Restoring marine ecosystem services by restoring coral reefs to meet a changing climate future

Restoring marine ecosystem services by restoring coral reefs to meet a changing climate future

The Governments of Mauritius and Seychelles, two small island developing states off the coast of Africa, have accessed a new US$10 million grant from the Adaptation Fund to restore their reef ecosystems. The new six-year project (2020 - 2026), supported through the United Nations Development Programme (UNDP), will protect the island nation’s growing tourism industries – which account for over 30 percent of national GDP and employ approximately half the population in both countries – at the same time ensuring food security for fishers who depend on the reefs to feed their families, and reducing risks from high-intensity storms.

The "Restoring marine ecosystem services by restoring coral reefs to meet a changing climate future" project will develop sustainable partnerships and community-based, business-driven approaches for reef restoration, establish coral farming and nursery facilities, and actively restore degraded reefs. On a regional and global level, the project will improve understanding on how to use coral reef restoration as a tool for climate change adaptation, provide models for sustainable management of reef ecosystems, and build capacity for long-term restoration and management of these precious habitants.

As with the rest of the world – as the result of human-induced climate change, pollution and other environmental impacts – Mauritius has lost its live coral at a highly accelerated rate over the past few decades with as much as 70 percent reduction in live coral cover from 1997 to 2007. In Seychelles, coral cover declined 50 to 90 percent over the last two decades.

Mauritius

Mauritius has taken on international acclaim as a diving and beach destination in recent years. Coastal zone activities, especially tourism, account for 36 percent of GDP in Mauritius, generating US$4.3 billion here each year. According to UNDP, beaches in Mauritius have shrunk by as much as 20 meters over the last few decades due to higher seas and weakened coral ecosystems. The government indicates the connected loss of tourism to the beaches here could cost over US$100 million per year by 2060 if nothing is done. The new project will restore reef habitats in Blue Bay Marine Park, which features a new park center, and research and education facilities, and the South East Marine Protected Area, located off the coast of Rodrigues.

Seychelles

Over 300,000 visitors come to Seychelles every year to explore the beaches and pristine waters. The tourism industry now accounts for 46 percent of the nation’s GDP, about US$600 million per year, with over half the nation employed in tourism. Chronic coastal erosion from increased demand for construction along the coasts, poorly planned coastal flooding that results in regular flooding, destruction of marine and coastal impacts, overfishing and other impacts have taken their toll on the nation’s marine ecosystems. Through the project, coral reef restoration works will be launched at Curieuse Marine National Park, Cousin Special Reserve, Saint Anne Marine National Park and Anse Forbans in the waters off Seychelles.

Project details

Climate change has intensified coral bleaching events and mortality in Mauritius and Seychelles over recent decades. Climate change projections predict that global coral bleaching events will increase in frequency and intensity. Therefore, to reduce the adverse impact of climate change on local communities and coral reef-dependent economic sectors in Mauritius and Seychelles, the proposed project will increase climate resilience at both regional and local levels by implementing coral reef restoration with thermal tolerant corals as adaptation to climate change. The proposed project objective will be achieved through the following outcomes: in Mauritius i) development of a sustainable partnership and community based approach to reef restoration, ii) establishment of coral farming and nursery facilities, iii) active restoration of degraded reefs; in Seychelles, iv) development of a sustainable partnership and business approach to reef restoration, v) establishment of coral farming and nursery facilities, vi) active restoration of degraded reefs; in both countries vii) improved understanding and knowledge management of using coral reef restoration as an adaptation to climate change viii) sharing regionally and globally the experienced learned in sustainable coral reef restoration, and ix) training to build capacity for long-term sustainable coral reef restoration.

According to the United Nations, at least 500 million people worldwide rely on coral reefs for food, coastal protection and livelihoods. UN estimates put the value of reef ecosystems at US$36 billion per year for tourism alone. They are also an essential ecosystem, protecting 25 percent of known marine species and protecting coastal communities from storm surges, rising seas and high-intensity weather events like cyclones.

According to the new UN climate report, hotter and more acidic waters resulting from carbon pollution are killing off the world’s reefs at an alarming rate. With a temperature rise of just 1.5°C, the world will lose about 80 percent of coral reefs, while rises above 2°C will kill off virtually all of the world’s coral reefs.
