“…In that period, there was a progressive transfer from agricultural use to other uses [5]. The great urbanisation process [9] and new irrigation agriculture needed water resources [10]. The wood from trees was not so important in the new forms of production [8], [11].…”

Despite being a relatively stable sea compared to the great oceans, the Mediterranean is not a risk-free place of changes in the coast, both anthropogenic and natural. The coast is home to a large part of the population and cities which are generally in constant growth due to the quality of life and the possibilities offered (i.e. tourism and other activities linked to the sea). In Mediterranean coastal cities, the first maritime line is usually the one with the highest economical value and, where the space is used intensively. For this reason, land managers have developed strategies to occupy the maximum extension of the coast. Some of these are new uses for old port areas, take advantage of coastal containment works, extending the beaches mean artificial regenerations, the construction of breakwaters and, adding waste materials in order to increment the land, gain it to the sea. So that, the urban coastal lines of Mediterranean cities have been changing a long time. This work presents these changes in the past years (last 60 years) through a methodology based on the comparison of aerial photography from different times (1956-1957 and PNOA 2014-2016) in the following settlements of the SouthEast of Spain:

“…These important land transformations have been recorded in Spain since the 1990s and have affected the urban environment in particular, and as aforementioned, this has intensified on the Mediterranean coast [3]. According to Greenpeace [24], in the Valencian region the artificial surface area practically doubled between 1987 and 2005, from 15,000 to almost 30,000 hectares, with an increase in the number of houses built between 1996 and 2006 going from 30,000 to 92,000 [25]. A clear example of this can be observed in the province of Alicante, which, between 1997 and 2008, was the third Spanish province in terms of the number of houses built [26].…”

Adaptation Strategies of the Hydrosocial Cycles in the Mediterranean Region

The Spanish Mediterranean region has been affected by several factors over the years (climatic conditions of aridity, high water demands, rapid and intense urban and population growth, climate change), that have generated a negative water balance whereby water resources are unable to meet the demand. Diversifying supply sources by resorting to new resources has been a necessity that has stimulated the expansion and integration of non-conventional water sources (desalination and reuse of reclaimed water) and sustainable solutions. The aim of this paper is to evaluate the adaptation strategies that have been developed in Alicante, Benidorm and Torrevieja in order to adjust their hydrosocial cycles to development and future scenarios. The theoretical analysis developed in this paper is corroborated by the study of the hydrosocial cycle evolution of three cities in the southeast of Spain, and the adaptive measures that the different stakeholders involved in the cycle have developed in each of them. The input and output of the systems are accounted for with information provided by the management companies in each of the phases (urban consumption; treated, reused and desalinated volumes), which highlight how the diversification of resources and the incorporation of non-conventional resources have been essential for adaptation.Southeast Queensland (Australia) where rainwater is collected [9], and the city of Tucson (AZ, USA) where groundwater, surface water, reclaimed water and grey water are combined [10,11].Water scarcity is clearly manifested in the Spanish Mediterranean coast, the Balearic Islands and the Canary Islands, and various measures have been carried out in order to mitigate it [1]. Given the physical-ecological characteristics of Spain, over the centuries a large amount of infrastructure has been built to try and store water. An example is the large number of dams and reservoirs, about 1200, which are distributed throughout Spain [12], with a storage capacity of about 56,000 hm 3 [13]. Among other functions, these structures have helped regulate and supply water to the cities. However, in some regions the creation of reservoirs has not been enough, because their rivers do not have the necessary flows to cover the demand of the area. Channels between ceding basins and deficit basins have been built, for example, the Tajo-Segura transfer. This channel connects the Tajo basin, located in the centre of the peninsula, with the Segura basin, in the southeast of Spain [14]. Due to this transfer, the regions that make up the Segura basin, an area characterized by its structural water shortage and reduced rainfall, have been able to supply water for urban demand and agricultural demand (which require around 80% of the total demand of the basin). These water regulation and transport systems have been the basis of the Spanish model for decades. However, in some regions, such as those located on the Mediterranean coast, in the late 1990s the combination and mixing of surface water (own and external) and groundwater wa...

This contribution attempts to examine first how different theoretical and methodological perspectives from Geography and environmental sciences explore water flows and their physical and social dimensions in the city, as well as their changes in response to the emerging urban complexities and challenges. Using in particular the framework provided by Urban Political Ecology, I look at how the physical and social dimensions of water flows unfold and influence the urbanization process and, in turn, are influenced by urbanization. In the second part, attention is paid to urban coastal areas of the Mediterranean as candidate laboratories of analysis under urban political ecology since they are subject to rapid processes of social environmental change in which water plays a fundamental part. Case studies included to examine physical and social dimensions of water flows include heritage towns (Venice) and mass tourism resorts (Benidorm).
