Yet these so-called “forests of the tide” provide enormous benefits to humanity, especially as essential harbors for biodiversity, as buffers against the destructive power of waves, and as nurseries for coastal and offshore fisheries worldwide. • Mangrove swamps protect coastal areas from erosion, storm surge (especially during hurricanes), and tsunamis. Mangrove Swamps If there are no mangrove forests, then the sea will have no meaning. Often the simplest steps to restoring swamps involve plugging drainage ditches and removing levees .

Conversion of mangroves for coastal aquaculture is the foremost driver of mangrove loss, the report says. In Australia, Bangladesh, Cuba, Suriname, and French Guiana, the extent of loss has been kept to less than 1% over the same period. About 5 to 20% of coastal wetlands (including mangroves) will be lost through sea-level rise by 2080. Mangroves provide rot resistant, high value timber and excellent fuelwood which has been harvested in sustainable silviculture programmes in some countries for over 120 years. New coastal roads that were built to provide access to these hotels have cut off the natural hydrological connections between habitats.”, “Without mangroves, coastal erosion is widespread and beaches are continuously being replenished artificially, a very expensive venture. Limited losses have occurred in East Africa, with only an 8% decline between 1980 and 2005. Planners, scientists, and coastal dwellers have now come to value them as the remarkably diverse and important ecosystems they are. Reduce stormwater runoff. A large part of this mangrove forest is protected by law in both India and Bangladesh to secure the habitat for the region’s unique flora and fauna. That condition is expected to continue into the future as climate change continues warming winters and producing drought conditions. This policy brief was based on the World Atlas of Mangroves (2010), published by Earthscan as an output of a joint project which was primarily funded by the International Tropical Timber Organization (ITTO) through the Japanese Government, and implemented by the International Society for Mangrove Ecosystems (ISME) since 2005 in collaboration with the Food and Agriculture Organization of the United Nations (FAO), UNEP-World Conservation Monitoring Centre (UNEP-WCMC), UNESCO-Man and Biosphere programme (UNESCO-MAB), UNU-Institute for Water Environment and Health (UNU-INWEH) and The Nature Conservancy (TNC). 2012•11•14 Hamilton, Loss of mangroves to fish farms, other development, a poor economic trade-off risking human and environmental well-being. Trends of mangrove loss can be rapidly slowed with good management practices, laws and the establishment of clear frameworks for mangrove ownership, use and management to underpin human activities. In a region where fishing in and around mangroves is a critical activity providing food and income for millions of people, the socio-economic impacts of this conversion have been tremendous,” adds Ms. Van Lavieren, Coastal Zones Programme Officer at UNU’s Canadian-based Institute for Water, Environment and Health (UNU-INWEH). Trends of mangrove loss can be rapidly slowed with good management practices, laws and the establishment of clear frameworks for mangrove ownership, use and management to underpin human activities. Likewise, they slow down tidal water enough so its sediment is deposited as the tide comes in, leaving all except fine particles when the tide ebbs. The United States government began enforcing stricter laws and management programs in the 1970's in efforts to protect and restore these valuable ecosystems. Legislation on state and local levels has been enacted, protecting mangroves from direct human damage. “A growing number of economic valuations are being conducted and most reveal the considerable benefits, even from single services such as fisheries,” says Dr. van Lavieren. NatConnect Foundation officials feel that if the safari comes up, then school and college students could see the mangroves and it would make a huge difference in terms of preserving the biodiversity. Mid-Day is now on Telegram. Mangrove forests serve as highly effective carbon stores and sinks. Mangrove deforestation in Indonesia results in a loss of 190 million metric tonnes of CO 2 annually. In many settings mangroves act as a form of natural coastal defence, reducing erosion, attenuating waves and even reducing the height of storm surges. Set against this is a growing realisation of the social and economic value of mangroves and a remarkable array of restoration efforts in many countries around the world.”. Mangrove forests were once generally dismissed as swampy wastelands. Numerous mangrove restoration projects were instigated after the 2004 East Asian tsunami in the belief that replacing lost mangroves would reduce future Red mangroves have dense roots and are found along coastal edges that face the sea. However, “reversing the trends of mangrove loss and of growing vulnerability of coastal peoples will require a real commitment by governments to develop and implement robust high-level policies,” the report concludes.

The most pronounced losses (over 20%) have occurred in the Asian and Pacific regions, followed by Central America. Losses are being driven by a suite of other human threats as well, however, including over-harvesting and deforestation; agricultural, urban and industrial runoff; oil spills; and poorly managed dredging and coastal development. Better connecting mangrove ecosystems with the role they play in the global carbon cycle and climate system could change the economic calculus for mangroves; The role of mangroves in climate change adaptation and disaster risk reduction should be integrated in local and national adaptation plans; The key role of mangroves as carbon stores and sinks needs to be highlighted in national and international strategies that address climate change; Enhance existing carbon stocks and reverse CO2 emissions by increasing protection and restoration of mangrove ecosystems, and build mangroves into emissions trading and climate change mitigation planning. A mangrove swamp … “There is now a growing awareness of the importance of mangroves and government and community-led efforts are under way to restore or replant mangroves, and to improve legal systems to regulate future use.”. “It shows that when well-managed, mangroves can ensure sustainable yields of products.”, The report notes that around Cancún, Mexico, “a mangrove-fringed lagoon was replaced in just a few decades by high rise hotels and some of the most expensive real estate in the country.

An estimated 38% of global mangrove loss can be attributed to the clearing of mangroves for shrimp culture, while another 14% can be blamed on other forms of aquaculture. [NEW DELHI] Dense mangrove forests growing along the coasts of tropical and sub-tropical countries can help reduce the devastating impact of tsunamis and coastal storms by absorbing some of the waves’ energy, say scientists. According to NatConnect Foundation, it has received a positive response from the Mangrove Foundation and its executive director Virendra Tiwari. Often mangal, or mangle, is used both for the red mangrove and the mangrove forest of which it is a part. The mangroves' massive root systems are efficient at dissipating wave energy. An unprecedented partnership of organizations – from forestry and conservation sectors and from across the United Nations – have released a policy brief drawing on the 2nd edition of the World Atlas of Mangroves (2010). “The variation between countries can be mostly attributed to national policies and legal protection,” says co-author Zafar Adeel, director of UNU-INWEH. Since these estuarine swamps are constantly replenished with nutrients transported by fresh water runoff from the land and flushed by the ebb and flow of the tides, they support a bursting population of bacteria and other decomposers and filter feeders. Re-vegetation programmes are implemented two years after the final felling as required. “Such large-scale conversion has had major negative environmental impacts, including collapses in wild fisheries. "Mangrove safaris do help make people understand the importance of mangroves in protecting the coasts and the environment," he said.
