Point sources, such as municipal industrial sites, and non-point sources, such as agricultural lands and urban runoff, add materials to ground water and surface water that upset the balance of wetland water chemistry and the biogeochemical cycling of materials in wetland ecosystems. Most of the planets natural environments have been destroyed and a large portion is under huge threat due to the toxic substances and chemicals emitted from fossil fuel combustions, industrial wastes, and homemade utilities among other industry processed materials such as plastics. Environ. Federal Register :: Endangered and Threatened Wildlife and Plants Coastal wetlands, which lie between the land and the ocean, are threatened from both human activity and natural hazards, such as climate change, sea level rise, local subsidence, decreased sediment supply, and acidification. Science, Vaidyanathan, G. 2011 Blue carbon plan takes shape. 0000095675 00000 n But the production of Chinese fishery is mainly from aquaculture (>70%) (, Coastal wetland reclamation often results in the destruction of spawning and nursery ground for many marine species, while birds lose their food and shelter with more disturbed habitats. Sediment budgets and ratios of mud, sand, and organic matter in the soil of deltaic plain are generally unknown, yet are crucial for preventing drowning (, From an academic point of view, the challenge for coastal wetlands restoration is also a great opportunity for landscape ecologists to transfer their knowledge into practice.

Lavery P.S., Mateo M.-., Serrano O., and Rozaimi M. 2013. Rethinking Chinas new great wall. 2nd ed. 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. Res. For example, the average net primary productivity of mangroves is as high as that of the tropical rain forest (2.2 kgm, As key habitats for many terrestrial and marine species, vegetated zones and tidal creeks provide diverse shelter and food sources for a large variety of wild animals, resulting in high biodiversity and unique food webs. The amount of newly created wetlands, however, will be much smaller than the area of wetlands that are lost. Unfortunately, the vast coastal wetlands are seriously threatened by the 11000km long Great Seawall, or 60% of the Chinese coast line (, The losses of biodiversity result in the damage of some critical coastal ecosystem services, such as fishery, nursery habitats, and filtering and detoxification services, which further contribute to the decline of water quality and increase of harmful algal blooms, oxygen depletion, and mortality of benthic and nekton fauna (, Clearing of mangroves and subsequent excavation of the substrates for aquaculture ponds could result in the potential oxidation of 1400 t C ha, While coastal wetlands are facing loss, many countries have started taking measures to rebuild marshes with dredged sediments, or divert the river channels to elevate ground surface. When wetlands are drained, or even partly drained, the local drainage area is connected to downstream . Biogeochemistry: an analysis of global change. Although these structuress protect property, they can eliminate beaches, particularly bay beaches, which are usually less than 10 feet wide. The purpose of this paper is to provide a comprehensive understanding of the importance of coastal wetlands, their current status of losses and consequences at different regions, and challenges faced for restoration. In IUCN, sea intrusion in the coastal and riverine tracts of the Indus Delta a case study. Rev. Their microbial activity enriches the water and soil with nutrients. 2014. He Q. and Silliman B.R.

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. 2 What are 3 major causes of degradation and loss of wetlands? Wetlands regulate, capture and store greenhouse gases. 0000001096 00000 n Wetlands restoration is a major component of the overall Great Lakes Restoration Initiative. Coastal management: wetland issues in integrated coastal zone management. 2002. 0000002573 00000 n 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. Well tell you below. 2015. 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).

Ramsar Convention Secretariat, Gland, Switzerland. Destruction of wetlands is also detrimental to our regions economy: recreation like fishing, hunting, and wildlife watching generate more than $22 billion annually. In the past, the societal and ecological value of wetlands were not widely recognized and many wetlands were destroyed. Sci. Geophys. This, together with air, water, and land pollution pose several atmospheric alteration threats. 600 pp. Duarte C.M., Middelburg J.J., and Caraco N. 2005. Wetlands, or marshes, fens, bogs, and swamps, are the link between land and water. 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. The dry land, or uplands, within a few feet above high tide includes forests, farms, low parts of some port cities, parts of deltas, and the bay sides of barrier islands. Wetlands are a relatively rare ecosystem, but are nevertheless very important. Making sure the Michigan Department of Environmental Quality applies and enforces the law is a duty of every citizen. Coastal wetlands of the world: geology, ecology, distribution and applications. 2006. 2010. Ecol. There are many forms of habitat loss. Common direct impacts to wetlands include filling, grading, removal of vegetation, building construction and changes in water levels and drainage patterns. About two-thirds of marine animals, such as fish, shrimps, crabs, mollusks, and turtles, have to spend some time at coastal wetlands during their life history, and over 90% of marine fisheries are sourced from coastal zones, either through harvesting of wild organisms or mariculture (, In terms of carbon sequestered in the soil or sediments of different ecosystems, the mean long-term rates of carbon sequestration for salt marshes, mangroves, and seagrasses (>100g C m, Carbon sequestration by mangroves, salt marshes, and seagrass beds is highly variable with estimations of combined global rates ranging between 0.23 and 0.77 Pg CO, Like the organic carbon in terrestrial ecosystems, most of the organic carbon in coastal wetlands is stored underground and insufficiently investigated (. Profiling risk and sustainability in coastal deltas of the world. Wetland losses around the world are truly dramatic. Natl. Brambati A., Carbognin L., Quaia T., Teatini P., and Tosi L. 2003. 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. Under storm surge conditions, marsh vegetation can reduce wave energy by 60% (, The vegetated zone can also trap enormous amount of sediments, helping survival of salt marshes with land accretion horizontally and vertically (, The functions and services presented here demonstrate the indispensable value of coastal wetlands.
