While every society can be exposed to heatwaves, some people suffer far less harm and recover more quickly than others from their occurrence. Here we project indicators of global heatwave risk associated with global warming of 1.5 and 2 °C, specified by the Paris agreement, for two future pathways of societal development representing low and high vulnerability conditions. Results suggest that at the 1.5 °C warming level, heatwave exposure in 2075 estimated for the population living in low development countries is expected to be greater than exposure at the warming level of 2 °C for the population living in very high development countries. A similar result holds for an illustrative heatwave risk index. However, the projected difference in heatwave exposure and the illustrative risk index for the low and very high development countries will be significantly reduced if global warming is stabilized below 1.5 °C, and in the presence of rapid social development. Climate extremes, exposure and vulnerability all contribute to global difference in heatwave risk. Here the authors investigated the inequality in global heatwave risk under both 1.5 and 2 °C scenarios and found that heatwave risk for the poor under 1.5 °C scenario exceeds that risk for the rich under 2 °C scenario.

Although studies have explored how loneliness varies between rural and urban areas during the COVID-19 pandemic, the results have been inconsistent, and most studies are observational. Therefore, it remains unclear how urban–rural differences affected loneliness in a pandemic. Our study uses nationwide data to clarify this, covering periods before and during the pandemic. We analyze a longitudinal dataset from Hiroshima University’s Household Behavior and Finance Survey, which collected demographic, socioeconomic, and psychological characteristics of Japanese adults in 2020, 2021, and 2022, thus reflecting the COVID-19 pandemic timeline. The results show that approximately 50% of those surveyed experienced long-term loneliness, while about 6.5% developed loneliness during the pandemic. Although our weighted logit regression models showed few differences in loneliness during the pandemic between urban and rural areas, socioeconomic changes, such as beginning to live alone, leaving full-time employment, and decreased financial satisfaction, were identified as high-risk factors for loneliness, and their impact varied between rural and urban areas. Our results reflect that rural–urban differences have an effect on people’s loneliness during a pandemic but need to be considered together with socioeconomic changes. This knowledge can aid governments and healthcare providers in identifying those most at risk of loneliness within urban–rural regional boundaries.

Flood risk in urban areas around the world is increasing due to socio-economic development and climate change. Urban climate adaptation measures are beneficial over the longer term, particularly in coastal areas, yet the upfront costs of such measures are significant. Moreover, public actors responsible for adaptation to flood risk face constrained budgets. A promising strategy for overcoming these constraints and enabling greater adaptation investment is land reclamation that includes adaptation, i.e. flood risk reduction. Land reclamation in high-value urban areas can generate substantial revenues through the sale or lease of new land, or taxes on increased economic activities, thus offsetting public adaptation investments. This paper explores the potential of land reclamation for leveraging public adaptation investments and associated distributional issues, by analysing 3 urban land reclamation and adaptation projects in Germany, the Netherlands and the Maldives. We find that all projects have leveraging potential, and leveraging in projects primarily aimed at land creation is particularly high. Further, due to low adaptation costs needed to protect revenue streams in such projects, these investments appear to be ‘low-regret’. Regarding distributional aspects, high project costs and limited public budgets for adaptation constrain public actors’ ability to ensure equitable outcomes through planning instruments, for example, social housing. Further, in implementation, competition for project benefits can lead to further inequalities. We conclude that urban land reclamation presents a significant opportunity to leverage public adaptation investments under certain conditions. We further outline future research needs including to extend land-based financing theory from related urban infrastructure sectors to inform the design of equitable governance arrangements and to better understand the role of such urban land reclamation projects in regional or national development pathways.

In trying to shape an “authentic” rural Maramureş, tourist guesthouse owners promote local hospitality as a brand. Mechanisms of branding hospitality, as part of a tourism marketing strategy mean re-enacting their “social memory” related to Romanian peasants’ sociocultural universe. The use of rural guesthouses as arenas for staging peasant identity for tourists entails the presentation of a peasant “essence” as reflected in physical traces (replications of peasant domestic universe) associated with traditional practices and knowledge relating to natural and agricultural landscapes. These local resources involve above all producing identity for tourist cultural consumption. However, the endowment of these resources with symbolic power opens up questions about their authenticity. It also questions the interplay between “heritage” and “hospitality values” intended for tourist development. Using an ethnographic approach, our findings advance understandings about the interplay of hospitality, heritage and social memory with authenticity in a rural world experiencing dramatic socio-economic changes under the incidence of globalization.

Water is of vital and critical importance to ecosystems and human societies. The effects of human activities on land and water are now large and extensive. These reflect physical changes to the environment. Global change such as urbanization, population growth, socioeconomic change, evolving energy needs, and climate change have put unprecedented pressure on water resources systems. It is argued that achieving water security throughout the world is the key to sustainable development. Studies on holistic view with persistently changing dimensions is in its infancy. This study focuses on narrative review work for giving a comprehensive insight on the concept of water security, its evolution with recent environmental changes (e.g., urbanization, socioeconomic, etc.) and various implications. Finally, it presents different sustainable solutions to achieve water security. Broadly, water security evolves from ensuring reliable access of enough safe water for every person (at an affordable price where market mechanisms are involved) to lead a healthy and productive life, including that of future generations. The constraints on water availability and water quality threaten secured access to water resources for different uses. Despite recent progress in developing new strategies, practices and technologies for water resource management, their dissemination and implementation has been limited. A comprehensive sustainable approach to address water security challenges requires connecting social, economic, and environmental systems at multiple scales. This paper captures the persistently changing dimensions and new paradigms of water security providing a holistic view including a wide range of sustainable solutions to address the water challenges.

Marine social-ecological systems (SES) have been providing important cultural, social, and economic services for many centuries. They are, however, increasingly threatened by fast changing environmental, ecological, and socio-economic conditions. As historical marine research is increasingly developing into a multidisciplinary endeavour, it offers outstanding points of departure to analyse historic events and the response and adaptation of the respective SES. Such knowledge helps to inform today’s fisheries management and promotes successful management of changing ecosystems. Here, we compile and analyse historical data (1890–1950) of the German Western Baltic Sea fishery SES. This period is characterised by a series of strong impacts due to political, technological, economic, and ecological changes, such as two world wars, a global economic crisis, and other economic or ecological disasters. In our opinion, potential negative effects of those events were in the past attenuated by the system’s high capacity to adapt. However, most of the fishers´ historic options on how to respond and adapt have recently become no longer available. New threats (e.g. climate change) have emerged instead. We conclude that today’s fisheries management needs to integrate options of adaptation by exhausting all present or future opportunities. Adaptive fisheries management should not only focus on environmental change but need to include socio-economic change as well.

Models are essential to assess the socio-economic credentials of new agroforestry systems. In this study, we showcase robust optimisation as a tool to evaluate agroforestry’s potential to meet farmers’ multiple goals. Our modelling approach has three parts. First, we use a discrete land-use model to evaluate two agroforestry systems (alley cropping and silvopasture) and conventional land uses against five socio-economic objectives, focusing on the forest frontier in eastern Panama. Next, we couple the land-use model with robust optimisation, to determine the mix of land uses (farm portfolio) that minimises trade-offs between the five objectives. Here we consider uncertainty to simulate the land-use decisions of a risk-averse farmer. Finally, we assess how the type and amount of agroforestry included in the optimal land-use portfolio changes under different environmental, socio-economic and political scenarios, to explore the conditions that may make agroforestry more attractive for farmers. We identify silvopasture as a promising land use for meeting farmers’ goals, especially for farms with less productive soils. The additional labour demand compared to conventional pasture, however, may prove an important barrier to adoption for farms facing acute labour shortages. The selection of agroforestry responded strongly to changes in investment costs and timber prices, suggesting that cost-sharing arrangements and tax incentives could be effective strategies to enhance adoption. We found alley cropping to be less compatible with farmers’ risk aversion, but this agroforestry system may still be a desirable complement to the land-use portfolio, especially for farmers who are more profit-oriented and tolerant of risk.

Low socio-economic status is associated with a higher prevalence of depression, but it is not yet known whether change in socio-economic status leads to a change in rates of depression. To assess whether longitudinal change in socio-economic factors affects change of depression level. In a prospective cohort study using the annual Belgian Household Panel Survey (1992-1999), depression was assessed using the Global Depression Scale. Socio-economic factors were assessed with regard to material standard of living, education, employment status and social relationships. A lowering in material standard of living between annual waves was associated with increases in depressive symptoms and caseness of major depression. Life circumstances also influenced depression. Ceasing to cohabit with a partner increased depressive symptoms and caseness, and improvement in circumstances reduced them; the negative effects were stronger than the positive ones. The study showed a clear relationship between worsening socio-economic circumstances and depression.

Mountains are climate change hotspots and their ecosystems are key components in the supply of ecosystem goods and services to local communities. Low-income communities that directly depend on mountain resources are highly vulnerable to the harsh impacts of climate change. Using rainfall and temperature trends, and data collected from a household questionnaire survey, the objective of this study is to assess the impact of climate change on low-income households living in the Maluti-a-Phofung Municipality part of the Drakensberg Mountains. Climatic data were obtained from Climate Explorer while the household data were collected from a sample of 383 households in the villages of Qwaqwa. The results show that temperature and rainfall changes have significantly increased over a period of 120 years. About 51 percent of the respondents experienced extreme weather events which has the greatest impact on their households followed by drought (25.5%). Employment status was found to be significantly associated with the perception that hazards negatively impact natural resource availability, with 54% of those who had this perception being unemployed. In addition, income was found to have a significant relationship with extreme weather impacts on households and 60% of those households had a low monthly income of ZAR 2000 or less. Based on these findings, mountain households along the Drakensberg Mountains in Qwaqwa villages are already experiencing the negative impacts of climate change and their socio-economic characteristics indicate very low levels of adaptation capacity.

Forests are subject to a huge variety of often competing socio-economic demands and environmental change. This paper assesses the related conflicts that occur along what we label to be a “Global Forest Environmental Frontier”. Assessing 11 contributions to a special issue on the same topic, it summarizes the main contents of these papers and concludes with an assessment of major trends. The contributions to the special issue take both a regional and topic-related approach, assessing forest environmental conflicts on all five forested continents and investigating issues such as forest biodiversity conservation, climate change adaptation and mitigation, environmental justice and equity, development, and forest management and conservation discourses. Taken together, they provide an overview on the multiple facets of the Global Forest Environmental Frontier, but also identify some shared patterns and trajectories, which are outlined at the end of this paper.
