The scientific literature, media, international summits, and policy forums highlighted enough the people who either move or are willing to move because of environmental reasons. Still, the voluntary environmental non-migrants (ENM), who are assumed to have strong resilience and coping capacity, are inordinately overlooked. The importance of addressing these ENMs has increasingly been emphasised. First, the paper explains the characteristics of ENM, outlining the key distinction between voluntary and forced non-migrants. Second, it emphasises the need to protect populations affected by environmental change and disaster, specifically highlighting oft-neglected ENM policy gaps. Thus, it examines to what extent ENM is addressed in existing global legal and policy responses. Having identified the gaps, it further considers the importance of adaptation strategies and well-planned relocation policies to support non-migration. Finally, it summarises the existing ENM policies’ scope and reflects on the key policy gaps identified to suggest the way forward. This paper urges for a pragmatic and strategic policy approach that ensures bottom-up community-oriented approaches for supporting ENM by: (i) coordinating adaptation activities, (ii) ensuring planned relocation and migration with dignity, (iii) enabling informed decision-making, (iv) mobilising national and international support, and (v) developing appropriate institutional structures for adaptation.

In the transformation from tidal systems to freshwater coastal landscapes, plants act as eco-engineering species that reduce hydrodynamics and trap sediment, but nature and timing of the mechanisms of land creation along estuaries remains unclear. This article focuses on the Old Rhine estuary (The Netherlands) to show the importance of vegetation in coastal landscape evolution, predominantly regarding tidal basin filling and overbank morphology. This estuary hosted the main outflow channel of the river Rhine between ca 6500 to 2000 cal bp, and was constrained by peat during most of its existence. This study reconstructs its geological evolution, by correlating newly integrated geological data and new field records to varying conditions. Numerical modelling was performed to test the inferred mechanisms. It was found that floodbasin vegetation and resulting organic accumulation strongly accelerated back-barrier infill, by minimizing tidal influence. After tidal and wave transport had already sufficiently filled the back-barrier basin, reed rapidly expanded from its edges under brackish conditions, as shown by diatom analysis and datings. Reed growth provided a positive infilling feedback by reducing tidal flow and tidal prism, accelerating basin infilling. New radiocarbon dates show that large-scale crevassing along the Old Rhine River – driven by tidal backwater effect – only started as nutrient-rich river water transformed the floodbasin into an Alder carr in a next phase of estuary evolution. Such less dense vegetation promotes crevassing as sediments are more easily transported into the floodbasin. As river discharge increased and estuary mouth infilling progressed, crevasse activity diminished around 3800 to 3000 cal bp, likely due to a reduced tidal backwater effect. The insights from this data-rich Holocene study showcase the dominant role that vegetation may have in the long-term evolution of coastal wetlands. It provides clues for effective use of vegetation in vulnerable wetland landscapes to steer sedimentation patterns to strategically adapt to rising water levels.

Previous research finds that individuals tend to form ties with similar others much more often than with dissimilar others. However, we know relatively little about tie loss and to what extent this is driven by (dis)similarity. In this paper, we argue that ties to persons who are dissimilar with regard to gender, age, ethnicity, and education are lost faster than ties to similar persons – and we test three explanations for this faster decay of ties with dissimilar others: lack of meeting opportunities, preferences for similarity, and lower network embeddedness. To test these explanations, we analysed two waves of the Survey on the Social Networks of the Dutch (SSND, 2007, 2014). These SSND-waves contain comprehensive longitudinal panel data on ego networks of 441 respondents, who were interviewed about a wide range of relationships, their alters’ sociodemographic characteristics, where and when they met their alters, as well as how and whether they maintain these relationships. We modelled tie loss by event history analyses. Results show that ties to persons who were dissimilar are more likely to be lost faster, and that tie loss occurs mostly in the early years of a relationship. However, meeting opportunities, preferences for similarity, and network embeddedness are unable to explain why ties to dissimilar others are lost faster. We conclude that dissimilarity is a powerful driver of tie loss, and that more arguments and research are needed to fully understand the underlying mechanisms.

Background: Persistent rheumatic symptoms and its impact on health-related quality of life (QoL), induced by the Indian Ocean Lineage (IOL) chikungunya virus (CHIKV) genotype have been widely studied. In 2014, a major CHIKV outbreak of the Asian genotype occurred in Curaçao, after which we established a longitudinal cohort in 2015, to follow the long-term CHIKV sequalae. Currently, the long-term clinical manifestations and its impact on QoL induced by the Asian CHIKV genotype, followed prospectively through time, and the association of age and comorbidities with rheumatic symptoms persistence, 60 months (M60) after disease onset is unknown. Methods: The cohort of 304 laboratory confirmed patients were followed prospectively in time at 3–16 months (M3-16), 30 months (M30), and M60 after disease onset. Demographic and clinical characteristics, and the 36-item short-form survey (SF-36) QoL status were collected through questionnaires. At M60, QoL scores were compared to general population (CHIK-) norms. Results: A total of 169 (56%) patients participated (74.6% female, mean age 56.1 years) at all time points, 107 (63%) were classified as recovered and 62 (37%) as affected. The affected patients reported an increase in the prevalence of arthralgia (P .001) and arthralgia in the lower extremities (P

Background Little is known about the persistence and impact of non-rheumatic symptoms after acute chikungunya disease. We have studied the clinical presentation and long-term impact of rheumatic and non-rheumatic symptoms on health related quality of life (QoL) 2.5 years after disease onset. Additionally, the validity of the Curaçao Long-Term Chikungunya Sequelae (CLTCS) score in classifying disease severity over time was evaluated. Methodology/Principal findings This prospective cohort study followed 248 chikungunya patients. Symptoms and SF-36 QoL were evaluated during baseline and follow-up at 2.5 years using questionnaires. Chikungunya disease status was classified using the CLTCS-score. At 2.5 years after disease onset patients were classified as being recovered (43%), mildly (35%) or highly (22%) affected. In comparison to mildly affected, highly affected patients reported the highest prevalence of ongoing rheumatic and non-rheumatic/psychological symptoms, with increased prevalence of arthralgia in the lower extremities (p = .01) and fatigue (p = .049) over time, and higher pain intensity (p < .001). Compared to mildly affected, being highly affected was associated with weakness in the lower extremities (OR: 1.90; CI: 1.29–2.80, p = .001) and worsened physical and mental QoL impairment. Conclusions Patients are both physically and psychologically affected by rheumatic and non-rheumatic symptoms of long-term chikungunya disease. The CLTCS-score is an easy to use instrument for classifying long-term chikungunya disease severity and impact and can facilitate health care providers in identifying highly affected patients who are prone to develop severe QoL impairment. Highly affected patients are recommended to be treated in a multidisciplinary setting to improve physical and psychological functioning, and QoL.

Adaptation pathways have been conventionally viewed as an approach for planning and identifying different adaptation options and the ways in which they can be realized. However, there has been scant consideration of the wide diversity of cultural and social processes which shape how adaptation pathways emerge. We argue that a cultural lens sheds light on differential vulnerability and the processes that enable or hinder adaptation. A cultural lens focuses intrinsically on intersectional categories which can impact the adaptive agency or resilience of individuals, households, and communities. In particular, we need to examine how cultural beliefs, norms, and practices change over time, and are reflected in adaptation pathways since livelihoods do not remain the same over the life course. Additionally, taking a broader perspective by incorporating concepts from cognitive anthropology helps us understand motivations and choices which influence adaptation pathways.

Background Aedes aegypti and Aedes albopictus are primary vectors of emerging or re-emerging arboviruses that threaten public health worldwide. Many efforts have been made to develop interventions to control these Aedes species populations. Still, countries in the Latin America and the Caribbean (LAC) region struggle to create/design/develop sustainable and effective control strategies. This scoping review synthesises evidence concerning the effectiveness of Ae. aegypti and Ae. albopictus prevention and control interventions performed in LAC (2000–2021). The findings can be used to evaluate, compare and develop more effective control strategies. Methodology The review is based on the methodology by Joanna Briggs Institute for conducting a scoping review. The MEDLINE (via PubMed and Web of Science), Cochrane Library, Scopus, EMBASE and ScienceDirect databases were used to search for articles. Grey literature was searched from governmental and non-governmental organisation websites. Four reviewers independently screened all titles and abstracts and full-text of the articles using the Rayyan web application, based on pre-defined eligibility criteria. Results A total of 122 publications were included in the review. Most studies focused on dengue virus infection and data on Ae. aegypti. Entomological data were mainly used to determine the intervention’s effectiveness. An integrated control intervention was the most commonly employed strategy in both regions. Biological control measures, environmental management, and health education campaigns on community participation achieved more sustainable results than an intervention where only a chemical control measure was used. Challenges to implementing interventions were insufficient financial support, resources, workforce, intersectoral collaboration and legislation. Conclusions Based on the synthesised data, an integrated vector (Aedes) management focused on community participation seems to be the most effective approach to mitigate Aedes-borne infectious diseases. Maintaining the approach’s effect remains challenging as it requires multisectoral and multi-disciplinary team engagement and active community participation. Future research needs to address the barriers to program implementation and maintenance as data on this topic is lacking.

Public participation in urban planning is a contested issue in China. In this article, we look at the endogenous mechanism of institutional change, by analyzing the roles and motivations of “third-party” planning professionals in two contrasting cases: a government-led and a citizen-led participatory practice. Findings show that planners were advocates of citizen participation in heritage preservation in both cases and acted as “mediators” in the first and “activists” in the second, yet remained within the mainstream planning structure. Their motivation to serve the rights of the citizens was clear, but subordinate to the drive to conform to the professional norms of authenticity in preservation in both cases. In contrast to both the Global North where more agonistic approaches question inclusive planning and the Global South where insurgent planning finds space to maneuver, Chinese urban planning seems to proceed by taking small steps within narrow margins when it comes to citizen engagement.

Large infrastructural sectors like energy, transport, agriculture, water and wastewater or housing are increasingly under pressure to become more sustainable in face of climate change related natural hazards and accelerated social inequalities. Resilient urban water infrastructures of the future might require thae transition towards a novel socio-technical configuration: moving away from large-scale centralized treatment facilities towards more small-scale, decentralized and modular technologies developed and run by new actors, and governed by novel rules and regulations. Innovations for this transition are likely to emerge both within global networks, among the various global networks of technology experts, working in NGOs, multinational companies or investment banks, and among local operators of today’s urban water infrastructures and their users. Drawing on Sustainability Transitions and Evolutionary Economic Geography literature, the purpose of this thesis is twofold. First, it seeks to explore how established socio-technical configurations are transformed in the water sector. Second, it investigates how geography and scalar-relational processes condition these re-configuration processes in specific places. To operationalize this dual perspective on both socio-technical configurations and the geography, in which they emerge or not, a novel methodological approach is proposed that combines discourse and social network analysis as well as expert interviews: socio-technical configuration analysis (STCA). The thesis demonstrates the applicability of STCA for studying socio-technical change across space and time and discusses wider implications for the fields of sustainability transitions and economic geography more broadly.

Since the 1980s spatial inequality within countries has been increasing. This thesis focuses in three parts on how certain agglomeration advantages of cities, known as agglomeration economies, have changed and why: 1) According to Marshall (1890) agglomeration economies consist of local advantages in exchanging, respectively, products, employees, and ideas. In this chapter, the relevance of each is measured over time by gathering historical U.S. data on the coagglomeration of industries and the extent to which these buy/sell products from each other, employ similar workers, and patent similar technologies. The results show that since 1970 the local exchange of ideas has become more relevant whereas exchanging products and employees has become less relevant. These changes are influenced by the rise of computer technology, as measured by the decreasing share of routine task intensive jobs, and trade competition from low-wage countries that make industries more knowledge-intensive. Surprisingly, the decreasing transportation costs of goods is not significantly associated with the decreasing importance of input-output linkages nor with the other two agglomeration determinants. 2) The division of labour as agglomeration advantage is often attributed to Adam Smith (1776), who argued that physical proximity facilitates the specialisation of individuals as the fruits of their labour are more easily exchanged. In this chapter is argued that this proximity is more relevant for complex activities where individuals are specialised in more narrow fields and need face-to-face contact to collaborate in larger networks. Results confirm that more complex jobs, industries, patents, and publications are more strongly concentrated in larger cities. U.S. patent data shows that since 1830 the concentration of complex activities in large cities has increased over time, in particular during technological revolutions, which is in line with the observation that the expanding frontier of human knowledge requires an ever-larger division of labour and a stronger spatial concentration of human activities. 3) Cities also have advantages in developing future activities by building on current regional capabilities, so-called dynamic agglomeration economies. This aspect is particularly relevant for regional resilience, as the ability to overcome crises lies partly in the possibility of regions to develop new economic activities when others fade. Using the same patent data, it is shown that cities with a larger variety in technological activities are better able to develop new activities during the great crises in the history of the U.S.A.: the Long Depression (1873-1879), the Great Depression (1929-1934), and the Oil Crisis (1973-1975). The former and latter crisis co-occur with technological revolutions when general purpose technologies come up that revolutionise work and production processes. During these time periods advantages in reinventing regional economic structures become particularly relevant to adapt to new economic realities. All in all, this thesis offers insights why larger more innovative cities grow faster than other regions: 1, they have more knowledge-oriented agglomeration advantages; 2, they accommodate the growing division of labour of complex activities; and 3, they reinvent themselves more easily. The technological computer revolution and globalisation are instrumental to understand the recent growth in spatial inequality.

Rising temperatures, rapid urbanization and soaring demand for natural resources threaten deltas worldwide and make them vulnerable to rising seas, subsidence, droughts, floods, and salt intrusion. However, climate change projections in deltas often address climate-driven stressors in isolation and disregard parallel anthropogenic processes, leading to insufficient socio-political drive. Here, using a combination of process-based numerical models that integrate both climatic and anthropogenic environmental stressors, we project salt intrusion within the Mekong mega-Delta, in the next three decades. We assess the relative effects of various drivers and show that anthropogenic forces such as groundwater extraction-induced subsidence and riverbed level incisions due to sediment starvation can increase the salinity-affected areas by 10–27% compared to the present-day situation, while future sea level rise adds another 6–19% increase. These projections provide crucial input for adaptation policy development in the Mekong Delta and the methodology inspires future systemic studies of environmental changes in other deltas. Human activities, such as groundwater extraction and sediment starvation, are projected to add to climatic factors like sea level rise to exacerbate saline water intrusion into the Mekong Delta, Vietnam over the next 30 years, according to process-based model simulations.
