Anàlisi del metabolisme ambiental de nuclis turístics litorals : el cas de Menorca

L'objectiu del present estudi és l'anàlisi del metabolisme energètic associat a nuclis turístics litorals de l'illa de Menorca (Mediterrani occidental) i el grau d'autosuficiència a partir d'energies renovables. La caracterització dels nuclis i la definició del perfil del turista s'ha realitzat mitjançant SIG i informació de qualitat a partir d'enquestes. Els principals resultats mostren que els nuclis turístics de Menorca tenen unes emissions associades entre 213 i 318 kg de CO2 per estada. De mitjana, el recorregut del turista fins a la illa (mobilitat externa) és de 1334 km (representant el 80% de les emissions), mentre que la mobilitat interna durant l'estada és de 22 km. A diari, cada turista consumeix entre 8 i 26 kWh d'electricitat, consum que es podria satisfer en un 100% amb la instal·lació de sistemes fotovoltaics a les cobertes del nucli.El objetivo del presente estudio es el análisis del metabolismo energético asociado a los núcleos turísticos litorales de la isla de Menorca (Mediterráneo occidental) y el grado de autosuficiencia a partir de energías renovables.

The characterization of the nuclei and the definition of tourism profile has been created using GIS and quality information from the interviews. The main results show that the tourism nuclei of Minorca have associated emissions between 213 and 318 kg of CO2 on stay. On average, the tourism route to arrive on the island ( external mobility) is 1334 km ( theese represents the 80% of the emissions), while the internal mobility during the stay is 22km. Every day, each tourist consumes between 8 and 26 kWh of electricity, that consum could be satisfied in a 100% with the installation of photovoltaic systems on the roofs of the nuclei.Lo scopo del presente articolo è l'analisi del metabolismo energetico nei nuclei turistici costieri dell'isola di Minorca (Mediterraneo occidentale) e il grado d'autosufficienza energetica basata sulle energie rinnovabili. La caratterizzazione dei nuclei e la definizione del profilo del turista si è sviluppato con l'utilizzo del GIS e attraverso informazioni di qualità ricavate dalle interviste. I principali risultati mostrano che nei nuclei turistici di Minorca ogni turista ha delle emissioni associate di 213 e 318 kg di CO2 per ogni periodo di soggiorno. In media, il percorso del tursita fino all'isola (mobilità esterna) è di 1334 km (rappresentando l'80% delle emissioni totali), mentre la mobilità interna durante il periodo di soggiorno è di 22 km. Quotidianamente, ogni turista consuma fra 8 e 26 kWh d'elletricità; tale quantità energètica potrebbe essere soddisfata al 100% dall'installazione d'impianti fotovoltaici sui tetti del nucleo

Environmental and self-sufficiency assessment of the energy metabolism of tourist hubs on Mediterranean Islands : the case of Menorca (Spain)

SostenipraEnergy performance of island tourism has been analyzed in the literature. However, tourist services tend to concentrate in tourist hubs, especially where mass tourism predominates (e.g., Mediterranean), and the energy metabolism of these systems has not yet been assessed. The present paper models and estimates the energy metabolism of tourist hubs in the Menorca Island (Spain) by integrating social, geographical and environmental methods. Mobility (both external and internal) and consumption of lodging services were characterized through surveys to users (tourists) and business managers. An environmental assessment evaluated CO₂ emissions, and energy self-sufficiency potential was estimated via GIS data. The results indicate that, on average, a tourist consumes 4756 MJ with associated emissions of 277 kg of CO₂ per stay (20 days on average). Of all the energy flows, external mobility contributes the most to total emissions (77%). For every day spent in a tourist hub, a tourist consumes between 29 MJ and 93 MJ in lodging services, consumption that could be 100% satisfied by photovoltaic systems, and these systems would result in positive effects for the island. Sustainable tourism management might focus on promoting environmentally friendly transportation, energy efficient practices, and environmental communication through ecolabeling
