This chapter examines the diverse uses of urban green spaces, encompassing recreation, biodiversity conservation, public health, and regulatory ecosystem services, with food production also re-emerging. Changing urban populations, including cultural diversity and ageing, have altered demands and uses. The study identifies a critical need to manage potential conflicts and trade-offs among these varied demands, despite many uses being able to coexist.

Ensuring equal access to attractive green spaces for all urban residents, including vulnerable groups, is crucial due to pandemics, climate change, and lifestyle diseases. Both formal and informal green spaces provide ecosystem services, and smaller green infrastructure can be effective in compact city centers.

This study examined how family farming fosters climate-resilient food systems through a systematic literature review of 37 documents over 22 years. It concluded that family farming facilitates easy access to food and nutrition by utilizing family-sourced land, labor, and capital, and by securing access to technology and markets. Farming families employ diverse strategies, such as crop diversification, adjusting planting times, and cultivating high-value crops and fish, to strengthen their food systems.

This study investigated the effect of five nitrogen levels (80-160 ppm) and two pot volumes (6 L, 8 L) on lettuce (cv. Robinson F1 hybrid) in Giza, Egypt, during autumn 2022 and 2023. Increasing substrate volume from 6 L to 8 L and nitrogen concentration from 80 ppm to 140 ppm increased vegetative growth and yield. The 8 L volume and 140 ppm nitrogen concentration yielded the highest results for vegetative growth, yield, and nutrient content. However, 6 L pot volume with 80 ppm nitrogen achieved the highest net profit despite lower fresh weight, by providing the lowest nitrogen use efficiency and natural resource consumption.

This review emphasizes the multiple environmental, economic, energy, and social benefits of green roofs installed on urban buildings. Green roofs are reported to remove atmospheric pollutants, release oxygen, mitigate the urban heat island effect, reduce building energy consumption, improve rainwater management, and promote urban agriculture. Their construction is financially subsidized in several countries due to these benefits, which contribute to urban sustainability and resident well-being.

This study, based on a year-long facilitation of a school terrace-garden in a metropolitan city, outlined how situated and embodied interactions can foster an understanding of diverse ecological practices. It indicated that multi-modal sensorimotor experiences and the possibility of sharing these with others motivate children to expand their sphere of environmental activities beyond the site of learning. Students extended their care-based interactions with the garden to their communities and broader ecological issues.

Algerian cities face uncontrolled urbanization, with Algiers experiencing a reduction in agricultural area per inhabitant from 0.82 hectares in 1962 to 0.18 hectares in 2010. This study, using historical analyses, interviews, and field observations, assessed the integration of urban and peri-urban agriculture (UPA) in Delly Ibrahim to restore ecological and economic balance and enhance local food security. Findings indicate that UPA can play a crucial role in mitigating negative urbanization effects by preserving agricultural land, ensuring secure local food supplies, and promoting environmentally friendly development.

This study investigated the effect of urban environmentally relevant concentrations of zinc in soils on nutrient exchange between arbuscular mycorrhizal fungi and pea plants using radio-isotope tracing. It found that at higher zinc concentrations, the transfer of phosphorus from fungi to plants and carbon from plants to fungi dramatically decreased. The results suggest that while urban horticulture has potential for food production, the unchecked presence of contaminants like zinc in urban soils may critically hinder its realization.

This paper investigates the production, economics, and sustainability of vermicompost, an organic fertilizer made by vermicomposting organic waste with earthworms. Vermicomposting is presented as a sustainable waste management and organic agriculture option that can be economically profitable, depending on consumer awareness, distribution, and production scale. It contributes to sustainability by reducing landfill waste and promoting soil health.

This paper examines the historical evolution and current state of Lisbon's foodscape. Historically, Lisbon possessed large agricultural spaces and a tight-knit food network, but nowadays, food has largely disappeared from the public realm. Mapping past and present urban food assets is key to providing a comprehensive portrait of Lisbon's foodscape and its potential for solutions.

This article discusses the technical feasibility and design strategies for integrating high-rise residential buildings with urban agriculture in Hong Kong, using the “Green Tower Hong Kong” architectural design competition as a case study. A resilient residential high-rise building integrated with shared gardens and greenhouses was proposed for the Kwun Tong Center site. The final design can provide apartments for 2500 individuals, produce 340,750 kg of vegetables with 156% self-sufficiency, and generate 1,080,000 kWh of electricity annually.

This chapter describes the practice, processes, and ethical tensions of using cell phones for visual data collection, representation, and analysis in school/community garden research projects. The findings suggest that while gardens and cell phones have the potential for enhancing experiential learning, increased well-being, and ecological awareness, their use needs to be highly contextualized within critical discussions related to settler colonialism, consumerism, neoliberalism, and (green) gentrification.

This study investigated the effects of urbanization on urban vegetable farmers' adaptation in the Greater Accra Metropolitan Area (GAMA), Ghana, using an exploratory sequential mixed method. Qualitative data involved 29 farmers from 10 farm sites, and quantitative data involved 251 farmers from 16 farm sites. Changes perceived by farmers included climate, land scarcity, increased population, and lifestyle dynamics, with population increase negatively resulting in polluted streams and farmer evictions due to land scarcity. Farmers adapted by using multiple water sources, intensification, and relocating to cheap lands.

This research extended the land sharing and sparing framework to urban land use, quantifying the impact of urban services, food production, and ecosystem services. The results showed that land-sparing scenarios had a 23.6% lower overall value loss than sharing scenarios on average. However, while land-sparing mitigates losses in food production and ecosystem services, it increases the cost of urban services, creating a trade-off that challenges achieving an optimal win-win situation.

This review examines soil-based urban agriculture and high-tech plant factories for urban food resilience. It finds that while vertical farms produce high yields, inhabitant involvement is minimal, offering no social advantages. Automated plant factories require few highly qualified personnel and are unlikely to contribute to urban social well-being in the future.

This paper argues for a re-evaluation of current trends in assessing global health and environmental sustainability through the prevalence of diseases and natural resource availability. It suggests that achieving present needs without compromising future generations requires evolutionary and swift transformation in health for all programs, eco-friendly production and consumption, and urban farming. Global health and environmental sustainability should be summarized as the study and application of attaining welfare equity for all people in a sustainable environment.

This mini-review discusses the extensive use of AB mix nutrients in Malaysian urban farming, noting their role in high yields but also their contribution to significant environmental pollution when overused. Although a survey of local entrepreneurs showed most complied with guidelines for chili plants, intensive use of fertilizers leads to nutrient leaching into the soil, causing environmental pollution and affecting humans, livestock, and microbial life. The review emphasizes the need for controlled nutrient application to prevent soil degradation and groundwater contamination.
