Impact of environmental change un surface water resources in the Douro basin

In recent decades, the environmental changes due to human development have put pressure on water resources in the Mediterranean basin, a region where availability of water has been historically limited. In this work we analyze the evolution and variability (1961-2005) of streamflows in one of the la...

description In recent decades, the environmental changes due to human development have put pressure on water resources in the Mediterranean basin, a region where availability of water has been historically limited. In this work we analyze the evolution and variability (1961-2005) of streamflows in one of the largest rivers basin of the Iberian Peninsula, the Duero River basin. Moreover, the factors responsible for such evolution are assessed. Results show a significant and generalized decrease of water resources in the basin, together with changes in the timing of monthly distribution. Climate itself, with quasi-stationary precipitation and increasing temperatures in the long-term, is not enough to explain the decreasing streamflows. Thus, observed land-cover expansion in the headwaters is thought to be increasingly contributing to the hydrological depletion. On the other hand, impoundment of water through dams is increasing in the basin and consequently contributing the hydrological change. Results offer the basis for future projections of water availability in scenarios of water scarcity due to forthcoming climate change La disponibilidad de recursos hídricos ha sido históricamente un factor limitante de desarrollo en los países de la cuenca mediterránea. Durante las últimas décadas la presión sobre la disponibilidad se ha acentuado debido a los cambios ambientales observados como resultado del desarrollo industrial. En este trabajo se analizan la evolución y variabilidad recientes (1961-2005) de los recursos hídricos superficiales –el caudal en los ríos– en una de las cuencas hidrográficas de mayor entidad de la Península Ibérica, y los factores ambientales responsables de su evolución. Los resultados del trabajo muestran un descenso notable y generalizado en los caudales en la región, acompañado de un cambio en los regímenes fluviales. La evolución del clima, con unas precipitaciones muy variables pero sin tendencias notables a largo plazo, y unas temperaturas en aumento, explica en parte, pero no en su totalidad, el descenso hidrológico. En las cabeceras fluviales se ha detectado un incremento significativo de la cubierta vegetal durante el periodo de estudio, el cual parece estar participando en gran medida en el descenso de caudales. Por otro lado, la regulación por medio de embalses está incrementando en la cuenca y con ello contribuyendo al cambio hidrológico en la región. Los resultados obtenidos ofrecen la base conceptual para proyectar la disponibilidad futura de los recursos hídricos en los escenarios de mayor escasez como consecuencia del cambio climático venidero.

In this work we analyze the evolution and variability (1961-2005) of streamflows in one of the largest rivers basin of the Iberian Peninsula, the Duero River basin. Moreover, the factors responsible for such evolution are assessed. Results show a significant and generalized decrease of water resources in the basin, together with changes in the timing of monthly distribution. Climate itself, with quasi-stationary precipitation and increasing temperatures in the long-term, is not enough to explain the decreasing streamflows. Thus, observed land-cover expansion in the headwaters is thought to be increasingly contributing to the hydrological depletion. On the other hand, impoundment of water through dams is increasing in the basin and consequently contributing the hydrological change. Results offer the basis for future projections of water availability in scenarios of water scarcity due to forthcoming climate change La disponibilidad de recursos hídricos ha sido históricamente un factor limitante de desarrollo en los países de la cuenca mediterránea. Durante las últimas décadas la presión sobre la disponibilidad se ha acentuado debido a los cambios ambientales observados como resultado del desarrollo industrial. En este trabajo se analizan la evolución y variabilidad recientes (1961-2005) de los recursos hídricos superficiales –el caudal en los ríos– en una de las cuencas hidrográficas de mayor entidad de la Península Ibérica, y los factores ambientales responsables de su evolución. Los resultados del trabajo muestran un descenso notable y generalizado en los caudales en la región, acompañado de un cambio en los regímenes fluviales. La evolución del clima, con unas precipitaciones muy variables pero sin tendencias notables a largo plazo, y unas temperaturas en aumento, explica en parte, pero no en su totalidad, el descenso hidrológico. En las cabeceras fluviales se ha detectado un incremento significativo de la cubierta vegetal durante el periodo de estudio, el cual parece estar participando en gran medida en el descenso de caudales. Por otro lado, la regulación por medio de embalses está incrementando en la cuenca y con ello contribuyendo al cambio hidrológico en la región. Los resultados obtenidos ofrecen la base conceptual para proyectar la disponibilidad futura de los recursos hídricos en los escenarios de mayor escasez como consecuencia del cambio climático venidero.
