Translocal social resilience dimensions of migration as adaptation to environmental change.

There is growing recognition of the potential of migration to contribute to climate-change adaptation. Yet, there is limited evidence to what degree, under what conditions, for whom, and with which limitations this is effectively the case. We argue that this results from a lack of recognition and systematic incorporation of sociospatiality-the nested, networked, and intersectional nature of migration-as-adaptation. Our central objective is to utilize the translocal social-resilience approach to overcome these gaps, to identify processes and structures that shape the social resilience of translocal livelihood systems, and to illustrate the mechanisms behind the multiplicity of possible resilience outcomes. Translocal livelihood constellations anchored in rural Thailand as well as in domestic and international destinations of Thai migrants serve as illustrative empirical cases. Data were gathered through a multisited and mixed-methods research design. This paper highlights the role of the distinct but interlinked situations and operational logics at places of origin and destination, as well as the different positionalities and resulting vulnerabilities, roles, commitments, and practices of individuals and households with regard to resilience. Based on the empirical results, the paper distills a generalized typology of five broad categories of resilience outcomes, which explicitly considers sociospatiality. Our approach helps to grasp the complexity of migration-as-adaptation and to avoid simplistic conclusions about the benefits and costs of migration for adaptation-both of which are necessary for sound, evidence-based, migration-as-adaptation policymaking.

Dynamics and factors influencing return migration to Sub-Saharan Africa: A systematic review.

Background: Return migration, the process of migrants returning to their countries of origin, is a vital aspect of migration that has received growing attention in recent years. One area of focus in the study of return migration is understanding the motivations that drive migrants to return home. Conducting a regional literature review on the dynamics and factors influencing return migration can provide valuable insights into this complex and dynamic phenomenon. It can inform policy development, help to address economic and social issues and contribute to our understanding of migration patterns and trends in the region. Purpose: This study, therefore, aims to understand the dynamics and factors that influence return migration to Sub-Saharan Africa, a region that has experienced significant outflows of migration over the past few decades. This study provides an understanding of the drivers of and barriers to return migration and how far they resonate with factors of mobility and immobility. Methods: A two-decade systematic literature review was conducted to determine the driving factors and barriers that influence return migration to Sub-Saharan Africa (SSA). Multivariate factors of return migration were examined based on the central question: why do migrants return to their homeland? The multiple-step systematic literature search covers a broad range of factors of return migration to sub-Saharan Africa. Result: The findings indicate complex scenarios influencing decisions to return to the region, with the interplay of driving factors as well as barriers to return. Social, personal, economic, and policy factors were among the major drivers of return migration, but social and personal drivers were found to be the major motivating factors of decisions to return to SSA, compared to policy and economic issues. The observed drivers and barriers to returning migration in SSA were categorized and discussed under thematic sections considering structural, individual and policy issues. Conclusion: The study concludes that migrants' decisions to return could be determined by numerous structural factors, such as economic, political, social and environmental circumstances, both at the place of origin and at the destination. Therefore, the review could be a useful contribution to future research, governments, mobility-oriented organizations and policymakers for effective return-migration strategies.

Evolution of research in health geographics through the International Journal of Health Geographics (2002-2015).

Health geographics is a fast-developing research area. Subjects broached in scientific literature are most varied, ranging from vectorial diseases to access to healthcare, with a recent revival of themes such as the implication of health in the Smart City, or a predominantly individual-centered approach. Far beyond standard meta-analyses, the present study deliberately adopts the standpoint of questioning space in its foundations, through various authors of the International Journal of Health Geographics, a highly influential journal in that field. The idea is to find space as the common denominator in this specialized literature, as well as its relation to spatial analysis, without for all that trying to tend towards exhaustive approaches. 660 articles have being published in the journal since launch, but 359 articles were selected based on the presence of the word "Space" in either the title, or the abstract or the text over 13 years of the journal's existence. From that database, a lexical analysis (tag cloud) reveals the perception of space in literature, and shows how approaches are evolving, thus underlining that the scope of health geographics is far from narrowing.

Asymptomatic carriage of plasmodium in urban Dakar: the risk of malaria should not be underestimated.

INTRODUCTION: The objective of this study was to measure the rate of asymptomatic carriage of plasmodium in the Dakar region two years after the implementation of new strategies in clinical malaria management. METHODOLOGY: Between October and December 2008, 2952 households selected in 50 sites of Dakar area, were visited for interviews and blood sampling. Giemsa-stained thick blood smears (TBS) were performed for microscopy in asymptomatic adult women and children aged 2 to 10 years. To ensure the quality of the microscopy, we performed a polymerase chain reaction (PCR) with real time qPCR in all positive TBS by microscopy and in a sample of negative TBS and filter paper blood spots. RESULTS: The analysis has concerned 2427 women and 2231 children. The mean age of the women was 35.6 years. The mean age of the children was 5.4 years. The parasite prevalence was 2.01% (49/2427) in women and 2.15% (48/2231) in children. Parasite prevalence varied from one study site to another, ranging from 0 to 7.41%. In multivariate analysis, reporting a malaria episode in 2008 was associated with plasmodium carriage (OR = 2.57, P = 0.002) in women; in children, a malaria episode (OR = 6.19, P<0.001) and a travel out of Dakar during last 3 months (OR = 2.27, P = 0.023) were associated with plasmodium carriage. Among the positive TBS, 95.8% (93/97) were positive by plasmodium PCR. Among the negative TBS, 13.9% (41/293) were positive by PCR. In blood spots, 15.2% (76/500) were positive by PCR. We estimated at 16.5% the parasite prevalence if PCR were performed in 4658 TBS. CONCLUSION: Parasite prevalence in Dakar area seemed to be higher than the rate found by microscopy. PCR may be the best tool for measuring plasmodium prevalence in the context of low transmission. Environmental conditions play a major role in the heterogeneity of parasite prevalence within sites.
