Повний текст джерелаViticulture, 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

Повний текст джерелаTo 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

Повний текст джерелаThis 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

Повний текст джерелаVoluntary Environmental Approaches (VEA) are considered as all the firm free contracts aiming at improving their environmental performance, beyond legal requirements, in the limits of a formal or informal system. The dynamics of their expansion and their diversity leads to open an economical and ecological work in order to analyse them, selecting the acceptibility criteria, rather than the ecological one. We present an analysis of the various conditions of VEA emergence and durability in the agricultural sector, especially in wine growing and fruit arboriculture. As a matter of fact, these two sectors are concerned by the non-point source pollution due to chemical products. In order to cope with this major environmental issue, the actors have chosen two VEA models : organic farming and integrated farming. Starting from the economics of conventions theoretical foundations, we build an analysis that fits with the environmental problem, articulating possible worlds of environmental protecting production and environmental conventions. It allows us to focus on the distinction between the two VEA types in both processes

Повний текст джерелаImpacts, the preservation of nature, the safety and security of products, and chemical or nuclear installations,. . . The dynamics of this standardisation process (the definition of technical and legal standards) the development and internationalisation of environmental policies (setting up of appropriate regulatory bodies) has resulted, at least in part, in an internationalisation by those responsible for the pollution of the social costs related to the environmental damage caused. Indeed, these dispositions have mostly been lobbied by the numerous associations or environmental and or ecological movements, with the assistance of the lawyers, the support of science and economics professors, and the back up of the media, to the extent that public opinion still today is significant in shaping environmental action, and plays a crucial role for those companies accused of misdemeanours. As a result, Electricite de France, one of the largest electricity companies in the world and one of the last state monopolies, has had to adapt on three fronts : internal, national and international. At each of these three levels, the environment is one of the major factors that EDF is required to consider in order to deal with its development and future. Such environmental problems that EDF must face are obviously related to the activities of the company which generates almost all the electric energy of France, as well as supplying and distributing it to each customer's home. Furthermore, through its undertakings abroad : direct sales of electricity in Europe, export and operations of electricity generating systems, technical and financial engineering, or its "diplomatic" activity through its participation in E7, EDF is required to meet a global challenge : that of sustainable development. Hence, the environment plays a significant role with implications across the board of EDF's activities and strategy, whether in technical choices for generation or marketing of…

Повний текст джерелаThe purpose of the present research is to find out the conditions which enable a logistics service provider to act as a middleman in a supply chain in the context of sustainable development. Face with regulation pressures concerning electric and electronic equipment waste and the various reactions of the actors responsible for recycling, the research develops two phases : the first, in Norway, provides a reading guide of the general context ; the second, in France, consists in a typical case study which involves many interacting actors and emphasizes the intermediary role of the provider. The results depend on the mobilization of skills in the field of thinking, organizing and relating to one another, and also imply the smooth implication of the stakeholders. These results should demonstrate that the logistics service provider who offers help in the field of global responsability can actually act as an intermediary in the context of sustainable development. Provided he or she takes into account all the parties involved and brings together the required abilities for coordinate management of the supply chain
