GIS Assessment of Mass Tourism Anthropization in Sensitive Coastal Environments: Application to a Case Study in the Mar Menor Area

Abstract

On the Mediterranean coast, the tourism activity which has developed since the 1950s has become a mass tourism industry in recent decades, cohabitating with natural spaces of high environmental value. These sensitive areas are thus subjected to a varied catalog of anthropizing actions (urbanization of the natural soil, modification of the dune balances by the construction of port infrastructures, alteration of marine ecosystems by recreational activities, etc.). All these interrelated elements are often difficult to analyze in a comprehensive way because of their diffuse nature. This paper proposes a methodology based on GIS analysis for the evaluation of diffuse anthropization associated to tourism in sensitive coastal environments. By using different indicators of territorial transformation, a complete method is proposed to establish the index of diffuse anthropization of a territory. This methodology, which is easily applicable in a generalized manner in different cases for developed countries, will be applied in the Mar Menor, a coastal lagoon area in the Mediterranean that has been suffering from mass tourism during recent decades. The results will show the important impact of several actions linked to tourism and the worrying inertia that the current trend can cause in the lagoon's ecosystem.

Urban Transformations as an Indicator of Unsustainability in the P2P Mass Tourism Phenomenon: The Airbnb Case in Spain through Three Case Studies

“…The democratization of access to tourism has popularized mass tourism on the beaches of the Mediterranean in Europe since the 60s [4,5]. This phenomenon has, on many occasions, shown important signs of unsustainability in its behaviour in the last decades [6]. In this sense, the concept of sustainability in relation to the consumption of resources and the generation of intrinsically unbalanced models has been widely debated for mass tourism [7].…”

“…It shows which neighbourhoods have the highest rate of growth in prices, comparing the average rate of each neighbourhood in one period with the maximum rate found in the neighbourhood with the highest growth for that period. In order to carry out a comparative analysis between cities, the value of this rate has been adimensionalized for each neighbourhood, so that it is purely a percentage indicator (6).…”

Predictive Diagnosis of Agricultural Periurban Areas Based on Territorial Indicators: Comparative Landscape Trends of the So-Called “Orchard of Europe”

“…In this field, the retrospective analysis of mature case studies of these territories in a developed country in America [7] or Europe [8] for example can prove very helpful as a learning element for the development of today's emerging countries. Phenomena such as the accelerated growth of large cities [9,10], rural-urban migrations [11] or the impact of mass tourism [12] are common examples of causes linked to the anthropization, or loss of identity of these territories. Such territories have traditionally been one of the basic livelihoods of cities.…”

New Strategies to Improve Co-Management in Enclosed Coastal Seas and Wetlands Subjected to Complex Environments: Socio-Economic Analysis Applied to an International Recovery Success Case Study after an Environmental Crisis

“…In this context, the use of a socio-ecological framework implementing economical approaches and GIS methodologies for the diagnosing and managing complex natural areas exposed to the intense process of diffuse or specific anthropization can prove very interesting [2,49,50]. The breakthrough developed by GIS tools in recent years can bring new high value approaches to the existing integrated management strategies in the field of diagnostics [14,51], participation of stakeholders, and implementation of measures for the recovery of these areas facing environmental crises. This article presents a comprehensive socio-ecological framework implemented with GIS and cost value methodologies for the Mar Menor lagoon in Spain and its latest results, which have become a case of some success in 2018 in the aftermath of an environmental crisis of the international relevance in 2015.…”
