THE EFFECTS OF CAP REFORM ON THE PERIURBAN AGRICULTURAL AREA IN THE PLAIN OF THE CITY OF ASSISI (CENTRAL ITALY)

In periurban areas agriculture can assume a multifunctional role that includes landscape conservation, sustainable resource management, biodiversity conservation, leisure activities, and can also maintain adequate conditions in densely populated areas for a safe and habitable environment. This study investigates the effects of the introduction of single farm payment on the periurban agricultural area in the plain of the City of Assisi, an area with a strong landscape value. A survey was carried out to determine: changes in production, changes on farm incomes, structural adjustments, the level of multifunctionality of periurban agriculture. Moreover, a survey of 355 residents was made to assess their willingness to pay for some positive externalities of the agriculture in this area. The results suggest the low-impact of reform on farms and the existence of a significant demand for environmental and social functions of the periurban agriculture of this region.Periurban Agriculture, Cap Reform, Economic Valuation, Contingent Valuation, Assisi, Agricultural and Food Policy, Research Methods/ Statistical Methods, Q10, Q18,

Business models in urban farming: A comparative analysis of case studies from Spain, Italy and Germany

The “Urban Agriculture Europe” EU COST-Action (2012–2016) has shown that the complexity of urban agriculture (UA) is hardly compressible into classic business management models and has proposed new management models, such as the Business Model Canvas (BMC). Business models of UA have to be different from rural ones. In particular, factors such as differentiation and diversification, but also low cost-oriented specialisation, are characteristic and necessary business models for UA to stay profitable in the long term under challenging city conditions. This paper aims to highlight how farm enterprises have to adjust to urban conditions by stepping into appropriate business models aiming to stay competitive and profitable, and how the BMC is useful to analyse their organisation and performance, both economically and socially. The paper offers an inter-regional analysis of UA enterprises located in Spain, Italy, and Germany, which are further subdivided into: local food, leisure, educational, social, therapeutic, agri-environmental, cultural heritage and experimental farms. The analysis demonstrates that UA is differentially adjusted to specific urban conditions and that the BMC is useful for analysing urban farming. Heterogeneous local food farms and the integration of local and organic food production in social farming business models are most frequent in our case studies

An analysis of current integration of urban agriculture and domestic garden into urban planning: the case of Île-De-France Region

International audienceIn this contribution we question the role that urban agriculture and private garden have in the city fabric. On one hand, more than a passing trend, urban agriculture (UA) has become a part of modern cities. According to some authors, it provides some ecosystem services (well-being, food, carbon storage, water captation, biodiversity…) contributing to create more livable cities (Stella et al., 2022). Local stakeholders enhance and implement agricultural activities into urban and periurban areas to expect different functions. Although these functions are recognized, they cannot be generalized. Not all forms of urban agriculture provide the same services. Unfortunately, reliable methodologies to characterize and quantify these services are still lacking. On the other hand, Urban Domestic Gardens (UDG) – understand as private houses’ yards – are an important part of urban green infrastructures (Mathieu et al., 2007) and also contribute to ecosystem services provision (Cameron et al., 2012). At urban planning scale, those functions -and particularly the food auto-production one- are still not recognized as they should by cities to enhance local resilience. How municipalities take into account UA and UDG into territorial project ? Which issues and functions are related to UA and UDG ? How does territorial context determine the consideration for those functions ? Based on the analysis of urban plans, we detected the role attributed to urban agriculture and UDG. We carried out a thematic analysis following an occurrence analysis of key words (collective or private or community or allotment garden, urban or micro farms, roof top, etc…) within the plans (52 for UA and 200 for UDG) focusing on the Ile de France region. We selected this area based on several criteria. First is the region that concentrates the most UA projects, around 900 according to the French Professional Urban Agriculture observatory. Second, it is the most populated area and most of the population lives in an urban unit. Finally, the urban tissue is very heterogeneous including many private gardens. We also realized a statistical processing cross-referencing the results to external and territorial context. We delved deeper withsome interviews to local stakeholders (10 for UA and 17 for UDG). It emerges that the main issues related to urban agriculture and private garden are : 1-Urban agriculture and private gardens contribute to the resilience of cities in the face of global changes in particular « urban greenery » and « climate change mitigation ».2- Re-territorialization of agriculture is related to the possibility for accessing to local food in order to promote food production resiliency.We note that some factors influence the consideration of those issues and urban agriculture and private gardens. Generally speaking, allotment gardens are the forms of UA best taken into account in the planning document (Consalès et al., 2018) thanks to their origin, legal protection and size. Their are more related to quality of life or environmental issues (ex. biodiversity or green and blue grid). The community garden or urban microfarms are more related to social cohesion and educational issues but are less present in those documents. Perceptions of UDG are ambivalent: between a land available for urban densification and a biodiversity corridor that needs to be preserved. We also observed correlations between the socio-political profile of municipalities and the integration of those topics into the territorial project. We noted that these topics are treated more in the presentation part of the plan that remain more declarative than operational and regulatory. There seem to be contextual and technical constraints on the implementation of regulatory mechanisms to preserve and develop these areas

Evaluation des services écosystémiques fournis par les sols de micro-fermes urbaines : Méthodologie et retours d'expériences

International audienceUrban micro-farms are rapidly developping driven by NGOs and supported by citizen and local politics. This new object of research wasdefined in two different contexts: urban and peri-urban/rural environments (Daniel 2019; Morel et al. 2017). In urban environments micro-farmare small scale farms (less than 1.5EFT per ha), involving often volunteers and generating a diversity of activities. The different functionsexpected from them (food provisioning, teaching support, social and cultural activity, water retention, valorization of wastes and landscape...)are directly linked to a diversity of ecosystem services that they can deliver. Nevertheless, only a few studies focus on micro-farms and donot allow a sufficient understanding of the ecosystem services that they can deliver. In parallel, the involvement of farmers in the evaluation ofecosystem services seems to be a great opportunity, if not a necessary condition. Based on this observation, the research project SEMOIRS(2018 – 2020), funded by ADEME, aims to evaluate ecosystem services delivered by urban micro-farms. The aim of this article is to presentand discuss the methodology of the project. Seven micro-farms were studied during two years: 4 were located at the soil level and 3 at rooftoplevel [see table 1]. Five ecosystem services were studied: food production (quantity and quality), biodiversity supporting (flora, fauna, andmicroorganisms), regulation (water catchment and quality, local climate regulation, use of urban waste and carbon storage) as well as socialand cultural services. A set of indicators was set up [see table 3] based on three types of data : (i) participative measurements achieved bythe farmers themselves, (ii) field measurements (including a questionnaire for micro-farm users) performed by researchers and (iii) externaldata, based on laboratory measurements, data bases, literature etc. The study has shown that all of the seven soils of micro-farms are dee-ply disrupted, from removed topsoil to isolatic Technosol (IUSS Working Group WRB, 2014). The methodology used raised key questionsregarding ecosystem services evaluation. (i) First, there is a trade-off to be dealt within the participative approach, between the targetedprecision of data needed on the one hand and the time spent by stakeholders for the measurement on the other hand. Despite these limits,the participative approach allows for a better understanding of the ecosystem services drivers by the farmers as well as collecting data notaccessible otherwise. (ii) Second, the choice of references to which we compare the ecosystem services delivered by urban micro-farmsis crucial. In the project, three reference were considered: professional vegetables farms, other urban agriculture forms and other type ofurban green spaces. We identified a serious lack of reference data on the considered ecosystem services that limits the comparison and thediscussion. (iii) Finally, our work raised the question of the scale at which to study different ecosystem services, as the different ecosystemservices operate at different spatial scales. Four scale were used here: soil, farm, neighborhood and the territory (here, the city; see figure 3).Encompassing different scales raises however the questions of a common study scale and that of the methodology needed to change fromone scale to another. However, despite those limits and perspectives the proposed methodology, relying partly on a participatory approach,appears promising to evaluate the ecosystem services provided by urban micro-farmsObjet récent de recherche, les micro-fermes urbaines sont aujourd'hui en plein essor, portées par un mouvement associatif, citoyen, entrepreneurial et politique relativement important. Ces fermes sont définies par leurs petites surfaces (moins d'1,5 ha paractif), l'implication de bénévoles et une diversité d'activités. Différentes fonctions sont ainsi associées à ces lieux (éducatives, productions alimentaires, loisirs etc.), faisant de ces micro-fermes urbaines des nouveaux types d'espaces végétalisés en ville susceptibles de fournir de multiples services écosystémiques. Néanmoins, le manque de connaissances actuelles sur le sujet ne permet pas d'appréhender dans le détail l'importance des services rendus. Par ailleurs, l'implication des parties prenantes dans une telle évaluation parait être un enjeu essentiel afin de comprendre les déterminants et facteurs d'influence de ces fermes ; les porteurs de projet étant eux-mêmes, par exemple, créateurs de savoirs et de pratiques agronomiques originales en s'adaptant aux contraintes du milieu urbain. L'objectif de cet article est de décrire et de discuter une méthodologie d'étude des services écosystémiques rendus par les micro-fermes urbaines, mise en oeuvre dans le cadre du projet SEMOIRS (Evaluation des Services Ecosystémiques rendus par les MicrO-fermes urbaInes et leurs Sols ; 2018 –2020) financé par l'ADEME. Au sein de ce projet, 7 micro-fermes et leurs sols à Paris et en petite couronne ont été étudiés durant deux ans. Ces fermes situées en toiture (3) et de plain-pied (4) sont illustratives de la diversité de cette forme d'agriculture urbaine. Des indicateurs ont été identifiés et sélectionnés pour étudier les différents services : (i) service d'approvisionnement alimentaire (rendement et qualité de la production), (ii) des services de régulation (rétention d'eau, qualité de l'eau de percolation, recyclage de résidus urbains, stockage de carbone dans le sol, fourniture de nutriments), (iii) service de support de biodiversité et (iv) des services culturels (impact sur l'apprentissage, le bien-être, l'esthétique) et paysagers. Trois types de méthodes ont été mobilisés pour acquérir les données : (1) participatives, (2) relevés, observations et enquêtes de terrain ainsi que (3) des mesures dites externes (en laboratoire ou à partir de bases de données). Après avoir présenté les indicateurs et méthodes utilisés par service, l'article discute de cette méthodologie et des perspectives pour l'étude de projets en milieu urbain. Cette approche participative couplée à une démarche d'acquisition de données « externes » paraît pertinente et génératrice de savoirs tant sur les services rendus que sur leurs facteurs d'influence
