In Kinondoni Municipality, Tanzania, a study assessed the types of integrated urban agriculture (IUA) practiced, livelihood strategies adopted, and IUA's contribution to household income. Quantitative and qualitative data were collected from 132 respondents, showing IUA to be the most prioritized livelihood strategy. 98.5% of farmers concentrated on crop-livestock integration, and the average annual income from IUA was 2,295,288 TSH (1093$), sufficient for a six-member household above the monetary food poverty line. This study focused solely on the income livelihood indicator, not considering other benefits like food security or social inclusion.

T.A. Lyson C.C. Geisler, Charles A. Schlough · · United States (New York City)

In New York, Community Supported Agriculture (CSA) expanded from non-existent 10 years prior to 64 farms by 1996. These efforts have the potential to foster local economic development and maintain product diversity and quality. Increasing local food and agricultural product production and marketing can preserve farmland that might otherwise be unprofitable for the global marketplace, integrating it into the local community. This shifts decisions about local farmland from global market forces to local farmers and consumers.

This survey identified necessary efforts for developing urban agriculture potential in the Palu River area, Palu City, Indonesia, a location considered suitable for urban agriculture due to the city's green city aspirations and potential population increase from a Special Economic Zone. Based on observational data and descriptive analysis, the study found that efforts should include land consolidation, activity type determination, recruitment and human resource development, infrastructure and facility preparation, and sustainable management.

Michael Tuffour · AgEcon Search (University of Minnesota, USA) · Ghana

This study in the Greater Accra Metropolitan Area, Ghana, investigated how urban vegetable farmers adapt to rapid urban change, using a mixed-methods approach including a survey of 251 farmers. Institutional actors promote urban agriculture through training, logistics, and land provision, but the changing urban environment hinders their support. Institutions providing land often lack official agreements with farmers and sometimes abuse them, despite being a significant support source.

Hayford Mensah Ayerakwa · International Development Planning Review · Ghana

A study using data from two medium-sized cities in Ghana analyzed the importance and determinants of food transfers received from urban or rural households. It examined whether participation in agriculture reduces a household's likelihood of receiving food transfers, showing that households participating in urban agriculture had a lower chance of receiving food transfers from other urban dwellers. Female-headed households and aging household heads had an increased likelihood of receiving food transfers, with grains and tubers being the most commonly received food groups, typically from rural and urban relatives.

In Niiza City, the development of processed local vegetables is not advanced. This research matched the needs of Niiza City with the seeds of a university, leading to the industry-government-academia collaboration for the development of a "carrot dressing" using Niiza City's certified autumn-winter carrots. Students from the Department of Food and Nutrition were involved from cultivation to prototyping and design, resulting in manufacturing in March 2017 and sales in April through collaboration with local companies.

Daniela Adil Oliveira de Almeida, André Ruoppolo Biazoti · Cadernos de Agroecologia · Brazil

This paper systematizes recent thoughts on agroecology and urban agriculture from important events in Brazil's agroecological field. It presents three approaches: "agroecology for the city," "agroecology in the city," and "agroecology of the city." These approaches connect the themes to different conceptions of the urban-rural relationship and suggest various research paths linked to transformative political action.

Jenny Smart, David Tschirley, Francis Smart, Smart, Jenny Cairns, Tschirley, David, Smart, Francis · AgEcon Search (University of Minnesota, USA) · Mozambique

Food system transformation and changes in diet quality were assessed in Mozambique amidst rapid urbanization and income growth. Rising incomes and processed food consumption were found to be associated with a worsening of negative dietary factors. Furthermore, urbanization, controlling for income, was more strongly associated with a worsening of negative factors than an improvement in positive dietary factors. However, owning one's own farm had a positive and significant effect on nutrition for urban households, primarily driven by reduced purchases of unhealthy foods.

Désiré Jean‐Pascal Lompo, Emmanuel Compaoré, Michel Papaoba Sédogo, Martina Melapie, Charles Bielders, Eva Schlecht, Andreas Buerkert · Nutrient Cycling in Agroecosystems · Burkina Faso (Bobo Dioulasso)

This study investigated nutrient management in six urban vegetable gardens in Bobo Dioulasso, Burkina Faso, quantifying nitrogen (N), potassium (K), and carbon (C) fluxes and balances. Inputs of N and K significantly exceeded recommended amounts, leading to substantial horizontal annual surpluses of 1013 kg N ha−1, 879 kg K ha−1, and 25 t C ha−1. While total balances for N and K were positive, the total balance for C was negative, indicating an environmental tradeoff due to excessive nutrient input.

Joyce-Ann Syhre, Meike Brückner · · Kenya (Nairobi)

This chapter illustrates agricultural alternatives in Nairobi, Kenya, emerging through practiced urban agriculture. These alternatives enable socio-ecological spaces of food sovereignty, biodiversity, and agency. The chapter discusses the socio-cultural values of farming and food, the role of gender in Nairobi's urban agricultural landscape, and the diverse perceptions of human-nature relations among female farmers.

This paper addresses the use of underutilized urban land for agriculture, noting that such land incurs significant financial and social costs for public infrastructure, maintenance, and cleanliness. It aims to explore how urban agriculture can contribute to building and qualifying the urban landscape.

Ryo Kawabe, Hiroshi Sakazume · Institutional Repositories DataBase (IRDB) · Japan (Nagakute City)

This paper analyzes the importance of social capital in the sixth industrialization of urban agricultural areas, using a case study from Nagakute-cho (now Nagakute City), Aichi Prefecture, Japan. The study found that the sixth industry is an efficient strategy for managing and demonstrating the multiple functions of urban agriculture, farm villages, and agriculture itself, with social capital being a crucial driving force. Nagakute City's initiatives, based on the "Countryside Valley Initiative," were successful, leading to the emergence of an integrated form of social capital combining government-led bonding with bridging among various local residents.

This study addresses the growing social interest in cultivating plants indoors for mental and emotional well-being and environmental improvement, particularly in South Korea. While research on selecting native plants and cultivation environments for urban agriculture is ongoing, studies on indoor cultivation of medicinal plants are scarce. Most medicinal plants are typically harvested from the wild or grown outdoors, unlike other horticultural plants.

Kwaku Obosu-Mensah · · Global

This chapter reviews literature to identify the types of people likely to engage in urban agriculture. It explains that the labor-surplus, dependency, and cultural lag models are complementary in explaining urban residents' involvement in agriculture. Low salaries compel workers to supplement income through urban agriculture, and the sector is expected to grow with population increases, notably with the increasing entry of highly educated and skilled personnel.

Katinka Mihova · · Global

This paper discusses urban agriculture as a sustainable future, particularly for the urban poor in developing countries. Defined as an industry within or on the fringe of urban areas that produces and distributes diverse food and non-food products, urban agriculture functions as an informal food supply system. The paper notes increasing global attention to urban agriculture and the emergence of analyses attempting to systematize its benefits and drawbacks.

Michael Carolan · Rural Sociology · United States

Understandings of "social justice" and "autonomy" were investigated among conventional corn producers in North Dakota and participants in an urban agriculture cooperative in an anonymized U.S. city. Qualitative interviews and "word cloud" analysis revealed greatly differing understandings of these concepts, but both groups were grounded in a shared neoliberal world that negatively impacts both populations. Interviewees in the rural space failed to understand their marginalization as an artifact of the neoliberal worldview.
