What do climate models predict for the rainfall where you live? What about evaporation or runoff? Should your local community consider constructing new dams or do the existing water storages appear adequate? What about the availability of water for irrigation farming? Do the predictions differ between different climate models or do all the models basically predict the same changes in water availability where you live? These are all simple questions but it is surprisingly hard for an individual, whether they be a farmer, water resources engineer, teacher or interested citizen, to answer them. As researchers active in the field we could not answer the questions either. In fact, we had never seen a compilation of the rainfall, evaporation and runoff predictions made by all the different climate models. The Atlas contains maps and tables that document model predictions contributed by international climate modelling groups to the 2007 4th Assessment Report of the Intergovernmental Panel on Climate Change. The predictions are made available here via the wonders of the internet and ongoing cooperation by the international climate modelling community who routinely archive their results. The maps and tables in the Atlas document rainfall, evaporation and runoff estimates for the 20th century along with predictions of the same quantities at the end of the 21st century. Whatever your interest, we hope you find the Atlas as helpful as we do.

This book on the History of Water Development in Kenya transverses through a matrix of infrastructural development, administration, policy, legal and legislation framework, and evolution of various water supply technologies in an inimitably comprehensive approach. The book has carefully constructed the development over one century timeline of water supply and provided the future prediction of the services. The book is a quest to track and understand the origin, the development and sustainability of water supplies within 100 years of its 1st water supply constructed by the railways as the pioneer of water supply in Kenya. It interrogates how the water legislations, policies and administration came to be and what the drivers of water supplies were, when the 1st water reforms mounted and the status of the reform implementation. It elucidates on the role of development partners in influencing the choice of technology, policy and legislative framework. Preparation of this book took fifteen years of passionate research from Kenya National Archives; Kenya Railways; Ministry of Water Development; Colonial archival materials at Rhodes House, Oxford, UK; and the British Institute in Eastern Africa. The research findings have been disseminated in several peer reviewed journals; and several presentations in local, regional and international conferences. Eng Ezekiel Nyangeri Nyanchaga is an Associate Professor, Department of Civil and Construction Engineering, University of Nairobi, Doctor of Technology holder in Civil Engineering, Tampere University of Technology, Finland. Professor Nyangeri is a licensed and practicing consulting engineer with over 35 years of professional experience and over 28 years of academic teaching experience at the University of Nairobi, Kenya.

Rainwater tank systems have been widely adopted across the world to provide a safe local source of water in underdeveloped rural areas, and as a substitution for mains water for non potable end uses in water stressed urban areas. They also provide flood control in monsoonal climates like Korea or in combined sewer systems like in Germany. The importance of these systems in cities has grown, as water managers seek to provide a range of decentralised solutions to supply constraints of current water supply systems, whilst reducing the impact of urban development on the natural environment, and increasing resilience to climate change. Rainwater Tank Systems for Urban Water Supply is based on a comprehensive, multi-million dollar research program that was undertaken in South East Queensland (SEQ) Australia in response to the Millennium drought when the water supply level in the regions drinking water dams dropped to 17% in July 2007 and the area came close to running out of water.

Owing to climate change related uncertainties and anticipated population growth, different parts of the world (particularly urban areas) are experiencing water shortages or flooding and security of fit-for-purpose supplies is becoming a major issue. The emphasis on decentralized alternative water supply systems has increased considerably. Most of the information on such systems is either scattered or focuses on large scale reuse with little consideration given to decentralized small to medium scale systems. Alternative Water Supply Systems brings together recent research into the available and innovative options and additionally shares experiences from a wide range of contexts from both developed and developing countries. Also covered are the technical, social, financial and institutional aspects associated with decentralized alternative water supply systems. These include systems for greywater recycling, rainwater harvesting, recovery of water through condensation and sewer mining.

"Natural Water Treatment Systems for Safe and Sustainable Water Supply in the Indian Context is based on the work from the Saph Pani project (Hindi word meaning potable water). The book aims to study and improve natural water treatment systems, such as River Bank Filtration (RBF), Managed Aquifer Recharge (MAR), and wetlands in India, building local and European expertise in this field. The project aims to enhance water resources and water supply, particularly in water stressed urban and peri urban areas in different parts of the Indian sub-continent. This project is co-funded by the European Union under the Seventh Framework (FP7) scheme of small or medium scale focused research projects for specific cooperation actions (SICA) dedicated to international cooperation partner countries. Natural Water Treatment Systems for Safe and Sustainable Water Supply in the Indian Context provides: an introduction to the concepts of natural water treatment systems (MAR, RBF, wetlands) at national and international level knowledge of the basics of MAR, RBF and wetlands, methods and hydrogeological characterisation an insight into case studies in India and abroad. This book is a useful resource for teaching at Post Graduate level, for research and professional reference."
