The way people access food in Nigeria is of central relevance for food security, health and sustainability. One key trend is the shift from household-based to primarily out-of-home food consumption as an increasing majority of the urban poor derive their daily nutrient intake from street foods. However, few studies have yet explored the role of the ready-to-eat food vending sector in urban food systems and the diets of the urban poor. This paper investigates the interrelations between these practices and the diversity of food groups provisioned among the urban poor in developing city contexts. A social practice approach is employed to explore differentiation among informal-ready-to-eat food vending practices in the city of Ibadan, Nigeria, in terms of their daily activities, competences and resources. Applied methods include GIS mapping, food log diaries, in-depth interviews and participant observation to map and classify informal-ready-to-eat food vending practices according to the nature of food provisioned and explore the everyday performances of different informal-ready-to-eat food vending practice initiatives and their relation to dietary diversity. The results reveal three key categories among these practices: traditional, processed and unprocessed—with varying levels of diversity in the food groups on offer. Traditional food vendors offer more diversified food compared to processed food vendors and unprocessed food vendors. The results reveal that material infrastructure, cooking bargaining and purchasing skills and nutritional knowledge are key to the diversity of food groups provisioned. The paper concludes by considering the wider relevance of these findings for urban food science and policy.

Although indigenous forest management practices have been used effectively by local people in the management and conservation of forest resources, these practices are eroding, causing negative consequences on the welfare of the people and their forests. To stem the erosion of the indigenous practices and instead stimulate, preserve, or improve their use, this study determines the socioeconomic factors that drive the household's use of the practices in the management and conservation of plant species of non-wood forest products (NWFPs). The study was carried out in Nigeria derived savannah. Data was collected from 200 randomly selected households in 10 randomly selected forest communities. Multivariate probit model was used to estimate the socioeconomic factors that influence the simultaneous use of indigenous forest management practices by households. Given multiple use of the practices, the result shows that the indigenous forest management practices used by the households are selective weeding (82.98%), controlled harvesting (82.45%), enrichment planting (75.53%), fire breaks (76.06%) and indigenous protective mechanism (45.74%). The majority (71.28%) of the respondents said they managed bush mango (Irvingia gabonensis and wombulu) using the practices, while the lowest proportion (21.28%) managed bush buck (Gongronema latifolium). The result of the multivariate probit model shows that virtually all the indigenous forest management practices are positively and significantly associated and are thus, complements. However, local protective mechanisms and controlled harvesting, local protective mechanisms and selective weeding, and local protective mechanisms and enrichment planting are not significantly associated. Farming occupation significantly increases the likelihood of simultaneous use of controlled harvesting, enrichment planting, and fire breaks as indigenous forest management practices in the management and conservation of NWFP. On the other hand, age significantly reduces the likelihood of the use of controlled harvesting and selective weeding. The study recommends the provision of support for young people who are more likely to be involved in the indigenous forest management practices; support to farmers who simultaneously use the practices, for example, through the provision of credit facilities; and a proper definition of user rights in community forests.
