Senegal is home to around 185,000 hectares of mangrove estuaries in the Casamance and Sine Saloum regions, according to Livelihoods Funds. The figure is as high as 50% in countries such as India, the Philippines, and Vietnam, while in the Americas they are being cleared at a rate faster than tropical rainforests. But the recent mangrove deforestation to make way for development and shrimp farms has created hazardous conditions for people living close to shore. et al (2016). Such deforestation rate represents a potential loss of 2.0–7.5 million tonnes C yr −1 from mangrove soils, which corresponds to ~7.3–27.5 million tonnes of CO 2 … The report also claims this industry to be driven by certain essential factors, a â ¦ With 18% of the regionâ s mangrove cover, deforestation rate in this country (1.1 and 0.6%) exceeded the South American average (0.69 and 0.18%) in estimates for 1980â 1990 and 2000â 2005. FAO experts expect that a global halt on deforestation will take another 25 years to achieve. Threats to mangrove forests and their habitats include: An international team of 22 researchers led by National University of Singapore (NUS) has found that the global loss rate of mangrove forests is less alarming than what has been previously suggested, a welcome development for one of the most valuable ecosystems on the planet. some other tropical ecosystems; for example, between 1990 and. In 1980, the total mangrove area worldwide was approximately 198,000 km 2 . The study also indicates that mangrove deforestation continues, albeit at a slightly lower rate in the 1990s (1.1 percent per annum) than in the 1980s (1.9 percent per annum), reflecting the fact that most countries have now banned the conversion of mangroves for aquaculture purposes and require environmental impact assessments prior to large-scale conversion of mangroves for other uses. 2016. Forest loss occurs at a constant rate. We provide a standardized spatial dataset that monitors mangrove deforestation globally at high spatio-temporal resolutions. Quantification of deforestation rates and land cover and land use transitions has been impeded by the lack of robust mangrove cover maps. Mangrove deforestation in Indonesia results in a loss of 190 million metric tonnes of CO 2 annually. (2)Department of Geography, National University of … Carbon dioxide may take some time to be released once a mangrove forest is cleared. NUS scientists found that more than 60% of the mangrove cover in Myanmar had been converted to agricultural and other purposes over a period of 20 years (1996 – 2016). Due to deforestation, Myanmar also suffered a net loss of 2,397 million US$/year in its mangrove ecosystem service value (i.e. During the aforementioned period, Johor has lost about 6120.70 ha (20.54%) of mangroves with annual loss rate of 1%, which is almost same with the global deforestation rate [2]. The researchers discovered that the mangrove deforestation rates in Southeast Asia were lower than previously thought. Unfortunately, Trinidad and Tobago are guilty of mangrove deforestation. This loss was mainly attributed to clearing mangroves for aquaculture and rice cultivation. On August 20, 2020, Climatelinks and the USAID-funded Climate Economic Analysis for Development, Investment, and Resilience (CEADIR) Activity co-sponsored a webinar on CEADIR’s cost-benefit analysis of mangrove conservation in Indonesia.

Rates and drivers of mangrove deforestation in Southeast Asia, 2000-2012. Deforestation for fuel & timber accounts for the ongoing loss of approximately 26 percent of existing mangroves (Valiela et al. [ Links ] Smith SM, Snedaker SC. Deforestation can involve conversion of forest land to farms, ranches, or urban use. In 2000, the total area was less than 150,000 km 2 , a 25% decrease from 1980. 28.7% decrease from 2000), in which maintenance of fisheries nursery populations and habitat and coastal protection were among those services that were greatly affected. Since 1998, Bintuni Bay has had a mangrove harvesting concession for wood chips that operates at a sustainable extraction rate. However, deforestation rates have persisted throughout the past few decades despite the known consequences. The practice of mangrove restoration is grounded in the discipline of restoration ecology, which aims to “[assist] the recovery of resilience and adaptive capacity of ecosystems that have been degraded, damaged, or destroyed”. Richards DR, Friess DA. Droughts and deforestation have claimed a total surface area of approximately 45,000 hectares of mangroves. They also identified the rapid expansion of rice agriculture in Myanmar, and sustained conversion of mangroves to oil palm plantations in Malaysia and Indonesia, as increasing and under-recognised threats to the mangrove ecosystems. Richards DR(1), Friess DA(2). A new study by researchers from the National University of Singapore (NUS) indicated that mangrove deforestation rates in Myanmar greatly surpassed previous estimates, as more than 60 percent of the forest had been converted to other uses in the last 20 years. 2010, peatland forests experienced a net loss of 54,000 km 2 in. are near coral reefs. Light: High. 2001). Across all six states/regions and collectively, our estimates indicate (1) a greater mangrove extent historically, and (2) faster deforestation rates, than previous studies. Rates and drivers of mangrove deforestation in Southeast Asia, 2000-2012. The rapid deforestation of mangroves in Myanmar has also been detailed in another study, led by Daniel Richards and Daniel Friess, two researchers at the National University of Singapore who investigated the rate of mangrove deforestation in Southeast Asia, including Myanmar, between 2000 and 2012. Mangrove reforestation has had very low success, although new hydrology-based methods may be more promising (Lewis & Gilmore 2007). Evidence suggests that emissions are lost at a rate … Mangrove restoration is the regeneration of mangrove forest ecosystems in areas where they have previously existed. But since the 1970s, around 25% of the country’s mangrove forests have been lost. Climate and sea level have drastically altered mangrove distribution since their appearance in the geological record ∼75 million years ago (Mya), through to the Holocene. The most concentrated deforestation occurs in tropical rainforests. Mangrove deforestation rates are. Overall rate of loss has slowed for mangroves and all forests globally, but there is still work to be done. Along with Myanmar, that is also seeing high rates of mangrove destruction, it makes Southeast Asia a region of extreme mangrove carbon loss. While mangrove loss rates may not be as high as the rate of tropical deforestation, the conservation battle continues. Deforestation, clearance, clearcutting or clearing is the removal of a forest or stand of trees from land which is then converted to a non-forest use. Their removal poses a threat. In Johor, the deforestation mainly concentrated to the southwestern part due to both small scale and large scale development projects in agriculture, aquaculture, infrastructure, industries or urban development [3]. to two major, highly productive tropical eco- Deforestation, a land use and land cover (LULC) defined here as the complete removal of a mangrove forest or stand of mangrove trees where the land is thereafter converted to a non-forest use, has occurred globally at a rate of 1 to 2% per year. Explore interactive global tree cover loss charts by country. Substantial mangrove deforestation in Myanmar Edward WEBB (Group Leader, Biological Sciences) March 03, 2020. Indonesia is home to 30 % of the world’s mangroves and is also seeing the most rapid deforestation, nearly 50% of the world’s total mangrove loss. Intertidal mangrove forests are a dynamic ecosystem experiencing rapid changes in extent and habitat quality over geological history, today and into the future. Proceedings of the National Academy of Sciences 113: 344-349. Richards, D.R. global mangrove deforestation pattern from 2000 to 2012 is one of decreasing rates of deforestation, with many nations essentially stable, with the exception of the largest mangrove-holding region of Southeast Asia. Analyze global forest data and trends, including land use change, deforestation rates and forest fires. 1995. In Southeast Asia between the years 2000-2012 the rate of mangrove loss due to deforestation was an average 0.18% per year. GFW data indicate that the world lost between 9,000 and 25,000 hectares (22,000-62,000 acres) of mangroves each year between 2001 and 2012, and that’s not considering the enormous damage done prior to 2001. Even so, we cannot rely on reforestation to prevent mangrove loss. mangrove deforestation rate is relatively low in comparison with. About 31% of Earth's land surface is covered by forests. Salinity responses in two populations of viviparous Rhizophora mangle L. seedlings. Biotropica 27: 435-440. “The rate of mangrove forest expansion is considerable in South Asia (6), so it is possible that the percentage net loss in mangrove forest area in Southeast Asia between 2000 and 2012 may be less than 2%.” (347) Mangrove conversion to aquaculture is the main factor in mangrove loss. However the report did show that there has been a slowdown in the rate of mangrove loss: from some 187,000 ha destroyed annually in the 1980s to 102,000 ha a year between 2000 and 2005. We estimated a total of 13 233 km 2 of mangroves across Myanmar in 1996, with more than 90% occurring in the regions/states of Ayeyarwady, Rakhine, and Tanintharyi (figure 1 ; table 1 ). More than 35% of the world’s mangroves are already gone. high in the Americas, and many of these forests. [ Links ] In the 1950s, coastal villages in the Indo-Pacific had an average of 5 miles of mangrove forest between themselves and the ocean.
