        Conflict, Social Capital and Managing Natural Resources

        A West African Case Study

        by Edited by Keith M Moore

        This book is the product of a six-year multi-disciplinary collaborative research program in sustainable agriculture and natural resource management. It describes the transition of the conflict-ridden agricultural and pastoral systems of arid and semi-arid regions of West Africa to more intensified agricultural and animal husbandry systems. The research investigates technological options and decision tools and explores a replicable methodology for building social capital within a rural community in the Inland Delta of the Niger River. The chapters recount the efforts of researchers and development agents to identify new approaches for sustainable development and the experiences of the local population seeking a pathway from poverty and food insecurity to a healthy economy and environment.

        Große Fuge

        by Volker Braun

        »Was haben Sie 2020 gemacht?« In dem Jahr, in dem die Welt »bewegt ist, miteinmal, stillezustehn«. Als die Straßen »entmenscht« sind, die Stadt ruhiggestellt ist und »die Logik der Rettung« lautet: »Nicht vor Publikum, nicht in dieser Saison«. Während »Wetterwandel« und »Weltenaufruhr« andernorts weitertoben: Im Anthropozän findet der Mekong sein Delta nicht mehr, fressen sich Brände in den trockenen Wald, herrscht ein »Krieg der Landschaften«. Und inmitten all dessen wir – der so moderne, aber doch vergängliche Mensch, der »Mensch der Katastrophe«, zu allem fähig, im Guten wie im Schlechten, stets menschlich. Die neuen Gedichte von Volker Braun vermessen eine Welt, einen Alltag im Wandel. Immer politisch, immer sozial zeigt sich der Mensch in diesem Dazwischen. Und kann sich – trotz allen Fortschritts – die Natur am Ende doch nicht unterwerfen. Aber im ewigen Werden und Vergehen liegt auch ein gewisser Trost.

        New Land, New Life

        A success story of new land resettlement in Bangladesh

        by Andrew Jenkins, Natasha Haider, Bazlul Karim, Mihir Kumar Chakraborty, Kiran Sankar Sarker, Rezaul Karim, Robiul Islam, Nujulee Begum, Edward Mallorie, Koen de Wilde

        The Ganges-Brahmaputra-Meghna delta has newly emerged 'char' islands, resulting from the deposition of sediment, which are very vulnerable, socially, institutionally and environmentally. This book explains how the governments of Bangladesh and the Netherlands and the International Fund for Agricultural Development cooperated on a land-based rural development project to give settlers security and purpose. It details how they engaged communities and civil societies, and implemented an infrastructure aimed at reducing flooding, improving drainage, and providing adequate drinking water and sanitation. The book describes the project's application to crop and animal agriculture, and the development of value chains and encouragement of female participation. It considers the financial underpinning and infrastructure, as well as how to ensure the impacts of the scheme are enduring. The scheme serves as a model for support projects to vulnerable groups faced with climate change and other environmental challenges. This book is suitable for students, researchers, specialists and practitioners in rural development, water resources, land management and soil science.

        Grass Genera of the World

        by Leslie Watson, Michael J Dallwitz

        Modern taxonomic treatments of the grass family (Poaceae, Gramineae) recognize about 10,000 species and as many as 785 genera. This book provides detailed descriptions of these genera, in alphabetical sequence, the descriptions having been generated by computer from a taxonomic data bank. One of the authors has been engaged for some twenty years in compiling data and observations on grass genera, in order to investigate classificatory questions and to explore taxonomic applications of computer methods. The other has worked for a similar time on computer key-making, and has developed the DELTA system for comprehensive representation and manipulation of taxonomic descriptions. They have devised a grass generic character list to cover all aspects of variation in glasses. In this book this list comprises 496 characters, dealing with nomenclature, general morphology, leaf anatomy and physiology, biochemistry, haploid and 2cDNA values, fruit and embryo structure, seeding form, cytology, intergeneric hybrids, phytogeography and distribution, ecology, pathogens, classification and economic aspects. The work is undoubtedly a definitive work, essential for all those with a serious research interest in grasses.

        Viruses of Plants

        by Alan A Brunt, Karen Crabtree, Michael J Dallwitz, Adrian Gibbs, Leslie Watson

        This book is a product of the international VIDE (Virus Identification Data Exchange) project, which uses the DELTA (Description Language for Taxonomy) database system to collect diagnostic information on all plant viruses. Information on over 500 characters has been sought for each virus and stored in the VIDE database. Over two-thirds of these characters record the susceptibility, or otherwise, of a range of commonly used test plant species; the remainder represent the great range of other characters used for virus identification. Information on the known natural host range of each virus is also presented. The book covers more than 900 viruses, which represents the entire database of plant viruses from around the world. It includes all viruses of plants, not only those whose virions have been described, but also those such as umbraviruses that have no virion protein genes of their own, and use the virion proteins of their symbiotic helper viruses. Viroids and the many transmissible agents that cause virus-like diseases, but whose infectious particles have not yet been characterized, are excluded. However, the database accession numbers of the genomic sequences of satellite RNAs are included. The book also contains summaries of data for all the viruses that are definitive or tentative members of the 50 or so accepted genera or "groups". Overall, the book is a standard reference work that will prove indispensable for virologists ad plant pathologists.

        Threatcon Delta

        Assault on the Pentagon

        by David Alexander

        Threatcon Delta: Assault on the Pentagon tells the story of how terrorism, treason and global organized crime converge to place the most potent symbol of American military power under the control of a determined and ruthless group of heavily armed and extremely dangerous men who can’t be stopped, yet who must be stopped. This global superthriller is based both on author David Alexander’s extensive and detailed research into the history of the Pentagon, combined with first-hand knowledge of the Pentagon's most closely held secrets by this veteran defense insider, all of which has been artfully woven into a masterpiece of high-concept suspense fiction. In fact, the combined impact of accuracy and authenticity blended with superb storytelling may find some readers asking themselves if perhaps some parts of the story shouldn't have been made public, for fear that terrorists or global criminals might some day use it as a basis for an actual plan of attack. Yet the assault on the Pentagon portrayed in the book is no standard terrorist martyrdom mission either. Those who’ve taken over the headquarters of the United States military have an exit strategy that has been brilliantly devised to shuttle them to safety and provide for the enjoyment of their ill-gotten profits -- a scam on a global scale that promises to net the Building’s hijackers a considerable fortune. By any standard, Threatcon Delta: Assault on the Pentagon is action thriller fiction at its boldest and best. It’s one of the achievements that have earned David Alexander a secure place at the top of the list of the world’s masters of the game.

        Sustainable Water and Environmental Management in the California Bay-Delta

        by Committee on Sustainable Water and Environmental Management in the California Bay-Delta; Water Science and Technology Board; Ocean Studies Board; Division on Earth and Life Studies; National Research Council

        Extensively modified over the last century and a half, California's San Francisco Bay Delta Estuary remains biologically diverse and functions as a central element in California's water supply system. Uncertainties about the future, actions taken under the federal Endangered Species Act (ESA) and companion California statues, and lawsuits have led to conflict concerning the timing and amount of water that can be diverted from the Delta for agriculture, municipal, and industrial purposes and concerning how much water is needed to protect the Delta ecosystem and its component species. Sustainable Water and Environmental Management in the California Bay-Delta focuses on scientific questions, assumptions, and conclusions underlying water-management alternatives and reviews the initial public draft of the Bay Delta Conservation Plan in terms of adequacy of its use of science and adaptive management. In addition, this report identifies the factors that may be contributing to the decline of federally listed species, recommend future water-supple and delivery options that reflect proper consideration of climate change and compatibility with objectives of maintaining a sustainable Bay-Delta ecosystem, advises what degree of restoration of the Delta system is likely to be attainable, and provides metrics that can be used by resource managers to measure progress toward restoration goals.

        A Review of the Use of Science and Adaptive Management in California's Draft Bay Delta Conservation Plan

        by Panel to Review California's Draft Bay Delta Conservation Plan; Water Science and Technology Board; Ocean Studies Board; Division on Earth and Life Studies; National Research Council

        The San Francisco Bay Delta Estuary is a large, complex estuarine ecosystem in California. It has been substantially altered by dikes, levees, channelization, pumps, human development, introduced species, dams on its tributary streams and contaminants. The Delta supplies water from the state's wetter northern regions to the drier southern regions and also serves as habitat for many species, some of which are threatened and endangered. The restoration of water exacerbated tensions over water allocation in recent years, and have led to various attempts to develop comprehensive plans to provide reliable water supplies and to protect the ecosystem. One of these plans is the Bay Delta Conservation Plan (BDCP). The report, A Review of the Use of Science and Adaptive Management in California's Draft Bay Delta Conservation Plan, determines that the plan is incomplete in a number of important areas and takes this opportunity to identify key scientific and structural gaps that, if addressed, could lead to a more successful and comprehensive final BDCP. The plan is missing the type of structure usually associated with current planning methods in which the goals and objectives are specified, alternative measure for achieving the objectives are introduced and analyzed, and a course of action in identified based on analytical optimization of economic, social, and environmental factors. Yet the panel underscores the importance of a credible and a robust BDCP in addressing the various water management problems that beset the Delta. A stronger, more complete, and more scientifically credible BDCP that effectively integrates and utilizes science could indeed pave the way toward the next generation of solutions to California's chronic water problems.

        Delta Waters

        Research to Support Integrated Water and Environmental Management in the Lower Mississippi River

        by Committee on Strategic Research for Integrated Water Resources Management; Water Science and Technology Board; Division on Earth and Life Studies; National Research Council

        The Water Institute of the Gulf is a not-for-profit, independent research institute dedicated to advancing the understanding of coastal, deltaic, river and water resource systems, both within the Gulf Coast and around the world. Their mission supports the practical application of innovative science and engineering, providing solutions that benefit society. Those who make policy for coastal and deltaic systems, as well as managers of natural resources, need high-quality science and engineering to guide their decisions. The Water Institute of the Gulf began operations in 2012 to address exactly this sort of challenge. Delta Waters offers advice to The Water Institute of the Gulf that it might use as part of its strategic planning process. This report focuses on strategic research to support integrated water resources management in the lower Mississippi River delta and includes international comparative assessments. The recommendations of Delta Waters promote a human and environmental systems approach to scientific research that supports integrated water and environmental resources management in the lower Mississippi River and delta, and offers ideas regarding comparative assessments with other, relevant deltaic regions around the world. This report provides input for research into common deltaic problems and challenges, identifies strategic research for The Water Institute of the Gulf, and suggests ways that the organization can utilize knowledge gained from the lower Mississippi River and delta system in developing a research program to support water management decisions in other large river/delta complexes.
