Africa's water and sanitation infrastructure : access, affordability, and alternatives
The Africa Infrastructure Country Diagnostic (AICD) has produced continent-wide analysis of many aspects of Africa's infrastructure challenge. The main findings were synthesized in a flagship report titled Africa's Infrastructure: a time for transformation, published in November 2009. Meant for policy makers, that report necessarily focused on the high-level conclusions. It attracted widespread media coverage feeding directly into discussions at the 2009 African Union Commission Heads of State Summit on Infrastructure. Although the flagship report served a valuable role in highlighting the main findings of the project, it could not do full justice to the richness of the data collected and technical analysis undertaken. There was clearly a need to make this more detailed material available to a wider audience of infrastructure practitioners. Hence the idea of producing four technical monographs, such as this one, to provide detailed results on each of the major infrastructure sectors, information and communication technologies (ICT), power, transport, and water, as companions to the flagship report. These technical volumes are intended as reference books on each of the infrastructure sectors. They cover all aspects of the AICD project relevant to each sector, including sector performance, gaps in financing and efficiency, and estimates of the need for additional spending on investment, operations, and maintenance. Each volume also comes with a detailed data appendix, providing easy access to all the relevant infrastructure indicators at the country level, which is a resource in and of itself.

Water and climate change adaptation : policies to navigate uncharted waters
This report sets out the challenge for freshwater in a changing climate and provides policy guidance on how to navigate this new “waterscape”. It highlights the range of expected changes in the water cycle and the challenge of making practical, on-site adaptation decisions for water. It offers policymakers a risk-based approach to better “know”, “target” and “manage” water risks and proposes policy guidelines to prioritise action and improve the efficiency, timeliness and equity of adaptation responses.The report also highlights general trends and good practices drawn from the OECD Survey of Policies on Water and Climate Change Adaptation, covering all 34 member countries and the European Commission. Individual country profiles are available, which provide a snapshot of the challenges posed by climate change for freshwater and the emerging policy responses (on-line only).Finally, the report highlights the benefits of well-designed economic instruments (e.g. insurance schemes, water trading, water pricing), ecosystem-based approaches and ‘real options’ approaches to financing. These approaches can improve the flexibility of water policy and investment, reducing the cost of adjusting to changing conditions.

Water, Climate Change, and Sustainability

Climate Change, Water Supply and Sanitation
Climate Change, Water Supply and Sanitation: Risk Assessment, Management, Mitigation and Reduction pulls together the final outcomes and recommendations from the PREPARED project that originated from the WSSTP (Water Supply and Sanitation Technology Platform) thematic working group Sustainable Water Management in Urban areas.
The PREPARED project confirms and demonstrates the technological preparedness of water supply and sanitation systems of ten cities in Europe and also Melbourne and Seattle to adapt to the expected impacts of climate change. It shows that the water supply and sanitation systems of cities and their catchments can adapt and be resilient to the challenges of climate change; and that the technological, managerial and policy adaptation of these PREPARED cities can be cost effective, carbon efficient and exportable to other urban areas within Europe and the rest of the world.
The book: addresses issues related to the management of water, waste water and storm water that are impacted by climate change both in quantitative and qualitative aspects; addresses many of the Pan-European problems and optimises tests and implements adaptive solutions that contribute towards an integrated and coordinated approach; develops adaptation strategies, considering and weighting the mitigation side of solutions to minimise our carbon- and water footprint; improves resilience to deal with the impact of climate change; and contributes to the development of the knowledge base where it concerns the water supply and sanitation sector.

Purified : how recycled sewage is transforming our water
Showing that wastewater has become a surprising weapon in America's war against water scarcity, Annin probes deep into the water reuse movement in five water-strapped states--California, Texas, Virginia, Nevada, and Florida. He drinks beer made from purified sewage, visits communities where purified sewage came to the rescue, and examines how one of the nation's largest wastewater plants hopes to recycle one hundred percent of its wastewater by 2035. At each stop, readers come face to face with the people who are struggling for, and against, recycled water. While the current filtration technology transforms sewage into something akin to distilled water--free of chemicals and safe to drink--water recycling's challenge isn't technology. It's terminology. Concerns about communities being used as \"guinea pigs,\" sensationalist media coverage, and taglines like \"toilet to tap\" have repeatedly crippled water recycling efforts. Potable water recycling has become the hottest frontier in the race for expanded water supply options. But can public opinion turn in time to avoid the worst consequences? Annin's narrative cuts through the fearmongering and misinformation to make the case that recycled water is direly needed in the climate-change era. --From publisher's description.

Decomposition Analysis of Global Water Supply-Demand Balances Focusing on Food Production and Consumption
Food production and consumption require large amounts of freshwater. There is no literature on the decomposition analysis of the intensities of water supply-demand balances (water balance intensities) for each country worldwide. The aim of this study is to evaluate the water balance intensities and elucidate the promoting factors and offset factors of water balance intensities for each country worldwide, focusing on food supply-demand balances and considering food trade balances on a global scale. The modified Laspeyres index method is applied to both a production-based water balance index (WBIPB) and a consumption-based water balance index (WBICB). The major promoting factor for the WBIPB is the renewable freshwater resources, whereas the major offset factor is the produced item preference. The major promoting factor for the WBICB is the consumed item preference, whereas the major offset factor is the producing area preference. Improving irrigation efficiencies of rice and cereals is effective because rice requires the largest blue water footprint intensities, considering irrigation efficiency on a calorie content basis in all of the items, whereas cereals are the largest share of calorie-based production quantities in all of the items worldwide. This study provides the foundation for decreasing water balance intensities regarding food production and consumption.
