It is widely recognised that wetlands play an important role in the hydrological cycle, influencing groundwater recharge, low flows, evaporation and floods. USA. Reduction in air quality is responsible for more than 300,000 deaths annually and millions of chronic diseases. Reduction in water quality is responsible for more than two million deaths and billions of illness annually across the globe. Nat. Liu B.Q., Meng W.Q., Zhao J.H., Hu B.B., Liu L.D., and Zhang F.S. Condition is difficult to measure because it is made up of many different attributes, and each wetland has its own unique baseline condition, function, hydrology (water flow), and combination of plant and animal species. Estuar. 1800 Washington Blvd., Baltimore, MD 21230, A Method for the Assessment of Wetland Function, A Comprehensive Nontidal Wetland Watershed Management Plan: A Guide for Local, Wetlands and Waterways Permits Interactive Search Portal. Geophys. 2014. Along tidal rivers and in extremely flat areas, floods can be caused by storm surges from the sea or by river surges. The highest rates of wetland loss occurred between the 1950s and the 1970s, until conservation movements considerably slowed the rate of decline [source: EPA]. Res. Altogether, the toxic wastes and harmful chemicals from factories, agriculture and automobiles cause illnesses and death in children and adults. [1] Dahl, T.E. Sinking deltas due to human activities. Wetlands destruction has increased flood and drought damage, nutrient runoff and water pollution, and shoreline erosion, and triggered a decline in wildlife populations. ' The effect of bioenergy expansion: Food, energy, and environment ', Renewable and Sustainable Energy Reviews 32 (C), 559-578. Future flood losses in major coastal cities. Second, the reduced freshwater inflow allows saltwater encroachment, which kills the fresh . In Spain, we know from historical documents the enormous importance of hundreds of thousands of wetlands that populated the territory of the Iberian Peninsula. Many wetlands were reclaimed for other use (e.g., agriculture) before their significance was recognized. 2017. Without wetlands, cities have to spend more money to treat water for their citizens, floods are more devastating to nearby communities, storm surges from hurricanes can penetrate farther inland, animals are displaced or die out, and food supplies are disrupted, along with livelihoods. Estuar. In addition to the loss of habitat, deforestation reduces the ability of forests to provide the critical benefit of absorbing carbon, which helps to mitigate the effects of climate change. The effects of grazing on Wright's marsh thistle depend on timing. :F 1fcE?) >yX7>Nnono~Gl2=_/! =@]"!N{,@(. 298 pp. 2015. Williams P.B. 4th ed. Evaluation of ecosystem health for the coastal wetlands at the Yangtze Estuary, Shanghai. Types of Wetland ImpactsHuman ImpactsNatural ImpactsTypes of Wetland Impacts, Sources of pollution have local and regional effects on the chemistry and quality of water flowing through wetlands. Biol. Approximately half the Nation's original wetland habitats have been lost over the past 200 years. Coastal wetlands provide important services, such as food and bio-materials as direct resources, habitat for wildlife, carbon sequestration, protection against storm surges, and sediment accumulation for land accretion. Yee A.T.K., Ang W.F., Teo S., Liew S.C., and Tan H.T.W. 2010. They can't replace the diagnosis, advice, or treatment from a professional. Clim. Wetlands are ecosystems that are periodically or permanently flooded with shallow water. 2015. They are also on the migration routes of 19% of the globally threatened migratory bird populations. Res. Salt marsh restoration experience in San Francisco Bay. Natl. #Maandamano Nairobi CBD Shakahola Annex . 0000095675 00000 n Because many US recreational beaches are less than 100 feet wide at high tide, even a 1 foot rise in sea level would threaten homes in these areas. The Maryland General Assemblys Office of Legislative Audits operates a toll-free fraud hotline to receive allegations of fraud and/or abuse of State government resources. 10.1016/j.rser.2014.01.056 [Google Scholar] Habitat loss is primarily, though not always, human-caused. Contributing to food security and nutrition for all. It can be influenced by many natural and human-induced stressors. Since 1990, just over 15% of the original area has been recovered. 2002. Embedding ecosystem services in coastal planning leads to better outcomes for people and nature. Sea level rise is thought to be one of the potential threats for coastal wetlands; it is still controversial because wetlands can migrate landward if no seawall or steep relief exists behind the wetlands, but this is often not the case. Despite all those and other indispensable values, these wetlands are under severe pressure and degradation. Coast. Hinrichsen, D., and Olsen, S. 1998. Wetlands help prevent erosion in 2 ways: 1) Wetland plants serve as a physical barrier by taking the punishment of the waves crashing into shore or the water running down a hill. Kirwan M.L., Temmerman S., Skeehan E.E., and Guntenspergen G.R. 0000008710 00000 n Besides the foul smell from the landfills and periodic burning of the wastes make living in such environments unbearable. 2013. Li X.Z., Ren L.J., Liu Y., Craft C., Mander U., and Yang S. 2014. Most traditional uses of wetlands do not impose permanent impacts, with the exception of livestock grazing and timber harvest which can affect the functions such as water quality and habitat. Louisiana Barrier Island Comprehensive Monitoring Program (BICM) Volume 2: Shoreline changes and barrier island land loss 1800s2005. J. Meteorol. Some wetlands go through seasonal changes. PLoS ONE, Coastal Wetland Planning, Protection and Restoration Act (CWPPR). Intensive agricultural practices have led to the decline in quality of most of our natural environments. The landfills discharge various kinds of chemicals on the land adjacent to forest, various natural habitats, and water systems such as underground and surface water which makes the environment unappealing to the survival of trees, vegetations, animal and humans. And degraded lands are also often less able to hold onto water, which can worsen flooding. 417 pp. Lett. 1997. For example, considering the Midwest of the United States alone, some studies estimate that from 1850 to 1930, humans drained a minimum of 125 million acres of wetlands for agriculture. 0000079759 00000 n Natl. The buffer function for pollutant degradation, erosion, and land subsidence will be lowered, with increased risk from storm surge and flooding. Nicholls R.J. and Cazenave A. In part, this has been a result of natural evolutionary processes, but human activities, such as dredging wetlands for canals or draining and filling for agriculture, grazing, or development, share a large part of the responsibility for marsh habitat alteration and destruction. Another type of habitat destruction is habitat degradation. Sci. Some new concepts, such as building with nature (, Along the Shanghai coast, to facilitate salt marsh restoration out of the strongly armored seawall, a low levee near the 0m elevation was constructed and muddy water was pumped into the space between the two levees, so that natural vegetation can establish and eventually encroach into the tidal flat outside the low levee (, In the Mississippi River Delta, a project called the Coastal Wetland Planning, Protection and Restoration Act has been implemented since the 1990s (, An example of living shorelines is to use shellfish aquaculture as a management strategy for nitrogen reduction and bank protection (, The first project of wetland restoration in San Francisco Bay was enacted in 1972, after losing 90% of its marshes from the beginning of American colonization (, The San Francisco Bay restoration efforts provided a series of lessons, such as (, The Dutch people have implemented the approach of building with nature for years by nourishing the coast with sediments from the North Sea (, Restoration of mangroves with plantations has been achieved in Thailand, Vietnam, China, and other countries. Mitsch, W.J., and Gosselink, J.G. One of the most emblematic is in Spain, specifically in the Nava lagoon in Palencia. It even interferes with the animals interactive food chains because the chemicals contaminate plants, and waters which are consumed by the animals. Available from, Ong, J.E. The clearing of land for farming, grazing, mining, drilling, and urbanization impact the 80 percent of global species who call the forest home. #MaandamanoTuesday will begin at 6;00am no matter the case! Before the 20th century, this lagoon was one of the most important wetlands on the Peninsula, covering almost 5,000 hectares during the wet season. Wetlands restoration is a major component of the overall Great Lakes Restoration Initiative. Lavery P.S., Mateo M.-., Serrano O., and Rozaimi M. 2013. Poffenbarger H.J., Needelman B.A., and Megonigal J.P. 2011. With sufficient funding and political will, the loss of wetlands due to man can be restored. Reg. Cambridge University Press, New York, N.Y., USA. Conversion to agricultural use was the primary cause for most of the losses, but urbanization, reservoir construction, highway construction, and other activities also contributed. 01 May 2023 17:41:18 Continued environmental degradation can completely destroy the various aspects of the environment such as biodiversity, ecosystems, natural resources, and habitats. 2nd ed. Studies reveal that by protecting 50 percent of the land and ocean around the world, plant and animal species could thrive. Revista Ecosistemas,13(2). Regional decline of coral cover in the Indo-Pacific: timing, extent, and subregional comparisons. UN Climate Change News, 01 October 2018 - Wetlands, amongst the world's most economically valuable ecosystems and essential regulators of the global climate, are disappearing three times faster than forests.. The total decline of wetland since 1978 is estimated at 41,000 acres, with the rate of decline slowing between the periods 1978 to 1998 (loss of approximately 1,642 acres per year) and 1998 to 2005 (approximately 1,157 acres per year). Planet. Ecol. For years, people have drained or filled wetlands for agriculture or development, causing habitat loss as well as a decline in many other important wetland functions. Coastal wetlands are continuously lost under pressure of several problems such as human activities, lack of data and climate change. Building land with a rising sea. The unplanned conversion of lands into urban settings, mining areas, housing development projects, office spaces, shopping malls, industrial sites, parking areas, road networks, and so on leads to environmental pollution and degradation of natural habitats and ecosystems. However, the vast majority of wetland losses and gains over the last . 0000097967 00000 n DAlpaos A., Mudd S.M., and Carniello L. 2011. An effective strategy for protecting coastal wetlands includes a coastal marine spatial planning effort focused on the shared goal of identifying future competitive uses and impacts. 5 How does a wetland help to prevent erosion?

Environmental Defense Fund. The world coastal wetland lost more than 50% of its area in the 20th century, largely before their great value, such as wave attenuation, erosion control, biodiversity support, and carbon sequestration, was fully recognized. Spatial variation of salt-marsh organic and inorganic deposition and organic carbon accumulation: inferences from the Venice lagoon, Italy. Bull. 2014. Change. wetlands and aquatic life. On this regard, degradation means damage or reduction in quality of environmental features, primarily influenced by human activities. and Faber P.B., 2001. This is because of the human activities such as acidifying water systems, over-exploitation of natural resources, overpopulation, and the deliberate and indirect destruction of natural systems necessary for the survival of different species. When wetlands are filled, the water that made them wet has to go somewhere. The data obtained from interviews were concerned with the causes of wetland destruction, condition of wetland and threat to the wetland in Makhitha village. It is a critical time to take actions to avoid further loss of this precious ecosystem with many important functionalities, and to restore it wherever possible. . Mar. Geophys. Macmillan Publ. According to a study by the UNEP Global Environment Outlook, excessive human consumption of the naturally occurring non-renewable resources can outstrip available resources in the near future and remarkably destroys the environment during extraction and utilization. An official website of the United States government. Habitat destruction, defined as the elimination or alteration of the conditions necessary for animals and plants to survive, not only impacts individual species but the health of the global ecosystem.
