Governance failurePolicyCommunityEconomicsCollaborative planning via urban agriculture: The case of Tegucigalpa, Honduras
2017Andrea Oyuela, Arnold van der Valk · Agroecology and Sustainable Food Systems · Honduras (Tegucigalpa)
This study questions the adequacy of Tegucigalpa's top-down planning system in Honduras and explores urban agriculture (UA) as a potential building block for a bottom-up strategy. While UA is organized in Tegucigalpa due to residents' need to overcome food insecurity and hardship, the concept of active citizenship and bottom-up development is not yet consolidated. Furthermore, challenges exist regarding the resources needed for practicing UA and the diffusion of knowledge to the population.

2017Volker Häring, Delphine Manka’abusi, Edmund Kyei Akoto-Danso, Steffen Werner, Kofi Atiah, Christoph Steiner, Désiré Jean‐Pascal Lompo, S.G.K. Adiku, Andreas Buerkert, Bernd Marschner · Scientific Reports · Sub-Saharan Africa
This 2-year study in Tamale (Ghana) and Ouagadougou (Burkina Faso) investigated the effects of biochar, wastewater irrigation, and fertilization on sandy, nutrient-depleted soils in urban vegetable production. Biochar addition (2 kg m⁻²) initially doubled soil organic carbon (SOC) stocks, but 35% SOC losses occurred afterward. Both biochar types had no effect on soil pH, phosphorus availability, or cation exchange capacity, though rice husk biochar retained nitrogen. The study found that the effects of biochar and waste water were less pronounced than reported elsewhere.

2017Devon A. Mihesuah · American Indian Culture and Research Journal · United States
In Oklahoma, tribes have initiated numerous food projects over the past three decades aimed at achieving food sovereignty. However, Oklahoma's complex history, environmental issues, and current politics present challenges such as uneven food quality, poor indigenous health, intratribal factionalism, racism, and a stark dichotomy of affluence and extreme poverty. These factors complicate the creation of self-sufficient food systems and the reconnection of tribal members with traditional foodways.

2017Donovon Ceaser · Ethnography & Education · Global
This study analyzed the leadership of founder John Browne at Green Shoots, a nonprofit service-learning urban farming school established in 2010, using the theory of founder's syndrome. Browne, despite an openly egalitarian community of practice ethic, created a hierarchy at the school that led to a staff walk-out and subsequent firings. Findings revealed Browne as a charming and inspirational teacher who engaged in dominating leadership contradicting the community of practice's ideals, resulting in disrespected students, disillusioned staff, and a founder unable to take responsibility for his leadership.

2017肇 石原, Hajime ISHIHARA · Institutional Repositories DataBase (IRDB) · Japan
Since 1990, the weakening of agricultural management foundations has been observed in urban areas of Nara Prefecture, though the decrease in productive green space and the number of full-time farmers remained at a certain level. Rice cultivation was the main crop in many areas, and engagement in agriculture-related businesses, apart from direct sales, was not extensive. Regarding the designation of productive green spaces, many cities were reluctant during the initial designation following the revised Productive Green Space Act and also during the Heisei mergers, which is identified as a challenge for future land use planning.

2017Elena Domene Gómez, Francesc Coll, Marta Garcia-Sierra · Dialnet (Universidad de la Rioja) · Spain (Barcelona)
Informal vegetable gardens have proliferated in Barcelona's urban periphery since the 1980s, serving as leisure spaces and food sources, and are a relevant form of agriculture. However, these "unregulated" spaces are not considered in urban and peri-urban agriculture promotion policies. A GIS methodology mapped these gardens in the Barcelona metropolitan area for 2009 and 2015, showing an increase in occupied surface during the recent economic crisis. The study evaluates contradictions leading municipal managers to eliminate or regulate these informal spaces, attributing them partly to the subjectivity of the urban and peri-urban agriculture concept and its supposed multifunctionality.

2017Abdul Rahman Conteh, Alusaine Edward Samura, E. L. S. Hinckley, Osman Nabay, Mohamed S. Kamara · Journal of Agricultural Science and Practice · Sierra Leone (Freetown)
This study was conducted to identify the risks of heavy metal contamination in urban and peri-urban cropping systems in Sierra Leone. Soil and plant samples were collected from 72 sites in Freetown and Bo and analyzed for Zn, Cu, Cr, Ni, Pb, and Cd. Heavy metals were detected across all sites, and some mild risk of cadmium toxicity was observed in densely populated areas of Freetown, though this was not reflected in plant uptake of cadmium.

2017Seyedardalan Ashrafzadeh, Niklas J. Lehto, Gareth Oddy, Ron G. McLaren, Ling‐Fen Kang, Nicholas Dickinson, Johannes Welsch, Brett Robinson · Applied Geochemistry · New Zealand (Christchurch)
A study in Christchurch, New Zealand, measured heavy metal (HM) concentrations in suburban garden soils and soils at risk of HM contamination due to former land uses or nearby activities. HM concentrations in suburban garden soils were higher than normal background levels, with 46% of urban garden samples exceeding the residential land use national standard for lead (210 mg kg−1), and the most contaminated soil reaching 2615 mg kg−1. Arsenic and zinc also exceeded national standards in 20% of soils. These findings suggest that soil HM concentrations should be key criteria when determining future land use for former residential areas demolished due to the 2010 and 2011 earthquakes, and that redeveloping these areas as parklands or forests would result in less human HM exposure than agriculture or community gardens where food is produced and bare soil is exposed.

2017Nerea Morán Alonso, Ícaro Obeso Muñiz, Agustín Hernández Aja, Felipe Fernández García · Moravian Geographical Reports · Spain
This paper analyzed the evolution of peri-urban agriculture in Spain's Madrid and Oviedo metropolitan areas to identify revitalization opportunities. Using aerial images and cartographic bases, the study found that peri-urban agriculture has suffered from urban occupation and internal changes in crops and agricultural uses, experiencing a process of decline. Innovative initiatives are explored as potential revitalization opportunities.

2017Dorothy Menefee, Ganga M. Hettiarachchi · · United States
Soil contamination with potentially toxic trace elements and anthropogenic organic pollutants is a widespread problem in urban areas worldwide. While urban agriculture increases food security, potential risks exist without knowledge of urban soil contamination. Lead (Pb) contamination is a widespread and common urban soil issue associated with human health risks, with almost half of US EPA Superfund sites having Pb contamination. Cadmium (Cd) is also a widespread urban soil pollutant, largely from industrial activities like plastic manufacturing, battery disposal, and metal ore processing. The bioavailability of soil Pb to humans is unusually low and generally tied to Pb speciation.

In New York City, chapter six revealed how civic and public actors working outside PlaNYC iteratively embedded urban agriculture and food policy into municipal planning efforts. Within the void created by city hall’s lack of engagement, other figures in the municipal government seized the opportunity to advance food policy agendas for New York City. The 2011 update to PlaNYC included a brief crosscutting section on food, although it lacked capital funding to fuel the achievement of its stated goals, and was seen by advocates as a symbolic and political achievement.

2017Gabin Korbéogo · Environment and Urbanization · Burkina Faso (Ouagadougou)
This article explores how land tenure, water flows, and water quality are legally, politically, and socially framed in urban agriculture in Ouagadougou, Burkina Faso. Urban agriculture serves as a revenue source and a socio-political arena involving state representatives, experts, and farmers. Public authorities monitor legal standards for water use and hygiene, while farmers strive for efficient resource use, sometimes challenging official norms. These competing interests lead to conflicts over resource use or rule legitimacy, which are negotiated through institutional or informal bargaining.

2017Georgia Pollard, Philip Roetman, James Ward · Kobra (Universitätsbibliothek Kassel) · Australia (South Australia)
While urban agriculture is seen as a sustainable approach to improving food security, there is a significant knowledge gap regarding the financial accessibility of urban food production for all households. If urban agriculture remains primarily a middle-class discretionary activity, its role in city-wide food security improvement will be limited. This paper demonstrates that citizen science offers an effective approach to investigate the inputs (labor, costs, water use) and outputs (produce yields, value) of urban food gardens, using the Edible Gardens project in South Australia as an example.

This study aimed to determine the concentration of potentially toxic elements (Cd, Cr, Cu, Fe, Ni, Pb, Zn) in berries grown in allotment gardens in Rīga city, Latvia. Samples of raspberries, strawberries, red currants, black currants, gooseberries, and cherries were analyzed using atomic absorption spectroscopy. The results showed significant variability of element concentration among the berry species, with mean concentrations for Ni at 0.54 mg/kg, Pb at 0.20 mg/kg, Cr at 0.10 mg/kg, and Cd at 0.03 mg/kg.
Contamination & food safetyHealthA systemic methodology to characterize peri-urban agriculture for a better integration of agricultural stakes in urban planning
2017Esther Sanz Sanz, Claude Napoléone, Bernard Hubert, Aruna Popuri · · Global
Existing urban planning documents inadequately consider the specificities of peri-urban agriculture as an economic activity requiring arrangements not always adapted to an urban vision of agricultural spaces. This paper proposes a systemic methodology to characterize peri-urban agricultural spatial units, aiming to provide an inventory of peri-urban agricultural areas tailored to urban planning practitioners' constraints. The approach seeks to focus public action on areas where it is most likely to be efficient within a territorial project.

2017Bethany B. Cutts, Jonathan London, Shaina Meiners, Kirsten Schwarz, Mary L. Cadenasso · Local Environment · Global
This paper applies a dynamic spatial politics framework to interpret a 30-year conflict over an urban garden in Sacramento, California. It examines how urban gardens, often idealized, are also sites of conflict due to competing visions of "soil" versus "dirt." The study highlights that contaminants like lead in the soil contribute to this instability, reframing fertile soil as dangerous dirt, and influencing the garden's transformation from a countercultural space to a gentrified amenity.

An ethnographic study in Tamale, Northern Ghana, assessed the sustainability of urban vegetable production between 2008 and 2014. While urbanization increased cultivation of profitable vegetables like cabbage, the practice involved irrigation with grey and wastewater and high pesticide use, posing health and environmental hazards. Industrial growth reduced open space urban agriculture by 8.7%, leading farmers to use interstitial spaces and peri-urban fringes, indicating a dynamic but not yet sustainable production system.
