Abstract and Figures

Whilst future air temperature thresholds have become the centrepiece of international climate negotiations, even the most ambitious target of 1.5 °C will result in significant sea-level rise and associated impacts on human populations globally. Of additional concern in Arctic regions is declining sea ice and warming permafrost which can increasingly expose coastal areas to erosion particularly through exposure to wave action due to storm activity. Regional variability over the past two decades provides insight into the coastal and human responses to anticipated future rates of sea-level rise under 1.5 °C scenarios. Exceeding 1.5 °C will generate sea-level rise scenarios beyond that currently experienced and substantially increase the proportion of the global population impacted. Despite these dire challenges, there has been limited analysis of how, where and why communities will relocate inland in response. Here, we present case studies of local responses to coastal erosion driven by sea-level rise and warming in remote indigenous communities of the Solomon Islands and Alaska, USA, respectively. In both the Solomon Islands and the USA, there is no national government agency that has the organisational and technical capacity and resources to facilitate a community-wide relocation. In the Solomon Islands, communities have been able to draw on flexible land tenure regimes to rapidly adapt to coastal erosion through relocations. These relocations have led to ad hoc fragmentation of communities into smaller hamlets. Government-supported relocation initiatives in both countries have been less successful in the short term due to limitations of land tenure, lacking relocation governance framework, financial support and complex planning processes. These experiences from the Solomon Islands and USA demonstrate the urgent need to create a relocation governance framework that protects people’s human rights.

Abstract
Whilst future air temperature thresholds have become the centrepiece of international climate negotiations, even the most
ambitious target of 1.5 °C will result in significant sea-level rise and associated impacts on human populations globally. Of
additional concern in Arctic regions is declining sea ice and warming permafrost which can increasingly expose coastal areas to
erosion particularly through exposure to wave action due to storm activity. Regional variability over the past two decades
provides insight into the coastal and human responses to anticipated future rates of sea-level rise under 1.5 °C scenarios.
Exceeding 1.5 °C will generate sea-level rise scenarios beyond that currently experienced and substantially increase the propor-
tion of the global population impacted. Despite these dire challenges, there has been limited analysis of how, where and why
communities will relocate inland in response. Here, we present case studies of local responses to coastal erosion driven by sea-
level rise and warming in remote indigenous communities of the Solomon Islands and Alaska, USA, respectively. In both the
Solomon Islands and the USA, there is no national government agency that has the organisational and technical capacity and
resources to facilitate a community-wide relocation. In the Solomon Islands, communities have been able to draw on flexible land
tenure regimes to rapidly adapt to coastal erosion through relocations. These relocations have led to ad hoc fragmentation of
communities into smaller hamlets. Government-supported relocation initiatives in both countries have been less successful in the
short term due to limitations of land tenure, lacking relocation governance framework, financial support and complex planning
processes. These experiences from the Solomon Islands and USA demonstrate the urgent need to create a relocation governance
framework that protects people’s human rights.

... Climate change impacts are worsening around the globe with millions of individuals already vulnerable to sea level rise, flooding, erosion, wildfire, and extreme weather [1]. For instance: Arctic communities, such as Shishmaref, Alaska, United States, and Tuktoyaktuk, Northwest Territories, Canada, face rapid rates of warming and are highly vulnerable to coastal flooding and erosion [2]; equatorial communities in Small Island Developing States (SIDS) (e.g., Fiji, Tuvalu, Kiribati) are exposed to severe hurricanes and rising sea levels, resulting in heightened vulnerability [3]; and, communities in Australia face raging wildfires and worsening flood events that contribute to accentuated vulnerability [4]. Around the world, climate impacts have repeatedly wiped-out infrastructure and utilities, destroyed private property, and pose an imminent threat to resident safety. ...
... Their list includes, for example, the identification of one local organization to lead relocation efforts, the streamlining of planning and development regulations, existence of a relocation champion and political will, and provision of basic infrastructure in the resettlement site [4]. Included scholarship also points to the utility of employing a proactive planning approach, noting that this approach affords the community time to consult with stakeholders, account for contextual factors that may influence relocation goals, and identify sources of funding, among other considerations (e.g., [2,12]). ...
... For instance, several articles found that existing institutions, such as insurance and national climate policy, tend to incentivize protection in place and rebuilding over relocation [34,76,77]. Additionally, included literature emphasizes that while international policy progressively incorporates relocation content, national and local policy guidance is limited [2,74]. ...

Overview of Sustainable Water Management Policies in Cities in Terms of Preventing Climate Change Impacts: Center/Bilecik- Türkiye Case
Article
Full-text available
  • Feb 2025
Water is a vital resource for the world and humanity and is an essential issue for sustainable development. According to sustainable development goals, access to water in the required quantity and quality is everyone's most fundamental right. While the water resources in the world cover two-thirds of the globe, the distribution of water resources on the globe varies; due to the climate crisis and pollution, clean water resources are decreasing day by day. The pressure on water resources is increasing day by day with the increase in competition in agriculture, industry and domestic use. The main goal of the study is to ensure sustainable water resources management in Bilecik city center. Within the scope of the study, it aims to determine how the resources will be used more efficiently to meet the rapidly increasing water demand, how the water resources in the city center will be affected by the population growth, how the need for alternative resources and management will be done, and strategies for water recovery and reuse. According to the research conducted, the average daily amount of water drawn per person was calculated as 228 liters. In three major cities, the average amount of water drawn per capita was determined to be 190 liters for Istanbul, 246 liters for Ankara, and 221 liters for Izmir. In this context, the strategies developed and implemented for cities were evaluated specifically for Bilecik (Center). All the city's drinking water is provided by the Karasu Stream. Drinking and utility water network service is provided to 99% of Bilecik's population. (Bilecik Municipality Performance Program, 2023). It was obtained from the interview with Bilecik Municipality officials that the instantaneous water flow rate according to the population in Bilecik (Center) in 2023 was 181 liters. According to the obtained data, Bilecik (Center) remains below the average amount of water drawn per capita. Considering that the population will increase regularly with the increase in industry in the coming years in Bilecik province, there may be a water supply problem in the city soon. Strategic development targets should be determined in order to increase the efficient use of water resources in urban areas and projects that will support them should be implemented. Another important issue in increasing the quality of water resources and reducing water losses is that the water and wastewater infrastructure should be well designed. Therefore, it is envisaged that General Directorate of State Hydraulic Works (GDSH), governorships and local governments urgently develop a B plan to prevent a water crisis.

One Health on islands: Tractable ecosystems to explore the nexus between human, animal, terrestrial, and marine health
Article
Full-text available
  • Nov 2024
Islands play a central role in understanding the ecological and evolutionary processes that shape life but are rarely used to untangle the processes that shape human, animal, and environmental health. Islands, with their discrete human and animal populations, and often well-studied ecological networks, serve as ideal natural laboratories for exploring the complex relationships that shape health across biomes. Relatively long coastlines and, in some cases, low lying topography also make islands sentinels for climate change. In this article, we examine the potential of islands as valuable laboratories and research locations for understanding the One Health nexus. By delving into the challenges faced in island settings, we provide valuable insights for researchers and policymakers aiming to globally promote and apply One Health principles. Ultimately, recognizing the interconnected health of humans, animals, and the environment on islands contributes to efforts aimed at promoting global health and sustainability.

Progress and gaps in climate change adaptation in coastal cities across the globe
Article
Full-text available
  • Aug 2024
Coastal cities are at the frontlines of climate change impacts, resulting in an urgent need for substantial adaptation. To understand whether, and to what extent, cities are on track to prepare for climate risks, this paper systematically assesses the academic literature to evaluate evidence on climate change adaptation in 199 coastal cities worldwide. Results show that adaptation in coastal cities is rather slow, of narrow scope and not transformative. Adaptation measures are predominantly designed based on past and current—rather than future—patterns in hazards, exposure and vulnerability. City governments, particularly in high-income countries, are more likely to implement institutional and infrastructural responses, whereas coastal cities in lower-middle-income countries often rely on households to implement behavioral adaptation. There is comparatively little published knowledge on coastal urban adaptation in low- and middle-income countries, and regarding particular adaptation types such as ecosystem-based adaptation. These insights make an important contribution for tracking adaptation progress globally and help to identify entry points for improving adaptation of coastal cities in the future.

... Developing an adaptation strategy to coastal floods and SLR with increasing risk perception and awareness at the community level is a key element toward successful DRR and a more resilient society (Weber 2010;Shameem et al. 2015;Mucova et al. 2021;Roy et al. 2022). Given that SLR is a long-term phenomenon induced by climate change (Ali and Syfullah 2017), the governments in many other countries planned for their citizens living in coastal low-lying lands to be relocated to safer areas owing to SLR-related risk (Kniveton 2017;Albert et al. 2018). Flexible adaptation measures should be prepared to enhance the coping capacity to deal with such coastal hazard risks, including SLR (Haque et al. 2016;Jamero et al. 2017;Markphol et al. 2021). ...
The Gaps Between Institutional and Practical Disaster Risk Management Measures on Coastal Flood Risks in South Korea’s Coastal Communities
Article
Full-text available
  • Aug 2024
Global warming and climate change significantly increase the frequency of coastal floods caused by sea level rise (SLR) as a permanent factor and hydrometeorological hazards as tentative factors. The combined risks will affect coastal communities. South Korea is gradually facing SLR risks, mainly in its southern coastal regions; however, disaster risk reduction (DRR) in coastal regions remains fragmented. This study aimed to investigate the status of DRR for coastal communities in South Korea by looking at government practices and testimonies from residents. This study reviewed DRR-related regulations and documents and collected data from interviews with local government officials, field visits, and informal conversations with residents in six coastal communities. The findings show that the coastal communities were less resilient to coastal floods than to other hazards, such as typhoons and heavy rains, and the potential consequences could be expanded due to demographic challenges, fragmented institutional systems, and low risk awareness. Moreover, this study emphasized the necessity of an integrated approach to reducing the impact of coastal floods caused by both SLR and other factors. It also highlighted the importance of coastal community engagement in local DRR activities through increasing risk awareness and adapting to environmental change based on appropriate risk information disclosure by the government. The impacts of coastal floods triggered by SLR and other hazard factors can be reduced by aligning practical regulatory measures with adaptive strategies and enhancing the disaster resilience of coastal communities.

Climate change and the planned relocation of people: A longitudinal analysis of Vunidogoloa, Fiji
Article
  • Jan 2025
  • AMBIO
Rising sea levels under a changing climate will cause permanent inundation, flooding, coastal erosion, and saltwater intrusion. An emerging adaptation response is planned relocation, a directed process of relocating people, assets, and infrastructure to safer locations. Climate-related planned relocation is an unfolding process, yet no longitudinal studies have examined outcomes over time. Vunidogoloa, a low-lying coastal village in Fiji, relocated to higher land in 2014. This paper considers the dynamic outcomes of relocation, based on qualitative data collected between 2015 and 2023. It examines: residents’ changing experience of climate and environmental risk; governance and decision-making processes over time; improved access to many resources and services along with incomplete infrastructure; opportunities and threats to health; and changing social organization and place-based values. The paper foregrounds change over time and provides in-depth examination of dynamic planned relocation experiences and (mal)adaptation outcomes in Vunidogoloa, Fiji.

The preparedness of schools in responding to emerging climate change impacts and risks in Bhutan: A Bourdieusian analysis
Article
  • Nov 2024
Climate change is accelerating, and it is becoming clearer that the education sector in countries around the world will bear the brunt of the effects. Research into the impacts of climate change on schools and children as well as their engagement in responses is still sparse, albeit growing. In this paper, Bourdieu’s concepts of field, habitus, and capital are applied to better understand the practice of school climate response and the role schools may have in climate action. The analysis is based on interviews with Bhutanese school leaders, teachers, and district education officials. The results indicated that the school system and learners experienced multiple impacts and shocks. Opportunities to engage in practices for climate response were constrained by access to capital (cultural & economic) and policy and institutional structures. Socio-cultural dispositions showed a noteworthy influence on school stakeholders’ engagement in environmental and climate response interventions. Social capital acted as a catalyst for initiating environmental and climate change actions, carried out through collective school, community, and student-based activities. This research adds to the literature by exploring opportunities for social transformation that may lead to more effective practices in school climate action and more broadly, the scope of Bhutanese schools to respond to socio-scientific issues in science education.

Climate change and migration: the case of the Pacific Islands and Australia
Article
Full-text available
  • Jan 2016
  • Pac Stud
There is growing consensus that voluntary labour migration can promote economic development in migrant sending and receiving countries and can be a positive adaptive response to the effects of climate change. However, for voluntary migration to be a positive form of adaptation, policy commitment and collaboration between migrant sending and receiving countries will be required. In the Pacific, Australia has capacity to collaborate with Pacific Island governments to facilitate voluntary migration; however, Australia has been reluctant to expand migration access to the Pacific. This article makes the case for promoting migration opportunities between Australia and the Pacific as part of the adaptive strategy efforts.

Customary Land and Climate Change Induced Relocation—A Case Study of Vunidogoloa Village, Vanua Levu, Fiji
Chapter
Full-text available
  • Feb 2017
Increasingly unremitting weather patterns and rising sea levels have obligated Fiji to become one of the first countries in the South Pacific to relocate communities due to climate change. The customary lands reflect the traditional and communal structure of the indigenous Fijians and parting from it as a consequence of forced relocation is a delicate and vulnerable issue that establishes some of the negative effects of population displacement. Relocation to a new land signifies separation from uniquely adapted traditions that took thousands of years to form. The purpose of this paper is to explore the cultural, social, environmental and economic impacts of climate change induced displacement on the people of Vunidogoloa village and generate suggestions for consideration of socioeconomic and customary aspects in the much anticipated institutional relocation strategies. The paper achieves its purpose through experiences of the people of Vunidogoloa village, in light of the interviews and discussions carried out at the village and interviews conducted with the relevant government officials. In addressing this objective the paper analyses the main constraints of resettlement, the land-people bond, governance, and funding. The paper concludes by providing recommendations essential for national policy guidelines and communities in the South Pacific and in the other parts of the world that face or will face similar challenge.

Coastal sea level rise with warming above 2 °C
Article
Full-text available
  • Nov 2016
Significance Warming of 2 °C will lead to an average global ocean rise of 20 cm, but more than 90% of coastal areas will experience greater rises. If warming continues above 2 °C, then, by 2100, sea level will be rising faster than at any time during human civilization, and 80% of the global coastline is expected to exceed the 95th percentile upper limit of 1.8 m for mean global ocean sea level rise. Coastal communities, notably rapidly expanding cities in the developing world; small island states; United Nations Educational, Scientific and Cultural Organization Cultural World Heritage sites; and vulnerable tropical coastal ecosystems will have a very limited time after midcentury to adapt to these rises.

Longitudinal assessment of climate vulnerability: a case study from the Canadian Arctic
Article
Full-text available
The Arctic is a global hotspot of climate change, which is impacting the livelihoods of remote Inuit communities. We conduct a longitudinal assessment of climate change vulnerability drawing upon fieldwork conducted in 2004 and 2015 in Ikpiarjuk (Arctic Bay), Nunavut, and focusing on risks associated with subsistence harvesting activities. Specifically, we employ the same conceptual and methodological approach to identify and characterize who is vulnerable, to what stresses, and why, assessing how this has changed over time, including re-interviewing individuals involved in the original study. We find similarities between the two periods, with many of the observed environmental changes documented in 2004 having accelerated over the last decade, exacerbating risks of land use: changing sea ice regimes and wind patterns are the most widely documented at both times, with new observations reporting more frequent sighting of polar bear and orca. Socio-economic and technological changes have altered the context in climate change impacts are being experienced and responded to, both exacerbating and moderating vulnerabilities compared to 2004. The adoption of new technology, including GPS and widespread use of the internet, has helped land users manage changing conditions while sharing networks remain strong, despite concern noted in the 2004 study that they were weakening. Challenges around access to financial resources and concern over the incomplete transmission of some environmental knowledge and land skills to younger generations continue to increase sensitivity and limit adaptive capacity to changing climatic conditions.

Applying Past Lessons Learned to the Relocation of Climate Change Induced Transboundary Displaced Persons
Article
  • Oct 2016
This study aims to identify a useful and practical methodology to rehabilitate the livelihoods of climate change induced transboundary displaced persons (CCITDP) after they move to developed nations, in particular those from the Small Island Developing States in the Pacific Ocean. Migration sometimes causes conflicts among migrants, or between migrants and those in the host community. Such conflicts could be avoided or mitigated by examining the 67 lessons learned from people's past resettlement experiences—from those displaced by large infrastructure development projects in Asia and the Pacific or from evacuees of Fukushima due to the nuclear power plant disaster—and using these experiences to better cope with the emergence of CCITDP. Evacuees of an island that is sinking due to sea-level rise may be regarded as either voluntary migrants or CCITDP depending on when they leave the island. Although, lower-class people, who are vulnerable to hardships, will need to leave their homes earlier than wealthier people. These two groups of migrants should be assisted equally to avoid conflicts between the two groups because they may live in the same place after relocation and also to discourage them from staying on the island until they are entitled to assistance as CCITDP. Not all migrants will miss family bonds after relocation, and some may actually enjoy their emancipation from old customs by moving to a new place. The best destination for the first generation of migrants may differ from the best destination for their children.

Managed retreat as a response to natural hazard risk
Article
  • Mar 2017
Managed retreat is a potentially important climate change adaptation option, providing an alternative to structural protection or accommodation measures to manage natural hazard risk. However, its application faces challenges given the projected scale of climate-induced displacement and the difficulties of resettlement. We evaluate the drivers, barriers and outcomes of 27 recent cases of managed retreat that have resettled approximately 1.3 million people. A conceptual model based on two key factors—who benefits from retreat and who initiates it—organizes the diverse set of cases into four quadrants. Different sociopolitical dimensions emerge as particularly influential in each quadrant. The model establishes a foundation for understanding and anticipating case-specific complexities. It can be used to unpack the landscape of managed retreat and evaluate its potential future applications.

Forward planning to maintain the attractiveness of coastal areas: Choosing between seawalls and managed retreat
Article
  • Jun 2017
  • ENVIRON SCI POLICY
This paper aims to inform forward-planning policies in the face of sea-level rise due to climate change, focussing on the choice of reducing the vulnerability of property at risk through managed retreat or protection behind seawalls. This adaptation is important not only to reduce the cost of future damage but also to maintain the beaches which are an attractive feature for tourism, of vital importance for coastal areas. Some 421 residents with main and secondary homes were surveyed in Hyères-les-palmiers in the Var department (Southeast France). The survey sought to compare the willingness of residents to contribute financially to building a seawall or to relocating sea-front property. Preferences depend both on common variables and variables specific to the proposed arrangement. They reveal common concerns focused on effectiveness and the determining factor of property ownership. The results also show some awareness of the long-term advantages of managed retreat, despite some opposition from older people, who are also more sceptical about the reality of the risk incurred.

The complex decision-making of climate-induced relocation: adaptation and loss and damage
Article
  • Dec 2016
Climate change is increasingly challenging the ability of millions of people to sustain livelihoods as the places where they live become uninhabitable. The relocation of populations as individuals, households, and communities within countries and across international borders demonstrates the complexity of climate change impacts. Looking at the literature, some researchers argue that relocation caused by climate change can be an effective strategy to adapt to localized changes, whereas others argue that the movement away from ones' homeland is more neatly captured in the climate change lexicon as ‘loss and damage’. We argue here that the relocation of people as a result of the impacts of climate change can be both adaptation and loss and damage. Drawing on examples from Alaska and Kiribati, we show that dividing this issue between the two concepts is unhelpful in resolving key issues around the types of appropriate support for these transitions to sustain and protect livelihoods and to open up possibilities for self-determined futures. Policy Relevance Climate-induced relocation poses a significant challenge for the populations affected as well as the government agencies tasked with providing technical assistance and funding. At present, policies and institutional frameworks have not yet been developed to accommodate these challenges, despite the urgent need to do so. When the relocation of populations can be planned, participatory, and people centred, then it can be an adaptation strategy that will protect people from the permanent loss of land and livelihoods. If these movements are decided, driven, managed, and undertaken by those affected, then there is the potential for the relocation to also be a transformative opportunity for people to respond to the impacts of climate change, and sustain their livelihoods and possibly even improve certain livelihood outcomes. However, these relocations also cause significant loss and damage. The extent of the loss and damage will partly depend on the ability to have these relocations planned and ensure that human rights protections are embedded in institutional frameworks. The article shares a series of lessons and learnings that are of policy relevance at a variety of scales.
