Book Description
Dr. Albert Schmid President of the Federal Office for Migration and Refugees According to the United Nations, about 200 million people of the estimated world population of 6.8 billion are international migrants – that corresponds to about three per cent of the total world population. The proportion of international migrants in the global population has increased only marginally in the last 40 years. But, as a result of global population growth, the absolute number of migrants has increased, and their structure and spatial distribution has changed considerably. A structural shift has taken place primarily in the industrialised countries, where less than 20 per cent of the global workers are now living, but where more than 60 per cent of all migrants worldwide reside. Since 1990, more than 16 million people have moved to Germany, while about 11 million have left the country in the same period. Altogether, 15 million people of international migration origin are living in Germany, comprising almost 19 per cent of Germany’s current population of 82 million. At the end of 2006, about 64 million people out of Europe’s population of 732 million, or nine per cent, lived in a European country they were not born in. But why does anybody migrate at all? People decide to leave because, in general, they expect to find better conditions and opportunities in other countries or regions.

Book Description
This volume provides the technical information required for the production of biofuels and chemicals from lignocellulosic biomass. It starts with a brief overview of the importance, applications, and production processes of different lignocellulosic products. Further chapters review the perspectives of waste-based biofuels and biochemicals; the pretreatment of lignocellulosic biomass for biofuel production; cellulolytic enzyme systems for the hydrolysis of lignocelluloses; and basic and applied aspects of the production of bioethanol, biogas, biohydrogen, and biobutanol from lignocelluloses. This book is recommended for researchers and engineers and particularly students taking biofuel courses at graduate level.

Book Description
Over the last decades, scientists have been intrigued by the fascinating organisms that inhabit extreme environments. These organisms, known as extremophiles, thrive in habitats which for other terrestrial life-forms are intolerably hostile or even lethal. Based on such technological advances, the study of extremophiles has provided, over the last few years, ground-breaking discoveries that challenge the paradigms of modern biology. In the new bioeconomy, fungi in general, play a very important role in addressing major global challenges, being instrumental for improved resource efficiency, making renewable substitutes for products from fossil resources, upgrading waste streams to valuable food and feed ingredients, counteracting life-style diseases and antibiotic resistance through strengthening the gut biota, making crop plants more robust to survive climate change conditions, and functioning as host organisms for production of new biological drugs. This range of new uses of fungi all stand on the shoulders of the efforts of mycologists over generations. The book is organized in five parts: (I) Biodiversity, Ecology, Genetics and Physiology of Extremophilic Fungi, (II) Biosynthesis of Novel Biomolecules and Extremozymes (III) Bioenergy and Biofuel synthesis, and (IV) Wastewater and biosolids treatment, and (V) Bioremediation.

Book Description
Secretions and emissions in biological systems play important signaling roles within the organism but also in its communications with the surrounding environment. This volume brings together state-of-the-art information on the role of secretions and emissions in different organs and organisms ranging from flowers and roots of plants to nematodes and human organs. The plant chapters relate information regarding the biochemistry of flower volatiles and root exudates, and their role in attracting pollinators and soil microbial communities respectively. Microbial chapters explain the biochemistry and ecology of quorum sensing and how microbial communities highly co-adapted to plants can aid in bio-energy applications by degrading ligno-cellulosic materials. Other chapters explain the biology of secretions by nematodes, algae and humans, among other organisms. This volume will be a welcome addition to the literature, as no other book covers aspects related to biological secretion in such a holistic and integrative manner.

Book Description
Analysing and synthesising vast data sets from a multitude of disciplines including climate science, economics, hydrology and agricultural research, this volume seeks new methods of combining climate change mitigation, adaptation, development, and poverty reduction in ways that are effective, efficient and equitable. A guiding principle of the project is that new alliances of state and non-state sector partners are urgently required to establish cooperative responses to the threats posed by climate change. This volume offers a vital policy framework for linking our response to this change with progressive principles of global justice and sustainable development.
