Book Description
Human schistosomes (blood flukes) are digenetic trematodes that spend the adult part of their life cycle in humans and a further part in aquatic snails. Despite advances in chemotherapy, schistosomiasis is still a significant infection in the populations of several countries in the tropics. This book replaces a previous volume Schistosomiasis: Epidemiology, Treatment and Control (Heinemann, 1982) by Jordan and Webbe. All chapters have been rewritten by internationally renowned workers. Ultrasound, expected to aid identification of early disease in the field and increase our understanding of its evolution, is discussed in a new chapter. Others, each with an extensive bibliography, review the parasites and their snail intermediate hosts, epidemiology, clinical manifestations and pathology, diagnosis, immunology, drugs and patient management and control. Limitations of the role of chemotherapy in morbidity control are discussed and the need for flexibility in control interventions in the varied epidemiological situations is stressed. An interdisciplinary approach may be necessary to reduce transmission by appropriate measures against the snail intermediate host, and to implement public health measures, including the provision of safe water (with many other medical and social benefits) and health education. This comprehensive volume is for public health workers involved in the prevention and control of the disease, for physicians, and for students and teachers of many disciplines. It also provides a reference book for health planners, social anthropologists, health educators, water and sanitary engineers and others engaged in improving health in the tropics. Physicians in temperate countries will also find it a useful reference book as schistosomiasis, often acute, is being diagnosed more frequently in those returning from holidays in endemic areas.

Book Description
his research report discusses ecological aspects of schistosomiasis transmission and options for its control in irrigated areas in Africa through environmental measures. Human schistosomiasis is endemic in 46 African countries.After being infected by larvae emerging from human excreta and urine deposited in the water, freshwater snails act as intermediate hosts.

Book Description
Issues a call for action to correct the gross neglect of the health consequences of water impoundment and irrigation projects. Arguments and proposed lines of action respond to the documented magnitude of human misery and incapacity that follow when water development projects make no provision for disease control. Concentrating on parasitic diseases as the most dramatic and reliable indicators of adverse effects on health, the book aims to persuade the financiers, planners, and managers of these projects to make health concerns a central part of the development dialogue. To this end the book draws upon a large body of evidence to demonstrate both the magnitude of project-related health risks and the feasibility of their prevention and control. Citing the traditionally passive role of the health sector as a contributing factor, the book also aims to encourage health authorities to enter the project cycle with a more insistent voice. Throughout the book, emphasis is placed on recent knowledge about parasitic diseases that underscores the feasibility of formulating policies where the goal of economic progress is compatible with the protection and promotion of health.

Book Description
Irrigated agriculture and the use of water resources in agriculture face the challenges of sustainable development. Research has advanced our knowledge of water use by crops, soil-water-solutes interactions, and the engineering and managerial tools needed to mobilize, convey, distribute, control and apply water for agricultural production. However, the achievements booked in user practice have revealed the need for new developments in the areas of resource conservation, control of environmental and health impacts, modernisation of technologies and management, economic viability and the social acceptance of changes. The contributions to Sustainability of Irrigated Agriculture cover most of the relevant disciplines. Besides its multidisciplinarity, the different origins, experience, backgrounds and practices of the authors provide a wide, in-depth analysis of the various aspects of water resource utilization in agriculture. The papers review scientific, technical and managerial aspects, highlighting the main problems, issues and future developments. The book covers the different aspects of sustainability, including environmental, technical, economic, institutional and social ones. Advances in irrigation science and engineering are dealt with, both on- and off-farm. Special attention is paid to the different components of water quality management, to the transfer of technology, and to capacity building.

Book Description
A global history of malaria that traces the natural and social forces that have shaped its spread and made it deadly, while limiting efforts to eliminate it. Malaria sickens hundreds of millions of people—and kills nearly a half a million—each year. Despite massive efforts to eradicate the disease, it remains a major public health problem in poorer tropical regions. But malaria has not always been concentrated in tropical areas. How did malaria disappear from other regions, and why does it persist in the tropics? From Russia to Bengal to Palm Beach, Randall M. Packard's far-ranging narrative shows how the history of malaria has been driven by the interplay of social, biological, economic, and environmental forces. The shifting alignment of these forces has largely determined the social and geographical distribution of the disease, including its initial global expansion, its subsequent retreat to the tropics, and its current persistence. Packard argues that efforts to control and eliminate malaria have often ignored this reality, relying on the use of biotechnologies to fight the disease. Failure to address the forces driving malaria transmission have undermined past control efforts. Describing major changes in both the epidemiology of malaria and efforts to control the disease, the revised edition of this acclaimed history, which was chosen as the 2008 End Malaria Awards Book of the Year in its original printing, • examines recent efforts to eradicate malaria following massive increases in funding and political commitment; • discusses the development of new malaria-fighting biotechnologies, including long-lasting insecticide-treated nets, rapid diagnostic tests, combination artemisinin therapies, and genetically modified mosquitoes; • explores the efficacy of newly developed vaccines; and • explains why eliminating malaria will also require addressing the social forces that drive the disease and building health infrastructures that can identify and treat the last cases of malaria. Authoritative, fascinating, and eye-opening, this short history of malaria concludes with policy recommendations for improving control strategies and saving lives.
