WETLANDS: REFLEXÕES TEÓRICO-CONCEITUAIS ACERCA DO ESTABELECIMENTO DE ÁREAS ÚMIDAS EM TERRAS SECAS

The wetlands (WL) in dry lands are distributed for various regions of the planet, have varied sizes and shapes/structures. Their physiographic dynamics results from a combined action and from the interaction game between the natural components that constitute them. In the context of the areas subject to arid and semi-arid climates, the WLs show a singular diversity of landscapes and for the supplied moisture, they function as access points to populations residing in the vicinity, as well as shelter for different animal species, specially in the dry periods. In this bias, the objective of this work is to weave a theoretical approach about the conceptual aspects and, the dynamics of the environmental controllers that operate for the development of WLs, in arid and semi-arid domains. Through the discussions presented in this text, it can be seen that there are numerous concepts that consider the scientists training, as well as the location of the WLs. Thus, it was noticed that there are environmental parameters that generate and maintain WLs in dry lands, with emphasis on Geology, Geomorphology and Hydrogeomorphology. That said, it is assumed that studies on WLs, which seek to contribute to the development of specific concepts and classifications, based on the performance of environmental controllers, are indispensable, since they collaborate with the effective management of these naturally threatened areas.
