Background: Climate change has been shown to be directly linked to multiple physiological sequelae and to impact health consequences. However, the impact of climate change on mental health globally, particularly among vulnerable populations, is less well understood. Objective: To explore the mental health impacts of climate change in vulnerable populations globally. Methods: We performed an integrative literature review to identify published articles that addressed the research question: What are the mental health impacts of climate change among vulnerable populations globally? The Vulnerable Populations Conceptual Model served as a theoretical model during the review process and data synthesis. Findings/Results: One hundred and four articles were selected for inclusion in this review after a comprehensive review of 1828 manuscripts. Articles were diverse in scope and populations addressed. Land-vulnerable persons (either due to occupation or geographic location), Indigenous persons, children, older adults, and climate migrants were among the vulnerable populations whose mental health was most impacted by climate change. The most prevalent mental health responses to climate change included solastalgia, suicidality, depression, anxiety/eco-anxiety, PTSD, substance use, insomnia, and behavioral disturbance. Conclusions: Mental health professionals including physicians, nurses, physician assistants and other healthcare providers have the opportunity to mitigate the mental health impacts of climate change among vulnerable populations through assessment, preventative education and care. An inclusive and trauma-informed response to climate-related disasters, use of validated measures of mental health, and a long-term therapeutic relationship that extends beyond the immediate consequences of climate change-related events are approaches to successful mental health care in a climate-changing world.

Historical exploitation of the Mediterranean Sea and the absence of rigorous baselines makes it difficult to evaluate the current health of the marine ecosystems and the efficacy of conservation actions at the ecosystem level. Here we establish the first current baseline and gradient of ecosystem structure of nearshore rocky reefs at the Mediterranean scale. We conducted underwater surveys in 14 marine protected areas and 18 open access sites across the Mediterranean, and across a 31-fold range of fish biomass (from 3.8 to 118 g m(-2)). Our data showed remarkable variation in the structure of rocky reef ecosystems. Multivariate analysis showed three alternative community states: (1) large fish biomass and reefs dominated by non-canopy algae, (2) lower fish biomass but abundant native algal canopies and suspension feeders, and (3) low fish biomass and extensive barrens, with areas covered by turf algae. Our results suggest that the healthiest shallow rocky reef ecosystems in the Mediterranean have both large fish and algal biomass. Protection level and primary production were the only variables significantly correlated to community biomass structure. Fish biomass was significantly larger in well-enforced no-take marine reserves, but there were no significant differences between multi-use marine protected areas (which allow some fishing) and open access areas at the regional scale. The gradients reported here represent a trajectory of degradation that can be used to assess the health of any similar habitat in the Mediterranean, and to evaluate the efficacy of marine protected areas.

A transition from fossil to renewable energy requires the development of sustainable electric energy storage systems capable to accommodate an increasing amount of energy, at larger power and for a longer time. Flow batteries are seen as one promising technology to face this challenge. As different innovations in this field of technology are still under development, reproducible, comparable and verifiable life cycle assessment studies are crucial to providing clear evidence on the sustainability of different flow battery systems. Based on a review of 20 relevant life cycle assessment studies for different flow battery systems, published between 1999 and 2021, this contribution explored relevant methodological choices regarding the sequence of phases defined in the ISO 14,040 series: goal and scope definition, inventory analysis, impact assessment and interpretation. Inspired by good practice examples, common gaps and weaknesses were identified and recommendations for comparative life cycle assessment studies were derived. This includes suggestions for an expanded functional unit definition, a provision of more detailed and transparent reporting of LCI data while using input/output tables. Outcomes of this study are also of relevance for the amendment of the Batteries Directive 2006/66/EC, where first drafts are under revision in the European Council, including the introduction of a battery passport, which should encourage battery producers to reduce their carbon footprint and avoid problematic materials.

AbstractThe planetary boundary framework constitutes an opportunity for decision makers to define climate policy through the lens of adaptive governance. Here, we use the DICE model to analyze the set of adaptive climate policies that comply with the two planetary boundaries related to climate change: (1) staying below a CO2 concentration of 550 ppm until 2100 and (2) returning to 350 ppm in 2100. Our results enable decision makers to assess the following milestones: (1) a minimum of 33% reduction of CO2 emissions by 2055 in order to stay below 550 ppm by 2100 (this milestone goes up to 46% in the case of delayed policies); and (2) carbon neutrality and the effective implementation of innovative geoengineering technologies (10% negative emissions) before 2060 in order to return to 350 ppm in 2100, under the assumption of getting out of the baseline scenario without delay. Finally, we emphasize the need to use adaptive path-based approach instead of single point target for climate policy design.

El presente artículo surge de la necesidad de desvelar la influencia del desarrollo turístico en las dimensiones del desarrollo sostenible de la comunidad de Caibarién (Cuba). La información se obtuvo mediante revisión documental y entrevistas semi estructuradas. Los fundamentos teóricos y metodológicos que soportan el tratamiento de este trabajo se estructuran a partir de la producción científica relativa a los temas del desarrollo turístico y el turismo sostenible. Los principales resultados mostraron que la estrategia de desarrollo de Gaviota S.A en los Cayos de Villa Clara, influye indirectamente en la sostenibilidad de la comunidad de Caibarién, lo cual coincide con lo que plantea la literatura académica y presenta su pertinencia también para el caso de Cuba, cuya organización socioeconómica y política se distancia del paradigma neoliberal global. Si bien existen algunas pautas que muestran una tendencia hacia el desarrollo sostenible, aún se identifican aspectos negativos en el modelo de desarrollo turístico que habrán de ser considerados tanto en futuras investigaciones como en sus implicaciones prácticas en la industria turística de Cuba y de otras latitudes. This article arises from the need to reveal the influence of tourism development on the dimensions of sustainable development in the community of Caibarién, Cuba. The information was obtained through documentary review and semi-structured interviews. The theoretical and methodological foundations that support the treatment of the subject are structured from the scientific production related to the topics of tourism development and sustainable tourism. The main results showed that the development strategy of Gaviota SA in the Villa Clara Keys, indirectly influences the sustainability of the Caibarién community, which coincides with what is stated in the academic literature and is also relevant for the case of Cuba, whose socio-economic and political organization distances itself from the global neoliberal paradigm. Although there are elements that show a trend towards sustainable development, negative aspects were still identified as a consequence of the presence of tourism development that will have to be considered both in future research and in its practical implications in the tourism industry of the Island and of other latitudes.

Conducted by the ESPACE French laboratory with the Ressource research consultancy and the Tour du Valat, the CAMPLAN research program on the integrated management of the Camargue and Plan-du-Bourg hydro-system, is based on the observation made by several managers of natural areas of this territory: an increasing inability of the water governance to maintain the adaptive capacity of the hydraulic system faced with global change, and most particularly with sea level rise. In this research program, our goal was to combine the knowledge produced by the multidisciplinary research team in order to identify the elements which, in the functioning of the territorial system, are favourable and unfavourable to its adaptation. The complexity and the breadth of the gathered knowledge have required a systemic approach. The analysis of the structure of the constitutive relationships of the Camargue system brought to light two ways to adapt, from which the levers and brakes to the adaptability of the Camargue area were examined.
