Poverty elimination by 2030 is the major initiative of the United Nations Sustainable Development Goals. However, poverty in Sub-Saharan Africa is rising. There is an absence of structural reform for transformational change across the region. E-commerce is an enabler of small and large businesses in developed economies. Community-led initiatives for poverty alleviation may benefit from the transactional capabilities of e-commerce for direct trade with suppliers and consumers. Well-structured small and medium-size enterprises (SMEs) can foster local innovation and entrepreneurship, and collaboration between SMEs can enhance product development and marketing strategies. This review aims to discover formal research into the application of e-commerce in sustainable development models for poverty alleviation in Sub-Saharan Africa, and the extent of innovation, entrepreneurship, and collaboration among SMEs. The review found an absence of formal research into theories and practical strategies for sustainability innovations across the low-income spectrum. Organizational structures have not been developed to stimulate outreach, to foster innovation and entrepreneurship, or to embrace technology. Further, there is limited discussion on the importance of collaboration for the sharing of knowledge and joint business activities, but there is acknowledgement that SMEs can provide spatially diversified sustainable development. This article proposes a framework for the implementation and management of networks of SMEs focused on the sustainable development of low-income communities.

Low-income urban and rural communities in Sub-Saharan Africa are habitats for more than 556 million profoundly poor people, and the United Nations and the African Union are pessimistic that sustainable development goals will be met. The number of people falling into poverty is increasing, and policy initiatives to reduce poverty have been confounded by various economic, political, social, structural, and environmental issues. Despite a wealth of natural and human assets, there is no systematic approach to sustainable development for poverty alleviation in Sub-Saharan Africa. This case study of an urban community in Ghana, West Africa, investigates the potential role of digital twins in a systematic approach to sustainable development for poverty alleviation. Aerial and community surveys of the built environment and social and economic surveys of businesses and households were compiled to inform a virtual representation of the study area. A small e-commerce business intervention was introduced, and data was recorded for studies on the impact of the intervention. A 3D interactive view, extensive video, and fixed images provided a comprehensive view of the built environment. A limited view of the social and economic environment was obtained from a small population sample. It was observed that online transactions increased in the businesses receiving the e-commerce intervention, demonstrating a willingness of businesses and their customers to engage in e-commerce when incentives are provided. A single successful community-centric initiative has little value unless it can be generalized across the broader society. This limited case study focused on developing and testing virtual and physical constructs to enhance a deeper understanding of the community, community engagement, and pathways to sustainability. The scale of the intervention was too small to conclude generalizability. Future research will focus on improving the data collection processes, fidelity of virtual representations, visualization methods, and methodologies for constructing viable virtual interventions.

Sub-Saharan Africa is currently experiencing growth in the number of people living in poverty, and the situation is worsening due to climate change and the COVID-19 pandemic. Cities are increasingly under stress because of urbanization and the demand for low-cost housing. Slum dwellers face daunting social, environmental, and economic challenges. Geospatial analysis of remote sensing, demographic, economic, social, and environmental data is being used to delineate slums. The application of circular economy guidelines for an intelligent transformation of slums combines technical and social innovation that reaches beyond the slums to the whole urban ecosystem. Examples of contributions to the circular economy are provided. Finally, some ideas are introduced on how the internet of things can improve access to goods and services and strengthen interconnectedness through the ability to participate more readily in the social dialogue of the city. The city of Accra in Ghana, West Africa, is discussed as a potential slum city to functional intelligent city transformation.
