This study investigated the thermal environment and visitor behavior at a large rooftop garden on a commercial building during summer. Findings indicated that resting places in tree shade were "non-Hot" under high solar radiation, though SET* was higher than in shaded open spaces due to wind speeds around 1m/s. The rooftop garden featured well-shaded footpaths that provided "non-Hot" conditions for most of the afternoon. Tree shade was desirable on fine days, while open spaces were preferred on cloudy days. SET* was identified as the most appropriate index for evaluating the relationship between human behaviors and the thermal environment.

The effectiveness of low-cost irrigation methods (drip irrigation kits, furrow irrigation, and watering cans) in reducing contamination of lettuce irrigated with untreated wastewater in urban farming in Ghana was assessed. Analysis of 396 lettuce, 72 soil, 15 poultry manure, and 32 water samples revealed that lettuce irrigated with drip irrigation kits had the lowest contamination levels, with an average of 4 log units per 100g fewer thermotolerant coliforms than those irrigated with watering cans. However, drip kits often clogged, required lower crop densities, and restricted other routine farm activities.

In South Africa, traditional leafy vegetables have been labeled as weeds since the 1960s, leading to a negative perception and unwillingness to use them. Awareness activities in six communities, including training sessions in seven schools and eight community gardens, aimed to improve the status of these crops. These activities resulted in increased awareness of their poor conservation status, appointment of seed keepers, and a noticeable increase in demand for seeds and production training.

A cross-sectional survey of 296 households in Kampala, Uganda, examined the impact of sociodemographic and farming variables on household food security and nutritional security of children aged 2-5 years. Household food security score was significantly positively correlated with the number of tropical livestock units, dietary diversity, percentage of energy from animal-source foods, and weight-for-age z-score. Consumption of animal-source food was negatively associated with C-reactive protein level, which was negatively associated with hemoglobin level, and hemoglobin was positively associated with weight-for-age z-score.

A study (Applied Environmental Education & Communication, 2007) summarizing a 2000 investigation of school garden program variation and its impact on 427 third-grade students, developed a typology of nine garden types from a survey of 28 third-grade teachers, classified by activity intensity (high, medium, low) and garden form (flower, vegetable, or combination). Analysis of covariance found significant differences among garden types in students' attitudes toward science and toward the usefulness of science study. No significant differences were found among garden types in students' sense of responsibility or environmental attitudes; scores on those measures were uniformly high with little variation regardless of garden type.

This introductory study in Arroyo Naranjo municipality, Cuba, examined the use of Luyanó effluent wastewater for irrigation in urban agriculture. The wastewater was classified as low contamination based on BOD5 and COD values and posed no toxic contamination risk to soil or environment. However, it should not be used without prior treatment for direct consumption crops due to its microbial load. Experimental plots with carrot, radish, and marigold showed high agricultural yields, and radish harvests had no bacterial contamination.

In Sub-Saharan Africa, faecal sludge management practices are often financially unviable due to widespread lack of municipal involvement, paucity of legal provisions, and absence of stakeholder coordination. This leads to indiscriminate dumping of faecal sludge in urban areas or its untreated use in urban agriculture. These practices pose permanent and serious health risks and contaminate scarce ground and surface water. This research aims to develop an innovative strategic planning approach for sustainable urban faecal sludge management to minimize public health and environmental risks.

A 2005 study in Campinas, Brazil, analyzed the city's Community Garden Program (PHC) to support the formulation of new urban and peri-urban agriculture policies. Analysis of PHC management revealed an almost total disengagement between the program and sectoral policies such as education, health, and social action. However, individual actions were found to be important for project implementation and success, and the projects were significant in the lives of beneficiaries.

This study investigated the effectiveness of methods used by nutrition educators to promote the Women, Infants and Children (WIC) community garden project in Albuquerque, New Mexico, USA. A survey of 257 clients from five clinics found that less than 30% of clients had been exposed to the project, and caseload was unrelated to the promotion methods used. However, clients exposed to any method of promotion were more likely to garden than those not exposed, and importantly, clients reported eating more vegetables after being exposed to the project.
