Applications Potential of Structural Path Analysis in Urban Agriculture: A Literature Review
2014Harry Kasumba, Tabukeli Musigi Ruhiiga · Journal of Human Ecology · Global
This literature review explored the potential of Structural Path Analysis (SPA) for investigating urban agriculture. The review found that urban agriculture has not yet attracted scholarship using the SPA technique. It also identified that smaller geographical areas often lack applicable databases for SPA, and a critical requirement for SPA is a developed system of continuous record-keeping by participants, which is often absent.

2014Zogo Ndomo, Yannick Emmanuel · Bulletin of animal health and production in Africa · Global
Urban agriculture in developing countries is a vital asset in the livelihood strategies of urban households, having expanded rapidly over the last two decades and contributing to income generation for unqualified workforces. However, the illegal status of urban agriculture has created a governance vacuum, necessitating policy formulation and institutionalized management to secure land for the urban poor and improve food security and the environment. Political leaders have a role in regulating this sector.

2014Amanda E. Nelson, Andrew A. Forbes · PLoS ONE · Global
This study sampled two plant-herbivore-parasitoid systems across 250 sites in a 360 km2 urban/agricultural landscape to investigate the impact of human development on trophic interactions. It found that herbivorous insect densities were decoupled from host tree densities in urban landcover types at several spatial scales. Furthermore, a parasitoid species was absent from all urban/suburban landcover in one system, even where its herbivore host was common, indicating that human land use patterns limit specialist insect distributions due to dispersal constraints.

2014Yuki Sampei, Yuji Hara, Akinobu Murakami, Armand PALIJON, Kazuaki Tsuchiya, Makoto Yokohari · Journal of The Japanese Institute of Landscape Architecture · Philippines (Metro Manila)
The nitrogen supply-demand balance in compost and vegetable production on vacant lots in suburban residential districts of Quezon City, Metro Manila, was assessed. Analysis revealed that almost half of the subdivisions faced nitrogen oversupply, while several were in short supply. Current centralized composting facilities may not adequately support a continuous compost recycling system due to their distribution patterns. It was proposed that existing barangay-based policies on organic waste management and urban agriculture require greater flexibility and attention to coordination systems across subdivision boundaries.

2014Kylie Markow, Sue Booth, Stephanie Savio, John Coveney · Nutrition & Dietetics · Global
This study compared perspectives of low socioeconomic individuals and food system representatives regarding access to community-based food systems. Focus groups with low socioeconomic individuals and interviews with food system representatives revealed that affordability, convenience, and knowledge were barriers. While representatives acknowledged these barriers, their understanding of importance differed, and views were divided on strategies, especially concerning affordability. A disconnect exists between the two groups' views on improving access for disadvantaged groups.

2014Abdirahman Osman Warsame, Fadumo Abdi Mohamud, Ahmed Hassan Ali · Zenodo (CERN European Organization for Nuclear Research) · Democratic Republic of the Congo (Kinshasa)
This scoping review synthesized evidence on the association between heavy metal contamination in vegetables sold in Kinshasa's urban markets, Democratic Republic of the Congo, and human biomarkers of consumer exposure. Available evidence consistently showed that vegetables, particularly leafy greens, from Kinshasa markets contained elevated levels of lead and cadmium, often exceeding international safety limits. However, studies directly linking vegetable contamination with human biomarkers are notably scarce, suggesting a potential exposure pathway but not establishing definitive causation.

2014Nicole C. List · EchoGéo · Senegal (Pikine)
Based on fieldwork in Pikine, a rapidly urbanized city in Senegal's Dakar region, two interconnected conflict cases concerning the development of urban agricultural land for middle-class and elite housing were analyzed. The analysis indicates that public and private actors, including producers, traditional authorities, real estate developers, and local/central government officials, are abandoning old forms of governance in favor of "territorial alliances" to promote their own urban development projects. These alliances lead to new relationships between local/central government members and civil society, impacting urban Senegal's land registry, property rights, and public infrastructure.
