In terms of the 2030 Agenda for Sustainable Development and the United Nations (UN) Sustainable Development Goals (SDGs), sustainable cities and communities (SDG 11), combined with good health and wellbeing (SDG 3), are vital. The world is not making adequate progress in meeting the UN's targets to address food security (SDG 2). In South Africa, the growing population, rapid urbanization, poverty, and unemployment exacerbate the issue of food security; even more so considering climate change (SDG 13). The built environment needs to respond to these demands and incorporate green initiatives that can provide ecosystem services. Novel approaches are required to optimize land use and promote sustainable built environments through food production. This paper consolidates literature on local vertical urban food production with vegetable crops to enhance ecosystem services and lower the carbon footprint of buildings in the Global South. The literature review points to the potential of small-scale edible living walls that utilize local materials and traditional African vegetable (TAV) species to enhance system sustainability and resilience. TAV species offer advantages as opposed to exotic food crops as they are tolerant to extreme heat and drought, have a high nutritional value, and have low irrigation and agrochemical maintenance requirements.http://iopscience.iop.org/journal/1757-899Xam2023Architectur
