mougeot, 2006; un habitat, 2014). as such, ua must be understood as one of planning’s current “models-in-circulation” (roy and ong, 2011), characterised by the traveling of ideas and policies in a globalised world (healey, 2013). ua operates at a diversity of scales and engages a variety of actors. yet, as a model-in-circulation, only some of the ways in which ua is practiced are promoted globally and influence the way ua is perceived, thus disregarding ua’s highly specific manifestations in different social/economic/political contexts around the world. we use a critical transnational perspective for a qualitative analysis of collective (rather than individual) ua practices happening in small-scale, left-over public spaces in three very different locations in latin america and europe (bogotá and medellin in colombia, and vienna in austria) to gain insights into how policies and initiatives inspired by typical models-in-circulation affect the situation on ground. the analysis shows that the reliance on such models can act like a filter impeding the acknowledgment that actors, objectives and barriers for ua practices are more complex, nuanced and multifaceted than those that a simple model can contain. as a result the benefits ua can yield are only partially attained. the conceptual device of translocal is subsequently formulated as one conveying the traveling of ideas locally, which can enrich and root models-in-circulation. tags: agriculture_urbaine digging for the roots of urban gardening behaviours 24/06/2018 non classé agriculture_urbaine eric duchemin urban green spaces make a significant contribution to the social and ecological environment in cities, and the decisions of green space managers have direct impacts at both local and city scales. however most studies have focussed on public green spaces, despite privately managed gardens collectively forming a large proportion of urban green. the aim of this qualitative paper is to understand why people become involved in gardening and why they choose environmentally friendly gardening practices. we conducted semi-structured interviews with 23 gardeners in lausanne, switzerland and analysed them according to their content. three major themes emerged as motivations for gardening: wellbeing, social aspects, and outputs (both tangible, such as food, and intangible, such as the feeling of having produced food). motivations for gardening practices were grouped into extrinsic factors, such as practical constraints, inspiration from neighbours, following regulations, and social controls; and intrinsic, which were primarily based on knowledge and experience. our results provide some evidence of the tangible and beneficial outcomes of gardening and provide additional support to urban decision makers with an interest in the management of urban green spaces. tags: agriculture_urbaine the role of urban agriculture as a nature-based solution: a review for developing a system 18/06/2018 non classé agriculture_urbaine eric duchemin urbanization and achieving sustainable agriculture are both major societal challenges. by reducing food miles and connecting people with nature, food cultivation in cities has several major advantages. however, due to further urban development (peri-) urban agriculture (upa) is under threat. to strengthen upa, we argue for considering upa as a nature-based solution (nbs) supporting systemic approaches for societal challenges. however, academic knowledge on upa’s contribution to various societal challenges of urbanization is still fragmented. this study addresses the gap by conducting a systemic literature review, incorporating 166 academic articles focusing on the global north. the results of the review show that upa contributes to ten key societal challenges of urbanization: climate change, food security, biodiversity and ecosystem services, agricultural intensification, resource efficiency, urban renewal and regeneration, land management, public health, social cohesion, and economic growth. the value of upa is its multifunctionality in providing social, economic and environmental co-benefits and ecosystem services. when implementing upa, social, institutional, economic, technical, geographical, and ecological drivers and constraints need to be considered. to upscale upa successfully, the study develops an integrative assessment framework for evaluating the implementation and impact efficiency of upa. this framework should be tested based on the example of edible cities tags: agriculture_urbaine let them eat kale : the misplaced of food access 04/06/2018 non classé agriculture_urbaine eric duchemin this article examines the emergence of food access as a policy issue, current approaches to increasing food access, and possible alternatives. part i discusses the development of the current food access narrative, focusing on its appeal to policymakers, urban planners, and public health officials. part ii describes policies to increase access to food retail. part iii reviews research on the relationship between food retail and health outcomes. part iv examines why increasing food access persists as a policy goal despite its demonstrated failure to reduce health inequities. finally, part v proposes alternative strategies for reducing economic and health disparities within food systems. tags: agriculture_urbaine remote sensing data and methods for identifying urban and peri-urban smallholder agriculture in developing countries and in the united states – reference module in earth systems and environmental sciences/comprehensive remote sensing – 9.19 30/05/2018 non classé agriculture_urbaine eric duchemin the world has experienced rapid urbanization over the past five decades, with resulting substantial changes to the food system. strong urbanization is associated with economic growth, which allows for investment in substantial increases in energy, water, and land used in intensive agriculture required to support urban populations. given the cost of moving goods from distant regions, there has been a growth of small-scale agriculture within urban areas to meet the needs of its population. in this paper, we will describe satellite remote sensing data and methods that can identify urban and peri-urban farms and gardens in the united states and in developing countries, starting with global approaches and then providing case studies that explore different techniques. an examination of the increasing importance of local food to urban populations, and the role remote sensing can play in identifying where urban farming is occurring and its change through time will conclude the article. tags: agriculture_urbaine the impact of royal botanic gardens’ community greening program on perceived health, wellbeing, and social benefits in social housing communities in nsw: research report. | tonia gray and kumara ward – academia.edu 18/05/2018 non classé agriculture_urbaine eric duchemin community gardening is one of myriad ways in which humans and nature interact. a primary objective of the study was to ascertain th
