Wetland Mitigation: A Failing Attempt at Saving the Wetlands

Little little-known guardian of surrounding cities, fish, plants, many retreats of animals, and a unique recreational area for locals and attractive charm for the tourism industry - wetlands for us For us it is inevitable, unrecognizable value to society. Relaxation of wetland began to spread in the latter half of the 1980s, there was no net loss target, but the agency concerned was far from approaching this goal. - Sadly, wetlands are disappearing at overwhelming speed; according to Esty, the United States loses about 60,000 acres of wetlands each year (Esty).

Land selection - Project land sites are usually selected (relaxed) based on policies that require repair or construction of wetlands to compensate for the loss of available sites or neighboring wetlands. The wetland's ability to structure, function and duration will depend greatly on its location. Wetlands in environments where human activities are restricted may differ greatly in structure and function from wetlands controlled by human activities. Therefore, when selecting a site, you need to consider the current and predicted land use of the surrounding area. As an expected model for project wetlands, you can use the characteristics of existing wetlands in the same wide area or areas with similar land use. If paying attention to land selection, you can gain benefits beyond wetland itself from the arrangement of wetlands.

Traditional greenhouse gas reduction policies ignore the role of the world wetlands in methane (CH4) emissions in climate change related feedback. Here we use a series of climate predictions and biogeochemical methane models including dynamic wetland areas and permafrost to determine wetland feedback and how much wetlands exceed the CH4 emissions of the artificial 21st century Examine. Our results show that the new contribution of global wetland CH4 emissions is primarily related to the sensitivity of methane emissions to temperature and the change in wetland area of ​​the world. We emphasize that feedback from wetland CH4 on climate change and radiation compulsion is an important part of climate change and should be reflected in policies aimed at keeping global warming below 2 ° C .
