This literature review explores the role of urban metabolism (UM) assessments in addressing food security through urban agriculture in informal settlements, particularly in lower-income countries. It addresses the challenges of food security in urban areas and aims to unravel existing urban dynamics and networks to generate agro-food resources in these settings. The review included a comprehensive search using the Scopus and Web of Science (WOS) databases to identify relevant studies. A total of 381 articles published between 2000 and 2023 were retrieved. Additionally, a systematic review of grey literature was performed using Google Scholar, focusing on publications in the Spanish language from the years 2000 to 2023 to address food security dynamics in Latin America as a key case study area. After screening titles, keywords, and abstracts, 127 journal articles from the Scopus and WOS databases and 51 results from the grey literature were considered for further analysis. Bibliometric coupling techniques, including co-citation analysis, co-occurrence analysis, and keyword analysis, were employed using VOSviewer software to visualize the scholarly landscape and identify major themes. The analysis of white literature facilitated the identification of six major themes: (1) UM and Sustainability; (2) Phosphorus Management and Recycling; (3) Food Security and Waste Management; (4) Material Flow Analysis and Environmental Impact; (5) Human Impacts on the Environment; and (6) Food Systems and Sustainability. The main findings pointed to the environmental and social sustainability impacts of food flows in UM studies, emphasizing the pertinence of UM as a conceptual framework to address urban sustainability and justice challenges, particularly in informal settlements. Additionally, the grey literature provided insights into community strategies, urban resilience, and social inequality, enriching the understanding of local realities and socio-economic dimensions related to UM and food security in informal settlements. The review showed that by incorporating UM approaches and circular economy strategies, it is possible to optimize flows and stocks within the agro-food systems, leading to improved food security, sustainable development, and enhanced resilience in urban environments.

“…Arguably, this rise is also linked to rising international support for a bioeconomy transition (especially as part of the EU strategy), laying a solid foundation for the pursuit of research questions on this subject. There were mixed reports on the effectiveness and efficient transformation of natural resources during this period (Asamoah et al 2020;Gmür 2020;Malisa et al 2019;Samson et al 2018;Reetsch et al 2020). Just as the number of papers, very few case studies were conducted in the late 1990s.…”

“…In East Africa (Ethiopia), Lowore et al ( 2018) reported effective product transformation, characterized by the semi-processing or primary processing of NTFPs into honey, including pyrolysis, the process used to produce charcoal from wood (Nabukalu and Gieré 2019). Farm waste in Tanzania is converted into bio-fertilizer (Reetsch et al 2020). In Malawi (Southern Africa), baobab fruits were reportedly processed into a variety of food and non-food products, such as fruit juice, ice-lollies, sweets, and cosmetics (Darr et al 2020), while there is semi-processing of honey in Zambia (Lowore et al 2020).…”

Nexus approach and environmental resource governance in Sub-Saharan Africa: a systematic review

2022

Sub-Saharan Africa (SSA) is replete with significant environmental resources including forests, water, land, and energy; although its transition to a bio-resource economy is yet to be actualized. Consequently, there are limited socio-economic gains from resource valorization. These challenges which stall progress towards the attainment of several interlinked sustainable development goals, are rooted, among others in resource governance defects. Furthermore, the persistence of knowledge fragmentation on resource governance shades possibilities for an in-depth theorizing of the nexus approach. In this light, two questions beg for answers: (i) To what extent are governance indicators captured in empirical studies on the nexus approach in SSA? (ii) What questions and approaches should inform future research on the nexus approach in SSA? To answer these questions, this paper systematically reviews 100 peer-reviewed articles (with 154 cases) that address governance questions in nexus studies within the broad framework of bioeconomy transitioning in SSA. Using the PROFOR analytical framework, our analysis reveals the following: (1) Although sub-regional variations exist in the application of nexus thinking, the overall emphasis in SSA is on first-level resource transformation. (2) With only 5% of studies explicitly mentioning the nexus approach, there is a strong indication for nexus thinking to be prioritized in future research. (3) While efficiency is the most recurrent in the literature (69%), its assurance in resource nexus and transformation is insignificant. (4) Interlinked questions of equity, participation, transparency, and conflict management have not been sufficiently addressed in studies on the nexus approach. The paper suggests an urgent need for in-depth, multi-country, and interdisciplinary research on these governance parameters in the nexus approach, as prerequisite to advancing the science–policy intercourse in nexus thinking in SSA.
