Troublingly, mangroves in the Philippines and around the world are already in retreat. These mangroves help mitigate the impact of storm surge and stabilize soil but have disappeared by almost half since 1918 due to deforestation (an issue for another day). For a long time there has been huge uncertainty in rates of mangrove deforestation (Friess & Webb 2011; 2014), but remote sensing tools have allowed us to quantify mangrove … In 2013, global Landsat imaging done from 1990-2010 by Jordan B. “The rest of Southeast Asia has seen a reduction in mangrove loss in recent decades, but mangroves are still threatened in many countries across the region,” he told Eco-Business. Besides this mangroves also provide construction timber for houses and fish traps and firewood. Originally, the Philippines had about 500,000 hectares of mangrove forest, but the country has lost more than half of that, despite their importance. Mangrove forests are highly diverse coastal ecosystems that that play a crucial role as a nursery for marine life, thus ensuring bountiful fishing in the future. In the Philippines, the rate of destruction, extrapolated from international data sources, is between 40 percent and 45 percent in the last 10 years. This figure is calculated by applying a fixed annual deforestation rate to the results of a previous inventory. 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. The mangrove has been at risk since demand for food has increased. The biggest mangrove deforestation “hotspots” were in Myanmar, Sumatra, Indonesian Borneo, and Malaysia. p. 97-107. Most deforestation of mangrove is caused by the mangrove conversion to fish ponds. Mangroven zijn boom- of struiksoorten die vaak een opvallend boven de grond of het water uitstekend wortelstelsel bezitten en die voorkomen in tropische kustgebieden en rivierdelta’s met getijdewerking.Met de term ‘mangrove’ wordt ook het (bos)gebied aangeduid waarin deze soorten voorkomen. 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. This study quantifies the proximate drivers (i.e., replacement land uses) of mangrove deforestation across Southeast Asia between 2000 and 2012. Aquaculture was a major pressure on mangrove systems during this period, but its dominance was lower than expected, contrary to popular development narratives. “Myanmar is currently a global hotspot of mangrove deforestation, primarily due to conversion to rice agriculture,” said Daniel Friess, associate professor at NUS’s department of geography. Productivity of the Mangrove Ecosystem: Management Implications. 4 It is important to realize that, in the Philippines, deforestation in secondary forests usually follows the felling of primary forests. MANGROVE DEFORESTATION `Mangroves are among the best natural defense of sheltered coastlines against wind and water during storms. Introduction. Deforestation can involve conversion of forest land to farms, ranches, or urban use. Local restoration and management of mangrove forests, in particular, are now widely advocated as a solution to achieve both economic and environmental conservation goals. Mangroves provide several ecological and socio-economic services to coastal communities valued at US$ 292,000/ha (UNEP 2007). Mangrove forests are among the most threatened habitats in the world, and mangrove loss is rampant across the globe. Changes in mangrove and brackish water pond area ( a ) and contribution of municipal fisheries and aquaculture ( b ) to total fisheries production in the Philippines, 1976–1990. What are mangroves? Philippine Forests Forests are among the most valuable natural resources in the Philippines. The Philippines is known to be one of the mangrove biodiversity centers in the world (next to Indonesia). However, there have been massive mangrove losses particularly during the 1970s-1990s periods. There is no reference to sustainability or the value of mangroves for local communities. In: Ong Jin-Eong and Gong Wooi-Khoon, 1984. Firstly, the difference between the spatial resolution of the deforestation data (CGMFC-21), which was 30 m, and lower resolution of other data products limited the detection of deforestation drivers in small mangrove forest areas, especially in the Philippines archipelago and eastern Indonesia. The deterioration of forest resources and poor economic performance in the Philippines call for a serious rethinking of economic policies addressing both environmental and economic objectives. 1970. Aquaculture and Mangroves in the Philippines. Despite this value, mangroves have faced deforestation pressures that have reduced their national coverage to less than 50% of what it was just 50 years ago. Rice, oil palm, and rubber expansion accounted for most conversion; however, our analysis revealed targeted systematic transitions of mangroves to water (presumably aquaculture) and built-up areas indicated emerging threats for mangroves from those … They provide a range of ecosystem services, ranging from the provision of food crops, livestock and fish to providing recreational experiences. You simply “go to the mangrove, cut it down and dig a fish pond. In 2013, a speaker at the 4th ASEAN Heritage Parks Conference noted that only around 100,000 hectares of mangroves remained. Thailand, Vietnam, and the Philippines showed comparatively lower rates of loss. 19% of the world’s mangroves were lost between 1980-2005, and the Philippines alone has already lost some 80% of its original mangrove cover - in part because policymakers have not … 288 000 Mangroves are a highly threatened ecosystem, as they are converted into other uses such as aquaculture and agriculture. "It is encouraging that our study found low rates of mangrove deforestation in Vietnam, the Philippines, and Brunei, and this is partly due to stronger protection of mangroves in these countries. 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. Recent environmental “narratives” suggest that local people are effective stewards of forest resources. In the Philippines, more than 50% of the country’s former 500,000 hectares of mangroves have been converted to fishponds over the last century. Deforestation is defined by cutting of tress in a forested area. Philippines Forest Information and Data According to the U.N. FAO, 25.7% or about 7,665,000 ha of Philippines is forested, according to FAO. Mangroves in the Philippines. Philippine mangrove ecosystems remain largely deforested, with a reforestation rate remaining at an alarmingly low level. Mangrove forests in the region were lost at an average rate of 0.18% per year. Mangrove forests are vital components to coastal environments in both tropical and sub-tropical regions. The most concentrated deforestation occurs in tropical rainforests. Another threat to mangroves is the over harvesting of marine life populations that put species in danger of becoming extinct or at least non-existent in that area. In the Philippines there is a manual for anyone interested in starting up their own fishpond. On the Philippine island of Samal in Davao Gulf, fishermen and students are planting thousands of mangrove seedlings financed by our donations. Gross mangrove deforestation was more profound: 63% of the 1996 mangrove extent had been temporarily or permanently converted by 2016. Of this 11.2% ( 861,000 ) is classified as primary forest, the most biodiverse and carbon-dense form of forest. Long of EROS and Chandra Giri of ARSC, both of which were contractors of USGS in South Dakota, published in the Journal of Coastal Research , the estimated total area of Philippine mangrove coverage at 256, 185 hectares in 2000, which was a bit higher than DENR ’s estimate of 247,362 hectares in 2003. In the Philippines, you may have noticed some of their projects such as Earth Hour and ROAD to 2020. In addition to their coral reefs, one of the best buffers against typhoons are the Philippine mangrove ecosystems. As a result of global mangrove deforestation, many millions of tonnes of carbon are released annually and coastal greenbelt defenses have disappeared or their effectiveness has been severely degraded. remote sensing Article Identifying Mangrove Deforestation Hotspots in South Asia, Southeast Asia and Asia-Pacific Samir Gandhi 1,* and Trevor Gareth Jones 1,2,3 1 Blue Ventures Conservation, Level 2 Annex, Omnibus Business Centre, 39-41 North Road, London N7 9DP, UK; trevor@blueventures.org You then put the fish in and feed them". That mangrove conservation and shrimp farming can co-exist in harmony in an environment of economic incentives supported by appropriate legislation, calls for a re-evaluation of the perception that shrimp farming necessitates deforestation and degradation of mangrove habitat (Ha et al., 2012). Mangroves: 11 facts you need to know These unique trees lead tough lives — but we’re all the better for it. About 31% of Earth's land surface is covered by forests. Mangroves are tropical trees that thrive in conditions most timber could never tolerate — salty, coastal waters, and the interminable ebb and flow of the tide. In 2013, the forestry sector contributed PhP5.26 billion (0.12%) to the national gross domestic Mangrove forest is one of the vital ecosystems in tropical countries. Mangrove Restoration in the Philippines. I chose Mangrove Restoration in the Philippines after learning about the devastating destruction over the years and the importance of this ecosystem to local communities. If you’re interest in helping out or at least learn more about them, we’ve provided a short list of the prominent environmental organizations found in the country.
