This paper discusses the Guerrilla Gardening movement, a non-violent direct action practiced by environmentalists to reclaim degraded and abandoned urban areas. The increasing demand from citizens for improved living environments in cities is cited as a sign of change, evidenced by the growing number of guerrilla gardening groups, demand for urban gardens, and the emergence of shared gardens. Guerrilla gardeners advocate for new forms of ownership that rescue public lands from abandonment and degradation.

This study investigated irrigation water management for guava cultivation under urban agriculture conditions at UBPC Celia Sánchez in Habana del Este, Cuba. Using a drip irrigation system with fixed doses and intervals, results showed that initial irrigation doses need adjustment based on crop demands. During the development period, the used doses and irrigation frequencies were acceptable, with an average 90% irrigation efficiency. Maintaining high soil moisture significantly impacted guava yield and size, producing more large fruits and yields up to 36.7 t/ha.

It suggests that Niccolo Machiavelli would have found the complex politics, emotions, and diverse personalities in the community garden challenging, observing alternating forms of governance such as benign dictatorship, bureaucracy, and popular democracy.

Martina Předotová, Eva Schlecht, Andreas Buerkert · Nutrient Cycling in Agroecosystems · Niger (Niamey)

An experiment quantified nitrogen and carbon losses from animal manure stored in urban vegetable gardens in Niamey, Niger. During a 3.5-month dry season experiment, cumulative gaseous nitrogen losses were highest (0.11 g kg−1 manure DM) in the uncovered control, decreasing by 72% with plastic sheet roofing and 50% with roofing plus rock phosphate. In a second 3.5-month rainy season experiment, carbon losses from the control were 164 g kg−1 manure DM, reduced to 77% and 65% of the control by roofing and roofing plus rock phosphate, respectively. Leaching losses during the rainy season were only observed for the unroofed control.

This descriptive article on composting states that about half of household waste consists of food remains, vegetable, and garden waste, and that over 50% of waste is organic material that ends up in storage sites, cesspools, or is burned, causing significant pollution. As an alternative, it describes transforming organic material through microbial, biochemical, chemical and physical processes into a humus-like material called compost. Producing quality compost requires managing the pile's dimensions, humidity, structure, and composition so decomposition agents (bacteria, fungi, mites, springtails, woodlice, worms, millipedes) have an ideal, nutrient-rich substrate; these agents need nitrogen ("green" elements, from food remains, cut grass, and green leaves) alongside carbon ("brown" elements, from wood chips, dry leaves, and sawdust), maintained at roughly a 30:1 brown-to-green ratio through alternating layers. The article states that producing compost in schools can bring the whole school community together for environmental work, contributing to natural resource recirculation, community education about compost's benefits, a shift in cultural attitudes toward waste, reduced food-remainder volume from school canteens, student involvement in extracurricular activities, and fertile soil for school gardens and planting. The abstract text is truncated at the end, cutting off its description of composting's benefits as a fertilizer.

This study surveyed producers in urban and peri-urban agriculture settings in Cuba to identify low-growing plant species commonly used for hedges in agroforestry systems. The surveys revealed 13 species across 9 families utilized as hedges. In the City of Havana, Marpacifco (Hibiscus rosasinensis), Bugambilia (Bougainvillea glabra), and Muralla (Murraya paniculata) were most frequently used, while in rural areas, Cardona (Euphorbia lactea), Tuna (Opuntia dillenii), and Itamo real (Pedilanthus tithymaloides) were more common.

Carla Ellen Lima Lemos, Eduardo Sevilla Guzmán · REVISTA BRASILEIRA DE AGROECOLOGIA · Argentina

A research note from Rosario, in southern Santa Fe province, Argentina, focused on migrant groups who moved to Rosario from Argentina's northern provinces over the past twenty years, some from the historical Guaraní cultural sphere, bringing agricultural work experience along with their language. Building on a history of resistance to industrial models of nature management through the Ligas Agrarias and, after repression under military dictatorship, work in traditional subsistence gardens within popular cooperativism, the paper sets out to open a line of research at CEPAR testing the hypothesis that Guaraní management forms exist in Rosario's community organic gardens. If supported, this could be termed a "Rosario agroecological gardening style"; the urban agriculture model that has taken shape is described as arising from the interaction between immigrant groups' knowledge and modern conventional agronomic technique.

This study, conducted from March to September 2002, investigated the growth response of five native plant species (Chrysanthemum zawadskii, Sedum middendorffianum, Thymus quinquecostatus, Allium senescens, Dianthus superbus) to artificial substrate soil depths (5 cm, 10 cm) and irrigation periods (non-irrigation, 1, 2, 3 weeks) for rooftop gardens. Sedum middendorffianum and Allium senescens showed 0% mortality regardless of soil depth and irrigation, making them highly suitable. Chrysanthemum zawadskii, Dianthus superbus, and Thymus quinquecostatus generally performed better with 10 cm soil depth, suggesting a minimum viable depth over 10 cm for these species.
