This chapter explores the role of agroecology in smart cities and investigates how Information and Communications Technologies (ICT) could spread agroecological approaches to boost urban agriculture. Smart cities are criticized for their inability to build just and inclusive environments, and ICT alone cannot guarantee sustainable development. While agroecology enhances ecosystem services and human well-being, its introduction in urban ecosystems is complex. The chapter suggests ICT could provide tools to enhance dwellers' competencies in practicing agroecology, ultimately exploring how smart urban agriculture contributes to food sovereignty and ecosystem service maintenance.

This study extensively reviewed the literature on how urban agriculture (UA) can contribute to flooding risk management for building water-resilient cities. UA plays a key role in transforming linear water economies into circular ones, thereby reducing urban areas' dependence on rural areas for ecosystem services, including flood risk management. UA exhibits higher infiltration capacity, and urban flood-prone areas can be allocated to UA for flood management. The Sponge City Concept demonstrated the possibility of reducing 100-year storms to 25-year storms.

This systematic review evaluated how different modes of governance support ecosystem services (ES) in small-scale urban green infrastructure (UGI). Governance was assessed in six types of UGI: small parks, community gardens, vacant lands, rain gardens, green roofs, and street trees, examining the characteristics of four governance approaches: adaptive, network, mosaic, and transformative. Each governance mode was found to be potentially effective for managing the ES of certain small-scale UGI. The study highlights knowledge gaps at the intersection between governance arrangements and ES in small-scale UGI.

A case study was conducted at The Old School Community Garden (TOSCG) in the Adelaide Hills, Australia, teaching gardening to primary students. This project focused on using the garden as a learning place for Year 1 students (aged 6–7) working with Year 4 students (aged 9–10). Gardening provides young people with opportunities to learn science concepts while addressing local issues like organic food production, encompassing central aspects of science learning such as soil science, biological science, ecosystem management, and sustainable food supply.

Monika Egerer, Brenda B. Lin · CABI Reviews · Global

This review evaluated ecosystem services (ES) within urban agriculture (UA) systems and the trade-offs between these services. Urban agriculture provides many benefits and environmental services such as food provision, social cohesion, and climate regulation. However, it was shown that management decisions can create trade-offs between ecosystem services, where an increase in one service may potentially reduce the system's ability to provide another service at a desired level.

Tong Zou, Ali Cheshmehzangi, Ayotunde Dawodu, Eugenio Mangi · Journal of Resilient Economies (ISSN 2653-1917) · Global

This study investigated how urban agriculture can improve the sustainability and resilience of the urban food system through the analysis of existing literature. The literature review, conducted on April 11, 2022, on the Web of Science database, included bibliographic coupling, co-citation analysis, and co-occurrence analysis. Findings highlighted that urban agriculture alone cannot substitute large-scale food systems in the short term, but it could be a promising approach in the future.

Urban agriculture, which involves growing food in cities, promotes local and sustainable food systems to address global challenges such as growing urban populations, climate change, and natural resource scarcity. Farming in cities positively impacts the environment, ecosystem, and climate, while also bringing communities together and improving citizens' health.

Davide Marino, Giampiero Mazzocchi, Davide Pellegrino, Veridiana Barucci · Land · Italy

This study investigated the role of Ecosystem Services (ES) assessment within a "place-based policy-mix model" for urban planning, testing and integrating three ES assessment methodologies: mapping and assessment, expert-based evaluation, and social perception. Results indicate that mapping assessment assigns higher values to regulating ecosystem services, expert-based evaluation assigns slightly lower values to regulating ecosystem services, and social perception highlights the importance of cultural ES but tends to underestimate other ecosystem functions. These methodologies lead to sectoral, non-dialoguing policies based on partial and non-integrated information.

This study investigated the drivers of de-agrarianization in post-socialist cities, using Brno, Czech Republic, as a case study through qualitative interviews. It found procedural issues in preserving architectural heritage during the redevelopment of a former Cistercian monastery site, often resulting in only fragments being preserved. The research also demonstrated a decline in the use of urban agricultural properties, which are rapidly transformed into new urban environments under intense urbanization pressures.

Demet Ülkü Gülpınar Sekban, Duygu Akyol · Journal of Urban Planning and Development · Turkey (Trabzon)

This study examined the contribution of residential gardens to ecosystem services in Trabzon City, Turkey. It was determined that both spatial needs and ecosystem benefits can be met with the same Green Infrastructure (GI) elements, and landscape value is supported by GI elements such as edible gardens, pollinator gardens, rain gardens, biological ponds, and green roofs. GI elements combining vegetation and water landscape elements have a higher potential for ecosystem services. The study concluded that green areas of residential gardens should be planned and designed through a holistic GI-oriented approach based on the total building parcel.

This study investigated the needs and commercialization challenges of chinampa producers in Xochimilco, Mexico City, to assess the potential of a green label. The analysis, based on a literature review and producers' mental model analysis, found that unresolved issues like commercialization problems, consumers' unwillingness to pay fair prices, soil degradation, and poor irrigation water quality persist. These issues make it difficult for most producers to bear certification costs, indicating that implementing a green label would likely fail to deliver its intended benefits.
