Energy communities have received considerable attention in the Global North, especially in Europe, due to their potential for achieving sustainable energy transitions. In Sub-Saharan Africa (SSA), energy communities have received less attention partly due to the nascent energy systems in many emerging SSA states. In this paper, we argue that these nascent energy systems offer an opportunity to co-create energy communities that can tackle the energy access challenges faced by most SSA countries. To understand how such energy communities are realised in the sub-region, we undertake a systematic review of research on energy communities in 46 SSA countries. Our findings show that only a few energy projects exhibit the conventional characteristics of energy communities; In most of these projects, local communities are inadequately resourced to institute and manage their own projects. We thus look to stakeholder engagement approaches to propose co-design as a strategy for strengthening energy communities in SSA. We further embed our co-design proposal in energy democracy thinking to argue that energy communities can be a pathway towards equity and energy justice in SSA. We conclude that energy communities can indeed contribute to improving energy access in Africa, but they need an enabling policy environment to foster their growth and sustainability.

Hybrid Renewable Energy

Hybrid Renewable Energy Systems (HRESs) have been touted as an appropriate way for supplying electricity to remote and off-grid areas in developing countries, especially in sub-Saharan Africa (SSA), where rural electrification challenges are the most pronounced. This study proposes a two-step methodology for optimizing and analyzing a stand-alone photovoltaic/wind/battery/diesel hybrid system to meet the electricity needs of Fanisua, an off-grid and remote village of northern Nigeria. In the first step, the MATLAB environment was used to run simulations and optimize the system via the genetic algorithm. Then, techno-economic and emissions analysis was carried out in the second step to compare the proposed system to the existing traditional modes of rural electrification in sub-Saharan Africa, namely, the grid-extension and diesel generator. The break-even distance parameter was adopted in the comparison with grid-extension. Besides, the hypothetical project of replacing the diesel generator by the optimal system was analyzed using the Simple Payback Period (SPP) and Net Present Value (NPV) parameters. The resulting optimal design architecture included an 89.271-kW photovoltaic array, a 100.31-W diesel generator, and 148 batteries with a total annualized cost (TAC) and cost of energy (COE) of USD 43,807 and USD 0.25/kWh, respectively. The break-even distance found was 16.2 km, while the NPV and SPP of the hypothetical project were USD 572,382 and 2.8 years, respectively. The savings in carbon dioxide (CO2) emissions of the proposed system compared to the grid extension and the diesel generator were found to be 85,401.08 kg/year and 122,062.85 kg/year, respectively. This study highlighted the role that solar PV-based HRESs could play in the sustainable electricity supply in rural areas of sub-Saharan Africa.

Risk Knowledge

Risk-sensitive urban development is required to reduce accumulated risk and to better consider risk when planning new developments. To deliver a sustainable city for all requires a more frank and comprehensive focus on procedure: On who makes decisions, under which frameworks, based upon what kind of data or knowledge, and with what degree and direction of accountability? Acting on these procedural questions is the promise of transformative urban development. This paper explores the status of risk sensitive and transformative urban development and the scope for transition towards these components of sustainability in urban sub-Saharan Africa through the lens of diverse city cases: Karonga (Malawi), Ibadan (Nigeria), Niamey (Niger) and Nairobi (Kenya). The paper draws from a 3-year research and capacity building programme called Urban Africa: Risk Knowledge that aims to address gaps in data, understandings and capacity to break cycles of risk accumulation. A common analytical framework is presented to help identify blockages and opportunities for transition towards a risk-sensitive and transformative urban development. This framework is then illustrated through each city in turn and a concluding discussion reflects on city observations to draw out recommendations for city level and wider action and research partnerships.

The global sustainable development agenda, the Sustainable Development Goals (SDGs), places energy systems—technologies to improve energy access, increase renewable energy generation, and tap energy efficiency—at its core to deliver what the United Nations General Assembly envisaged to be sustainable development for “people, prosperity and planet.” But a fourth “p”—for politics—needs to be enmeshed in this framework. This chapter maps the extant literature on the connections between the politics of energy systems and sustainable development in sub-Saharan Africa, a region where most of the world’s energy poor live. A focus on the politics of energy and sustainable development for people, prosperity, and planet remains a rich, yet understudied, frontier for future research. This chapter suggests an inclusive, interdisciplinary, and influential research agenda.

Urban development in the last four decades has brought a complete change to the urban image of Gaborone. Its original savannah landscape and surrounding green complexion has changed by cumulative impacts of numerous factors involved in creation of a contemporary settlement, from a small village to the capital city of Botswana. The concept of a "garden city" was introduced immediately after the country gained its independence from the British in 1966. Building on the legacy of "garden city", it was assumed that the "new town" will continue to shape and gain recognition as an urban oasis. However, this was not the case and Gaborone became the fastest growing urban laboratory in Sub-Saharan Africa, portraying intensive diffusion and adoption of imported urban models (WARD, 1999). The spectacular population increase from only 7,000 people in 1966 to almost 200,000 in 2001, and urban sprawling were inevitable. This enlargement was fuelled by rural-urban migration owing to the administrative and economic status of Botswana's new capital, as well as, due to intensive urbanization, industrialization and transportation based on individual car use. Even in the latest city development plan (GoB, 2001) less attention has been paid to the role of green networks and areas, and their contribution to many ecological and societal values. Today, Gaborone is facing the challenge of the typical problems of mega-cities, such as environmental degradation, urban sprawl. The research project DIMSUD is dedicated to identify ways toward sustainable urban development, starting with an analysis of challenges, and continuing with the tasks for urban planning and opportunities for sustainable urban development.

RTS,S/AS01 is the most advanced vaccine to prevent malaria. It is safe and moderately effective. A large pivotal phase III trial in over 15 000 young children in sub-Saharan Africa completed in 2014 showed that the vaccine could protect around one-third of children (aged 5–17 months) and one-fourth of infants (aged 6–12 weeks) from uncomplicated falciparum malaria. The European Medicines Agency approved licensing and programmatic roll-out of the RTSS vaccine in malaria endemic countries in sub-Saharan Africa. WHO is planning further studies in a large Malaria Vaccine Implementation Programme, in more than 400 000 young African children. With the changing malaria epidemiology in Africa resulting in older children at risk, alternative modes of employment are under evaluation, for example the use of RTS,S/AS01 in older children as part of seasonal malaria prophylaxis. Another strategy is combining mass drug administrations with mass vaccine campaigns for all age groups in regional malaria elimination campaigns. A phase II trial is ongoing to evaluate the safety and immunogenicity of the RTSS in combination with antimalarial drugs in Thailand. Such novel approaches aim to extract the maximum benefit from the well-documented, short-lasting protective efficacy of RTS,S/AS01.
