Factors influencing primary school teachers' decisions to utilize school gardens in their STEM curriculum were investigated using a mixed methods design in a single school district. Quantitative data was collected from garden resource and teacher self-efficacy surveys, while qualitative data was extracted from in-depth teacher interviews. Overall analyses determined that aspects of instruction and logistics were the most important factors for teachers in their decision to utilize school gardens.

In the late 1980s, Japanese experts seeking a model allotment garden rejected the UK model, perceiving it as low status and in decline, in favor of the German Kleingarten. This paper suggests reconsidering the UK experience, given efforts to rebrand UK allotment gardening within sustainable development and the challenges faced by the Japanese Kleingarten model in the 1990s' changed economic climate.

Motivated by concerns over water and food scarcity and the health threats posed by faecal pollution and malnutrition, this paper discusses the development of a no-mix excreta disposal system that separates urine and faeces. It argues that ecological sanitation systems open up new, constructive sanitation options, particularly in poor peri-urban areas. The purpose of the no-mix system is described as saving water, reducing wastewater treatment problems, protecting groundwater quality, and recirculating nutrients from urine, and the paper addresses these aspects comprehensively.

This paper proposes policies for allotment garden facilities and management, based on a survey of users' consciousness. The survey found that some users rent gardens that do not satisfy their purpose due to a lack of publicly available information about allotment gardens. The paper concludes that garden managers must publicize the purpose of establishing gardens and show eagerness, while users should communicate with managers, guides, and other users.

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.

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.

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.

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.

An online survey was conducted on the KinderGARDEN Web page to investigate children's perceptions of gardening benefits. Children responded via email, reporting on their gardening experiences, learning, and perceived advantages. Results indicated that children positively valued gardening for recreation, and also mentioned educational, environmental, aesthetic, social, and economic benefits. Specifically, 81% felt they learned about the environment, 54% about plants, 31% cited recreation/fun, and 15% mentioned socialization with friends and family.

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.

This research suggests that social objectives primarily drive CSA shareholders' decisions to join, with economic and "club-related" objectives being secondary. While the CSA movement is expected to grow, its emphasis on social objectives, inability to supply food year-round, and the development of size-neutral organic technologies will likely prevent it from becoming a major market channel in the next century.

Godfrey D. Mudimu · Singapore Journal of Tropical Geography · Zimbabwe (Harare)

This study examines the role of women in urban agriculture and perceptions of urban space use for agriculture in Harare, Zimbabwe. Despite its utility in meeting household food needs, urban agriculture is not planned for or supported by urban planners and managers as a legitimate urban land use. The activities of women, who are the main participants in urban agriculture, directly conflict with planning provisions for urban space. The study offers empirical insight on perceptions of space use for agriculture in an urban tropical environment, where conflicts can arise from different perceptions and alternative uses.

This study investigated cadmium (Cd) and zinc (Zn) concentrations in vegetables grown in community gardens on different urban soils. Vegetables from a low-pH urban soil without contamination history showed higher Cd and Zn levels than those from a reclaimed landfill with digested sewage sludge, and also higher than a low-metal, neutral-pH site. Liming on the low-pH site reduced Cd and Zn concentrations in beet, lettuce, radish, and Swiss chard leaves, reaching background levels after four years. The findings indicate that soil pH is more important than total soil Cd and Zn in determining vegetable metal availability.

This paper reviews the wide range of options available to municipalities in the Global South for alleviating or reducing poverty. These options include employment creation, improving low-income groups’ access to justice and protection from crime, and enhancing urban services such as water supply, sanitation, solid waste management, public transport, health care, and education. The paper also outlines how municipal action must encourage and support community-based organizations, NGOs, and the private sector, and how changes in regulatory frameworks for land management, urban agriculture, and housing can contribute to poverty alleviation.
