-economic elements, engaging local communities and schools in marine conservation efforts.
Dr Floros emphasises the crucial role of local expertise in developing effective, culturally appropriate conservation solutions for the Global South. The project's success lies in its holistic approach, combining scientific research with community engagement and sustainable tourism practices.
As climate change continues to threaten coral reefs worldwide, this Tanzanian initiative serves as a beacon of hope and a model for future conservation efforts. By restoring these vital ecosystems, the project not only preserves biodiversity but also safeguards the livelihoods of coastal communities dependent on healthy marine environments.
