It’s time the Government came forward to preserve and restore the mangrove ecosystems. Threats to mangrove forests and their habitats include: Clearing: Mangrove forests have often been seen as unproductive and smelly, and so cleared to make room for agricultural land, human settlements and infrastructure (such as harbours), and industrial areas. While these issues are by no means exhaustive, they represent the most pressing issues. There are several threats to the mangrove ecosystem though they may vary from region to region. Beyond the risk of development, mangrove ecosystems suffer greatly from over-fishing and over-harvesting of their valuable resources, such as timber which can be used for firewood and construction in local communities. An integral part of our Eco Tour is showing people the mangrove plants within the North Sound and how they sustain life there within that diverse and delicate ecosystem. Pointing out to the rich diversity of mangroves in Odisha, he said, “The State is often referred to as a biological paradise for mangroves. Soon after, the impact of destruction was felt. Weak governance and loose environmental regulations exacerbate many of these issues. Mangrove communities including invertebrates, fishes, and plants are also highly susceptible to damage from petroleum products. Second line of defence is casuarinas and then comes mangroves, which spread up to a distance till which the tidal waves can reach and, thus, protect the ainland from sea erosion. Large brackish water bodies and complex network of tidal creeks and canals feature the mangrove wetlands of Odisha. Accessed on February 14, 2017. It is… Mangrove Forests: Threats Mangrove forests are one of the world’s most threatened tropical ecosystems. Some of the largest wetlands are the Sundarbans mangrove forest in the Ganga-Brahmaputra delta, the Amazon River basin, and the Pantanal. Another major threat to mangroves is anthropogenic climate change. Mangrove ecosystems are under threat from a changing set of pressures. It is estimated that the world may lose all its vital mangrove ecosystems in just a century’s time if the current rate of degradation continues, he warned. One of the greatest threats to mangrove forests is their deforestation and conversion for aquaculture, the fastest growing food production system in the world today3. Super Cyclone are well aware of the life saver species and are engaged in creation of new mangrove forests and regenerate the degraded forest. Though in the country, the Sunderbans has large area – about 2,700 sqkm – it has only 52 varieties of the species, whereas Odisha has only 219 sqkm of the unique forest, but the species diversity is 62, he told. At a time when countries around the world have recognised the value of mangroves as a tool to arrest global warming by sequestering carbon, the Government’s move for expansion of the Paradip Port and other developmental activities under the much-touted Central scheme Sagarmala has drawn flak not only from environmentalists and climatologists but from the coastal community, including fisher folk. There are several villages in the district which have planted the species and are nurturing them for years. We first describe the various climate change impacts expected to affect the mangrove ecosystem, particularly sea level rise, storminess, precipitation, and temperature. Destruction of mangrove forests is occurring globally. Threats to mangroves from climate change and adaptation options. Emphasising on the natural regeneration of the species, the botanist said it is important to identify sites where mangroves can grow naturally and initiate steps to promote the growth there. In a study from 2014, mangrove forests were found to provide ecosystem services (benefits to humans) valued at $194,000 per hectare annually.Today is International Mangrove Day and here are just a few reasons we should care about mangroves – and invest in protecting them:. Mangroves form the foundation of a highly productive and biologically rich ecosystem which provides a home and feeding ground for a wide range of species of planktons, snails, fishes, shrimps, seashells and even insects, many of which are endangered. This book focuses on the worldwide threats to mangrove forests and the management solutions currently being used to counteract those hazards. At present, about 1% of global mangrove coverage continues to be destroyed each year. Ellison, J. That means the chopped off mangroves can release the carbon dioxide (CO2) back to the atmosphere causing more climate change, Panda told. However, mangroves do have the ability to adapt to sea level rise if it occurs slowly enough so that they may retreat, assuming that they have space on the landward side to expand and that several other environmental conditions are met5. Designed for the professional or specialist in marine science, coastal zone management, biology, and related disciplines, this work will appeal to those not only working to protect mangrove forests, but also the surrounding coastal areas of all types. “The plantation site at Nuagaon now houses more than 35 bird species, including migratory birds. University of Tasmania, Australia. 1. Environmentalists say while the lifesaving cover across the shoreline has already under severe stress due to destruction in the name of development, the multi-billion-crore project would only add to the stress level and cause serious damage to the coastal ecosystems. Sea level rise and sedimentation off-balance the delicate adaptations of a mangrove tree to its environment, inhibiting its development or killing it off. Accessed on February 14, 2017. Available at: Gilman, E., Ellison, J., Duke, N., and C. Field (2008). It would damage the environment of coastal belts and affect the livelihood of lakhs of fishermen in the State. Most of the coastal community members who are survivors of the 1999. More than 35% of the world’s mangroves are already gone. Wetlands are found in every continent. They are : Don’t throw your plastic or waste away at beach or coastal area, it makes a threat to our ocean ecosystem. Rapid development of roads, ports, marinas, and coastal communities means that more mangrove forests are being destroyed. Each of the 40 households of the village gave away their unused private land for the creation of mangroves along the coast. Mangroves among the most carbon-rich forests in the tropics. Threats to Mangroves
A2 Geography
2. The places where fresh water intrusion is regular are conducive for mangrove growth. 6. … Mangroves support a wide range of ecosystem services Mangroves provide support to a wide range of neighboring ecosystems, including coral reefs, seagrass beds, mud flats and sand flats (UNEP, 2014). The Blue Carbon Initiative. In addition to sea level rise, climate change endangers mangroves via more frequent and intense storms and the associated storm surge, which can lead to inundation, tree mortality, and soil erosion6. Though the State was hit by cyclones and storms earlier, it was severe in 1967, a couple of years after perishing of cyclone resistant species,” said a local scribe. Mangroves have the ability to absorb up to four times more carbon dioxide by area than upland terrestrial forests (Donato et al., 2011).The remarkable traits of the mangrove ecosystem translate into a wide variety of goods and services that we benefit from. Degraded blue carbon ecosystems can shift from being a carbon sink to a carbon source. Designed for the professional or specialist in marine science, coastal zone management, biology, and related disciplines, this work will appeal to those not only working to protect mangrove forests, but also the surrounding coastal areas of all types. Threats To Mangroves 1. Mangroves range in size from small shrub-like bushes to the huge 60-meter (200 ft) specimens found in the province of Manabi, Ecuador. He also came down heavily on the coastal highway plan that has been finalised without proper study to assess the ecological impact. Mangrove forests offer significant protection from coastal erosion, storm surge, and sea level rise, all of which may lead to potentially devastating and life-threatening flooding along the coast. In the Florida Keys, human development is the greatest threat to mangrove communities. Environmental functions of mangrove ecosystems include nutrient supply and regeneration, recycling of pollutants, water cycling and the maintenance of water quality (Ruitenbeek, 1994). Available at: Wongthong, P. (2008). Historically, the primary threats to mangroves have come from conversion for aquaculture or … Latest threat to cyclone-resistant mangroves. The first line of defence is Psammophytes, which reduce the velocity of tidal waves on the sand-dunes along the coast. Most diversity of mangrove species is in Southeast Asia – with only around 12 species surviving in the Americas. ... Mangrove ecosystem aizadhassan. Mangrove status, values and threats . The vegetation found in such wetlands is specifically adapted to survive in the hydric soil of such areas. It is estimated that as much as 50% of mangrove coverage has been lost in the last half century alone1. Mangroves sudeshna . Nuagaon village under Kandira panchayat of Rajnagar block in Kendrapada district is one of the villages where the inhabitants have developed mangrove forests on over acres of land. The cleansing of mangroves from vast swathes of land has wider ecological consequences too. ... expressed deep concern over the destruction of mangrove ecosystem in the name of development projects and human intervention. A total of 73 mangrove species and hybrids are dispersed across 123 countries and territories around the globe (Spalding et al., 2010). Climate change and sea level rise impacts on mangrove ecosystems. Today, wetlands across the world are subjected to many threats. Over the past thirty years or so, Sri Lanka’s coastal zone has witnessed a rapid conversion of it’s mangroves for various uses such as aquaculture and housing development. Threats Status to the Mangrove Ecosystem Along the Coastal Zone of Yemen 107 Al-Haroonia Small patches (S15) of dispersed short mangrove trees are growing near fishermen village near Al-Haroonia. Mafie Falcon Recommended for you. Mangrove forests are among the most threatened habitats in the world, and mangrove loss is rampant across the globe. 13:55. Human-induced thermal, agrochemical, nutrient, heavy metal and oil-spill pollution also seriously impact this fragile ecosystem while deforestation and coastal development are o… This book focuses on the worldwide threats to mangrove forests and the management solutions currently being used to counteract those hazards. Mangrove trees grow ubiquitously as a relatively narrow fringe between land and sea, between latitudes 25°N and 30°S. It is satisfying that several villages have taken up initiatives to create and regenerate mangroves and the Government-sponsored eco-development committees work brilliantly to promote the endeavour, he added. The Forest Department is taking measures for the eviction of encroached land and to enhance mangrove cover. Mangrove forests are also deforested to make room for agricultural production, as well as coastal infrastructure. Besides, mangroves have a mechanism of multiple channels; so, when tidal waves with high intensity ingress into mangroves, they get distributed into several routes. Referring to a study report he added that mangroves sequester about 1,000 tonnes of carbon per hectare for over thousands of years. Apart from acting as a natural barrier to check the impact of sea rise and tidal waves, mangroves play a significant role in absorbing the toxic carbon responsible for global warming, Panda maintained. Cabahug DM Jr, Ambi FM, Nisperos SO, Truzan NC Jr (1986) Impact of community-based mangrove forestation to mangrove dependent families and to nearby coastal areas in Central Visayas: a case example. The latest in mangrove science, restoration and conservation. 13.3 FOREST STRUCTURE AND ECOSYSTEM FUNCTION 13.3.1 Mangrove-specific effects on nutrient dynamics. Beware of that cyber attack, Talktime | ‘Chhalaang was slated to do well’, ‘I’m enjoying the process of writing new songs now’. Mangrove extent was measured within a band from 1 km inland to 1 km seaward from the shore. Different types of snakes, fishes, shrimps and crabs are also sighted there. He said apart from working as a cyclone resistant, mangrove offers livelihood opportunities to many and provide firewood, food, fodder, clean water and raw materials for housing. They oppose the developmental projects as they would affect the species and the overall coastal ecosystem. There are several types of mangrove plant living in Antigua and Barbuda and as a life form they ares so unique and important that i think i will try to cover a tiny description here on this blog. Biodiversitas 21: 3625-3636. At present, about 1% of global mangrove coverage continues to be destroyed each year. Potential Impacts of Sea Level Rise on Mangroves. Opposing the Sagarmala project which aims at construction of shipping corridor at 20 nautical miles close to territorial waters, Odisha Traditional Fish Workers’ Union (OTFWU) general secretary K. Alleya during a Press meet recently said the project would destroy the marine ecosystem of the locality. Now the trees and shrubs have reached the height of about 7-8 feet. The great mangrove forest also falls along the delta of rivers like Ganges, Brahmaputra, and Meghna, and is a world heritage site for more than three decades. RSSocial! They come with multiple values for the communities and ecology. Threats to Mangroves: Natural threats to mangroves include hurricanes, root clogging from increased water turbidity, and damage from boring organisms and parasites. Another critical threat to mangroves is the fact that they are consistently undervalued in cost-benefit analyses and in the minds of policymakers, governments, local communities, and individuals. “Our climate actions have been too artificial ‘sea wall’ centric while in reality the natural solutions are cost effective and sustainable. Mangrove forests are being destroyed at an alarming rate, despite the many benefits and ecosystem services that they provide. Responsible Aquaculture. “Paradip was once a mangrove swamp, used largely by locals for hunting, fishing and firewood. Regeneration capacity and threats to mangrove areas on the southern coast of Oriental Mindoro, Philippines: Implications to mangrove ecosystem rehabilitation. He further said nature has a three-layered mechanism to reduce sea rise and storm. Donato et al. High deforestation rates, improper solid-waste management, rapid coastal development, increasing poverty, weak institutional and legal frameworks, and the recent discovery of sweet crude oil all pose significant threats to Belize's ecosystem. Impacts of Climate Change on Mangrove Ecosystems Sea level rise Processes contributing to mangrove vulnerability to sea level rise Sea level rise is a major potential climate change threat to mangrove ecosystems, because mangroves are sen- We then assess the relative vulnerability (sensitivity, exposure, and adaptive capacity, Glick and Stein 2010 ) of mangrove regions to these climate change impacts. Fishermen will not be able to fish in the deep sea once the project is complete, he added. It is also estimated that if these destructive trends are allowed to continue, all unprotected mangroves will be lost within the next century2. Sea-level rise degrades mangrove ecosystems through sediment erosion, inundation stress, and over-salinization4. The construction of upstream dams and irrigation systems also contribute to mangrove destruction, as they alter the water flow and can lead to over-salinization and lack of new sediment input. Blue Carbon. Biraja Prasad Pati, a social activist, who is instrumental in mobilising the villagers of Nuagaon to create mangroves, expressed deep concern over the destruction of mangrove ecosystem in the name of development projects and human intervention. Power point presentation on protection of mangroves from destruction and degr... Navanitha Warrier. They form forests of salt-tolerant species, with complex food webs and ecosystem dynamics (Macnae 1968, Lugo and Snedaker 1974, Tomlinson 1986). Mangroves face numerous threats to their existence, the most imminent of which are human-induced. 3:42. As a result, mangrove ecosystem services will gradually be reduced: The structure will prevent the mangroves’ natural landward migration and the mangrove fronting the structure, as well as immediately downstream in the direction of longshore sediment transport from the structure, will eventually be converted to deepwater habitat (Tait and Griggs, 1990, Fletcher et al., 1997, Mullane … 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. However, our planners still don’t pay them the due importance they deserve.”. Accessed on November 15, 2016. It also checks the wind velocity thwarting the effect of tropical storms. Loading ...

Prasad K Dash, a botanist of Odisha Biodiversity Board, said, “The intricate network of mangrove roots help reducing the intensity of high tidal waves. This mangrove patch has played a role in checking the cases of human-crocodile conflict by offering shelter to the reptiles that often stray into the village from river Hansua,” added Biraja. Villagers guard the plantation site on turn basis to protect the trees. (2011). Extent per oceanic region was reported in km 2 per country. In: National Mangrove Committee (ed) Mangroves of … 1986). He flayed the shortsightedness of the authorities involved in the port expansion project under Sagarmala. The shallow waters of the Bay of Bengal, existence of multiple deltas and river mouths form a conducive atmosphere for the growth of mangroves, the botanist explained. It is estimated that as much as 50% of mangrove coverage has been lost in the last half century alone1. So, what else threats to ocean ecosystems? D espite the valuable role that mangroves and seagrass play in the Florida Keys ecosystem, these plants are facing one particularly large threat: Us.. Mafie Falcon 11,315 views. Agricultural and urban runoff, along with other forms of pollution, including oil spills, contribute significantly to mangrove degradation. Urban Development Urban development of areas in and near mangroves results in the destruction of this habitat as well as other associated wetland habitats. Assistant Conservator of Forests, Mahakalpara Range, Bijay Kumar Parida maintained that apart from developmental projects, encroachment by the villagers (for homestead and agriculture land) and setting up of prawn gheries cause massive damage to the mangroves and the coastal ecosystems. Such carbon sinks are called the blue carbon ecosystems. Mangrove forests are incredibly important ecosystems. But a major part of that cover was cleared for establishment of the port in the 1960s. Mangrove forests are being destroyed at an alarming rate, despite the many benefits and ecosystem services that they provide. A rapidly growing global population, coupled with an ever-increasing coastal population expansion, means that many coastal communities are rapidly urbanizing, often without proper development planning, and coastal ecosystems are bearing the brunt. HARSHIT DWIVEDI 153 views. Talking about mangroves in mitigating the impact of climate change, water and climate expert Ranjan Panda said, “Mangroves help us in both mitigating climate change and adapting to its impacts. Our behavior in daily life can make threats to ocean systems, below here is activity in our daily life and it can be threats to our ocean ecosystem. This reduces the rate of soil erosion and offers shields to the coastal communities against tidal waves. A globally rare yet highly threatened coastal forest ecosystem, mangroves cover approximately 137,760 km 2 – 152,360km 2 of the world’s surface (Kainuma et al., 2013). A major threat to the mangrove forest. They observed that the places with mangrove cover suffer less damage to life and property, whereas the places where the cover was destroyed suffered heavy damage. Litter produced in the canopy of mangrove forests influences the cycling of inorganic nutrients on the forest floor, and the outwclling of organic matter to adjacent coastal waters (Figure 13.5) (Odum and Heald 1972; Twiliey et at. Any further delay would not only mean huge loss of livelihood of a large number of coastal communities, but also make us more vulnerable to devastations caused by the increasing number of cyclones caused due to climate change,” Panda added. el ecosystem with which to study these questions over inter-regional and global scales. Header: ©Ethan Daniels/TNC Other long patches of mangrove habitats grow in several places about 70-85 m far from the shoreline between Ibn Abbas and Al-Haroonia villages. Threats I Mangroves for Future Initiative - Duration: 13:55. Although very complex and resilient to natural disturbances, mangrove ecosystems worldwide are endangered by human activity and are lost at a greater rate than inland tropical forests. Threats to Mangrove Ecosystems Published: 24 January 2019 Vast expane of Nypa palms (Nypa Fructicans). Since the 1950s, more than 60 percent of mangroves in Monroe County have been destroyed for development.
