A qualitative study in Zimbabwean slums in Tanzania, involving semi-structured interviews with 20 participants from four communities over six months, explored the impact of community gardening. Participants reported significant improvements in mental health scores, noting an enhanced sense of purpose and social connection. Community garden programs appear to be a promising low-cost intervention for improving mental health resilience among urban slum dwellers.

This study determined horizontal fluxes of N, P, K, and C, and gaseous N and C emissions in two urban vegetable gardens in Bobo-Dioulasso, Burkina Faso, from March 2008 to March 2009. Emission rates peaked after fertilizer applications during hot midday hours, with annual gaseous N and C losses reaching 419 kg N ha−1 and 35862 kg C ha−1 at Kodéni, and 347 kg N ha−1 and 22364 kg C ha−1 at Kuinima. Ammonia emissions accounted for 73% and 77% of total estimated N losses, suggesting that nutrient management practices could benefit from better synchronizing nutrient-input rates with crop demands.

A qualitative study in Tunja, Colombia, designed, implemented, and evaluated an intervention strategy to increase vegetable availability in a community. Applying five principles of community-based research, the strategy included educational and urban agriculture components. Seven participatory educational sessions were conducted, and eight home gardens and one community garden were implemented. The intervention strategy successfully increased vegetable availability, fostered community empowerment, built social networks, and highlighted the role of nursing professionals in community actions.

This mixed-methods study analyzed the development of school garden initiatives by tracking the progress of 55 primary schools participating in the "Food for Life Partnership" program. Findings showed considerable expansion of food growing facilities, outputs, and supporting infrastructure. Participating students, parents, and community volunteers created new links to food-related activities in the dining hall, classroom, and home environment. The effectiveness of these changes was connected to the strategic redevelopment of growing spaces and conceptually integrated messages on food sustainability.

This article examines the concept of "translocal citizenship," which moves away from the nation-state as its territorial reference point and rejects its continuation within new supranational entities. The second part focuses on the "Beyond a Construction Site" project, initiated by the Obrat Culture and Art Association (KUD Obrat), where an unused construction site has been repurposed as a community garden. This project practically illustrates translocal citizenship by fostering new forms of collective action and political membership better suited for intercultural dialogue and the inclusion of migrant communities.

Fungai Hamilton Mudzengerere · · Zimbabwe (Bulawayo)

This research investigated the contribution of women to food security and family livelihoods through urban agriculture in Bulawayo, Zimbabwe. Primary data collected through observations and interviews showed that women practice urban agriculture more than men and play a crucial role in household food security. While women make decisions on crop types, harvest times, and markets, they face challenges with land ownership, financing, and market access, which negatively affect their agricultural activities.

This article examines the changing demand for allotment gardens and the motivations of plot holders, refuting the assumption that economic reasons are primary. It finds that while allotments have historically alleviated hunger, the social aspect primarily motivates most plot holders. Allotments are valued by individuals and collectives as part of history and cultural heritage.

Marielle Dubbeling, H. de Zeeuw · Edward Elgar Publishing eBooks · Global

This handbook highlights that most urban growth occurs in less developed regions, often leading to over-urbanization where migrants struggle to find employment, adequate shelter, and sufficient food. Despite these challenges, urban poverty is frequently considered less severe than rural poverty.

This paper discusses how urban agriculture improves the economic situation and health of poor and vulnerable families in both industrialized and developing countries. It suggests that policies reconciling urbanity and rurality can reduce food insecurity and better integrate the most vulnerable populations, contributing to sustainable development.

Olufunke Cofie · · Ghana (Accra)

This study examined the gender dimensions of livelihood sustainability through urban agriculture among vegetable producers in and around Accra, Ghana. Responses from 92 male producers and 8 female producers were analyzed, revealing a mean age of 39.4 years for males and 49.8 years for females, indicating females were older. The mean years of schooling were 6.4 for males and 7.1 for females. Urban agriculture significantly contributed to livelihoods, with farm size and access to credit identified as important determinants of income from urban agriculture.

Urban agriculture in Kinshasa, Democratic Republic of Congo, serves as a palliative solution for social survival constraints such as a lack of remunerative salaries and sustainable jobs. However, poorly supervised urban farmers cultivate along busy roads, exposing vegetables to various contaminations, including lead. This practice highlights issues with site selection and supervision.

A literature review examined the use of school garden programs for health promotion among elementary school youth. The review found that school gardens successfully improved academic achievement, increased fruit and vegetable consumption, and enhanced social skills. However, significant barriers to implementation were identified, particularly in low socioeconomic status schools, including a lack of funding, insufficient gardening knowledge among teachers, and limited community and parent involvement.

Nyumbaiza Tambwe, Michael Rudolph, Ran Greenstein · Africa · Democratic Republic of Congo (Lubumbashi)

A study was conducted in Lubumbashi, Democratic Republic of Congo, from November 2004 to March 2005, on 100 farming households that adopted urban agriculture as an alternative livelihood after the collapse of a mining company. Data collected through semi-structured interviews, in-depth questions, and observation revealed that despite practicing urban agriculture, the living conditions of 75% of households declined, and 20% stabilized their living conditions but could not completely alleviate poverty. Only 5% of farmers achieved food security.

Using household survey data from 15 developing countries, this seminal study analyzes urban agriculture's contribution to poverty reduction and food security among the urban poor, finding it is mostly own-consumption oriented and offers modest but real welfare benefits.

Geoffrey Ross Owens · Africa · Tanzania (Dar es Salaam)

This article, using ethnographic and historical approaches, examines unplanned peri-urban settlements on Dar es Salaam's northern and western fringe, Tanzania, between 1975 and 2000. These districts were established by educated urban professionals who used urban farming as an economic diversification strategy. The study found that these settlements contributed to the reproduction of socio-economic inequality, attracting additional economically influential urban in-migrants after 1991.

Urban and peri-urban agriculture (UA) significantly contributes to the total food requirements of cities, especially in southern cities of the developing world. This review describes agronomic issues unique to UA and identifies possible interventions to address them. Growth-limiting and growth-reducing factors in UA include water availability, nutrient supply, soil degradation, pests, and soil pollution. Addressing these constraints requires action at both field and municipal or regional levels.

This paper analyzed the impact of armed conflicts on urban livestock keeping, particularly small ruminant keeping, in Brazzaville, Republic of Congo. Two surveys, one before 1993 and one after 2002, indicated that the 1997 conflict had a negative impact on livestock keeping, as most livestock keepers lost their animals. Financial resources were an important factor in rebuilding the flock after 1997.

A review of urban agriculture in Zambia's four largest cities revealed that despite attempts by the Kaunda government in the 1960s–1970s to create supportive policies, there is currently a near absence of institutional support, constraining farmers' activities. A survey of 400 farmers confirmed the value of urban agriculture as a survival strategy but also highlighted the lack of necessary support measures.

This reflection on the urban agriculture movement notes that 19th and early 20th-century urban reforms, including urban gardens, aimed to improve living conditions in industrial cities. However, these initiatives also shifted the burden of sustenance from industrialists and fair-wage policies onto urbanizing families, particularly women. Despite this, garden spaces provided nourishment and retreats in densely populated areas.
