This research investigated the impact of a school garden environmental education program on 10 pupils diagnosed with mild to moderate intellectual disability in two Special Education Primary Schools in Greece. Using semi-structured interviews and descriptive statistical analysis to compare two groups of pupils, the study found that students who participated in the program were more familiar with environmental concepts and possessed skills directly linked to Environmental Education than their non-participating peers. Additionally, participating pupils perceived outdoor activities as part of the formal learning process, unlike their peers.

This paper studied seven community gardens with varying organizational designs, objectives, and gardener motivations to investigate their influence on social cohesion. It found that in all cases, people interacted, got to know each other, and mutual help was widespread, concluding that community gardens contribute to social cohesion regardless of participants' primary motivations. Social aspects also provided added value for those primarily motivated by growing vegetables.

An extensive survey of urban rodents in Niamey, Niger, investigated the presence and distribution of rodent-borne pathogenic Leptospira species. Leptospires were not detected in the core city, but L. kirschneri was found in Arvicanthis niloticus and Cricetomys gambianus, rodent species restricted to irrigated cultures within the city. This study indicates the importance of market gardening in the maintenance and circulation of leptospirosis within Sahelian cities.

This study assessed heavy metal concentrations in 12 groundwater samples from Keko and Kigogo areas in Dar es Salaam, Tanzania, during dry and rainy seasons. While copper and zinc concentrations were low, lead concentrations were detected beyond WHO permissible levels (0.01-0.35mg/l). This high lead presence may be attributed to urban agriculture activities, onsite facilities, and industrial waste discharge around the Msimbazi river.

Over half of humanity resides in cities, and most cities cannot produce enough food to sustain their residents. Some cities are exploring urban agriculture to create more resilient food systems, aiming for food security despite external forces. However, some argue that the global food system is too interconnected with local systems, making no system entirely invulnerable. This chapter focuses on three case studies exploring interlocking food deserts to illustrate how global and local processes converge on health issues like obesity in urban settings.

Urban agriculture is gaining popularity, often for its contribution to urban greening, re-establishing connections between urban dwellers and agricultural and food production, and among urban dwellers themselves. However, urban agriculture also involves significant health issues, which advocate for urban planning that promotes its maintenance or establishment under healthy environmental conditions.

This study investigated the processes leading to sustained or eroding community engagement over time in urban community gardens within a low-income urban neighborhood. Key informant interviews were conducted with gardeners from various community gardens, and the data was used to understand the context of garden establishment and to revise a system dynamics model based on collective action theories. The model, which incorporated eight main structures including gardeners, land, activities, and social relationships, successfully produced both sustained and eroding community engagement.

A study on vegetable production in Ghana's Tano South District surveyed 132 urban farmers and 5 stakeholders. Farmers relied solely on chemical pesticides for pest control and lacked in-depth knowledge of Integrated Pest Management (IPM). Inappropriate handling and non-use of protective clothing led farmers to report health issues like dizziness, skin irritation, and nausea, while indiscriminate spraying resulted in pesticide residues posing serious health risks to consumers and the environment.

The documentary film "Plant This Movie" (2014, 83 min) explores our relationship with food and the wasted space and resource of the 21st-century lawn. This film, one of many similar documentaries on urban farming, proposes learning from and improving upon past mistakes of the Green Movement. It notes that many agricultural nonprofits, including one highlighted, fail due to lack of funding, and while it suggests sustainability efforts should be run like a business, only a fraction of the film is dedicated to this aspect.

This text explores the concept of "material participation," where everyday material practices like gardening, washing, and cycling are proposed to facilitate engagement in social and public life. It suggests that material environments, such as kitchens and allotment gardens, have unique capacities to involve people and make broader social problems accessible for intervention. The text raises questions about the legitimacy, efficacy, and distinctiveness of these explicitly material forms of engagement.

This chapter focuses on urban food supplies and the challenges of managing waste flows from urban households and markets in developing countries. Large amounts of municipal solid waste, human excreta, and wastewater are produced, most of which end up in non-engineered landfills or pollute the urban environment. It is noted that these wastes pollute the urban environment, especially in low-income countries with less developed sanitation infrastructure.
