Jackowska, Jonathan. "De l’eau et des idéaux. Les formes d’engagement des organisations de la société civile à l’ère de la gouvernance de l’eau au Sahel. Pistes de réflexion dans le domaine de l’accès à l’eau potable." Thesis, Paris 4, 2011. http://www.theses.fr/2011PA040049.
Full textThe participation of non-state actors (e.g., civil society organizations, private companies) in the management of public affairs is one of the major characteristics of governance. In its contemporary meaning, this notion implies a redefinition of the role of the State and invites to the delegation of public utilities. It leads to the promotion of the lucrative and non profit-making private sector. In the field of access to drinking water in Sahel, numerous civil society organizations (CSOs) dedicate themselves to the provision of services, carrying out social missions which fell previously within the State prerogatives’. Most CSOs follow the structural reforms (e.g., pricing, private sector participation) which have been introduce for the past twenty years in hydraulics, both in the urban and rural areas. On the contrary, some CSOs dispute the current structural changes through the denunciation of the « commodification » of water as well as the « privatization » of water supply utilities that favour large transnational private operators. They denounce certain CSOs that would contribute, through their actions, to the inculcation and to the validation of principles promoted by the reforms. The plurality of the representations of water, the variety of the promoted modes of water management : these different points of view which feed the public controversies, the oppositions – but sometimes arouse the mergers – between CSOs, private companies, States and institutional sponsors are in the heart of our thesis. The inter-association relations are also considered. If problems are often perceived from a similar point of view and necessity to reform widely acknowledged, important differences lay between actors when considering the solutions to propose and the type of reforms to implement

Full textTunisia, the country from which sparked the revolutionary uprising in December 2010, presents a political and economic situation that has continued to evolve in a direction that is not always positive. It is characterized by instability and sometimes anarchy, which has had repercussions in all areas, particularly in the vital area of water, which management has been severely disrupted.In this perspective, this resarch is intended, based on a series of surveys and interviews, to contribute to a better understanding of the risks of water scarcity for the various actors in charge of the management of the resource in the area of the Tunisian Sahel (Sousse-Monastir). It proposes a critical analysis of the different interactions between the factors of scarcity and the indicators of water crisis in connection with the socioeconomic and geopolitical situation. The results of these investigations show a very delicate situation especially after the Revolution. However, levels of scarcity vary from one county to another eventhough the feeling of water stress is widespread in the tunisian Sahel. The study also offers a spacialized dataset that can be integrated into a Geographic Information System (GIS), as well as a battery of individual and collective adaptation measures for a more efficient water management based on taking into account perceptions

Full textLong queues, buckets, yellow canisters, women and children talking around water fountains. From here starts the unending back and forth of the water carriers, using rickshaws, animal powered carts or eventually walking. This sight which has disappeared elsewhere and reminds the urban history of rich countries such as France, is everyday life for the dwellers of Sahelian cities. Niamey, Niger’s capital city, located in the heart of the Sahel region, is the country’s most important urban area. The access to public service water is characterized by a socio-spatial fragmentation consequence of a faster spatial extension than the extension of the network which is timidly growing year after year. In many districts, mainly in those having a peripheral location regarding infrastructures (factories, reservoirs), the access is also marked by socio-temporal discontinuities. They come from an urbanization of poverty, quick and badly initiated for more than 50 years. To that, one needs to add a hot and arid natural environment, competing with the anthropogenic need for the control of water resources. From then on, the fragmentation of the access to water has been unprecedented, enlarging even more the gap between the ones who are connected to the network and the ones who are not. These forgotten ones manage to satisfy their need for water using alternative services derived from the network and the ones who are autonomous manage using drillings or mini-networks. This huge amount of water services coming from individual or collective initiatives in Niamey allow a hybrid access to water for the citizens. Without this contribution, the hydric balance at the scale of the city wouldn’t be reached during heatwaves where, whether connected to the network or not , the quest for water requires imagination and know-how from the families. So, beyond this situation of hydric uncertainty described by this thesis at the scale of habitat and town, it also tries to detect the different socio-economical and socio-technical structural factors which make better access to water a problem. To understand these factors so as to put them into perspective in a space lay-our proposition of the point of access to water is a proof of the reduction of the effects which weigh heavily on the availability of water in the Sahel such as heat and poverty. In fine, conciliating uncontrolled urbanization and a lasting offer of water services, spatially and socially adapted seems to be an answer to these Sahelian urban challenges given by the example of Niamey

Full textThe objet of the study is related to the research on a coviability between humans and ecosystems within a sahelian context whose environmental, socioeconomical and political data have deeply evolued since at least twenty years. An approach based on the anthropo-juridical study of the various exploitation systems and their interactions infers the fundamental imbrication of the land (defined as the substrate support of the biotic elements and the ecological process) and of the environment (composed in particular of the renewed resources as stakes of power relations). This approach in environmental law is made from a methodological attitude taking into account three observation scales : the village territory, the province and the region. Constituing the binomial spaceresource as unit of observation and as operative concept in every scales, it explores the relation man-natural environment by decorticating the land tenure frame of each of the exploitation systems taken individually and in interaction with the others. The aim is to think the principles of a right considering the interactions which weigh on the behaviour of individuals, on their decision and their action in terms of management of natural resources and which integrate the necessity of the longterme coviability of the biodiversity and of the cultural diversity. This right should constitute a change lever and allow to move from the conflicting and disorganized situation that the analysis of the social structures shows to a juridical situation where the liberty margin of the social actors and their respective responsability shares are clarified in accordance with the rights they have on the space-resources and in which they must be, in other respects, secured

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 textIn semiarid sub-Saharan Africa, the rapid population growth (~3%.yr-1) during the past few decades has resulted in land clearing and large-scale conversion from savannah and fallow to rainfed or irrigation crop fields. The traditional duration of fallow has been also shortened. In order to estimate the impact of these land use changes on groundwater recharge, the vadose zone was investigated during three years (2009-2011) for two regions located in Niger (south-west and south-east).A qualitative analysis was first carried out for identifying vadose zone properties and for characterizing the corresponding water fluxes (0-10 m depth) for the main land use types: natural savannah; fallow; rainfed millet crop; and irrigated sweet pepper crop. Grain size and electrical resistivity profiles were established and soil water content and matric potential were monitored. Based on the results of this analysis, two more detailed investigations were performed.In southwestern Niger, in order to estimate changes in diffuse recharge from a fallow with Guiera senegalensis to a rainfed millet crop (Pennisetum sp.), a physically-based modeling with Hydrus-1D code was completed. Probability density functions were first built for the soil hydraulic parameters based on the GLUE approach; then, deep drainage (0-10 m depth) was simulated for a 2 × 100 year time-period including a fallow-millet conversion. It was shown that the increase in millet crop areas could result in an increase in deep drainage from 20 to 25 mm.yr-1 after a delay of 35 to 60 years.In southeastern Niger, in order to assess the impact of rainfed and irrigated cropping development on soil and groundwater salinization, major ion concentrations in pore water of the vadose zone were measured and compared with the geochemical composition of water inputs (rainfall, irrigation). It was shown that rainfed cropping does not affect soil water and groundwater quality whereas irrigation results in an increase of solutes concentrations in soil pore water, which could lead to a groundwater salinization at mid-term through soil leaching

Full textThe Rural District of Thieul, located in the South Sahel component of the Senegalese Ferlo Natural Region, is south enclosed by the Peanut area. In addition to the repeated climatic crises in the Sahel countries (droughts), these are new socio-economic and demographic pressures, negative political and institutional tendencies on Productive Natural Resources with land tenure crisis. These are all factors that can lead to uncertainties, vulnerability and poverty if there are no reactions. Therefore, dealing with this new environmental production context, characterised by Productive Natural Resource Rarefaction, the Agro-pastoral Farmers of The Thieul Rural Community has developed new strategies, based on also material and immaterial Capitals implementation in channel production. Strategies are also based on capacity building and capabilities that permit diversification in family production activities, innovations for sustainable rural livelihoods

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 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 textWater and waste management are complex and changing. Integrative management seems to be an ideal solution for many. However we think that, more than a solution, it represents the symptom of a management crisis. In order to tackle this crisis and to introduce some integration, new arrangements between actors and new management tools are elaborated. On the one hand, we see Integrative collective action as a combination of exploration and prescription cycles concerning both knowledge and relation. On the other hand, integration models are made of combination of arrangements between actors and management tools. We maintain that : - each integration’s model takes part in integrative collective action. Nevertheless, no model is perfect. - the model of integration built in this doctoral thesis at a departmental level is not perfect but it works. We analysed the action of the departmental Council in water management in order to illustrate our theory. We used the example of an actor : the Bas-Rhin Council ; and the implementation of a new management tool : a water observatory, which was our field study

Full textThe characterisation of water is strongly related to the functions and services delivered by the water. Nevertheless, a consensual approach relies on the fact that “the water is not a private good as the others”. Therefore the analysis of the natural capital ‘water’ challenges the standard economic approaches. The market mechanisms are not efficient for goods that are non exclusive and non rival. Environmental governance issues are characterised by uncertainty and complexity often embedded in incomplete information. In the context of the sustainable development which supports to reconcile the economic, social and environmental dimensions, one major challenge is the public participation in the water policy. Non expert knowledge should enhance scientific knowledge for two main reasons: in order to complete the information as well as to raise the social acceptability of water management measures. Our research explored how deliberative approach organised with virtual tools support the economic evaluation for water sustainable management. We showed multi-criteria analysis is complementary to cost benefit and cost effective analysis, highlighting their capacities to mobilise and structure different kind of knowledge. The first version of the Deliberation Matrix has been developed for our case study: Champigny aquifer. The concept is embedded in a multi-criteria and multi-actors analysis structured with governance issues and potential futures of the aquifer. The transposition of the concept to the deliberation tool Champigny DST answers some of the Science Society Interface challenges

Full textMykonos's, Delos's and Rhenia's (Cyclades, Greece) physical environment isn't really favourable to set up plentiful water resources. Groundwater are supplied by irregular and slight rain and their volume is limited by the small size of watershed and by crystalline basement. This environmental conditions, which probably did exist during the antiquity, didn't stop the quick development of a city in the second century BC in Delos. This expansion needed the construction of wells, cisterns and "infiltration wells". The aim of this research is to better understand hydrological dynamics of this island and his interactions with hellenistic hydraulic facilities. A climatic, geomorphologic and hydrologic study of the present environmental conditions is crossed with archaeologic and historic data. This work allowed to hypothesize how water was managed during antiquity

Full textThe senegal river, 1. 750 km long, a kind of oasis in the center of the sahel countries, opens into the delta at its wostern limit. This delta, having an overall area of 400 km, is a mass of low lands, with no apparent relief, covered by an anastomotic network of defluents. The sea, by its transgressions and regressions the wind and the river are the cause of this delta region. The sahel climate, consistingu of txo dry and rainy seasons is hot (30 on average) and damp (hygrometry : 70 % on average). The delta is inhabited by several traditional natives (56 % woloff, 26 % peulhs, 10 % maures) and newcomers ( 8 %, toucouleurs, serere, soninke, diola, etc. . ) through a state-derived regime, the land is classified into four categories (urbain areas, racial areas, famers and pioneers). However, water ressources are as follows : rain water (annual average 280 mm), underground water (untapped, 5 g l salinity), and espacially surface water from the river the flow of which is 2,480 m s on average and which feeds several reserves including gorom-lampsar and lake guiers to supply the population of st-louis (80,000 inhabitants in 1982), dakar (1,000,000 inhabitants), surrounding population (60 938 inhabitants), hydro-agricultural management (20,000 ha), livestock (330 000 heads), djoudj park and other classified natural areas. .

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 textWater markets have been suggested by the literature as potential tools to manage water demand in a context of water scarcity. They are meant to improve water use efficiency while offering water users additional risk management strategies and can be used to redirect water towards the environment. While the theoretical literature dedicated to water markets is plethoric, the empirical aspect has long been neglected, often because of the limited number of available case studies and data paucity. This empirical thesis dissertation focuses on one particular case: the Australian water markets, which are among the most advanced water markets in the world. Four general themes are discussed: economic impacts of water markets in Australia (Chapter 1), potential market failures and particularly insider trading (Chapter 2), their functioning in practice (Chapter 3) and considerations related to the adoption of such systems in France (Chapter 4). Without any pretentions to exhaustivity, the objective of this thesis is to improve our knowledge on these potential water management tools
