This descriptive analysis identified gentrifying areas in Vancouver, Calgary, and Toronto, Canada, from 1996–2006 and 2006–2016, to determine the prevalence of greening interventions. The study found that greening, including parks, cycle lanes, and community gardens, frequently occurred before, during, and after gentrification. These results indicate that greening is common in gentrifying areas throughout the gentrification process, suggesting a need for a broader understanding of the relationship between urban greening and gentrification.

Wenhao Zhu · Highlights in Science Engineering and Technology · United States (Chicago)

This paper focuses on the characteristics of vertical farms, using The Plant vertical farm in Chicago as an example to describe its design and performance, and analyze its advantages and design principles. The success of The Plant is attributed to saving raw materials and waste disposal costs through waste utilization, staggered electricity consumption, and insulated structures to maximize energy cost savings. However, while small-scale pilot projects of vertical farms have achieved some success, many constraints remain for scaling them up due to high construction and operation costs and high technical levels.

Pascale Joassart-Marcelli's book "The $16 Taco" examines how food and power intersect to create landscapes of hunger and plenty in U.S. cities, using San Diego as a case study. It argues for the centrality of food in broader structural issues of social, political, and cultural inequalities, which manifest as material inequality. The book explores the impacts of food apartheid, a system of segregation that prevents certain groups from accessing nourishment, and explains the role of racist real estate practices in devaluing neighborhoods of immigrants and people of color.

This paper discusses how record-high inflation rates and skyrocketing food prices in Canada exacerbate food insecurity, defined as inadequate food access due to financial constraints. Food insecurity is identified as a strong predictor of poor physical and mental health, higher mortality rates for those with chronic conditions, and increased healthcare utilization and costs. The paper suggests a comprehensive approach combining short-term solutions like community gardens and long-term policy interventions to address the root cause of inadequate income.

The research involved a literature review, identification and contact with local institutions, and an electronic questionnaire that received 34 responses. Findings highlighted the vitality of associations, the importance of national policies (PNAE, PRONAF) and territorial strategies (SPG, CSA), and the relevance of local instruments like Trilha da Agroecologia and Rede Sisal.

Seohyun Kim, Carlos Almeida Peña · Journal of Student Research · United States

This study critically evaluated existing initiatives like SNAP, HFFI, and urban agriculture for addressing food deserts in the United States, which affect approximately 19 million individuals. Through a literature review and interviews, the research found that these programs, while offering some positive impact on food insecurity, largely fail to directly address the fundamental issue of distance and systemic accessibility to supermarkets. The study proposes enhancing public transit and online delivery platforms as comprehensive solutions.

This GIS-based study of Kalamazoo, Michigan, analyzed how accessibility to different types of food access points — full-service grocery stores, farmers markets, community gardens, food pantries, and convenience stores — differed between low-income and higher-income census tracts. All full-service grocery stores were accessible via bus routes, but 11% of residents in low-income areas lacked adequate access, living beyond the 0.25-mile walkable distance to bus routes. "Positive" access points such as community gardens, food pantries, and farmers markets were found to be concentrated in areas that already had grocery store access, whereas "negative" access points — convenience and dollar stores, which provide lower-quality, highly processed food — filled the access gap in lower-income areas instead. More than twice as many low-income residents had walkable access to convenience stores as higher-income residents, with 81% of those convenience stores located within low-income tracts.

A book chapter introduces the people behind new urban agriculture and food systems innovations emerging in cities across the United States. These innovators come from all walks of life, and the ways they envision and implement more decentralized urban and peri-urban food systems are as varied as the people themselves. Their stories raise questions about which food systems innovations are most likely to create win-win outcomes of improved food security and improved sustainability. A transformation of the conventional food system is already under way, even in cities with less than optimal growing conditions, but much more remains to be done.

To identify attributes that influenced consumers' choice of locally grown food sources during and after the COVID-19 pandemic, this US study estimated willingness to pay (WTP) across sources. Respondents valued Freshness, Accessibility, Variety, and Risk Shift attributes, in that order. Community-supported agriculture (CSA) had the lowest WTP among the sources examined, and respondents weighted CSAs' general weaknesses more heavily than their advantages when choosing where to buy. However, increasing levels of community outreach positively affected the probability of choosing CSAs over other sources.

Hantz Woodlands, a large-scale tree farm on Detroit's east side, acquired roughly 2,600 parcels and still holds about 2,000. It bought an initial 1,550 parcels for $540,000 and later resold about 10% of its holdings for $9.5 million — nearly nine times its original cost — while paying only $7,035 of the $33,110 it owes in blight-violation fines. Critics note the Detroit Land Bank Authority never reclaimed a single Hantz property despite missed deadlines, even as it repossessed land from ordinary residents who fell behind.
