Sébastien Giorgis

Architecte DPLG – Urbaniste SFU – Membre du Comité Scientifique International de l’ICOMOS – Cultural Landscapes

Sébastien Giorgis is a DPLG architect, SFU urban planner and landscape designer. He is one of the founding members of the Collectif PAP (Paysages de l’Après Pétrole) and a member of the International Scientific Council of ICOMOS IFLA-Cultural Landscapes. In 1998 he founded the NGO VOLUBILIS, a Mediterranean network for cities and landscapes.

His studio, Agence Paysages in Avignon, was conceived from the outset as a multidisciplinary team (landscape architects, architects, naturalists, urban planners, agronomists, geographers, visual artists), thus affirming his conviction that the social, cultural, spatial, technical and functional complexity of the city, landscapes and the territory calls for a transversal approach. His work has been distinguished by various national prizes and awards.

He has taught at the École Nationale Supérieure du Paysage de Versailles, and has lectured in various architecture and landscape schools. Since 2014, he is Deputy Mayor of Avignon, responsible for territorial and tourist appeal, historical heritage and major events.

Adrien Rusch

Ecology Researcher at INRAe

Adrien Rusch is a researcher in agroecology at INRAE.

After studying agronomy and completing a thesis in agroecology, he is focusing his research on the relationships between agriculture, biodiversity and ecosystem functioning. Using food web ecology and landscape ecology approaches, he is particularly interested in understanding how agricultural practices and changes in the structure of agricultural landscapes affect community structure, trophic interactions and the production of various ecosystem services (e.g. natural regulation of pests, degradation of organic matter).

He is also interested in the multifunctionality of agricultural landscapes through the analysis of landscape structures that promote synergies and limit antagonisms between biodiversity services. The objective of his work is to participate in the development and implementation of agricultural land use strategies that reconcile biodiversity preservation and economically viable agricultural activities.

Eric L’Helgoualch

Chamber of Agriculture of Vaucluse (Southern Rhone Valley)

Eric L’Helgoualch helps farmers and winegrowers to better understand their agroecosystem in order to promote its balance.

After having led the Sustainable Development Plans in Vaucluse and advised many farmers in conversion to organic farming, he became the national referent for organic viticulture for the network of chambers of agriculture, and later on in charge of the DEPHY viticulture groups for the Mediterranean arc. At the same time, he set up experiments and networks on the impact of grass strips and hedges on the natural environment (water quality, flora, fauna) and accompanied hedge establishment projects.

This background and contacts have given him recognised competence in the field of biodiversity in agriculture.

Lilian Bérillon

Nursery Lilian Bérillon

Son and grandson of nurserymen in Vaucluse, Lilian Bérillon was immersed in the world of agriculture and wine nurseries from an early age.

As a wine lover, he first studied viticulture and oenology and then continued with a BTS in Wine Trade. He completed his training with a third year of Management and Marketing in Suze-La-Rousse.

In 1998, he developed his nursery business on the already existing model: hyperproduction of plants, bartering on the Platanes market square in Carpentras, the race for profitability and volume. In 1999, he became president of the Vaucluse union of wood and vine plant producers, the leading plant producing department in France.

Over time, he became aware of serious health problems in the vineyard: wood and vine diseases, and the decline of certain vineyards without any apparent explanation. He started questionning a large number of practices and tried to transmit a qualitative vision of the plant material.

In 2003, Lilian resigned from his position as national vice-president of the union and decided to follow his convictions: to create a model that respects plant material for winegrowers who want to produce wines that express their terroirs.

Prof. Emmanuelle Porcher

MNHN, Deputy Director of CESCO

Prof. Emmanuelle Porcher is professor of ecology at the Muséum national d’Histoire naturelle and director of the Centre d’Ecologie et des Sciences de la Conservation.

Her research focuses on the relationship between agriculture and biodiversity and how agricultural practices influence wildlife biodiversity, but also how this biodiversity can be useful to farmers, for example by working on pollination services or soil fauna.

Her studies are based on “classic” experimental ecology, but also on participatory science, which involves researchers and other citizens in research programmes. For example, it is in charge of the scientific development of the Observatoire Agricole de la Biodiversité (http://observatoire-agricole-biodiversite.fr/), a biodiversity monitoring system for and by farmers.

Georges Truc

Geologist & Hydrogeologist

Former geologist and hydrogeologist, teacher and researcher at the Claude-Bernard University in Lyon (1965 – 2005), Georges Truc is originally from Visan, a small wine-growing commune in the Haut Vaucluse (Enclave des Papes, Southern Rhone Valley).

Specialist in the Tertiary of the Rhone Valley, he quickly directed his interest towards evaporites (salt, gypsum, etc.) in collaboration with the Museum of Natural History in Paris and Elf-Aquitaine. Finally, it was the alteration and transformation phenomena affecting the Tertiary and Quaternary paleosols in the circum-Mediterranean area that took up most of his activity.

Passionate about wine and geosensory tasting, he can easily be described as an Oenogeologist, devoting his time to the study of the links between the subsoil, the vine and the wine.
