AbstractAccording to the Global Food Policy Report 2017, nearly 90% of the projected urban population increase by 2050 is going to be concentrated in Africa and Asia. Parallel evidence suggests that poverty and related challenges of food insecurity and undernutrition are also urbanizing. The dynamics underlying urban nutrition is different from rural ones but also arguably represents a more complex scenario. In this review, we synthesize available evidence on urban nutrition (in)security in the Global South. Although focused on nutrition-centric literature, our review also identifies and discusses studies in the contexts of the broader notion of urban food systems. Articles that analyzed any form of mal/nutrition were eligible for inclusion. One hundred sixty-nine articles were shortlisted based on a systematic search strategy, then expanded through a backward and forward literature survey. Our review identifies key emergent themes from a large body of research on urban food systems, noting that surprisingly few address nutrition directly. Rather, current literature on urban nutrition is scattered and skewed with an overt focus on urban agriculture. Our review reveals that the existing literature with direct nutrition relevance in an urban context can be systematically organized across three themes, i.e., urban agriculture, nutrition transition, and social protection. Noticeably, this literature also draws upon successful interventions having implications for urban nutrition. Finally, the review identifies a few research gaps that hinder a holistic view of urban nutrition. These gaps pertain to gender, equity, water (along with sanitation and hygiene), and local governance.© 2024. The New York Academy of Medicine.
