Contaminated vegetables grown and consumed in cities of the global South have adverse public health consequences. Through interviews with farmers, traders, consumers and institutional representatives, this article explores why stakeholders in the irrigated vegetable value chain in Accra continue unsafe practices. The multi-stakeholder data are analysed by combining a behavioural model with a framework of complex stakeholder interactions. Arguably, a systemic approach would help meet stakeholders' opportunity, capability and motivation needs and actualise current efforts to promote safe practices. Findings indicate the need for all stakeholders to develop a shared understanding of each other's practices and co-design flexible arrangements that better integrate their diverse rationales, knowledge and constraints. Improving hygiene and food safety from farm to fork requires political commitment that accounts for land tenure insecurity and the high cost of safe water.

This paper catalyses the academic urgency to understand agri-food system transformation pathways. Such transformation requires new food growing imaginaries of rooted in a change of thinking and ways of engaging with more-than-human perspectives. Urban spaces are hubs of human and more-than-human interactions, and urban organic farming offers an excellent site for exploring such new food growing imaginaries. The research presented here innovates theoretical and methodological knowledge in more-than-human geography. It develops alternative food growing imaginaries through a sensory ethnography at an urban organic workers’ cooperative Organiclea and visual arts methodologies. Through that, the paper brings to the fore the marginalized more-than-human perspectives by exploring more-than-human sensory Umwelts – taste and nutrition for the soil, sound for soil denizens, smell for honeybees, tactile perception for common weeds – and understanding human experience of food growing through sight. Attuning to a more-than-human sensorium broadens our knowledge of the life stories of other biotic and abiotic critters and recognizes that human and more-than-human world-making projects are interconnected. The paper concludes that sensory engagement is critical to the development of new imaginaries for a more sustainable food production. [ABSTRACT FROM AUTHOR]

Agricultural activity, as practised in the lowlands of the city of Yaoundé, gives rise to many concerns about the site of operation and the dubious quality of the water used. This work has the aim to assess the possibilities of using effluent from a wastewater treatment plant for hydroponic cultivation of lettuce ( Lactuca sativa L. ;) in urban agriculture. The experimental set-up was a completely randomised block design with three replications. The treatments applied to the lettuces were: raw effluent (T1), effluent diluted to 50% (T2) and 75% (T3), a solution of chemical fertilizer (T4) Maxigro 10-5-14 at a dose of 100 g for 50 l of tap water considered as a positive control and tap water considered as a negative control (T5). The growth parameters (plant height, number of leaves and leaf area) of the lettuces were evaluated along with their chlorophyll, fibre and protein content. The results show that T3 and T4 significantly improved (P<0.05) the growth parameters (18.96 cm and 16.37 cm for plant height, 9.87 and 11.65 for leaf length, 7.41 and 7.49 for number of leaves, 68.33 cm2 and 47.51 cm2 for leaf area, respectively). T3 and T4 showed the greatest improvement in chlorophyll a, protein and fibre content, with 36.54 and 25.90 ppm for chlorophyll a, 26.85 and 26.21% for protein and 1.53 and 1.34% for fibre, respectively. T3 obtained the best physiological and organo-mineral parameters after T4. The results obtained show that treated wastewater and hydroponics have significant potential that could be of interest to farmers. [ABSTRACT FROM AUTHOR]

L’agriculture maraîchère en ville contribue à l’alimentation de la population, lui offre du travail et lui procure un revenu non négligeable. L’Oignon (Allium cepa) est l’épice le plus utilisé dans les mets de ménages de Kikwit et ses environs à cause de ses vertus. Il est consommé cru ou préparé et utilisé en indigenothérapie pour guérir certaines maladies. Cependant, cette épice est confrontée à d’énormes problèmes : faible production, commercialisation, utilisation abusive des engrais chimiques et le manque de connaissances agricoles sur la culture chez les maraichers. Ensuite, elle n’est pas cultivée là où sa demande est la plus forte. Dans ce texte, les auteurs tentent, avec la méthode de «Champs Ecole Paysans », de montrer et d’encourager les ménages qu’il est possible de produire dans son jardin l’oignon avec ou sans apport de matières organiques.

Cette étude applique l’approche des systèmes agri-urbains pour faire état d’une dynamique d’une forme d’agriculture urbaine, en prenant le cas des jardins partagés d’autoproduction (JPA) de la ville de Québec au Canada. L’analyse repose sur des entrevues et une revue de littérature grise, aboutissant à une typologie des JPA basée sur quatre dimensions spécifiques et une cartographie des sites. Deux périodes clés émergent dans le développement des JPA à Québec : la première, des années 1970 à 2010, est caractérisée par l’émergence de l’agriculture urbaine et la prédominance des jardins communautaires en pleine terre. La deuxième période, dans les années 2010, est marquée par une forte croissance des JPA, en particulier des « aménagements comestibles » (aménagements paysagers à vocation comestible), et une reconnaissance accrue de la multifonctionnalité de l’agriculture urbaine. Les organismes communautaires et associatifs jouent un rôle central dans cette croissance et la dynamique générale des JPA.

Increasing urbanization generates new challenges for cities, including housing shortages, environmental degradation, public health concerns, and food security issues, just to mention a few. High levels of food insecurity can motivate planners to increase their support for community gardening forms of urban agriculture. The COVID‐19 pandemic has amplified many pressures of urban living. In this paper, we focus on challenges around urban agriculture activities, in particular, exploring regulatory approaches and limitations when it comes to growing food in cities. This study uses qualitative research methods to explore the main barriers to urban agriculture as perceived by community‐based groups in Victoria, British Columbia. Data collection included 18 semi‐structured, face‐to‐face interviews, and two community mapping workshops with local residents, government officials, and non‐governmental groups. Data analysis generated initial codes and themes that revealed "urban agriculture zones" and "garden‐style" apartment housing as important avenues for urban agriculture projects. These findings are relevant in Victoria, where more than half of the population lives in apartments. A food action plan is a regulatory mechanism that can boost food production when aligned with the official community plan. Any progress towards far‐reaching changes, however, requires an efficient urban agriculture development process, including creating site inventories, increasing stakeholder participation, reducing waitlists, and tackling high land prices. Key Messages: This paper investigates existing planning barriers to urban agriculture in cities.We argue that urban planners must focus on existing regulatory challenges related to zoning bylaws, land‐use policies, and governance strategies to enhance food‐growing opportunities.Changing the mechanisms for urban agriculture development approvals and creating a specific food action plan are key elements for implementing successful food‐growing urban projects in cities.

Cet article propose une réflexion collective sur l’engagement militant à partir de la recherche en agriculture urbaine en France et aux États-Unis. Il s’appuie sur une revue qualitative de la littérature, complétée par une série de séminaires. Ancrée dans la géographie critique et militante, la recherche sur l’agriculture urbaine aux États-Unis se concentre sur le jardinage communautaire et promeut la justice alimentaire. Dans le contexte français, les registres espaces et acteurs considérés sont beaucoup plus diversifiés et la réflexivité critique et politique comparativement moins développée. L’article se conclut par un appel à plus de réflexivité critique en ce domaine.

This article explores the contributions of a pragmatist approach to social innovation studies. It characterizes the epistemological assumptions of pragmatism and its implications to conceive of "science in action." It explores the contributions of pragmatisms in developing a perspective to analyze civil society and its action to promote social innovation, focusing on the key notions of "public inquiry" and "democratic experimentalism." The aim is to discuss the contributions, challenges, and limits of conducting pragmatic studies--from an analytical and methodological perspective--giving way to co-operative and engaged research that connects and co-ordinates teaching and knowledge transfer, theory and practice, experts and ordinary citizens, and knowledge and experiences in social innovation studies.

The issue of urban and peri-urban agriculture is topical in Tunisia today as it is becoming a concern for territorial policies and agri-urban strategies in terms of environment management and sustainability. Nevertheless, this multidisciplinary theme still shows imprecisions and tautologies in terminologies and acceptability of this hybrid agricultural and urban production field. It is in this context that this work is undertaken to identify the perception of urban and peri-urban agriculture based on the various visions of different actors, public, semi-public and private. Surveys conducted directly (face to face) with a representative population of 85 actors reveal a dualism characterized by both "distancing" and "non-distancing" in the different qualifications of urban and peri-urban agriculture. It appears that professionalization and visibility of this sector are both reduced. However, all the surveyed people converge in affirming the interest of urban and peri-urban agriculture, but in a vision supporting a productivity agriculture. For 58% of public actors, urban and peri-urban agriculture is useful, but in a vision of a residual agricultural production; 30% of public actors consider it as in transition of latency, stock, or even as a land reserve. Semi-public actors show an anchoring in the socio-spatial dimensions and this, in an environmentalist agricultural landscape logic. This qualification is identified among three quarters of semi-public actors, and 50% for public actors. Another qualification is expressed by private actors, who are rather green town planning enthusiasts, as more than two thirds of them favor agro-ecological mediation services, green trades and the procurement of quality and proximity agricultural products.

This article takes the form of a dialogue between a researcher (Marco Alberio, holder of the Canada Research Chair in Social Innovation and Territorial Development) and two practitioners (Ophélie Couspeyre, Development Officer, Table nationale des corporations de développement communautaire, and Érick Plourde, Executive Director, Corporation de développement communautaire de Lévis). Taking up several points that emerged during a joint event that took place in October 2020, this dialogue aims to discuss the practice of autonomous community action (especially through the voices of the protagonists themselves) in a social, economic and political context that is changing rapidly--and not just because of the pandemic.

Previous research has identified the potential of community-based development processes to reverse inequalities. However, in many cases, constraints arise that hinder the achievement of community goals. This article focuses on the role contributed by a school to overcome these barriers. Specifically, we address the role played by the Mare de Déu de Montserrat School, which is a Learning Community, in the launch and development of a community-based process. Known as The Dream, this process was initiated by a group of unemployed Moroccan residents in an impoverished urban neighbourhood in Spain. Through this process, the neighbours have created a self-managed community garden, which has enabled them to improve their job training and build social networks. Based on the communicative methodology, our qualitative study finds that this school has contributed to the creation of specific conditions that helped to overcome some barriers that had hindered the emergence of community responses. In addition, the contributions of the school have promoted a horizontal and dialogical organization of the process, placing neighbours in central positions in decision-making and leadership roles. This case study provides relevant theoretical and practical implications for the contributions that certain school-based interventions can provide to promote community initiatives in impoverished environments.

L’agriculture urbaine est en expansion dans de nombreuses villes du monde. Son analyse invite à dépasser les frontières séparant traditionnellement les études urbaines des études agricoles. Cet article souligne l’intérêt du concept de système agri-urbain pour penser la complexité des relations ville-agriculture. À partir de l’étude d’une ville d’Afrique de l’Ouest, son objectif est d’élaborer une grille de lecture de ces relations à l’échelle territoriale de la ville et de sa région. Trois groupes d’interactions ville-agriculture sont distingués : les interactions spatio-historiques entre nature, agriculture et ville, les interactions entre le système urbain actuel et l’agriculture, et enfin les interactions au sein du système agraire urbain. Il s’agit de repérer, dans l’ensemble de ces relations, ce qui explique la diversité des agricultures urbaines et les facteurs qui influencent leur devenir.

In the aftermath of failed urban renewal projects and the decline of central cities, community gardens have become increasingly popular in urban planning, public health, and environmental circles. However, gardens still occupy a tenuous and contradictory position in the city. While urban gardens are bounded spaces, they are also dynamic places where different understandings of (agri)culture, land use, and belonging are enacted and contested. In this paper, we identify three distinct ways in which gardens in a small Midwestern city are used and experienced by refugee gardeners and local officials: the material garden, the imagined garden, and the community's garden. The material garden, embodied in the biophysical aspects of the soil, seeds, and resources needed to cultivate plants, shapes what can grow in the garden and the transformations by refugee agricultural practices. While planners tend to see urban gardens as temporary spaces that can promote limited pathways of migrant incorporation, gardeners practice, and imagine gardening differently through social, cultural, and economic interactions. We argue that these practices challenge traditional understandings of nature and urban planning, and can promote inclusive understandings of agriculture, cities, and sustainability, embodied in the ideal of the community's garden.

La production maraîchère est une filière importante de l’agriculture urbaine et périurbaine en Afrique. En République démocratique du Congo, un projet d’horticulture urbaine et périurbaine a été mis en place avec l’appui technique de l’Organisation des Nations Unies pour l’alimentation et l’agriculture pour vulgariser des techniques de production et protection intégrées. Les techniques promues comprenaient l’usage des fertilisants naturels, des extraits de plantes à effet insecticide, des produits naturels de lutte contre les ravageurs, les associations et les rotations culturales, l’usage raisonné des pesticides en dernier recours, ainsi que l’utilisation de variétés résistantes aux maladies. Le modèle Logit a permis d’analyser les données d’enquête d’un échantillon de 246 maraîchers à Lubumbashi entre mars et juin 2016 pour identifier les facteurs favorisant l’adoption des techniques promues. L’appartenance à une association de maraîchers et la formation reçue en maraîchage sont deux facteurs clés qui influencent positivement et significativement l’adoption des techniques de production et protection intégrées, respectivement de 3,5 à 7 fois plus que les agriculteurs n’appartenant pas à une association ou n’ayant pas reçu de formation. Ces résultats suggèrent que la participation des agriculteurs à des ateliers de formation et à des groupes de discussion au travers de champs-écoles peut servir de catalyseur pour accroître l’adoption de techniques innovantes en maraîchage.

Alors qu’un nombre croissant d’études s’intéressent à l’agriculture urbaine, l’élevage urbain de porcs reste méconnu. Pourtant, il est présent dans de nombreuses villes du Sud et procure un revenu à de nombreuses familles. Cette étude visait à dépasser les analyses centrées sur des aspects techniques de ce type d’élevage pour s’intéresser plus largement au cadre social et spatial dans lequel des éleveurs élèvent des porcs en ville. Elle reposait sur une démarche empirique qui a permis de saisir les conditions du développement et du maintien de l’élevage de porcs dans la deuxième ville du Burkina Faso, Bobo-Dioulasso. Dans cet article, il est question des pratiques des éleveurs à petit effectif, et plus particulièrement du rôle que jouent les arrangements entre acteurs dans la mobilisation des ressources à la fois techniques et sociales qui sont nécessaires à la conduite et au maintien de ce type d’élevage. Les résultats soulignent que les éleveurs de porcs ont une logique de mobilité réduite : les arrangements qu’ils développent avec d’autres acteurs se basent sur une mise en invisibilité de l’élevage à la fois politique, spatiale et sociale, et les liens qu’ils développent pour accéder à des ressources externes sont ancrés dans le temps et dans un voisinage proche. L’environnement social et spatial au sein duquel ils évoluent est central pour la conduite quotidienne des élevages autant que pour leur pérennité à court et moyen terme.

L’accroissement démographique rapide des villes au sud de la méditerranée s’est accompagné d’une urbanisation consommatrice de terres fertiles. Toutefois des espaces interstitiels difficilement constructibles, entre les espaces construits, hébergent encore des exploitations agricoles. C’est le cas notamment des 3 vallées traversant l’agglomération de Meknès, au Maroc. Sur la base d’enquêtes auprès de 80 agriculteurs et 42 consommateurs et d’entretiens avec des décideurs et commerçants de cette ville, nous avons montré la diversité des systèmes de production présents dans la ville (maraîchage et élevage laitier et à viande principalement). Malgré la proximité de la ville, peu de produits sont vendus directement aux consommateurs. Dans le cas du maraîchage, une action urgente est à engager pour fournir de l’eau d’irrigation de qualité aux agriculteurs de ces vallées afin qu’ils renoncent au détournement des eaux usées produites par la ville. Les meilleurs atouts de l’agriculture dans les villes au sud de la Méditerranée sont d’une part de rendre possible l’existence de paysages verdoyants et ouverts permettant d’améliorer le bien-être des citadins et l’attractivité touristique de ces villes et d’autre part l’intérêt récent de citadins pour des produits de qualité vendus en circuit court.

Urban agriculture is developed in various forms depending on place on underlying ideologies. Montreuil, an ancient horticultural town known for its production of peaches, is today the subject of new agricultural initiatives. It's particularly the case in the neighborhood of Saint-Antoine - Murs à Pêches. Located in the high part of the city, this neighborhood, abandoned for a time by the urban planning processes, saw the multiplication of various forms of individual and collective appropriations. At stake is the desire to restore a function of agronomic production in the neighborhood, by maintaining a dying horticultural heritage, by developing permaculture projects, and by creating new spaces for meetings and exchanges in a framework of collective gardens and cultural projects. Broadcast by many association, these processes of appropriation respond to different approaches and objectives. Actions are fragmented, and new conflicts appear between associations, local population and the public authorities. The multiplication of these projects raises the question of the coordination of these citizens's initiatives and the difficulty of building a common space. [ABSTRACT FROM AUTHOR]

In cities of the Global North, where reign private or public ownership, vacant lots are reclaimed by communities for urban agriculture. Especially in Detroit, a shrinking city, massive land vacancy constitutes an opportunity to solve the tragedy of the non-commons in contemporary urbanization. Yet reclaiming the land for community urban agriculture does not entail the creation of urban commons, which necessitate complex processes of use and management. Based on a field survey conducted in Detroit for doctoral research and on a review of the literature on vacancy, urban agriculture and the common(s), this article demonstrates that building agricultural urban commons lies on three constitutive dimensions: occupying the land as territorial commons; cultivating the land with commons of knowledge; and governing the land as a common. The appearance of agricultural urban commons in Detroit can thus be interpreted as rising alternatives facing a political, economical, social and food crisis, that are nevertheless vulnerable to land grabbing for non-common uses.

This article aims to contribute to the debate on the place of agriculture within the cities and the evolution of urban agriculture (UA) typologies and their modes of appropriation by city dwellers. In particular, it investigates the representations of UA in the context of direct democracy experience : the participatory budget of the city of Rennes (Brittany) (2015-2016). The innovative dimension of this article is based on the source of discursive data that includes the proposals of the project promoters, and the technical departments and city dwellers comments and remarks. So it is possible to take into account the standpoint of a broader spectrum of actors that have multiple and sometimes discordant point of views. The principal tools adopted to carry out the analysis were discourses and lexical analysis. The main objective is to detach the actor's different positions on the integration of agriculture into urban spaces based on project proposals and commentaries related. In addition, it aims to point out the contribution of the representations and the standpoints of the linkage between men and land to the collective and collaborative production of UA. Social ties, agricultural production, education, so pluralities of arguments are aired and it is backdrop the desire to live together. However, the conditions for the UA development are discussed and several constraints emerge questioning the place of UA. [ABSTRACT FROM AUTHOR]

Urban agriculture, a widespread phenomenon across the world, invites us to new ways of analyzing two spheres traditionally considered separately: the city and agriculture. This article seeks to emphasize the importance of the agriurban system concept to analyze the complexity of cityagriculture interactions. Taking the case study of a West African city, its objective is to develop an interpretative framework of these interactions at the territorial level of a city and its region.We propose a systems approach based on the intersection of three groups of interactions: i) spatial and historical interactions between nature, agriculture and the city, ii) interactions between the current urban system and urban agriculture, and iii) interactions within the agricultural system. The aim is to identify how a variety of relationships between city and agriculture are developed and what is at stake for the durability of urban agriculture. Firstly, we show the historical contribution of agriculture to the development of the city: farmers have mobilized local resources to develop a diversity of urban or periurban farming activities. Secondly, analyzing the agriurban system reveals specific forms of urban governance and the weight of informality in the development of urban agriculture. Finally, our analysis highlights the weight of croplivestock and ruralurban interactions in the functioning of the agriurban system. [ABSTRACT FROM AUTHOR]

Avec la croissance de la population urbaine mondiale, les rôles que pourraient jouer les agricultures urbaines dans les villes de demain posent question. L’Egypte, qui a connu une urbanisation très rapide au cours du siècle dernier, semble abriter une importante diversité d’exploitations urbaines et périurbaines. La mégalopole du Grand Caire, avec ses 20 millions d’habitants, ne fait pas exception et profite de la présence de fermes, dont une partie contribue à l’approvisionnement en lait de la ville. Relevant de l’économie informelle, la littérature est presque inexistante quant à leurs structures, fonctionnements, dynamiques et perspectives. Cet article décrit les principaux systèmes familiaux du secteur laitier informel du Caire, afin de mieux cerner leurs contraintes et leurs opportunités. Les données collectées au cours d’entretiens auprès de 73 éleveurs du Caire ont permis de réaliser une typologie de ces systèmes en se basant sur leurs caractéristiques structurelles, techniques, familiales et économiques. Deux grandes catégories ont été identifiées : les agroéleveurs intégrant agriculture et élevage, et les éleveurs hors-sol. Chacune de ces catégories a été divisée en deux types, à partir d’un gradient de la taille. Dans tous les cas, la satisfaction des besoins alimentaires familiaux a primé. Le lait de bufflonne était le lait le plus produit et la commercialisation des surplus de lait frais passait par des circuits courts. Bien que rendant des services à la ville, ces exploitations affrontaient de nombreuses contraintes (coûts élevés des intrants agricoles, pression foncière, faible disponibilité des terres agricoles, parmi d’autres) qui remettaient en question leur subsistance à moyen terme.
