Taking Action to Increase Mangrove Habitat 20% by 2030
by The Global Mangrove Alliance founding members Conservation International, The Nature Conservancy and World Wildlife Fund (Partnership)
The target of the Alliance is to increase the global area of mangrove habitat 20% over current extent by the year 2030. Mangrove forests are some of the world’s most valuable coastal ecosystems. They serve as a transition between marine and terrestrial environments and provide critical protection from the impacts of climate change, often for some of the world’s most vulnerable people, by attenuating wave energy and storm surges, adapting to rising sea levels, and stabilizing shorelines from erosion. Mangrove forests are also an incredible source of carbon sequestration and storage, giving them an important role in climate mitigation. In addition, these ecosystems are essential to maintaining fisheries, improving water quality, and conserving unique biodiversity and cultural identity.

Despite the many benefits that these ecosystems provide, they are being destroyed at an alarming rate, largely due to human led deforestation and clearing. In the past century, 67% of global mangroves have been lost. Restoring and conserving these vital ecosystems is key to sustaining both coastal communities and biodiversity. And because investing in mangroves has such wide-ranging benefits, their protection is a key pathway to meeting the ambitious outcomes laid out in the UN Sustainable Development Goals and the UNFCCC Paris Agreement.

The Global Mangrove Alliance is a commitment from the international community to reverse the loss of critically important mangrove habitats worldwide. Its founding members, Conservation International, The Nature Conservancy and World Wildlife Fund, will build upon the diverse skills and networks each organization brings to amplify existing efforts and drive
increased attention to the critical role of mangroves in coastal systems. With an eye to catalyzing new investments, the Alliance aims to improve land use management and on-the ground conservation, restoration and sustainable use of mangroves. The Alliance will work locally, regionally and globally to secure commitments from our partners, governments, and the private sector to halt and reverse mangrove loss. But we cannot do this alone and the Alliance is actively seeking others to join us in making this commitment and helping to reach our goal.
