This paper conducted a comparative analysis of peri-urban agriculture in Lisbon and London to assess its contribution to migrant social inclusion and urban biodiversity. The study found that social inclusion patterns are city-specific; for example, Cape Verdean urban farming communities in Lisbon strengthen community bonds but do not necessarily lead to better integration into wider Portuguese society. Migrant urban farmers contribute to broadening biodiversity, primarily in Lisbon and to a lesser extent in London.

This research analyzed user satisfaction and preferences for hotel rooftop gardens in Seoul and Incheon, South Korea, to propose renovation plans. Customer satisfaction analysis showed that C Hotel and P Hotel in downtown Seoul had lower satisfaction regarding plant numbers and variety compared to H Hotel in Incheon. User preferences indicated a desire for multi-functional green spaces that host cultural and community events and offer physical exercise opportunities.

An ethnobotanical study in five peripheral neighborhoods of Santo Antônio do Leverger, Mato Grosso, Brazil, surveyed 135 households and detailed 30 to characterize food plant cultivation. Ninety-seven species from 38 families were identified across homegardens, fields, and empty lots. While some species were common, the similarity between species/varieties across households was generally below 50%, and many had low frequency, revealing a vulnerability to species loss despite social network circulation.

An assessment of Cuban urban agriculture's production and distribution outcomes finds that the most successful subprogram is fresh vegetable production, which has grown rapidly island-wide, while other subprograms remain active but less developed. Distribution occurs through thousands of points-of-sale, MALs, self-provisioning, and MAEs, with social consumption at workplaces, hospitals, and schools. Urban agriculture plays a significant role in improving Cuban diets but has not led to food sovereignty; other outcomes cited include employment generation, environmental benefits, and community building.

The ability of adding 70 plants of seven native wildflower species over two years to augment beneficial insect richness, including bees, butterflies, and predatory wasps, was assessed in New York City community gardens. Bayesian analyses failed to find a strong influence of the native plant additions on beneficial insect richness, even after correcting for prior floral abundance. Butterflies and megachilid bees were found to heavily utilize introduced ornamental and crop flowers in these gardens, even when native flowers were present.

Nigel L. Webb, Harrison Kasumba · Africanus Journal of Development Studies · South Africa

In Ezibeleni near Queenstown, Eastern Cape, South Africa, a sustainable-development framework was used to gather empirical findings on vegetable crop cultivation, covering duration of crop consumption, the value of produce to households, environmental benefits, and social/psychological benefits. Both the scale of cultivation and the benefits obtained were found to be modest, reinforcing prior studies that focused on the actual practice of urban agriculture rather than its hypothetical potential.

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.

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.
