Assessing the effect of alternative land uses in the provision of water resources: Evidence and policy implications from southern Europe

Ecosystem goods and services have been brought to the forefront of policy making all over the world. It is acknowledged that these goods and services underpin human well-being. The provision of water resources is amongst those services that have raised more attention, given its unquestionable value and global threats like climatic change. Nevertheless, the biophysical basis that determines the land-use/water interactions has been often ignored. For the formulation of sound decisions, it is necessary to extend the empirical basis that determines these complex relations. With this aim, the present paper analyses the effect of alternative types of land cover in the provision of water resources. In doing so, we compare hydrological, meteorological and land-cover data obtained in 15 watersheds located in the Basque Country (Northern Spain). Moreover we discuss the implications of including water resources in land-use policy and planning and address areas for further research. (C) 2011 Elsevier Ltd. All rights reserved.
