Abstract (en):
Wetlands have been recognized as very important habitats to support the ecological processes in ecosystems. They supplie goods and ecosystem services for human well-being. Many wetlands are related to groundwater and depend from of them. This explains that some actions taken in aquifers affect the function of wetlands and can threaten their existence. The UNESCO-IGCP Project 604: Wetlands Related to Groundwater in Iberoamerica, has the objective to generate knowledge about the interaction between groundwater, wetlands and human activitiess in Ibero-America and Spain, by evaluating their main hydrological characteristics, the services these ecosystems provide to humans and the factors that may induce changes in such services. In the
framework of this Project, researchers from 13 countries have provided information on the characteristics of 64 wetlands, on the aquifers linked to them, and a summary of their services. In this paper, the results obtained relative to provision of ecosystemic services have been summarized, as well as the main factors that could produce changes in them. The special reference to this type of services is due to the fact that the human socioeconomical
activities may have a greater impact on them and produce the most important changes and impacts,
especially in what refers to materials extraction, pollution, and land use.
Abstract (es):
Los humedales se han reconocido como hábitats para sostener los procesos ecológicos de los ecosistemas. Son proveedores de bienes y servicios ecosistémicos para el bienestar humano. Muchos humedales están relacionados con las aguas subterráneas y dependen parcial o totalmente de ellas. Así, algunas acciones que se realizan sobre el suelo, el territorio o los acuíferos pueden producir impactos significativos sobre los humedales, sus funciones y sus servicios, poniendo en riesgo su existencia. El proyecto UNESCO-IGCP 604: "Wetlands related to groundwater in Iberoamérica", realizado entre 2011 y 2014, tuvo como propósito generar conocimiento acerca de la interacción entre aguas subterráneas, humedales y seres humanos en Iberoamérica y España, mediante la evaluación de las características hidrológicas, los servicios que prestan estos ecosistemas y los factores que inducen cambios en dichos servicios. En el marco de este proyecto, se recopiló información en 13 países para evaluar 64 casos de estudio. Por ser uno de los ecosistemas más vulnerables ante la presión por factores de cambio inducidos por el hombre (especialmente en relación con la extracción de materiales, la contaminación y el uso del territorio), dada la relevancia de los servicios de aprovisionamiento, en este artículo se hace referencia especial a los resultados obtenidos en relación con ellos.
