Abstract: The postdoctorate position is part of the VINIoT project of Interreg Sudoe. The objective of this project is to propose a new precision viticulture service based on an IoT (Internet Of Things) sensor network. This service will enable SMEs in the wine sector in the SUDOE area to monitor their vineyards in real time, remotely and at different precision scales (grape, plant, plot and vineyard). The aim is to accurately assess the state of the vine, from the maturity of the berries to the early detection of the appearance of diseases or water stress. The first year is dedicated to the study on the leaf scale with a precise monitoring of the potted vine. The other years are devoted to the application on the scale of the agricultural field.
The Research Team ‘optical sensors for complex media’ (COMIC) of the research unit UMR ITAP is in charge of proposing optical instrument solutions for vine monitoring in a water stress context. The objective of the COMIC team is to study the detection limits of optical instruments to monitor the state of the vine.
Experiments will be carried out during the three years of the project in partnership with other INRAE teams (UMR LEPSE, UE Pech-Rouge). The first step will consist of studying whether the detection of water stress in grapevines is possible with tools usually used in the laboratory, in particular hyperspectral imaging. The second step will then be to consider less expensive sensor solutions adapted to field constraints for the use of IoT objects. The COMIC team will also provide the necessary scientific support to the collaborators from a data analysis point of view and on the discussions of technological choices.
The post-doctoral student will coordinate the scientific aspects of the part of the project concerning the COMIC team.
The missions will be:
– To manage the experiments (organization, planning the needs of material and human resources).
– To conceive experimental designs and to establish protocols for hyperspectral image acquisition, NIR spectroscopy and other phenotyping tools
– To analyze data from different experiments.
– To valorize results through the writing of scientific articles.
– To participate in the meetings between the different collaborators of the project: AIMEN (Spain), Agacal (Spain), ADVID (Portugal), IFV (France), AGAMELARIOJA (Gobierno de la Rioja), FEUGA (Spain).
