Most of adaptation measures to climate change implemented in the Spanish Mediterranean coast consist of a set of actions or specific measures that, although framed in initiatives such as the Adaptation Strategy to Climate Change in the Spanish Coast, have been designed individually. Moreover, in many cases, its long-term effectiveness has not been tested. Within this context, there is a need to develop adaptation strategies for the coastal zone based on the concept of adaptive planning in which different adaptation measures are combined to achieve a set objectives under a given climatic scenario. Such strategies are very dependent on the physical, socio-economic and dynamic characteristics of the coastal zone of interest. Consequently, it is important to progress in their development for different types of coast. In this context, the general objective of this subproject is to (i) analyse the adaptability to the Climate Change of the Spanish Mediterranean coast, (ii) propose a response strategy based on the design of specific adaptation pathways for management units representative of the Mediterranean coast that can be adapted locally and, (iii) contribute to the evaluation of the adaptability integrating coastal processes with the extreme hydrometeorological risks of terrestrial origin as flash floods. To this end, the adaptation measures most appropriate to the characteristics of the Mediterranean coast will be identified and defined in terms of technical, economic, financial, environmental and social limits that will be used to define the adaptation tipping points. Likewise, adaptation measures implemented to date in the Spanish Mediterranean coast will be analysed and evaluated through a multidimensional analysis that includes aspects related to its sustainability and effectiveness. Among the different aspects, the social acceptability of the key stakeholders will be analysed to determine their role in the development and implementation of adaptation strategies. At the same time, a methodology to classify the coastal zone into homogeneous management units to define and prioritize adaptation measures will be developed and applied in the Spanish Mediterranean. From this analysis, specific adaptation pathways will be proposed for selected case studies representing the Spanish Mediterranean coastal zone. For each one, their adaptation tipping points, the sequence of actions and their temporal dependence will be identified to adapt to given climate change scenarios. Finally, obtained results will be generalised in the form of generic adaptation pathways for the most representative areas of the Mediterranean coast. In addition to analysing the "maritime" dimension in the different aspects mentioned, an overall objective of this subproject is to integrate obtained results in all the phases of the study with the analysis of the "terrestrial" component (UB subproject) to contribute to perform an integrated adaptability analysis in the coastal zone taking into account both risk factors.
