Current urbanization trends and projections clearly indicate that the global South cities, especially of Asia and Africa, would be at the receiving end of about 80% of the expected 2.7 billion increase in urban population between 2010 and 2050. These trends and projections make it imperative for the future planning of the global South cities to step out of the box, away from the traditional planning systems, and begin to adopt inclusive and innovative planning approaches that would efficiently tackle the current and emerging urban realities in these cities rather than sticking to rigid planning standards that ignore realities, generate continuous conflict, and fail to take advantage of the potentials of these urbanization consequences, especially the resilient informal economy. The chapter examines the urbanization trends and one of its major challenges in global South cities; informal economic activities, the planning implications of these informal economic activities, various approaches that have been adopted by different governments and the effectiveness or otherwise of the approaches in tackling the challenges of informal economy. The chapter also focuses on the successful planning approaches that have been implemented with a view to portraying the key lessons that can ensure its applicability in other global South cities facing similar challenges.

One major manifestation of rapid urbanization and underdevelopment is the re-emergence of informal sector activities. This trend includes the escalating growth of informal economic activities, among which are home-based enterprises (HBEs) in urban residential neighborhoods. This type of informal development, mostly undertaken by low-income urban residents, has defied government attempts to set standards or enforce compliance and is therefore a challenge for urban planners. There is a need to reconsider HBE activities in light of their positive contributions, which offset their negative effects on urban space. This paper draws urban planners’ attention to urban land use patterns and the alternative planning directions HBEs are prompting. It then calls for further research on how urban planners could plan and redesign the urban space with appropriate consideration of HBE operators. This paper has implications for national economies, especially in African and other developing countries.

A major challenge of urbanization in the global South has been the unemployment-led informal economy that has grown beyond the capacity of African governments in general and urban planners in particular. The socio-cultural status of women, and other inequalities in largely patriarchal African societies, have caused them to resort to the most invisible and adaptable sub-sector of the informal economy: Home-based enterprises (HBEs). This study examines the contributions and challenges for women in HBEs using empirical evidence from Enugu, Nigeria. The study employed mixed methods and made use of both primary and secondary data. The study findings confirm that HBEs provide economic succour to women excluded by the formal sector. Among the benefits of HBEs are income provision, supplementary household income, provision of goods and services, skill acquisition, social value and self-esteem, and the ability to look after sick family members. The challenges of HBEs were inconsistency and noise effects as reported by non-operators, while operators complained about multiple levies collected by government agencies, poor infrastructure, and insecurity.

Home-based enterprises (HBEs), which involve the use of one's residence for commercial activities, have become a prominent research focus in the fields of entrepreneurship, sustainability, and environmental management. Despite this, the lack of data impairs the ability to accurately evaluate the economic merits of this rapidly growing business model relative to its environmental effects. This article, detailing data on the demographic features of HBE operators in Ikot-Ekpene, Akwa Ibom State, Nigeria, contributes to ongoing data mining efforts towards realistic framing of HBEs. The current data represent HBEs from five Ikot-Ekpene neighborhoods: Uruk-Uso, Ifuho, G.R.A, Ibiakpan Akanawan, and Ikot Ekpene Urban. The target population of the survey included operators of HBEs and residents. A total of 400 questionnaires were issued through systematic random sampling across the five neighborhoods. The entire sample yielded 330 valid responses, which underwent a descriptive statistical analysis, compiled, and presented in tables and bar charts. Analysis of the data provided insight into the rating of the economic relevance of HBEs in relation to their associated environmental impacts. These data provide helpful insights for researchers and policymakers involved in regulating and controlling activities in the urban sphere. They also serve as a reference point for more rigorous studies on environmental management and urban informality in cities.

Most cities in the global south have evolved overtime with significant organic changes in their wake. One of the noticeable changes is the emergence of pockets of city-based agricultural activities, a previously rural-based activity. There are varying interpretations behind this new trend. With increased agglomeration arising from rural-urban migration, residents resort to farming as a panacea to urban challenges. Even employed urban residents resort to agriculture for supplementary income. This emerging scenario has generated debates, dialectics, and polemics among stakeholders as to the propriety or otherwise of this development. This chapter, therefore, takes a panoramic view to all the sides of the issue through review scoping of desktop research method. Specifically, it examines the scope of increase in urban agriculture (UA), the types and nature of UA; urban planners’ attitude towards UA, and then propose the management strategies such as promoting agriculture-friendly urban plans for access to agricultural land and practices. The findings revealed that UA takes place on residential land, undeveloped private/public lands, and riverbanks. The prominent UA activities are animal husbandry, aquaculture, cultivation of food and cash crops, etc. The urban-planning measures for integrating UA into the urban environment include inculcating UA-responsive policies in broad plans.
