Si l’agriculture urbaine est une notion de plus en plus évoquée par les institutions, les entreprises, les associations, les collectivités, les citoyens, les politiques, c’est qu’elle a certainement l’audace de vouloir créer une intelligence commune entre l’aména¬gement urbain et l’activité agricole et jardinière. Autrement dit, il s’agit d’offrir des solutions concrètes pour rendre nos villes plus durables et vivables. Dans une autre mesure, l’agri¬culture urbaine s’apparente à une des solutions possibles pour préparer les villes au changement climatique et tendre vers des systèmes alimentaires locaux.

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertilizers, were considered. The activities of soil enzymes including dehydrogenase, ?-glucosidase, arylsulfatase, urease, alkaline and acid phosphatases were used as indicators of important microbial mediated functions and the soil chemical properties were measured in the soils applied with organic or inorganic fertilizer for 10 years. Fatty acid methyl ester analysis was applied to determine the soil microbial community composition.

Improving Health And Income With The Assistance Of Agricultural Extension
By Robert L. Freedman, Tucson, Arizona.
International Journal of Agricultural Extension
The wide spread presence of home gardens in developing nations is a strong foundation for food security, both in terms of quantity and quality. Indigenous wild food plants are a rich source of health-giving micronutrients, which are missing from highly refined fast/convenience foods the growing reliance on which has caused an ever-increasing occurrence of dietary-related diseases.

Call for papers: “Assessing the Sustainability of Urban Agriculture: Methodological Advances and Case Studies”
For the special issue of the MDPI journal Sustainability
Dr. Esther Sanyé-Mengual
This Special Issue calls for papers that contribute to the assessment of the sustainability of urban agriculture, both by advancing methodological approaches and by providing results from case studies. Cities have been identified as an essential element in addressing global concerns, particularly due to the growing population, and food flow is key in the urban metabolism and in the design of future sustainable cities. Resulting from the environmental awareness of the globalized food system and urban social and economic gaps, urban agriculture has grown in recent years aiming at increasing food security while coping with climate change.

« Ilots de verdure » situés généralement en milieu urbain ou périurbain, les jardins associatifs sont des espaces sur lesquels des individus membres d’un groupe associatif pratiquent le jardinage. On y cultive principalement des légumes, fruits, condiments et fleurs, mais aussi des éléments qui vont bien au-delà des plantes cultivées, comme les liens sociaux, les loisirs, l’éducation à l’environnement, la citoyenneté etc. Gérés par des associations, ces espaces peuvent être sous forme de parcelles collectives ou bien délimités en plusieurs lopins de terre individualisés, et ce, pour la grande joie des personnes qui y ont accès.

Urban Agriculture & Regional Food Systems, formerly published by Baltzer Science Publishers, recently joined the ACSESS portfolio of agricultural and environmental journals.
The Journal is supported by RUAF.
Urban Agriculture & Regional Food Systems is a multi-disciplinary, peer-reviewed and open access journal focusing on urban and peri-urban agriculture and systems of urban and regional food provisioning in developing, transition, and advanced economies.
The journal intends to be a platform for cutting edge research on urban and peri-urban agricultural production for food and non-food (e.g. flowers, medicine, cosmetics) uses and for social, environmental and health services (e.g. tourism, water storage, care, education, waste recycling, urban greening). It aims to explore, analyse and critically reflect upon urban and regional food production, processing, transport, trade, marketing and consumption and the social, economic, environmental, health and spatial contexts, relations and impacts of these food provisioning activities.

Agricultural chemicals are only part of the problem. Homeowners and urban landscapes are big contributors, even when hives are directly adjacent to crop fields.”

“Although crop pollen was only a minor part of what they collected, bees in our study were exposed to a far wider range of chemicals than we expected,” said Krupke. “The sheer numbers of pesticides we found in pollen samples were astonishing. Agricultural chemicals are only part of the problem. Homeowners and urban landscapes are big contributors, even when hives are directly adjacent to crop fields.”
Long, now an assistant professor of entomology at The Ohio State University, said she was also “surprised and concerned” by the diversity of pesticides found in pollen.

Report: Community and home gardens increase vegetable intake and food security of residents in San Jose, California
The La Mesa Verde program in San Jose helps low-income families to establish their own vegetable gardens. A pilot study found that gardening in either a community or backyard space made a significant contribution to gardeners’ daily vegetable intake.
“Gardening made a substantial contribution to vegetable intake regardless of socioeconomic background or previous gardening experience,” said co-author Lucy Diekmann, a postdoctoral researcher in the Food and Agribusiness Institute at Santa Clara University.

As of 2013, 42 million American households were involved in growing their own food either at home or in a community garden plot. The purpose of this pilot study was to document the extent to which gardeners, particularly less affluent ones, increase their vegetable intake when eating from either home or community garden spaces. Eighty-five community gardeners and 50 home gardeners from San Jose, California, completed a survey providing information on demographic background, self-rated health, vegetable intake and the benefits of gardening.

Sudan: Urban Agriculture Facing Land Pressure in Greater Khartoum – The Case of New Real Estate Projects in Tuti and Abu Se ‘id
Dr Alice Franck’s Presentation On Urban Agriculture At The Sudanese Institute Of Architects (SIA)’S 4Th Scientific And Professional Conference
On 23rd May, 2016, Dr Alice Franck, Geographer and Coordinator of CEDEJ Khartoum, presented her paper at the Sudanese Institute of Architects (SIA)’s 4th Scientific and Professional conference.
Excerpt from Abstract:
My initial research into this location of intense speculation examined the future of the central areas that remained under agricultural activity and how they were gradually being transformed into urban areas (Franck 2007). The approach adopted analysed the resistance of agriculture and farmers to the spread of real estate and the pressure of competition over land ownership. Five years later, the action in favour of urban plan renewal has been drastically intensified and the capacity for resistance severely diminished; three of the five market gardening areas (Tuti, Shambat, Abu Se’id, Abu Rof and Mogran) observed during fieldwork in 2001–5 are subject to huge real estate projects (Mogran, Abu Se’id and Tuti). In this chapter, I focus my analysis on how landowners and the entire agricultural sector can both adapt to and confront the transformation.

A local lady and scholar, Dr Hangwelani Hope Magidimisha, made history when she became the first black woman to get a PhD in Urban Planning at the University of Kwazulu Natal.
Her Masters Thesis: The responsiveness of town planning to urban agriculture in low-income neighbourhoods : a case study of Kwa-Mashu in Durban, South Africa.
Excerpt about her academic journey:
A resident of the rural Ngudza village, Magidimisha stated that her motivation to study and work hard came from her uneducated parents. “I am from a humble beginning with supportive parents and a supportive community,” she said. “When I was in Grade 12 at Ramugondo Secondary, our school achieved a 100% pass rate for the first time in history. We were a highly motivated class. This was also the motivation for me; it just proved to me that the sky is the limit.”
She indicated that hard work had always had a way of paying off. “If I work hard, anything is possible,” she beamed. “I like doing what people think is impossible. I guess this is something I got from my father.”

Given the search for new solutions to better prepare cities for the future, in recent years, urban agriculture (UA) has gained in relevance. Within the context of UA, innovative organizational and technical approaches are generated and tested. They can be understood as novelties that begin a potential innovation process. This empirical study is based on 17 qualitative interviews in the U.S. (NYC; Philadelphia, PA, USA; Chicago, IL, USA). The aim was to identify: (i) the most relevant areas of learning and innovation; (ii) the drivers of innovation; (iii) the applied novelties and their specific approach to overcoming the perceived obstacles;

Farmland mapping project indicates more than 90 percent of U.S. could eat food grown or raised within 100 miles of their homes
A project by UC Merced Professor Elliott Campbell mapped the potential of every American city to obtain food locally. Research shows unexpectedly large current potential for productive farmland.

Campbell and his students looked at the farms within a local radius of every American city, then estimated how many calories those farms could produce. By comparing the potential calorie production to the population of each city, the researchers found the percentage of the population that could be supported entirely by food grown locally.
The researchers found surprising potential in major coastal cities. For example, New York City could feed only 5 percent of its population within 50 miles but as much as 30 percent within 100 miles. The greater Los Angeles area could feed as much as 50 percent within 100 miles.

The study, published in the British Food Journal, shows that three of the four top reasons farmers grow in urban areas – food security, education, community building, and producing food for the market – have social motivations.
New York University
They analyzed data collected from a national survey of 370 urban farmers. Thirty-five questions, covering the 2012 farm year, addressed food production and marketing practices, risks and challenges, information and technical assistance needs, farm size and location, age of primary farmer, and farm characteristics.
The researchers found that food production is an essential part of the mission for all urban farms, but approximately two thirds of farmers surveyed also expressed a social mission. These social missions are primarily related to food security, education, and community building.
