This literature review explored the subjective aspects of Community Supported Agriculture (CSA) participation. The methodology involved selecting papers with specific word combinations and further studying references and recommended articles. The review found that CSA participation can be interpreted not only through factual advantages but also through aspects like Similar Thinking, Locality (urban-rural axis), Personal Care, Lifestyle Change, and Rewriting of Schemes, which are considered equally important.

This study investigated toxic metal and PAH contamination in rooftop soils and vegetables (red amaranth, spinach) in urban and peri-urban Bangladesh. Urban rooftop soil and vegetables were highly contaminated with toxic metals and PAHs compared to peri-urban samples. Lead (Pb) and cadmium (Cd) concentrations in urban vegetables exceeded safe limits. However, health risk indices indicated that the levels of toxic metals and PAHs in urban rooftop vegetables would not pose carcinogenic or non-carcinogenic health risks for adults and children, deeming them safe for consumption.

A study conducted in the Kasungami district of Lubumbashi, Democratic Republic of Congo, investigated the link between the use of polluted waters in urban agriculture and heavy metal contamination in soil and cultivated vegetables (amaranths, broccolis). Physicochemical and mineral analyses of water, soil, and plant samples revealed that heavy metals, except cobalt, were present in the water used for urban agriculture at concentrations below quality standards, but the soil contained heavy metals at phytotoxic concentrations. Only broccolis were contaminated with lead, while amaranths had heavy metals below quality standards. These findings suggest that urban agriculture in large agglomerations of the DRC could endanger consumers' health.

This study was the first to examine user satisfaction and views on open and green spaces in Güzelyurt (Morphou), Cyprus. A questionnaire was conducted with 60 participants to understand their suggestions about existing open and green spaces. According to the findings, respondents were mostly dissatisfied with urban and open spaces in the city. The study indicates that local authorities or municipal organizations should legalize the planning of urban parks, open spaces, and green areas with a long-term perspective.

A one-year cluster randomized controlled trial in Nepal (2018-2019) with 779 schoolchildren (8-12) and their caregivers across 30 schools tested the impact of combining school and home gardens on food choices. The intervention increased caregivers' food and nutrition knowledge by 26%, agricultural knowledge by 5%, liking for vegetables by 10%, and home garden productivity by 15%. For children, it had no effect on food and nutrition knowledge but increased their liking for vegetables by 6%, healthy food practices, and vegetable consumption by 15-26% across different periods.

A study of approximately 300 leisure gardeners in Zurich, Switzerland, investigated how self-reported psychological restoration related to garden type, the number of plant species, and garden-related stress. Allotment gardeners reported higher restoration levels compared to domestic gardeners. Restoration was positively related to the number of plant species via the perceived restorativeness of the garden, but garden-related stress or negative affect was negatively related to the restoration outcome.

This study evaluated gardening motivations using a 14-item scale and questionnaires in three Swiss cities (N=409) and one Chilean city (N=167). While individual scale items showed significant differences between Swiss and Chilean responses, a principal component analysis revealed nearly identical component structures for both samples. Restoration was the strongest motivational component, followed by socialization and food production, suggesting motivations are not context-dependent.

This literature review examines urban agriculture (UA) models, their implementation contexts, production needs, and impacts. It highlights that UA faces limitations, particularly restricted access to good quality (unpolluted) soil, water, and air, which can negatively impact productivity. UA can also have negative impacts on ecosystems and human health, such as pollution and diseases, depending on management methods.

Microgreen farming is presented as a popular method for income generation in urban agriculture. It is characterized by high nutrient density, a fast turnaround time (10-14 days after germination), year-round cultivation, minimal resource requirements (seeds, soil, water, trays), and a high yield-to-space ratio. Prices for microgreens range from INR 150-250 per 50 grams, indicating good market value for urban farmers.

This systematic scoping review analyzed 46 manuscripts from 30 studies published between 1990 and 2019 to understand clinical strategies used by healthcare organizations to increase patient access to fruits and vegetables (F&V). Six program models were identified, including garden-based programs and CSA. The overall quality of the included studies was weak due to selection bias and incomplete reporting, with only 6 out of 30 studies including a control group. While some studies showed improvements in dietary intake, objective health markers such as blood pressure and BMI had mixed results.

The Nutrition Center of the Philippines (NCP) collaborated with the Department of Education to develop nutrition education modules for elementary schoolchildren, integrating classroom, garden, and home activities. A survey in two towns found that pre-school children in households with home gardens ate vegetables more frequently and had higher dietary diversity scores than those without. NCP also promoted nutritional values through TV ads featuring student-written poems, which received an award in 1985.

An analysis of 63 Korean and 90 overseas articles on urban gardens compared the types of physical and social benefits provided by gardens in urban areas. Community gardens were the most significant type in both Korea and overseas. Due to narrow urban structures, Korea focused on using rooftop, wall, and alley spaces, while overseas focused on promoting health and reducing food inequality through larger allotment and kitchen gardens. Urban gardens were found to have a positive effect on urban biodiversity, providing comprehensive environmental (37.73%) and social (62.27%) benefits.

This study analyzed water and soil samples from three market garden sites in Yaounde, Cameroon, from October to December 2016, for physicochemical characteristics and parasite identification. The analysis of 82 samples revealed the presence of 3 protozoans (Entamoeba histolytica, Sarcocystis sp., and Giardia intestinalis) and 11 helminths in the soil. The presence of viable helminths suggests that harmful soil pathogens such as protozoans and helminths can spread through market gardening.
