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. All rights reserved. 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. Hostile shores: migratory bird populations in Asia are crashing as Yellow Sea habitat dwindles. Today, only 15 percent of the land and 7 percent of the ocean is protected, leaving us with a challenging yet attainable goal. Ecol. Mitsch, W.J., and Gosselink, J.G. The condition of wetlands reflects a combination of physical, chemical, and biological attributes. Available from. Educating and organizing your community to enact and/or enforce an ordinance is another way of stopping wetland destruction. 2012. 0000001613 00000 n Once again, twentieth-century developmental plans wiped out biodiversity and the lagoon was drained in 1968 for agriculture. 0000060887 00000 n A larger gap is the lack of an indicator on wetland condition. Wetlands' highly developed root systems hold the soil in place and filter pollutants, naturally improving water quality (including water that is eventually used for drinking). Although these structuress protect property, they can eliminate beaches, particularly bay beaches, which are usually less than 10 feet wide. Causes of Environmental Degradation.

Erosion threatens the high ocean sides of these densely developed islands and is generally viewed as a more immediate problem than inundation of their low bay sides. Norwegian Institute for Water Research, Bergen N-5006, Norway. This means that urgent description of these causes is needed to . Overpopulation simply means more pollution and fast extraction of natural resources compared to how they are being replaced. 2017. [1] Dahl, T.E.

Hallegatte S., Green C., Nicholls R.J., and Corfeemorlot J. 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. Such failures usually occur during spring months when the soil water conditions are most conducive to the problem. In Spain, we know from historical documents the enormous importance of hundreds of thousands of wetlands that populated the territory of the Iberian Peninsula.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 EPA also list the following as major human causes of wetland loss: logging, runoff, air and water pollution, introducing nonnative species. In the majority of developing countries, poverty is attributed to poor crop harvests and lack of quality natural resources that are needed to satisfy basic survival needs.

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. 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 .
