A Systematic Literature Review on Local Sustainability Assessment Processes for Infrastructure Development Projects in Africa

Reviews on sustainability assessment research have shown that Africa is lagging in this research area. As a result, few African countries have local sustainability assessment processes for infrastructure development. Considering the vital role of infrastructure to Africa’s development, the identification of only a few countries with local sustainability assessment processes raises questions on the overall state of sustainability assessment in the continent. To date, there is no study that gives a definite account of which African countries have local sustainability assessment processes for infrastructure. The aim of this study was to conduct a systematic literature review to identify and analyze local sustainability assessment process for infrastructure development in an African country. Using PRISMA to guide the review process, the study showed that six processes have been created for infrastructure development in Africa. The African countries with these processes are Egypt (three), Nigeria (one), Malawi and Kenya (one) and South Africa (one). The results showed that the sustainability assessment process correspond to most of the Sustainable Development Goals (SDG) targets with social and economic considerations taking the lead in the processes created for energy and transport infrastructure development projects, whereas the sustainability assessment processes created for water supply, waste and communications infrastructure development projects have a balance of social, economic and environmental sustainability considerations. The review has revealed a need to create energy, transport and water supply infrastructure sustainability assessment processes that address current sustainability concerns such as climate change, social justice, equity, fairness and equality.
