Peres, Stéphanie. "La vigne et la ville : forme urbaine et usage des sols". Bordeaux 4, 2007. http://www.theses.fr/2007BOR40045.
Testo completoBecause exurban areas have outpaced urban and suburban areas in population growth for the last several decades, growth pressures are commonly observed at the rural-urban fringe, resulting in conversion of agricultural land for urban use. However the existence of a high quality vineyard questions traditional spatial structuring mechanisms. We must understand the role of vineyard on the morphological configuration of urbanization. The case of suburban Bordeaux vineyard, by its inclusion in both spaces at the heart of the Bordeaux metropolitan area, is ideal for the analysis of issues of interaction between urban growth and dynamic vineyard. The discret choice model associated with the duration model confirms the vineyard resistance, and also provides a means to inform the development of policies that aim at managing these pressures

Testo completoMICHEL, JOSEPH. "La qualite des previsions economiques avec applications aux previsions agricoles". Nantes, 1986. http://www.theses.fr/1986NANT4011.
Testo completoThis study aims at knowing the lessons of forecasting experience of the united states and france, for macroeconomic (part 1) and agricultural forecasts (part 2) part 1 as regards the united state the use of expert jugments seem to be a rather afficient method. For france some problems appear for several variables like investment, the balance of payments with econometric forecast. Futhermore, judgment play a significant part in econometric forecast : forecast assessment involves both the model and the cleverness of the model builder. Part 2 a comparison between forecasts and realizations is also carried out for agricultural forecasts. The same statement can be derived from the study of the agricultural forecasts. But : 1) instrumental models are efficient for forecasting prices 2) examination of past predictive performance tells : future markets are very reliable for generating forecasts about cereal prices evolution. 3) some examples indicate than rational and adaptative expectations have an impact on the forecast quality but are no essential for each variable

Testo completoThe conditions that are apt to generate the phenomena of sociability of social agents are a function of the relation of the forces that are sustained by the social context which governs the integration process, despite the sometimes contradictory character of the interests at stake within modernization projects. This assertion seems to explain the conditions under which agriculture is evolving in Africa. On account of the constraints associated with the technical development and unwieldiness of the politico-economic system, this sector experiences stagnation of its productivity today. In the specific case of Burundi, one of the reasons for this poor productivity have their basis in the increasingly long time-lags which cause a disconnect between the practices recommended by extension agents and the implementation of them by the acting subjects, in the event farmers. These distorsions, although minimized within official circles, have their basis in facts as thèse become manifested and or in the different, even contradictory, stakes of the social agents as the latter confront various strategies, policies, and methods of intervention within the peasant societies. On the basis of factual analyses, this study attempts on the one hand to clarify the question of technical dependence in relation to peasant submissiveness and, on the other hand, to open up a large debate on the essential questions associated with what should be the proper fit between the state's practices and the peasants'own strategies with a view to new perspectives of action
Guyomard, Hervé. "Investissement et choix technique du secteur agricole francais : étude économétrique". Rennes 1, 1988. http://www.theses.fr/1988REN11023.
Testo completoThis study investigates the structure of french agricultural technology using duality theory and flexible functional forms. The plan of the thesis is as follows. Part 1 discusses data analysis and measurement problems. Part 2 reviews the different generations of input demand models, while paying close attention to the invesment function. Part 3 presents our analysis of french agricultural technology using annual data from 1959 to 1984. TTwo approaches are followed to relax the assumption of full static equilibrium. First, since certain factors cannot be freely varied within the single period of observation, we develop a short-run hicksian equilibrium model : only the variable inputs adjust to their cost minimizing levels, while the quasi-fixed inputs remain fixed. We provide an exhaustive characterization of this model : more precisely, we discuss the underlying assumptions and show how the different possible equilibria can be derived from the knowledge of the short-run hicksian equilibrium. We propose also different possible measures of the disequilibrium, in the price space, in the inputs quantity space and in the output quantity space. Second, the adjusment cost hypothesis is invoked to specify and estimate a system of dynamic demand equations : a disequilibrium process is represented as a generalized partial adjustment model where disequilibrium in one input may affect other inputs

Testo completoSince 1962, Algeria has experienced strong population dynamics, which broke various balances economic, social and natural. One consequence of this population pressure is seen through the imbalance of agricultural resources, which led to an extremely high food dependency vis-à-vis other countries. Today, most of the commodity is imported and the gap between supply and demand is increasingly rising. Since the intensive exploitation of hydrocarbons, agriculture has often been neglected and relegated to second place. However, agricultural policy initiated by the country's independence ensured top performance in the agricultural sector, which enjoyed a reputation as an exporter sector mainly due to policies of basic infrastructures, , and of all sorts of supports as , a way of promoting very advanced techniques. How and why could farming reach such a state? What the State could do if the hydrocarbon resources are running low? How can the State put farming in the forefront? How can it give agriculture a place with which it will contribute to the economic development of the nation? How can it meet the challenges of the future and cope with population growth, climate change and depletion of natural resources, presently the almost only sources of finance for the State? To answer these questions, we first consider the history of the Algerian agriculture during the last centuries. This quest leads to the conclusion that a real farm policy, founded over a real and effective study of Algerian agricultural sector is necessary. To this end, a mathematical model linking together the main parameters of the Algerian agricultural system is built. Focused on the future of the sector in Algeria, its goal is not only to imitate behaviour of agricultural systems but also to produce scenarios that could occur in reality in case of policy changes it is based on a rational analysis of land use patterns as depicted in field studies

Testo completoThe objective of this thesis was to justify the performance of the ivorian agricultural industry (ag-industry) through out its market structure. The thesis used traditional and modern theory of industrial organization and linked them to ag-industry. The thesis shows that the ivorian ag-industry faces a quite paradoxal situation as far as economic efficiency is concerned this is due to the high level of protection and concentration. In other words, the agricultural and food sector did not benefit from profits earned from the existing market structure. Government intervention in all ag-industrial activities has created non-rational practices from an economic standpoint. This situation is due in part to community constraints which, in africa, are ranked number one priority in firm management
