Explain in detail why wetland soils are a good carbon pool (must include, Introduction, body and conclusion).
A wetland is a place where the land is covered by water. Marshes, ponds, the edge of a lake/ocean, the delta at the mouth of a river, low-lying areas that frequently flood — all of these are wetlands.
Wetlands of international importance are also known as Ramsar sites
Many researches have been conducted to remove carbon dioxide from the atmosphere to mitigate the effects due
to climate change. One of the initiatives is augmenting the use of wetlands. Wetlands are areas of mainly water saturated soil, including marshes, lakes and floodplains. Wetlands play a major role in the global carbon cycle because they are an important carbon sink for atmospheric carbon dioxide. They also provide many beneficial ecosystem services to humankind, for example, water quality improvement, flood mitigation, wildlife and coastal protection .Wetlands have also been estimated to store 20-30 % of the earth’s soil pool of 2,500 Pg of carbon and carbon from the atmosphere due to their anoxicwet conditions . Furthermore, wetlands have the highest carbon density among all other terrestrial systems.
There have been 3.7 times faster rate of wetlands loss during the 20th and early 21st centuries, with a loss of 64-71% of wetlands among the world since 1900 AD (Davidson 2014). The increasing rate of natural wetlands loss has led to more creation of constructed wetlands which were intended to emulate the functions and values of natural wetlands that have been destroyed. Constructed wetlands aim to provide an ecosystem to counter balance natural wetlands that have been converted for agriculture and urban development, improving water quality, controlling floods and producing food and fibre. Constructed wetland systems have been adopted and applied successfully for the purification treatment of many wastewater since 1980
