"Study Abroad in the Neighborhood" involves pre-service teachers visiting local families to learn Spanish language and culture. "Environmental Regeneration through Permaculture Food Gardens" focuses on pre-service teachers and children constructing school gardens linked to curriculum, food cultures, and health. These community contexts aim to enhance pre-service teachers' cultural and environmental awareness of local injustices.

Sarah Yixin Zhang, Zhang Zhi-xing · Journal of the Association for Information Systems · China

This study investigates how Community Supported Agriculture (CSA) pioneers in China use microblogging technology to engage members and develop their communities. CSA is a sustainable agriculture model where members support farms and share risks, making trust-building crucial. Microblogging platforms provide farmers with a channel to communicate updates, address member problems, and facilitate interactions among CSA members, especially when frequent farm visits are not possible. The study analyzed microblog posts from China's first CSA farm.

This paper discusses rainwater management in the "niayes" zone of Dakar, Senegal. This area is characterized by agricultural depressions with typically high groundwater levels, but a recent drop has turned some into runoff-gathering sites, used for urban agriculture among other services. However, two acute problems are observed: hydrological drying due to insufficient rainwater refill and urbanization of these bottom-lands. Furthermore, decreasing pluviometry exacerbates nuisances like floods and malaria.

A 2010 questionnaire survey of 30 backyard chicken flock-keepers in the Greater London Urban Area found that while chickens generally had conditions for natural behaviors, most owners did not comply with regulations on catering waste feeding. Disease prevention measures were rare, and a lack of avian and zoonotic disease knowledge among owners was observed, indicating implications for disease control.

Dan Rabinowitz · International Journal of the Commons · Israel

This article extends Common Pool Resources (CPR) theory to residential complexes, defining Residual Residential Space (RRS) such as courtyards and lobbies as a new sub-set of CPR. Based on findings from three types of RRS in Israel, the study suggests that legal instruments alone are insufficient for regulating such spaces. Effective regulation requires alignment with popular framings of RRS, local sensibilities, and stakeholders' community expectations.

This research focused on the re-imagining of identity through volunteer work at Spitalfields Community Farm in Tower Hamlets, London. It specifically investigated how Bangladeshi-Londoni diaspora volunteers contributed to creating this urban rural space and how, through their imagining of this space, they consciously sought to remember their homeland while establishing a new sense of identity in London.

程存旺, 孙永生, 石嫣, 温铁军 · 绿叶 · China (Beijing)

This paper discusses the importance of ecological civilization in China's national development strategy, as highlighted by the 18th National Congress. It argues that Beijing's agricultural work should shift from industrialization to "social agriculture," moving beyond traditional GDP-focused strategies from 1956 and 1996. The paper advocates for promoting urban agriculture that combines citizens and farmers, aligning with ecological civilization and drawing on domestic and international transformation experiences.

Indrė Gražulevičiūtė–Vileniškė, Jurga Vitkuvienė · American Journal of Tourism Management · Lithuania

This research addresses the threat of rapid urban expansion to valuable rural heritage, specifically Lithuanian manor residencies, which are historically agricultural but increasingly affected by urban growth. The study aimed to develop interdisciplinary guidelines for managing these manor residential ensembles within urbanized areas. Methods included literature analysis and photographic surveys of manor residencies in Kaunas, Lithuania, also considering their connection to tourism.

· · Global

This paper discusses the unsustainable uni-directional flow of food and nutrients from rural areas to cities, which are then discharged as waste, causing pollution and nutrient depletion. Citing historical examples from Rome and London, and contemporary observations of sewage plumes in coastal cities worldwide, it highlights how valuable nutrients are lost to the sea. The paper argues that creating sustainable cities requires re-evaluating nutrient flows between urban and rural areas and understanding urban metabolism.

Chiara Tornaghi · · United Kingdom

This academic-activist research on grassroots urban agriculture initiatives, focusing on four projects in Leeds, UK, found that local and regional institutions have limited ability to respond to these new demands. Planning traditions constrain institutions, failing to create flexible public spaces. Consequently, short-term solutions are found in "loose spaces" or ad-hoc negotiations, but these remain emergency or residual practices, highlighting challenges for urban public space management.

Bruntfield, Jaclyn Rose · Scholars Archive - University at Albany (University at Albany, State University of New York) · United States (Columbia County, NY)

This abstract discusses the increased public scrutiny of food origins in the U.S. and the growing demand for alternatives to the mainstream food system, as evidenced by more farmers markets, organic products, and Community Supported Agriculture programs. It notes that post-WWII industrialization of food production, while providing inexpensive food, has potentially compromised people's relationships with food. Currently, only one percent of Americans identify farming as their primary occupation.

Anthony M. Fuller, Theresa Schumilas, Zhenzhong Si · Digital Commons - Lingnan (Lingnan University) · Canada; China

This presentation examines innovations and contradictions in Community Supported Agriculture (CSA) in Canada and China, where farmers pursue economic, social, and ecological goals. It describes the evolving CSA movement in Canada and identifies three paradoxes, including the economic paradox of market-based social change, questioning if CSAs can maintain their alternative nature or if co-optation is inevitable.

Shengzhong Chen · Guangdong nongye kexue · China (Guangzhou)

This study analyzed the development conditions, process, characteristics, and barriers of urban agriculture in Guangzhou City. It showed that while urban agriculture in Guangzhou has formed functions such as production, technology demonstration, ecological barriers, and leisure services, it faces internal and external development barriers including a decline in agriculture's status, expansion of urban land, labor shortages, and environmental pollution. These barriers hinder the healthy and sustainable development of urban agriculture.

Alisson Amorim da Silva, Sammy Sidney, Rocha Matías, Rafaela Ribeiro de Souza, Roberto Lustosa Silva, Júlio César Azevedo Nóbrega · · Brazil

The effect of different percentages of cattle manure (0%, 20%, 40%, and 60%) on millet development was evaluated in a greenhouse at the community garden of Corrente city hall, Brazil. The percentage of cattle manure significantly affected the number of leaves, plant height, shoot dry mass, and main root length. A manure dose equivalent to 40% of the total substrate volume was found to provide nutrient amounts closer to the ideal for achieving maximum efficiency in millet's physical variables.

윤희정, 조미경 · · Korea

This study aimed to critically consider and classify new paradigms for urban parks in the 21st century. While urban parks exhibit progressive aspects such as process, openness, productivity, and community space, they face significant criticism regarding the long development period for tree growth, covering open spaces, ecological limitations, economic validity, urban sprawl, underutilization as a low-carbon strategy, and negative consilience with contiguous fields. Based on these critical considerations, the study proposed urban agricultural parks as an alternative.

Coline Perrin · International Planning Studies · France, Italy

Case studies in Provence and Tuscany indicate that planning prescriptions and land-market control are insufficient for protecting farmland on the urban fringe. Farmland is not effectively protected if regulatory approaches are not integrated into a global strategy for agriculture and food based on community involvement. Farmland protection policies are more effective when combining top-down policies with bottom-up initiatives and recognizing the multifunctional character of urban agriculture.

Siqing Chen · APCBEE Procedia · United States

This paper uses a housing development project in the United States to exemplify how civic agriculture can be integrated into urban development through forms like Community Supported Agriculture (CSA), kitchen gardens, and farmer's markets. This integration creates a local food web, enhancing civic engagement and welfare among residents, maintaining landscape authenticity, strengthening ecosystem services, reducing carbon footprint, and promoting long-term sustainability. Civic agriculture represents a transition in agricultural practice from large-scale commodity enterprises to small-scale, self-sustaining civic activities.

Julie L. Self, Amanda Wyatt, Aimee Webb Girard · The FASEB Journal · United States (Atlanta)

This research characterized community gardens (CGs) in two urban counties in Atlanta, Georgia, through semi-structured interviews with diverse garden leaders. The study identified primary barriers to creating and sustaining CGs as leadership constraints, reliable access to natural resources, and unclear regulations. It also found that CGs foster access to fresh food, knowledge, and community connections, with benefits varying by community.
