Available in PDF, EPUB and Kindle. Book excerpt: The impoundage of flowing streams profoundly alters the biology of the affected waters. One of the changes may be a vast increase in the potential for anopheline mosquito production unless appropriate control works and procedures are planned, designed, and operated. The choice is, therefore, between the probability of a disastrous "man-made" increase in transmission of malaria or a successful resolution of the continuing conflict between adverse biological pressures and control practices. There is no ready-made formula which is applicable under all circumstances to all impoundments, for variations in ecological conditions and the primary purposes of water control are practically infinite. Hence, plans for malaria control on impounded water, though following basic principles, must be specifically adapted in method to each particular project by the selection of specifically applicable alternatives as delineated by local ecology and objectives. This publication records a comprehensive body of experience in the design and operation of programs of malaria prevention on impounded water and, while certain principles here presented seem to have been established with at least a measure of finality, this manual is no final word on the subject. On the contrary, it is essentially a report of progress submitted for such value as it may have to others confronted by similar tasks.

Download or read book Malaria transmission in the vicinity of impounded water evidence from the Koka Reservoir Ethiopia written by Solomon Kibret and published by IWMI. This book was released on 2009 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction of dams in Africa is often associated with adverse malaria impacts in surrounding communities. However, the degree and nature of these impacts are rarely quantified and the feasibility of manipulating reservoir water levels to control mosquito breeding has not been previously investigated in Africa. This report describes entomological and epidemiological studies conducted around the Koka Dam and Reservoir in Ethiopia. The research findings confirm the role of the reservoir in increasing malaria transmission and provide evidence that there is potential to use dam operation in integrated malaria control strategies.

Book excerpt: Water has dominated images of the South throughout history, from Hernando de Soto's 1541 crossing of the Mississippi to tragic scenes of flooding throughout the Gulf South after Hurricane Katrina. But these images tell only half the story: as urban, industrial, and population growth create unprecedented demands on water in the South, the problems of pollution and water shortages grow ever more urgent. In Southern Waters: The Limits to Abundance, Craig E. Colten addresses how the South -- in an environment fraught with uncertainty -- can navigate the twin risks of too much water and not enough. From the arrival of the first European settlers, the South's inhabitants have pursued a course of maximum exploitation and control of the area's plentiful waters, investing widely in wetland drainage and massive flood-control projects. Disputes over southern waterways go back nearly as far: obstruction of fish migration by mill dams prompted new policies to protect aquatic life as early as the colonial era. Colten argues that such conflicts, which have heightened dramatically since the explosive urbanization of the mid-twentieth century, will only become more frequent and intense, making the shift toward sustainable use a national imperative. In tracing the evolving uses and abuses of southern waters, Colten offers crucial insights into the complex historical geography of water throughout the region. A masterful analysis of the ways in which past generations harnessed and consumed water, Southern Waters also stands as a guide to adapting our water usage to cope with the looming shortage of this once-abundant resource.
