This is a record of the open discussions from a four-session workshop held in Netanya in June 1996. The first session addressed forming growers' associations to secure access to land and to consumers; the second covered technology transfer for water management; the third examined ecological aspects of urban and peri-urban gardening; and the fourth compiled mission statements each participant wrote after the presentations and discussions. The main synergy expected from urban and peri-urban farming was identified as its use of urban waste products to yield fresh agricultural produce, with geographers and cartographers seen as playing an important role in supporting peri-urban and urban farmers.

"Sharing economy" has become a popular umbrella term for a variety of consumer activities involving the sharing of goods and services, covering transactions across almost all business areas including accommodation (e.g., Airbnb), food (e.g., community gardens), and transport (e.g., Uber, BlaBlaCar). This chapter focuses on sharing-economy research from a consumer perspective, summarizing current findings and identifying research gaps. It examines factors that foster or hinder consumer involvement in the sharing economy, such as demographic aspects (age, digital literacy) and motivational aspects (environmental friendliness, monetary considerations), and looks at the relationship between consumers and other actors (providers and other consumers), such as trust, while discussing the use of social-science methods and practical implications for future research.

Published by JTC on 27 Feb 2019, this article describes urban farming company Comcrop, whose founder Allan Lim started his first community farm in Bukit Panjang in 2011, later ran a rooftop farm at *SCAPE, and then built a 36,000-square-foot facility with six greenhouses at a JTC site in Woodlands. The Woodlands farm grows leafy vegetables such as pak choy, lettuce and mizuna at high output; CEO Peter Barber states the first greenhouse alone can produce 40 to 50kg a day. Barber envisions placing farms in every neighbourhood in Singapore to employ locals and supply supermarkets, while Lim stresses the need to build agricultural research capability in Singapore.

Vegetable production on green roofs faces multiple challenges, resulting in minimal current activity despite its potential for urban agricultural sustainability. While intensive green roof systems are considered suitable for vegetable production, extensive systems with shallow-rooted crops like lettuce, kale, and radish show the greatest potential for sustained productivity due to building weight restrictions. Deeper-root crops like tomatoes require constant monitoring of fertility and moisture. Green roofs are not presented as a total solution for urban food provision.

This study developed a quantitative framework to assess global aggregate ecosystem services from urban agriculture (UA) using global datasets in Google Earth Engine. Existing urban vegetation provides an estimated $33 billion annually in ecosystem services. An intensive UA adoption scenario projects potential annual food production of 100–180 million tonnes, energy savings of 14–15 billion kilowatt hours, nitrogen sequestration of 100,000–170,000 tonnes, and avoided storm water runoff of 45–57 billion cubic meters. Under this intensive scenario, the value of ecosystem services could reach $80–160 billion annually, with significant country-to-country variability.

This review maps the use of food sovereignty principles in urban and peri-urban agriculture (UPA) in Zimbabwe, addressing its potential for food security. Despite UPA being ingrained in urban households' livelihoods, institutional arrangements governing the practice remain ambivalent. The review underscores that the failure to involve all stakeholders undermines UPA, leading to heightened food insecurity and unsustainable practices.

This study evaluated small-scale urban agriculture systems in Australia using economic and emergy (embodied energy) analyses. While these systems used land efficiently, they were relatively inefficient in their use of material and labor resources. Benefit-to-cost ratios demonstrated that, on average, the gardens ran at a financial loss, and emergy transformity was one to three orders of magnitude greater than many conventional rural farms. Only 14.66% of all inputs were considered "renewable," resulting in a moderate mean environmental loading ratio (ELR) of 5.82.

This project explored new ways for designers to model human behavior by using social practices, an approach relatively unexplored in design. It extended social practice models into service design to create tools and approaches that support the development of social practices. Community Supported Agriculture (CSA), a system where community members buy shares from local farmers for weekly produce, was used as a case study to test these new approaches.

The Urban Foodprints (UF) methodology was applied to assess the environmental sustainability of high-yield urban agriculture in Riyadh, Saudi Arabia, focusing on tomatoes. While urban production in high-yield greenhouses could reduce Global Warming Potential by 9% and water savings were significant, the energy needs of these greenhouses were considerably higher than the baseline. This indicates a trade-off where environmental benefits are partially offset by increased energy consumption.

A systematic review of literature from 1975 to 2018 on urban agriculture yield research found that only 5 out of 25 articles actively collected water use data from the perspective of water use efficiency, all from purpose-built experimental gardens. Given the scarcity of literature on urban agriculture water use efficiency and measurement, a case study from South Australia demonstrated the diversity of water pricing, sources, and irrigation methods. Four equations for calculating urban agriculture water use efficiency (WUE) were proposed.

This project aimed to explore the smart integration of food production in cold urban environments and to sketch an intelligent platform to guide a comprehensive, city-wide approach to urban farming in winter cities. The challenge involved integrating large databases related to energy consumption, building performance and size, and solar radiation, to visualize data in an easily understandable manner for city stakeholders.

Ayinde BA, Nicola Cantoreggi · International Journal of Environment Agriculture and Biotechnology · Senegal (Dakar)

This study focused on the commercial dimension of urban and peri-urban agriculture (UPA) in the Dakar region, Senegal, involving 214 market gardeners across three production areas. Results showed that UPA, specifically urban market gardening, constitutes a full-fledged commercial activity with monetary income significantly higher than Senegal's minimum wage. This almost exclusively commercial orientation allows agri-urban households to cover their food and non-food expenses inherent in urban living.

A study on "The New Hope" farm in Camagüey, Cuba, evaluated human urine as a fertilizer for corn cultivation under family farming conditions. Family-collected human urine, stored for six months and applied in dilution, was compared to a mineral fertilizer and an unfertilized control using a randomized block design with 18 sample plants per treatment. Results showed that human urine yielded equivalent results to mineral fertilization, with no significant differences, but both differed from the unfertilized treatment, concluding that urine is an economic alternative for family farming.

This systematic literature review aims to clarify the concept of Alternative Food Networks (AFNs) by conducting a thematic analysis of academic definitions. The literature indicates a lack of clarity regarding AFNs, which are often defined by what they are not, rather than what they are. The study seeks to address this knowledge gap and contribute to theory and empirical development.
