Integrated Water Resources Management in Water-scarce Regions consolidates the transdisciplinary research of the project “CuveWaters: Integrated Water Resources Management in Central Northern Namibia (Cuvelai Basin) in the SADC-Region” funded by the German Federal Ministry for Education and Research (BMBF) and undertaken from 2004 to 2015 in Namibia. In these eleven years it was possible to accomplish all three phases of an ideal-typical transdisciplinary research process, from creating a common research object down to transdisciplinary dissemination. The transdisciplinary research approach was designed to tackle the life-world problems of food security, sanitation and access to water in a sustainable way. It aimed at integrating science, technology and society with the common goal of establishing a multi-resource mix for water use to improve the living conditions of people in the project region. This ‘multi-resource mix’ comprises water from different sources made available through adapted technological solutions which are socially embedded. The technological solutions identified with the Namibian partners were rainwater and floodwater harvesting, groundwater desalination, sanitation and water reuse. Each technological solution is reflected in terms of approach, technology, social aspects, management and governance issues, economic viability and sustainability evaluation. This book shows how technological innovation must go hand in hand with social innovation regarding knowledge, practices and institutions. A comprehensive report of the design, methodologies and procedures as well as the research findings and conclusions is provided here. The aim of this book is to share with researchers, professionals and practitioners the lessons learned during the project and provide guidance for replication.

Rainwater as a resource has been underrated due to scientific misunderstandings about its quality, the lack of hydrologic design tools for small catchments, such as roofs, the preference for large infrastructures, and the small number of successful cases reported. This book summarizes seventeen years of scientific research, operational monitoring, and practical demonstration projects made at Seoul National University Rainwater Research Center.A new paradigm of rainwater is proposed, which is to collect rainwater and use it, instead of draining it. Based on conventional hydrology and methodology, a hydrological modelling method for micro-catchment is suggested. By incorporating several controllable measures into the design, the system can solve several water-related problems such as flooding, water conservation, emergency water storage, and groundwater recharge.Now is the time to adapt. Many good examples are reported from around the world, including South Korea. Fifty-nine South Korean cities have announced regulations and commitment to become "Rain Cities" by offering financial incentives to rainwater management systems or subsidizing them.This book is written to give hope to those who seek to transform their community from a "Drain City" to a "Rain City". It has been prepared to clear the ambiguity about rainwater management and transform the experts as well as the citizens to become active proponents of rainwater. This book can be a guide to transform the world into Rain Cities, and become a viable solution toward Sustainable Development Goal Number 6.ISBN: 9781780408705 (Paperback)ISBN: 9781780408712 (eBook)ISBN: 9781780409351 (ePub)
Plus d'un milliard de personnes dans les zones urbaines et périurbaines d'Afrique, d'Asie et d'Amérique latine sont desservies par des dispositifs d'assainissement à la parcelle. La gestion des boues extraites de ces dispositifs, les « boues de vidange », a été jusqu'à présent grandement négligée. Les ressources financières sont souvent insuffisantes et les dispositifs d'assainissement à la parcelle ont tendance à être considérés comme des solutions temporaires, dan l'attente de la mise en place de réseaux d'égouts. Cependant , force est de constater que l'assainissement à la parcelle est là pour durer, soit en tant que solution autonome permanente, soit en association avec des systèmes égouts-station. La gestion adéquate des boues de vidange issues des dispositifs d'assainissement des ménages est un impératif pour la protection de Ia santé humaine et de l'environnement.Cet ouvrage est le premier à être consacré à la gestion des boues de vidange. II rassemble l'état actuel des connaissances de ce domaine qui évolue rapidement, et propose une approche intégrée qui lie les composantes technologiques, organisationnelles et de planification. II aborde la planification et l'organisation de l'ensemble de la filière de gestion des boues de vidange depuis la collecte et l'évacuation des boues jusqu'aux solutions de traitement et à l'utilisation finale ou la mise en dépôt des boues traitées. En plus de fournir des éléments fondamentaux sur le traitement et une description des technologies existantes, l'ouvrage présente en détail les aspects opérationnels, institutionnels et financiers. II propose également une méthode de planification d'un projet de gestion des boues de vidange à l'échelle d'une ville avec l'ensemble des parties prenantes.ISBN: 9781780409795 (Print)ISBN: 9781780409801 (eBook)
The supply of healthy drinking water and disposal of our wastewater is a central problem. Solving this problem is one of the claims of the UN Millennium Development Goals, and consequently an obligation for all those involved with water to join efforts in finding solutions. Climate change, population growth, migration and urban sprawl are factors forcing us to reconsider the traditional approach to urban water management. The water supply and sanitation infrastructure currently in use worldwide was developed in and for countries which are relatively wealthy, and which have access to plenty of water. Is it really wise to build the same kind of infrastructure and to apply the same methods and processes in regions with different climatic, ecological and economical conditions? Should we maintain our flush and discharge sanitation concepts while freshwater is becoming a limited resource? Aren't there smarter more environmentally sound methods to use and safegaurd our precious water resources? Are water authorities, city planners, architects, regulators and politicians ready to accept innovative solutions deviating from those described in textbooks? Questions like these were raised during the International Symposium Water Supply and Sanitation for All held in Berching, Germany from September 27 - 28, 2007. This book collects the papers presented at this conference.ISBN: 9781780409986 (eBook)
Anaerobic digestion is one of the most active IWA Specialist Groups, with over 1000 members, active sponsorship of three task groups or working groups, and organisation of on average, one Specialist Group conference per year.This is highlighted by our recent World Conference -AD14 in Viña del Mar, where over 750 delegates attended, and 200 papers and 441 posters were presented.The themes at the Anaerobic digestion conferences provide a very good review of major themes of interest in anaerobic digestion.Over the years, we have always observed a large number of papers focusing on specific aspects related to the themes of (1) solid waste and energy crop management; (2) biosolids and sludge management; (3) industrial wastewater.These application areas have been strongly supported by investigation into microbial ecology, mathematical modelling, chemical analysis, process innovations and novel technologies.Over the past 5 years though, we have seen several major new themes emerge.These have been driven by both market opportunities and scientific advances.The goal of this review is to further outline challenges and opportunities for wastewater treatment researchers and practitioners in these areas, as well as the specific role of anaerobic digestion technologies within these application areas.
