Riverine Ecosystem Management
This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this.

The Alte Donau: Successful Restoration and Sustainable Management
Here we report on a 25-year long-term sequence of measures to return a deteriorated recreational urban lake, Alte Donau in Vienna to acceptable water quality. Metropolitan waters require focused ecosystem management plans and intensive in-lake efforts. We explored physico-chemical conditions, food web from viruses to fish and water birds, the sediments, the littoral zone and the catchment, management and urban planning, and global warming. Several restoration techniques were tested and critically evaluated. The final management plan was based on bi-stable theory. During the recovery phase, numerous surplus adjustments had to be implemented to secure sustainable achievement.
Social and Ecological System Dynamics
This book is a social—ecological system description and feedback analysis of the Lake Tana Basin, the headwater catchment of the Upper Blue Nile River. This basin is an important local, national, and international resource, and concern about its sustainable development is growing at many levels. Lake Tana Basin outflows of water, sediments, nutrients, and contaminants affect water that flows downstream in the Blue Nile across international boundaries into the Nile River; the lake and surrounding land have recently been proposed as a UNESCO Biosphere Reserve; the basin has been designated as a key national economic growth corridor in the Ethiopian Growth and Transformation Plan. In spite of the Lake Tana Basin’s importance, there is no comprehensive, integrated, system-wide description of its characteristics and dynamics that can serve as a basis for its sustainable development. This book presents both the social and ecological characteristics of the region and an integrated, system-wide perspective of the feedback links that shape social and ecological change in the basin. Finally, it summarizes key research needs for sustainable development.
Österreichs Donau
Der heutige Zustand der Donau, ihrer Landschaften und ihrer Fischfauna ist das Resultat vieler menschlicher Eingriffe. Diese passierten teils erst in den letzten Jahrzehnten, manche reichen aber auch Jahrhunderte zurück. Mit dem neuen Buch „Österreichs Donau. Landschaft – Fisch – Geschichte“ gehen die Autoren/in der spannenden Frage nach, wie sich das Ökosystem der Donau und ihrer Auen im Laufe der Zeit verändert hat und wie es in der Zukunft weitergehen kann. Dabei werden nicht nur die vielfältigen Eingriffe in Form von Regulierungen, Kraftwerkserrichtungen und deren Auswirkungen auf die Fischfauna beschrieben, sondern auch die geologische und fischökologische Entwicklung im gesamten Einzugsgebiet der Donau. Bisher umgesetzte Revitalisierungsmaßnahmen und Vorschläge für eine umfassende ökologische Verbesserung der Flusslandschaft mit den Menschen als Teil des Donaulebensraumes zeigen das zukünftige Potenzial dieses großen europäischen Stromes. Umfangreiche Illustrationen mit alten Stichen, historischen Karten und aktuellen Fotos bereichern das Buch.
Ökosystem Wien
Wien bemüht sich zu Recht, eine 'grüne Musterstadt' zu werden. Von ihren natürlichen Voraussetzungen her ist diese Stadt in einzigartiger Weise begünstigt wie kaum eine andere europäische Metropole. Gelegen am Schnittpunkt mehrerer Großlandschaften, hat sich der Wiener Raum zu einer Drehscheibe von Faunen und Floren aus Süd und Nord, West und Ost entwickelt. Das Hauptanliegen von 'Ökosystem Wien - Naturgeschichte einer Stadt' ist es, die Kräfte und Zusammenhänge anschaulich zu machen, die seit Jahrtausenden zu der ökologischen Sonderstellung dieser Stadt geführt haben. Zugleich soll der Blick geöffnet werden für die unterschiedlichen Landschaften und Ökosysteme, die hier aufeinandertreffen. Zu sehen, was vor den Augen liegt, ist eine in der urbanen Gesellschaft nicht selbstverständliche Fähigkeit. Sie ist heute jedoch notwendiger denn je, wenn wir das einzigartige Naturerbe des Wiener Raumes erhalten wollen.
Kenya's Engagement with China
In recent decades, Kenya has witnessed profound changes in its economic, cultural, and environmental landscapes resulting from its interactions with China. University students are competing for scholarships to study in China, coastal artisanal fishers are increasingly worried about Chinese-owned trawlers depleting fish stocks, fishers on Lake Victoria are grappling with the impact of frozen tilapia from China, and unemployed youth are seeking a fair shot at working on one of Kenya’s multimillion-dollar Chinese-funded infrastructure projects. Anita Plummer’s Kenya’s Engagement with China investigates the tension between official Kenyan and Chinese state narratives and individual Kenyans’ reactions to China’s presence to provide insight into how everyday Kenyans exercise their political agency. The competing discourses Plummer uncovers in person, in the news, and online reveal how Kenyans use China to question local power structures, demand policy change, and articulate different visions for their country’s future. This critical text represents the next step in research on Sino-African relations.
APPEAR II
This book is an ambitious undertaking – a research documentation that describes a wide variety of approaches to knowledge production relevant to development policy, and illustrates the diverse possibilities of transdisciplinary development research within 25 projects in 15 countries. The editor encouraged the 105 authors – 46 female, 59 male – to investigate questions, problems and dimensions of knowledge production that are usually not addressed in research and project reports. Project planning, no matter how successful, can only partially anticipate the social reality of implementing a project. Flexibility, creativity and improvisation are indispensable prerequisites for successful project implementation in often difficult research conditions. Thus, this book is not only a documentation of the second phase of the Austrian Partnership Programme in Higher Education and Research for Development – APPEAR – but also a discursive contribution on practical approaches to transdisciplinary and transcultural knowledge production.
