A report on a rural extension project developed around a community garden run by a women's association in Brazil, based on agroecological principles that center on exchanging traditional, technical and scientific knowledge as a means of interaction between the university, advisors and family farmers. The aim was to strengthen social organization and production processes by combining composting and vermiculture practices with technologies such as irrigation systems and cisterns, using theoretical and practical workshops. Results showed that these activities enabled families to increase production and gain access to healthier food; the resulting availability of produce for sale brought increased income and improved living conditions, along with improved soil quality, outcomes the report attributes in part to the organizational capacity of the women involved in the association.

In two peripheral neighborhoods of Santa Rosa, La Pampa province, Argentina — Zona Norte and Villa Germinal — a 2014 ethnobotanical and agroecological study examined home gardeners' knowledge, uses and meanings attached to arvenses, spontaneous plant species growing alongside cultivated crops. Using ethnobotanical data-collection tools, researchers collected and identified 57 species; roughly half of informants said they remove these plants without using them, while the rest use them mainly as fertilizer for their gardens or feed for domestic animals. Published literature cited medicinal preparation as the most frequent use, and Cynodon dactylon ("gramilla"), the species appearing most often in the gardens, was also regarded by informants as a "pest."

At Worcester Polytechnic Institute (WPI) in the United States, the Floragenesis project proposed a campus community garden using food waste otherwise neglected from the dining halls to address concerns about freshness and localness. Over time, the composting component was intended to phase out the practice of exporting food waste from the main dining halls. The project focused on construction, productivity, and community garden management, drawing on prior WPI-specific composting feasibility studies. It won Judge's Winner at a 2014 poster presentation.

In Lubumbashi, Democratic Republic of the Congo, researchers analyzed the fertilizing value of different types of biowaste used in urban market gardening through principal component analysis of grower profiles, chi-square analysis of practices, and physico-chemical analysis of the waste materials. Most market gardeners were married women over 18 without land title; half the biowaste used was purchased chicken manure (with some pig manure), applied raw and buried in the soil, and while 33% of growers expected spreading it to increase productivity and improve soil physico-chemical properties, 48.3% expected it to improve vegetable growth appearance and boost yield.

This study evaluated vegetable and herb production across three growing systems—a green roof, raised green roof platforms, and in-ground—over three seasons (2009–2011). Tomatoes, green beans, cucumbers, peppers, basil, and chives were cultivated. All plants except pepper survived and produced biomass in all systems, yielding crops for analysis in 2009 and 2010. Yields and basil biomass were higher in-ground in 2009, while roof and platform systems showed similar results. The study suggests that vegetable and herb production is possible and productive in extensive green roof systems with proper management.

A pot experiment in India investigated the effect of Glomus mosseae on Trigonella foenum-graceum grown in arsenic-contaminated soil. Plants in arsenic-contaminated soil without mycorrhizal inoculum showed very poor growth performance across all aspects. However, when mycorrhizal inoculum was added to contaminated soil, plant performance improved, with the best results observed in non-contaminated soil with mycorrhizal inoculum.

This paper explores sustainable financing for urban agriculture, particularly as part of the sanitation value chain. Financing is considered from two perspectives: an adequate mix of public, private, and local finance to avoid external funding dependency, and the purpose of investment focusing on value chains in the sanitation and (peri)urban agricultural sectors. The emphasis is on exploring financing options for urban agriculture through the valorization of urban waste, aiming for clear beneficial impacts on the urban and peri-urban agricultural sector.

This paper aimed to assert that urban agriculture provides economic and environmental benefits to cities, specifically identifying ways the City of Atlanta could leverage these benefits. It tested the hypothesis that Atlanta can economically benefit by establishing urban agriculture as a land use, using a literature review, scaling data from other cities to Atlanta, and land suitability analysis. The analysis indicated that urban agriculture offers advantages in waste management, public land management, and stormwater management, demonstrating it as an economically viable movement providing social, environmental, and economic benefits.

In the Caribbean, kitchen gardens are categorized into home gardens and food forests, both grown on home plots. Home gardens are small areas for short-term crops, used for home consumption and sharing, while food forests are low-maintenance agroforestry systems with diverse plant species, including fruit trees and non-food hardwoods. These systems mimic a forest's vertical structure.

The green sisters movement involves Catholic nuns dedicated to environmental education and sustainability, exemplified by Homecoming Farm, an organic farm created in 1992 by the Sisters of Saint Dominic. The story is presented through a five-part news series, based on six visits and interviews with eleven individuals at Homecoming Farm in the summer and fall of 2012.

S Kelkar Tushar, A. Satish · · India (Mumbai)

The incidence of Arbuscular Mycorrhizal Fungi (AMF) in urban farming was investigated in Mumbai and its suburbs, India, specifically in wasteland near Central Railway side tracks. Roots of commonly cultivated crops like bhindi, chavali, and fenugreek, along with rhizospheric soil samples, were collected and screened for AMF colonization percentage and spore density. In these disturbed habitats, characterized by poor quality soil and irrigation from gutters and wastewater, incidences of mycorrhizal fungi were found to be higher in terms of percent colonization.

The Ecovillage 'Sanneoul' in Seocheon-gun, South Korea, was developed for urban dwellers returning to rural areas and to prevent rural population decline. The village incorporates ecological elements such as rainwater recycling, rooftop gardens, and ecological sewage disposal plants, and residents utilize sunlight and solar heat systems, garbage recycling, and pellet boilers. While residents are content with the village's ecological elements, significant dissimilarities among residents in age, profession, and previous living environments pose an obstacle to community maintenance.

Maxine J. Levin · Soil Horizons · United States

This commentary highlights a growing demand for soil information for green economy initiatives and climate change adaptation over the last 25 years. Despite this, USDA's funding and technical support for soil surveys in urban and nonfarm areas have been inconsistent and, in some places, nonexistent. The author argues for the vital role of modern soil surveys in addressing current needs.

Organic foods, initially championed in the early 20th century, gained commercial significance in the 1990s as consumers sought to avoid chemical residues and improve nutrition. However, scientific support for nutritional benefits and significant reductions in pesticide residue risks is weak. While organic crops reduce chemical runoff, they require more land due to lower yields, leading to the promotion of "local" foods and urban agriculture.
