Approche, de la gestion intégrée du littoral et des bassins fluviaux « GILIF » Cemali, Nedjoua; Benazzouz, Mohamed Tahar Like many coastal areas around the world, Skikda coastline is subject to disturbances that threaten its balance at various levels; ecological, sedimentary, sociological, and economic. With 160 km of coastal lineage, a very strong coastal dynamics, and a great conflict of use, Skikda coastline is a complex system at the interface between land and sea. The watershed is a sedimentary source of supply necessary for coastal balance, and any activ ty that contributes to the disruption of this supply will lead to a morphodynamic imbalance. This observation was a starting point for a reflection on the space that must be retained to manage and protect Skikda coastline. The main objective of this disertation is to strengthen geomorphological knowledge in a context based on the link between the watershed and the coastline. In order to achieve this objective, two approaches were used. A systemic approach based on the concept of system, integrating the upper land which is the watershed with the coastline;and a morphodynamic approach that relies on the digital processing of satellite images (Landsat 8) and aerial photographs (1960, 1970, 1988, 2002) through the application of Geographic Information Systems. The results obtained in the two areas studied, which are the Saf-Saf watershed and the mouth, demonstrate a regressive situation of the mouth and its nearby beach L’arbi ben Mhidi. The interpretation and discussion of these results allow to identify the factors that explain this morphological evolution, such as the impact of sedimentary retention at the dam level, deve lopments on the shore, and weather-marine forcing.

La reduction des disparites inter-quartier avec une redistribution des equipements. Cas de la ville de Boussaâda. Taibaoui, Saad; Khalfallah, Boudjemaa; Layeb, Hafid The reduction of socio-spatial disparities between the districts of the city of Boussaâda, can takes at least two paths, one towards the relocation of people to weave a social mix, the other relies on the strengthening of services and equipment in order to to make precarious outlying neighborhoods more competitive and attractive. The quantitative analysis of the socio-spatial disparities between the districts of the city of Boussaâda, confirms the ghettoization of the peripheral districts, with (6) as index on the typology of Poulsen, (0,780) as index of uni-group Segregation. The weighted combination of these results with the spatial factors defined by the success rates for the BAC and BEF exams and the travel time to the city center and neighborhoods results in an overall zonal suitability index (IAZG), With (0.41 ) rating given to the Quartier Maitar summarizes the infinitely low level of service available to the populations of the district. These results are the conclusion of a combination of several methods, MCDA (AHP) and Zonal Fitness (IAZG). The contribution of this thesis is the construction of an IAZG, composed of several factors of socio-spatial disparity between the districts of the city of Boussaâda, used as an index of inter-district disparities it will be the basis of the decision to allocate the facilities across the city's neighborhoods. It is the result of a weighted combination between the factors of the multi-criteria decision taken by several actors in a transparent environment and which respects the principles of equity and sustainable development. The Hierarchical Analysis Procedure (AHP) (Saaty T., 1990) is used for weighting decision factors in the Multi-Criteria Decision Aid (MCDA) method. The result of this procedure is the ranking of the proposed alternatives, with the aim of reducing disparities between districts. Without ambiguity the final decision is taken by the politicians and in the presence of all the actors who participated in the decision

Sociologie de l’espace habité en Algérie Boumali, Badr-Eddine; Tamine, Rachid The notion of ""inhabiting"", developed during the second half of the 20th century, has made it possible to place the human individual at the center of spatial theories. However, this phenomenological-inspired notion also contributed to widening the gap between formal geography, which focused on spatial statistics and models of territorial production, and geography of spatial existence, aspiring to understand geographical space as a world lived by individuals. The objective of this thesis is to bridge this gap by articulating the two approaches, with a view to a better understanding of inhabited space in general and the Algerian territory, which served as the empirical field of investigation. As reflectors of urbanity, public spaces are today the object of increased attention on the part of developers and planners in a context of spatial production by society. This research analyzes the relationship that city dwellers have with their living spaces, which are essential in the structuring of public spaces. In effect, in their practices, in the projection of themselves in urban space, city dwellers participate in their production. These epistemological precepts allow us to approach the practices of public spaces through the concepts of appropriation and inhabitation, and to pay particular attention to the uses implemented by the inhabitants and users in their living spaces. This allows us to shed light on the meaning of appropriation of public spaces and to clarify the meanings related to representations. The Critical Realist approach was chosen as the research paradigm because it accepts external reality and shows the explanations that best produce desired results and uses mixed methods (qualitative and quantitative) combining objective and subjective perspectives. This research focuses on the implementation of public space as a category of public action in Constantine. The first analysis is a comparison of policies, spaces produced, and the consideration of uses in the processes of space production. It shows how the city of Constantine, which has a ""spatiality"", seeks to structure the territories and its image (of spaces and uses). It keeps reasonable plasticity, which allows a considerable margin of maneuver in the construction of solutions for the development of spaces. In a second step, the thesis restores the construction of problems and solutions to public space planning. It demonstrates how the formalization of the category in a project through a system of action is done progressively throughout a process and at different scales of urban production. This progressive formalization is constrained by dependencies on the past, the context and the objectives. The research concludes that these practices face significant barriers and complexities under current conditions. However, they also offer rich insights into emerging modes of user-driven urbanism and city politics that resonate with Lefebvre's social project to produce space.

إشكالية النفايات المنزلية في مدينة قسنطينة بين حماية البيئة وتحقيق التنمية المستدامة. غرفي, سهام; بوالصوف, رابح Cities are ecosystems with social, economic, environmental and, most importantly, structural dimensions, as they have become an urban morphological and physiological characterized by the consumption and dumping of what they do not need, especially household waste due to its association with the daily activities of the population, which has become a major threat to the environment, and the concept of sustainable development has emerged as a concept that aims to achieve economic development and social well-being with the least possible consumption of natural resources and minimal environmental damage and pollution, especially waste pollution, which the environment in its various elements has become unable to dispose of it, given its high quantity and different constitution of waste. In Algeria, most of its cities, especially Constantine, face many shortcomings in managing and treating household waste domain, which prompted it to adopt a policy of sustainable management by enacting laws, and supported by various public institutions and national programs and local plans, this policy resulted projects related to the sustainable management of household waste and its treatment by scientific and safe environmentally ways. Our study included an analysis of the reality of household waste in the city, which showed that the city still relies on traditional management, and therefore the concept of sustainable development has not been realized even slightly in the management field, and in terms of achieving the performance of sustainable development indicators from the environmental, institutional and financial aspects, it was found that the performance is poor and the service provided to the population is poor also, and therefore, convergence and interaction must be created between the administration, private traders and residents to clarify the sustainable development concept in the household waste management field to ensure the achievement of its goals in the city.
