Vulnerability of elderly people during climate-induced disasters in Sub-Saharan Africa: a scoping review

Climate-induced disasters present significant challenges to vulnerable populations, especially elderly individuals with disabilities who face unique difficulties in preparing for, responding to, and recovering from such catastrophic events. Despite growing concerns about the impact of climate-induced disasters in sub-Saharan Africa, there is a notable lack of information regarding the specific vulnerabilities experienced by elderly people with disabilities in this region. This study aims to address this gap by identifying and synthesizing the existing literature on the subject. Researchers conducted a scoping review, selecting articles from regional (Sabinet African Journals, Science Direct) and global databases (PubMed, PsycINFO, and ProQuest) using search strategies with Boolean operators, truncations, and MeSH terms. The review included primary studies (qualitative, quantitative, and mixed methods) published between 2013 and 2023 that met specified inclusion and exclusion criteria, with a focus on assessing the quality of the included studies. The findings revealed that elderly people in sub-Saharan Africa face significant physical, cognitive, and socio-economic challenges due to limited access to resources, inadequate infrastructure, and social exclusion. These challenges are amplified in the sub-Saharan context, highlighting a critical gap in inclusive risk reduction strategies during disasters. The review emphasizes an urgent need for targeted research and the development of community-based intervention programmes to improve the resilience and wellbeing of elderly individuals with disabilities facing climate-induced disasters. This study not only mapped the existing literature but also underscored the scarcity of research in the field of climate-induced disasters, with only six articles focusing on the elderly. The researchers recommend the development of more inclusive disaster risk reduction strategies and policies.

Assessment of crushed rock aggregates addition to granular lateritic materials in sub-Saharan extensive urbanization context (Yaoundé Cameroon) for road construction purposes

Granular lateritic materials (GLM) suitability for road construction after the addition of crushed rock aggregates (CRA) in the sub-Saharan extensive urbanization context was evaluated. The urbanization rate was made by using Landsat7 and Landsat8 radar images. The studied materials were subject to petrographic description and geotechnical analysis. The urbanized surface in the Yaoundé area increased by 41.88% from 2004 to 2020. The studied rock are gneisses composed of quartz, garnet, biotite, pyroxene, and feldspars. The gneisses obtained CRA have fines content of less than 10%, maximum dry density value of more than 2.00 g/cm3, good bearing capacity (CBR = 88%), and excellent mechanical characteristics (Los Angeles < 40%). This recommend their use as base course for low to medium volume traffic pavements. Gneisses-derived GLM, less load-bearing (CBR = 39 to 42%) than CRA, have limited behaviour in road construction and can be used as sub-base for all volume traffics. Their use in base courses requires prior treatment. CRA addition to these GLM result in the plasticity index decrease and compaction parameters improvement. CBR values increase shows a perfect correlation (R2 > 0.90) with the addition of CRA. Litho-stabilised materials (CBR ≥ 60%) can be used as base course for low-volume trafficked pavements. The addition of a CRA percentage greater than or equal to 25% is efficient for the optimization of their use. By reducing the amount of quarry aggregates, the improved material could be an economical alternative for road projects. This reduces and controls the haulage of materials within crowded urban area.

Factors influencing cervical cancer re-screening in a semi-rural health district of Cameroon: a cohort study

BackgroundScreening participation at recommended intervals is a crucial component of cervical cancer prevention effectiveness. However, little is known regarding the rate of re-screening in a Sub-Saharan context. This study aimed to estimate the re-screening rate of women in a semi-rural after an initial HPV-based screening and identify factors that influence adherence.MethodsThis cohort study at the Annex Regional Hospital of Dschang enrolled women screened for cervical cancer over 5 years ago and due for re-screening. Women who initially tested HPV-positive (n = 132) and a random sample of HPV-negative women (n = 220) participated in a telephone survey between October 2021 and March 2022 to assess re-screening participation and reasons. Sociodemographic factors were collected, and associations with rescreening were evaluated.ResultsA total of 352 participants aged under 50 years (mean age 37.4 years) were contacted, and 203 (58.0%) completed the survey. The proportion of women who complied with the screening recommendation was 34.0% (95% CI 27.5% − 40.5%), The weighted re-screening proportion was 28.4%. Age, marital status, education level, type of employment, and place of residence were not associated with the rate of re-screening. Main reported barriers to re-screening were lack of information (39.0%), forgetfulness (39.0%), and impression of being in good health (30.0%). Women who remembered the recommended screening interval were 2 to 3 times more likely to undergo re-screening (aOR (adjusted odds ratio) = 2.3 [1.2–4.4], p = 0.013). Human papilloma virus- positive status at the initial screening was also associated with the re-screening((aOR) (95% CI): 3.4 (1.8–6.5).ConclusionFollowing an initial Human Papilloma Virus-based screening campaign in the West Region of Cameroon, one third of women adhered to re-screening within the recommended timeframe. Existing screening strategies would benefit from developing better information approaches to reinforce the importance of repeated cervical cancer screening.

Assessing the potential of a niche market for wool products in South Africa

&lt;abstract&gt; &lt;p&gt;Ethical consumerism has been on the rise since the early 1900s; thus, increasing discerning consumers. Consumers place greater importance on intangible attributes such as the origin and societal and environmental impacts of the products. Studies focus on agricultural niche marketing in the South African and sub-Saharan context, but none focus on niche markets within the South African sheep wool industry. In this study, we investigated the niche market for local, handmade and socially responsible wool products in South Africa. Our methodology included interviews, a choice-based conjoint analysis and a multinomial logit model. The results revealed that South African high-income consumers preferred locally produced wool products over imported wool products. This was followed by consumers' preferring handmade over machine-made products as well as socially responsible wool products over those that provided no information on social responsibility. The existence of a niche market in South Africa was demonstrated when consumers preferred ethical wool products. We defined consumers' demographic and psychographic factors for a niche market. The findings can assist the South African wool industry and small-scale woolgrowers to identify niche markets for wool products by considering intangible attributes.&lt;/p&gt; &lt;/abstract&gt;

Using Photovoice to Illuminate Challenges Facing Children with Disabilities in Inclusive Education in Ghana

Achieving inclusive and quality education for all children remains a significant problem amidst several policies in sub-Saharan Africa. This study explores challenges facing children with disabilities in mainstream inclusive education-based basic schools in a sub-Saharan Ghanaian context. A qualitative photovoice approach was employed to highlight the experiences of six (6) pupils with disabilities. Findings revealed three main themes: unfriendly environments, inaccessible physical structures, and lack of assistive equipment, reflecting significant challenges confronting children with disabilities in inclusive education settings. Social support from colleagues without disabilities, however, acted as a major coping resource for pupils with disabilities. The study has implications for policy an

Management of Bladder Exstrophy in a Single Procedure: About a Case in the Urology Department of the CHU Point G

Bladder exstrophy is a rare urogenital birth defect. In the sub-Saharan context, most cases are diagnosed at birth or older due to lack of prenatal surveillance. The treatment is exclusively surgical. Several techniques have been described and modified over time. The surgical reconstruction technique can be done in a single or several procedures. This clinical observation was reported a case of complex epispadias bladder exstrophy, managed in a single procedure in a 10-year-old boy. The postoperative follow-up was simple.

Enabling factors for the development of mini-grid solutions in Mozambique: A PESTLE-based analysis

Electricity is crucial for each country's economic and social development. More than half of the population in Sub-Saharan African (SSA) lack access to energy, which has dire consequences for the local population's living conditions, as well as affecting the local economy and increasing poverty. Renewable energy-based mini-grid (REBM) systems are the promising solution to mitigate the issue of energy access in rural areas, however, the expansion of renewable energy (RE) systems and the rate of energy access are both advancing at a slow pace. This study used PESTLE analysis (Political, Economic, Social, Technological, Legal, and Environmental) in the context of Mozambique, a SSA country, to identify the most important categories and factors to support decision-making processes by breaking down existing barriers and hurdles in the energy sector enabling them to plan and implement measures, subdivided in primary, secondary and tertiary for the development of REBM in remote settlements. Even though PESTLE analysis is rather often worldwide applied to the energy sector, its application to the Sub-Saharan context is rare, while its application to the Mozambique energy sector is absent in scientific literature. Besides, within our study, energy experts from different professional backgrounds and nationalities have been interviewed using an online questionnaire: 62 energy experts (48 Africans, and 14 Non-African) from 14 different countries assessed the categories and factors. The experts questioned identified the political category as the most crucial for policy-makers to prioritize, with the top three global weighting factors being, Clear Government policies (plan, regulation, priority, strategy) 5.79%, National financial scheme for RES investments 4.93%, and cost of investment 4.86%. The findings can support policy-makers breakdown barriers in the energy sector, planning and implementing measures for the REBM development, and contribute to achieving the SDG7 target.

Global Perspectives: Exploring Disruptive Technology Challenges for Consumers in Sub-Saharan Africa

The Base of Pyramid markets in Sub-Saharan Africa face challenges such as poverty, poor infrastructure, illiteracy, and government corruption. This paper examines and presents an analytical review of the difficulties among consumers in Sub-Saharan Africa using academic institutions in Kenya to illustrate disruptive technology. Sub-Saharan Africa is faced with practical challenges with disruptive technology. Qualitative analysis is conducted among a sample from Kenya to assess the validity of challenges faced in academia. The authors use stratified sampling to select the local population and reach higher precision with a response rate of 85%. The qualitative analysis findings confirm a positive relationship between smart devices and network reliability, online teaching, online grade book, and virtual learning. The authors conclude that network reliability is the most challenging, especially for higher education institutions moving forward with adopting mobile learning. There exists a research gap in the literature on the Sub-Saharan Context. The challenges of disruptive technology and academia within Sub-Saharan Africa were limited to Kenya. Further research by practitioners and scholars can explore the challenges of disruptive technology in Sub-Saharan Africa.

How do markets react to political elections during periods of insecurity and governance crises? Evidence from an African emerging democracy

PurposeThis paper operationalizes insecurity and governance crises to study their effects on stock market response to two political events in Nigeria – the 2015 and 2019 presidential elections.Design/methodology/approachAn event study was used to capture the market responses. Abnormal returns at the aggregate and sectoral levels were measured over several time windows before and after the respective election results were announced.FindingsThe market reacted strongly positively to a change in presidency from an incumbent to an opposition party candidate in the 2015 election but weakly positively, at best, to the re-election of the incumbent candidate in the 2019 election. In addition, banking stocks exhibited greater sensitivity to these events than oil and gas stocks.Research limitations/implicationsThere may be peculiarities with the Nigerian case and with the two elections analyzed. Therefore, future research could focus on understanding the extent to which the results generalize to the broader sub-Saharan context and other regions that face similar governance challenges.Practical implicationsUnderstanding that markets may have a different perception towards incumbent versus opposition candidate electoral victories during periods of insecurity and governance crisis is important for investors, policymakers, researchers and the wider society.Originality/valuePast empirical studies on political events and stock returns in Sub-Saharan Africa contexts such as Nigeria ignore shifts in voter mood and produce contradictory findings. This paper helps to resolve some of these contradictions by providing insight into how the markets can have a different perception towards incumbent and opposition candidate electoral victories during periods of insecurity and governance crisis.

African Off-grid Housing

Today, 600 million people in Africa do not have access to electricity and 900 million lack access to clean cooking facilities (International Energy Agency- 2019).&#x0D; With this premise the paper will explain the research agenda of the African Off-grid Housing project on how to design and build off-grid and affordable housing solutions for the African Sub-Saharan context. The on-going project is developed at the School of Architecture and Cities of the University of Westminster with the support of the Global Challenge Research Fund. The research agenda is based on the idea of producing innovative knowledge able to bridge traditional and advanced design strategies as well as construction technologies in response to the urgent need of affordable housing in the African region. Therefore, the [AOH] research by design methodology is informed by the analytical study of the cause-effects relations between the architectural geometry, the material systems and the environmental performances of a set of pre-colonial and contemporary precedents in relation to their climatic context.&#x0D; According to this analysis the most flexible and affordable vernacular genotype was selected, integrated and evolved according to a series of contemporary performative criteria through a design methodology based on a parametric approach.&#x0D; Therefore, the form finding of this initial housing genotype was informed by the negotiation between the sitespecific climatic conditions, the spatial and energy needs of local users and the material systems available on-site. The performative criteria of the form finding included the question of self-sufficiency in relation to energy, water and food accessibility. The best negotiation between the different criteria, has been selected and developed as a paradigm to generate a design protocol and a construction kit open to possible variations in terms of scalability and incrementality.

Hydrogen technology in Sub-Saharan Africa: Prospects for Power Plants

Hydrogen as an energy vector could be one of the solutions to the crucial energy crisis in sub-Saharan Africa. A technological review is done in this paper as a first attempt to foster research and development on the subject. It shows the hydrogen technology disadvantages and difficulties regarding its usage in Africa, and explores ways to better tackle them. Concepts are also discussed by showing the benefits of hydrogen introduction in sub-Saharan African countries on their economy through the increase of their electrification coverage and the reduction of electricity shortages witnessed in these countries. Ideas of systems hybridization including hydrogen fuel cells are presented, discussed and adapted to the sub-Saharan context. Methods of overcoming possible risks, technologies that could be adopted now and on-going research on the subject are finally performed.

Quality financial inclusion and its determinants in South Africa: evidence from survey data

PurposeThe study measured quality financial inclusion, a more comprehensive measure of financial inclusion, and examined its determinants at a consumer level in South Africa.Design/methodology/approachThis study leveraged on FinScope 2015 survey data to compute a quality financial inclusion index using polychoric principal component analysis. Subsequently, a heteroscedasticity consistent ordinary least squares regression model was employed to assess determinants of quality financial inclusion.FindingsThe empirical findings indicated that gender, education, financial literacy, income, location and geographical proximity determine quality financial inclusion. These findings could inform policymakers and financial services providers on how quality financial inclusion can be promoted through tailoring financial products for various socio-demographic groups.Research limitations/implicationsDue to data limitations, the study was confined to South Africa and did not capture digital financial inclusion. Hence, future studies could replicate the study in Sub-Saharan Africa's context and compute an index that captures digital financial inclusion.Practical implicationsThese findings could inform policymakers and financial services providers on how quality financial inclusion can be promoted through tailoring financial products for various socio-demographic groups.Originality/valueThis study proposed a more comprehensive measure of quality financial inclusion from a demand-side perspective by accounting for important dimensions that include diversity, affordability, appropriateness and flexibility of financial products and services.

Contextualization of critical thinking in sub-Saharan Africa: A systematic integrative review

Cultural norms affect the efficacy of critical thinking instruction. In several sub-Saharan African countries, governments have publicly declared critical thinking skills to be a major educational priority to increase global economic competitiveness. However, many schools and education systems have not taken action to translate the stated government policies into revised curricula, pedagogies and assessment frameworks. Faced with these challenges, the overall objective of the study is to analyse, by means of an integrative systematic review, how the concept, implementation and assessment of critical thinking has been contextualized in sub-Saharan Africa. Of the 51 documents that met the inclusion criteria, a total of 5 categories, 95 codes, and 1,075 quotes were analysed. The findings highlight that researchers and practitioners apply western concepts of critical thinking to the sub-Saharan context without questioning its actual transferability. Moreover, the analysis shows that there is a lack of familiarity with adaptation strategies of assessment tools and teaching methods in sub-Saharan Africa.

Talent retention strategies for female academics in the higher education sector

This study aimed at identifying talent retention strategies for female academics in the higher education sector, paying particular attention to the Sub-Saharan context. Higher education institutions rely on the knowledge, abilities, and skills of their academics in order to keep abreast of the changing nature of higher education globally. These institutions of higher learning are required to be competitive and achieve their strategic goals in order to remain relevant in the sector. Studies have shown that female academics are leaving the higher education sector for the private sector for numerous reasons, including better salaries and further development. Additionally, some female academics are emigrating to European countries in search of greener pastures. Therefore, higher education institutions have to ensure that talent retention strategies are implemented to retain female academics, as well as to facilitate their progress to top leadership positions. The study utilized four crucial retention strategies identified in Kenya by Mutiria, Rukangu and Kubaison in 2015. These retention strategies include compensation and benefits, formal succession planning, training and development and career development opportunities. A quantitative research design was adopted for this study, whereby online questionnaires were completed by 112 female academics at a Sub-Saharan university. The data were analyzed using the Statistical Package for the Social Sciences (SPSS) version 27 for Windows. The results revealed a significant relationship between the four identified strategies and retention. Thus, institutions of higher learning should effectively implement these strategies in order to retain talented female academics, considering the dynamics in the sector.

A case for green-based vegetation indices: plot-scale sUAS imagery related to crop chlorophyll content on smallholder maize farms in Malawi

ABSTRACT Predictable outcomes from precision agriculture (PA) solutions require accurate measurements of crop status and a remote sensing knowledgebase that spans ecoregions. This paper evaluates the relationships between 20 multispectral vegetation indices derived from small unmanned aircraft system (sUAS) image collection and on-farm measurements of crop chlorophyll content at two smallholder experimentation maize farms in Malawi with varied nitrogen fertilizer treatments. Results of this analysis show that prominent green-based multispectral indices, such as the green normalized difference vegetation index (GNDVI), were among the models with the strongest correlations. This study is consistent with other research in this field, contributes to mounting evidence supporting a shift in status quo for greater adoption of green-based indices in PA, and offers data specific to the semi-arid sub-Saharan context.

Flood Mitigation Measure and Water Storage in East Africa: An Analysis for the Rio Muaguide, Mozambique

In the last century, floods have been more frequently hitting population and human activity, especially in the sub-Saharan context. The aim of this study is to propose suitable flood mitigation measures for the downstream part of the Rio Muaguide, which flows in northern Mozambique. In this terminal part of the river, the bed has been buried by sediment in many reaches; due to the reduction of the section conveyance, wide areas are inundated during the rainy season with negative consequences for several villages relying on subsistence agriculture. The design of any measure requires quantitative determinations but, as many less developed countries, Mozambique is affected by data scarcity. Therefore, in this study global and freely available data have been used to perform hydrologic and two-dimensional hydro-dynamic modelling, finally producing a flood hazard map. Particular care has been put into a critical analysis of several data sources, in terms of their suitability for the purposes of the work. Based on the modelling results and on field evidence, an intervention has been proposed with a double functionality of mitigating the effects of periodic floods and storing water to be used by the agricultural community during drier seasons. The proposed intervention combines restoring a sedimentation-less shape of the river sections and exploiting a natural basin as a storage basin. The methods applied and the intervention proposed for the Rio Muaguide are prototypal for several analogous streams in the coastal portion of Mozambique.

Informal work in sub-Saharan Africa: Dead end or stepping-stone?

Abstract Despite rapid economic growth in recent decades, informality remains a persistent phenomenon in the labor markets of many low- and middle-income countries. A key issue in this regard concerns the extent to which informality itself is a persistent state. Using panel data from Ghana, South Africa, Tanzania, and Uganda, this paper presents one of the very few analyses providing evidence on this question in the context of sub-Saharan Africa. Our results reveal an important extent of heterogeneity in the transition patterns observed for workers in upper-tier versus lower-tier informality. Given the limited alternative job opportunities available, particularly to those in lower-tier informal self-employment who often remain locked in a situation of inferior pay and conditions, specific policies that seek to enhance the livelihoods of workers in this most disadvantaged segment may be more relevant in the sub-Saharan context than policies that aim to reduce the regulatory barriers to formalization.

Assessing and coping with the financial burden of computed tomography utilization in Limbe, Cameroon: a sequential explanatory mixed-methods study

BackgroundThere has been a significant increase in computed tomography (CT) utilization over the past two decades with the major challenges being a high exposure to ionizing radiation and rising cost. In this study we assess the risk of financial hardship after CT utilization and elaborate on how users adapt and cope in a sub-Saharan context with user fee for services and no national health insurance policy.MethodsWe carried out a sequential explanatory mixed methods study with a quantitative hospital-based survey of CT users followed by in-depth interviews of some purposively selected participants who reported risk of financial hardship after CT utilization. Data was summarized using frequencies, percentages and 95% confidence intervals. Logistic regression was used in multivariable analysis to determine predictors of risk of financial hardship. Identified themes from in-depth interviews were categorized. Quantitative and qualitative findings were integrated.ResultsA total of 372 participants were surveyed with a male to female sex ratio of 1:1.2. The mean age (standard deviation) was 52(17) years. CT scans of the head and facial bones accounted for 63% (95%CI: 59–68%) and the top three indications were suspected stroke (27% [95%CI: 22–32%]), trauma (14% [95%CI: 10–18%]) and persistent headaches (14% [95%CI: 10–18%]). Seventy-two percent (95%CI: 67–76%) of the respondents reported being at risk of financial hardship after CT utilization and predictors in the multivariable analysis were a low socioeconomic status (aOR: 0.19 [95%CI: 0.10–0.38]; p < 0.001), being unemployed or retired (aOR: 11.75 [95%CI: 2.59–53.18]; p = 0.001) and not having any form of health insurance (aOR: 3.59 [95%CI: 1.31–9.85]; p = 0.013). Coping strategies included getting financial support from family and friends, borrowing money and obtaining discounts from the hospital administration and staff.ConclusionNo health insurance ownership, being unemployed or retired and a low socioeconomic status are associated with financial hardship after CT utilization. Diverse coping strategies are utilized to lessen the financial burden, some with negative consequences. Minimizing out-of-pocket payments and/or the direct cost of CT can reduce this financial burden and improve CT access.
