The channels of air-filled cavities (see image to right) provide a low-resistance internal pathway for the exchange of gases such as oxygen, carbon dioxide, and ethylene between the plant above the water and the submerged tissu

Peatlands arise because of incomplete decomposition of organic matter, usually litter from vegetation, due to water-logging and subsequent anoxia. Peatlands are unusual landforms that derive mostly from b

The term is of Arabic origin and specifically refers to oases that emerge in rocky landscapes in Arab regions, particularly in countries like Algeria and Saudi Arabia. thumb|Guelta de Tikoubaouine, Tassili n'Ajjer, [[Algeria]] A guelta is a natural water pool that forms in rocky basins and often serves as a crucial water resource in arid regions.

A dambo is a class of complex shallow wetlands in central, southern and eastern Africa, particularly in Zambia, Malawi and Zimbabwe. They are generally found in higher-rainfall flat plateau areas and have river-like branching forms which in themselves are not very large but combined add up to a large area. Dambos have been estimated to comprise 12.5% of the area of Zambia. Similar African words include mbuga (commonly used in East Africa), matoro (Mashonaland), vlei (South Africa), fadama (Nigeria), and bolis (Sierra Leone); the French bas-fond and German Spültal have also been suggested as re

Telmatology is a branch of physical geography concerned with the study of wetlands, such as marshes or swamps.

Paludiculture is wet agriculture and forestry on peatlands. Paludiculture combines the reduction of greenhouse gas emissions from drained peatlands through rewetting with continued land use and biomass production under wet conditions. "Paludi" comes from the Latin "palus" meaning "swamp, morass" and "paludiculture" as a concept was developed at Greifswald University. Paludiculture is a sustainable alternative to drainage-based agriculture, intended to maintain carbon storage in peatlands. This differentiates paludiculture from agriculture like rice paddies, which involve draining, and therefor

A hamun (or hamoun) ( hāmūn) is an inland desert lake or marshland formed as a natural seasonal reservoir in areas adjoining the Helmand basin, found across eastern Iran, southern Afghanistan and western Pakistan. Hamuns form a critical link in the wildlife of the area, aquatic as well as avian and terrestrial.
