Texto completoProfessions connected with the exploitation of firewood and vegetable coal went through a period of intense development in brazil's nordeste at the beginning of the nineteen eightles. This phenomenon can be explained through the conjunction of that period : on the one hand, a drought which, from 1979 to 1983, imperiled the agro-pastoral economy of the semi-arid hinterland (the sertao); on the other hand, the increase of the price of hydrocarbons brought about by the second oil crisis. Lack of water almost completely destroyed local agriculture, making it thus necessary for the sertanejos to exploit the ultimate resources of the natural environment : the wood of the sparsely wooded forests of the hinterland. The production, first of firewood, then of vegetable coal, thus increased markedly, all the more so as the soaring prices of hydorcarbons compelled almost all the cement works and the mining concerns in the nordeste to replace oil by-products by ligneous fuel. This twofold exploitation of the work force and of the ecosystem), which is at the origin of the development of the professions linked with the exploitation of firewood, gradually lost its impetus with the return of rain in 1984-85. From 1986 onwards there began a period of shortage, particularly of coal, which hit the concerns which used it. Besides the resuming of traditional agro-pastoral activities, it illustrates the disengagement of the leaders of the sertao economy who, confronted with the disruption of the conditions of production, gradually gave up trading ligneous fuel. Beyond the strictly contingent aspect of this phenomenon, part of the working of the sertao society, its cumbersome structures and its relation-ship with the dominant areas of the brazilian coast are also revealed

Texto completoCurrent techniques for the detection and monitoring of droughts are based on meteorological networks. The small number of stations, often badly located makes these networks poorly representatives of the area they cover. The aim of this study is to evaluate the potential of satellite imagery for the detection, characterization and monitoring of drought conditions in Andalusia, in southern Spain. The satellite imagery used in this study comes from the NOAA 11 AVHRR sensor. Two indices (VCI and TCI) were calculated over 11 km2 areas centered over 11 meteorological stations. These were compared to the SPI, a widely used meteorological index. Correlation analysis between VCI, TCI and SPI show a good relation during drought periods and seem to support the use of satellite imagery for monitoring drought in the Mediterranean region.

Texto completoThe oualad rachid who number about twenty thousand people form a canton of djedaa, in chad. In fact, it is a sahelian agro-pastoral tribe which is constituted around bedwins. Separated from waves of arab immigrants who had accompanied the islam expansion in nubia, these nomads arrived in chad basin in the fourteenth century. Later. Autochtonal clans were aggregated with the ruling lineages. This was the case for bacara artisans who retained the power in this region before the arab's arrival. Consequently, at the beginning of the seventeenth century a true socio-political entity was born. Grouped in fractions, all its members finished by indentifying themselves, in their speech, with the eponyme ancestor rachid to whom each individual is linked by his genealogy. Faced with events which punctuate a man's life like, birth, marriage and death, they have taken up common attitudes, refering to the habits bequeathed by the ancestors. However, to survive in the context of insecurity which preceded the modern state's emergence, the group affronted foreing aggressions. It defended also its vital space, a sort of tribal territory or a country where rearing and agriculture became possible. This concept applies especially to the fields of cultivation. By another way, this notion is hardly deep-rooted in the ethnic groups of the chad centre which form sedentary stones between wich the oualad rachid pastoral people move. So, the pastoral mobility area of the chiefdom covers a region of more than 180,000 square kilometers from the 11th to the 16th parallels. But the borders of this space change from one year to another. The drought whitch began in 1968 has negative effects on the hydraulic and fodder resources, forcing the herds to move further and further south

Texto completoThis thesis aims at contributing to the description as just as possible of sedentary and nomadic populations'behaviour regarding land occupation and natural resources utilization in burem subdivision in mali. It describes the evolution of recent droughts, balances and imbalances between social systems and ecological ones. The methodology suitable to this study is based on : a bibliographic research, investigations near persons-resources ans civil service agents, and investigations near populations. The first part, dealing with an important bibliography presents the characteristics and the evolution of burem subdivision as regards natural milieus, land occupation, production and exchanges and local populations. The second and third parts describe the entire process related to investigations near sedentary population on one hand and near nomadic population on the other hand, sampling, questionnaires, investigations, data processing. The fourth part deepens six themes which are considered as important keys for development are for interatctions between man and natural resources

Texto completoThe nomads of north Mali a long time refused the policy of the colonial state then of the Malian state that considers the settling process as the basis of their integration and development. The current process results from two major facts that strongly affected the functioning and the structuration of social and economical life of nomads. It acts on the one hand, of the harmful effects of the dryness of 1984 and on the other hand, on the realization, following the intervention of NGO and the development projects, of many socio-economic infrastructures to accompany peace in an area weakened by the rebellion by the nineties. If settling process is justified by a socio-economic requirement, environmental reality constrains to the mobility maintenance, guarantees development of the breeding which remains still the system of production dominating and most viable. But, the priority of the socio-economic development compared to the environmental question puts doubtlessly risks for the future of the nomads. This future also will have to do facing the uncertainties of the recurring insecurity and the large building sites of development, in fact the dam of Taoussa as well as exploration and the possible oil exploitation
