They stretch into India, Burma, and south-east Asia. Mangroves in India are 3 percent of its total geographical area. About 90 percent of the mangrove forest cover is found in developing countries, but is nearing extinction in 26 countries. There is 13% less mangrove forest around the world than thought. Typically, rainforests are lush, humid, hot stretches of land covered in tall, broadleaf evergreen trees, usually found around the equator. 27%. The new survey confirms that most mangroves are confined to the tropics and sub tropics and the largest percentage of mangroves is found between 5º N and 5º S. (Ilka C. Feller/Smithsonian Institution, made possible by LightHawk) Despite the appeal of quick financial gain, shrimp farming has hidden, long-term costs. Our study confirms earlier findings that the biogeographic distribution of mangroves is generally confined to the tropical and subtropical regions and the largest percentage of mangroves is found between 5° N and 5° S latitude. Mangroves also provide ideal locations for aquaculture, which is currently “the fastest growing food-producing sector in the world”, though often mangrove forests are destroyed for this purpose. For comparison, the world's area of mangrove forests has been reduced by about 35% on a worldwide scale since the 1980s, and 2.1% of the existing worldwide mangrove area is lost each year. More than 35% of the world’s mangroves are already gone. Approximately how many hectares of Mangrove forests can be found around the world? These initiatives have helped China's mangrove forest area increase from 22,000 hectares in 2000 to around 29,000 hectares in 2019, making the country one of the few in the world to log a net increase. Mangrove forests, consisting of multiple taxa of tropical macrophytes, are distributed mainly in tropical and subtropical regions of the world [1,2,3].The upper latitudinal limits of global distribution, extending into the temperate regions, are characterized by decreased abundance, reduced species diversity, and decreased tree vigor, growth, and biomass (Figure 1). Mangroves are salt-tolerant forest ecosystems commonly found along sheltered coastlines, in deltas and along river banks in the tropics and sub-tropics. Mangrove forests, consisting of multiple taxa of tropical macrophytes, are distributed mainly in tropical and subtropical regions of the world [1,2,3].The upper latitudinal limits of global distribution, extending into the temperate regions, are characterized by decreased abundance, reduced species diversity, and decreased tree vigor, growth, and biomass (Figure 1). More than a third of the world’s mangroves are believed to have disappeared between 1980 and 2000, mostly due to the rise of industrial shrimp farming and coastal development. Mangroves today cover around 15 million hectares (ha) worldwide, down from 18.8 million ha in 1980, according to the study. It is characterized by low tree diversity, almost exclusively mangroves, with a low broken canopy. There are 15.9 million hectares (over 60,000 square miles) of mangrove forests in the warm waters of tropical oceans all over the world. Mangroves are found in more than 120 countries and territories around the world, but the UN agency noted that close to half of the total mangrove area is found in just five countries: Indonesia, Australia, Brazil, Nigeria and Mexico. Thailand has lost 84 percent of its mangroves, the highest rate of mangrove loss of any nation, while the Ivory Coast, Guinea-Bissau, Tanzania, Mexico, Panama, Malaysia, Myanmar, Pakistan, and the Philippines have each lost more than 60 percent of their mangrove forests. In some places, such as Senegal, virtually … This was the case during the 2004 tsunami in Asia where evidence indicates that where extensive areas of mangroves existed, coastal villages suffered less damage. Mangrove forests and “swamps” are important as spawning grounds and nurseries for marine and freshwater species. The largest mangrove forest in the world is Sundarban Mangrove Forest. Threats to mangrove forests and their habitats include: An estimated 75 percent of commercially caught fish spend some time in the mangroves or depend on food webs that can be traced back to these coastal forests. Despite these clear benefits, since 1980 the world has lost approximately 20 percent of its mangrove forests. Fifty percent of the world’s mangroves have disappeared in the past half-century, victims of rising sea levels; oil spills and other pollution; demand for timber; and clearing to make way for shrimp and crab fishing, coastal infrastructure, and urban expansion. These forests provide at least US$1.6 billion each year in ecosystem services. With this in mind, there is a growing need to understand the factors- both biophysical and societal- that contribute to sustainable mangrove management. Here, we mapped the status and distributions of global mangroves using recently available Global Land Survey (GLS) data and the Landsat archive. Where recent information was unavailable (about 3.5 percent of the total mangrove area), the extrapolation to Year 2000 was based on the overall forest change rate as reported in the Global Forest Resources Assessment 2000 (FAO 2001) applied to the latest reliable estimate. Main conclusions We report that the remaining area of mangrove forest in the world is less than previously thought. B. B. However, mangroves have been heavily impacted by degradation and deforestation, with 20%–35% of global mangrove 275,000. The bad news: Mangroves face numerous threats — 35% were lost between 1980 and 2000, and since the turn of the 21st century almost 1 in 50 of the remaining mangrove forests has been cut down. Every day, Mongabay reporters bring you news from nature’s frontline. Home to many species. 65%. ... mangrove forests have vanished around the world? Mangroves once covered much of the world’s tropical coastline, but half of the mangrove forests have been lost in the last half century, according to … 7. Fifty percent of the world’s mangroves have disappeared in the past 40 years, according to UNESCO, and continue to be destroyed and degraded by about 1% per year. “More countries are now recognizing the importance of mangroves and are making an effort to conserve and better manage them,” said Mette Løyche Wilkie, a mangrove expert at FAO. Mangroves constitute only 0.5 percent of forest area worldwide, but millions of people depend on them for food, income and protection of coastlines against erosion. It is prepared by FAO in collaboration with mangrove specialists throughout the world and is co-funded by the International Tropical Timber Organization (ITTO). A. More than a third of the world’s mangroves are believed to have disappeared between 1980 and 2000, mostly due to the rise of industrial shrimp farming and coastal development. Mangroves around the world are vanishing at an alarming rate. Despite their wide-ranging benefits and importance, mangroves are being destroyed and degraded at an alarming rate. The Global Mangrove Alliance hopes to turn the tide. A mangrove is a shrub or small tree that grows in coastal saline or brackish water.The term is also used for tropical coastal vegetation consisting of such species. Indonesia, a country of 17,000 tropical islands, has by far the largest mangrove forest cover, followed by Brazil, Malaysia, Papua New Guinea and Australia.
