    À l’instar des wilayas du département de l’Ouest algérien, la wilaya de Sidi Bel Abbès souffre de pénurie d’eau. Dans cette région, où les écoulements sont caractérisés par une irrégularité saisonnière et interannuelle importante, les potentialités en eau sont faibles. Les ressources en eau souterraines et superficielles sont insuffisantes à satisfaire les besoins et ne répondent pas aux demandes croissantes de la population qu’elle soit urbaine ou rurale. La wilaya de Sidi Bel Abbès n’a pu supporter le déficit en eau et faire face aux aléas climatiques récents. C’est dans cette optique que les organismes gestionnaires ont fait appel à des transferts d’eau des wilayas limitrophes pour couvrir le manque enregistré ces dernières années. L’étude présentée ici contribue à la mise en place d’une base de données participant à la compréhension des modalités de gestion intra et extra-wilaya. Elle permet par la suite d’analyser les enjeux de cet élément crucial, nécessaire à toute vie et à tout développement socio-économiqueLike the wilayas of west Algerian department, wilaya of Sidi Bel Abbes suffers from water shortage. In this region, where the flows are characterized by a considerable seasonal and irregularity, the water potentials are low. Water resources in ground or surface are insufficient to meet the needs and growing demands of the urban or rural population. The wilaya of Sidi Bel Abbes couldn’t withstand this water deficit and facing the hazards climate changment recently. In this regard the administrative bodies called for water transfer from neighboring wilayas to cover the registered lack in the last years. The study is contributing to make a data base participating to understand ways of intra and extra wilayas water management. so it allows analyzing the issue of this critical factor necessary for the whole life and for socio- economic development

    Les cours d’eau méditerranéens et leurs marges sont le lieu de processus hydrosédimentaires qui sont l’objet d’enjeux écologiques, économiques et sociaux. Les articles présentent des analyses de la structure, du fonctionnement et de l’évolution de ces systèmes. Ils concernent les marges sud et nord de la Méditerranée, abordant les questions de la pénurie ou des excès d’eau, de la qualité des milieux fluviaux ou de leur perturbation

    International audienceThe aim of this study was to estimate the incidence of COVID-19 disease in the French national population of dialysis patients, their course of illness and to identify the risk factors associated with mortality. Our study included all patients on dialysis recorded in the French REIN Registry in April 2020. Clinical characteristics at last follow-up and the evolution of COVID-19 illness severity over time were recorded for diagnosed cases (either suspicious clinical symptoms, characteristic signs on the chest scan or a positive reverse transcription polymerase chain reaction) for SARS-CoV-2. A total of 1,621 infected patients were reported on the REIN registry from March 16th, 2020 to May 4th, 2020. Of these, 344 died. The prevalence of COVID-19 patients varied from less than 1% to 10% between regions. The probability of being a case was higher in males, patients with diabetes, those in need of assistance for transfer or treated at a self-care unit. Dialysis at home was associated with a lower probability of being infected as was being a smoker, a former smoker, having an active malignancy, or peripheral vascular disease. Mortality in diagnosed cases (21%) was associated with the same causes as in the general population. Higher age, hypoalbuminemia and the presence of an ischemic heart disease were statistically independently associated with a higher risk of death. Being treated at a selfcare unit was associated with a lower risk. Thus, our study showed a relatively low frequency of COVID-19 among dialysis patients contrary to what might have been assumed
