"Nombre de grands lacs de la planète ne sont, en réalité, pas assez vastes pour faire face aux usages qui en sont faits par les activités humaines, telles qu'elles se déploient depuis plus d'un siècle. Les limites de ces macro-écosystèmes à dimension continentale se manifestent par toute une série de pathologies qui les affectent et qui s'accompagnent d'une dégradation des services écosystémiques rendus : pêche, approvisionnement en eau, autoépuration, dilution des pollutions, services culturels et récréatifs, etc. En outre, l'ensemble des tensions en cause s'exerce désormais dans un contexte de multi-stress dû au changement climatique. La taille 'grand lac', l'inertie et la complexité dont elle dote les systèmes concernés, se traduit par des conditions d'expositions et de réponses inédites, difficiles à intégrer en termes de gestion. L'ouvrage propose une analyse pluridisciplinaire de diverses expériences de restauration menées sur des grands lacs de la planète (réussites et échecs). Riche d'enseignements sur la sauvegarde et la préservation du patrimoine lacustre mondial, cette étude ouvre des pistes de réflexion sur les futurs défis écologiques à relever pour préparer les systèmes 'lac-bassin versant-société' à la nouvelle donne, en termes de climat et de pollution. Ce livre est destiné aux étudiants, enseignants et chercheurs, aux gestionnaires des milieux lacustres, ainsi qu'au grand public intéressé par la préservation et la restauration des grands lacs"--Page 4 of cover.

This volume contains most of the scientific contributions to the workshop ``Prediction of Agricultural Nonpoint Source Pollution: Model Selection and Application'' held in Venice, in the historic Ca' Vendramin Calergi, in June, 1984. Other contributions of specialists who were not able to attend the workshop have also been included in an attempt to make the work more complete.It is hoped that this collection will be useful to planners who operate in the field of agricultural diffuse source pollution, since several contributions are state-of-the-art presentations and others are specialized stud

This book is an initial attempt to estimate the loads of heavy metal and nutrient loads into an industrial effluent receiving rivers of a typical industrializing catchment. It shows the effects and impacts of diffuse and point sources of these loads into the rivers, and illuminate management, capacity and policy gaps of riverine water and sediment monitoring in the sub-Saharan countries perspective from Ethiopia. The study was done in semi-arid catchments of Kombolcha city with industrialising urban and peri-urban areas in north-central Ethiopia. The Leyole and Worka rivers, which receives industrial effluent and wash-off from the catchments' areas, were monitored for two years. This book contribute to our understanding on applicable methods to quantify loads of diffuse and point sources in data poor areas, and the most important contribution is to address the gaps in in controlling emission changes and. The results of this book contribute to the theory of river protection and understanding of water quality management of sub-Saharan African tropical rivers and sediments and provides policy options for improvement in rivers water quality of the sub-Saharan countries. In bridging this gap, this book proposed a model to estimate the total loads of nitrogen and phosphorus from a catchment.

Basics of Metal Mining Influenced Water is a must read for planners, regulators, consultants, land managers, students, researchers, or others concerned about the environmentally sound management of metal mine wastes and drainage quality. The first of a series of six handbooks on technologies for managing metal mine and metallurgical process draining, this book offers a unique, comprehensive perspective on the subject. Unlike other texts that focus primarily on acid drainage from coal mines, the authors examine both acidic and neutral pH waters that can be hazardous to the environment. Planning
