RT Journal Article T1 Efecto de los cambios de usos del suelo sobre la recarga del acuífero Motril-Salobreña T1 Land uses changes effect over Motril-Salobreña aquifer recharge A1 Pretel, Rosa María A1 Duque, Carlos A1 Calvache Quesada, María Luisa AB Human activity over Motril-Salobreña aquifer (south of Spain) is changing traditional land uses duringthe last 50 years. In this work we aim to evaluate and quantify the main changes analyzing the aerialphotos of different years. The results show a dramatic decrease in the crops of sugarcane and elevatedincreases of the greenhouses and subtropical trees agriculture extent. Also the surface of the urban areashas been extended noticeably. The direct consequences calculated in this work are a decrease of therecharge of the aquifer by irrigation of crops near to 75 %. The velocity of these changes and the magnitudeof them point out the serious risk that involves the Motril-Salobreña aquifer resources PB Universidad de Huelva YR 2010 FD 2010 LK http://hdl.handle.net/10272/7464 UL http://hdl.handle.net/10272/7464 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 14 jul 2026
