The contribution of agent-based simulations to conservation management on a Natura 2000 site.

The conservation of biodiversity today must include the participation and support of local stakeholders. Natura 2000 can be considered as a conservation system that, in its application in most EU countries, relies on the participation of local stakeholders. Our study proposes a scientific method for participatory modelling, with the aim of contributing to the conservation management of habitats and species at a Natura 2000 site (Crozon Peninsula, Bretagne, France) that is representative of in landuse changes in coastal areas. We make use of companion modelling and its associated tools (scenario-planning, GIS, multi-agent modelling and simulations) to consider possible futures through the co-construction of management scenarios and the understanding of their consequences on different indicators of biodiversity status (habitats, avifauna, flora). The maintenance of human activities as they have been carried out since the creation of the Natura 2000s zone allows the biodiversity values to remain stable. Extensive agricultural activities have been shown to be essential to this maintenance, whereas management sustained by the multiplication of conservation actions brings about variable results according to the indicators. None of the scenarios has a positive incidence on the set of indicators. However, an understanding of the modelling system and the results of the simulations allow for the refining of the selection of conservation actions in relation to the species to be preserved.

Location-and temporal-based services for nature-society interaction regulation

With the surge of mobile devices and applications, knowledge base browsing and querying facilities must be adapted to new kinds of users and services. Space and time databases are concerned and as such are the subject of this article. Within a mobile context, data retrieval services must take the location of the call into consideration as regards space and time, insofar many pieces of information do depend on ‘where’ and ‘when’ constraints. We present here with a general object model dedicated to specifying time properties. The novel aspects of our proposal consist of three main points. First, the temporal object model stands as a pivot model, and all the more leverages interoperability between software applications, since it extends common standards, such as ISO 19108 and iCalendar. Second, we accompany the object model with a formal grammar close to natural languages, which helps end users in managing and checking temporal object instances. Finally, our proposal focuses on intensional temporal expressions instead of extensional sets of concrete calendar dates. This allows to express semantic aspects – namely for periodic (cyclic) events – which remain hidden and not computable when only a series of dates are given. We evoke two kinds of applications for which our model is beneficial; one concerns services called by human users and the other addresses calls placed by software agents e.g. in a multi-agent system for instance within a simulation context.

Infrastructures de données géographiques et observatoires de recherche en environnement - Un exemple de mise en œuvre

Françoise Gourmelon; Mathias Rouan; Jean Nabucet

Cet article decrit une Infrastructure de Donnees Geographiques (Indigeo) elaboree dans un cadre academique associant un laboratoire de recherche et plusieurs observatoires en environnement. La methode Agile utilisee conduit a une solution exploitant des outils libres, et reposant sur un catalogue de metadonnees et un serveur de donnees georeferencees, adosses a un portail web disposant de deux visualiseurs cartographiques dont l’un (geoCMS) prend en charge la dimension temporelle des donnees. Conformement aux recommandations de l’Open Science, Indigeo met actuellement a disposition en acces libre plus de 500 couches d’informations et leurs metadonnees et permet la co-visualisation des donnees d’une quinzaine d’IDG generalistes ou thematiques interoperables. Elle offre aussi une plus-value pour l’analyse de donnees spatio-temporelles. Neanmoins si Indigeo rend actuellement plusieurs services de stockage, d’analyse, de partage et de porter a connaissances de l’information geographique scientifique, elle demeure sous-utilisee en termes d’alimentation du catalogue et de diffusion. Les perspectives d’evolution d’Indigeo sont discutees afin de contrecarrer sa sous-utilisation et son relatif isolement vis-a-vis des IDG institutionnelles et des infrastructures de recherche en environnement

Modélisation d’accompagnement en gestion conservatoire - Expérimentation au sein du réseau français Natura 2000

Hélène Dupont; Françoise Gourmelon; Mathias Rouan; Isabelle Le Viol; Christian Kerbiriou

Dans le contexte dynamique des changements d’usages des sols sur la zone cotiere, l’etude experimente la modelisation d’accompagnement en vue de contribuer a la gestion conservatoire des habitats et des especes sur un site (presqu’ile de Crozon, Bretagne, France). Les objectifs sont d’identifier et de partager les attentes, les contraintes et les pratiques des acteurs locaux impliques dans la mise en œuvre de Natura 2000, de les sensibiliser aux dynamiques ecologiques et sociales susceptibles de se derouler dans un futur proche par la co-construction de scenarios. Le processus iteratif mis en œuvre permet de combiner les savoirs experts et locaux a toutes les etapes du processus et conduit a divers resultats dont des indicateurs d’etat de la biodiversite en fonction de plusieurs scenarios de gestion. L’experimentation demontre non seulement l’interet operationnel de la modelisation d’accompagnement dans une scene de gestion adaptee qui confere une legitimite a la demarche, mais aussi la pertinence de son emprise locale.
