A 2018 study calculated that the world's mangrove forests suck up more than 6 billion tons of carbon a year. 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. Long term survival of mangroves is at great risk because of fragmentation of the mangroves. 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. 65%. 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. In just the last decade, at least 35 percent of the world's mangroves have been destroyed. Here, we mapped the status and distributions of global mangroves using recently available Global Land Survey (GLS) data and the Landsat archive. 6. “Other studies suggest that the number of Sundarbans mangroves has remained stable or decreased very slightly over the last few decades, and this is also what we found,” said Awty-Carroll. 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. Most of the closed-canopy forests in Kenya are montane forests that are also the nation’s water towers. Twenty percent of the world’s mangroves lost over the last 25 years: Rate of deforestation slowing, but still a cause for alarm Although human pressures are a major threat, little is known about the governance conditions that facilitate long-term conservation and restoration […] 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. 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 present chapter deals with the current status of research on mangrove-inhabiting fauna, threats and conservation in India. A. Asia has the largest area of mangroves, followed by Africa and South America. 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.

The unexpected decline in this unique coastland habitat is revealed by the first global satellite survey of mangroves, which grow in intertidal regions of the tropics and subtropics. In the past, many governments actively encouraged such development of mangrove areas in order to strengthen food security, boost national economies and improve living standards. How many people were killed in the boxing day tsunami? Mangrove forests are globally recognized as highly carbon-rich tropi-cal ecosystems that provide a range of critical economic and ecolog-ical services to surrounding coastal populations (Barbier et2011; al., Donato et al., 2011). 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). Mongabay is a U.S.-based non-profit conservation and environmental science news platform. Approximately 75 percent of the world’s mangrove forests are found in just 15 countries. Mangroves help prevent and reduce coastal erosion, providing nearby communities with protection against the effects of wind, waves and water currents. With this in mind, there is a growing need to understand the factors- both biophysical and societal- that contribute to sustainable mangrove management. However, over the past half-century, more than 70 percent of mangrove forests in China have vanished because of human activity. Because they are located in coastal zones, where population densities are typically high, mangrove areas are frequently converted to other uses, including fish and shrimp-farming, agriculture, salt production and urban development. In China alone, the last 50 years have seen a 70 percent loss of mangrove forests. It is characterized by low tree diversity, almost exclusively mangroves, with a low broken canopy. Best estimates are that about 10% of the world's coral reefs have been lost and perhaps up to 30% will be degraded in 10–20 years (Wilkinson 1992). The term \"rainforest\" has a wide classification.

One of the largest mangrove forests in the world is the Sundarbans, which straddles the border of India and Bangladesh. Mangroves are evergreen trees and shrubs that are well adapted to their salty and swampy habitat by having breathing roots (pneumatophores) that emerge from the oxygen-deficient mud to absorb oxygen. Their location combined with their low perceived value makes mangrove forests prime targets for for development.
