WETLANDS Meaning and
Definition
-
Wetlands are defined as transitional lands between terrestrial and aquatic ecosystems, characterized by the presence of wet or saturated conditions for a significant portion of the year. These unique ecosystems play a crucial role in the hydrological cycle, acting as filters and buffers, absorbing and holding water during periods of high rainfall or flooding, and slowly releasing it during drier periods.
Wetlands are typically characterized by the presence of water-saturated soils, hydrophilic vegetation, and frequent inundation. They can be found in various places such as marshes, swamps, bogs, and floodplains, both inland and along coastlines. Due to their specific hydrological characteristics and the wide variety of landforms and vegetation they host, wetlands provide habitat for diverse communities of plants and animals, including specialized species that are dependent on wetland conditions.
These ecosystems offer numerous ecological services, including regulating water flow, improving water quality through filtration and nutrient cycling, providing habitat for a wide range of organisms, and supporting biodiversity. Wetlands also act as carbon sinks, helping mitigate climate change by sequestering carbon dioxide. Additionally, they provide recreational opportunities, such as birdwatching, canoeing, and fishing, and contribute to the cultural heritage of many communities.
However, wetlands are facing significant threats due to human activities, including drainage for agriculture, urban development, pollution, and climate change impacts, leading to a decline in their extent and health globally. The conservation and restoration of wetlands are vital to maintain their ecosystem services and conserve the biodiversity they support.
