This field survey in the Modder River basin, South Africa, investigated the potential expansion and implications of a rainwater harvesting technique introduced to small-scale farmers. While a rapid spread within home yard sizes was expected, no significant spread to community gardens or beyond was anticipated in the short term. This limitation was attributed to socio-economic constraints, including poverty and a lack of appropriate tools and basic farming skills.

This study surveyed 180 participants from five city farms in Taichung, Taiwan, between March and April 2004, to assess service quality, satisfaction, and intentions. While perceived service qualities were generally good, overall satisfaction was rated as "slightly satisfied," and renewal and recommendation intentions were rated as "slightly agreed," indicating significant room for improvement. Service content and management had significant effects on overall satisfaction, management on renewal, and service content on recommendation.

This paper compared the successes and failures of two urban creek restoration programs in California: Temescal Creek (initiated nearly 30 years ago) and White Oak Creek (completed about four years ago). Based on the author's success criteria, the more recent White Oak Creek program achieved significant success, while the earlier Temescal Creek restoration did not reach generally acceptable success levels. This difference is attributed to changes in management and scientific practice over 30 years, including substantial changes in the legal basis for restoration, improved monitoring requirements, and the critical role of properly engineered low flow distribution structures.

Jean-Noël Consalès · Rives méditerranéennes/Rives méditerranéennes · Europe

This study examines allotment gardens in Marseille, Genoa, and Barcelona and finds that, although urban agriculture is potentially at stake in these cities, allotments struggle to establish themselves within complex urban contexts. Their actual function appears limited: their social role is often overestimated, while their environmental and landscape significance remains largely neglected.

Rachel Slater · Development Southern Africa · South Africa

This study examined urban agriculture (UA) in Cape Town, South Africa, focusing on its contribution to low-income households. It found that UA's contribution to income generation and expenditure substitution is limited. However, UA is important to women in low-income households in ways less directly related to monetary gain, being used for empowerment, establishing social networks, symbolizing a sense of security, and encouraging community development.

Candan Kuş · · Turkey (Ankara)

A study in Yenimahalle District, Ankara, evaluating multiple schools including 80 primary schools, assessed the importance of school gardens and their place within the urban open-green space system. The findings revealed that many school gardens were unsuitable for use by teachers and students, being narrow, containing only ceremonial areas and a few plants, and lacking sufficient furnishing elements. It was also observed that additional buildings further narrowed school gardens, and insufficient attention was given to recreation areas, sports areas, and green spaces.

A diagnostic study was conducted on the conditions of urban gardens, their producers, and families in 20 gardens across five localities in the "Boyeros" and "Arroyo Naranjo" municipalities of Havana, Cuba, between December 1998 and March 1999. While the garden agroecosystems showed satisfactory biodiversity, general knowledge of biological technologies in sustainable urban agriculture remained relatively low. None of the surveyed plot owners consciously knew or used vermiculture, pisciculture, biofertilizers, biopesticides, or biostimulants, and almost half did not consciously use crop rotation.

This paper examines the "myth of the urban peasant" in Russia, which suggests urban households survive economic collapse through subsistence agriculture. Based on official and survey data analysis, it shows that while many urban households grow food, those with low incomes are least likely to do so, and subsistence production complements rather than replaces paid employment. Furthermore, those who grow their own food work long hours for little return, spending no less on purchased food than those who grow nothing.

Dick Foeken, A. Mboganie-Mwangi · Leiden Repository (Leiden University) · Africa

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.

A. Mboganie-Mwangi, Dick Foeken · Leiden Repository (Leiden University) · Kenya (Nairobi)

A 1996 study in Nairobi, Kenya, compared the food security and nutritional status of low-income households engaged in urban agriculture with those not farming. It found that urban farmers primarily produced for home consumption and faced theft as a major problem. While the Undugu Society Urban Agriculture Project (USUAP) group showed better food situations and higher energy and protein intakes than other groups, all three groups had inadequate energy intake on average. The long-term beneficial effect of urban agriculture on nutritional status was negligible.
