Nice, France, 11 June 2025 The UN Environment Programme (UNEP) and the Food and Agriculture Organization of the UN (FAO) have named the first World Restoration Flagships for this year, tackling pollution, unsustainable exploitation, and invasive species in three continents. These initiatives are restoring almost five million hectares of marine ecosystems an area about the size of Costa Rica, which, together with France, is hosting the 3rd UN Ocean Conference.
The three new flagships comprise restoration initiatives in the coral-rich Northern Mozambique Channel Region, more than 60 of Mexicos islands and the Mar Menor in Spain, Europes first ecosystem with legal personhood. The winning initiatives were announced at an event during the UN Ocean Conference in Nice, France, and are now eligible for UN support.
After decades of taking the ocean for granted, we are witnessing a great shift towards restoration. But the challenge ahead of us is significant and we need everyone to play their part, said Inger Andersen, Executive Director of UNEP. These World Restoration Flagships show how biodiversity protection, climate action, and economic development are deeply interconnected. To deliver our restoration goals, our ambition must be as big as the ocean we must protect.
The World Restoration Flagship awards are part of the UN Decade on Ecosystem Restoration led by UNEP and FAO which aims to prevent, halt, and reverse the degradation of ecosystems on every continent and in every ocean. The awards track notable initiatives that support global commitments to restore one billion hectares an area larger than China by 2030.
The Northern Mozambique Channel
This small region boasts 35 per cent of the coral reefs found in the entire Indian Ocean and is considered its seedbed and nursery. Agricultural run-off, overfishing, and climate change threaten this economically and ecologically important stretch of ocean.
Comoros, Madagascar, Mozambique, and Tanzania are already working together to manage, protect, and restore almost 87,200 hectares of interconnected land- and seascapes, benefitting both nature and people.
Actions undertaken today to maintain it include restoration of blue and green forests by creating interconnected restoration corridors, mangroves, and coral reef ecosystems, and improving fisheries management. These efforts, championed by the NGO World Wide Fund for Nature (WWF) and UN agencies alike, encompass multiple levels and sites, spanning both land and seascapes.
With adequate financing, 4.85 million hectares are expected to be restored by 2030. This is expected to improve communities well-being and socio-economic development, including a 30 per cent increase in household income in target areas, and create over 2,000 jobs and 12 community-based enterprises, while integrating indigenous practices.
Madagascars mangroves already store more than 300 million tonnes of carbon dioxide equivalent (COe), comparable to the annual electricity use in over 62 million homes in the United States. The restoration is expected to increase the capacity of the four countries involved to absorb CO and help tackle climate change.
Mexicos seabird islands
Recognized worldwide as vital hotspots for biodiversity, particularly for being home to one-third of the worlds seabird species, the Mexican islands had long suffered the negative impacts of invasive species.
Then, 26 years ago, Mexicos National Commission for Natural Protected Areas (CONANP) and the civil society organisation Grupo de Ecologa y Conservacin de Islas (GECI) launched an ambitious, comprehensive ecological restoration program, in collaboration with partners from government agencies, civil society, academia, and local communities.
Efforts include removing 60 populations of invasive species and restoring seabird colonies, as well as forest landscape restoration. Coupled with implementing biosecurity protocols, the comprehensive programme restores the islands endemic richness and supports local island communities.
Thanks to restoration efforts, 85 per cent of formerly extirpated seabird colonies have returned to the islands, including species at risk of extinction. The initiative will complete the restoration of over 100,000 hectares by the end of the decade equivalent to almost a million hectares of continental land in terms of biodiversity value encompassing almost 100 islands, and protecting over 300 endemic species of mammals, birds, reptiles, and birds.
An enduring relationship with local communities ensures their involvement in the initiative and their benefits: enhanced resilience facing extreme weather events, sustainable fisheries, and ecotourism.
Spain: The Mar Menor lagoon
With its famously transparent water, the Mar Menor lagoon is essential to the regions identity, local tourism, small-scale fishing and unique flora and fauna, including water birds. Surrounded by one of Europes key agricultural regions, it is the continents largest saltwater lagoon, and its biodiversity has successfully adapted to conditions of extreme temperatures, high salinity, and low levels of nutrients.
However, unsustainable agricultural activity with tons of nitrates discharged daily, as well as other polluting land and marine activities, have led to the lagoons rapid degradation, including the emergence of damaging algal blooms. Associated economic losses have surpassed EUR 4 billion, according to the Bank of Spain.
A positive turn came when over half a million citizens mobilized in response to episodes of green soup and fish kills and supported a Popular Legislative Initiative to make the Mar Menor a legal entity with rights. Actions were also promoted from the justice system to demand the application of environmental liability regulations and possible criminal liability into the pollution.
The Spanish Government launched an ambitious intervention through the Framework of Priority Actions to Recover the Mar Menor (MAPMM), aimed at restoring the natural dynamics and solving the problem from the source, articulated in 10 lines of action and 28 measures, by creating wetlands, supporting sustainable agriculture, constructing a wide green belt around it, cleaning up abandoned and polluted mining sites, improving flood risk management, increasing its biodiversity, and sustaining social participation.
The total area targeted for restoration amounts to 8,770 hectares, representing 7 per cent of the entire basin flowing into the Mar Menor. This area would support Spain's climate change objectives, including its overall national target of restoring 870,000 hectares by 2030. For one of the proposed interventions, the Green Belt, it is estimated to absorb more than 82,256 tonnes CO by 2040 the equivalent of the annual greenhouse gas emissions from almost 14,000 people in Spain.
World Restoration Flagships are chosen as the best examples of ongoing, large-scale and long-term ecosystem restoration by a group of ecosystem restoration experts from the UN Decade on Ecosystem Restorations network. Selection follows a thorough review process with 15 criteria, embodying the 10 Restoration Principles of the UN Decade.
In 2022, the inaugural ten World Restoration Flagships were recognized as part of the UN Decade on Ecosystem Restoration, followed with the recognition of seven initiatives in 2024.
