Along with Myanmar, that is also seeing high rates of mangrove destruction, it makes Southeast Asia a region of extreme mangrove carbon loss. Mangrove deforestation rates are. Deforestation can involve conversion of forest land to farms, ranches, or urban use. Mangrove restoration is the regeneration of mangrove forest ecosystems in areas where they have previously existed. However, deforestation rates have persisted throughout the past few decades despite the known consequences. Richards DR, Friess DA. 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. Evidence suggests that emissions are lost at a rate … Overall rate of loss has slowed for mangroves and all forests globally, but there is still work to be done. 1995. Droughts and deforestation have claimed a total surface area of approximately 45,000 hectares of mangroves. Even so, we cannot rely on reforestation to prevent mangrove loss. Since 1998, Bintuni Bay has had a mangrove harvesting concession for wood chips that operates at a sustainable extraction rate. Quantification of deforestation rates and land cover and land use transitions has been impeded by the lack of robust mangrove cover maps. high in the Americas, and many of these forests. Rates and drivers of mangrove deforestation in Southeast Asia, 2000-2012. 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. Senegal is home to around 185,000 hectares of mangrove estuaries in the Casamance and Sine Saloum regions, according to Livelihoods Funds. In 2000, the total area was less than 150,000 km 2 , a 25% decrease from 1980. More than 35% of the world’s mangroves are already gone. 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. Mangrove deforestation in Indonesia results in a loss of 190 million metric tonnes of CO 2 annually. 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. 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 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”. FAO experts expect that a global halt on deforestation will take another 25 years to achieve. Light: High. We provide a standardized spatial dataset that monitors mangrove deforestation globally at high spatio-temporal resolutions. Their removal poses a threat. Across all six states/regions and collectively, our estimates indicate (1) a greater mangrove extent historically, and (2) faster deforestation rates, than previous studies. In 1980, the total mangrove area worldwide was approximately 198,000 km 2 . 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. Substantial mangrove deforestation in Myanmar Edward WEBB (Group Leader, Biological Sciences) March 03, 2020. 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. 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. Salinity responses in two populations of viviparous Rhizophora mangle L. seedlings. some other tropical ecosystems; for example, between 1990 and. The 'Emission rate' slider controls this rate of emissions once an area of forest is lost. The most concentrated deforestation occurs in tropical rainforests. to two major, highly productive tropical eco- Analyze global forest data and trends, including land use change, deforestation rates and forest fires. Threats to mangrove forests and their habitats include: 2016. mangrove deforestation rate is relatively low in comparison with. Explore interactive global tree cover loss charts by country. Richards DR(1), Friess DA(2). (2)Department of Geography, National University of … In Southeast Asia between the years 2000-2012 the rate of mangrove loss due to deforestation was an average 0.18% per year. 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). 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. 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. While mangrove loss rates may not be as high as the rate of tropical deforestation, the conservation battle continues. But since the 1970s, around 25% of the country’s mangrove forests have been lost. Author information: (1)Department of Geography, National University of Singapore, Singapore 117570 Department of Animal and Plant Sciences, The University of Sheffield, Sheffield S10 2AS, United Kingdom d.r.richards@nus.edu.sg. Unfortunately, Trinidad and Tobago are guilty of mangrove deforestation. Intertidal mangrove forests are a dynamic ecosystem experiencing rapid changes in extent and habitat quality over geological history, today and into the future. Carbon dioxide may take some time to be released once a mangrove forest is cleared. 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]. “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. 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. This loss was mainly attributed to clearing mangroves for aquaculture and rice cultivation. Mangrove reforestation has had very low success, although new hydrology-based methods may be more promising (Lewis & Gilmore 2007). 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 … 2001). 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 ). are near coral reefs. 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. 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. The researchers discovered that the mangrove deforestation rates in Southeast Asia were lower than previously thought. Due to deforestation, Myanmar also suffered a net loss of 2,397 million US$/year in its mangrove ecosystem service value (i.e. But the recent mangrove deforestation to make way for development and shrimp farms has created hazardous conditions for people living close to shore. 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. About 31% of Earth's land surface is covered by forests. Proceedings of the National Academy of Sciences 113: 344-349. Richards, D.R. 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. 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. Deforestation for fuel & timber accounts for the ongoing loss of approximately 26 percent of existing mangroves (Valiela et al. In the 1950s, coastal villages in the Indo-Pacific had an average of 5 miles of mangrove forest between themselves and the ocean. Forest loss occurs at a constant rate. [ Links ] Smith SM, Snedaker SC. Rates and drivers of mangrove deforestation in Southeast Asia, 2000-2012. 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.
