How are electricity generation effective on carbon neutrality in the global south? Evidence from sectoral CO2 emissions by daily data

In light of the efforts to ensure carbon neutrality by combating climate-related problems, the study investigates the effectiveness of electricity generation (EG) from the main renewable sources (hydro-HEG, solar-SEG, and wind-WEG). In this context, the study examines the countries of the Global South (i.e., Brazil, China, and India), considers EG at a disaggregated level and sectoral CO2 emissions, applies nonlinear methods, and uses daily data between January 2, 2019 and December 31, 2022. The results demonstrate that (i) disaggregated EG sources have a stronger (weaker) time and frequency dependency on sectoral CO2 emissions in China (Brazil and India); (ii) HEG has a stimulating impact on sectoral CO2 emissions in all countries; (iii) SEG has an increasing impact on sectoral CO2 emissions in Brazil and China, while it provides a decrease in sectoral CO2 emissions in India; (iv) WEG upsurges sectoral CO2 emissions in China, while it achieves a CO2 reduction in Brazil and India; (v) disaggregated level EG has a causal impact on sectoral CO2 emissions across all quantiles except some lower, middle, and higher quantiles. The study adds scientific value to existing knowledge by analyzing for the first time which EG sources are effective in reducing daily CO2 emissions in the Global South. Based on the outcomes, the study demonstrates that WEG is the best EG source for Brazil, that SEG and WEG are optimal EG sources for India, and that China cannot benefit from the EG sources considered. In this way, the study provides fresh insights for the countries of the Global South and underlines the crucial role of renewable EG in ensuring carbon neutrality.

Adaptation of solar energy in the Global South: Prospects, challenges and opportunities

The Global South comprising economically disadvantaged regions of the world face various challenges such as limited access to electricity, clean water, industrialization, and food security. Solar energy, as a sustainable and abundant resource, holds great potential to address these challenges. Despite its immense potential, the Global South encounters hurdles related to technology adoption, infrastructure, and financial constraints. This review examines the history, classifications, global statistics, merits, and demerits of solar technology in the Global South. Furthermore, it delves into various applications of solar energy, including extreme environments, residential electricity generation, transportation, and industrial usage in this region. This study concludes by providing new insighths and highlighting the significant role solar energy can play in shaping the future of the Global South if challenges are adequately addressed, and opportunities are embraced.

A critical systematic review and meta-analyses of risk factors for fertility problems in a globalized world

Globally, fertility awareness efforts include well-established risk factors for fertility problems. Risks disproportionately affecting women in the Global South, however, are neglected. To address this gap, we conducted a systematic review and meta-analyses of relevant risk factors to examine the association between risk factors and fertility problems. MEDLINE, Embase, Cochrane Library, regional databases and key organizational websites were used. Three authors screened and extracted data independently. Studies assessing exposure to risk (clinical, community-based samples) were included, and studies without control groups were excluded. Outcome of interest was fertility problems, e.g. inability to achieve pregnancy, live birth, neonatal death depending on study. The Newcastle-Ottawa Scale was used to assess study quality. A total of 3843 studies were identified, and 62 were included (58 in meta-analyses; n = 111,977). Results revealed the following: a ninefold risk of inability to become pregnant in genital tuberculosis (OR 8.91, 95% CI 1.89 to 42.12); an almost threefold risk in human immunodeficiency virus (OR 2.93, 95% CI 1.95 to 4.42) and bacterial vaginosis (OR 2.81, 95% CI 1.85 to 4.27); a twofold risk of tubal-factor infertility in female genital mutilation/cutting-Type II/III (OR 2.06, 95% CI 1.03 to 4.15); and postnatal mortality in consanguinity (stillbirth, OR 1.28, 95% CI 1.04 to 1.57; neonatal death, OR 1.57, 95% CI 1.22 to 2.02). It seems that risk factors affected reproductive processes through multiple pathways. Health promotion encompassing relevant health indicators could enhance prevention and early detection of fertility problems in the Global South and disproportionately affected populations. The multifactorial risk profile reinforces the need to place fertility within global health initiatives.

Experiences of loneliness in lower- and middle-income countries: A systematic review of qualitative studies

Loneliness is understood as a subjective experience resulting from unmet social relationship expectations. As most loneliness research has been conducted in higher-income-countries, there is limited understanding of loneliness in relation to diverse cultural, economic, and socio-political factors. To address this gap, the present review systematically synthesises existing qualitative studies on the experience of loneliness and social relationship expectations in lower- and middle-income countries (LMICs). Between June and July 2022, six online databases (Embase, Ovid Medline, APA PsycINFO, Global Health, Web of Science, Google Scholar) were searched for peer-reviewed studies from LMICs on loneliness using qualitative methods. There were no restrictions on publication date, language, or study setting. Studies that solely focused on social isolation or were conducted with children (<16 years) were excluded. Risk of bias was assessed with the Critical Appraisal Skills Programme. After deduplication, a total of 7866 records were identified and screened for inclusion, resulting in 24 studies published between 2002 and 2022. The included studies represent data from 728 participants in 15 countries across West Africa (Ghana, Nigeria, Niger, Mali), East Africa (Uganda, Kenya), North Africa (Egypt), West Asia (Iran), South Asia (India, Pakistan, Sri Lanka) and Southeast Asia (Myanmar, Cambodia, Indonesia, Philippines). Data were analysed combining inductive and deductive coding, summarised using narrative synthesis, and examined by geographical region. Common features of loneliness included rejection, overthinking, and pain. Loneliness was related to depression across regions. Whereas loneliness tended to be distinguished from social isolation in studies from Africa, it tended to be related with being alone in studies from Asia. Poverty and stigma were common barriers to fulfilling social relationship expectations. This review illustrates how loneliness and expectations are contextually embedded, with some expectations possibly being specific to a certain culture or life stage, having implications for assessment of and interventions for loneliness worldwide.

Effects of microfinance and small loans centre on poverty reduction in Wa West District, Ghana

Poverty, a pervasive and consequential global issue, has garnered significant attention due to its wide-reaching prevalence and profound implications. Various strategies, including microfinance, have been implemented to tackle this pressing concern. One such strategy is the Microfinance and Small Loans Centre (MASLOC) in Ghana, which aims to reduce poverty. However, despite its potential, MASLOC's role in poverty reduction has yet to be thoroughly examined, leading to inconclusive findings, and necessitating this study. A single case study design addressed this research gap and provided valuable insights. A comprehensive dataset was compiled through interviews and observations involving 40 MASLOC beneficiaries and officials. Thematic analysis was utilized to dissect the collected data, revealing noteworthy patterns and trends. The study's outcomes shed light on MASLOC's effectiveness in mitigating poverty. Specifically, it was found that MASLOC played a pivotal role in poverty reduction by bolstering income levels, amplifying consumption patterns, facilitating access to fundamental necessities, and enabling the accumulation of valuable assets. Nevertheless, the analysis also highlighted specific challenges. Issues related to loan repayment and staffing emerged as constraints within the MASLOC framework. In essence, the study established that MASLOC contributes to the overarching goal of poverty reduction. The findings are helpful because fostering a positive attitude towards loan repayment is crucial, and this endeavour should be complemented by the strategic recruitment of competent staff members who can effectively navigate the intricacies of the scheme to ensure the sustainability of MASLOC. What sets this study apart is its innovative exploration of the impact of MASLOC on poverty-a primarily overlooked facet. By delving into this uncharted territory, the study enriches the ongoing discourse surrounding government microfinance schemes' influence on its beneficiaries. This research contributes not only to the academic realm but also to the practical realm, as it offers actionable insights for policymakers in poverty reduction.

Monkeypox vaccination in the global south: Fighting a war without a weapon

Background

The Mpox outbreak awakened countries worldwide to renew efforts in epidemiological surveillance and vaccination of susceptible populations. In terms of Mpox vaccination, various challenges exist in the global south, which impede adequate vaccine coverage, especially in Africa. This paper reviewed the situation of Mpox vaccination in the global south and potential ameliorative approaches.

Methods

A review of online literature from PubMed and Google Scholar concerning Mpox vaccination in countries belonging to the 'global south' category was done between August and September, 2022. The major focus areas included inequity in global vaccine distribution, challenges impeding vaccine coverage in the global south, and potential strategies for bridging the gap in vaccine equity. The papers that met the inclusion criteria were collated and narratively discussed.

Results

Our analysis revealed that, while the high-income countries secured large supplies of the Mpox vaccines, the low- and middle-income countries were unable to independently access substantial quantities of the vaccine and had to rely on vaccine donations from high-income countries, as was the case during the COVID-19 pandemic. The challenges in the global south particularly revolved around inadequate vaccine production capacity due to lack of qualified personnel and specialized infrastructure for full vaccine development and manufacturing, limited cold chain equipment for vaccine distribution, and consistent vaccine hesitancy.

Conclusion

To tackle the trend of vaccine inequity in the global south, African governments and international stakeholders must invest properly in adequate production and dissemination of Mpox vaccines in low- and middle-income countries.

The Sexual and Reproductive Health of Adolescents with Cerebral Palsy in Rural Bangladesh: A Qualitative Analysis

Adolescents with disability in the Global South have unique sexual and reproductive health (SHR) experiences and needs; however, they are rarely included in SRH discourse. This qualitative study, conducted in rural Bangladesh, used semi-structured interviews to understand how adolescents with cerebral palsy (CP) experience their SRH. Participants were recruited from the Bangladesh Cerebral Palsy Register and included 24 adolescents with CP (n = 12 female; n = 12 male) and 76 parents (n = 56 mothers, n = 17 fathers, n = 3 other relatives). Data were analyzed using reflexive thematic analysis. Findings highlighted heterogeneity among adolescents with CP including differences for adolescent men versus women. For some adolescent men with CP, sexual maturity was viewed as bringing new opportunities, whereas for other men, adolescence affirmed exclusions and some transgressed sociocultural norms as they struggled to navigate their pubescent body alongside new privacy requirements. For adolescent women with CP, sexual maturity was associated with new domestic responsibilities, silence and secrecy regarding menstruation, and increased vulnerability to sexual violence and abuse. Adolescent men and women with CP spoke about marriage as something "everybody wants," however, was deemed "impossible" for those with more impairment-related support needs. Both adolescent men and women with CP lacked access to SRH information and support. Mothers positioned providing care to their adolescent child with CP after puberty as "shameful." Our findings suggest that disability, health, and education services in rural Bangladesh need to adopt a life-course approach that incorporates the SRH of adolescents with CP. We recommend the provision of SRH education that addresses the physical, cognitive, and social needs of adolescents with CP.

The incidence of non-affective psychotic disorders in low and middle-income countries: a systematic review and meta-analysis

PURPOSE

Global understanding of the epidemiological landscape of non-affective psychotic disorders (NAPD) is predominantly based on studies from high-income countries. We sought to systematically review and meta-analyse all incidence studies conducted in low and middle-income countries (LMICs).

METHODS

We systematically searched four databases using terms for NAPD, incidence and LMICs. Citations were eligible for inclusion if: published between 1 January 1960 and 31 May 2022; wholly or partially conducted in an LMIC, and; containing data on NAPD incidence in the general adult population. Two independent raters assessed study quality according to previously published criteria. We conducted a narrative synthesis and random-effects meta-analyses where sufficient studies were available (N ≥ 5).

RESULTS

We retrieved 11 421 records, of which 23 citations met inclusion criteria from 18 unique studies across 19 settings in 10 LMICs. Median study quality was 4 out of 7 (interquartile range: 3-6). The crude incidence of NAPD varied around 4.2 times, from 10.0 per 100,000 person-years (95% confidence interval [CI] 8.7-11.4) in Brazil to 42.0 (95%CI 32.2-54.8) in India, with marked heterogeneity in methodologies and rates. Our 60-year review highlights the dearth of robust evidence on the incidence of psychotic disorders in LMICs.

CONCLUSION

Without reliable, contemporary estimates of this fundamental cornerstone of population health, it is impossible to understand the true burden, distribution or causes of psychotic disorders in over 87% of the world's population. A new, more equitable global mental health evidence base for NAPD is now urgently required.

Zooplankton exposure to microplastic contamination in a estuarine plume-influenced region, in Northeast Brazil

This work describes the spatio-temporal distribution of suspected plastic and microplastic (MP) particles in estuarine plumes and analyzes the microplastic/zooplankton ratio. Subsurface hauls with a conical-cylindrical net were deployed in the coastal area of Tamandare (Pernambuco, Brazil), covering the plume of two rivers and a bay adjacent to coral reefs. A total of 2079 suspected plastic particles were detected, mostly fibers and fragments (>60%). Organic matter digestion was made using a 30% hydrogen peroxide solution, of which approximately 50% of suspected particles were validated as MPs. The average MP abundance was significantly higher during the high rainfall season (53.8 ± 89.6 and 18.8 ± 32.3 particles/m³, respectively), with higher values registered in the plume area (108.9 ± 158.5 and 44.6 ± 55.5 particles/m³). Polymer identification using FT-IR confirmed that suspected particles were mainly polypropylene, polyamide, and polyurethane. These results confirm the hypothesis of a temporal transport variation of MPs from the river to the coastal environments, particularly since the plume influences debris input. Eleven animal phyla were identified, and the subclass Copepoda was predominant (90%), particularly the nauplius stage (70%). Over 70% of verified MPs range between 20 and 2000 μm, equivalent to the most common size of zooplanktonic organisms. Results support that coastal areas near estuarine plumes are exposed to microplastic contamination, affecting species dependent on zooplankton in marine coastal food webs.

Mind the gap: The challenges of sustainable forensic science service provision

Recent worldwide humanitarian and security efforts reflect the growth of forensic science as a global practice supporting peace, prosperity, and justice. While the dominance of the Global North in published research and public attention may suggest that this practice is universally well-developed, many Global South jurisdictions are at a stark disadvantage in resourcing and technological capabilities. Continued development of forensic science as an international endeavour requires a narrowing of inequalities between jurisdictions, in line with the United Nations Sustainable Development Goals. Here we propose a framework of principles for the sustainable provision of transparent, high-quality forensic services meeting jurisdictional needs and limitations. We illustrate how this concept of 'frugal forensics' can be applied in the context of latent fingermark detection in two Global South jurisdictions, and how quality assurance frameworks can be developed to support this service.

A global review of the temporal and spatial patterns of DDT and dieldrin monitoring in raptors

Concentrations of organochlorine pesticides have been extensively monitored in birds, particularly from higher trophic guilds such as raptors. While monitoring of raptors has been ongoing for decades, patterns from monitoring activities have never been summarised on a global scale. In this study, we undertake a review to better describe the monitoring of two widespread organochlorine pesticides monitored globally in raptors, DDT and dieldrin. We provide a historical retrospective on the monitoring effort of a global environmental issue. Sampling was heavily biased geographically to the global north, with more than 90 % of studies conducted in this socio-geographic region, most from Europe and North America. Although monitoring occurred from at least 114 species, most samples came from relatively few species, with three species (Eurasian Sparrowhawk Accipiter nisus, Bald Eagle Haliaeetus leucocephalus, and Peregrine Falcon Falco peregrinus) comprising 50 % of samples. The types of raptors sampled have changed over time, with avian and mammal specialists dominating samples until the 1970s, but more diverse dietary guilds monitored in later decades, and greater proportions of samples coming from generalist species. The three most sampled tissues (egg, liver, and plasma) comprised 84 % of all samples. Eggs were the earliest tissue examined and the only tissue sampled in all decades. The geographical bias in monitoring effort and relatively narrow species focus, suggests that patterns in these pesticides are unlikely to be fully representative of all global environments occupied by raptors. While DDT has been banned throughout most of the global north, it remains in use in the global south, yet monitoring effort in the south, does not match that of the north. While monitoring remains prevalent in the global north, contemporary monitoring is limited in the global south with less than 10 % of raptors sampled in Asia, Africa, and South America, over the last 3 decades.

Should they stay or should they go? A case study on international students in Germany

International students are conceived as essential contributors to the development of their countries of origin after they finished their studies abroad. Political decision-makers of the countries of origin therefore take measures that students will eventually return to their home countries and bring back their gained knowledge and consequently contribute to development back home. However, is a return always the best way to contribute to development in the country of origin or can international graduates contribute equally from abroad or through their high mobility between different countries? This article aims to address this question on the basis of an intensive three years mixed-methods-based investigation in six countries - Germany as country of study and Colombia, Georgia, Ghana, Indonesia and Israel/Palestinian territories as countries of origin. We investigated a specific German scholarship program, which gives scholarships to international students from the Global South to study in Germany. Although a return to the country of origin is a precondition for the scholarship, our study indicates that not only return migration, but also remains and circular migration can create beneficial circumstances that former students practice diverse development-related functions and therefore contribute to the development in their country of origin in a specific way. Here, it is important to recognize that scholarship programs do not only offer the opportunity to fund studying abroad, but they can be also designed for the needs of scholars during, before and after their studies, which would also benefit their developmental contributions.

Women's participation in the prevention and control of dengue using environmental methods in the global south: a qualitative meta-synthesis

Background

Dengue, a mosquito-borne viral disease, causes significant mortality and morbidity in low- to middle-income countries. A body of research indicates that women can be effective in implementing vector borne disease control, but they still face inequitable opportunities for participation, leadership and decision-making in the execution of dengue prevention and vector control programmes. Yet implementing informal environmental management practices to prevent mosquito vector breeding forms part of their domestic household responsibilities. Understanding the enablers and barriers to women’s equitable roles with men in formal and informal disease prevention, and the benefits of their participation could help to increase their role and may be a contributing factor to reducing disease rates. The objective of this qualitative meta-synthesis was to synthesise evidence about women’s roles in dengue prevention and control in the global south and generate insights around the barriers, enablers, and benefits.

Methods

Eight databases were searched from inception to 7^th December 2020. One investigator independently reviewed all titles and abstracts for relevant articles. Grey literature was searched using 34 websites of global health and international development organisations.

Results

A total of 18 articles representing qualitative research or the qualitative component of mixed methods studies from Latin American and Caribbean (n = 8), Asia (n = 9), and one international review were included in the meta-synthesis. Relevant scholarship from Africa was lacking. This meta-synthesis revealed five unique themes surrounding women’s participation, seven categories of barriers, six of enablers, four health, well-being and social benefits for individuals, and four for communities .

Conclusion

An analysis of the results confirmed that women’s participation in dengue prevention was not gender equitable, gender sensitive nor transformative although women are the primary human resource for household and community-based prevention. Women demonstrated specific qualities aiding successful implementation. Corrective action is urgently needed to shift unhelpful gender norms, and empower women into leadership and decision-making roles.

Childhood blood lead levels and environmental risk factors in Madagascar

One-third of children globally have blood lead levels (BLLs) exceeding the (former) US CDC reference value of 5 µg/dL; this value may be as high as one-half for children in low- and middle-income countries (LMICs). Lead exposure occurs through a variety of routes (e.g., water, dust, air), and in LMICs specifically, informal economies (e.g., battery recycling) can drive lead exposures due, in part, to absent regulation. Previous work by our team identified a ubiquitous source of lead (Pb), in the form of Pb-containing components used in manually operated pumps, in Toamasina, Madagascar. Characterization of BLLs of children exposed to this drinking water, and identification of additional exposure routes were needed. BLLs were measured for 362 children (aged 6 months to 6 years) in parallel with surveying to assess 14 risk factors related to demographics/socioeconomics, diet, use of pitcher pumps, and parental occupations. BLL data were also compared against a recent meta-review of BLLs for LMICs. Median childhood BLL (7.1 µg/dL) was consistent with those of other Sub-Saharan African LMICs (6.8 µg/dL) and generally higher than LMICs in other continents. Risk factors significantly associated (p < 0.05, univariate logistic regression) with elevated BLL (at ≥ 5 µg/dL) included male gender, living near a railway or major roadway (owing potentially to legacy lead pollution), having lower-cost flooring, daily consumption of foods (beans, vegetables, rice) commonly cooked in recycled aluminum pots (a previously identified lead source for this community), and a maternal occupation (laundry-person) associated with lower socioeconomic status (SES). Findings were similar at the ≥ 10 µg/dL BLL status. Our methods and findings may be appropriate in identifying and reducing lead exposures for children in other urbanizing cities, particularly in Sub-Saharan Africa, where lead exposure routes are complex and varied owing to informal economics and substantial legacy pollution.

Reducing disease and death from Artisanal and Small-Scale Mining (ASM) - the urgent need for responsible mining in the context of growing global demand for minerals and metals for climate change mitigation

Artisanal and small-scale mining (ASM) takes place under extreme conditions with a lack of occupational health and safety. As the demand for metals is increasing due in part to their extensive use in 'green technologies' for climate change mitigation, the negative environmental and occupational consequences of mining practices are disproportionately felt in low- and middle-income countries. The Collegium Ramazzini statement on ASM presents updated information on its neglected health hazards that include multiple toxic hazards, most notably mercury, lead, cyanide, arsenic, cadmium, and cobalt, as well as physical hazards, most notably airborne dust and noise, and the high risk of infectious diseases. These hazards affect both miners and mining communities as working and living spaces are rarely separated. The impact on children and women is often severe, including hazardous exposures during the child-bearing age and pregnancies, and the risk of child labor. We suggest strategies for the mitigation of these hazards and classify those according to primordial, primary, secondary, and tertiary prevention. Further, we identify knowledge gaps and issue recommendations for international, national, and local governments, metal purchasers, and employers are given. With this statement, the Collegium Ramazzini calls for the extension of efforts to minimize all hazards that confront ASM miners and their families.

Ethical Considerations from Child-Robot Interactions in Under-Resourced Communities

Recent advancements in socially assistive robotics (SAR) have shown a significant potential of using social robotics to achieve increasing cognitive and affective outcomes in education. However, the deployments of SAR technologies also bring ethical challenges in tandem, to the fore, especially in under-resourced contexts. While previous research has highlighted various ethical challenges that arise in SAR deployment in real-world settings, most of the research has been centered in resource-rich contexts, mainly in developed countries in the 'Global North,' and the work specifically in the educational setting is limited. This research aims to evaluate and reflect upon the potential ethical and pedagogical challenges of deploying a social robot in an under-resourced context. We base our findings on a 5-week in-the-wild user study conducted with 12 kindergarten students at an under-resourced community school in New Delhi, India. We used interaction analysis with the context of learning, education, and ethics to analyze the user study through video recordings. Our findings highlighted four primary ethical considerations that should be taken into account while deploying social robotics technologies in educational settings; (1) language and accent as barriers in pedagogy, (2) effect of malfunctioning, (un)intended harms, (3) trust and deception, and (4) ecological viability of innovation. Overall, our paper argues for assessing the ethical and pedagogical constraints and bridging the gap between non-existent literature from such a context to evaluate better the potential use of such technologies in under-resourced contexts.

The emergence of recreational cycling in Hanoi during the Covid-19 pandemic

OBJECTIVES

This study examined recreational cycling in Hanoi, Vietnam, with a particular focus on changes brought about by the Covid-19 pandemic. The research questions were: (1) Has recreational cycling increased during the Covid-19 pandemic?; (2) If so, what factors have led to the increase?; and (3) What are some of the typical traits and behaviors of recreational cyclists?

METHOD

Face-to-face surveys of 356 recreational cyclists were carried out in March-April 2021 in four areas of inner Hanoi. The survey data were modelled through two binary and one ordinal logit regression.

RESULTS

Recreational cycling has become much more popular in Hanoi during the Covid-19 pandemic, with early morning being the preferred time for this activity (to avoid heavy traffic). A quarter of the participants had starting cycling recreationally since the first lockdown in April 2020, and about three quarters reported having noticed an increase in cycling activity around them. Nearly half of the participants cycled regularly (more than four times per week). The groups that were most likely to have taken up cycling for recreations during the pandemic included men, those living with children in the home, and those not working or studying. Age and income were not significant. People have been embracing cycling as a way to maintain or increase physical activity levels, and to safely socialize at the time when social gatherings are limited, walking is prohibited in some zones, and social distancing rules apply everywhere.

CONCLUSION

To sustain the growth in recreational cycling and widen the time-window for this activity while ensuring everyone's safety, Hanoi's planning and public health sectors should join forces to adopt a combination of 'hard' and 'soft' measures. The authors recommend creating multi-use paths for micromobility modes, launching a public bikesharing scheme, regulating motorised modes, and social marketing that promotes recreational cycling as trendy.

Transport preferences and dilemmas in the post-lockdown (COVID-19) period: Findings from a qualitative study of young commuters in Dhaka, Bangladesh

At the start of the pandemic in early 2020, many cities went to complete or partial lockdown to minimize the mass transmission of COVID-19. Consequently, personal travel patterns have changed throughout the world. This study explores the transport mode preferences and associated dilemmas that commuters face in Dhaka, Bangladesh, in the post-lockdown period. We conducted in-depth semi-structured interviews of 20 young commuters residing in Dhaka. We followed a deductive reasoning approach, and the transcriptions were analyzed following thematic analysis. Findings suggest that despite the perceived high risk of COVID-19 transmission in certain modes, all commuters don't have the ease and flexibility to switch to their preferred safer mode, with commuters trading-off between health risk, affordability and availability of suitable modes, along with other challenges. However, the country's sustainable goals can still be achieved if proper actions, such as removing the challenges commuters face while switching to a sustainable and safe mode during COVID-19 are taken.

Why cultural ecosystem services matter most: Exploring the pathways linking greenspaces and mental health in a low-income country

Exposure to urban greenspaces promotes a variety of mental health benefits. However, much of the evidence for these benefits is biased towards high-income countries. In contrast, urban areas in low-income settings that have the highest rates of urbanisation remain understudied. Given the increasing burden of mental ill-health associated with urbanisation in low- and middle-income countries (LMICs), there is a clear need to better understand the role urban greenspaces play in mitigating mental ill-health. Here we use a novel combination of research methods (participatory video, focus groups and the Q-methodology) in a rapidly urbanising low-income city (Kathmandu, Nepal). We explored residents' perspectives on ecosystem services, and the pathways linking greenspaces to mental health. Residents indicated that greenspaces are linked to mental health through pathways such as reducing harm (exposure to air pollution and heat), restoring capacities (attention restoration and stress reduction), building capacities (encouraging physical activity, fostering social cohesion and child development) and causing harm (human - wildlife conflicts, gender discrimination). It is likely that a combination of such pathways triggers mental health impacts. Of all ecosystem services, cultural services such as providing settings for recreation, or intellectual or mental interactions with greenspaces involving analytical, symbolic, spiritual or religious activities were most preferred. Our findings emphasise that cultural ecosystem services provide a fundamental basic need which all people, including low-income residents, depend on to participate meaningfully in society. Urban greenspaces therefore play a pivotal role in reducing the burden of mental ill-health for low-income residents in LMICs. Greater efforts to increase the quantity, quality and accessibility of greenspaces may help to address current health inequalities in LMICs.

Work-from/at/for-home: CoVID-19 and the future of work - A critical review

The Covid19 pandemic has led to speculation about the place of offices in the future world of work - while working-from-home was initially mandated by employers (and governments), recent research has reported that the practice has gained popularity among employees. However, most such research is based on experiences of workers in the Global North. The article challenges the conflation of the Global North with global and shifts the focus from 'flexible working' and 'work-life balance' to issues of access to work infrastructures, including space, internet, and care. It draws upon existing scholarship on home-based work and precarious work, especially gig work, to outlines ways to analyse the implications of working-from-home in diverse settings. Illustrated with the story of Prachi, a young e-commerce worker in Delhi, the article offers work-from/at/for-home as a wider framework that accounts for inequalities in labour and life conditions of workers around the world.

Refugees in Brazil: An investigation of Syrian refugees' psychological experiences

Although there is a strong body of literature on the psychosocial distress of refugees from Global South to Global North, there is limited literature on refugees who migrate from Global South (i.e., Syria) to Global South (i.e., Brazil). The present study aims to investigate Syrian refugees in Brazil. Participants were 202 Syrians. Most respondents were men (62.9%), with an average age of 35.9 years old (SD = 11.13). Results suggest an effect of positive ethnic identity in psychological and physical distress, who also perceive more discrimination than individuals who negatively identify with their ethnicity. Structural equation model suggests the fit of the proposed mediation model. Our findings add to the much-needed line of investigations examining Syrian refugees settling in Brazil.

A mixed methods study examining neighborhood disadvantage and childhood behavior problems in Montevideo, Uruguay

BACKGROUND

Neighborhood disadvantage (ND) is a risk factor for child behavior problems (CBPs), but is understudied outside the United States and Europe. Our mixed methods study aims to (1) create a culturally meaningful measure of ND, (2) test cross-sectional associations between ND and CBPs and (3) qualitatively explore life in the neighborhoods of families participating in the Salud Ambiental Montevideo (SAM) study.

METHODS

The quantitative study (Study 1) comprised 272, ~7-year-old children with geolocation and complete data on twelve behavioral outcomes (Conner's Teachers Rating Scale - Revised Short Form: CTRS-R:S and Behavioral Rating Inventory of Executive Functioning: BRIEF). A ND factor was created at the census segment level (1,055 segments) with 19 potential indicators of ND downloaded from the Municipality of Montevideo Geographic Services. Children were assigned ND scores based on the location of their household within a census segment. Multilevel models tested associations between ND and all CBP scales, controlling for confounders at the individual level. The qualitative study (Study 2) comprised 10 SAM caregivers. Photovoice alongside semi-structured interviews in Spanish were used to foster conversations about neighborhood quality, activities, and raising children. Thematic analysis with inductive coding was used to summarize qualitative study findings.

RESULTS

The ND factor consisted of 12 census-based indicators related to education, employment, ethnicity, housing quality, and age characteristics, but unrelated to home ownership and some ethnicity variables. In multivariable models, ND was associated with greater conduct problems (β = 1.37, p < .05), poor shifting (β = 1.56, p < .01) and emotional control problems (β = 2.36, p < .001). Photovoice and semi-structured interviews yielded four themes: physical disorder, recreation, safety and crime, and community resources. Residents discussed improving waste management and transportation, updating playgrounds, and ensuring neighborhood safety.

CONCLUSIONS

ND in Montevideo comprised a unique set of census indicators. ND was primarily related to behavioral regulation problems. Hypothesized pathways whereby ND affects CBPs are discussed.

Signaling Southern sustainability: When do actors use private or public regulatory authority to market tropical commodities?

The private regulation of agri-food value chains through sustainability standards has proliferated in recent decades, promising producers to differentiate themselves and gain preferential market access. However, in a number of producing countries, laws exist that mirror and go beyond what private labels demand. These countries have two options for placing their sustainable products in the market: signal their national system's equivalence to private schemes, or utilize the existing regulatory framework as favorable preconditions for widespread certification. In framing this choice as a collective reputation challenge, this study analyzes under which conditions states and parastatal actors opt for either approach, provides evidence of the strategies used, and draws conclusions on their respective success and on-the-ground outcomes. Using an in-depth comparative case study of the coffee sectors of Costa Rica and Colombia, the study finds that the divergence in institutional strategies can be explained by three factors: sector-specific institutional capacities; a country's place in the commodity marketplace, which determines the expected added pay-off of certification; and a country's overall international image.

Debates on Global Sociology: 'Unity and Diversity' of Interpretations

This paper critically looks at the ways in which 'global sociology' has been debated and conceived in the past decades. It provides an historical overview of various proposals and ideas and the institutional contexts within which they are put forward and criticized. Two different periods are distinguished. Until the early twenty-first century, on the one hand, criticism of the 'ethnocentrism of the West' was often supported by ideas and pleas for an 'indigenization' of sociological knowledge. A commitment to the unity of science and to its universalist aspirations remained strong, however. In the course of the twenty-first century, on the other hand, criticism of the 'northern dominance' in sociology has become much stronger. Instead of a 'multicultural' understanding of global sociology, a 'critical' sociology that contributes to 'global justice' is now often advocated. Based on this historical overview, it is suggested that global sociology might contribute to more self-reflexivity within the discipline. It helps us to see how different contexts reverberate into the ways in which sociology itself is imagined in this world and provides an analysis of the debates for a better understanding of the challenges which sociology currently faces.

Regional cooperation is essential to combatting health emergencies in the Global South

Since COVID-19 was first discovered, it exploded into a pandemic resulting in devastating effects on human lives and a global recession. While there have been discussions that COVID-19 will accelerate the 'end of globalization and multilateralism', we have already seen the high costs of non-cooperation in responding to the virus resulting in sub-optimal use of resources, rapid spread of the virus between countries, and, ultimately, significant loss of life. In spite of their favorable demographic structures and relatively young populations, countries in the Global South are still harshly affected in both epidemiological and economic terms. Nations must find innovative ways to address health concerns and regional bodies are possible mechanisms for facilitating international cooperation on health. We delineate how regional organizations can support how countries address health threats namely by serving as a bridge between the global and national policy levels; strengthening disease surveillance; mobilizing supply chains and facilitating trade; supporting the production and procurement of medicines and supplies; and coordinating policies and work with other actors. We finalize by arguing that mechanisms for regional cooperation must be strengthened themselves in order to effectively contribute to positive health outcomes within member states.

Universities and social innovation for global sustainable development as seen from the south

Potential contributions of universities to social innovation are explored with special attention to Southern countries. The normative guide is the notion of Sustainable Human Development understood as stressing the agency of least-advantaged sectors. The main challenges stem from decreasing sustainability and increasing inequality. Their impacts are highly dependent on how the tension between economic growth and environmental protection is managed. Improving actual perspectives demands harnessing advanced knowledge to foster inclusive and frugal innovation. For this to occur, universities need to be main actors. The context in which they act is analyzed with reference to the National Systems of Innovation conceptualization. Possible evolutions of universities as agents of social innovation are discussed with the aid of the Multi-Level Perspective. The importance of the Southern experience of innovating in scarcity conditions is highlighted and illustrated with the specific experience of a Latin American university. The cooperation of universities with weak social actors in ways that involve advanced knowledge appears as a key theoretical issue and as a difficult practical problem for the effective engagement of universities in social innovation. The diverse issues that such engagement needs to integrate conform an ambitious research program, of which the paper aims at giving a first glimpse.

The COVID-19 pandemic: local to global implications as perceived by urban ecologists

The global COVID-19 pandemic is affecting everyone, but in many different ways, stimulating contrasting reactions and responses: opportunities for some, difficulties for many. A simple survey of how individual workers in urban ecology have been coping with COVID-19 constraints found divergent responses to COVID-19 on people’s activities, both within countries and between continents. Many academics felt frustrated at being unable to do fieldwork, but several saw opportunities to change ways of working and review their engagement with the natural world. Some engaging with social groups found new ways of sharing ideas and developing aspirations without face-to-face contact. Practitioners creating and managing urban greenspaces had to devise ways to work and travel while maintaining social distancing. Many feared severe funding impacts from changed local government priorities. Around the world, the COVID-19 pandemic has amplified issues, such as environmental injustice, disaster preparation and food security, that have been endemic in most countries across the global south in modern times. However, developing and sustaining the strong community spirit shown in many places will speed economic recovery and make cities more resilient against future geophysical and people-made disasters. Significantly, top-down responses and one-size-fits-all solutions, however good the modelling on which they are based, are unlikely to succeed without the insights that local knowledge and community understanding can bring. We all will have to look at disaster preparation in a more comprehensive, caring and consistent way in future.

Cash water expenditures are associated with household water insecurity, food insecurity, and perceived stress in study sites across 20 low- and middle-income countries

Billions of people globally, living with various degrees of water insecurity, obtain their household and drinking water from diverse sources that can absorb a disproportionate amount of a household's income. In theory, there are income and expenditure thresholds associated with effective mitigation of household water insecurity, but there is little empirical research about these mechanisms and thresholds in low- and middle-income settings. This study used data from 3655 households from 23 water-insecure sites in 20 countries to explore the relationship between cash water expenditures (measured as a Z-score, percent of income, and Z-score of percent of income) and a household water insecurity score, and whether income moderated that relationship. We also assessed whether water expenditures moderated the relationships between water insecurity and both food insecurity and perceived stress. Using tobit mixed effects regression models, we observed a positive association between multiple measures of water expenditures and a household water insecurity score, controlling for demographic characteristics and accounting for clustering within neighborhoods and study sites. The positive relationships between water expenditures and water insecurity persisted even when adjusted for income, while income was independently negatively associated with water insecurity. Water expenditures were also positively associated with food insecurity and perceived stress. These results underscore the complex relationships between water insecurity, food insecurity, and perceived stress and suggest that water infrastructure interventions that increase water costs to households without anti-poverty and income generation interventions will likely exacerbate experiences of household water insecurity, especially for the lowest-income households.

What is the meaning of urban liveability for a city in a low-to-middle-income country? Contextualising liveability for Bangkok, Thailand

BACKGROUND

Creating 'liveable' cities has become a priority for various sectors, including those tasked with improving population health and reducing inequities. Two-thirds of the world's population will live in cities by 2050, with the most rapid urbanisation in low- and middle-income countries (LMIC). However, there is limited guidance about what constitutes a liveable city from a LMIC perspective, with most of the evidence relating to high-income countries, such as Australia. Existing liveability frameworks include features such as public transport, affordable housing, and public open space; however, these frameworks may not capture all of the liveability considerations for cities in LMIC contexts.

OBJECTIVES

This case study formed a multi-sectoral partnership between academics, policymakers (Bangkok Metropolitan Administration, Victorian (Australia) Department of Health and Human Services), and a non-government organisation (UN Global Compact - Cities Programme). This study aimed to: 1) conceptualise and prioritise components of urban liveability within the Bangkok, Thailand context; 2) identify alignment to or divergence from other existing liveability tools; and 3) identify potential indicators and data sources for use within a Pilot Bangkok Liveability Framework.

METHODS

The Urban Liveability Workshop involving technical leaders from the Bangkok Metropolitan Administration and a rapid review of liveability literature informed the conceptualisation of liveability for Bangkok. The Bangkok Metropolitan Administration Working Group and key informants in Bangkok provided input into the liveability framework. Indicators identified for Bangkok were mapped onto existing liveability tools, including the UN Global Compact CityScan.

RESULTS

Findings revealed commonalities with the Australian liveability definition, as well as new potential indicators for Bangkok. The resulting Pilot Bangkok Liveability Framework provides a structure for measuring liveability in Bangkok that can be implemented by the Bangkok Metropolitan Administration immediately, pending appropriate data acquisition and licensing. The Bangkok Metropolitan Administration Working Group and key informants identified core issues for implementation, including limited spatial data available at the district-level or lower.

CONCLUSIONS

This study conceptualised urban liveability for Bangkok, a city in a LMIC context, with potential for adjustment to other cities. Future work should leverage opportunities for using open source data, building local capacity in spatial data expertise, and knowledge sharing between cities.

The geo-observer network: A proof of concept on participatory sensing of disasters in a remote setting

Effective disaster risk reduction is often hampered by a general scarcity of reliable data collected on disastrous events, particularly in the Global South. Novel approaches are therefore necessary to alleviate this constraint, particularly with regard to reducing extensive risks. A geo-observer network, consisting of 21 reporters, was established in the Rwenzori region (Uganda) in February 2017 to collect data on eight different disasters using smartphone technology. Within the first 15 months of operation, a total of 319 disaster reports were submitted. A large majority of the reported disasters were reached by the geo-observers within 2 days after their occurrence. The analysis of reporting activity shows a large divergence, with one third of the most active geo-observers accounting for nearly 75% of all reports. By using an existing landslide susceptibility map as a proxy of expected landslide prevalence, this reporting divergence is demonstrated to be at least partially driven by a difference in disaster occurrences. This is confirmed by the results of a survey held among the geo-observers. Survey results also showed that the participants are more driven by non-pecuniary benefits rather than financial compensation. The data collected during the first 15 months of operation indicates that extensive risks in the region are underestimated and demonstrates the added value of participatory sensing to compensate for the current lack of well-functioning official data collection mechanisms. This pilot project is a proof of concept for participatory sensing to collect high quality data even in remote contexts where smartphone technology is not generally adopted. It can serve as a precedent or example for other regions where extensive risks are poorly understood but pose significant threat to the population.

Cooperative urban mining in Brazil: Collective practices in selective household waste collection and recycling

Solid waste is a major urban challenge worldwide and reclaiming the resources embedded in waste streams, involving organized recyclers, is a smart response to it. Informal and organized recyclers, mostly in the global south, already act as important urban miners in resource recovery. The paper describes the complex operations of recycling cooperatives and draws attention to their economic, environmental, and social contributions. A detailed discussion based on empirical data from the recycling network COOPCENT-ABC in metropolitan São Paulo, Brazil, contextualizes this form of urban mining. The analysis is situated within Social and Solidarity Economy (SSE) and Ecological Economy (EE) theory. Current challenges related to planning, public policy, and the implementation of cooperative recycling are analysed on the level of individual recyclers, cooperatives, municipalities and internationally. There are still many hurdles for the informal, organized recycling sector to become recognized as a key player in efficient material separation and to up-scale these activities for an effective contribution to the SSE and EE. Policies need to be in place to guarantee fair and safe work relations. There is a win-win situation where communities and the environment will benefit from organized urban mining.
