Studienarbeit aus dem Jahr 2011 im Fachbereich Geowissenschaften / Geographie - Allgemeines, Grundlagen, Note: 2.1, Christian-Albrechts-Universität Kiel, Sprache: Deutsch, Abstract: Diese Arbeit setzt sich mit dem Thema der Wasserknappheit als Folge des Klimawandels auseinander. Wie bereits der UN-Generalsekretär Ban Ki-Moon im Jahr 2008 feststellte, ist das Problem der Versorgung der Bevölkerung mit Wasser, welches qualitativ und quantitativ den Ansprüchen genügt, eine der größten Herausforderungen der Menschheit. Schon gegenwärtig leiden ein Drittel der weltweiten Bevölkerung unter dem Problem des Wassermangels. In Anbetracht der Tatsache, dass der Klimawandel diese Herausforderung in einigen Regionen der Welt verstärken wird und zwei Drittel der weltweiten Bevölkerung unter dem Problem der Wasserarmut leiden werden, erscheint es von großer Wichtigkeit, dieser Aufgabe in Zukunft gewachsen zu sein. Es wird die Bedeutung von Wasser in der heutigen Gesellschaft und des hydrologischen Kreislaufs thematisiert. Dieser bedingt die globale Verteilung von Wasserknappheit und Wasserüberschuss entscheidend. Auch die Unterscheidung zwischen Wasserknappheit im privaten Bereich und in der Landwirtschaft wird in den Blick genommen. Als eine mögliche Gegenmaßnahme einer solchen Eskalation wird die Funktionalität eines effektives Wassermanagement beleuchtet. Als Beispiel für die Erläuterung der konkreten Wassersituation dient Ägypten.

„Jahrhundertdürre in Australien“, „Die Flüsse trocknen aus“, „Die Grundwasservorräte schwinden“: Eine Ära weltumspannender Wasserknappheit scheint angebrochen zu sein. Wasserkrisen gehören mittlerweile zu den größten globalen Risiken für Wirtschaft und Gesellschaft, Zusammenhänge mit Nahrungsmittelknappheit und mangelnder Anpassung an den Klimawandel sind offenkundig. Der Autor, Experte des weltweit renommierten Potsdam-Instituts für Klimafolgenforschung (PIK), analysiert die globale Wasserkrise vor dem Hintergrund des Klimawandels und einer weiter steigenden Nachfrage nach Lebensmitteln. Er zeigt, dass Wasserknappheit selten die unabwendbare Folge schwindender Wasservorräte ist, sondern immer auch das Resultat der (unverhältnismäßig hohen) Nachfrage durch den Menschen. Von Anbeginn an hat die Menschheit einen überwältigenden Erfindungsreichtum an den Tag gelegt, Wasser zu bewirtschaften und aus immer ferneren Gegenden heranzuziehen. Heute benötigen wir ein neues Wasserethos: Es respektiert die durch lokale und planetare Umweltbedingungen gesetzten Grenzen und überführt die Gewässerökosysteme wieder in einen intakten Zustand. Es umfasst darüber hinaus den gerechten Zugang aller Menschen zu sauberem Wasser, arbeitet also auch an der Abschaffung der globalen Wasserverteilungs- und Wasserqualitätskrise.

Beyond Interdisciplinarity examines the broadening meaning of core concept across academic disciplines and other forms of knowledge. In this book, Associate Editor of The Oxford Handbook of Interdisciplinarity and internationally recognized scholar Julie Thompson Klein depicts the heterogeneity and boundary work of inter- and trans-disciplinarity in a conceptual framework based on an ecology of spatializing practices in transaction spaces, including trading zones and communities of practice. The book includes both "crossdisciplinary" work (encompassing multi-, inter-, and trans-disciplinary forms) as well as "cross-sector" work (spanning disciplines, fields, professions, government and industry, and communities). The first section of the book defines and explains boundary work, discourses of interdisciplinarity, and the nature of interdisciplinary fields. In the second section, Klein examines dynamics of working across disciplines, including communication, collaboration, and learning with concrete examples and lessons from research projects and programs that transcend traditional fields. The closing chapter examines reasons for failure and success then presents gateways to literature and other resources. Throughout the book, Klein emphasizes the roles of contextualization and historical change while factoring in the shifting relationship of disciplinarity and interdisciplinarity, ascendancy of transdisciplinarity, and intersections with other constructs including Mode 2 knowledge production, convergence, team science, and postdisciplinarity. The conceptual framework she provides also includes the role of boundary objects, agents, and organizations in brokering differences and creating for platforms for change. Klein further explains why translation, interlanguage, and a communication boundary space are vital to achieving intersubjectivity and collective identity. They foster not only pragmatics of negotiation and integration but also reflexivity, transactivity, and co-production of knowledge with stakeholders beyond the academy. Rhetorics of holism and synthesis compete with instrumentalities of problem solving and transgressive critiques. However, typical warrants today include complexity, contextualization, collaboration, and socially-robust knowledge. Crossing boundaries remains complex, but this book guides readers through the density of pertinent literature while expanding understandings of crossdisciplinary and cross-sector work.

Recent years have witnessed growing interest in a series of issues related to migration, including identity formation and change, the role of social capital and social networks, ethnic discrimination, racism and xenophobia, socio-political participation and mobilisation and the complex nature of the causal mechanisms linked to migration – issues that are better highlighted and investigated using qualitative methods. Moving away from the quantitative and empiricist-positivist approaches that have often characterised migration research, Qualitative Methods in Migration Studies explores in a concise but comprehensive way the key issues involved in researching migratory phenomena in a qualitative manner. It addresses themes including the basic characteristics of contemporary migration, qualitative research into social processes related to migration, and the relationship between theory, research design and practice. Drawing upon empirical case studies and a series of real and hypothetical examples, the book develops a critical realist alternative both to empiricism and interpretivist, social constructionist and post-structuralist relativism in qualitative migration research. With special emphasis on the meta-theoretical dimensions of qualitative research practice, this volume connects qualitative findings to policy formation and ‘politics making’, exploring the multiple dimensions involved in researching migratory phenomena, such as ontology, epistemology, methodology, ethics and research practice. As such, it will be of interest to students and researchers in migration across the social sciences.

Malnutrition caused by deficiencies of vitamins and minerals - also called hidden hunger - impairs both the intellectual and physical development of a child. Due to the absence of clinical symptoms and assessments, no intervention can be staged. The tragedy is that this, in turn, decreases the child’s chance to escape from poverty. This book looks at malnutrition in high-income countries, the nutrition transition and nutritional deficiencies in low-income countries, consequences of hidden hunger, and interventions to improve nutrition security. Written by leading experts in the field, it clearly stresses that national governments and international organizations must make malnutrition one of their top priorities in order to provide children with optimal conditions for a healthy future.

Water Reuse: An International Survey of current practice, issues and needs examines water reuse practices around the world from different perspectives. The objective is to show how differently wastewater reuse is conceived and practised around the world as well as to present the varied needs and possibilities for reusing wastewater. In the first section water reuse practices around the world are described for regions having common water availability, reuse needs and social aspects. The second section refers to the “stakeholders” point of view. Each reuse purpose demands different water quality, not only to protect health and the environment but also to fulfil the requirements of the specific reuse. Reuses considered are agricultural, urban agriculture as a special case of the former, municipal and industrial. Alongside these uses, the indirect reuse for human consumption through aquifer recharge is also discussed. The third section deals with emerging and controversial topics. Ethical and economical dilemmas in the field are presented as a subject not frequently addressed in this field. The role of governments in respect of public policy in reuse is discussed as well as the different international criteria and standards for reusing wastewater. The importance of public acceptance and the way to properly handle it is also considered. The fourth section of the book presents contrasting case studies; typical situations in the developed world (Japan and Germany) are compared to those in developing countries (Pakistan and Brazil) for agricultural and industrial reuse. Indirect planned reuse for human consumption (Germany) is compared with an unplanned one (Mexico). The Windhoek, Namibia case study is presented to emphasize why if the direct reuse of wastewater for human consumption has been performed with success for more than 35 years it is still the only example of this type around the world. To illustrate the difficulties of having a common framework for regulating water reuse in several countries, the Mediterranean situation is described. Other case studies presented refer to the reuse situation in Israel, Spain, Cameroon, Nepal and Vietnam, these latter countries being located in water rich areas. This book will be an invaluable information source for all those concerned with water reuse including water utility managers, wastewater policy makers and water resources planners as well as researchers and students in environmental engineering, water resources planning and sanitary engineering.

This book about the Mekong Delta presents a unique collection of state-of-the-art contributions by international experts from different scientific disciplines about the characteristics and pressing water-related challenges of the Mekong Delta in Vietnam. The Mekong Delta belongs to one of the areas, which are to expect the largest challenges concerning environmental change and climate change induced sea level rise . The Delta acts as the “rice bowl” of Southeast Asia and is home to over 17 Million people, who need to cope with ecologic as well as socio-economic changes linked to the rapid economic development of the country. Annual floods, severe droughts, salt water intrusion, degrading water quality, tropical cyclones, hydrologic changes due to hydropower projects in the upstream of the Mekong, coastal erosion, and the loss of biodiversity are some of the problems in the region. Heterogeneous resource management responsibilities, and the fact that the Mekong – and thus also the Delta – is influenced by six countries aggravate the situation. Integrated water resources management and fostered cooperation and information exchange are pressing needs for the sustainable development of the Delta.
