Item Defining ‘Smart Rural’ in the Framework of Regional Digitalisation(IST-Africa 2021 Conference Proceedings, 2021) Lindblom, P.; Kolog , E.A.; Nygren, E.; Sutinen, E.In this paper, we explored how a smart development framework could be harnessed for enhancing small and medium enterprise (SME) activities in rural communities. With this aim, this study considered and compared the landscape of the SME ecosystems in Ghana and Finland. Alongside the deprived countryside or remote work context, it has become clear that contemporary digital platforms and collaborative media represent an integral part of smart development. In addition, remote working possibilities help tackle challenging times or even a state of emergency, such as the ongoing COVID-19 crisis. We created our Smart rural development model (SRDm) to facilitate the digital transformation of SMEs and strategies in peripheral settings. Our SRDm was developed from the exploration of smart development literature in regional settings, and filtering numerous initiatives utilutilizedhin digitalization SME development context. The key target groups who can benefit from our research endeavor are the various strategic development organizations, financing authorities, and of course regional stakeholders, policymakers, business clusters, SMEs, and individuals.Item What influences cancer treatment service access in Ghana? A critical interpretive synthesis(BMJ Open, 2022) Tuck, C.Z.; Aryeetey, R.N.O.; Akparibo, R.; et al.Objectives Multiple social-cultural and contextual factors influence access to and acceptance of cancer treatment in Ghana. This research aimed to assess the existing literature on how these factors interplay and could be susceptible to local and national policy changes. Design This study uses a critical interpretive synthesis approach to review qualitative and quantitative evidence about access to adult cancer treatment services in Ghana, applying the socioecological model and candidacy framework. Results Our findings highlighted barriers to accessing cancer services within each level of the socioecological model (intrapersonal, interpersonal community, organizational and policy levels), which are dynamic and interacting, for example, community-level factors influenced individual perceptions and how they managed financial barriers. Evidence was lacking about determinants of treatment non-acceptance across all cancers and in the most vulnerable societal groups due to methodological limitations. Conclusions Future policy should prioritize multilevel approaches, for example, improving the quality and affordability of medical care while also providing collaboration with traditional and complementary care systems to refer patients. Research should seek to overcome methodological limitations to understand the determinants of accessing treatment in the most vulnerable populations.Item Land Governance and Conflict in West Africa through Interdisciplinary Empirical Lenses(Merian Institute for Advanced Studies in Africa (MIASA), 2024-09) Narh, P.; Doumbia, L.; Tounkara, A.; Ablo, A.D.This working paper addresses the following central questions: (i) How does the commodification of land challenge distinctions between rural and urban spaces? (ii) What new forms of differentiation emerge from commodification, for example the alienation of land markets from land governance regimes? (iii) How does commodification help our understanding of the resilience of custom and egalitarianism? (iv) How useful are property rights frameworks, whether customary, statutory or new forms of tenure, for land management and sustainability? Four authors, members of the MIASA Interdisciplinary Fellow Group (IFG 6) on Land Governance, applied ethnographic and cross-sectional research methods to examine case studies in Ghana, Mali and Senegal. This research contributes to an understanding of the perceptions, discourses and practices relating to land commodification and conflicts, as well as the way in which endogenous perceptions of access to land in West Africa are expressed and adapt to changing circumstances.Item Equity and expertise in the UN Food Systems Summit(BMJ Global Health, 2021) Nisbett, N.; Aryeetey, R.; Friel, S.; et al.The UN Food Systems Summit is bold but controversial, with important implications for global food systems and public health. ► Alongside claims of corporate capture, many have noted insufficient attention paid to human rights and to rebalancing power in the food system. ► These issues speak to wider issues of participation and equity in the summit itself. Narrow definitions of equity only consider income inequities in outcomes and coverage. Broader definitions consider why such inequities persevere and are interlinked via process es that can be historical and intergenerational. ► The summit’s science group is slanted in disciplinary expertise: it lacks sufficient expertise in equity, health, and noncommunicable diseases, or representatives with expertise in Indigenous knowledge. ► It is not too late to rectify this in the summit structures, as we approach the September summit meeting.Item Exploring soil pollution patterns in Ghana’s northeastern mining zone using machine learning models(Journal of Hazardous Materials Advances, 2025) Kwayisi, D.; Kazapoe, R.W.; Alidu, S.; et al.This study assessed the pollution status and effectiveness of machine learning models in predicting pollution indices in soils from a mining area in Northeastern Ghana. 552 soil samples were analysed with an Energy Dispersive X-ray Fluorescence (ED-XRF) spectrometer for their elemental concentrations. Four pollution indices; Nemerow Integrated Pollution Index (NIPI), degree of contamination (Cdeg), modified degree of contamination (mCdeg) and Pollution Load Index (PLI). Additionally, the Multivariate Adaptive Regression Splines (MARS) machine learning approach were used. The high CV%, skewness, and kurtosis values show a high degree of variability and uneven distribution patterns which denotes dispersed hotspots that can be interpreted as an influence of gold anomalies and illegal mining activities in the area. V (120.86 mg/L), Cr (242.42 mg/L), Co (30.92 mg/L) Ba (337.62 mg/L), and Zn (35.42 mg/L) recorded values higher than the global and regional contaminant thresholds. The NIPI shows that 46.74% and 26.81% of samples are slightly and moderately polluted respectively. The Cdeg analysis supports these findings, with 36.96% and 41.49% of samples classified as having “moderate” to “considerable” contamination, respectively. The PLI indicates progressive soil quality deterioration (43.84%) of samples reflecting substantial environmental disturbance. The pollution indices show the effect of illegal mining on Shaega, Buin and other areas in the eastern boundary of the study. The MARS models developed for the study demonstrated high predictive capabilities with an R2 value of 0.9665 for model 1 (NIPI), and RMSE and MAE values of 0.8227 and 0.4287 respectively. For model 2 (Cdeg), R2 value of 0.9863, RMSE and MAE of 1.0416 and 0.6181, respectively. Model 3 (mCdeg) produced an R2 value of 0.9844, RMSE and MAE of 0.1225 and 0.0670. These findings suggest MARS models can be an integral tool for soil quality analysis in cooperation with pollution indices. The study suggests that remedial and legislative measures be implemented to address the issue of illegal mining in the area.Item The potential for index-based crop insurance to stabilize smallholder farmers' gross margins in Northern Ghana(Agricultural Systems, 2024) Adelesi,O.O.; Kim,Y.U.; Schuler,J.; Zander,P.; Njoroge,M.M.; Waithaka,L.; Abdulai,A.L.; MacCarthy,D.S.; Webber,H.Context: Smallholder farmers in semi-arid West Africa face challenges such as weather variability, soil infertility, and inadequate market infrastructure, hindering their adoption of improved farming practices. Economic risks associated with uncertain weather, production and market conditions often result in measures such as selling assets and withdrawing children from school, resulting in long-term impoverishment. To break these poverty traps, there is a need for affordable and sustainable risk management approaches at the farm level. Proposed strategies include risk reduction through stress-resistant crop varieties and diversification, additional investments transfer options like crop insurance and contract farming. Despite experimentation with insurance products in sub-Saharan Africa, low adoption persists due to many factors including high premiums, imperfect indices, and cognitive factors.Item Urban physical food environments drive dietary behaviours in Ghana and Kenya: A photovoice study(Health and Place, 2021) Pradeilles, R.; Laar, A.; Irache, A.; et al.We identified factors in the physical food environment that influence dietary behaviours among low-income dwellers in three African cities (Nairobi, Accra, Ho). We used Photovoice with 142 males/females (≥13 years). In the neighbourhood environment, poor hygiene, environmental sanitation, food contamination and adulteration were key concerns. Economic access was perceived as a major barrier to accessing nutritionally safe and healthy foods. Home gardening supplemented household nutritional needs, particularly in Nairobi. Policies to enhance food safety in neighbourhood environments are required. Home gardening, food pricing policies and social protection schemes could reduce financial barriers to safe and healthy diets.Item The burden of iatrogenic obstetric fistulas in Sub-Saharan Africa: Systematic review and meta-analysis protocol(PLOS ONE, 2024) Imakando, M.M.; Maya, E.; Owiredu, D.; et al.Background Obstetric fistulas are abnormal open connection(s) between the vagina and the urinary tract or the rectum resulting from tragic injuries sustained by mothers during childbirth that lead to urine and/or faecal incontinence. Due to the rapidly growing middle class in sub-Saharan Africa (SSA) and the corresponding quest for hospital delivery and caesarean section, surgery-related (iatrogenic) obstetric fistulas are on the rise. Worryingly, there is scanty data on surgery-related fistulas. This review aims to collate empirical evidence on the magnitude of iatrogenic obstetric fistulas in SSA, generate country-specific data and explore factors that influence obstetric surgery-related fistulas. Methods All relevant databases, PubMed, LILACS, CINAHL, SCOPUS and Google Scholar will be searched from 1st January 2000 to 31st March 2024 using search terms developed from the major concepts in the title without restrictions by language. The Cochrane Library, African Journals Online, Data Base of African Thesis and Dissertations Including Research (DATAD-R D Space) and preprint repositories will also be searched. Reference lists of relevant studies will be searched and experts in the field will be contacted for additional (unpublished) studies. The search output will be exported to Endnote where duplicate studies will be removed. The deduplicated studies will be exported to Rayyan where study screening and selection will be conducted. At least two authors will independently select studies, extract data and assess quality in the included studies using pretested tools. Disagreements between reviewers will be resolved through discussion. Data analysis will be performed with RevMan 5.4. Comparative binary outcomes will be reported as odds ratio (OR) or risk ratio (RR) and for continuous outcomes, mean difference and standard deviations (SDs) will be used. Non-comparative studies will be analysed as weighted proportions. Heterogeneity between studies will be assessed graphically and statistically, and where a significant level is detected, the random-effects model meta-analysis will be performed. All estimates will be reported with their 95% confidence intervals (CIs). Where data permit, we will conduct sub group and sensitivity analyses to test the robustness of the estimates on key quality domains. The overall quality of the evidence will be assessed using GRADE (Grading of Recommendations Assessment, Development and Evaluation).Item The Role of Cultural Heterogeneity in Strengthening the Link Between Family Relationships and Life Satisfaction in 50 Societies(Journal of Happiness Studies, 2024)We argue that the importance of family relationships for individual well-being varies across societies as a function of a society’s degree of cultural heterogeneity. To examine the role of family relationships, we analyzed the responses from 13,009 participants in 50 societies on their life satisfaction across societies varying in their levels of historical and contemporary cultural heterogeneity. Such heterogeneity creates differences in the frequency of interacting with unfamiliar groups, which leads families to become more central to their members’ satisfaction with life. Multi-level analyses showed that historical and contemporary cultural heterogeneity moderated the pattern such that greater historical or contemporary cultural heterogeneity of society promoted a stronger positive relation between family relationship satisfaction and individual life satisfaction. Our results also revealed that the moderating role of historical cultural heterogeneity was more reliable than that of contemporary cultural heterogeneity. These findings demonstrate the importance of societal demography in shaping people’s psychological processes in different historical periods, suggesting a universal, trans-historical cultural process.Item Situational assessment and epidemiology of HIV, HBV and HCV among people who use and inject drugs in Ghana(PLOS ONE, 2024) Guure, C.; Dery, S.; da Silva, C.B.; et al.Introduction People who inject drugs (PWID) and people who use drugs (PWUD) are an important popu lation group that remain under-served in Ghana. Though PWID and PWUD are among the key populations most-at-risk to acquire sexually transmitted or blood-borne diseases, they are among those with the least access to human immunodeficiency (HIV), hepatitis B (HBV) and hepatitis C (HCV) viruses’ prevention, care and treatment services in Ghana due to lack of data on them. We provide a rapid assessment of the PWUD and PWID situation in Ghana. Methods This rapid cross-sectional design undertook consultative meetings between the study team and relevant stakeholders, including Civil Society Organizations (CSO) working with PWUD/PWID. The assessment considered a representative sample of PWID and PWUD. It was conducted in four (4) selected regions of Ghana (Greater Accra, Ashanti, Western, and Northern). Overall, 323 participants were interviewed using respondent-driven sampling (RDS) approach. Information obtained from participants were demographics, HIV risk behaviors, human immunodeficiency (HIV) and sexually transmitted infections (STI)-related knowledge HIV/HCV/HBV screening, attitude, and practices among others. Analyses were conducted using Stata version 17 and RDSAT version 7.1.46 software. Findings Drug use was found to be more prevalent among the youth with a median age of 37 years. Majority of the respondents were males (86%). About 28% of the female respondents identi fied themselves as sex workers, while about 74% have been involved in transactional sex. The median age at which respondents started using and injecting drugs was 20 and 22 years respectively. Majority (68%) of the respondents consume drugs through smoking, with 20% through snorting, inhaling or swallowing and 12% through injection. The drug mostly used among the respondents was heroin (52%). The most commonly injected drug was cocaine (55%). About 64.7% of respondents reported mixing two or more drugs. HIV prevalence among respondents was 2.5%, 12.3% among women and 17.7% among women engaged in sex work, highlighting the overlap vulnerability. The prevalence of hepa titis C was 6.0%, and Hepatitis B was 4.5%. Access to care is limited, with 63% of the respondents never been tested for HIV. Conclusion These rapid assessment findings reveal the challenging conditions for people who use and inject drugs coupled with a relatively high prevalence of HIV and Hepatitis C compared to the general population. However, it also reveals that Ghana has a window of opportunity to prevent an exponential spread of HIV and Hepatitis in this population. Therefore, there is the need to implement prevention and treatment programs for HIV and hepatitis among people who use and inject drugs including essential strategies for an enabling environment in Ghana.
