Although the area of coastal wetlands is rather small compared to many other terrestrial ecosystems, their productivity is comparable to the most productive ecosystems. 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. 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. In the Bohai Bay of Northern China, a sharp decline of fishery resources has been witnessed as a result of wetland loss and pollution from inorganic nitrogen and phosphorous, oil, and heavy metals, which greatly decreases the food available to migratory birds (, Chinas coastal wetlands have an area of 5.8 million ha, supporting 230 waterbird species, which is about 25% of the global total.

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. . The pressure to convert lands into resource areas for producing priced foods, crops, and livestock rearing has increasingly led to the depreciation of natural environments such as forests, wildlife and fertile lands. Available from. 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). L G.H., Zhou L., Zhao X.L., Jiao Q.Y., Xie Y.B., and Zhou G.S. The effects of grazing on Wright's marsh thistle depend on timing.

Estuar. 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. Wetlands Destruction - FLOW Understanding and predicting wave erosion of marsh edges. Wetlands. Wetlands destruction has increased flood and drought damage nutrient runoff and water pollution and shoreline erosion and triggered a decline in wildlife populations. Wetlands. Human activities can also increase the extent of wetlandsfor example, by creating shallow ponds or re-establishing formerly drained wetlands on farmlands.

But they are almost always terrible places to build houses. Das S. and Vincent J.R. 2009. Unfortunately, many remaining wetlands are in poor condition and many created wetlands fail to replace the diverse plant and animal communities of those destroyed. Leonardi N. and Fagherazzi S. 2015. We also have thousands of examples of restored wetlands. 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).

Also, environmental degradation aspects such as deforestation and mining destroy the natural land cover. Coastal marsh die-off and reduced attenuation of coastal floods: a model analysis. According to a study about tree density published in Nature, the number of trees worldwide has decreased by 46 percent since the start of civilization. Throughout history, there have been many historical events that, according to the dominant ideas or economic needs of the time, have modified and/or eliminated entire ecosystems. 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. One of them is removing trees and plants. Li X.Z., Ren L.J., Liu Y., Craft C., Mander U., and Yang S. 2014. Rethinking Chinas new great wall. In the Western world, changes in land use have resulted in the loss of many wetlands. Wetlands include trees, grasses, shrubs, moss, and other plants that require at least some water coverage. 0000004816 00000 n The condition of wetlands reflects a combination of physical, chemical, and biological attributes. Intensive agricultural practices destroy fertile lands and nearby vegetation cover due to the accumulation of toxic substances like bad minerals and heavy metals which destroy the soils biological and chemical activities. In Spain, we know from historical documents the enormous importance of hundreds of thousands of wetlands that populated the territory of the Iberian Peninsula.

The clearing of land for farming, grazing, mining, drilling, and urbanization impact the 80 percent of global species who call the forest home. Available from, Worldwatch Institute. The effects of soil erosion go beyond the loss of fertile land. Environmental degradation can alters some of the natural process such as the water cycle and the normal processes of animal and plant activities. First, the reduced flooding prevents deposition of overbank sediments that are vital to land-surface aggradation and wetlands maintenance. Coast. Some of the reasons for deforestation include farming, construction, settlement, mining, or other economic purposes. 2010. Coastal Wetland Habitat | NOAA Fisheries Besides, occurrences such as hurricanes and flooding can wash or force the migration of invasive species into foreign environments which can lead to its eventual degradation. Successful restoration requires both semi-natural vegetation structure and a high diversity of fauna groups, to ensure multi-functionality of the restored ecosystem. 2011. 1993. Geophys. 1987. Nat.

Geophys. According to theBrookings Institute, restoration of the Great Lakes will create economic benefits of at least $50 billion and create thousands of jobs. Copyright Maryland.gov. In many cases, the ocean-front block of these islands is 5 to 10 feet above high tide; but the bay sides are often less than two feet above high water and regularly flooded. Impacts of biodiversity loss on ocean ecosystem services. 2016. Winter grazing (after seed dispersal and before seedling growth in spring) probably has a low effect on survival and reproduction, although there could be some trampling of rosettes, while spring and early summer grazing probably reduces growth, survival, and reproduction.

Evaluation of ecosystem health for the coastal wetlands at the Yangtze Estuary, Shanghai. As a result, this caused the massive disappearance of many wetlands. Causes of Environmental Degradation. 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. Geophys. The Great Lakes watershed has lost 62 percent of its original wetlands, and some parts of this region have lost more than 90 percent of these habitats. PDF What Is the Status of Our Nation's Wetlands? - US EPA Diverting water can harm mangroves by preventing their seeds from being dispersed via seawater, and it can kill the trees by cutting off freshwater supplies. A larger gap is the lack of an indicator on wetland condition. In fact, 80% of the worlds large deltas have experienced severe flooding in the last decades (, Moreover, degradation caused by saltwater intrusion, drought, and pollution are also threatening the health of coastal wetlands (. One of the calamitous effects of landfills is the destruction of nearby environmental health together with its ecosystems. Majority of farmers resort to converting forests and grasslands to croplands which reduces the quality of natural forests and vegetation cover. Lett. Incorporating ecosystem services into coastal planning will achieve greater returns from coastal protection and tourism than from achieving conservation or development goals only (, Moreover, while faced with quick economic development along the world coast zones, we also need to make room for potential sea-level rise.
