2024Bernard Afiik Akanpabadai Akanbang, Millicent Awialie Akaateba, Prosper Issahaku Korah · Discover Cities · Ghana (Wa)
This exploratory cross-sectional survey in seven rapidly growing neighborhoods in Wa, Ghana, administered 285 questionnaires to residents to understand motivations, challenges, and constraints of home gardening. Results showed 56% of respondents had gardens, primarily motivated by beautification (56.1%) and food production (52.3%). Limited space (49%) and busy schedules (34%) were identified as main barriers. The study found that while garden ownership aligned with the autonomy need, the relationship need, which correlates with environmental motivations, was notably low among residents. This indicates a limited effect of environmental awareness on home gardening motivation in the surveyed population.

2023Radenka Kolarov, Mirjana Ljubojević, JOVANA SUCUR ELEZ, Mirjana Adakalić, BILJANA LAZOVIC, Dejan Prvulović, Sezai Erċışlı, DJORDJE MALENCIC · TURKISH JOURNAL OF AGRICULTURE AND FORESTRY · Serbia
This study compared bioactive compounds in pomegranate genotypes from a continental region (Sremski Karlovci, Serbia) and a Mediterranean urban region (Bar, Montenegro). Analysis of phenolics, tannins, flavonoids, proanthocyanidins, pigments, vitamin C, acidity, pH, and sugars, along with DPPH and ABTS antioxidant tests, revealed that pomegranates grown in the continental area had significantly higher amounts of biochemically active compounds than those from the Mediterranean urban region. This suggests adaptation to continental conditions, with continental samples showing greater antioxidant potential and proanthocyanidins content.

2022Ada Górna · Prace i Studia Geograficzne · Global
A study analyzed urban agriculture supply chains in Havana, Kigali, Bissau, and Singapore based on fieldwork conducted from 2018 to 2020. It found that while shortened supply chains are typical for urban agriculture, their benefits are not arbitrary and depend on local economic, social, and spatial conditions, as well as the supply chain's organization and structure. The positive effects of localized food production are not universal, indicating a need for further research into supply and value chain structures.

2020Catalina Cruz-Piedrahita, Caroline Howe, Audrey de Nazelle · Global Transitions · Global
This scoping review analyzed 138 papers to develop a conceptual framework on the impacts of urban horticulture (UH) on public health in the Global North. While UH is proposed as a tool for health improvement, the review notes a lack of systematic information on its benefits, barriers, costs, and risks in these regions. The framework visualizes relationships between UH and public health, providing evidence for both positive and negative connections regarding mental health, physical activity, diet, and socialization.

2019Navin Ramankutty, Vincent Ricciardi, Zia Mehrabi, Verena Seufert · Agricultural Economics · Global
A review was conducted on the production, environmental, and socioeconomic performance of three alternative farming systems: organic, smallholder, and urban agriculture. Organic agriculture offers environmental, livelihood, health, and nutritional benefits but is hampered by lower yields and higher prices. Smaller farms exhibit higher yields and biodiversity but result in lower incomes for farmers. Urban agriculture can alleviate pressure on rural landscapes, provide nutritional benefits to the urban poor, and engage urban dwellers in food system challenges, but it cannot scale up to be a substantial solution on its own.

2019Héctor Ávila Sánchez · Investigaciones Geográficas Boletín del Instituto de Geografía · Global
This study analyzed the impact and potential of Urban and Peri-urban Agriculture (UPA) on urban food systems, focusing on cities in Western Europe, North America, and Latin America. It concluded that while UPA practices have increased, their presence in urban food systems remains limited, and their consideration in territorial public policies is still marginal. In developed countries, its impact has been primarily therapeutic, landscape-related, and for heritage preservation, while in poorer countries, it has contributed to self-sufficiency for low-income urban populations, public space recovery, social fabric strengthening, and community development.

2019Julian Cribb · Cambridge University Press eBooks · Global
This paper points out that none of the world's megacities can feed themselves, and food chain risks pose an imminent threat of starvation. It presents concepts such as climate-proof food supplies, novel urban food production systems, the importance of urban permaculture, rewilding, and developing wise consumers as solutions to urban food risk. However, it does not explicitly state that these solutions fully resolve the issue of urban food self-sufficiency.

2016Cécile Faliès · Problèmes d Amérique latine · Chile (Santiago)
This article provides an overview of agriculture around Santiago, Chile, based on fieldwork conducted since 2005. Despite the presence of agriculture linked to Santiago and Valparaiso, and the emergence of some forms like organic farming, it is difficult to classify this as urban agriculture due to the peripheral location and limited number of plots. The study indicates that urban agriculture, as commonly defined, has a limited presence in the Santiago metropolitan area.

2016Jin-Hee Ju, Won-Tae Kim, Hui Xu, Young-Han Yoon, Eun‐Young Choi · Journal of Environmental Science International · Global
This study investigated the influence of hydrophilic polymer (HP) mixture ratio on the growth of eggplant (Solanum melongena) for lower maintenance urban agriculture via green roofs. As the hydrophilic polymer mixture ratio increased, the growth index, number of leaves, leaf length, leaf width, and dry weight of shoot and root decreased. Specifically, these values were significantly lower in HP5.0% and HP10.0% treatments compared to the control, and the survival rate was lowest at 56% in the HP10.0% treatment.

2010Eva Collins, Kate Kearins · Academy of Management Learning and Education · New Zealand (Auckland)
A sustainability instructor took a graduate class to an eco-village near Auckland, New Zealand, where students observed off-grid homes and community gardens. While New Zealand students were inspired by the alternative lifestyle, two international students from China and Tajikistan expressed that this lifestyle was how they lived at home and they did not wish to live that way, preferring the New Zealand lifestyle. This indicates a limited appeal of the eco-village model to some international students.

2002Maurizio Tiepolo · PORTO Publications Open Repository TOrino (Politecnico di Torino) · Niger
This paper investigates whether urbanization in Niamey, Niger, generates or aggravates urban food insecurity by examining agro-pastoral production, food demand, and buying power. It found that Niamey's high rate of urban growth has increased food insecurity for its inhabitants. This insecurity is attributed to low productivity of peri-urban agriculture, insufficient food influxes, rising prices, extreme poverty, and a nutrient-poor diet, with current measures failing to address root causes like land tenure uncertainty.

2000Simon Clarke, Elena Varshavskaya, Сергей Алашеев, Marina Karelina · Work Employment and Society · Russia
This paper examines the "myth of the urban peasant" in Russia, which suggests urban households survive economic collapse through subsistence agriculture. Based on official and survey data analysis, it shows that while many urban households grow food, those with low incomes are least likely to do so, and subsistence production complements rather than replaces paid employment. Furthermore, those who grow their own food work long hours for little return, spending no less on purchased food than those who grow nothing.
