A solution? Mangroveskere in southern Madagascar, heat dome in North America in June, 2020, one of the hottest years ever recorded... The world is facing an increasing manifestation of climate change and Intergovernmental Panel on Climate Change has recently stated in a study that the impacts of climate disruption will accelerate and become palpable well before 2050. The commitment of the countries of the world to maintain the rise in average temperature at 2°C is no longer sufficient to protect against climate change. Its impacts are the degradation of various coastal ecosystems: loss of marine habitats, erosion and coastal degradation, ocean warming, ... As a result, the services provided by ecosystems are threatened.
What can we do then? Continue the actions that work because there is no miracle solution. Combined actions are needed.
Mangroves can store 3 to 5 times more carbon than terrestrial forests. They therefore mitigate the emission of greenhouse gases, responsible for climate change. This is the eco-systemic function of mangroves, and it works. Sustainable conservation and restoration of mangroves is therefore one of the most effective solutions. WWF and local communities in the Diana and Menabe regions have achieved more than 128 hectares of mangrove reforestation in 2020.
When it comes to the resilience of the world's populations to the consequences of climate change, mangroves continue to be a solution that works. One square kilometer of mangroves can produce up to 2.5 tons of crab with sustainable mangrove conservation measures and a sustainable crab industry. 3000 species of fish live in mangroves. There would be more than 2000 tourist attractions related to mangroves in the world. Moreover, in 2017 a fishing village near Morondava decided to launch a community ecotourism in the heart of which are the mangroves, the main tourist attraction.
Aware of the importance of mangroves, as a natural solution and for the economy, the government, through the Ministry of Environment and Sustainable Development and the Ministry of Agriculture, Livestock and Fisheries, supported by conservation organizations including WWF set up a national commission for integrated management of mangroves in 2016. This was followed by the creation of an Ad Hoc Committee to oversee the development of the National Strategy for Integrated Management of the Mangrove Ecosystem in Madagascar.
Today, these different actors are still meeting to organize together a memorable World Mangrove Day 2021. But beyond the celebration, this momentum should encourage stakeholders to effectively apply these different management tools. Above all, it is high time to finalize the development of the national mangrove management strategy, on which the solutions are based. Then, it will be necessary to translate this strategy and the commitments on actions. Then, start to effectively restore the lost and degraded mangroves of Madagascar; to prove to the rest of the world that we hold one of the effective solutions to avoid the devastating effects of climate change .
