In most developing countries wastewater treatment systems are hardly functioning or have a very low coverage, resulting in large scale water pollution and the use of very poor quality water for crop irrigation especially in the vicinity of urban centres. This can create significant risks to public health, particularly where crops are eaten raw. Wastewater Irrigation and Health approaches this serious problem from a practical and realistic perspective, addressing the issues of health risk assessment and reduction in developing country settings. The book therefore complements other books on the topic of wastewater which focus on high-end treatment options and the use of treated wastewater. This book moves the debate forward by covering also the common reality of untreated wastewater, greywater and excreta use. It presents the state-of-the-art on quantitative risk assessment and low-cost options for health risk reduction, from treatment to on-farm and off-farm measures, in support of the multiple barrier approach of the 2006 guidelines for safe wastewater irrigation published by the World Health Organization. The 38 authors and co-authors are international key experts in the field of wastewater irrigation representing a mix of agronomists, engineers, social scientists and public health experts from Africa, Asia, Europe, North America and Australia. The chapters highlight experiences across the developing world with reference to various case studies from sub-Saharan Africa, Asia, Mexico and the Middle East. The book also addresses options for resource recovery and wastewater governance, thus clearly establishes a connection between agriculture, health and sanitation, which is often the missing link in the current discussion on 'making wastewater an asset'.
Contains the engineering tools and concepts that have proven useful in planning, constructing, and maintaining drainage systems for successful long term irrigation projects. Provides a ready reference and guide for making accurate estimates of drainage requirements.
The AQUASTAT Programme was initiated with a view to presenting a comprehensive picture of water resources and irrigation in the countries of Africa, Asia, Latin America and the Caribbean and providing systematic, up-to-date and reliable information on water for agriculture and rural development. This report presents the results of the most recent survey carried out in the 18 countries of the Middle East region, and it analyses the changes that have occurred in the ten years since the first survey. It contains the detailed profiles on the situation in each country.
This publication provides guidance for water users and districts in selecting, managing, inspecting, and maintaining their water measurement devices. Describes the standard methods and devices used to measure irrigation water. Acquaints irrigation system operators with other established but less common methods and with new or special techniques. |
