This research examined the cycle of poor nutrition in the Frog Hollow neighborhood, Hartford, Connecticut, an urban food desert characterized by limited access to affordable, healthy foods. It argues that the growth of farmers’ markets, community-supported agriculture, and community gardens has reintroduced affordable, attainable healthy foods to the neighborhood. This introduction of locally grown produce at affordable prices has enabled the Frog Hollow neighborhood to begin addressing food insecurity.

This is a review of Robert Carriker's book "Urban Farming in the West: A New Deal Experiment in Subsistence Homesteads", which examines the Division of Subsistence Homesteads (DSH) program in the American West. The DSH, established in 1933 by the New Deal, aimed to redistribute population and support self-sufficient homesteads. Carriker's work offers a balanced perspective on the program, noting that "confusion over disparate objectives" and bureaucratic conflicts ultimately undermined its goals.

This field-based research in Lusaka, Zambia, examines the impact of climate change and urban governance on urban agriculture, which serves as a source of food and income for poor households amidst deteriorating economies. The study finds that urban agriculture is often excluded from urban development and planning policy, posing significant challenges for small-scale farmers to achieve food security. A lack of policies supporting the urban poor, combined with climatic changes like drought and flooding, makes it difficult for households to adapt to the changing urban environment.

An ethnographic study conducted in summer 2010 at HOPE community garden in Parkdale, Toronto, explored how collective belonging is built. The research found that differences and interpersonal conflicts within the garden were embraced as opportunities to strengthen community cohesion. Contrary to romanticized views of harmonious community gardens, the study revealed that conflicts, negotiation of differences, and institutional practices of inclusion and anti-discrimination significantly contribute to a successful and inclusive community project.

Mahbubur Meenar, Brandon Hoover · Journal of Agriculture Food Systems and Community Development · United States (Philadelphia)

This paper examines urban agriculture (UA) projects' role in addressing food insecurity in lower-income neighborhoods of post-industrial U.S. cities, using Philadelphia as a case study. While UA projects are vital, findings indicate concerns regarding their geographic, economic, and informational accessibility, social exclusion, and spatial mismatch between participants and neighborhood demographics. Challenges also exist in distributing fresh produce to impoverished populations and UA's economic contributions in underprivileged areas.
