This chapter examines technological innovations in protected and semi-protected urban agriculture cultivation in Cuba. Greenhouse cultivation was initially introduced for import substitution in tourism, with adaptations for tropical conditions and agroecological pest control. Semi-protected cultivation, using shade-providing screens, later replaced protected cultivation as a subprogram, and polycultures have been effectively reintroduced in semi-protected organóponicas. The program is rapidly expanding with government support.

The Santome Area in Saitama Prefecture has practiced circular urban agriculture utilizing plain woods for 300 years, but urbanization, particularly in Kawagoe City and Tokorozawa City, is causing a significant decline in farmland and plain woods. While the Ministry of Agriculture, Forestry and Fisheries and Saitama Prefecture promote urban agriculture and plain wood preservation, the plain-wood-utilizing circular urban agriculture in Santome Area faces specific problems. This paper identifies land systems, including taxation, as a central issue among these problems and examines the possibility of integrated preservation for farmland and plain woods.

The effect of wastewater irrigation on sorghum and maize yields for animal feed production in urban agriculture was studied at an urban farm in San Miguel del Padrón municipality, La Habana province, Cuba. Two treatments, wastewater irrigation (T1) and no irrigation (T2), were compared, with a total net dose of 1775.4 m3·ha-1 of wastewater applied over 31 irrigations. Wastewater irrigation significantly increased grain yields for sorghum (4.29 t·ha-1) and maize (1.73 t·ha-1) compared to the no-irrigation treatment. Sorghum showed better water utilization efficiency than maize.

This paper reports on the multiple impacts that community garden design may have on the subjective well-being of site users, using the capability approach as a normative framework. Qualitative research conducted in five community garden sites in the UK and Ireland in early 2011 yielded new explanations for both sustainable design and well-being. Two key design aspects, agency and dynamic balance, were found to enhance both the sustainability of the community garden sites and the well-being of site users.

This article proposes the "ecology of agricultural labor" as a new alternative characterized by intermediate technology, mass production, local consumption, and recycling agriculture. It illustrates this concept with two examples: natural farming by Jinlei in Zaoqiang County, Hebei Province, and the Little Donkey Citizen Farm in Beijing, China. The study suggests that this approach forms the basis for sustainable development by fostering symbiotic relationships between humans, society, and nature.

A study of soil salinity in irrigated fields used for urban agriculture in a semi-arid region of South Africa. It compares sodium levels (19.3 vs. 9.8), pH (7.13 vs. 6.3) and electrical conductivity ECe (22.1 vs. 7.9 dS/m) between topsoil and subsoil layers, finding that calcium, magnesium and potassium (unlike sodium) were higher in the top than the subsoil layer, while pH and ECe did not differ significantly by depth overall. By irrigation method, basin irrigation produced the highest accumulation of calcium, magnesium, potassium and sodium, followed by drip and then sprinkler irrigation, with the same ranking (basin > drip > sprinkler > control) for pH and ECe; sprinkler irrigation was the only method showing higher pH and ECe at 10-20 cm depth than at 0-10 cm. The study concludes that irrigation is increasing soil salinity and points to the need for sound irrigation water management, particularly appropriate irrigation scheduling.

A book chapter surveying the state of urban agriculture in African cities. As rural-to-urban migration increases demand for food quantity and quality, urban agriculture is described as able to contribute to livelihoods and economic growth; horticulture is called a vital economic sector, citing figures such as Côte d'Ivoire's fruit and vegetable exports to the EU exceeding 360,000 tons, Burkina Faso's 2007 green bean exports of over 925,000 tons, and Mali's tomato and okra production reaching over 17,000 tons and 8,600 tons respectively. The chapter also notes that the horticultural sector, including urban agriculture, faces pest attacks and phytosanitary problems and must comply with pesticide regulations and quality-control (traceability) standards required by export markets.

A study assessing indigenous arbuscular mycorrhizal fungi (AMF) community structure in roots and soil of Plantago major (plantain) growing on trace-metal (TM)-contaminated versus uncontaminated sites, selected based on a survey of TM concentrations (As, Cd, Cu, Pb, Sn, Zn) in community garden soils in Montreal, Canada. AMF community structure was analyzed using PCR-DGGE, cloning and sequencing, and direct sequencing. Native AMF diversity, measured by the number of AMF ribotypes, was decreased in TM-polluted soils and plant roots compared with unpolluted sites, and community structure was altered by TM contamination. Various Glomus species along with Scutellospora aurigloba and S. calospora were the most abundant ribotypes in unpolluted soil, while G. etunicatum, G. irregulare/G. intraradices and G. viscosum occurred in both polluted and unpolluted soils, and G. mosseae together with unidentified Glomus ribotypes (B9, B13) dominated in TM-polluted sites. The predominance of G. mosseae at metal-polluted sites is interpreted as suggesting tolerance to TM stress and potential use for phytoremediation.

Urban and peri-urban agriculture (UA) significantly contributes to the total food requirements of cities, especially in southern cities of the developing world. This review describes agronomic issues unique to UA and identifies possible interventions to address them. Growth-limiting and growth-reducing factors in UA include water availability, nutrient supply, soil degradation, pests, and soil pollution. Addressing these constraints requires action at both field and municipal or regional levels.
