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 textIf Tunisia, as well as all the other similar countries, wants to avoid, or at least to postpone the mobilization of non conventional water (desalinization, virtual water, etc.) with sensibly higher costs, the only alternative is to rely on appropriate water demand management. Water pricing must be considered seriously as a useful tool, with certainly the other non price instruments, such as awareness, education, water conservation and participatory management, to keep under control the demand evolution. In this thesis, we use Tunisian data and a decomposition into two water consumption blocks to estimate residential water demand function. Firstly, seasonal investigations show that Tunisian water pricing policy was not perfect. The lower block’s consumers are most affected by water tariff progressivity than upper block’s consumers. The seasonal fluctuations and the alternation of rainy and dry seasons affect only lower block’s consumers. We then advocate increasing the lower block’s length in summer to keep poorest family well being unchanged and reaching social equity. For the upper block’s consumers, we recommend applying seasonal water price to keep under control their water use evolution. Second, in the regional study, we find that the long run water price elasticity is more important in the lower block than the upper one. Moreover, water demand is sensible to price in regions characterized by economic dynamism. We think that a decentralized water pricing system can perfectly control water use especially by upper block’s consumers

Full textThreatened by the economic and social development, water is an increasingly rare good. More than ever concerned, Tunisia achieved a successfully water supply management policy. Today, this policy reached its limits with a mobilization rate of 87%. Hence, efforts should target to the demand management. Understanding farmer's strategies and identifying the parameters controlling production technologies are the fundamental elements to modify the consumption of irrigated sector without compromising production objectives. Ln this regard, the objective of this investigation is to analyze the performance of irrigated farms in the region of Sidi Bouzid. First, farm's survey was carried out in both public and private irrigated areas. Second, an analysis of the production system within theses farms showed an appropriate technology process. Moreover, the application of Data Envelopment Analysis (DEA) approach allowed the measurement of technica1 and allocative efficiency. Empirical findings revealed a technical inefficiency use of inputs. The average technical efficiency of water resource was onl y 68%. The comparison between both production systems revealed more important resources wasting in private farms than in public ones. Thus, the surface weIl creation strategy, as a second source of irrigation, was found to be against the sustainable use of an already overexploited ground water. However, such strategy is justified when analyzing allocative efficiency scores. Lndeed, the profitability of an activity, based on wells irrigation, appears to be much more interesting than that based on public resource. The average allocative efficiency of private farms was 73% compared to only 53% for public farms. The Horticultural cropping practice is a determinant factor of this profitability. In addition, results indicate the negative effect of land structure (area and a number of plots) and land input intensification on technical efficiency

Full textNorth Africa offers immense possibilities for archaeological research. Until now, those who were dedicated to the Roman hydraulic installations in Tunisia were concerned only aqueducts, Water Temples, same thermal baths and cisterns. These works focussed primarily on the historic and architectural study of buildings without evoking the problem of management of the water in the city. Therefore, we decided that our approach to this question particularly on the city of Uthina. The comparative study can help us to understand the hydraulic network of the city of Uthina, and to restore it. Our study includes 17 North African Roman cities. We have chosen the best known and most published cities, dating from the second and third centuries AD, and the cities that have a discernable hydraulic distribution system with a reconstructable urban network. After we reproduced the plan of the hydraulic works and were able to describe their function, we restored the networks which connected the various hydraulic buildings of the city. Besides the survey work and study on site, we made a model of the cisterns, the arrival of the aqueduct and the “castellum divisorum”. The site modelling of Uthina allows us to replace buildings in their relative position, and to restore the whole hydraulic network. The 3D modelling can reproduce the necessary simulations to enable an understanding of the function of the network and inform hypotheses about their restoration

Full textTourism, the world's leading industry with 1186 million international arrivals in 2015, is recognized as the priority sector of development of the LCDs (Least Developed Countries) through its direct, indirect and induced effects. Since the late 1960s, Tunisia has opted for a development strategy based on tourism activities. Since the early 1970s, tourism has been a key sector of the Tunisian economy: the deficit’s rate of coverage of the payments’ balance reached 97.7% in 1988. However, since the early 2000s, Tunisian tourism suffers from a low quality brand image, a strong dependence on the European market and major tour operators and a lack of diversification. The achievements of this sector, which has been for a long time considered as a vector of economic growth, seem to be overestimated.To overcome these problems, the State has chosen, since the late 1980s, a national strategy of diversification through the setting in tourism of Southern Tunisia. Currently, this part of the country became a tourist area of high standards including a golf course of 150 hectares and an international airport. However, the choice of tourism-oriented development is of concern, given the characteristics of the Saharan environment and the way in which Saharan tourism is marketed.This thesis aims to analyze, from an economic point of view, and to evaluate the suitability and relevance of the strategic choices which have been made in the tourism sector, particularly in the Saharan zone, taking into account the nature of the milieu characterized by an arid climate. The economic, environmental and social impact of tourism on these fragile environments could be particularly critical.Economically: on the one hand, this choice corresponds to a commodification of an exhaustible natural stock, whose existence is conditioned by access to water, which has created rivalry and conflicts in the use of the resource between the two sectors, namely, tourism and agriculture. On the other hand, the short duration of stay which does not exceed on average 1.3 days, can limit the positive fallout of tourism in these regions.Environmentally: the rival but not exclusive character of water would place it in the category of "common goods" whose availability can be influenced by the "mass effects", which leads us to consider a risk of "tragedy of commons".Socially: in addition to the social distortions that can arise in situations of usage conflicts around the resource, the jobs created in this sector are seasonal and low-skilled, which may negatively affect a real local development process in these regions.In our analyses, we used several theoretical and empirical methodological tools and approaches within a macroeconomic framework. We have mainly used cointegration techniques and error correction models adapted to the study of time series in addition to statistical analyses over the period between 1970 and 2014

Full textIIn central Tunisia, the agricultural intensification of irrigated agriculture generates local and regional environmental impacts, linked to an increased consumption of inputs and resources, including water and soil. In favor of a more sustainable agriculture and in order to inform public policies of agricultural development, it is necessary to assess the impacts of agricultural practices and water and soil conservation planning (WSCP), and this at the territory scale. The question is how to implement an environmental assessment approach in a context of 1) scarcity of reliable data including statistics, and complexity of farming practices, 2) prominence of socio-economic issues over environmental concerns 3) lack of knowledge of the perception of local actors on these issues and therefore of difficulty in identifying relevant indicators (scientific and of the stakeholders) and mobilizable. We propose an innovative approach to design and implement a participative approach involving different types of actors, to enable them to get more insights into each other's logic and perceptions of the impacts of agricultural practices and WSCP. This approach is designed to produce quality information by valuing local knowledge, share and take into account the perceptions of different stakeholders, and finally, build a consensus to contribute to the development of more effective WSCP policies. This approach has been structured in two main stages: the design of a community of practices articulated to a participatory systemic rapid diagnosis and the implementation of participatory workshops. The evaluation mobilized a dual mechanism including external observers and a satisfaction survey among participants. The survey is based on an evaluation grid of this approach, its outcomes and its short term induced effect. Sharing and taking into account the information and data collected, as well as the expertise and perceptions of the various stakeholders, has made possible to produce information deemed satisfactory or very satisfactory by all the participants. This nourished the knowledge of almost all the stakeholders and contributed to a constructive dynamic of collective learning. Our approach has contributed significantly to the evolution of perceptions and to a stronger mutual understanding between government officials and farmers. A dashboard grouping the indicators mobilized by each stakeholder was discussed and allowed to highlight convergences and differences in their analysis grids. The gradual and adaptive structuring of the approach, the choices of the stakeholders, the venues for the workshops and the use of a neutral facilitator were very important factors for the commitment and the mobilization of the stakeholders, in particular at the central scale, in this operational space for consultation on territorial issues, agricultural practices and WSCP. This work demonstrates the interest of integrating the engineering of consultation and environmental assessment within one approach and its feasibility in a difficult context for the ACES policies implementation

Full textGrand Sousse, oriental part of Sousse governorate, shelters one of the most important regional metropolises of the country, with a concentration on the littoral fringe of the human and economic activities. The demographic explosion and the generalization of the sideboard in drinking water make an important home of water consumption. Now this region is also very marked by the aridity, the main cause of low local resources. Dependent on nearby regions for its water supply, Grand Sousse leads for a long time a running to the harnessing to satisfy growing needs. The traditional political strategy of mobilization and transfers of the resources ending, the future management recommends the extensive appeal to the not conventional resources, some treated waste water and desalinated waters. It is about one of the main control levers of intervention there which Grand Sousse can promote for an "integrated management" of the hydraulic system, besides a management of the demand centred on the savings of water. The thesis mobilized direct inquiries on a representative sample of households, industrial units and hotels; they allowed to draw up balance sheet actions led in the sense of this new orientation, and to understand better the constraints and the met obstacles. The cartographic was a tool indispensable to the representation of this inadequacy between supply and demand in water, the network of supply and distribution, and constituents of the future management of the water. The forward-looking approach allows pulling the air-raid siren at the threat that makes weigh the trend-setting evolution of the demand on the socio-spatial balances, and proposes alternative solutions of this evolution

Full textIn rural areas, water management induces changes in technologies and in agricultural practices that face farmers. Farmers’ behaviors include both a desire for innovation and a land attachment through local customs, practices and representations. This identity attachment has often been regarded as an obstacle to the introduction of new techniques rather than an opportunity to be seized. This work, based on the case of Diar Hojjej (a coastal area of Cap Bon, Tunisia) aims to understand how rural entrepreneurship can be an engine to convey a strong environmental constraint area (water irrigation) to sustainable agricultural development, while taking into account the territory’s identity. The territory’s identity would it only be an obstacle to rural entrepreneurship? And what would be the most relevant model of entrepreneurship? [etc.]

Full textThe Merguellil basin in central Tunisia provides an illustrative example of hydrological processes profoundly modified by human action. The Wadi Merguellil, the main river of the basin, has experienced an extremely marked socio-hydrological evolution. Its current state is the legacy of a long history of interactions between man and his environment. Truly, it is currently intermittent over most of its course, but the statements of farmers and archival records reveal that this was not the case at the beginning of the last century. The use of ancient information from archival documents has shown that the Wadi Merguellil was supported mainly by the overflow of the confined aquifer of Bouhefna. During the years 1974-1975 and in order to transfer groundwater resources from the Merguellil basin to the coastal regions, a management plan was put in place. The aim of this plan was to reduce the level of the Bouhefna aquifer so as to reduce '' losses '' by evaporation in the Wadi Merguellil and minimize the groundwater flow towards the nearby Haffouz aquifer. As expected, this strategy led to a reversal of the hydraulic gradient inferring the drying up of the overflow springs, the emptying of the alluvial aquifer and the disappearance of the Wadi Merguellil baseflow during the period 1976-1978. The hydrodynamic model established in this thesis suggests that the averaged groundwater flow that was feeding the Wadi before the hydraulic gradient reversal is around 9 hm3. Currently, it is rather the floods of the Wadi that feed the alluvial aquifer and the shallow aquifers. The average flow infiltrated during the propagation of flood events is estimated at 17 hm3 in the section of the wadi between the Haffouz station and El Haouareb dam for the year 2013-2014.Though, the exploitation management plan of the Bouhefna aquifer was based exclusively on hydrodynamic considerations without taking into account the evolution of hydro-agricultural practices. Indeed, the disappearance of the baseflow of the Wadi Merguellil has forced farmers to abandon traditional irrigation canals and opt for the installation of motor pumps and the establishment of deep wells. This feedback on the change in the Wadi flow regime has further disrupted the hydrological balance. This resulted in an excessive exploitation of the groundwater with an observed current decrease of the piezometry higher than 1m/year and a reversal of the hydraulic gradient between the Bouhefna aquifer and the Haffouz aquifer. The hydrodynamic model suggests that the average flow exchanged by vertical drainage has decreased from 8 hm3 in 1970 to 2 hm3 in 2015. In the opposite direction, the average flow transiting from the Haffouz aquifer to the Bouhefna aquifer has increased from 1 hm3 in 1970 to 6 hm3 in 2015, imposing a risk of salinity in the long term.The transfer of water from Bouhefna to the coastal regions, even though it is widely disputed by the local populations, has never been put forward as a factor explaining the hydrological evolution experienced locally. The work of this thesis allows to show how much this transfer of water has influenced the hydrological regime of the wadi. However, by not omitting their own responsibilities in these dynamics, farmers are lucid. Indeed, the hydrodynamic model suggests that the cumulative part of groundwater volumes mobilized by the latter after the disappearance of the Wadi baseflow is comparable to that for drinking water. The results of this thesis are in line with research in socio-hydrology that calls for integrating social aspects into management plans to ensure sustainable development of water resources

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 textTravertine, known as lapis tiburtinus during Roman times, are continental limestones precipitated in calcareous environments from thermal waters of hot springs (travertine) or cool waters of karstic springs (calcareous tufa). This phenomenon is well-known during Classical Antiquity and had been described by several ancient authors (Strabo, Pliny the Elder, Vitruvius) who depicted a stone that forms extremely rapidly, a stone that outlines the landscape and which is largely used for construction (e.g. The Colosseum in Roma, the Greek temple at Segesta in Sicily). These deposits are widespread on Earth’s surface showing various morphologies and are great sedimentary records of climatic and hydrologic conditions. Thus they represent valuable proxies for palaeoenvironmental studies. The notion of anthropogenic travertine takes into consideration human impact on these deposits and on travertine-depositing waters. It is documented by the study of the roman site of Jebel Oust, Tunisia, where the exploitation of a hot spring is attested from the first century A.D. to the end of Late Antiquity. The site is characterized by a temple settled around the spring’s vent associated with Roman baths located downstream and supplied with hot water via an aqueduct. Our geoarchaeological approach brings to light the anthropization of the regional geosystem expressed by an entire control over the hot spring and its associated deposits. Furthermore the study of travertines preserved in the archaeological structures reveals precious and original information about water cult and bathing practices during Antiquity (thermal rooms function, water management, repair phases, states of neglect and decay). Moreover, geoarchaeology of anthropogenic travertine intends to offer a new approach of research‘s problematic dealing with water managements and integrating human impact on travertine’s development

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?

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 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 textThe present thesis deals with the problem of water irrigation in the peri – urban oases of the district of Gabes. Through a look-back at the past , the thesis tries to focus on the existing relations between the scarcity of water resources , the great social changes as well as the ways of management of this resource hence the reorganization of the agricultural system within the oasis. Being located close to a coastal area increasingly attractive that resulted in an urbanization wave the rural oases are facing an unprecedented shift caused by human pressure due to rural drift. Consequently, this shift has put the oases face to a paradox. As a matter of fact, this research is mainly interested in the current dynamics as well as in the social, agricultural and spatial diversity in the midst of the oasis of Gabes. It also reveals that the severe decline of agricultural activities, caused by either abandoning this traditional work or by urban expansion, has not prevented the advent of some new strategies of adaptation that would fit the new urban, economic and social context. However identifying the various contributors to water management on the local level , their logic and the modality of governing of the water resources which are linked to the social, economic and political choices of our country( decentralization- disengagement –privatization – contribution ) permits to better understand the nature and the level of both the economic and political factors at stake. The conclusion shows that the water scarcity in the oasis is not only physical but it is also the result of the overexploitation of the resources in addition to its governance mode. Unfortunately, the “ Group of collective interest” GIC which is a social structure created by the State in order to ensure a both reasonable and fair management of water, turned to be the main cause of its scarcity , waste ,debt and the discrimination between users. Thus it is recommended that a suitable policy be based on sustainable development of the oases as multifunctional heritage where the environmental, the economic, the social and the cultural aspects are kept in perfect harmony

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 textAs a result of the evolution of the external envirnment which has been affected by a liberal ideology, Tunisian public organizations have been seeking for an efficient management model able to improve public notoriety. This quest for efficiency has incited us to study ways of developing competences among employees in public organizations. The research attempts to define the major factors that are likely to affect competence management. It is hypothesized that both the cultural context and the Human Resource Management strategies may influence the success of the implementation of a competence-based management approach within public organizations. First, the study focuses on the ambiguity of competence management, showing that the former practice is far from being homogeneous or neutral. We, then, present a qualitative longitudinal case study of a big Tunisian organization. The part of the research has enabled us to examine those difficulties faced in implementing restructuration projects in the Tunisian public sector. The second part of the study describes the most important results of the dysfunctional analysis that has been carried out within the observed organization. We demonstrated that the Human Resource Management system- a traditionally based approach- does not encourage the management of competences among workers. Suggesting a new management tool has, thus, proved to be necessary. Finally, the study attempts to shed lights on those cultural caracterstics of Tunisian public organizations and which may hinder the implementation of competence-management practices

It is founded on the notion of an international hydrographic basin which is presented as the field of application imposed by nature and scientific knowledge. It disclaims the new norms which alllow the right to question utilisation and protection of the waters. It presents co-operation such as it exists and such as it would be desirable that it should evolve. It envisages the treatment of the differences

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
