This paper explores urban pig farming as a specific form of urban and peri-urban agriculture (UPA). It uses a design-based research strategy, drawing on the 'City Pig' study (2009) from Delft University of Technology, to identify the potential benefits of urban pig farming and assess how un-built design projects can inform future real projects. A significant limitation is that the study concerns virtual, un-built design proposals.

A literature review of international research on short food supply chains (SFSC) and their impacts, combined with findings on the types already established in Hungary. SFSC consumers tend to be more highly educated than average; traditional forms such as farmers' markets attract older people while newer forms such as community-supported agriculture and web-based value chains attract younger people. The review finds that clear scientific evidence of SFSCs' positive environmental, social or economic impact is not always available, and in some cases traditional food supply chains prove cheaper and more environmentally beneficial, concluding there is no generally preferable SFSC solution given their heterogeneity.

This study examined the diversity of alternative agri-food networks (S3A) supplying collective catering (school and institutional canteens) in France, particularly the Île-de-France region, and their respective capacity to reestablish a link between food and urban agriculture. Distinguishing S3A based on proximity relations tied to the region's urban agriculture from S3A built on extended networks spanning distant production and consumption sites, the results show that whether Île-de-France farm products are introduced into canteens depends, beyond the level and nature of local supply, on multiple other local factors such as the existence of producer-referencing networks and the state of kitchen equipment and labor resources.

This study evaluated consumer perceptions of organic and locally grown produce at farmers' markets in North Carolina, focusing on the Piedmont Triad region. Using qualitative methods with focus groups from five locations, preliminary findings showed consumers distinguish local and organic foods only by labeling. Participants had limited knowledge of organic certification, and while most purchased more local foods, they were willing to pay up to 100% more for organic food.

Organic foods, initially championed in the early 20th century, gained commercial significance in the 1990s as consumers sought to avoid chemical residues and improve nutrition. However, scientific support for nutritional benefits and significant reductions in pesticide residue risks is weak. While organic crops reduce chemical runoff, they require more land due to lower yields, leading to the promotion of "local" foods and urban agriculture.

A study modeling city food footprint using supply-and-demand data, applied to Beijing over time. Beijing's food footprint grew from 11,800 km2 in 1993 to 29,400 km2 in 2010, about 1.8 times the city's territorial area, while per-capita food footprint stayed roughly stable at 0.127 hectares. The paper concludes that continuing population growth and shrinking arable land will force Beijing's food footprint further outward, and argues the city needs a different development strategy that strengthens local food supply through urban and peri-urban agriculture.

A Chinese paper arguing that high logistics costs are the main driver of the exorbitantly priced agricultural products criticized by urban residents, caused by the many distribution links and losses inherent to agricultural products. It proposes shareholding leisure agriculture—drawing on advantages in production scale, capital, technology and information—as a carrier for integrating rural logistics resources and directly linking agricultural production with sales.

A discussion piece noting that peri-urban farming, historically important in the United States, is now less prominent. It states that growing interest in local food production has focused attention on urban agriculture and vertical greenhouses, but that high land and energy costs, limited access to appropriately sized and shaped open space, and shading from surrounding tall buildings constrain urban agriculture options, and argues that peri-urban farming in traditional horizontal greenhouses can be a better alternative to vertical greenhouses.

This study investigated the ability of urban agriculture (UA) to decrease food-related greenhouse gas emissions, using a life cycle analysis of tomatoes, produce surveys in East Anglia, and household surveys of 183 UA-practicing households. It found that UA participation can reduce an individual's tomato consumption emissions from 52.4 kg CO2e/yr to 11.2 kg CO2e/yr. This reduction amounts to 44% from a non-UA, low-emission diet and 78% from a supermarket diet.

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.

This study analyzed data from 1,994 US adults from the National Cancer Institute's Food Attitudes and Behaviors Survey to assess the use of farm-to-consumer venues for purchasing fruits and vegetables. It found that 27% of grocery shoppers reported at least weekly use of these venues during summer. Older adults and those in the Northeast were most likely to use them weekly, with no differences observed by sex, race/ethnicity, education, or income.

This report examines the weakening relationship between agriculture and food, leading to market failures, reduced competitiveness, and information deficiencies, with processed foods and supermarket purchases dominating. It focuses on direct sales and Community Supported Agriculture (CSA) as methods to realize "eating habits of volitional selection." These regional markets foster trust and traceability, contributing to food safety, and the study introduces examples from 12,000 direct sales stores, female farmer enterprises, and the Pal System Consumers Cooperative Union.

Amy Courtney, founder of Freewheelin’ Farm, a community supported agriculture (CSA) program, delivers shares by bicycle-drawn trailer. Courtney, a 1997 graduate of UCSC’s Apprenticeship in Ecological Horticulture, started the farm in 2002 with minimal motorized vehicles, utilizing used equipment and recycled materials. She and her partners continue to haul all CSA shares six miles into Santa Cruz by bicycle. Courtney's work is driven by a commitment to social justice, community health, and cultural vitality. The farm collaborates with "Food, What?!"—a youth empowerment program, and hosts cultural and educational initiatives.

This paper studies how various apples enter a community in London, using the apple as a device to analyze the city-region's food system and its connection to productive land. A multi-level analysis examined four arenas of procurement: mainstream retail (supermarkets), wholesale markets, direct links with producers (CSA box schemes, farmers' markets), and ecologically localized procurement (gleaning projects, community orchards). The study explores how these different journeys are understood and accounted for.

This study used survey data from two US states to answer two questions: what is the maximum distance food can travel and still be considered "local" by consumers, and is "local" equally important across food categories. The research found that consumers' accepted food travel distance may be much shorter than generally believed. Additionally, there is significant variation in the importance consumers attach to "being local" for different food categories, and these differences are related to consumer characteristics.

Bianca Ambrose‐Oji · · Sub-Saharan Africa

This book chapter reviews the role of urban and peri-urban agriculture in food security across sub-Saharan African cities and peri-urban areas, focusing on how the production and collection of indigenous vegetables along the rural-urban continuum contributes to it. Drawing on literature from geography, agriculture, ethnobotany and rural sociology, it defines urban agriculture and the spaces where indigenous vegetables are produced and collected, and closes with a typology for understanding the range of spaces involved in indigenous vegetable production and harvest, without presenting new empirical data.

This study determined which transportation option -- farmer delivery or customer pick-up -- consumed less fuel and emitted less CO2 for an Iowa community-supported agriculture (CSA) enterprise. The method used the CSA farmer's actual delivery route(s) including customer addresses, the type of delivery vehicle used, and a hypothetical central pick-up location and time, calculating mileage via Mapquest and fuel/emissions using Bureau of Transportation Statistics and EPA data across four vehicle categories: Ford Ranger, Dodge Caravan, Toyota Prius, and U.S. average passenger vehicle fuel economy. Delivery using a Toyota Prius resulted in 2.77 times lower fuel usage and CO2 emissions than customer pick-up using U.S. average fuel economy; however, even if all CSA customers used a Toyota Prius for pick-up, farmer delivery remained more fuel efficient, though only by a factor of 1.35.

This paper critiques the current literature on local food systems, which are promoted for local economic growth and reduced environmental impact, but often lack rigorous analysis from a regional science perspective. Using the Porter Diamond framework, it discusses how regional science can analyze local food systems as an economic development tool and assesses their potential environmental benefits.

This paper reviews existing literature on Alternative Food Networks (AFN), discussing their multifaceted foci. AFNs have been presented as a response to conventional agribusiness or a transition towards an alternative era, encompassing short food supply chains, local food supply systems, direct farm retail, and community-supported agriculture. Defining characteristics of AFNs include "fresh," "diverse," "organic," "small-scale," "local," and "sustainable," which contrast with the "processed," "mass production," and "long food supply chains" of conventional systems.

Karin Andersson · · Sweden

This study analyzed Ramsjo gard, the only Community Supported Agriculture (CSA) farm in Sweden, from a sustainability perspective using a mail survey of CSA members and a farm sustainability analysis. The survey found no statistically significant relationship between farmer-member contact and member learning, nor between member learning and changes in food purchasing habits. The sustainability analysis indicated that farmers perceived social and environmental aspects as more sustainable than economic and practical ones.

This book points out that the long-distance food system consumes staggering amounts of fuel, generates greenhouse gases, and compromises food security. Since 1961, the tonnage of food shipped between nations has grown fourfold, with food in the United States typically traveling 1,500 to 2,500 miles from farm to plate. While this system often runs roughshod over local cuisines, varieties, and agriculture, a local-foods movement is beginning to emerge globally.

This study examined whether Community Supported Agriculture (CSA) groups are a broadly accepted or limited alternative food system, based on a household survey in two distinct socio-economic neighborhoods in upstate New York. The survey found that approximately 25% of respondents expressed interest in becoming CSA members, with similar interest levels in both wealthier and low-income areas. However, several factors preventing food demand through CSAs were identified, indicating that these barriers would need to be addressed for expansion.
