Abstract

Land use changes in the Mar Menor watershed have modified the water and nutrient flows, which in turn have brought about a series of environmental changes in the lagoon and its associated wetlands. These environmental effects have been analysed by means of an integrated methodology (watershed modelling, monitoring of long-term trends in key biodiversity components and their natural values and cost-effectiveness analysis). Results show the significant economic value of the ecosystem service of nutrients removal from the Mar Menor wetlands; the increase over time of water and nutrient flows as a consequence of the increase in irrigated lands in the watershed; noticeable changes in the wetlands, particularly in their natural habitats, the steppe-bird assemblage and the wandering beetles assemblage; and a loss of natural value of the wetlands according to the EU Habitats and Birds directives. Results point to the insufficient protection of these sites and the need to apply integral sustainability policies at watershed scale. Moreover, a potential trade-off between two important environmental objectives has been identified: on the one hand to enhance the ecosystem service of nutrients removal and on the other to conserve the natural values of the Mar Menor wetlands.
