The Dominican Republic's public investment in education was 2% of GNP in 2010, falling below UNESCO's 6% minimum. This pilot project, conducted at The Community for Learning School (TCFL) in the Dominican Republic during the 2011-2012 school year, enhanced 5th-8th grade science curricula with four activities: composting, a school garden, a garbage project, and an energy audit. While the school garden and composting project improved student motivation for group work and left a positive perception of environmentally friendly practices, knowledge gain about their environmental benefits was not as expected.

The 2011 film "A Community of Gardeners" explores the impact of community garden projects in various urban settings. It highlights that community gardens fulfill important needs for individuals and communities by providing access to fresh food, increasing self-sufficiency, improving urban aesthetics, and strengthening communities through connections across diverse socio-economic groups. The film also presents the historical origins and different incarnations of community gardens.

Carolin Mees, Edie Stone · · United States (New York City)

In New York City, community gardens were established by resident groups in the 1970s, contributing to recreation, food security, and sustainable urban development. Their number has fluctuated over the past 30 years, with approximately 600 gardens existing today, over 300 of which are on public land. Recently, in response to climate change and economic crisis, elements like beehives and rainwater harvesting have been legalized and used to maximize food production and conserve water. This chapter will use qualitative data analysis, secondary literature discussion, and participant observation to evaluate the employment and function of these garden components and how the city's community gardens contribute to a sustainable city.

Cai Jianming, Guo Hua, Larissa Muller, Margaret Zhou · Journal of Resources and Ecology · China (Beijing)

This study analyzed changes in Beijing's food footprint and food self-sufficiency rate over a 30-year period from 1981 to 2011. During this time, the food footprint grew from 11,800 to 29,400 km2, while the self-sufficiency rate for vegetables dropped from 59.3% to 39.0%, with significant declines also seen for fruit, grain, and edible oil. It was concluded that with proper shifts in farmland use, full utilization of temporary idle land, and the development of rooftop farming, Beijing could increase its vegetable self-sufficiency rate to 60% without significantly reducing the production of other types of local food.

Fernando Menendez Cobelo · · Venezuela (Caracas)

This project focuses on Caracas, Venezuela, against the backdrop of global economic transformations and population growth redefining urban boundaries and forms. Caracas faces housing issues and urban spatial imbalances due to rapid urbanization and population influx from past oil industries. The presence of large underutilized spaces, such as the 103-hectare former military airport site "La Cariota" in the city center, is noted as hindering urban improvement.

Jan-Eelco Jansma, W. Sukkel, E.S.C. Stilma, Alex C. van Oost, A.J. de Visser · · Netherlands (Almere)

This case study in the Dutch city of Almere calculated that 6,200 hectares of conventional farming land (or 8,100 hectares for organic production) are needed to produce approximately 20% of the daily food basket for 350,000 future citizens. Local production reduces greenhouse gas emissions by an estimated 27,000 tonnes/year, a relatively small reduction as most products are already produced in the Netherlands. The study emphasizes that other aspects, such as food basket composition, local food distribution system redesign, consumer behavior, and fossil energy use reduction, must be considered for reducing food miles, fossil energy use, and greenhouse gas emissions.

Micro-agriculture refers to small-scale agriculture, in contrast to intensive agriculture and monoculture. It is a collection of 'small scale' agricultural practices, including horticulture (such as urban vegetable gardens), fruit-growing, or flower-growing. Micro-agriculture is a landscape defined by garden plots and materials, forming a unified yet diversified whole that differs from traditional agricultural landscapes in its reduced scale, biological richness, material variety, and heterogeneous landscape.

This paper, focusing on Toronto, identifies subtle impediments to scaling up urban agriculture beyond self-provisioning, despite land not being an insurmountable barrier. These include taxation systems assuming agriculture is a strictly rural activity, inadequate knowledge sharing among urban producers, limited access to soil, water, and seeds, and a lack of incentives for landowners. Achieving 10% of the city's commercial fresh vegetable demand requires significant policy and program initiatives in five key areas, including governance, coordination, and financing.
