Building resilience to water scarcity in Southern Spain: A case study of rice farming in Doñana protected wetlands

Agricultural water management needs to evolve in view of increased water scarcity, especially when farming and natural protected areas are closely linked. In the study site of Don?ana (southern Spain), water is shared by rice producers and a world heritage biodiversity ecosystem. Our aim is to contribute to defining adaptation strategies that may build resilience to increasing water scarcity and minimize water conflicts among agricultural and natural systems. The analytical framework links a participatory process with quantitative methods to prioritize the adaptation options. Bottom-up proposed adaptation measures are evaluated by a multi-criteria analysis (MCA) that includes both socioeconomic criteria and criteria of the ecosystem services affected by the adaptation options. Criteria weights are estimated by three different methods?analytic hierarchy process, Likert scale and equal weights?that are then compared. Finally, scores from an MCA are input into an optimization model used to determine the optimal land-use distribution in order to maximize utility and land-use diversification according to different scenarios of funds and water availability. While our results show a spectrum of perceptions of priorities among stakeholders, there is one overriding theme that is to define a way to restore part of the rice fields to natural wetlands. These results hold true under the current climate scenario and evenmore so under an increased water scarcity scenario.

Esta tesis doctoral se especializa en el estudio desde el interior de casas de maestros españoles proyectadas y construidas para ellos y sus familias. Casas proyectadas y construidas para ellos mismos por arquitectos “maestros” de la arquitectura española del siglo XX, que acabaron sus estudios de arquitectura después de la guerra civil y que se habían formado en la Escuela de Madrid. Las cinco casas escogidas están situadas en la provincia de Madrid, en la hoy definida como Comunidad de Madrid. Las cinco casas son para el arquitecto y su familia. También las cinco casas son de tipología unifamiliar aislada. Todas ellas tuvieron el carácter de vivienda estable, no de fin de semana, no de refugios experimentales. El método de análisis se estructura en dos grandes bloques, lo que hemos denominado “Enfocando” y “Desde dentro”. Enfocando: Se analizan las obras precedentes de similares características y se realiza un estudio de aproximación al lugar cuyo punto final es la entrada de la casa Desde dentro: Se Inicia el estudio de la vivienda en un recorrido que atiende a los parámetros de relaciones con el exterior, materiales de acabado, mobiliario, condiciones de flexibilidad y crecimiento y relaciones vivienda-estudio. Siempre con el espacio interior como protagonista del estudio Abstract The dissertation focuses on the interior space of "master`s houses" which were conceived and built for the architect and his family. The five houses selected were built in the XX Century .The five houses are located in Madrid. The five houses are detached houses, the five houses are "residences", not experimental houses, or weekend houses. The method has two parts. Focusing and Inside Focusing: This part studies previous works, with similar characteristics. Moreover this part looks at the path from the street to the main door, through the private exterior. Inside: This part studies the relationship between interior and exterior, finishing materials, furniture, flexibility and relation with the professional spaces. All these elements are studied, always with the interior space as the main character.
