Gail Feenstra, Christopher Lewis · California Agriculture · United States (California)

A survey of farmers' market managers in California indicated that farmers' markets provide growers with opportunities to expand their businesses through new market venues, value-added products, and connections with agritourism. Rural markets offered strong community support and tourist links, while small-town markets showed the most new vendors and room for growth. Metropolitan markets, though harder to access, yielded the highest gross sales and increased demand for value-added products.

A 1999 study tests whether membership activities of Community Supported Agriculture (CSA) farms in Vermont, US, generate utility directly. Based on survey data from Vermont, it finds that both time spent picking up produce at the farm and time spent cleaning and putting away produce at home yield utility directly, and that the direct utility from picking up produce is greater than that from cleaning and putting it away.

This study gathered information on the potential contribution of non-timber forest products to the food system of developing countries. Natural plant communities normally contain about 10% native vascular species that can be edible, and this proportion can rise to 20-30% in disturbed habitats, or 30-90% when only weeds are considered. Point-sample frequencies of edible individuals recorded along transects in suburban Austrocedrus chilensis forests near Bariloche, Argentina, ranged from 15% to 66%. The probability of finding at least one edible plant in a random 0.25 m² sample (calculated from n=317 samples) was 0.675, rising to near 1.0 when calculated per hectare. In western Patagonia, the number of exotic edible weed species exceeds 90. The mean available edible biomass in vacant lots in Bariloche was 1,253 ± 392.8 kg/ha, based on 193 samples of 1/4 m² each. The study includes a table of quantitative frequencies for edible weeds and a list of 60 native food plants from Patagonian forests.

Artificial planting soil layers used in settings such as rooftop gardens typically have a two-layer structure: a coarse drainage layer and a planting layer. Assuming no irrigation, this study examined the required layer thickness based on soil physical properties and weather conditions. Using 30 years of rainfall records for Tokyo, the logarithmic cumulative distribution of the number of days between rainfalls was well fitted by a normal distribution, with the number of days between rainfalls corresponding to 95% and 99% occurrence probabilities being 29 and 64 days, respectively. Numerical calculations for a two-layer system with a 100 mm lower layer examined the relationship between layer thickness and the time until the planting layer wilts on average from initial moisture; at 99% probability, the required planting layer thickness was 236 mm, roughly half the 424 mm required for a single-layer system.

This study used a Geographic Information System to analyze the location of allotment gardens for elderly users in Gifu City, Japan, measuring both direct distance and road distance from users' homes to the gardens, and ran simulations of changes to garden provision. Increasing the number of garden plots and changing the composition of users shortened the user distance to some extent, while newly opening gardens in the city center — where none previously existed — greatly shortened the user distance.

This study focused on consumer benefits, specifically cost savings, from Community Supported Agriculture (CSA) membership. It measured quantities of produce in weekly shares for three CSA farms in Massachusetts and calculated retail values. Cost savings, determined by the difference between share prices and retail values for organic produce, ranged from 60% to 150% of share prices for the studied CSA farms.

Godfrey D. Mudimu, Shepherd Siziba, Benjamin Hanyani‐Mlambo · OpenDocs (Institute of Development Studies) · Zimbabwe (Harare)

This study in Harare, Zimbabwe, examined the socio-economics of urban crop production on municipal lands, cultivators' views, and land use conflicts. Urban agriculture, a widespread practice for subsistence maize and food security, is not supported by planners and conflicts with urban land use provisions. Findings revealed a serious lack of environmental concern among cultivators, with most ignoring stream bank regulations and lacking knowledge of environmental effects.

F.E. Trainer · International Journal of Sociology and Social Policy · Global

This paper presents the "limits to growth" perspective, arguing that current living standards in rich countries are globally unsustainable. It criticizes profit maximization and market forces as inappropriate for the needs of the world's poor, and explores how to reduce per capita resource use and environmental impact through small-scale, self-sufficient economies. It suggests that access to communal property and services should replace income as the means to a satisfying life, and mentions the role of community gardens and workers in saving towns.

In Spring 1998, the University of Florida hosted a children's garden competition for approximately 100 elementary schools across Florida. The competition required schools to establish or use an existing garden and for teachers to integrate it into classroom instruction. A random sample of 500 students from participating schools completed an environmental attitude survey at the beginning and end of the competition, and teachers also completed a survey on garden use and its effect on students.

This paper reviews the types and roles of community gardens, which are managed by community members and contribute to Local Agenda 21 planning and sustainable communities. It presents a case study of a community garden in Western Australia, analyzing lessons learned and the potential contributions of such gardens to physical, ecological, sociocultural, and economic sustainability. Community gardens produce fresh organic food, create community spaces, and disseminate community science.

Ren Azuma · Journal of Rural Problems · Japan; Europe

This paper examines the potential for recreational use of farmland by comparing dual land use policies between Japan and Europe (mainly the UK, Germany, and the Netherlands). While Europe has not considered allotment gardens as dual farmland use, Japan is promoting them for both recreation and agricultural production through new legislative measures. Additionally, small-scale caravan sites using farmland are exempt from strict planning controls in many European countries to promote recreational use, but Japan lacks an equivalent. In conclusion, the paper suggests that Japan needs to introduce or further expand dual farmland use policies for recreation and agricultural production in these three policy areas.

A 3-year study in two elementary schools investigated the caries preventive effect of wild tea (tsaang-gubat) among schoolchildren. The experimental group drank one cup of tea daily for 17 months, prepared from fresh school garden leaves. Results indicated that wild tea is an effective caries preventive agent, showing a 75.67% decrease in caries incidence, though an increase in the third year was attributed to irregular consumption and reduced tea fluoride content.

This paper analyzed the relationship between farmhouse management conditions and land possession, and agricultural land use design problems for regional agricultural development. Findings indicate that nuclear farmhouses in suburban and plain areas tend to acquire concentrated land, while those in hilly and mountainous areas do not efficiently possess farmland. It is necessary to improve farmland possession and use by lending inferior farmland from small farmers to nuclear farmhouses. In suburban areas, farmers show little intention to lend land for allotment gardens, requiring eased regulations and support measures. In hilly and mountainous areas, farmers' intentions to lend land are linked to management conditions and possession forms, reconfirming the need for regional zoning planning.

Based on a comparison of allotment gardens in local cities versus metropolitan areas and on-site inspection of several gardens, this paper proposes a facilities and management policy for allotment gardens in local urban areas of Japan. It finds that in local urban areas most allotment gardens are located in suburban areas, whereas in metropolitan areas they are mostly located downtown; even the simplest garden type is expensive in metropolitan areas, while some enriched-type gardens with modest fees exist in local areas. It also discusses the relationship between how allotment gardens are evaluated and their facilities and management, concluding that local-area garden managers need dedication and users need to communicate with managers, guides, and other users.

Using survey data collected in 1994 in Korogocho, one of Nairobi's slum areas in Kenya, this study examined whether access to farmland influences a household's food situation. Access to land had a positive impact on urban households' overall welfare, but not necessarily on their food situation. Households with access to a rural plot appeared better off in terms of self-reported food situation than households without any land access, and access to rural land appeared more favorable for food situation than access to urban land alone. Among the very poor households in Korogocho who claimed access to rural land, half did not actually use that land themselves.
