A heat map of the planet showing methane emissions from wetlands from 1980 to 2021. Greenhouse gas emissions from wetlands of concern consist primarily of methane and nitrous oxide emissions. Wetlands are the largest natural source of atmospheric methane in the world, and are therefore a major area of concern with respect to climate change.
Wetlands play a crucial and multifaceted role in mitigating climate change through their natural processes and functions. [10] They capture carbon from the air when plants grow and trap sediment from water. This carbon gets stored in plants, leaves, soil, and mud, sometimes for thousands of years. [11]
Article 2.1: "[Wetlands] may incorporate riparian and coastal zones adjacent to the wetlands, and islands or bodies of marine water deeper than six meters at low tide lying within the wetlands." An ecological definition of a wetland is "an ecosystem that arises when inundation by water produces soils dominated by anaerobic and aerobic processes ...
Data published in March 2023 in Nature Climate Change shows that annual wetland emissions over the past two decades were about 500,000 tonnes per year higher than what scientists had projected ...
Climate change is not the only danger to Tunisia's wetlands, he said. Cities and towns are growing closer to the edges of lagoons and rubble and waste are ever more often dumped in or near the water.
Wetlands exist on every continent, except Antarctica. [19] The water in wetlands is either freshwater, brackish or saltwater. [18] The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds, cattails and sedges.
A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants , adapted to the unique hydric soil .
Ecosystem-based Adaptation (EbA) describes a variety of approaches for adapting to climate change, all of which involve the management of ecosystems to reduce the vulnerability of human communities to the impacts of climate change such as storm and flood damage to physical assets, coastal erosion, salinisation of freshwater resources, and loss of agricultural productivity.
