Climate change and its impacts in the Balearic Islands: a guide for policy design in Mediterranean regions

Abstract

Understanding the local effects of global warming-derived impacts is important to island systems due to their fragile environmental conditions. This is especially true when it comes to Mediterranean insular regions as they are climate change (CC) hotspots where adaptation and mitigation policy design is an urgent matter. Looking at 2030 as a time horizon for climate action and focusing on the Balearic Islands, this paper reviews the physical changes projected for the coming decades as a result of CC and analyses their impacts on regional environmental, economic and social variables. Mitigation and adaptation measures are also proposed based on the identified priority impacts. The fact the Balearics are a top world holiday destination allows the analysis to serve as a guide to other Mediterranean islands with tourism-based economies facing similar CC scenarios. Results show the projected rise of temperature and sea level; the reduction of the average precipitation and increase in evapotranspiration, the droughts and the increase in ocean acidification and deoxygenation are the main threats faced by the Balearics, this putting their economy at risk due to the high tourism’s vulnerability to CC. Mitigation and adaptation action on terrestrial and marine ecosystems, water resources, energy, infrastructure and urban planning, human health, economy, law and education is recommended. Sustainable mobility and waste managing are also viewed as important fields for mitigation action. Conclusions show that diversifying the current socioeconomic model is needed to increase the community and territory resilience.

The Economic Value of Coastal Amenities: Evidence from Beach Capitalization Effects in Peer-to-Peer Markets

“…2019 ). Similar concerns are presented in Enríquez et al ( 2017 ) and Torres et al ( 2021 ). Experts warn that the current uncontrolled touristification of environmental resources is likely to accelerate erosion and the loss of beach width, which will paradoxically result in a loss of tourism attractiveness for the islands.…”

Maritime transport disruption risk for EU islands under a changing climate

“…Various climate change stressors can affect both harbour infrastructure and ships en route. For example, ports are strongly impacted by rising sea levels, affecting port facilities and increasing the risk of ooding (e.g., Torres et al, 2021). Global mean sea-level rise has accelerated in the last century and will likely rise by 0.43 to 0.84 m until 2100, depending on the emission scenario (Pörtner et al, 2019).…”

A comprehensive review of battery thermal management systems for electric vehicles

“…In addition, global warming and climate change are showing their effects more and more every day, and it is an undoubted fact that the use of fossil fuels is largely responsible for this situation. [1][2][3][4][5][6][7][8] In order to prevent the worst scenarios that will occur as a result of this, the carbon released into the atmosphere had to be brought under control with certain control mechanisms all over the world. In this context, the first step was taken with the United Nations Framework Convention on Climate Change; this agreement was expanded with the Kyoto Protocol and took its final form with the Paris Climate Agreement.…”
