Sustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses. Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to “democratize” membrane filtration have been presented. Riverbank filtration is a “natural” filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.

The issues surrounding water services are some of the most critical challenges facing not only the United States, but also the global community today. The Roundtable on Environmental Health Sciences, Research, and Medicine of the Institute of Medicine convened a workshop in October 2007, summarized in this volume, to address objectives related to Sustainable Water, Sanitation, and Hygiene Services. One of the objectives of the workshop was to think about the interdependence of environmental health and human health as connected through water. Organizations cannot discuss water without considering the interrelationship of sanitation and hygiene. It is the convergence of these strategies that promotes healthy outcomes for both individuals and the environment. A second objective of the workshop was to consider how planning, management, and interdisciplinary approaches-including technology, social behavioral issues, gender, health, environment, economic, and political aspects-can be integrated to arrive at sustainable solutions. Many organizations and agencies are trying to forge a path toward sustainable practices in water, but the various sectors utilizing and governing water services are not interconnected. More integration and a greater understanding of holistic approaches are needed.

The Faculty of Architecture at Delft University of Technology is recognized as one of the most dynamic and innovative research and design schools in Europe and its graduation projects never fail to provide a new angle on design. The Architecture Annual offers a selection of articles charting the school's progress in research and education. This is the second year that The Architecture Annual is themebased: 'Realize' can be regarded in two ways, firstly in the sense of to make real or to accomplish, secondly in the sense of to comprehend or to become aware of. The themes of this and the previous edition ('Architectural Footprints') introduce a duality with regard to the event of 13 May 2008. The physical footprint of the faculty building has vanished: there is now a void where the building once stood in the TU campus. And though this disappearance of the tangible is inevitable, the faculty and the thinking on education there live on. The articles in the present The Architecture Annual make this clear, but sometimes also underline the impact of the fire and the organization of the new permanent accommodation for the faculty. 'Realize' is therefore incorporated in the fairly literal essence of the theme, but also included in a number of papers that bridge the gap between theory and practice and are therefore able to illustrate the research done at the faculty.

Sustainable Investing is fast becoming an essential method of generating long-term returns, moving beyond the negative approaches to socially responsible investing that have dominated the field. This book, our second on the subject, provides over 15 case studies of leading global investors and companies demonstrating how they successfully apply sustainability aspects to their core strategies. Learn from prominent thought leaders Dan Esty and Paul Hawken among others who have contributed key chapters. Our chapter on performance shows clearly how these strategies have been working once negative approaches are parsed out by those examining fund returns. This book also examines in great depth what data exists, and what's on the horizon, to best measure & capture sustainability successfully. Regional perspectives, including 3 chapters on Asia, and focuses on Canada, Australia, Africa & India are also included, as is a look across asset classes. Sustainable Investing, when performed with a positive perspective, has been outperforming the mainstream, unlike negative approaches designed to match benchmark returns. From eco-efficiency to sustainability-driven innovation and beyond, investors of all shapes & sizes need to know how best to position themselves for the radical market shifts underway.
