This book was released on 2011-08-28 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of water in our communities, from local to regional and right up to global levels, poses a series of key questions about climate change, about the anthropogenic impact on the environment, and about all the interconnected actions and events that affect the availability and quality of the resource. All these questions share a common demand for more scientific knowledge and information. In this particular context the disciplinary boundaries are fading, and there is a growing need to create broader connections and wider collaborative interdisciplinary groups, aimed at building an integrated knowledge-base to serve not only stakeholders but also the whole of society. Only in this way can we hope to respond effectively to the challenges and changing dynamics of human-hydrologic systems. Following this concept, contributors from multiple disciplinary backgrounds, such as Law Studies, Hydrogeology, Monitoring and Information Technologies, Geophysics, Geochemistry, Environmental Sciences, Systems Engineering, Economics and Social Studies, joined forces and interacted in this workshop. The present book reports the proceedings of this three-day ARW (Advanced Research Workshop), and explores different aspects of the environmental security assessment process, focusing on the assessment, monitoring and management of water resources, and giving an overview of the related scientific knowledge.

Book excerpt: Global Groundwater: Source, Scarcity, Sustainability, Security, and Solutions presents a compilation of compelling insights into groundwater scenarios within all groundwater-stressed regions across the world. Thematic sub-sections include groundwater studies on sources, scarcity, sustainability, security, and solutions. The chapters in these sub-sections provide unique knowledge on groundwater for scientists, planners, and policymakers, and are written by leading global experts and researchers. Global Groundwater: Source, Scarcity, Sustainability, Security, and Solutions provides a unique, unparalleled opportunity to integrate the knowledge on groundwater, ranging from availability to pollution, nation-level groundwater management to transboundary aquifer governance, and global-scale review to local-scale case-studies. - Provides interdisciplinary content that bridges the knowledge from groundwater sources to solutions and sustainability, from science to policy, from technology to clean water and food - Includes global and regional reviews and case studies, building a bridge between broad reviews of groundwater-related issues by domain experts as well as detailed case studies by researchers - Identifies pathways for transforming knowledge to policy and governance of groundwater security and sustainability

Available in PDF, EPUB and Kindle. Book excerpt: This book celebrates the relaunch of the African Pollen Database, presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa, and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e.g. abundance of forests vs. grasslands), provide insights into changes in biodiversity, and gain empirical evidence of vegetation response to climatic change and human activity. In this, the 35th Volume of "Palaeoecology of Africa", we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution, human activity, climate change and vegetation dynamics during the Quaternary, the last 2.6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles), human evolution, and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states, identify the drivers of vegetation change, and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i.e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past), and (ii) the past is the key to the future (i.e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological, environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western, eastern, central, and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change), as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore, it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future.
