Exploit biodiversity in viticultural systems to reduce pest damage and pesticide use, and increase ecosystem services provision: the Biovine project

2019

International audience; Organic vineyards still rely on large external inputs to control harmful organisms (i.e., pests). The BIOVINE project aims to develop natural solutions based on plant diversity to control pests and reduce pesticide dependence. The capability of plants of increasing the ecosystem resistance to pests and invasive species is a well-known ecosystem service. However, monocultures (including vineyards) do not exploit the potential of plant diversity. BIOVINE aims to develop new viticultural systems based on increased plant diversity within (e.g., cover crops) and/or around (e.g., hedges, vegetation spots) vineyards by planting selected plant species for the control of arth…

Impact d'anciennes activités minières sur la zone critique : exemple des mines de plomb et d'argent de Peisey-Nancroix (19ème-20ème siècle)

2018

International audience; A better understanding of long-term trace metals dispersal and their bioavailability in the critical zone is required to anticipate future impacts of present-day mining activity. The Pb-Ag district of Peisey-Nancroix (northern French Alps) is an excellent target to study the long-term environmental impacts (> 150 years) of former mines and trace metal dispersal in the critical zone, considering that every steps of the mining cycle, from ore extraction to ore processing, were located on a few hectares site that has been unmodified since mine closure in 1866 (no reclamation). A cross-disciplinary study is conducted using several proxies (ore, waste dumps, soil, water, …

Zur Geschichte der nacheiszeitlichen Umwelt und der Kulturpflanzen im Land Brandenburg

2018

International audience; The results of pollenanalytical and archaeobotanical studies presented here show the development of veg-etation in the state of Brandenburg, which was characterized by the climate and the associated natural spread of plants as well as the use of the resource forest by man.The plant food of humans was first obtained by gathering and, since the beginning of permanent settle-ment in the Neolithic period, mainly by means of agriculture. The cultivation of plants continued over the millennia, with most archaeological cultures showing their typical inventory of crops. The dynamics of these developments require further research, as there are still many spatial and temporal …

Conception de Stratégies durables de gestion des Adventices dans un contexte de Changement : le projet CoSAC

2020

International audience; La flore adventice est nuisible pour la production agricole mais est aussi l’un des piliers de la biodiversité dans les paysages agricoles.La réduction de l'usage d'herbicides demandée par le plan ECOPHYTO, implique que la gestion des adventices dorénavant combinel'ensemble des leviers du système de culture. L'objectif du projet CoSAC était de concevoir, d’évaluer et de promouvoir des systèmesde culture conciliant réduction d'usage des herbicides, maintien de la production agricole et préservation de la biodiversité. Pourcela, il était nécessaire de : (1) mieux comprendre et prédire le fonctionnement de l'agroécosystème, notamment les mécanismesbiophysiques régissant…

Holocene fires in the central European lowlands and the role of humans

2018

International audience; A major debate concerns the questions of when and to what extent humans affected regional landscapes, especially land cover and associated geomorphological dynamics, significantly beyond natural variability. Fire is both, a natural component of many climate zones and ecosystems around the globe and also closely related to human land cover change. Humans clearly affected natural fire regimes and landscapes in the most recent centuries, acting as prime ignition triggers and later fire suppressors, while Holocene trends in sedimentary charcoal have been mainly associated with climatic factors and partly with Neolithic land cover change. However, little is known since wh…
