In this paper I ask how the ongoing processes of urban and local government development in Sub-Saharan Africa can and should benefit the countries, and what conditions must be met to achieve this favourable outcome. The region faces close to a doubling of the urban population in fifteen years. This urban transition poses an opportunity as well as a management challenge. Urban areas represent underutilised resources that concentrate much of the countries' physical, financial, and intellectual capital. Therefore it is critical to understand how they can better serve the national growth and poverty reduction agendas. The paper challenges several common ‘myths’ that cloud discourse about urban development in Africa. I also take a hard look at what the urban transition can offer national development, and what support cities and local governments require to achieve these results. I argue that, rather than devoting more attention to debating the urban contribution to development in Africa, real energy needs to be spent unblocking it.

AbstractThe potential benefits of obstetric ultrasound have yet to be fully realized in sub-Saharan Africa (SSA), despite the region bearing the greatest burden of poor perinatal outcomes. We reviewed the literature for challenges and opportunities of universal access to obstetric ultrasound and explored what is needed to make such access an integral component of maternity care in order to address the massive burden of perinatal morbidity and mortality in SSA. Original peer-reviewed literature was searched in various electronic databases using a ‘realist’ approach. While the available data were inconclusive, they identify many opportunities for potential future research on the subject within the region that can help build a strong case to justify the provision of universal access to ultrasound as an integral component of comprehensive antenatal care.

This paper presents the role of ICTs in transforming Africa’s Education Systems (AES) in science, technology, engineering, and mathematics (STEM) subjects/courses. The paper highlights on a positive shift across Africa in using ICT to improve the quality of teaching and learning through activities such as intensive ICT skills training to teachers, increase in ICT equipments and applications in schools, and emergence of living labs (LLs) and innovation spaces/centres (InnoSpace). We first provide some of the challenges of integrating ICTs in education followed by a description of key past and current ICT initiatives supporting the adoption of ICTs in schools using a number of case studies in sub-Saharan Africa. We further present various ICT-based models for education, as a transformational approach towards integrating ICTs in AES. Moreover, we provide various ICT platforms deployed for education service delivery in disadvantaged African society (e.g., rural areas) including LLs and InnoSpace across the continent. Finally, we highlight our main findings and observations in terms of opportunities and future ICT for education research directions in Africa. Our aim is to provide some guidelines and ensure that Africa uniformly meet the 2030 United Nations Sustainable Development Goal number 4, which is to ensure inclusive and quality education for all and promote lifelong learning, particularly using ICTs.

Much of our methodological insights from researching policing in sub-Saharan Africa comes from studies of frontline officers. Consequently, many important methodological questions about research on senior police officers remain unanswered. This article addresses this gap by drawing on insights from interviewing senior officers in Ghana. It focuses on the challenges and opportunities in negotiating access, establishing trust during interviews and dealing with ethical dilemmas. We highlight the role of informal social networks and cultural practices of surprise visits, what we have termed strategic ambush, in securing formal approval for our research. However, this represented mere or putative access for which deference towards institutional gatekeepers was key to its actualization. Deference towards officers and extensive knowledge of the policing environment helped to put the senior officers at ease, and enhanced the chances of a successful interview. Finally, we offer reflections on our responses to unexpected ethical dilemmas that we faced in the field.

AbstractThe lack of adequate techniques for food processing is among the reasons underlying food losses and high levels of hunger in Sub-Saharan Africa; the application of solar energy to dry agricultural products is one potential solution. However, the total replacement of traditional uses of solar energy is still far from reality. Therefore, in this study, we systematically review the academic literature testing passive solar drying systems in order to assess their performance. Then the main limitations and challenges for passive solar dryers developed in Sub-Saharan Africa are derived. The literature search reveals very limited research and a lack of standardized methods to assess solar dryer performance. Studies mainly report parameters related to dryers’ thermal performance and physical features, thus neglecting parameters related to the quality of dried products and economics. Standardized and robust methodologies are urgently needed for more accurate conclusions and comparability of study results. Moreover, successfully applying passive solar dryers as an alternative to the traditional use of solar energy requires overcoming challenges such as time consumption, limited quantities of dried products, and the periodic nature of solar radiation. Thus, given its ability to significantly improve the self-life of food and overcome the current limitations for effective utilization of solar dryers in SSA, the use of mixed mode passive greenhouse dryers is proposed.
