Full textStrongly marked by a mediterrenean climate with a tendency to aridity the Hodna has inherited from a pastoral society imbued with nomadic traditions. This has engenalered an organization of its area founded on the complementarity of different environments. This complementarity is linked with a constant movement of populations and herds, so, and movements of variable importance. The climati's aridity points on the weakness of precipitations on the nain part of the versant bassin. The chain of the Hodna stands as a barrier to the atmospheric disturbances coming from north. It constitues the southern limit to mediterranean influences. This situation is often aggraved by a high evapotranspiration a low vegetal cover favoring erosion. Climati's aridity does not necessarily mean absence of water, for the Hodna's inhabitants have practiced for a long time an irrigation which was based on flanned inundation, it attest for the absence of flow. Although the precipitations are weak, they fall down in the form of showers rendering the flows into swelling. Oueds, that are supplied by numerous springs, rising at the bottom of mountains, have brought not inconsiderable contributions. The following paradox : arid climate-abundance of water, is confirmed by the large potentialities of subterranean waters presented by the set up aquiferous. The improvement of hydraulic situation is most possible. It lies in the recovery of rain waters thanks to process of retain and to rational exploitation of subterranean waters so as to hope finally for an integrated development of the Hodna

Full textRecent literature on poverty alleviation policies has focused on one direction of discourse by considering poverty as a depending variable based on income or expenditures. Results have not been satisfactory so far. The importance of factors other than income in determining living conditions such as education, gender, water and characteristics inherent to society, can contribute greatly in explaining the acuteness of poverty. The aim of this thesis is to quantify the subjective poverty of Algerian households by taking into consideration one of the last factors namely water domestic characteristics as the direct focus. We attempt to apply the ROC(Receiver Operating Characteristic) to determine the true poor household through the water factor. This method has the advantage of eliminating the poverty line which is based on monetary factors. To do that, we proceed with a field survey on a sample of 786 households in the wilaya of Tlemcen. A classification is made according to the unidimensional approach (monetary) and hydraulic characteristics of the poor households. The results shows the indicators which characterize the true subjective poor households , like the type of access to water, the arrival frequency of water in the household, the means of water storage. . . These results make a good opportunity for policy makers to have a best targeting for households which require a help to reduce the phenomenon of poverty

Full textThe Zibans area situated at the foot of the mountains which stretch from ine side of Biskra to the other, forms a pre-saharian region. In the north of the Bas-sahara, the Zibans region is made up of Piedmont oasises. Structurally speaking, this region represents a contact between two morpho-structural domains which are clearly different : the Sahara Atlas and the Sahara. The climate of the region is influenced by a mediterranean-like half-orren climate, which prevails over the high and the influences of the desert climate of the Sahara. Favoured by its position at the foot of the "Atlasic" relieves this region is an exception is the Bas-sahara, for it uses both surface water and subterranean water. These physical factors explain the clear opposition in the geographical distribution of the palm groves between the eastern ZAB CHERGUI and the western ZAB GHEBI

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 problem of water is really acute in all the Algerian cities that is why the theme about the supply of potable water for the city of Constantine has been chose. For this it was necessary to introduce Constantine taking into account its climate, its relief and history, to come afterward to the inventory of the situation of the different underground reserves because of the lack of water, and the unsteady relief of the town, the distribution of water is undertaken with difficulty: one day out of two, during 2 hours maximum, without forgetting the problem faced by high buildings. The norms stated by the OMS (world health organization) are 1501 inhabitant day, are far from being reached and after the study of some statistics, it has been estimated that Constantine will always face supply difficulties and remains dependant on the discovery of new springs the system of making water healthier, which seems to be satisfactory, is divised into three categories: unitary, separatist and inexistent. Spoilt water will be collected and treated by the future purification station in order to irrigate the agricultural fields of hamma. This will allow Constantine to benefit from an appreciable volume of potable water

Full textThe city of Tamanrasset as a new city in the central Sahara was faced throughout its history to a water supply problem. This situation endures the population of the city had a rapid population growth (settlement, immigration), uncontrolled urbanization and limits water resources. With the persistence of the shortage, lack of access to safe drinking water, and inefficient state management, people have always used the services of water reseller’s tankers, and developed storage devices more or less sophisticated to ensure regular consumption in within the housing, while being independent of rotation program distribution developed by the ADE. To solve the problem of shortage of water, it took the intervention of the Algerian state by carrying out a large supply project by transferring fossil water (Albian) of the down Sahara to the city of Tamanrasset (700 km). It should be noted that the passage of a management shortage to abundance that remains a challenge requiring more resources and attention. More specifically speaking, the work we've done for the interactions between the rationing imposed by the water services in the city as a result of lack of water and inadequate management policy, with specific local and the solutions envisaged by users and the state

Full textThe recent period of dryness in maghreb (1981-1986) attracted the attention on the rarety of water. Indispensable element to life, water is a factor limitating a country's development. So, algiers like many other mediterranean cities, is submitted to physical natural constraints characterized by interseasonal and interannual climatic variations (600 mm annual precipitations) which have consequences upon exploitable resources and, therefore, water distribution of the 2 millions citizens. The algiers's growth increases its water needs and the result is an inadequacy between the supply and demand. The water shortage, in the past arusing out, became structural. The research is divided in 3 parts. The first part (105 p) concerns the mobilization of the water resources and the distribution, the administration of the drinkable water. The absence of local water resources makes algiers a dependant zone for its supplying water of its hinterland and of the border areas. The second part (119 p), by using the available statistics, analyses the water consumption in algiers and the problem of competition for the use of water in the region. The theme of unequal distribution of water in the urban space is also treated, a theme which is more widely analysed in the third part (84 p). The survey of the consumption habits of water is realized from an inquiry upon 93 women living in 3 different parts of algiers (hydra, belfort, casbah). The purpose of this survey is to show how the households absorb water in their daily life, the consequences of water rationing and the fundamental role of women in the daily administration of water

Full textThe Analysis of the sustainable management of water resources in Niger area reveals that the development of its contemporary water law and strategies are influenced by western legal models and water policies. Before the domination of occidental models, customary mechanisms and traditional techniques belonging to water resources management allowed sustainable use of these last ones. They still enjoy the social legitimacy and are widely applied in rural areas through all Africa. This situation involves the phenomenon of legal pluralism, because the African States, in particular French-speaking, immortalized the western legal models, instead of conceiving strategies adapted to local realities. This paradoxical situation puts not only difficulties of management for national waters and shared basins in particular Niger River and Chad Lake, but also the challenge of the effectiveness of human right for the drinking water. Indeed, national and regional water laws, basin commissions set up after African independence do not answer the requirements of sustainable, integrated water resource management for the benefit of present and future generations. Answering these incapacities and constraints implies that cultural dimensions, local knowledge in water or environment sector have to be recognized and valued by international, regional and national actions. This perspective will facilitate the elaboration of regulations adapted to local preoccupations, the consolidation of shared water committees, and the implementation of participative strategies and contribute for the durability of actions for management of water resource in Niger area

Full textBiskra and Ouargla are two sub-units which are home of the Bas-Sahara, where the economy and the population are soaring. They are characterized by the coexistence of two forms of agricultural production in different ways and factors of production available, one capitalist and another one traditional and suburban. The traditional form is facing a difficult, economic, social, hydrological and agricultural reality. Its current operation is subject to secular’s peasant’s rules and methods, but has difficulty to the two speeds socio-economic change. The management of agricultural space in the two sub-assemblies can not be dissociated from the regional or local level, because natural resources are unevenly distributed. The rural population is made up of family and composed. Agricultural land is a fundamental element of their attachment to their space. Its operation is subject to specific methods of a sahara’s peasant. The management of water as a valuable natural resource in such an area is subject to rules and methods based on equity, solidarity and discipline. The external links of this space are first based, on the relationship between themselves as producers, the market for the marketing and supply, market and professional bodies. Relations peasant-farmer, farmers' market and farm-workers are much stronger than that maintained with the State, as a player in the functioning of this area consists mainly of intensive and often aging, especially in Ouargla. These farms are not immune to the biotic and abiotic threats, which jeopardizes their sustainability over time, although some farmers show their determination to go far in their investment and their expansion, if conditions are favorable. This determination leaves some hope for the traditional survive longer

Full textIn this work, we propose a thorough analysis of the residential water demand in Algeria. The first chapter presents the main issues regarding water management in Algeria. Then, chapter two reviews the extant literature in order to identifu the current research trends in this field. In the third chapter, we estimage the demand function or residential water demand using three databases (aggregated date, individual data from 27363 subscribers observed over 17 aurters and a sample of 172 customers observed over a period of 45 quarters). These estimates indicate that subscribers of the wilaya of Jejaia are a little sensitive to price changes (price elasticities range from -0,14 to - 0,67). The results also show that the price elasticity is partly constrainted by the esimation period and the nature of the date used. To complement our analysis, we analysed in chapter four, the impact of rising prices and policy restrictions on the welfare of households. This analysis tells us that one hour of restriction is equivalent to a price increase of 10 %. We also analysed the factors responsible for the duration of paument of household bills. This analysis reveals that some of the delays can be explained by economic factors such as income and prices but ut also seems that the discontent of subscriberts with the water service quality explains actual delays. To confirm this result, we considered in the last section, the willingness to pay of customers to improve water service quality. Our estimates show that 99,4% of our sample accepts to pay more to improve the water service quality. The estimated willingness to pay indicates that local subscribers are willing to pay 10,57 DA/m3 more for a better water service

Full textThe Malekets jurisconsults define the good building as understood: the ground, the buildings on the ground and the intrinsic capacity of knowing, in the first place, the water that constitutes an essential element. The French Protectorate instituted a "bicephalic" system to know the side of the registered estates in which there are non registered estates submitted to the Malikite rite and others submitted to a special statute instituted by the "Makhzenian" system; especially the "Elguich" grounds or the collective lands. Thus, the judicial regime of water stopped the submission to the Malikite rite -Muslim's law- and to local customs contained in the doctrines of "Souss", Fez and Marrakech. These dispositions served in palliating the statute's gaps of the registered estates in which there was no anticipation of specific dispositions. The jurisprudence collided with the problem of applied law: was it the Malikite rite? The local customs? The answer shall be different according to what we refer to as this or that legal statute. Instead of intervening in the separation of the jurisprudence, the legislator has intervened in the opposite sense, that is; the consecration of different without resolving it so as to keep a specific water regime which is derived from the registered buildings, but for the others, he did not resolve the disagreement. Concerning this subject, we can raise several problematic; among which we cite: what are the points of convergence and divergence of different legal sources? Does the tripartite aspect of legal sources permit better exploitation of the estate's ownership technology in Morocco?

Full textAt the scale of a city, a sustainable water management raises questions about the links between uses and resources: what water quality is needed for what purpose? The Parisian context is a favourable ground for conducting such type of reflection thanks to the existence of a non-potable water network (RENP) dating from the late nineteenth century. The network is currently supplied by summarily filtrated water from the Seine river (20%) and the canal de l’Ourcql (80%). It is mainly used for municipal purposes: Parisian streets and sewers cleaning, water supply of artificial lakes and green areas watering. An alternative model of water management at Parisian scale is today possible thanks to the decision of the City of Paris in March 2012 to maintain and rehabilitate its RENP. This decision has been confirmed by the approval by the Council of Paris in September 2015 of the master plan of the RENP and its uses (“Schéma directeur des usages et du réseau d’eau non potable de Paris”) for the period of 2015-2020. The public company Eau de Paris, responsible for the water service in Paris, is mandated to implement the decisions and orientations of the master plan. In the context of pressure reduction on natural resources, one potential evolution of the RENP management is its resources diversification. The considered potential resources are mine water, treated wastewater, rain water and swimming pool water. The research raises the following question: How and under what conditions can the RENP supply be sustainably managed on the Parisian territory? In order to answer this question, one first carries out a description of the current situation, then one identifies the potential resources and the associated risen questions. Two approaches are proposed afterwards. The first approach involves the definition of several choices of RENP resource repartition, called scenarii. These scenarii are assessed and compared through performance indicators. The second approach consists of the characterization of the actors’ positions regarding the RENP resource diversification. The characterization of the positions is achieved through conducting semi-structured interviews. Results of both approaches are finally discussed.The results of the research will enable to re-examine the question of the relationship between the water uses and the required water quality. It will highlight the brakes and levers for the valorization of alternative resources to drinking water. It will enrich the reflections on the status of drinking water in the context of sustainable water management

Full textAfter its independence, Algeria was confronted with a situation of very advanced degradation characterized by a significant regression of plant place setting an intensification of the erosive phenomena of the mountainous zones and the appearance of the landscapes become depopulated in the steppe. This situation is the outcome of a set of historic and natural factors. Considering the vital importance of the national heritage and its biological variety, Algeria leads a steady policy of development of the forest sector which was characterized through the various national plans and special programs. This thesis suggests detecting the elements which made failed this policy, to plan to recommend better one management of the Algerian forest and to determine the existing links between natural resources, rural population and development policy. A series of qualitative investigations on the basis of a guide of interview was made with the agents who participate in the elaboration of the forest politics and its implementation and the rural population to be able to loosen the failures connected to this last one. This present document redraws the product in which we ended in the term of our work on the ground, however and after a presentation of the frame and our problem, said document includes three essential parts: situation of the forest sector in Algeria, situation of the forest sector in Algeria, the Program of Rural Employment for the long-lasting management of the resources

Full text[The objective of this thesis is to define and to participate m the development of a tool aiding in the organisation of both the production and the distribution of drinking water during normal or unusual periods. This study has been mainly centralized on the check point control of the pumping and stocking of the drinking water distribution network of LYON and its near suburbs. The realization of such a tool is complex and requires to organise the conception process. The strategy aims to quantify the current unsatisfied actions by analysing, the possible gap between the goal obtained and the wished one. We can deduct from this analysis an overall solutions aiming at improving the existing system or to enriching it. ]

Full textConflicts on freshwater resources will increase in the 21st century. Such conflicts, based on claims of absolute State sovereignty, can be prevented and controlled by international law. For this purpose, this thesis presents the concept of solidarity which can be realised in two ways : by a broad internationalization of the object of international freshwater resources law and by sharing competences between the subjects of this law. A tendency for spatial expansion of the object is becoming manifest. Starting from the international rivers, current international law deals with larger approaches, such as the riverbasin or the transnational hydrographical system. These approaches can be extended to the management of the hydrosphere which ignores borders and includes internationalized spaces. Legal freshwater management, initially limited to quantitative and qualitative aspects, has to integrate issues such as economic development, international security and theoretical aspects of international law. The sovereignty of a State is limited by other subjects of international law. Obligations between States are becoming more concrete, especially thanks to the recent conventions on the law of the uses of international watercourses. Inter-, para- and infra-State bodies dispossess States of a part of their sovereignty. A paradigrn change results from the emergence of competences of individuals, their groups and humankind

Full textThis work deals with the factors of flow and the hydrologic characteristics of the Oued of Nekor which aim is the planification of waker resources. The task of the management is very difficult, in that the physiographic and climatic conditions are very unfavorable: - the problem of the filling of mud of the reservoir of the weir. - the fast return back of the dry years of rain the great irregularity of the flow the Oued of Nekor shows how pressed are the margins of the management. The risings from the half of the drifting of the Oued of Nekor, whereas some of them must be evacuated in order to avoid the rapid raising of mud in the reservoir of Mohamed Ben Abdelkrim Elkhattabi's weir
