Taschenbuch. Zustand: Neu. Neuware - The challenge of urban poverty is growing every year. It is predicted that over 95% of global population growth between 2000 and 2030 will take place in the cities of the developing world. If current trends continue, the huge majority of those will end up in slums. Tackling urban poverty, however, has had a lower profile than other of the Millennium Development Goals, for example the one on water - despite the efforts of major players such as UN-Habitat.

Taschenbuch. Zustand: Neu.

It examines the costs and general suitability of the different technologies to enable farmers and policy makers to make informed choices.More than one billion people still do not have access to safe drinking water, and almost two billion people suffer from diseases arising from contaminated water due to poor sanitation. Irrigation is essential for the basic food requirements of billions of people. The growing world population and global climate change make the challenges of providing adequate clean water, sanitation, and food ever more pressing. At the heart of effective irrigation lies the problem of lifting or pumping water. This handbook provides a detailed review of the water-lifting technologies available for irrigation, along with new information covering the provision of drinking water for humans and livestock. Water Lifting Devices has long been the authority on the subject and this new third edition provides updated essential practical information for farmers, development workers, and all who need to make informed choices about water lifting technologies.…
