Full textBefore colonization, the tribe was the entity of the territorial organisation in algeria. During the colonial era, the central state construction logic produces major changes regarding the territorial division and the power organisation. The tribe disappears and is replaced by the douar (part of the tribe) and the commune whereas the department is set up as relay between the local power and the central one. After independance, from 1962 up to 1967, modifications are progressively brought in to open up a new territorial restructuring and new attributions for local collectivities. From 1967 to 1974, major reforms are undertaken which create the wilaya (department) and enforce it as key-relay between the primary colletivity, the commune and the central structure. Despite the bipolary nature of the attributions of the system (an elected assembly and an executive council represented by the wali), the primacy of the state is made materialize through the preeminent power of the wali. In addition to the wali. In addition to the classical administration and management re local collectivities are given broad compectences in territory development and land use planning; they can act like real economic operators and create their own entreprises. In 1974, twelve wilayas are created. The development of thecountry. Industrialization, increases urbanisation and consequently makes denser the territorial organisation: five new wilayas are created and the number of communes is multiplied by three; almost in the one third of these communes(as far as the case of north-east algeria is concerned) the limits correspond to those of the douars. Throughout the last decade, this reappearance of the traditional susbstrata of algerian society goes together with the end of the central power primacy in the political context(apparition of multipartism) and the. .

Full textThis thesis is devoted to the study and analysis of local governance modes in Algeria. We seek from the territorial actors, acting at the level of a wilaya, to assess the mechanisms that govern the functioning of public institutions in charge of development in Algeria. The objective is to arrive at identifying the level where the articulation points are located between the expectations of local populations and different levels of decision-making, which correspond to the design and the elaboration of development programs. From a multidisciplinary approach (particularly the geography and economy) of the mechanisms of territorial governance and by the review of the current project design procedures, we tend to explain modalities of steering of development projects in Algeria and their command scales. The aim is to highlight the functional deficits in this area, and their impact on the quality of local development. A local development that can be called in our case economic development or urbanization. For this, we have chosen as field of investigation the territories of the wilaya in Northeastern Algeria: Annaba, headed the fourth largest city and an area with high economic potential where the chances of a local development remain considerable

Full textThe region of Annaba, situated in the North East of Algeria, contains in its underground water resources that represent a significant enough interest to feed people, water for agriculture and industry. This site is currently undergoing a gradual anthropogenic pressure becomes worrisome. Indeed, the continuous operation of the water has caused deterioration of water quality and negatively influenced the hydrodynamic equilibrium of the aquifer. It has also ensured the emergence of salt wedges even threatening in the short term and exploitation of the water and the proper functioning of wetlands.Based on the analytical results obtained for series of samples of more or less regular intervals, performed on the main measurement networks, we tried to identify key factors influencing the evolution of the physico-chemical water and delineate the advancing salt wedge. In this research, simulation models have proved to be very powerful tools to understand the hydrodynamic functioning of aquifers in the region of Annaba, situated north east of Algeria, taking into account the heterogeneity of environments. They have also highlighted a vulnerability of aquifers in coastal areas where there is inflow of the sea and stream chloride concentration large enough. The negative impacts on groundwater and ecosystems can become catastrophic if nothing is done to curb the problem.Models based on artificial neural networks have emerged as a powerful way to develop predictive relations between the different indicators of the management of water resources in the region. In this context of strong demand for water, only an integrated approach offers the possibility to manage these resources while respecting the natural environment, citizens' interests and those of economic actors. The research meets this need for integration, since the location and evaluation of groundwater resources, to protect their quality, but while evaluating the potential adverse effects. In this research, a new model of integrated management of water has been developed based on the relation of cause and effect addressing the entire cycle of water. Hydrological variables were developed and classified into five categories which are socio-economic constraints of pollution, water quality, impact of human activity and management of urban space and agriculture. The relevant variables were characterized using artificial neural networks, risk assessment on human health and the expert opinion. It has been demonstrated that a combination of practical measures necessary to ensure the sustainable management of water

Full textThe Algerian margin is a complex domain, limited to the south by the Maghrebian internal zones (AlKaPeCa) that overthrust the external Tellian zones southward. The offshore part of this system constitutes a back-arc basin, where a mio-pliocene sedimentary series were deposited over a substratum of laterally variable origin and nature. The goal of the present work consisted in analyzing and modelling the petroleum system at work and calculating hydrocarbon volumes. Before proceeding to different numerical basin, stratigraphic and thermal modelling, a conceptual geological model is required and was performed based on field geological studies and stratigraphic and structural interpretations of the seismic profiles. The extension of the continental crust beyond the foot of the margin, allows determining a chronostratigraphic model by extrapolation of the outcroping oligo-miocene formations onshore to the acoustic pre-messinian units defined in the offshore basin. Besides, a tectonic analysis in both onshore and offshore domains gave rise to three main steps of evolution: (1) syn-rift phase where the basin was opened by transtension since Late Oligocene- Aquitanian, (2) post-rift phase in which intra-arc basins were developed, AlKaPeCa and Africa docked and magmatism activity took place, (3) inversion phase where the margin became active mainly since Quaternary times. After defining the different petroleum system elements taking into account variable uncertainties, the 2D/3D petroleum system model depicts possibilities of oil and gas accumulations mainly close to the margin, between 20 to 65 km from the coastline to the north with a maximum range of 70 km in the Bejaia Gulf

Full textThe present study treats with the contamination by hydrocarbons, with superficial sediments of various stations repartee on two sites : the bay of Skikda (situated in the Mediterranean Sea) and the Saf-Saf oued (in its part downstream) with flows into this bay.This contamiation was studied by point of view geographical distribution, origin and nature of hydrocarbons extracts. The contents in found hydrocarbons are slightly more raised in the Saf-Saf oued (278 mg.kg-1sed. dry), that in the site sea (200 mg.kg-1 sed. dry). Compared with other studies made in the Mediterranean Sea, our results testify of an average level of contamination. The identification of the main origins of hydrocarbons presents in sediments of both sites, was made by using several indications relative to hydrocarbons saturated and in aromatic polycyclic hydrocarbons. The values of these indications allowd to highlight several origins for hydrocarbons as well in the Saf-Saf oued, as in Skikda bay (originate biogenic natural terristerial and/or marine, originate natural or oil pyrolytic and oil origins). A statistical study made the object of a second part of this work, by means of series of analysisesand of one-various tests (ANOVA, Tukey and Dunnett applied to periods, then to the stations for each of 5 characteristics), two-various (study of the correlations) and several-various (MANOVA, ACP and hierarchical analysis). These tests were applied to the data of both sites of studies and allowed to confirm the results obtained in the first part of the work

Full textWater scarcity is dealt with practically every day by the media, to manage it is a real challenge. The review of cases such as north west Algeria and south east Spain allowed for important findings to be reached. Population growth rate and the need for irrigation are the main reasons for increased demand. Water was managed in a sustainable way when demand was low. But since the beginning of the century, public authorities action focused in increasing the offer by every means. The management planing, shading away from its responsibilities, provoked shortages, waste, conflicts and deterioration. Consequently, public authorities are now promoting the liberalisation of water production and distribution. But water is not just a commodity, it is an essential element for life and a decisive factor of social cohesion. Market is not in favour of an ecologically and socially sound water management. Institutions are the guarantor of a sound and cautious usage of water and can modify behaviours in favour of a better management in a situation of scarcity. Ensuring the biosphere reproduction requires to be in conformity with it's renewal sequences and assimilation capacities. Mastering the hydrosystems, establishing water basins boards, impact studies, controlling waste and degradations, recycling and re-utilisation of water are tools which help to reach it. Taking into account the social dimension requires that basic needs are satisfied and to ensure equal development opportunities. To achieve this objective it is essential to have an accurate definition of utilisation rights and to offer the possibility for all actors to participate in the decision making process. A sustainable economic growth is necessary to obtain these results. The implementation of fees and subsidies, technical progress as well as setting up priorities would definitively help to reach these goals

Full textThis work is the result of an investigation of diachronic urban sociology, based primarily on the use of an ethnographic method. During the first phase of the investigation (1994-1996), I focused on juvenile sociability at work among the sons of Algerian immigrants in a neighborhood of an impoverished former industrial town in the North of France, in regard to their relationship to space, their experience of school, their conception of love and sexuality, and also to the consequences, for themselves and their close relations, of the entrance to an early and often long-term unemployment… The purpose of second phase (which took place during spring and summer 2010) was to understand which professional and marital strategies these post teenagers tried to build in order to escape the condition of grounded immigrants they had experienced fifteen years earlier as well as the influence, direct or indirect, of the previous generations. The issue of the access to adulthood reveals a much larger and a more complex issue which is that the access to age of man engages not only the isolated individual but the entire community, uncompressing its several generations
