Water - and its governance - is becoming a global concern partly
because it is turning into a goods in short supply, with
devastating effects on literally billions of people, but also
because it is the "carrier" ofglobal warming; whether through
irregular weather patterns or through flooding, water is how global
warming will be 'felt'. The lion's share of the globally available
fresh water resources is to be found in transboundary systems. In
spite of its significance, the generated knowledge on how to deal
with transboundary waters is weak and leaves policy makers with
seemingly unavoidable, trade-off dilemmas and prioritizations,
often with detrimental effects. In order to disentangle this
predicament this volume works with one case: the Lower Mekong Basin
and covers state-of-the-art academic and practitioners' knowledge
and hence appeals to a wide audience. The topic this volume
addresses is situated in the nexus ofan IR- (International
Relations) approach focussing on transboundary politics and its
inclination to remain within the sphere of state sovereignty and
national interest on the one hand, and Development studies, with
its imperatives on participation, planning, and intervention, on
the other.The dilemma, we argue, of better understanding
transboundary water management lies in how to understand how these
two rationalities can be simultaneously nurtured.
Environmental argument is 'about' far more than meets the eye. How people (mis)under-stand each other during environmental debates is affected by conflicts between values and ways of life which may not be directly connected with the environment at all. This book offers sociological evidence from three contrasting societies - Ireland, Germany and China - to explore how diversity of cultural context affects deliberation about the physical world. What can we discover by examining environmental debates through the lens of interculturality? When people disagree about flood management, building motorways or extracting gas, what difference does it make if they have diverse experiences of neighbourly relations, how to use time or how to imagine a good life? What is going on at intersections between cultures to influence the trajectories of environmental debates? The book disinters taken-for-granted practices, feelings and social relationships which affect environmental arguments, in scientific and artistic debate as well as in politics and policy-making. Importantly, the book makes visible the effects of cultural difference on people's approaches to arguing itself. If public arguing is shaped by specific habits of feeling or imagination, how does that impact on theories of democracy? Do we need new kinds of arguing to cope with environmental crises? What elements of arguing are decisive in the ways people come to see environmental decisions as wise choices?
In any ecosystem, plant and microbe interaction is inevitable. They not only co-exist but also support each other's survival and also provide for sustenance in stressful environment. Agro-ecosystems of many regions around the globe are affected by multi-stress. Major limiting factors affecting the agricultural productivity worldwide are environmental stresses. Apart from decreasing yield they introduce devastating impact on plant growth as well. Plants battle with various kind of stresses with the help of symbiotic association with the microbes in the rhizosphere. Naturally existing plant-microbe interaction facilitates survival of plants under these stressful conditions. Rhizosphere consists of many groups of microbes, plant growth-promoting bacteria (PGPB) is one such group of microbes which assist plants in coping with multiple stresses and in plant growth as well. These microbes help in stress physiology of the plants and can be extremely useful in solving agricultural as well food security problems. The proposed book is split into two parts, with an aim to provide comprehensive description and highlight a holistic approach. It elucidates various mechanisms in rhizosphere of nutrient management, stress tolerance and enhanced crop productivity. The book discusses rhizospheric flora and its importance in enhancement of plant growth, nutrient content, yield of various crops and vegetables as well as soil fertility and health. Both volumes of the book addresses fundamentals, applications as well as research trends and new prospects of agricultural sustainability. Volume 2: Nutrient Management and Crop Improvement, contains chapters which cover a broad overview of plant growth promoting activities of microbes. This proposed book also highlights the contribution of nitrogen, phosphorus, potassium, iron and zinc-solubilizing microbes from rhizospheric soil to develop efficient indigenous microbial consortia to enhance the food and nutritional security. With the given content and layout the proposed book will be an all-inclusive collection of information, which will be useful for students, academicians, researchers working in the field of rhizospheric mechanisms, agricultural microbiology, soil microbiology, biotechnology, agronomy and sustainable agriculture and also for policy makers in the area of food security and sustainable agriculture. It will be of special interest to both academics and professionals working in the fields of microbiology, soil microbiology, biotechnology and agronomy, as well as the plant protection sciences. Timely, this edited and research book provides an essential and comprehensive source of material from basic to advance findings on microbes and their role in agricultural and soil sustainability.
The book provides basic knowledge in mycorrhizal ecology, knitted with novel conceptual frameworks and contemporary perspectives, especially in the context of global change. In a fast changing world wherein anthropogenic climate change, biological invasions, deforestation, desertification, and frequent droughts have become routine hard realities, the contents of this book urge readers to rethink basic notions of setting and accomplishing objectives in mycorrhizal research to make sense vis-a-vis contemporary challenges. In this book, a global perspective of mycorrhizal diversity and distribution is provided, followed by some insights into the impact of various global change elements such as climate change, plant invasion, and extreme environmental conditions on mycorrhizas and the role of these mutualists in turn to help their host plants to withstand such novel selection pressures. Special attention here is given to the interesting, but largely neglected, topics such as the role of mycorrhizas in ecological restoration of degraded environments and mycorrhizal status of aquatic plants. The basic idea is to unify various topical areas in mycorrhizal science in an integrated framework. This book can be used by the undergraduate and graduate level students studying mycorrhizal symbioses in the context of current ecological applications. The materials in this book will benefit biological scientists actively involved in research on mycorrhizal ecology and global environmental change. Besides, the contents of the book could be of special interest to restoration ecologists and biodiversity managers. "
Playing a critical role in both influencing climate change and mitigating its impacts, the world's diverse wetlands have become one of the world's most threatened ecosystems as unsustainable land-use practices coupled with irrational use of water have already resulted in large-scale wetlands loss and degradation. To develop sound management and conservation schemes to assure wetlands sustainability in the long term requires long-term understanding of wetlands ecology. Yet until now, long-term interdisciplinary research into these systems has been limited to only a few systems from tropical or temperate climates (such as the Florida Everglades, and Czech biosphere reserve). This new book adds to the existing wetlands literature, providing a unique reference in basic and applied Mediterranean wetland ecology, based on results from long-term interdisciplinary research at the RAMSAR and UNESCO Biosphere site, of Las Tablas de Daimiel, Spain. Dating back to the early 1990s the research highlights changes in the biotic and abiotic environment in response to cumulative anthropogenic stressors, and provide guidance on applying this understand to sound management and conservation. With particular relevance to researchers dealing with semi-arid wetlands in the Mediterranean and elsewhere, as well as to resource managers, the book discusses the complexity of the interacting abiotic and biotic environment across different spatial and temporal scales and across various levels of biological hierarchy is highlighted, and reveals how management based on poor knowledge causes more damage than repair. The book will be of interest to researchers interested in freshwater ecology, hydrobotany, hydrology, geology, biogeochemistry, landscape ecology and environmental management.
This volume is for environmental researchers and government policy
makers who are required to monitor environmental quality for their
environmental investigators and remediation plans. It uses concepts
and applications to aid in the exchange of scientific information
across all the environmental science disciplines ranging from

soil-water-plants-chemicals, the book synthesizes the latest
findings in this rapidly-developing, multi-disciplinary field.
Cutting-edge environmental analytical methods are also presented,
making this a must-have for professionals tasked with monitoring
environmental quality. These concepts and applications help in
decision making and problem solving in a single resource.
Sustainable agriculture is a key concept for scientists,
researchers, and agricultural engineers alike.
"Use of Microbes for the Alleviation of Soil Stresses, Volume 1" describes the most important details and advances related to the alleviation of soil stresses by soil microbes. Comprised of seven chapters, the book reviews the mechanisms by which plant growth promoting rhizobacteria (PGPR) alleviate plant growth under stress; the role of mycorrhizal fungi on the alleviation of drought stress in host plants; how PGPR may alleviate salinity stress on the growth of host plants; and the role of PGPR on the growth of the host plant under the stress of sub optimal root zone temperature. Written by experts in their respective fields, "Use of Microbes for the Alleviation of Soil Stresses, Volume 1 "is a comprehensive and valuable resource for researchers and students interested in the field of microbiology and soil stresses.
This volume presents a state-of-the-art assessment of the Earth's climate system in Siberia and relationships between climate, ecosystems and people in that region. Changes in climatic variables and land cover in Siberia are among the earliest indicators of the Earth's response to climate warming. The volume is a compilation of results from studies on climate, land-cover and land-use changes and their interactions with biogeochemical and water cycles, atmospheric aerosol, and human and wildlife populations in Siberia. Regional changes in Siberia are predicted to affect climate and people on a global scale. NASA, the Russian Academy of Sciences, and several European institutions have supported these studies. The primary supporter of the projects that produced the results compiled in this volume is the NASA Land-Cover/Land-Use Change Program, hence most studies use remote sensing in their research. The chapters in this volume were written by an international team of scientists from the USA, Europe and Russia under the auspices of the Northern Eurasia Earth Science Partnership Initiative (NEESPI). This book will be of interest to those involved in studying recent and ongoing changes in Siberia, be they senior scientists, early career scientists or students.
Fungal pathogens pose an on-going and serious threat for poikilotherms and homeotherms, and can cause a broad spectrum of diseases ranging from innocuous to life-threatening. In addition, long-term exposure to some mycotoxigenic moulds can lead to mycotoxicoses in human and animals. Given the expanding population of immune compromised hosts, the list of fungal opportunists grows longer every year. Moreover, antifungal resistance, drug-related toxicity and our limited arsenal of antifungals have exacerbated the situation. To address these problems, strategies such as the identification of novel targets, use of the structure-activity relationship in rational drug design, development of new formulations, modification of existing antifungals to combat resistance, and bioavailability enhancement are called for. For the reader's convenience, this book has been divided into three sections. The first six chapters of Section I provide a timely review of mycoses, from endemic to cosmopolitan and from generalized to specific, while both chapters of Section II focus on risks associated with mycotoxins. In closing, the two chapters of Section III describe potential antifungal leads and drug candidates based on phytochemicals and coumarin scaffold.
Untouched since 1953, the Korean DMZ (Demilitarized Zone) has transformed itself into one of the few ecologically pristine zones and a vital habitat for endangered species. Often cited as a potential "peace park", it could one day be a common ground for reconciliation and harmony. A wealth of data and information has been produced over time, documenting significant aspects of the DMZ and its implications for human and ecological security, both in Korea and worldwide. However, there is no single book in English that brings together the findings on the mechanism of evolution, the ecology and biodiversity of the DMZ. "The DMZ of Korea", by Kwi-Gon Kim, is the first step in this direction. It seeks to link scientific information and policy making for the future DMZ ecosystem management, taking into account the fact that the area has become, over the years, a natural treasure as a habitat for rare birds and other wildlife and a fertile environment for a thriving plant community. It also provides a framework for ensuring the long-term sustainability of the DMZ. The book holistically describes the current environmental status of the DMZ, and identifies bioregions, resources, habitats, and species. By outlining the current scientific data and information needed to classify the different wetland types, assess the biological integrity, understand the threat factors, and to suggest conservation and management strategies, the book provides a "one stop shop" scientific and policy source of information, which will undoubtedly be of great interest to students, researchers, practitioners, and policy decision-makers, in the areas of planning, natural resource management, public management, ecology, landscape architecture, geography, and the life sciences. Prof.Dr.Kwi-Gon Kim obtained his Ph.D. at UCL, University of London, UK. He is a professor emeritus at Seoul National University and the Co- President of the Korea DMZ Council in Seoul, Korea.
The " Radioactivity in the Environment Series" addresses the key
aspects of this socially important and complex interdisciplinary
subject. Presented objectively and with the ultimate authority
gained from the many contributions by the world's leading experts,
the negative and positive consequences of having a radioactive
world around us is documented and given perspective. In a world in
which nuclear science is not only less popular than in the past,
but also less extensively taught in universities and colleges, this
book series will fill a significant educational gap.
In 1837 a young Charles Darwin took his notebook, wrote "I think" and then sketched a rudimentary, stick-like tree. Each branch of Darwin's tree of life told a story of survival and adaptation - adaptation of animals and plants not just to the environment but also to life with other living things. However, more than 150 years since Darwin published his singular idea of natural selection, the science of ecology has yet to account for how contrasting evolutionary outcomes affect the ability of organisms to coexist in communities and to regulate ecosystem functioning. In this book Philip Grime and Simon Pierce explain how evidence from across the world is revealing that, beneath the wealth of apparently limitless and bewildering variation in detailed structure and functioning, the essential biology of all organisms is subject to the same set of basic interacting constraints on life-history and physiology. The inescapable resulting predicament during the evolution of every species is that, according to habitat, each must adopt a predictable compromise with regard to how they use the resources at their disposal in order to survive. The compromise involves the investment of resources in either the effort to acquire more resources, the tolerance of factors that reduce metabolic performance, or reproduction. This three-way trade-off is the irreducible core of the "universal adaptive strategy theory" which Grime and Pierce use to investigate how two environmental filters selecting, respectively, for convergence and divergence in organism function determine the identity of organisms in communities, and ultimately how different evolutionary strategies affect the functioning of ecosystems. This book reflects an historic phase in which evolutionary processes are finally moving centre stage in the effort to unify ecological theory, and animal, plant and microbial ecology have begun to find a common theoretical framework.

This book provides a broad overview of how the promotion of ocean and coastal literacy is being planned, applied and evaluated in Brazil, a country of continental dimensions with a great diversity of cultural, educational and social realities. It discusses a range of target groups, from children to adults; formal and informal strategies; and various promoting players, such as groups/institutions. Researchers representing Brazilian academic institutions and NGOs share their environmental education (EE) experiences in Brazil and describe the main concerns regarding the marine and coastal environments as well as how they are addressing these concerns in their EE projects. This book is of interest to anyone who is looking for ways of designing and implementing EE activities with a robust theoretical background in different socio-cultural scenarios.
Technological improvements have greatly increased the ability of
marine scientists to collect and analyze data over large spatial
scales, and the resultant insights attainable from interpreting
those data vastly increase understanding of poplation dynamics,
evolution and biogeography. "Marine Metapopulations " provides a
synthesis of existing information and understanding, and frames the
most important future directions and issues.
The Asko meetings were an annual forum where leading economists and ecologists came together to discuss the myriad issues and challenges surrounding sustainable development. Organized by the Beijer Institute of Ecological Economics and held on the Island of Asko in the Stockholm Archipelago, Sweden, the meetings facilitated a dialogue in which various players with differing perspectives could arrive at common conclusions and solutions that benefit us all.
Central Asia is vulnerable to water scarcity because it is located in semiarid and arid vegetation zones and large parts of its economy depend on water for irrigation and energy. Climate-change scenarios predict temperature increases and a rising number of extreme weather events, which will exacerbate water shortages in the future. In addition, the population of Central Asia is growing more rapidly than the rate of food production which is resulting in food insecurity in many parts of the region too. This volume reports the deliberations of politicians, scientists and representatives of water management organizations from throughout Central Asia. Their contributions not only highlight areas of concern, but also propose numerous ideas for improving the long-term water- and food security in the region.
Fire Ecology of Tropical Ecosystems gives an extensive explanation of historic and current fire situations in the tropics, describing the fire ecology of tropical ecosystems from around the globe. Eighteen groups of leading researchers explain the many different aspects and roles of fire in tropical ecosystems. Regional chapters address a set of common subjects including the causes of fire, typical fire behavior, and elements of the fire regime. In addition, they study the impacts of human land use, landscape fragmentation and climate change on the fire environment and the challenges of fire management in these ecosystems. The common set of topics provides consistency among the chapters and facilitates comprehensive understanding of fire s place in tropical ecology. This cohesive book covers unique aspects of fire in each ecosystem and includes a discussion of common elements to enable comparisons and syntheses of fire effects in disparate tropical ecosystems. Current scientific literature is too fragmented: it hampers the understanding of tropical fire ecology and degrades all global studies of land cover change and global carbon emissions. Fire Ecology of Tropical Ecosystems fills a large void in our current understanding of how fire affects terrestrial biota. The book opens with a general explanation of fire in the tropics, giving the examples of Oazaca, Mexico in 1998 and Roraima, Brazil in 1997-1998. It follows with the concepts and principles of wildland fire, including heat transfer, fire behavior, fuels, weather and climate. Chapters 3-19 cover the implications of fire in Asia, Africa, Australia, Central and South America, Pacifica and Pantropical, addressing the causes, fire behavior, severity, fire and land use, fire and landscapes (fragmentation and connectivity), fire, climate and climate change, fire regimes (why frequency matters), issues for fire management and regional issues of specific importance or interest. An overview at the end of the book considers the global fire regime conditions, threats, and opportunities for fire management in the tropics."
The key novelty of this book is first of all in the successful attempt to conduct jointly modeling of environment in terms of physical environment related parameters and measuring similar parameters by means of multispectral remote sensing, primarily by means of passive microwave remote sensing technology. Another new step is in the development and utilization of a multilevel approach which includes remote sensing of the land and water parameters like soil moisture, depth to water table, biomass of vegetation, temperature and salinity of water, in situ measurements of similar parameters and incorporation of GIS and data sets into the models of typical environments. The part of book, which contains remote sensing is focused on multipurpose observations from aircraft obtained in many soil-climatic zones in different countries and is reach of the examples of practical application. Applied mathematicians, geophysics, hydrologists, socio-economists, statesmans and other researchers of environmental changes will find a wealth of information and ideas in this book.
This book presents selected contributions of the 34th International School of Hydraulics that was held in May 2015 in Zelechow, Poland. It gives an overview about the state of the art in environmental hydraulics. A special emphasis is put upon physical, biochemical and ecological processes that act at interfaces in natural surface water bodies but also other important hydraulic problems are considered. The achievements of well-known researchers from all over the world as well as the results obtained by young researchers, among others within a Marie Curie funded Initial Training Network, led by the University of Padua (HYTECH - HYdrodynamic Transport at Ecologically Critical Heterogeneous Interfaces) are gathered in this volume. |
