Role of Mangrove Forests in Climate Change Adaptation. Mangroves have declined by nearly half in the last 50 years. Some specific trends and mangrove responses . Climate change also affects their survival. Introduction. Sharif A. Mukul, a research fellow at the University of the Sunshine Coast in Queensland, Australia, warned in a recent letter to Science that construction of a 3.8-mile-long bridge, the largest development project in Bangladesh, could destroy the Sundarbans. A paper published in Science in June looked at data on thousands of years of sea-level rise and mangrove accretion. Carbon offsets based on the protection and restoration of coastal vegetation could therefore be far more cost effective than current approaches focused on terrestrial and peat forests, even before taking into consideration the enormous additional benefits to fisheries, coastal protection, and the livelihoods of coastal inhabitants. Yet, these people are often unaware of the key role mangroves may play, especially if the associated fisheries are offshore. Mangrove forests play an important role in providing breeding grounds and habitats to a variety of fishes and other marine species of high commercial value, including mud crabs, mollusks, and prawns. Of all the biological carbon, also termed as ’green carbon’, captured in the world, over half (55%) is captured by mangroves, sea grasses, salt marshes, and other marine living organisms, which are also known more specifically as ’blue carbon’. Show all. The important ones include the Ayeyarwady delta in Myanmar (Burma), the Mekong in Vietnam, and the extensive deltaic coastline along southern Papua in Indonesia. In terms of climate change mitigation, mangroves serve as carbon sinks and the loss of mangrove forests can result in significant release of stored carbon. And mangrove forests also help mitigate climate change, pulling massive amounts of greenhouse gases from the atmosphere and storing them in their soils — up to four times as much carbon as other tropical forests. Mangroves in the Everglades. observed. In order to raise awareness of the multiple benefits of mangrove ecosystems, there is a need to conduct more research and also focus more on expanding mangrove areas in participation with local communities and other key stakeholders. Mangrove forests can absorb storm surges, cut flooding, absorb and store climate-changing carbon dioxide and provide rich fishing grounds. And mangrove forests also help mitigate climate change, pulling massive amounts of greenhouse gases from the atmosphere and storing them in their soils — up to four times as much carbon as other tropical forests. 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. 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. Several studies have shown that mangroves play crucial roles in protecting coastal communities from the impact of large storms. "Mangrove ecosystems are threatened by climate change. 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. Colombia, which has approximately 1,467 square miles of mangrove forests on its coasts, is experiencing the highest annual rate of loss in South America — roughly 154 square miles in the past three decades. Some 210 million people live in low elevation areas within 10 km of mangroves and many of these directly benefit from mangrove-associated fisheries. Mangrove blue carbon strategies for climate change mitigation are most effective at the national scale. But far less attention has been paid to a similar and equally important type of biome that is also increasingly at risk: Mangrove forests. The capacity of mangroves, sea grasses, and salt marshes to sequester carbon dioxide from the atmosphere is becoming increasingly recognized at an international level. specific impacts to mangroves as a results of climate change, even if this is the case (Nurse et al., 2014; National Academies, 2016). 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. Climate Change How Singapore's mangroves can contribute in the battle against climate change. Climate Change How Singapore's mangroves can contribute in the battle against climate change. Further, studies have shown that per hectare, mangrove forests store up to five times more carbon than most other tropical forests around the world. Recent studies are showing mangroves role in climate mitigation goes even further. 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. 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. Our new website can be found here at https://www.recoftc.org. 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. They are a critical natural solution to the most daunting challenge we face – how to cope with climate change as well as limit global warming to well below 2ºC. 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. An estimated 75 percent of game fish, and 90 percent of commercial species in South Florida depend on … Such knowledge gaps have implications for estimates of ecosystem service provision and change, as seen in mangroves ... 2017 Clarifying the role of coastal and marine systems in climate mitigation. A 2018 study calculated that the world’s mangrove forests suck up more than 6 billion tons of carbon a year. Mangroves, although considered a ‘soft’ option when compared to seawalls, can be one of the most effective forms of coastal protection that in addition provide a range of other benefits. After completion of the bridge, the port likely will be used more frequently, with more factories and that sort of thing.”. The rate of sea level rise has doubled from 1.8 millimeters per year over the 20th century to ∼3.4 millimeters per year in recent years. Weather in Mangrove Forests can ranges drastically because of their location in mainly tropical climates around the world. 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 bridge will bring economic benefits to the region and Mukul does not argue against its construction, but rather for doing it in a way that protects local ecosystems and their services. Now, in a harbinger of climate change, mangroves are expanding from tropical zones into temperate areas. “People on the coast don’t want mangroves blocking their view,” she says. ... As a coastal forest ecosystem, the role of mangroves in achieving SDGs 14 and 15 is. gcse.async = true; Coastal mangrove forests help protect communities and habitats from storm surges, but sea-level rise could wipe them out. “The government is definitely focusing only on development and not the environment,” he says. It’s not too late, but it is urgent.”. Saintilan et al. Source: ANTARA NewsDate: 13 May 2020 Forestry climate expert Daniel Murdiyarso said the existence of mangroves could have an important role in efforts to reduce greenhouse gas (GHG) emissions to curb climate change. Adapting to climate change. Primary blame goes to human activities, including logging and development, primarily for tourism. But if mangroves … The important ones include the Ayeyarwady delta in Myanmar (Burma), the Mekong in Vietnam, and the extensive deltaic coastline along southern Papua in Indonesia. The aerial roots of mangroves hold back sediments and reduce pollutants from sewage and aquaculture in estuaries and coastal waters.Coastal protection is another important function of mangrove forests, serving as a natural barrier against storms, typhoons, and tsunami, and thus protecting coastal inhabitants. Fish of all kinds and sizes hung out among the tree roots, including huge cubera snappers. Carbon offsets based on the protection and restoration of coastal vegetation could therefore be far more cost effective than current approaches focused on terrestrial and peat forests, even before taking into consideration the enormous additional benefits to fisheries, coastal protection, and the livelihoods of coastal inhabitants.Therefore, cutting down mangroves means releasing larger amounts of carbon into the atmosphere. The effects of climate change are already being felt, especially in many coastal areas. NPS image by Matt Johnson. 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 … 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. of the world’s mangroves – more than any other region in the world. Mangroves in … However, despite such diversity in the roles of mangroves, these ecosystems are still often seen as valueless wastelands available for other uses. Annually, during the hurricane season, coastal 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. The country’s annual monsoon season has also worsened, including catastrophic floods this summer. In fact, mangroves have more carbon in their soil alone than most tropical forests have in all their biomass and soil combined. (Accretion is the opposite of coastal erosion: Instead of wearing away, soil builds up around the roots and lifts trees vertically, keeping them above water.) An initiative of the Center for Biological Diversity. and medicinal properties of certain species with potential commercial applications and recreational values. Pierre Taillardat. Indonesia, Malaysia and Myanmar accounted for more than two-thirds of the released amount. 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 should do the project in a more environmentally friendly way.”. ... about one per cent - they have a role to play when it comes to carbon storage. Blue carbon is the carbon stored in coastal and marine ecosystems. On a regional scale, Southeast Asia has one-third (51,049 km. ) Background. Earthscan Publishers, London. The entangled roots of mangrove forests help to stabilize coastal areas through sediment capture and bio-filtration of nutrients and some pollutants from the water, and reducing coastal erosion. . Mangroves and marshes key in the climate change battle 02/02/2017 03:47 am ET Updated Feb 02, 2018 With the advent of green technologies, it is easy to view the battle against climate change … Mangroves and Climate Change. Mangrove forest canopy near Jones Lagoon. A lesser-known but increasingly recognised solution lies in nature. The hidden beauty of a mangrove forest. In other words, just leaving mangroves alone could help. CARIBBEAN MARINE CLIMATE CHANGE REPORT CARD: SCIENCE REVIEW 2017 Science Review 2017: pp 60-82. 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. (function() { Climate change is not just characterised by rising global temperatures, but also rising frequencies and strength of extreme weather events such as cyclones, typhoons and hurricanes. Mangrove forests are incredibly productive ecosystems. We’d love for you to join us elsewhere on the web: Copyright 2011 www.recoftc.org All Rights Reserved. These efforts are also aimed at promoting policy support for local authority decentralization, and providing technical and technological support to local officers on natural resources management planning, and strategies on strengthening community self-management. This ability of mangroves and other coastal vegetation to store such large amounts of carbon is, in part, due to the deep, organic rich soils in which they thrive. Mangroves and climate change Mangrove forests can absorb storm surges, cut flooding, absorb and store climate-changing carbon dioxide and provide rich fishing grounds. 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. Climate change will also increase the number of intense hurricanes, a change that will influence mangrove seed dispersal. 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. s.parentNode.insertBefore(gcse, s); This is an important initiative to better understand the roles of mangroves in local livelihoods and also for climate change mitigation and adaptation at the local level. gcse.type = 'text/javascript'; Mangrove forests store and sequester large area-specific quantities of blue carbon (Corg). 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. The authors determined that accretion will not keep up beyond sea-level rise of 0.27 inches per year. According to the 2010 World Atlas of Mangroves. And when the water gets too high, and the accretion process fails to support mangroves, the trees effectively drown. Mangrove plants are mostly trees and large shrubs, but also include ferns and a palm species. Mangrove ecosystems serve as breeding, feeding, and nursery grounds for many shellfish, fish, and other wildlife. Mangroves are prevalent in tropical south Florida, but the plants have been moving farther north as climate change makes freezing weather less common. Mangrove forests can help fight the effects of climate change Posted on Jan 16, 2019 But they're in danger. With the advent of green technologies, it is easy to view the battle against climate change as one for the tech world. 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. Since the 1970s, aquaculture development has decimated vast areas of mangrove forests in the Gulf of Thailand, Vietnam, Java and Kalimantan in Indonesia, and the Philippines. 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. They perform a variety of useful ecological, bio-physical, and socio-economic functions, and are the source of a multitude of benefits to coastal populations. “We need to modify infrastructure, change permitting rules, and come up with other innovative solutions to accommodate that movement,” Geselbracht says. Yet, these people are often unaware of the key role mangroves may play, especially if the associated fisheries are offshore. ; Coastal ecosystems such as mangroves, tidal marshes and seagrass meadows sequester and store more carbon per unit area than terrestrial forests and are now being recognised for their role in mitigating climate change. Rutgers University climate data scientist Erica Ashe, one of the authors, says the current global rate is 0.134 inches, with some areas experiencing much higher rates. 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. The trees cannot grow on roads or buildings. Every year thousands of tons of shrimps from aquaculture farms from Southeast Asia are exported to western markets. Mangrove blue carbon strategies for climate change mitigation are most effective at the national scale. Climate change is not just characterised by rising global temperatures, but also rising frequencies and strength of extreme weather events such as cyclones, typhoons and hurricanes. Describing what is already happening and what may happen in the future . We have an opportunity, if we take this and all the other effects of rising temperatures seriously. 1. Except for tundra and peatlands, mangroves store more Corg per unit area than any other ecosystem. investigated the likely effects of this increasing rate of rise on coastal mangrove forest, a tropical ecosystem of key importance for coastal protection (see the Perspective by Lovelock). In addition, Bangladesh already has seen significant loss of mangrove forests to shrimp farming. That’s the good news. Mangrove forests grow in the tidal lagoons of tropical coastlines and they could actually benefit from climate change. '//www.google.com/cse/cse.js?cx=' + cx; Through science, policy and partnerships, Conservation International works to protect mangroves around the world. Pierre Taillardat. Introduction. A single acre of mangroves can drop two to three tons of leaves per year! Mangrove forests like this may be one of the world’s most underappreciated landscapes. that is emitted annually due to the destruction of mangrove forests globally. This project also includes a massive bridge. An hour stretched into two, this enormous saltwater aquarium proving as fascinating as the nearby, healthy coral reefs. One of the key challenges facing mangrove conservation is inadequate understanding of their multiple roles due to poor research, particularly in the areas of climate change mitigation and adaptation. Mangroves and climate change Updated: Thu, 18 Oct 2018. Super Typhoon Yolanda Rapid Assessment Report No.2 November 28, 2016. International Climate Protection Fellowships November 28, 2016. The report indicates that the effects of climate change could result in a loss of a further 10 - 15 per cent of mangroves by year 2100. The entangled roots of mangrove forests help to stabilize coastal areas through sediment capture and bio-filtration of nutrients and some pollutants from the water, and reducing coastal erosion.
