Dos, Santos Cagarelho Nicolas. "Les droits français et européen à l'épreuve de l'innovation scientifique en matière agricole végétale". Thesis, Paris 2, 2016. http://www.theses.fr/2016PA020062.
Texto completoFrench agriculture, which perpetuated an after-war objective of established efficiency criteria, was guided by the search for a greater productivity. This direction, promoted by both the Common Agricultural Policy and the globalisation of the markets, was mostly driven by States with strong agricultural potentials, especially France playing a leading role. This evolution was guided by scientific and technology innovations, carried by three initial promoters: the public authorities, the agricultural sector and industrial groups. Scientific innovations, in an effort to protect the plants and improve the quality of vegetables, triggered a growing involvement of public authorities which faced alerts from environmental activists and increasing public opinion on the matter. The expansion of a national legislation has been followed up over the last twenty years by a growing European regulation. The latter aims at establishing a compromise between health and food safety as well as protecting the environment and industrial progress. It also questions the coherence of the existing legal framework for agricultural crops applied to the French territory, the current legislation on scientific innovations for plant agriculture and it's possible limits. This thesis deals with 'The French and European Law Facing Scientific Innovation for Plant Agriculture'

Texto completoIdentifying the environmental hot spots of agriculture is crucial in a context where humanity has to produce more food and pollute less. Life Cycle Assessment (LCA) is a powerful tool to evaluate the environmental impacts of agricultural systems, but is still fraught with shortcomings, notably for the evaluation of impacts of freshwater use and of salinisation of water and soil. The core complexity lies in the double status of water and soil resources in LCA which are both a resource and a compartment. The three questions answered by the thesis were: How to better assess the impacts associated with water and salts fluxes? What model should be developed for a relevant inventory of field water and salts fluxes? Is the developed model operational for an LCA study on a perennial crop? The first question was answered through a literature review on salinisation impacts in LCA. It revealed the main environmental mechanisms of salinisation, the factors involved, and discussed the soil and water status, notably through a consistent definition of the technosphere and ecosphere boundary. To answer the second question, a critical analysis of water inventory and agri-food LCA databases showed their inadequacy for the LCA-based ecodesign of cropping systems: they provide estimates of theoretical water consumed, rely on data and methods presenting limitations, and do not support the calculation of both consumptive and degradative water use impacts. For the LCA-based ecodesign of cropping systems, the inventory of water flows should be based on a model simulating evapotranspiration, deep percolation and runoff accounting for crop specificities, pedo-climatic conditions and agricultural managements. For herbaceous crops, the FAO Aquacrop model constitutes a relevant and operational model, but no dedicated model is available to-date for perennials. To fill this gap, a tailored and simple model, so called E.T., was elaborated for the inventory of field water and salt flows for annual and perennial crops. The model combines daily water and salts balances, accounting for soil, climate, agricultural practices and possible crop water and salinity stresses. A first testing of the E.T. model demonstrated its discriminating power for agricultural practices and its robustness. Its validity domain can be extended and its accuracy increased thanks to the recommendations provided. E.T. was also tested in the LCA of a Mandarin grown in Morocco. For most impact categories, electricity use for irrigation was the main contributor revealing a water-energy nexus. Water use had a major contribution to damages for all areas of protection. Overall, to further improve the assessment of impacts due to water use (including salinization impacts) we recommend using a more mechanistic and hydrological approach

Texto completoIn the absence of harmonization, Member States are authorized to prohibit or restrict the free movement of products presenting a risk to public health or to the environment such as drugs, GMOs, or plant protection products. To overcome this antagonism between freedom of movement and risk to public health or environment, the Community has followed different paths, often simultaneously : harmonization of conditions of risk assessment and issuance of national marketing authorizations, centralized authorization procedures at EU level, mutual recognition of national authorizations. This policy generally has succeeded in regard to drugs, and, to some extent, plant protection products. It is a failure in the case of GMOs, as many Member States refuse GM crops still authorised in their territory, in defiance of Community law

Texto completoFarming has always been a source of pollution for water. This link has been reinforced by establishing a common Agricultural control Policy in the EU. In fact the common Agricultural Policy is based on productivisme optiminzing the yield of land by using manure as well as fertilizers, polluting water to a High degree.However some reforms and a specific tax legislation have been created in order to reduce harmful effects on agriculture and on water ressources unfurtunately these legal and institutionnal instruments have proved ineffective.Therefore governements have sought to make farmers aware of there responsabilities with regards to pollution. Despite these efforts, the diffuse nature of water pollution has been obstacle to the implementation of such a regime agricultural pollution.Consequently goverments have no choice but to turn to more flexible instruments that allow polluters to be associated to the various mesasures taken to avoid the pollution of water, particurly by getting polluters involved in the procès and making them signe contracts

Texto completoIn the domain of vineyard precision spraying research, one of the most importantobjectives is to minimize the volume of phytosanitary products ejected bya sprayer in order to be more environmentally respectful with more effectivevine leaf treatments. Unfortunaltely, even if lot of works have been carriedout at a parcel scale, mainly on losses caused by drift, less works have beencarried out at the leaf scale in order to understand which parameters influencethe spray quality. Since few years, recent improvements in image processing,sensitivity of imaging systems and cost reduction have increased the interestof high-speed imaging techniques. Analyzing the behavior of droplets afterimpact with the leaf thanks to high speed imaging technology is a relevantsolution. By this way, we propose a droplets behavior analyzing process invineyard spraying context based on high-speed acquision system combinedwith image processing techniques. This process allows us to extract dropletsparameters. Therefore, a statistical study is processed in order to determinethe effects of droplets parameters on leaf impact or to predict behavior of asingle droplet. Since this behavior is strongly related to leaf surface, we alsopropose to validate a natural leaf roughness characterization method basedon texture analysis

Texto completoPlant protection products, also known as pesticides, are used to fight against offensive organisms on plants. By doing so, they also guarantee crop yield and food supplying. French legal framework has been genuinely built to ensure market efficiency to these products even before trying to limit their impact on health and environment. With the community thematic strategy on sustainable use of pesticides, its objective gets more aspiring as it now concerns the reduction of farming dependency on pesticides. But more than reducing the use of these products, it becomes necessary to implement new practices. Moreover, new agronomical methods have to be set up against pest emergence and its uncontrolled growth. Although market rules on plant protection products, which are in the core of the legal package, do lower the risk on health and environment, they hardly reach this goal. It is the same analysis with the yet promising legal framework on pesticides use. Calling on the entire resources of agricultural law becomes necessary in order to redirect farming practises. In spite of the help from both market instruments and the very structuring framework of the common agricultural policy, the growing integration of health and environmental concern stays at an unsufficient level to substantially change these practices

Texto completoAgricultural soils provide many ecosystem services (ES) to farmers and Society such as green and blue water provision, nutrient provision to crops, water quality regulation, carbon sequestration etc. However, most cropping systems are still intensively managed, based on chemical inputs, with little to no consideration of the possible effects of such practices on the environment and the ability of soils to provide these ES. One issue of agroecological transition is to design more sustainable production systems, with limited use of chemical inputs, that provide and benefit from biodiversity and the ES support of agricultural production. We thus need to improve our knowledge on the spatio-temporal relationships that may exist between management practices, agricultural production, ES and environmental impacts. This manuscript synthesizes the results of a three years INRAE-ANDRA collaboration that aimed at providing key information on soil-crop functioning while facing this challenge. This work was structured into two parts. We first conducted a systematic literature review of the relationships between agricultural production, the ES and the impacts linked to soil functioning, within temperate annual production systems. In order to be able to compare the results of the 40 studies selected, we developed a new ontology of soil-based ES and impacts. This review evidenced mainly non-significant relationships between Biomass production and the ES and impacts investigated suggesting that there is no systematic trade-off between agricultural production and regulating ES. We also identified key relationships that have never been investigated in the studies selected as those between C sequestration and Physical soil quality regulation or Soil biodiversity. Also, an analysis of the effects of drivers of these ES revealed that the three pillars of conservation agriculture, as well as organic fertilization, seem promising practices to provide balanced bundles of ES. We then performed simulation analyses of actual and agroecological cropping systems of the French long-term Environmental Observatory of ANDRA. The objectives were to assess the effects of more N self-sufficient cropping systems, with a climate change mitigation purpose, on the temporal relationships between agricultural production, 5 ES and 3 impacts linked to soil functioning. These cropping systems were designed by implementing three agroecological management practices: a) long cover crops with legume (crimson clover), b) grain legumes (pea) and c) fodder legumes (alfalfa). To assess the performances of these systems, we used the STICS model, that simulates the functioning of the soil-crop system at a daily time-step. Simulations were run over two 20-years time periods: a first one for recent past climate (2000-2021) and a second one for future climate projection using RCP 8.5 (2036-2057). If most of the temporal relationships analysed were non-significant, results highlighted that the use of long cover crops in the rotation provided the highest values of N provision to crops and C sequestration and the lowest values of NO3 lixiviation
Le, Bars Maureen. "Devenir du zinc des produits résiduaires organiques après méthanisation et recyclage agricole : rôle des nanoparticules de sulfure de zinc". Electronic Thesis or Diss., Aix-Marseille, 2019. http://www.theses.fr/2019AIXM0034.
Texto completoAgricultural recycling of organic waste (OW), raw or after a treatment like anaerobic digestion (AD) and/or composting is common. It is necessary to assess the environmental impact of OW agricultural recycling after anaerobic digestion since this technology is gaining interest, particularly regarding zinc, an abundant element in OW. In order to properly evaluate the risk, zinc speciation must be known. First, we have shown that AD promote the formation of nano-ZnS that is therefore the main species of Zn (> 70%) in AD digestates. This unstable species is transformed during composting of 1 to 3 months. Size and strain are parameters that can explain nanocrystals reactivity. We showed that the more nano-ZnS are small and the higher the strain is. Interaction with thiol containing organic molecules, potentially present in anaerobic digesters, release nano-ZnS structural strain and control its growth. Finally, amended soil characteristics have a key role for nano-ZnS fate: the components of clayey and iron-oxide-rich soils are able to immobilize Zn released by nano-ZnS dissolution, unlike sandy soils components. This work gives a better understanding of zinc dynamics in cultivated ecosystems subject to spreading of organic waste
