This paper identifies determinants of domestic waste recycling and use in three swamp areas of Yaounde, Cameroon, based on data collected from 126 farmers between August and September 2005. Findings indicate that vegetable production, short farm-to-home distance, use of recycled livestock waste, education level, and farm surface positively influence the decision to use domestic waste. Conversely, farmer age has a negative effect.

This paper describes the development and impacts of urban agriculture, specifically "organopónicos," in Cuba. It highlights how this approach utilizes local productive potential and available labor to significantly increase agricultural products for the population. The impacts include contributions to human nutrition, providing vitamins, minerals, and plant/animal protein, and fostering new dietary habits based on societal possibilities.

Lei Yan-hua · · Australia

This paper discusses the state of therapeutic horticulture in Australia, describing the field as largely project-driven with little government or philanthropic funding to sustain long-term growth. It notes that recent initiatives in community gardens, school and children's gardens, and horticultural therapy services have expanded the scope of activity and, while still small compared with many other countries, are high-profile, community-led, and have secured significant government funding. However, the paper states that this needs to be balanced against numerous barriers facing the sector: insufficient research, limited organization and representation, few education and training opportunities, and a lack of outreach and community services.

S. Al-hassan · The IUP Journal of Agricultural Economics · Ghana

Using cross-sectional data from 196 urban agriculturalists (136 vegetable farmers and 56 non-vegetable farmers) in the Tamale Metropolitan Assembly, Northern Region, Ghana, a 2009 study examined the factors determining the decision to cultivate vegetables. Results showed vegetable production in the study area was influenced by extension services, use of inorganic fertilizer (manure), and availability of farmland. The study recommends training existing extension agents in modern vegetable production techniques so they can in turn train farmers, with emphasis on quality seed production, variety selection, diversification and quality control; directing extension services toward efficient manure application; encouraging vegetable farmers to form cooperatives to network with livestock producer associations; and having policymakers provide large, suitable irrigable land for vegetable production.

This paper discusses the characteristics of urban agriculture, the significance of linking agricultural universities with urban agriculture, and concrete measures by which agricultural universities can serve agriculture.

G. Palaniappan, Christine King · Queensland's institutional digital repository (The University of Queensland) · Australia

A conceptual paper framing local food production systems—termed "alternative farming"—against a backdrop of global environmental changes (retreating sea ice, landscape drying, shifts in seasonal timing and animal migration) and climate-driven increases in energy prices and dependence on fossil fuels, which the authors say have raised interest in localization and sustainability among communities worldwide. It examines systems including organics, natural farming, biodynamics, permaculture, community gardens, and community-supported agriculture (CSA) in terms of how they might contribute to localizing food production and consumption, and discusses the transition from globalized to localized farming and re-localization's ecological and social dimensions. The paper argues that sustainability can be grounded in local ecological, social, economic, and political systems, but the discussion is conceptual rather than based on presented empirical data.

Sinan Koont · Monthly Review · Cuba

An article describes the development, over roughly fifteen years since the 1990s, of urban agriculture in Havana, Cuba, a capital city of more than two million people. It notes that the term "urban agriculture" in Cuba is used more inclusively than typical usage, encompassing urban fringe and suburban lands — the entire cultivated area of the Province of the City of Havana is classified as urban agriculture. The article provides no specific yield or participation figures.

Masud Aziz Rauf · School for International Training Digital Collections (School for International Training) · Ghana (Tamale)

This research, conducted in the Tamale metropolitan area of Ghana's northern region, investigated the efforts of URBANET, a local NGO, to educate and involve indigenous farmers in advocacy as part of Ghana's broader trade justice movement. URBANET advocated for farmers facing challenges like falling prices due to imported products under unfair trade policies, providing workshops, radio programs, and mobilizing farmers. The advocacy raised awareness among indigenous farmers and contributed to policy changes, such as the Ghanaian government's 2005 statement requiring state institutions to buy Ghanaian rice.

This work explores the relationship between mental health and social space, examining various contexts. Chapters cover geographies of difference in mental health, community and citizenship, rural communities, and the therapeutic potential of urban gardening for citizenship and social inclusion. It also discusses artistic spaces and virtual communities in relation to mental health.

Stephan Barthel, Carl Folke, Johan Colding · · Sweden (Stockholm)

This thesis investigated how social-ecological features influence ecosystem service (ES) generation through case studies in Stockholm, Sweden. Findings indicated that urban ES flows are products of co-evolutionary processes, requiring governance to consider historical rights and diverse actor groups. Informally managed allotment gardens showed higher pollinator abundance compared to other urban green spaces, and social-ecological memory among gardeners was found to retain and transmit practices linked to ES generation. The study concluded that sustaining urban ES depends on management practices by people and local communities of ecosystem practice.

Friedhelm Streiffeler, Elsamawal Khalil Makki, Ali Ayoub · Econstor (Econstor) · Sudan (Khartoum)

This research in Greater Khartoum, Sudan, investigated urban and peri-urban agriculture as a livelihood strategy for internally displaced persons. While urban agriculture significantly reduces absolute poverty, its implementation faces many problems due to natural, economic, and social differences in the new environment, resulting in a low degree of agricultural development. Migrants with smaller fields and lower agricultural development showed a greater desire to return to their homeland, and social integration also influenced the decision to stay or return.

A study in Ghana used participatory research methods to summarize farmers' perceptions of health risks and risk reduction measures in urban vegetable farming irrigated with untreated wastewater. Farmers were aware of health risks from wastewater, perceiving occupational skin infections as the greatest risk, while consumer health risks were rated very low. Many international risk reduction measures were deemed unsuitable by farmers, who preferred simple, low-cost alternatives.
