Pełny tekst źródłaViticulture, like any other agricultural activity, has impacts on the environment, but over time,environmental concerns have intensified, and winemakers have changed their practices to integrate new criteria into their farming systems. Consumers, on their side, are more and more sensitive to these environmental issues, they are concerned about the impact of their purchases and show concern about the effects of agriculture on health and the environment. One way to change agricultural practices and to integrate new actors into the systems is through participatory approaches. These often include researchers and producers, but to date few approaches have been interested in integrating consumers into the reflection that winegrowers have on the integration of more environmentally friendly practices in their vineyards.This thesis has therefore developed a participatory approach with winegrowers, consumers and researchers in several stages (diagnosis, validation, implementation of workshops). However, the difficulty in mobilizing professional actors and their divergent interests at the collective and individual levels, as well as the lack of knowledge of consumers, can hinder this type of process. Moreover, it seems essential to couple the reflections on the deployment of practices with that of their promotion and communication to consumers to make them aware of the environmental issues in the vineyards and to support this change in practices over time

Pełny tekst źródłaTo understand transfers of pesticides, the catchment of Rouffach (Haut-Rhin, France) and two plots inside (weeded chemically in a full and grassed inter-row on two with weeding on the row) are equipped to quantify the fluxes of 17 active matters in continuously during approximately 6 months per year. The measurement instrumentation of the site is validated by identifying the possible sources of errors (uncertainty and bias) during the evaluation of the pesticide concentration. From a method of decomposition of the measurement acquisition and experiments, we evaluate bias associated with data. The results achieved over the two years of monitoring (2003-2004) with opposite rainfalls enable us to emphasize the principal processes implied in pesticide transfers on this type of medium. All the compounds are detected at least once in 2003 or 2004. The average concentrations of the majority of the pesticides are strong after the first episodes according to application. But the pluviometric factors can make increase strongly the concentrations even several months after the application if the molecules are still mobilizable by runoff. The majority of the compounds are also detected during events with runoff on the impermeable zones, without plot runoff. The unfavourable factors mainly explaining the strong concentrations measured for some pesticides would be an input generalized in time and space and/or properties supporting a durable availability in the zone of interface soil-runoff. We finally validated, by using a simplified hydrological model, the assumption that the response time of the pesticide can be influenced, after the first major event, by the space distribution of the compound input(s) in a prevalent way and, for the following events, by the space distribution plus the pesticide state (desorption/degradation) moving in time according to its characteristics. The total fluxes exported with runoff at catchment outlet spread from 0 to 0,62 % of the applied quantity. The critical events from their hydrological characteristics (intensity, duration) and their situation with respect to the inputs constitute the main part of the exported quantities. The comprehension of pesticides behaviour enables us to propose solutions to limit pesticides transfers at catchment scale

Pełny tekst źródłaThis work aims to meet the vineyard managers' needs for information, using very high spatial resolution aerial images. Three methods have been developed and compared for vine plot detection. They are based on oriented and periodical texture recognition using either a cooccurrence analysis (Haralick's contrast index) or a frequency analysis (Fourier transform and Gabor's filters). The Fourier transform calculation on a sliding window provides the best results with plot segmentation in polygons as well as a precise estimation of row orientation and interrow distance. These characteristics enable the extraction and detailed study of each vine row, designed to: 1) improve definition of plots contours, 2) detect missing vine plants and 3) characterize inter-rows. Most of the users' needs have been met during this PhD study thanks to the implementation of a semi-automatic tool for vine plot detection, segmentation and characterization
