Mangroves and climate change Updated: Thu, 18 Oct 2018. “We see mangroves as an important habitat for marine life that use the mangroves as their homes. Between 2000 and 2015 mangrove destruction released up to 122 million tons of carbon — more than two and a half times the amount emitted by California wildfires between 2001 and 2010. The country’s annual monsoon season has also worsened, including catastrophic floods this summer. Published by omlwordpress at … According to a recent NASA-led satellite study, mangrove forests move significantly more CO2 from the atmosphere into long term storage, than other forest ecosystems, making them “among the planet’s best carbon scrubbers.” 7 8 The role of coastal marine ecosystems in this natural form of carbon capture and storage is another example of how oceans influence climate on a regular basis. That’s the good news. Except for tundra and peatlands, mangroves store more Corg per unit area than any other ecosystem. Mangroves play a critical role in protecting lives and property in low-lying coastal areas from storm surges, which are expected to increase with climate change. Yet these ecosystems are exceptionally prone to extinction due to increased human interventions and changes in environmental boundary conditions. However, despite wide distribution, over two-thirds of the world’s mangroves are found in just 12 countries, with Indonesia alone accounting for over 20% of the total mangrove cover of the world. Mangrove forests serve a critical role in climate regulation and climate change mitigation. The sediments beneath these habitats are characterized by typically low oxygen conditions, slowing down the decay process and rates, resulting in much greater amounts of carbon accumulating in the soil. Wait too long and we’ll lose more than prime snorkeling spots. As compared to terrestrial ecosystems, the research focus on coastal and marine systems is about a decade behind. “It astounds me that no one does a cost-benefit analysis to show that removing them increases rather than decreases pollution and damages.”. var gcse = document.createElement('script'); Fish of all kinds and sizes hung out among the tree roots, including huge cubera snappers. “This is another one. Further, studies have shown that per hectare, mangrove forests store up to five times more carbon than most other tropical forests around the world. Background. The conservation of mangroves and associated ecosystems is a key natural adaptation strategy and mitigation measure to climate change. The most substantial loss of the world’s mangrove cover is due to their conversion to other land uses, such as urban area expansion, industrial development, aquaculture, agricultural development, and charcoal making. Mangroves are one of the most productive ecosystems on the earth. Yet, these people are often unaware of the key role mangroves may play, especially if the associated fisheries are offshore. Perspective Global Significance of Mangrove Blue Carbon in Climate Change Mitigation Daniel M. Alongi Tropical Coastal & Mangrove Consultants, 52 Shearwater Drive, Pakenham, VIC 3810, Australia; Waves lose their power passing through dense mangrove … Climate Change How Singapore's mangroves can contribute in the battle against climate change. impacts of climate change, it has never been more important to conserve and in some cases, restore, the natural protection that is offered by mangrove ecosystems in the BVI. There are a number of other non-timber benefits extracted from the range of mangrove forest species, including honey, tannin from bark, thatch material, edible fruits, fodder. So when you have a mangrove along the coast and you have a strong current, the current hits the roots and the energy of the wave dissolves." The important ones include the Ayeyarwady delta in Myanmar (Burma), the Mekong in Vietnam, and the extensive deltaic coastline along southern Papua in Indonesia. observed. Pierre Taillardat. Mangroves for the Future (MFF) program, IUCN, FAO's work on mangrove conservation and management. A 2018 study calculated that the world’s mangrove forests suck up more than 6 billion tons of carbon a year. Climate change refers to a change in the state of the climate that can be identified by changes in the mean and/or the variability of its properties and that persists for an extended period, typically decades or longer (IPCC 2014).Managing the risks of climate change involves mitigation and adaptation decisions with implications for future generations, economies, and environments. This can be attributed to the region’s highly conducive environment for the growth of mangrove forests, characterized by such qualities as a humid climate, high rainfall, and a number of rivers with large deltas supplying freshwater and sediments. But the world isn’t leaving mangroves alone: We continue to actively destroy their forests at an increasing rate, clearing them for development and aquaculture, timber and fuel. Recent experiences of tsunami and major storms in Southeast Asia and other parts of the world have shown that mangroves can and have played important roles in absorbing and weakening wave energy as well as preventing damage caused by debris movement. The capacity of mangroves, sea grasses, and salt marshes to sequester carbon dioxide from the atmosphere is becoming increasingly recognized at an international level. gcse.async = true; The entangled root systems of mangroves, which anchor the plants into underwater sediment, slow down incoming tidal waters, allowing organic and inorganic material to settle into the sediment surface. That country recently approved a $9.3 billion tourist development to be built largely on filled-in coastal land within the reserve’s buffer zone. Describing what is already happening and what may happen in the future . The trees/shrubs themselves, as well as the soil beneath them, serve as … The bad news: Mangroves face numerous threats — 35% were lost between 1980 and 2000, and since the turn of the 21st century almost 1 in 50 of the remaining mangrove forests has been cut down. There are isolated examples of a few very useful research studies, but a comprehensive account of the various ecological, economic, and bio-physical roles played by mangrove forests is still lacking. One feature of mangroves that we’ve long benefited from is the protection they offer to our coastlines. Mangrove forests could play a crucial role in protecting coastal areas from sea level rise caused by climate change, according to new research involving the University of Southampton. 1. The aerial roots of mangroves hold back sediments and reduce pollutants from sewage and aquaculture in estuaries and coastal waters. The aim of this review was to present the impacts of a range of climate change factors on mangroves at a regional scale, and then to synthesize these trends at a global scale. This is disconcerting to scientists because the hardy brackish tidal tree in an important bulkhead against climate change, according to findings is … Moreover, intact and healthy mangroves act as a natural buffer, contributing to the reduction of impact forces and depth and velocity of natural hazards, thus contributing to coastal communities’ ability to adapt as the frequency and severity of such events increases as a result of climate change. They provide important habitat for a wide variety of terrestrial, estuarine and marine species — from fish to birds and manatees — and supply nutrients and sediments for seagrass-bed and coral-reef habitats. After completion of the bridge, the port likely will be used more frequently, with more factories and that sort of thing.”. A community based learning center established in Pred Nai village links natural resource and environmental conservation initiatives at the local level and establishes communication between concerned units at the provincial level and community members who play a vital role in natural resource conservation in Trat. Mangrove forests can absorb storm surges, cut flooding, absorb and store climate-changing carbon dioxide and provide rich fishing grounds. "Mangrove ecosystems are threatened by climate change. Despite high rates of destruction and degradation, mangroves still play key roles in ameliorating coastal erosion, fostering coastal stability and assisting in human sustainability. In many countries, mangrove wood is used to produce charcoal, and as firewood. RECOFTC has been following a similar approach in eastern Thailand in Pred Nai village, Trat Province, with very encouraging results for the past two decades. Mangrove forests have survived a number of catastrophic climate events since first appearing along the shores of the Tethys Sea during the late Cretaceous-Early Tertiary. Super Typhoon Yolanda Rapid Assessment Report No.2 November 28, 2016. International Climate Protection Fellowships November 28, 2016. “The government is definitely focusing only on development and not the environment,” he says. Mangrove forests are incredibly productive ecosystems. Thus, at the global scale, coastal wetland destruction could account for 1-3% of industrial emissions; a number that is on the rise as more and more coastal wetlands are destroyed every year around the world. The existence of mangrove peat deposits worldwide attests to past episodes of local and regional extinction, primarily in response to abrupt, rapid rises in sea level. Recent experiences of tsunami and major storms in Southeast Asia and other parts of the world have shown that mangroves can and have played important roles in absorbing and weakening wave energy as well as preventing damage caused by debris movement. The report recommends several measures to conserve and restore mangroves. One of the ecologic services providing by mangroves is to buffer the impacts of waves, storm surges, and tsunamis on coastal property and infrastructure by dissipating incoming wave energy (Barbier et al., 2008; Cochard et al., 2008).The role of mangroves in attenuating short-period wave energy has been well documented by theoretical analysis and field observations … According to U.S.- based Conservation International, mangroves can store up to 10 times more carbon than land-based forests.
