RESUMEN La presente investigación tiene como objetivo mostrar el análisis de Conglomerados (Clusters) de la población tardoantigua de Cortijo Coracho, comparando los resultados biométricos obtenidos en ella con los que se han estimado en otras poblaciones ibéricas. El estudio histórico demuestra que es poco probable la existencia de individuos visi...
This chapter proposes to study urban initiatives implemented in the framework of the EU cohesion policy as integrated urban multi-level policy mixes. The first section details the main policy level and dimensions of these policies and analytical ideas about their relationship based on policy sector and policy integration perspectives. The second se...

... Moreover, in recent years, a direct source of income has emerged: nature tourism, with tourists becoming increasingly interested in visiting active volcanoes, even in remote and underdeveloped areas. This effect has been particularly noticed on volcanic islands (e.g., [15]). Therefore, by mitigating volcanic risks, we transform the effects of volcanoes using nature-based solutions. ...
Active volcanic islands are particularly vulnerable to multi-risk natural hazards, many of which are anticipated to become more severe as a result of climate change. It is crucial to create and put into action adequate risk mitigation plans based on comprehensive long-term hazard assessments that include nature-based solutions in order to improve societal safety on these islands. Herein, we study the case of Tenerife. After a compilation and analysis of the potential resources of this island, as well as a study of its main natural hazards and how they are currently managed, we have determined that the most viable solutions are nature-based ones. Land management based on prior assessment of the island’s hazards is the key to strengthening Tenerife’s current risk mitigation plans. This will allow for a two-way relationship between the exploitation of sustainable tourism and the education of its population, both oriented toward the conservation of its geological heritage, and will promote the sustainable use of the energy and material resources currently being exploited. This contribution thus establishes the pillars from which to exploit the nature-based solutions offered by Tenerife as the only viable option for its sustainable economic development.
... The Canary Islands' governance is embedded in a complex, multilayered system comprising the Spanish national level, the Autonomous region level, two provincial governments, and an elected Island Council on each island. Tourism steers the local economy and improves local economic conditions (Antonova et al., 2021) French Guiana hosts abundant biodiversity, with seven to 10,000 plant species (De Geyer et al., 2020). Small-scale gold mining (Hammond et al., 2007) and urbanization are the two main drivers of environmental change. ...
Ecosystem services' (ES) assessments can inform sustainability policies but often translate poorly into practical decision-making due to their disconnection from local challenges. Problem framing is a crucial step in improving the operationalization of ecosystem studies. First, the study analyzes the challenges and opportunities for sustainability in three European outermost regions: the Canary Islands, French Guiana, and Reunion Island. Second, it proposes strategies to make use of ES assessments as a means to address these sustainability issues. We used a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis for strategic planning, extended with a PESTEL analysis, standing for Political, Economic, Socio-cultural, Technological, Environmental , Legal, and Regulatory. Semi-structured interviews (n = 38) were conducted to identify PESTEL factors facilitating or impeding sustainability in the case studies. Interviews were coded into PESTEL factors before being synthesized and reported into SWOT matrices. We suggest seven ESs implementation strategies addressing these challenges from these SWOT matrices. Finally, this paper highlights the potential contributions of ES-based strategies to achieving multiple United
... One of the most outstanding examples of the necessity for efficient water resources management is the Canary Island archipelago (Spain) (Custodio et al., 2016;Custodio et al., 2015), which holds 2.2 million inhabitants and received more than 15 million tourist visitors in 2019 (Hernández-Martín et al., 2021). The strong urban development of the Canary Islands and the waterproofing of its land surface is leading buildings and urbanization resorts to the installation of stormwater infiltration facilities in the last decade. ...
The increase in the frequency of extreme precipitation events due to climate change, together with the continuous development of cities and surface sealing that hinder water infiltration into the subsoil, is accelerating the search for new facilities to manage stormwater. The Canary Islands (Spain) are taking advantage of the knowledge acquired in the construction of water mines to exploit a novel stormwater management facility, which we have defined as a dry gallery. Dry galleries are constituted by a vertical well connected to a horizontal gallery dug into highly permeable volcanic layers of the vadose zone, from where infiltration takes place. However, the lack of scientific knowledge about these facilities prevents them from being properly dimensioned and managed. In this work, we simulate for the first time the infiltration process and the wetting front propagation from dry galleries based on a 3D unsaturated flow model and provide some recommendations for the installation and sizing of these facilities. The fastest advance of the wetting front takes place during the earliest times of infiltration (<2 h), with plausible propagation velocities and infiltration rates higher than 1000 m∙d⁻¹ and 2 m³∙s⁻¹. As time progresses, the propagation velocity and infiltration rate decrease as a consequence of the hydraulic gradient attenuation between the gallery and the aquifer. Therefore, stormwater infiltration is a highly transient process in which a sizing underestimation of 100% may be committed if unsaturated conditions or geological configuration are neglected.
