The overall objective of Reservoir Eutrophication: Preventive Management is to present the environmental and anthropogenic factors associated with the process of eutrophication and algal blooms in the Rio Verde reservoir and propose lake use and management technologies in order to minimize the problem. Eutrophication process in Rio Verde reservoir with the occurrence of intense algal blooms is a consequence of the interconnection of different climatological, hydrological, morphological, physico-chemical and biological factors, which occur not only in the watershed but also in the reservoir. Reservoir Eutrophication: Preventive Management compiles the information gathered from the development of a broad research program in Rio Verde watershed, from 2008 until 2010. Rio Verde reservoir, which was built in 1976, is located in the Metropolitan Region of Curitiba, capital of the state of Paran? in South Brazil. This reservoir is mainly used for supplying water to one of PETROBRAS Refinery. However, the reservoir is to be used for supplying drinking water to the population and that is why better understanding this system dynamics is a great concern. The book is the result of an interdisciplinary research program, which has involved more than 150 researchers, with the aim of defining a watershed management preventive system in order to prevent eutrophication processes. This way, the book combines academic rigor with practical applicability and is of interest for both researchers and technologists working in watershed management. Reservoir Eutrophication: Preventive Management is of interest to researchers and technologists that wish to examine specific characteristics of tropical climates. It is of specific interest to developing countries and for researchers interested in knowing the developed methodology adapted for temperate conditions.

Le lac Tchad et son avenir sont au cœur des préoccupations politiques régionales et internationales. Cet espace vital, à la charnière de l'Afrique de l'Ouest et de l'Afrique centrale, a longtemps fasciné, depuis les géographes arabes au Moyen-Âge jusqu'aux explorateurs européens du XIXe siècle. Il suscite aujourd'hui des interrogations fortes sur l'environnement, l'eau, le climat et le développement régional. Le lac Tchad va-t-il s'assécher ? Quelles seraient alors les conséquences pour les 13 millions d'hommes qui en dépendent, sur un rayon de 300 km ? Les discours publics qui traitent de l'avenir du lac Tchad, le plus souvent alarmistes, sont dans l'ensemble sources d'une grande confusion et entretiennent une image brouillée de la situation. Une connaissance précise des réalités est pourtant nécessaire pour construire une vision partagée de cet avenir et adopter une stratégie qui permette de relever les défis du développement durable du lac. La Commission du bassin du lac Tchad (CBLT) a commandé à l'Institut de recherche pour le développement (IRD) une expertise collégiale sur la préservation et le développement du lac Tchad. Cette expertise, réalisée par un collège d'experts pluridisciplinaire et paritaire Nord-Sud, recense les connaissances actuelles sur le lac et identifie les différents choix politiques susceptibles de stimuler son développement. Elle aboutit à une série de recommandations utiles aux décideurs politiques en matière de soutenabilité environnementale, de sécurité alimentaire et d'emploi. The future of Lake Chad is at the centre of regional and international political concerns. This natural habitat that links West and Central Africa fascinated Arab geographers in the Middle Ages and, later, European explorers in the 19th century. Today, it raises important questions about the environment, water, climate, and regional development. Will Lake Chad dry up? What then would be the consequences for the 13 million humans within a radius of 300 km who…
