A study of peri-urban families in Ciudad Cardel, Veracruz, Mexico, measured dietary diversity using a staple-foods scoring method and assessed eating habits and willingness to practice home horticulture using a Likert-scale survey. Thirty-five percent of households showed good eating habits, 19% regular, and 46% poor eating habits. Dietary diversity scored 29.4 ± 8.7 for staple foods. The general Likert index for willingness to practice horticulture was 2.9, indicating average availability. Dietary diversity varied with household economic capacity, while eating habits and socioeconomic status showed no association, and multiple factors were found to positively influence mothers' willingness to practice peri-urban horticulture.

A profiling study of community gardens in one region of the United Kingdom, which found that gardens differ in how and when they were established, how they are managed and funded, their size, and who uses them and for what purposes. The two most common objectives cited by organizers were community development through food-related activities and contributing to environmental sustainability. On longevity, one third of the community gardens in the study region were found to be no longer active, indicating that survival is not assured. To improve durability, the study suggests gardens need to build a sense of ownership within the local community and be managed in ways consistent with their funding source's conditions and volunteers' expectations.

A thesis examining peri-urban agriculture in Asmara, Eritrea, within an analytical framework of urban population growth encompassing natural population increase, rural-urban migration, and outward movement linked to urban expansion. It draws on primary field data collected with research assistants, secondary data from Ministry of Agriculture and Ministry of Public Works reports, and focus group discussions. Respondents in the context of natural population growth were found to make a viable living from peri-urban agriculture, but also to face considerable challenges. Three sub-groups of farmers were identified; poultry farmers were the most vulnerable, owing to high input costs, uncertainty from avian flu, and an undeveloped distribution network. Vegetable producers had a sophisticated marketing network but low levels of education, large households, and an impending shortage of land and water. The abstract's description of agriculturalists who migrated to Asmara is cut off before stating a conclusion.

A study using qualitative data from 24 urban farming households in Kumba municipality, Cameroon, drawing on key informant interviews with the government agriculture delegate and questionnaires administered to farmers. Urban agriculture was found to have become an important source of fresh produce, employment, and income for those practicing it, but this activity and the livelihoods depending on it were found to be threatened by a number of problems. The study also finds that while urban agriculture contributes to household food supply, its magnitude in terms of utilization, availability, dietary diversity, and financial contribution should not be overemphasized. Suggestions are offered for improving the sector.

To test whether cabbage (Brassica oleracea) leaves -- widely available as market waste in peri-urban agriculture -- could be used in a ground leaching technology (GLT) system to manage root-knot nematodes (Meloidogyne spp.) and improve tomato (Solanum lycopersicum) growth, researchers ran a 2x2x2 factorial experiment combining Bacillus species, Brassica leaf extract, and nematode presence across two seasons under microplot conditions. At harvest, the Bacillus x Brassica x nematode interaction reduced final nematode population density, fresh fruit yield, dry shoot mass, plant height, and stem diameter, while the Bacillus x Brassica interaction increased tomato growth variables; Brassica alone reduced tomato productivity, and overall the extract's efficacy depended on microbial activity, leading the authors to conclude the material was not suitable for use in GLT systems.

This paper examines the outreach program that the C.H. Nash Museum at Chucalissa, located on the grounds of a prehistoric earthwork complex in Memphis, Tennessee, has run toward the surrounding African-American community over the past decade. The archaeological site was first investigated, and the museum was founded, as a byproduct of 1930s Jim Crow-era segregation policies; since its founding, the site and museum have functioned as a place of academic privilege that ignored the surrounding community. Transparency and a commitment to community engagement are described as central to the outreach program, whose highlights include installing an African-American Cultural Heritage exhibit, hosting community events, establishing a community garden, and collaborating with community partners on service projects. Based on a participatory model, the museum has moved to position itself as a social asset and stakeholder in the Southwest Memphis community.

Amid growing interest among community groups in using vacant and underutilized land for urban food production, but with few community-based tools available to assess site suitability or location-allocation decisions, this U.S. study describes a scientific software tool, built in Microsoft Excel, to help community groups identify and inventory the location and condition of vacant and underutilized land, determine relative site suitability, and allocate urban agricultural reuse strategies across the urban landscape. The tool augments the prototype community-based decision support tool (C-SAP) developed by Kirnbauer and Baetz (2011), which already includes a binary scoring methodology for the vacant and underutilized land inventory (VULI) process and an analytic hierarchy process for calculating site suitability indices (SSI). The added capacity, called LOCAL, formulates a multi-objective binary integer program for location-allocation of reuse strategies at the neighborhood, community, or city-wide planning level. The paper summarizes and discusses applying the prototype tool to 21 sites identified as potential future urban agriculture sites.

This doctoral dissertation proposes urban-system strategies for reducing energy consumption and greenhouse gas emissions by introducing eco-innovation into buildings across two economically, socially, and climatically different contexts: Mexico and Spain. For Mexican social housing, it examines an eco-retrofit strategy combining efficient eco-technologies, shading and insulation (roof shading, wall overhangs, window and roof louvers, green roofs), and food production (tomatoes), calculating cooling energy demand and the cumulative energy and CO2 emissions associated with shading materials. For Spain, it examines barriers and opportunities for installing intensive food-producing greenhouses on rooftops of buildings in Mediterranean European cities through multidisciplinary expert seminars, and analyzes potential heat-flow synergy between a building and a rooftop greenhouse focused on winter heating energy demand for a service building in Barcelona. Results indicate that eco-technologies can reduce annual energy consumption in social housing by 31% (35.7 kWh/m2/year), roof-shading strategies save 126 kWh/m2/year, and tomato production in social housing in Mérida, Mexico could contribute a reduction of 662 gCO2eq per kg of tomatoes produced.

This study surveyed 40 trainees of the urban agriculture instructor course at the Gyeonggi Provincial Agricultural Research & Extension Services, South Korea, on October 7, 2011, analyzing the importance and performance of the urban agriculture education program using an IPA (importance-performance analysis) model. Based on the findings, it proposes reforms to the instructor course: teaching should be practice-oriented rather than theoretical so trainees can apply learning in actual urban agriculture, teaching materials should be practical rather than purely theoretical, and since theoretical content is already covered in materials, instruction should emphasize hands-on practice.

A book chapter (2012, no specific region) on Integrated Solid Waste Management (ISWM) based on the 3R approach (reduce, reuse, recycle) discusses optimizing waste management across all waste-generating sectors — municipal, construction and demolition, industrial, urban agriculture, and healthcare facilities — and all stakeholders, including generators, service providers, regulators, government, and communities. It traces solid waste management (SWM) from an original focus on reducing public health risk, to a later environmental focus, to a more recent emphasis on resource conservation and recovery under the 3R approach, and describes the ISWM concept — streamlining source separation, collection and transport, transfer/material recovery, treatment/resource recovery, and final disposal — as expanding under UN Environment Programme promotion from its original municipal solid waste management (MSWM) scope to cover all waste-generating sectors.

A paper framed as addressing a research gap on eco-friendly pesticide use strategies among urban farmers in Lagos State, Nigeria, health impacts, and environmental protection (2012) states that it conducted a structured literature review with thematic synthesis of key findings. However, the abstract's actual content is limited to generic mathematical-formalism language — establishing "bounded error under perturbation," a "convergent estimation process under stated assumptions," a "stable link between the proposed metric and observed outcomes," and an empirical specification described as a linear regression form (Y expressed as a linear function of X plus an error term) — and does not report specific data or results on actual pesticide practices, measured health impacts, or environmental protection outcomes among Lagos urban farmers. It closes by calling on stakeholders to prioritize inclusive, locally grounded strategies and improve data transparency.

This study examines the motivations behind women's involvement in urban agriculture in small agro-towns of Kwara State, Nigeria. A total of 1,801 women farmers were selected from 13 settlements across 8 local government areas, and data were analyzed using simple percentages, graphic illustrations, charts, cross-tabulation, and stepwise multiple regression. The study identifies three factors — food security, income supplement, and accessibility to land — as the best predictors of women's involvement, together accounting for 98.6% of the explained variation. It recommends official recognition of urban agriculture and provision of financial resources to help women expand their farm plots.

This paper presents an English case of urban agriculture, the Edible Public Space Project in Leeds, situated within urban agriculture initiatives committed to socio-environmental justice, the reproduction of common goods, and urban planning that promotes the right to food and bottom-up construction of urban space. The case study is framed as action-research at the intersection of urban planning policy, community work, and critical geography. Unlike many similar initiatives, the project is presented not as a merely temporary activity tucked into the city's spare folds, but as an experiment that imagines and implements alternatives to current forms of urban planning, contextualized in light of the ecological, financial, and social crisis of the preceding decade.

This piece by André Viljoen and Katrin Bohn of Bohn&Viljoen Architects juxtaposes the organopónicos, or market gardens, of Cuba — which proliferated after the US trade blockade of the 1990s and the resulting fuel shortages — with more recent food-production experiments in North American cities that draw on the Cuban example. The authors argue that in urban agriculture there is a direct connection between scarcity and abundance, with the threat of food shortages repeatedly acting as an effective trigger for food-growing enterprises, and that produce can be grown even with few or limited resources.

This study examines the impact of school garden programmes on nutrition knowledge and food security among primary school students in rural Mozambique. While such programmes have been implemented across various regions with mixed results, this study used a mixed-methods approach combining qualitative interviews and quantitative surveys with primary school students and their parents or guardians. Students showed a statistically significant improvement (p<0.05) in nutrition knowledge, with an average score increase of 20% on the post-intervention survey compared with pre-test results. The findings indicate that the school garden programmes positively influenced students' nutritional knowledge and contributed to their families' food security in Mozambique's rural areas. The authors state that further studies should examine long-term impacts and potential barriers to implementation.

This study treats Brianza, Italy, as a prototype of recurring relationships between residential and agricultural spaces in contemporary towns and cities, using their differences to trace the evolution of the historical landscape, the causes of its deterioration, and new planning possibilities. The simplified rural fabric of the Vimercate countryside, the strings of woodland and built-up areas in the hills, urban clearings, and the woodland and countryside of Groane are each said to open prospects for new, locally specific types of urban agriculture. The proposed future is plural, examining different relationships among agriculture, collective spaces and redevelopment of existing settlements, while opting for a halt to urban growth and reconstruction of infrastructure and landscape quality in the Brianza area.

A theoretical discussion grounded in structural-functionalist sociology (Fend, 1980; Parsons, 1959) addresses the two functions schools and universities serve for society and the individual: qualification and integration-enculturation. It engages the proposition that people learn for life rather than for school, but the abstract text itself contains no specific description of school gardens or technology-based learning environments.

A mixed-convergent parallel design intervention study tested whether participation in a community garden could improve diabetes control among members of a Midwest United States community of Marshallese immigrants. Marshallese clients recruited from a local community health center took part in a community garden, and qualitative data from field observations on cultural norms and beliefs, food perceptions and barriers to health care corroborated data gathered at diabetes follow-up medical appointments. Persons who actively participated in the community garden showed a significant reduction in HgA1c after the intervention compared with those who did not participate, though the abstract does not report the number of participants or the size of the reduction.

Based on Agricultural Location Theory, 23 matched soil-wheat sample sets were collected from Beijing's central city, suburban plain and exurban plain zones to analyze the accumulation, chemical forms and bioavailability of lead under differing intensities of human activity. Urban soil showed lead contamination with an average concentration of 35.59 mg/kg above the limit, likely from traffic and industrial emissions, and suburban agricultural soil also showed localized lead contamination from long-term sewage irrigation, with lead more mobile in urban agricultural soil than in suburban soil and least mobile in exurban agricultural soil. The average bioconcentration factor of lead in wheat seeds was a low 0.0044, but some lead concentrations in wheat seeds grown in urban and suburban agricultural soil exceeded the standard limit, indicating a potential health risk to residents in those areas.
