Pre-Implementation Perceptions Among Teachers on the Use of Ecological Sanitation and Application of Human Urine as Fertilizer
2020Govinda Prasad Devkota, Sheri Lee Bastien, Petter D. Jenssen, Manoj K. Pandey, Bhimsen Devkota, Shyam Krishna Maharjan · International Education Studies · Nepal
This Participatory Action Research study in Nepal investigated five teachers' perceptions of using urine diversion dry toilets (UDDTs) and human urine as fertilizer in school gardens. Few teachers accepted human urine as fertilizer, considering it impure and expressing unwillingness to use it on crops. Teachers disliked UDDTs due to perceived bad odor and uncomfortable sitting positions, especially for females, and felt urine as fertilizer was unnecessary.

2020Olivia Lee · Johns Hopkins University eBooks · United States (Chicago)
This study, drawing on affect theory, examines community gardens in Chicago's low-income, primarily Black South Side neighborhoods. It argues that while these gardens offer a spatial break from violence, they appear unable to fully counteract the ongoing marginalization by race and socioeconomic status. The gardens represent a quiet, nascent resistance against neoliberal injustices through intimate human-nature interaction.

2020Joycelyn K. Quansah, Cesar L. Escalante, Angela Parry‐Hanson Kunadu, Firibu Kwesi Saalia, Jinru Chen · Agriculture · Ghana (Accra)
A survey was conducted among 102 urban leafy green vegetable farmers from 12 farming areas in Accra, Ghana, to determine agricultural practices and their association with microbial safety of vegetables produced. It was observed that 70% of farmers used water from waste drains for irrigation, 99% used incompletely composted manure, 96% harvested with bare hands, and over 60% disagreed that polluted irrigation water can contaminate vegetables or make consumers sick. Vegetables cultivated by farmers with no formal education, less food safety knowledge, and those who disagreed about contaminated water causing illness were associated with higher fecal coliform and Enterococcus sp. counts.

2020Sam Ramsden · Voluntary Sector Review · United Kingdom
This article explored an externally funded charity-led project in a deprived area of the UK, implementing urban agriculture, community gardening, and household energy activities. The project successfully engaged marginalized people, who strongly voiced outcomes including reduced isolation, improved mental health, and increased resilience and self-reliance. Environmental outcomes were less tangible but included improvements to the local environment and reduced energy usage. However, after the funding finished, marginalized participants were vulnerable to outcomes not being sustained in the long term.

2020Salvatore Engel‐Di Mauro · Journal of Environmental Quality · Global
This review examines atmospheric sources of trace element (TE) contamination in cultivated urban areas (CUAs), noting that these sources are understudied and poorly understood despite extensive research on TE contamination in CUAs. Existing research often assesses atmospheric deposition indirectly or lacks controls for other TE contaminants, and shows little engagement with atmospheric sciences methodological guidelines, which reduces confidence in current findings. The review suggests combining atmospheric science techniques with existing robust methodologies for TE contamination studies in CUAs.
