Wetlands could be one of the solutions to the climate change we are facing. A world day is even dedicated to them on 2 February, since 1972 and the Ramsar Convention. This year's theme was "Wetlands and water" and highlighted the importance of protecting them.
Ecosystems that meet our needs
Wetlands cover a range of ecosystems, from marshes to mangroves. They are home to unique flora and fauna that distinguish them from other ecosystems on the planet. In fact, wetlands are home to 12% of the animal species on Earth and, on a global scale, their surface area exceeds that of Greenland.
However, they do not escape the pression of human beings. According to the United Nations Framework Convention on Climate Change (UNFCCC), The exponential growth of the world's population, urbanisation, pollution, intensive agriculture and other human activities have caused them to lose 35% of their surface area between 1970 and 2015. This rate, which has accelerated since the 2000s, is three times higher than the global average deforestation rate.
Yet wetlands are indispensable to us, not only for their priceless biodiversity, but also because they participate in climate regulation. Some of them absorb up to 30% of atmospheric carbon, twice as much as the world's forests. Others, such as coastal wetlands, have a major interest in retaining water and thus help to regulate its rise, while acting as a natural barrier to waves and even tsunamis.
Almost 90% of the world's wetlands have been lost since the 1700s... urgent action is needed!
Planète Urgence acts in favour of wetlands
CIt is particularly with this last point in mind that Planète Urgence has decided to develop its reforestation actions in Indonesia, first on the island of Sumatra, then on the island of Borneo. Indeed, in 2004, this South-East Asian country faced the worst tsunami in history.
One striking finding was that if economic activities in some coastal areas had been managed sustainably, the extent of the damage could have been mitigated.
Indeed, in Indonesia, the massive deforestation of mangroves is closely linked to aquaculture activities. Yet this ecosystem acted as a barrier to this type of natural disaster.
Thus, the restoration of the mangrove is particularly essential.
Planète Urgence has been supporting rural populations in developing countries in the protection and sustainable use of their environment since 2007 through the following programme Environment & Development. After working in Mali and Haiti, the association is currently working in Indonesia, in Madagascar and in Cameroon, as well as on new projects in favour of ecosystems and communities particularly vulnerable to climate change and deforestation.
Throughout the year, we set up the operation 1€=1 tree. For one euro paid, you contribute to the planting of a tree and receive your planting certificate. Discover our different projects and take part in reforestation by making a donation!
