A multi-method study assessed food security and perceptions of nutrition in the Monteverde Zone, Costa Rica, using anthropometric assessment, semi-structured interviews with mothers, 67 Radimer/Cornell Scales, and a focus group. Food insecurity, particularly Adult Food Insecurity, was prevalent across all communities. Despite high nutritional knowledge, a lack of quality nutrition was observed due to economic limitations. The focus group positively received the idea of a community garden as a solution for better quality and more affordable produce.

World Vision Ethiopia launched a Micronutrient Program in October 1998 to improve the micronutrient status of mothers and children, promoting vitamin A–rich food production. By 1999, 11,708 backyard gardens, 275 school gardens, and 77 community gardens were developed, contributing to household food security and income. The program found that vitamin A–rich vegetable production was well accepted, sustainable, and cost-effective, but faced challenges with the availability and cost of imported seeds.

The International Symposium on Plant Health in Urban Horticulture, held in Braunschweig, Germany, from May 22 to 25, 2000, served as a platform to discuss deficits in the care and development of urban greenery and propose integrated concepts. Urban horticulture comprises diverse elements characterizing urban life, but many stress factors damage these components, and integrated concepts for maintaining and preserving urban green areas are lacking. The symposium aimed to jointly prepare future needs for action for the health preservation of urban green at an international level.

An essay argues that urban agriculture—food and non-food production occurring throughout urban and peri-urban fabric—could improve city dwellers' nutritional status and food security, strengthen food self-reliance and employment prospects, and make survival strategies more effective. It describes urban agriculture as a setting where children, young people, and adults engage directly in safe food production and develop respect for farmers' work, surveys the evolution of cities and green-space use in Europe and North America, presents recent urban agriculture experiences in African, European, and Latin American countries, and advocates urban agriculture as a local solution to social, ecological, political, and economic problems.

This study evaluated the "Nutrition in the Garden" program's effect on students' attitudes and behaviors regarding fruit and vegetables. While students' attitudes towards vegetables and fruit/vegetable snacks became significantly more positive after gardening, no differences were detected in attitudes towards fruit. Crucially, students' fruit and vegetable consumption did not significantly improve, remaining at an average of 2.0 servings per day, which is below national averages and recommendations.

Chinwe Okonkwo · Zenodo (CERN European Organization for Nuclear Research) · Nigeria (Lagos)

A study in low-income Lagos neighborhoods, Nigeria, qualitatively explored the perceived impact of urban vertical farming projects on household dietary diversity. Data were collected through in-depth interviews with 24 household primary food providers participating in vertical farming initiatives and focus group discussions with project facilitators. Participants reported a marked increase in regular consumption of leafy green vegetables, and a "substitution effect" was observed where savings from home production were redirected to purchase other nutrient-rich foods.

A Fall 1997 questionnaire for elementary school teachers participating in a Florida school garden competition found that teachers used school gardens infrequently, with most using them as an instructional tool no more than 10% of the time. However, 97.1% used them for environmental education, 72.9% for experiential learning, and 84.3% reported enhanced student learning. The surveyed teachers had relatively new gardens and lacked or were unaware of educational resources.

William Ted Johnson · Electronic Green Journal · North America

This is a review of Thomas Leo Ogren's book "Allergy-Free Gardening: The Revolutionary Guide to Healthy Landscaping" (2000). The reviewer notes that while the book attempts to quantify plant allergy potential, it overstates the case against many common North American garden species. Ogren's OPALS system for allergy classification considers various factors but lacks a clear explanation of how these factors combine into a single score, suggesting a reliance on subjective estimation rather than scientific objectivity. The book's focus on planting only female plants to achieve an "allergy-free" garden is criticized for undermining efforts to consider the holistic value of native plantscapes.

This article describes how implementing policy changes in organizations and communities supported physical activity in the Southeast Asian community in Long Beach, California. Case studies from the Families in Good Health program illustrate the components of successful policy development for physical activity. Increased policy opportunities occurred when high levels of five factors were present: program champions were cultivated; strong partnerships were formed; the community gave approval of program results; community leaders were involved; and organizations or resources were ready for policy development.

Angela Moskow · Environment and Urbanization · Cuba

The promotion of urban agriculture in Havana, Cuba, as a response to the acute food scarcity that developed after Soviet aid and trade were sharply curtailed in 1989, is examined through research including interviews with households engaged in urban agriculture. The paper describes the contribution of Havana's 26,000 self-provision gardens to household nutrition and income and to community environmental quality, and discusses lessons that can be drawn from this experience.

Sarah Lineberger, J.M. Zajicek · HortScience · Global

A study (HortScience, 1999) developed a teacher curriculum guide, "Nutrition in the Garden," combining horticulture and nutrition lessons, and tested its effect on children's food preferences and eating behaviors using a pretest/posttest attitude instrument developed by Tom Baranowski and a 24-hour food recall journal. The abstract states that results examine the effects of school gardens on nutritional attitudes and behaviors but does not report specific outcome figures.

A study in Southern Flevoland, Netherlands, from 1994 to 1996, assessed inoculum sources of potato late blight. It found that 74% of early disease foci in commercial potato fields were linked to nearby infested refuse piles. Infected seed tubers, volunteer plants, and infested allotment gardens appeared to be of minor importance for late blight development in potato fields. However, in August 1994, infested organic potato fields became major mid-season infection sources, spreading the disease to adjacent conventional fields.

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 thesis investigates the sanitary risks of using polluted water for urban agriculture in Ouagadougou, Burkina Faso, where vegetables, including those eaten uncooked, are irrigated with such water. The study aims to assess diarrhoea incidence, parasitic infection prevalence, microbiological pollution levels in water, soil, and vegetables, and sociocultural factors. Initial findings indicate that peripheral sectors are more polluted than central ones, and exploited surfaces vary significantly by season. The abstract highlights potential sanitary risks due to pathogenic germs surviving in water, soil, and plants.
