Key findings of FAO report to be discussed at Uganda meeting on wetlands. Download Mangroves … Asia has the largest area of mangroves, followed by Africa and South America. Research has shown that mangroves account for only 3 percent of global forest cover. Today mangroves are rapidly disappearing (at rates exceeding those of tropical rainforests) due to farming, harvesting for timber and charcoal, freshwater diversion, real estate development, and conversion for tourism. Twenty percent of the world's mangroves lost over the last 25 years: Rate of deforestation slowing, but still a cause for alarm 9 November 2005, Rome - Around 20 percent of the world's mangrove forests have disappeared during the past 25 years as a result of over-exploitation and conversion to other uses, according to a new FAO study. The Global Mangrove Alliance hopes to turn the tide. Mangroves in India are 3 percent of its total geographical area. Only 6.9 percent of mangrove forests are protected by law. The world has lost around 3.6 million hectares (ha) of mangroves since 1980, equivalent to an alarming 20 percent loss of total mangrove area according to FAO’s recent mangrove assessment study, entitled The world’s mangroves 1980-2005. But mangroves are at risk of vanishing forever. C. 500,000.

Threats to mangrove forests and their habitats include: Mangroves grow on both the western and eastern coasts of Africa. Around 50% of the world’s mangroves have likely vanished in the last half-century.

Typically, rainforests are lush, humid, hot stretches of land covered in tall, broadleaf evergreen trees, usually found around the equator. The analysis shows that around 75 percent of the Sundarbans has become greener over the last 30 years and no significant decrease in forest area was found over that time. The total area is nearly 10,000 km2. 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). That's the good news. The available global mangrove databases, compiled using disparate geospatial data sources and national statistics, need to be improved. 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. Here, we mapped the status and distributions of global mangroves using recently available Global Land Survey (GLS) data and the Landsat archive. With this in mind, there is a growing need to understand the factors- both biophysical and societal- that contribute to sustainable mangrove management. Mongabay is a U.S.-based non-profit conservation and environmental science news platform.

Mangrove forests grow where saltwater meets the shore in tropical and subtropical regions, thus serving as an interface between terrestrial, fresh-water and marine ecosystems. Wave energy may be reduced by 75 per cent in the wave's passage through 200 meters of mangrove forests, a very substantial amount once the mangrove has been removed. Kenya’s closed canopy forest cover currently stands at about 2 percent of the total land area, compared to the African average of 9.3 percent and a world average of 21.4 percent. 27%. Introduction. Mangroves are commonly found along sheltered coastlines in the tropics and sub-tropics where they fulfil important socio-economic and environmental functions. 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. As new cities are developed, mangrove forests around the world have felt a great impact not only on their ecosystems health, but also their wave-attenuating capacity. Yet those forests have been cut in half in the past three decades, shrinking from 4.2 million hectares in 1982 to 2 million in 2000. 20% of the world’s mangroves lost since 1980. Mangrove forests and “swamps” are important as spawning grounds and nurseries for marine and freshwater species. A study commissioned by the U.N. Environmental Program (UNEP) reports that one fifth (around 35,500 square kilometers) of the world's mangroves -- forests straddling both land and sea -- have … Mangrove cover has previously been calculated by collating reports from individual countries, say scientists. For example, in Southeast Asia, the rate of mangrove disappearance was around 1% annually during the decades of 1970s and 1980s; however, in recent years, the rates have been reduced to around 0.2% (Friess 2016). Despite the incredible value that these ecosystems provide, mangrove forests are vanishing at an alarming rate and could be wiped out forever.

Africa has the next highest percentage (21%), followed by North and Central America (15%), Oceania (12%), and South America (11%).
