Displaced by nature, driven by choice: Exploring the factors influencing environmental migrants' habitat preferences in coastal Bangladesh

This study examines the factors influencing environmental migrants’ habitat preferences in southwestern Bangladesh. Using a multi-stage sampling technique, we selected 408 households in rural and urban areas, who had moved to their current locations due to climatic extremes. We applied relevant regression models to analyze the complex interplay of socioeconomic, environmental, and institutional factors shaping migration decisions. Our empirical results suggest that, despite having greater access to services in cities, migrants reported lower levels of well-being than their rural counterparts, which could be attributed to reduced social cohesion and limited opportunities for participation in decision-making. Disaster preparedness, early warning access, and prolonged exposure to environmental hazards significantly influence migration decisions and well-being. Protracted post-disaster suffering increases the likelihood of migration to urban slums, emphasizing the vulnerability of rural populations. Men are more likely than women to migrate to urban areas, possibly due to perceived employment opportunities. Surprisingly, while slum dwellers have better service access, their well-being scores are lower than rural residents. Access to education, healthcare, safe drinking water, and early warning systems are all crucial determinants of well-being. Policy recommendations include improving disaster preparedness and early warning systems in rural areas, developing targeted interventions for urban slum migrants focused on social cohesion and income diversification, and implementing gender-specific support programs. This research contributes to understanding environmental migration dynamics in Bangladesh and informs policymakers about sustainable resettlement strategies. Future studies should explore non-linear relationships and expand to diverse geographical contexts.

Analysing Amitav Ghosh’s <i>Gun Island</i> as a Climate Fiction: Transgressing ‘Borders’ and ‘Orders’ by the Humans and Nonhumans

Amitav Ghosh has a tendency to write literary pieces focusing on climate issues. This aspiration is also manifested in his novel Gun Island (2019). The author allegorizes the myth of Manasa Devi, which creates a wonderful connection between humans and natural environment in this novel. Gun Island (2019) explores the conviction of diversified environmental issues, such as environmental injustice, migrant ecologies, and climate refugees. Although natural disasters occur more or less everywhere in the world, the poor pay the highest price. The harsh reality is that the most affected are the most marginalized regions of underprivileged countries. Developed countries can still cope with its effects, but people in poor countries are persistently being displaced. The Sundarbans is one such magnificent instance in Gun Island. Overall, Ghosh has shown that migration of humans and nonhumans occurs simultaneously as a result of climate change. Humans and nonhumans transgress the precincts of ‘border’ as well as ‘order’ to migrate from one place to another eco-friendly place. His perplexing story of Gun Island is inexplicably mythical but contextually practical because it resonates with a group of Asian and African people’s own experiences, emotions and their yearning for migration to Europe due to climate change. This borderless migration cannot be stopped by any means of order.

Will They Continue to Endure: How Conflict and “Climate-Induced” Migration is Affecting the Lake Chad Region

The effects of climate change are undoubtedly global. Reports show that West Africa is in a precarious position, regarding some of the worst consequences of climate change, occasioning extreme events, such as violent conflict, insecurity, and loss of livelihoods in the Lake Chad region. The impact on human lives is full-blown as ‘climate-induced’ migration results in drought, desertification, and the intensifying water stress has on human migration in the region. Notably, the deterioration of individual and local living conditions has compelled inhabitants of the region in Nigeria to migrate to neighboring states as Internally Displaced Persons (IDPs) or ‘environmental refugees” in neighboring countries. However, existing studies focused on the impact and patterns of migration in West Africa thereby creating a “knowledge gap” on how ‘climate-induced’ migration is affecting the Lake Chad region. This paper employs secondary data collection, analyzing dynamic trends and patterns of climate change and challenges management. Findings revealed that while the activities of terrorists and insurgent groups have strongly impacted migration within the Lake Chad region, the continuous “dryness” and the ever-changing climate conditions, such as rising temperature, desertification, flooding, and drought have dramatically worsened and contributed to the mass decision to leave the region.

An Inquiry on the Legal Status and Protection of Climate Refugees from an International Law Perspective

An Inquiry on the Legal Status and Protection of Climate Refugees from an International Law Perspective

Climate change and forced migration

Abstract Climate change is increasingly recognized as a significant driver of migration patterns worldwide. As the global temperatures rise, extreme weather events become more frequent, leading to disruptions in livelihoods displacement, and migration. Every day, climate change becomes a more urgent economic, social and existential threat to countries and their people. Climate changes are becoming more and more evident every day, a factor that undoubtedly directly or indirectly affects the displacement of populations. This article provides answers to basic questions starting with how, and where climate change triggers migration and displacement, the second question is if we have a definition for the climate migration, or climate refugee, can they have protection from the Convention relating to the Status of Refugees and the last analysis is the inadequacy of the protection afforded by international law and European Union law and the Albania Legislation to individuals who leave their country of origin for reasons related to environmental issues. The methodology used to answer the questions of this paper includes desk review on existing literature, legal texts, reports from international organizations, legal framework regulating climate migration rights and the decision of the UN Human Rights Committee (HRC) regarding the “climate refugees”, the case of Teitiota v New Zealand.

Effects of climate change on migration in Latin America and Caribbean: a scoping review

Climate change-induced natural disasters such as hurricanes, landslides, forest fires, and changes in precipitation directly affect rural sectors that depend on field production and other dimensions of everyday life. This generates the mobilization of people from their homes to safer places within the same country or across borders. There is a lack of information on the impacts of climate change on environmental migrants in Latin America and the Caribbean (LAC). This scoping review aims to describe the scientific evidence of the health effects of climate change on migrant in LAC. The review was conducted using databases from PubMed, Web of Science (WoS), and Google Scholar in English, Spanish and Portuguese. After screening the title, abstract, and full text of identified hits (n = 726), 31 records were finally included. Evidence indicates that climate change relates to health and healthcare, psychosocial and infrastructure dimensions among migrants in LAC. Health effects refer to limited access to healthcare, underdiagnosis, increased susceptibility to diseases and mental health conditions like stress and anxiety. Psychosocial dimensions refer to a heightened risk of sexual and gender-based violence, social marginalization, family separation, and loss of identity and culture. Infrastructure refers to environmental degradation and agricultural and urban infrastructure destruction. Multiple adaptations to these conditions are described among migrant populations in the region. Recommendations for improvements are presented. This scoping review suggests climate change’s significant health, psychosocial, and infrastructural associations with migrants in Latin America.

Molecular insights into the binding mechanism of strontium and cesium on phyllosilicates with different expandability

The environmental fate of strontium (Sr) and cesium (Cs), as the critical radioactive fission products, have raised significant concerns regarding radioactive waste disposal and environmental protection. The current study investigated the distinction in the binding configurations of Sr2+ and Cs+ on various 2:1 phyllosilicate (illite, vermiculite, and montmorillonite) by combining batch adsorption, sequential extraction, and spectroscopic analyses. The results show that strontium adsorption is strongly influenced by pH as well as ionic strength, while there is no significant variability in strontium adsorption by different types of clay minerals. EXAFS analysis confirms the outer complexation of strontium on the planar sites of the clay minerals, i.e., Sr2+ is surrounded by ~8.0 O atoms, RSr-O ≈ 2.6 Å, and that process is mainly realized by ion exchange. In contrast, Cs+ adsorption was markedly influenced by the variety of clay minerals but less by pH and ionic strength, the presence of humic acid (HA) inhibited Cs+ adsorption. The inner-sphere complexation formed mainly at the frayed edge sites on illite, and interlayer sites on vermiculite and montmorillonite, was the dominant mechanism for Cs+ adsorption. In addition, the collapse of the interlayer space of vermiculite induced by Cs+ adsorption on the interlayer sites was responsible for the more stable and irreversible immobilization. The findings in present work highlighted the significance of prevailed mineral in governing environmental migration risk of radionuclides, the revealed adsorption mechanism and binding configuration of Sr2+ and Cs+ on typical phyllosilicates would be referable in constructing a reliable migration model of Sr2+ and Cs+ in natural media.

Beyond environmental determinism? Analysing studies on environmental migration in the Greater Mekong Subregion and the Ganges‐Brahmaputra Delta Region

AbstractCurrent studies often present environmental and climate migration in three ways: in an environmentally deterministic way, as an adaptation strategy or as a ‘wicked’ phenomenon. This bibliometric and thematic analysis analysed 147 studies from January 2015 until August 2020 on environmental migration in the Greater Mekong Subregion and the Ganges‐Brahmaputra Delta Region (India and Bangladesh) to determine to what extent dominant discourses on environmental migration and mobilities have moved away from environmental determinism. Results of this study suggest that most analysed studies, which clearly framed environmental migration, tend to remain rather environmentally deterministic. Further, the spatial level of analysis in the studies, whether it was local or non‐local, did not correspond to different theoretical and conceptual approaches to environmental migration. While 17.0% of the studies presented environmental migration as a form of adaptation, relevant discussions on the concepts of resilience, vulnerability and adaptation were largely lacking. This is problematic as recent global studies on environmental migration are increasingly adopting the adaptation paradigm. Additionally, relatively few studies have adopted more critical or pluralistic approaches to human mobility, climate change and adaptation. Lastly, studies on Bangladesh were more often presenting climate change as a primary driver of migration than studies in other localities within the study region.

Impact of shifting from rice to shrimp farming on migration aspirations in Bangladesh

AbstractThe Ganges–Brahmaputra–Meghna delta is one of the most populous deltas in the world, threatened by diverse environmental stressors, including salinity intrusion, causing adverse consequences on livelihood adaptation. Shrimp farming has been recognized as one of the most practiced livelihoods among various livelihood opportunities. Growing global demand and higher economic returns encouraged many farmers to convert their agricultural land to shrimp farms by intruding saline water into the farmlands to produce shrimps. In this study, we investigated whether the growing trend of shrimp farming influences the migration aspirations of the vulnerable coastal communities in Bangladesh. The study employed qualitative interviews with individuals in four villages in southwest coastal Bangladesh. Satellite images were analyzed to detect land-use changes and changes in soil salinity in the last 28 years, confirming a rapid increase in shrimp farms. Results from the qualitative interviews indicate that poor people with limited resources cannot produce paddy on their land because of increased soil salinity caused by shrimp farming. Such a situation leads them to aspire to migrate. Thus, our analysis contributes to the discourse on “aspiration and capability” in environmental migration by adding the impacts of land-use changes on livelihoods.

Systematic Mapping of Climate Change Impacts on Human Security in Bangladesh

There is an increasing consensus that climate change undermines human security by exacerbating existing challenges, acting as a “threat multiplier”. Bangladesh is a climate hot spot due to its geographical location, dense population and vulnerable socio-economic infrastructure. Although there is an increasing number of studies on the impacts of climate change in Bangladesh, aggregated research that combines this evidence and provides a comprehensive overview is lacking. The aim of this research is to thoroughly investigate the characteristics of the academic literature on the complex pathways through which climate variability affects different components of human security in Bangladesh, allowing for determination of the trends and research gaps, as well as whether they lead to conflict or cooperation. We used a systematic mapping methodology to search and screen 1839 publications in Web of Science, including 320 publications for the final synthesis. We found a predominant research focus on rural areas, especially in the southwestern region, with declining crop yield, economic loss, migration, water shortage, food scarcity and health hazards being the highlighted impacts of climate change for Bangladesh. The impacts on food, economic, environmental, health and water security have been well studied, but we found significant research gaps in some human security components, especially energy security. Women and the economically disadvantaged are disproportionately affected, and the causal pathways between conflict or cooperation and the ever-changing climate lack research efforts, implying a dire need to focus on under-researched areas before they become more complex and difficult to address. Policies and interventions should prioritise climate-resilient agricultural practices and infrastructure in high-risk areas, building local capacities and integrating climate risk assessments into urban planning, considering the high influx of environmental migrants. This systematic map provides a foundation for future longitudinal studies, establishes a baseline for this era for future comparisons and serves as a reliable database for relevant stakeholders and policy makers.

Is There a Need to Expand the Refugee Definition?

This article examines the urgency of protecting against displacement caused by climate change under international law and questions why Rohingya displacement has not been resolved even though it has been protected by international law, whether the harmonization of human rights approaches, national law, and international law towards refugees and climate refugees. This paper uses a literature review method and a normative legal approach by reviewing national and international human rights law. The findings of this paper suggest that many Rohingya continue to flee to safer countries, often taking enormous risks, including dangerous ocean crossings. The impacts of climate change can be categorized as persecution; the Refugee Convention requires that such persecution be due to race, religion, nationality, political opinion, or membership of a particular social group. Persecution alone is not enough. The difficulty is that the impacts of climate change are largely indiscriminate and not related to specific characteristics such as a person's background or beliefs. The Rohingya people have experienced violence, discrimination, and persecution for decades, and the international community has failed to protect them effectively. The international community has allowed Myanmar to carry out genocide against the Rohingya without taking any action, even though United Nations member states are obliged to protect their population from genocide, war crimes, ethnic cleansing, and crimes against humanity. National, international, and human rights laws play an important role in determining the legal status and rights of refugees in a country. All three must be embedded and integrated, starting from international law and its derivatives to national law, which contains humanitarian rights.

Research progress on environmental behavior of arsenic in Qinghai-Tibet Plateau soil

The Qinghai-Tibet Plateau, with its high altitude and cold climate, is one of the most fragile ecological environments in China and is distinguished by its naturally elevated arsenic (As) levels in the soil, largely due to its rich mineral and geothermal resources. This review provides a comprehensive analysis of As content, focusing on its distribution, environmental migration, and transformation behavior across the plateau. The review further evaluates the distribution of As in different functional areas, revealing that geothermal fields (107.2 mg/kg), mining areas (53.8 mg/kg), and croplands (39.3 mg/kg) have the highest As concentrations, followed by river and lake sediments and adjacent areas (33.1 mg/kg). These elevated levels are primarily attributed to the presence of As-rich minerals, such as arsenopyrite and pyrite. Additionally, human activities, including mining and geothermal energy production, exacerbate the release of As into the environment. The review also highlights the role of local microorganisms, particularly those from the phyla Proteobacteria and Actinobacteria, which possess As metabolic genes that facilitate As translocation. Given the unique climatic conditions of the plateau, conventional methods for As control may not be fully effective. However, the review identifies promising remediation strategies that are environmentally adaptable, such as the use of local microorganisms, specific adsorbents, and integrated technologies, which offer potential solutions for managing and utilizing As-contaminated soils on the plateau.

Addressing Impacts from Climate Change Within International Legal System: More Precise Distribution of Responsibilities

As the international challenges resulting from climate change become emergent, how to reform international law and institutions to reduce the effects of climate change has become a crucial issue. This paper carries out surveys on regulating and restructuring the present international law system about current issues and provides suggestions for further practice. We can also consider building a climate club. The existing climate regulation mechanism needs to improve, leading to problems such as carbon leakage and free riding. Climate clubs can urge countries to fulfill their obligations by rewarding member states that fulfill their obligations and cracking down on non-member states. Apart from efforts in environmental governance, the international law system should also attach attention to the issue of climate refugees as a reaction to climate change. The last article argues that international society should provide legal protection for climate refugees, and it is reasonable for them to acquire a formally defined legal status for future humanitarian care. This thesis also explores the potential role of regional bodies in addressing climate change outside of the United Nations Framework Convention on Climate Change (UNFCCC) and the legitimacy of their responsibilities based on constitutional treaties, their role in regulating the international commons, and their relationship to the UNFCCC. Based on this, this thesis suggests that regional institutions take on more responsibility in regulating state obligations and propose possible solutions to the climate change crisis. CBDR is an essential principle in the cooperation among countries to solve the problem of global climate change. It makes global cooperation fairer and more effective but also generates some problems. The main problem is that there is no clear division of responsibilities between countries, and policies must be implemented. This paper proposes three ways to divide responsibilities and argues that companies must actively participate in global emission reduction activities.

Climate Refugees in India: Seeking Security between Disaster Diplomacy and Strategic Ambiguity

Abstract Among the 100 million refugees and displaced persons in 2022, the category of “climate refugees” has become more salient, yet countries still do not know how to handle it. Two aspects of climate refugees also remain understudied; how climate refugees are perceived, since they are viewed through the dual lenses of climate risks and migratory flows and how these perceptions impact policies. Climate refugees are thus doubly impacted by the spill-over effect of securitization processes in the fields of climate change and immigration. This paper analyzes how climate- and migration-security legislation in a resource-constrained nation conceptualizes climate refugees, and how their diverse conceptual categories spill over into policymaking and create a mutually beneficial and humanitarian approach for host and migrant populations. This paper uses India as a case study based on its historical practice of refugee protection despite significant resource constraints, high risk of inbound climate refugees, participation in key global agreements, and domestic discourse over climate and immigration securitization. Using policy analysis and expert interviews, this study demonstrates that India successfully exemplifies a broadly humanitarian climate mobility regime in the South Asian region through relocations, Humanitarian Assistance and Disaster Relief operations, and ad hoc legal protection. Despite crucial structural limitations, India illustrates a democratic global south template implicitly recognizing migrants’ vulnerability to climate change and attempts to minimize risk, with potential for replication in other developing and developed nations. This normative policy framework, notwithstanding its limitations, presents an alternative to the threat-centric and unsustainable securitization of climate migration practiced in the Global North.

The role of the environment within a constellation of interacting causal factors shaping mobility—the example of three oases in Northern Africa

Northern Africa’s oases are fragile agroecosystems that, through environmental limitations on agricultural development, such as insufficient amounts of water for irrigation, have had to face a profound transformation of the environment on which livelihoods depend. A common strategy in such a situation is mobility. Though mobility responds to similar environmental limitations, the varying economic, social, demographic, and political contexts lead to divergent forms of it. Based on the mixed-method research conducted in the three oases located on the edge of the Sahara Desert (Mhamid in Morocco, El Faouar, and El Ferch in Tunisia), this paper explores the complex interplay of environmental and non-environmental factors shaping mobility. It highlights the need for a contextualization analysis of the mobility-environment nexus, illustrating how different factors’ constellations make mobility part of adaptation, coping, or escape strategies. The results reveal the dynamics of intertwined factors influencing mobility in the oases, sometimes dominated by environmental factors, other times by economic ones, and so forth. This makes their residents subject to fluid categorisation as environmental migrants, and the mobility-environmental nexus itself is highly complex.

The Effect of Climate Change Threat on Public Attitudes towards Ethnic and Religious Minorities and Climate Refugees

How does climate change threat affect attitudes towards ethnic and religious minorities and climate change refugees? We show that threatening climate change can have deep psychological effects even among social majority groups in relatively prosperous and peaceful societies. Using three survey experiments with self-identified White British participants ( N = 616, N = 587, and N = 535), we demonstrate that social majority members who are exposed to threatening information about climate change (vs. neutral information) and, at the same time, feel little national efficacy over climate change, evaluate more negatively certain ethnic and religious minorities, especially Muslims and Pakistanis. We found the same trend in the evaluation of climate refugees, although it reached statistical significance only in one of the experiments. We explain these reactions as pertaining to groups that are perceived as threatening the salient ingroup and its collective agency. Our research significantly contributes to the literature on the social and political implications of (climate change) threat, especially by focusing on boundary conditions, namely the perception of collective control in case of complex and large threats.

Disaster induced displacement and durable solutions in Africa

AbstractClimate change represents a significant challenge to the sustainability of the global economy. Many African countries have suffered the repercussions of environmental and climate deterioration, most notably internal displacement. This article sought to examine the impact of climate change within the context of internal displacement in Africa and to preview and describe the trends of internally displaced people in Africa. The study used a mixed methods approach. Qualitative data was obtained from online repositories, and it was analyzed using content analysis. Quantitative data was obtained from World Bank portal and it was analysed using descriptive statistics. Research findings have shown that Africa is plagued by a high number of internally displaced people. It was also established that climate change leads to income inequality, the exposure of people to poverty, and the destruction of infrastructure. These adverse effects affect the capacity of African economies to attain selected Sustainable Development Goals. In terms of policy recommendations, it was suggested that there is a need to strengthen the regional and continental bodies, invest in climate change adaptation measures, broaden the definition of refugees to include climate refugees, and promote robust research and capacity building.
