ABSTRACT El estudio de las coberturas y usos del suelo y su variación a lo largo del tiempo obedece a gran cantidad de fines: estudios medioambientales, económicos, sociales, planificación territorial (infraestructuras, urbanismo o agrícola), estratégicos, etc., como fuente de información y de diagnóstico geográfico, asimismo constituye un elemento clave en la toma de decisiones. El análisis de la evolución de las coberturas y usos del suelo en el tiempo desde una perspectiva multidisciplinar en la Marina Baixa permite la evaluación de las políticas llevadas a cabo y la anticipación para la adecuada orientación de actuaciones futuras. En este sentido, se considera conveniente poner a punto una metodología de entrada y tratamiento de los datos espaciales, basada en la utilización de Sistemas de Información Geográfica (S.I.G.) y fotografía aérea. El presente trabajo trata de mostrar y cuantificar la cronosecuencia de las coberturas y usos de suelo de la comarca de la Marina Baixa, como resultado de la tarea de fotointerpretación y cartografiado, sin atender a las causas que la motivan o las consecuencias que implican. Próximos estudios dentro del mismo proyecto incurrirán en los efectos sobre la biodiversidad vegetal y los balances hídricos para el periodo estudiado. The study of variations through time in land cover and land use as sources of information and geographical diagnosis, is due to many different factors: environmental, economical, social territorial planning (infrastructure, urban or farming planning), strategic research etc., and thus is a key element for decision makers. The analysis of the evolution of land cover and land use through time from a multidisciplinary point of view in the Marina Baixa allows for the evaluation of implemented policy as well as the anticipation of future planning policies. To this effect, we have developed a methodology of spatial data input and management, based on the use of Geographical Information Systems (G.I.S.) and aerial photographs. The present work attempts to demonstrate and quantify land cover and land use chronosequence of the Marina Baixa region, using photo-interpretation and cartographic work, without assessing the causes that motivate land use changes or their consequences. Forthcoming studies within the same project will include in the effects of vegetal biodiversity and hydrological balances over the study period.

    ABSTRACT: The aim of this chapter is to examine the processes of change in land cover and land use over the last 44 years, at regional scale, in a traditional, rural south-eastern Spanish catchment. Land use has changed dramatically over recent decades throughout the Mediterranean. Much of this change has been driven by shifts in agricultural and socioeconomic policy. Analysis of aerial photography for the Marina Baixa catchment has revealed a significant decline in traditional agriculture and conversion to forestry or intensive croplands. The consequences of economic globalisation are reflected here in a shift from traditional to intensive agriculture and in human migration from rural to urban areas, as well as in the development of tourism. Land-use changes are correlated with socioeconomic structural forces in order to demonstrate how these changes affect the basic resources of the area and to provide a clearer understanding of possible future trends.

    ABSTRACT: We analyzed the effects of changes in land cover on the water balance in Spain's Marina Baixa County, on the Mediterranean coast. To reveal how different land management strategies have affected the area's environment, four municipalities within the same catchment were studied: Benidorm, Callosa d'en Sarrià, Beniardà, and Guadalest. In the municipalities of Callosa and Benidorm, the proportion of the area covered by woodland declined by 4.2% and 30.2%, respectively, and woodland was replaced by agriculture and urban development. The abandonment of farmland produced a 17% increase in the proportion of the area covered by vegetation in Guadalest and Beniardá, where frequent forest fires have exacerbated a decrease in the area of pine woodland. Tourism development in Benidorm has been accompanied by an increase in the transportation infrastructure and by an expansion of areas with an impermeable surface, with the lowest level of infiltration into the aquifer system. These changes have generated a net water deficit in Callosa and Benidorm of more than 6 Mm(3)/year, creating a high demand for water imported from other municipalities (Guadalest and Beniardá) or from outside of the county to maintain the sustainability of the current water management strategies. The Marina Baixa case study is representative of many of the world's coastal areas that are undergoing rapid urban development based on an inappropriate understanding of human progress based mainly on economic development and thus provides insights into water management in other areas.

    ABSTRACT: In the Marina Baja region there is a tradition of fierce competition for water resources which necessitates the regulation of institutions in order to satisfy the interests of the different water users. The management of the water resources in this region is based on the water exchange between the different users with no legal modification of the water concessions. This situation requires continuous negotiation in order to maintain the balance between urban, tourism and the agricultural demand. In this article we define, describe and analyse the equilibrium model for water resources of the Marina Baja District using a simultaneous equations model (SEM). We analyse variables that influence the water management model through a simultaneous relationship between the above-mentioned demands in the region of the Marina Baja, using a methodology that directly links urban and irrigation demands and makes them relevant to one another from a socioeconomic point of view.
