Georgia Pollard, James Ward, Philip Roetman · Sustainability · Australia (South Australia)

This paper explores the economic sustainability of home food gardens in South Australia using new data from the Edible Gardens project online survey. While saving money is a top motivation for many respondents, the study notes that it remains to be seen whether current gardening practices actually support this aspiration. The paper concludes that more work is needed to measure the full costs of different gardens to better predict their financial accessibility and economic sustainability.

This study in Accra Metropolis, Ghana, compared Anopheles gambiae s.l. species composition and insecticide resistance between two vegetable-growing and two non-vegetable growing areas. All A. gambiae s.l. populations tested were resistant to five insecticides, with lower mortalities observed in vegetable-growing areas (e.g., 2.6% and 12.5% for deltamethrin) compared to non-vegetable areas (36.2% and 38.9%). Anopheles gambiae s.s. and Anopheles coluzzii were dominant in vegetable-growing areas. The findings indicate that urban agriculture contributes to the development of insecticide resistance, which needs consideration in vector control strategies.

Kota OGUCHI · The Annals of Japan Association for Urban Sociology · Japan (Saitama City)

This article studies the impact of coordinators for Community-Supported Agriculture (CSA) programs, using the Kome Mame project in Saitama City, Japan, as a case study. The Kome Mame project is a collaborative effort involving organic farms, a for-profit company, and an NPO, where the NPO coordinates matchmaking between farmers and companies, builds mechanisms for distribution channel development, and facilitates human-resource exchanges and stakeholder relationships. The study suggests that the coordinator's role as a manager of the relationship between food and agriculture will become increasingly important, and the challenge is whether this role can be established as a socially recognized profession.

Solomon Tulu Tadesse, O. Oenema, Christy van Beek, Fikre Lemessa Ocho · Nutrient Cycling in Agroecosystems · Ethiopia

This study investigated the diversity and nutrient balances of urban and peri-urban agriculture (UPA) systems in three Ethiopian cities, using data from 425 households (Addis Ababa: 175, Adama: 126, Jimma: 124). It identified six farm types, including commercial livestock (cLS) and subsistence field crop (sFC) systems. The study found that cLS systems accumulated significant nutrients (450 kg N, 85 kg P, 260 kg K ha−1 year−1) with low use efficiency (26% N and P, 15% K), while sFC systems depleted nutrients (−30 kg N, −17 kg K ha−1 year−1) with high use efficiency.

Dissolved phosphorus (PO4 3-) and nitrogen (NO3- & NH4+) losses in leachate from experimental raised-bed garden plots were measured. Plots receiving cow manure compost showed high PO4 3- concentrations (5-11 mg/L), while municipal organics compost plots had concentrations an order of magnitude lower (0.5-1.2 mg/L), and no-compost plots had 0.3 mg/L. Phosphorus lost through leachate and harvest accounted for only 1-10% of total applied phosphorus, indicating soil build-up was the dominant fate. This study illustrates a potential trade-off in urban agriculture between crop production and efficient phosphorus recycling from urban food waste.

Ayinde BA, Nicola Cantoreggi · International Journal of Environment Agriculture and Biotechnology · Senegal (Dakar)

This study focused on the commercial dimension of urban and peri-urban agriculture (UPA) in the Dakar region, Senegal, involving 214 market gardeners across three production areas. Results showed that UPA, specifically urban market gardening, constitutes a full-fledged commercial activity with monetary income significantly higher than Senegal's minimum wage. This almost exclusively commercial orientation allows agri-urban households to cover their food and non-food expenses inherent in urban living.

Silverio Hernández Moreno, José Antonio Hernández Moreno, Bianca G. Alcaraz Vargas · Cuadernos de Vivienda y Urbanismo · Mexico

This article proposes an urban cluster for planning low-carbon cities in Mexico, drawing on environmental design models for buildings and smart city planning strategies integrating urban and rural land uses. It suggests allocating areas for urban agriculture and alternative energy generation, in addition to housing, commerce, and green spaces. The cluster design is concluded to function as an urban design pattern, useful for smart city planning, and a reference point for planning "ruracities."

Bolanle Wahab, Ayobami Abayomi Popoola, Hangwelani Hope Magidimisha · PLANNING MALAYSIA · Nigeria (Ibadan)

A study in Ibadan, Nigeria, investigated urban farmers' access to land and local planning authorities' land allocation activities, using questionnaires with 244 urban farmers and key-informant interviews. Rapid, unplanned urban growth limited farmers' access to land, with over 30% farming on family land and 17% on open spaces like floodplains or under power lines. Barriers included land unavailability, finance, and land tenure system issues.

Tal Alon‐Mozes, Efrat Eizenberg · · Global

This chapter examines Mediterranean urban agriculture (MUA) through case studies, challenging the traditional division between developed northern and developing southern countries. It argues that MUA is a distinct phenomenon characterized by the transfer of modern agricultural knowledge and policies from developed to developing countries, alongside a northward movement of people, crops, and traditional lifestyles from the south.

Solomon Gbanie, Amy Griffin, Alec Thornton · Remote Sensing · Sierra Leone

This research analyzed land cover change (LCC) dynamics in Sierra Leone's Western Area from 1976 to 2011 using satellite imagery, covering pre-conflict, conflict, and post-conflict periods. The study found a rapid increase in built-up land and urban/peri-urban agriculture over 35 years. During the war (1976-2000), urban agriculture became a key livelihood for displaced persons, while post-war housing demands further drove land use changes. A significant finding was that landscape fragmentation increased alongside declining forest cover, with built-up areas aggregating.

Patricia Noto · Digital Commons - RISD (Rhode Island School of Design) · United States (Providence)

This thesis investigated the role of designers in creating or enhancing productive systems in cities, focusing on Providence, Rhode Island. It proposed rethinking the function of public and quasi-public spaces and expanding the definition of urban productivity beyond community gardens to include a network of agroforestry sites and remediated lands. The study examined a series of diverse sites along the Woonasquatucket River, noting their suitability due to the river's industrial history, varied conditions, and existing community organization connections.

This qualitative field study in two cities in Piauí, Brazil, evaluated whether working conditions of urban and peri-urban agricultural producers contribute to food production. It concluded that public authorities' participation is necessary to address failures in the small-scale agricultural production system and improve working conditions for urban horticulturists.

Paloma Gonzalez de Linares · International Journal of Design & Nature and Ecodynamics · Hungary (Budapest)

This paper aimed to assess factors contributing to more successful integration of urban agriculture in some cities and to introduce agro-ecology practices in public green spaces and community gardens through landscape assessment and map-based comparison. A key problem identified was the lack of motivation among planners to integrate urban agriculture into urban plans, preventing these green structures from becoming part of the city's landscape and dynamics. The sustainability of food systems was concluded to depend on the city's planning strategy and governance policies.

Jaime Hernández García, Sandra Caquimbo-Salazar · · Colombia (Bogotá)

In Bogotá, Colombia, over 50% of the city has developed through informal practices, with approximately four million people residing in areas of urban or housing informality. This chapter explores the transformation and appropriation of urban spaces in the barrios through urban agriculture initiatives, using examples of food growing spaces in Bogotá. It discusses agricultural practices in the city's informal settlements, highlighting social characteristics and spatial particulars, and advocates for open spaces as potential productive landscapes where spatial transformations can contribute to social, cultural, and nutritional practices.

Sécou Omar Diédhiou, Oumar Sy, Christine Margétic · Espace populations sociétés · Senegal (Ziguinchor)

A study in Ziguinchor, Senegal, surveyed 248 farmers and 130 vegetable vendors in 2016 and 2017 to examine the role of urban agriculture. Urban expansion has led to shrinking agricultural land and land-use conflicts, while increasing food demand. Women play a central role from production to commercialization, farming in multiple locations for self-consumption and income, but the sustainability of these practices requires integration into proactive urban development policies.

Mohammad Rondhi, Pravitasari Anjar Pratiwi, Vivi Trisna Handini, Aryo Fajar Sunartomo, Subhan Arif Budiman · Land · Indonesia (East Java)

This paper investigated the inter-relationship between land economic value and agricultural land conversion (ALC) in East Java, Indonesia. It calculated the land economic value for agricultural and non-agricultural (housing) uses in two areas: a peri-urban agricultural area facing rapid urbanization and a rural agricultural area with zero ALC. Results showed that agricultural land yielded a higher economic benefit in rural areas, whereas in urban areas, housing yielded a value seven times higher than agricultural land.
