This title discusses various effects of heavy metal exposure to legumes as well as the bioremediation potential of rhizosphere microbes. Availability of heavy metals, their uptake and the effects of metals on various signaling pathways within legumes are presented. Furthermore, the effects of heavy metals to nitrogen fixing microorganisms and how microsymbionts can overcome metal stress is presented in detail. The role of nitrogen fixers in decontamination of heavy metal toxicity, mycoremediation of metal contaminated soils, microbially mediated transformation of heavy metals and action of plant growth promoting rhizobacteria and nitrogen fixers together in detoxifying heavy metals are broadly explained. This volume is a useful tool for scientists, policy makers and progressive legume growers intending to develop safe and healthy legumes for future generations.
In dealing with the IUCN, one must bear in mind that there never has been, and undoubtedly never will be, any other organization even remotely resembling it. Its peculiarities, subtleties and complexities are sometimes mind-boggling (Nicholson 1990 in Holdgate 1999: ix). Green Web-II investigates IUCN's role in global biodiversity conservation policy as well as in national program development in India, Pakistan, Nepal and Bangladesh. It explores how nature protection priorities and approaches are promoted or addressed by IUCN, an international organization, and how environment conservation policies are created and maintained in states with different capacities of South Asia. It also evaluates IUCN's competency in bio-diversity, climate change, nature conservation and environmental policy formulation at global, regional and country level. This study is the first detailed scholarly study on the IUCN as an organization as well as on its efforts in biodiversity conservation. This book adds to our knowledge, firstly by contributing to a small but growing body of work on the sociology of international organizations. IOs, especially International Governmental Organizations (IGOs), have long been the subject of mostly political science. Secondly, it applies a fuller sociological imagination to the study of IOs by critically exploring one of the largest and most active nature conservation organizations in the world. Thirdly, it also explores how the IUCN actually goes about building protectoral programs with individual member nations. Additionally, the book explores the recent development of the green economy (GE) concepts into IUCN's program planning today. The green economy initiative applies a people-first approach. Although the concept is relatively new, this research explores the theoretical development of a green economy and illustrates how this theory is applied in IUCN's program planning to program implementation. Technical topics discussed in the book include: Motivation of Environment Conservation - How personal efforts make difference Role of International Environment Conservation Organizations Political Economy of Organizations, Network theory, Institutional theory, Stakeholder theory, Governance theory Governance performances and Competitiveness Popularity indices Knowledge creation and diffusion Conservation commons
Forest inventories throughout the world have evolved gradually over time. The content as well as the concepts and de?nitions employed are constantly adapted to the users' needs. Advanced inventory systems have been established in many countries within Europe, as well as outside Europe, as a result of development work spanning several decades, in some cases more than 100 years. With continuously increasing international agreements and commitments, the need for information has also grown drastically, and reporting requests have become more frequent and the content of the reports wider. Some of the agreements made at the international level have direct impacts on national economies and international decisions, e. g. , the Kyoto Protocol. Thus it is of utmost importance that the forest information supplied is collected and analysed using sound scienti?c principles and that the information from different countries is comparable. European National Forest Inventory (NFI) teams gathered in Vienna in 2003 to discuss the new challenges and the measures needed to get data users to take full advantage of existing NFIs. As a result, the European National Forest Inventory Network (ENFIN), a network of NFIs, was established. The ENFIN members decided to apply for funding for meetings and collaborative activities. COST- European Cooperation in Science and Technology - provided the necessary ?n- cial means for the realization of the program.
This book presents a comprehensive typology and a comprehensible description of spatiotemporal models used in population dynamics. The main types included are: reaction-diffusion systems, patch models, matapopulation approaches, host parasitoid models, cellular automata (interacting particle systems), tessellations and distance models. The models are introduced through examples and with informative verbal explanations to help understanding. Some of the cellular automation examples are models not yet published elsewhere. Possible extensions of certain model types are suggested.
Debate about how best to ensure the preservation of agricultural biodiversity is caught in a counter-productive polemic between proponents and critics of market-based instruments and agricultural modernisation. This book argues that neither position does justice to the range of strategies that farmers use to manage agrobiodiversity and other livelihood assets as they adapt to changing social, economic, and environmental circumstances. Chapters explore relationships between the exploitation and conservation of agricultural biodiversity and the livelihoods of agricultural communities, and evaluate the capacity of national and multilateral institutions and policy settings to support the protection and capture by communities of agrobiodiversity values. The place of ecosystem services in valuing biodiversity in the marketplace is emphasized. A number of authors assess the potential for market-based instruments and initiatives to encourage the protection of biodiversity, while others compare agrobiodiversity/community relationships, and the effectiveness of instruments designed to enhance these, across international boundaries. The book takes a comparative approach, drawing on empirical case studies from across the developed and developing worlds. In doing so, the book does not simply point to similarities and differences in the experience of rural communities. It also shows how global trade and multilateral institutions bring these otherwise disparate communities together in networks that exploit and/or preserve agrobiodiversity and other resources.
Growing concerns about the impacts of climate change and dependence on fossil fuels have intensified interest in bioenergy from sugar cane and other crops, highlighting important links between energy, environment and development goals. Sub-Saharan Africa is characterized by severe poverty; the possibility to exploit a renewable energy resource offers valuable avenues for sustainable development and could support a more dynamic and competitive economy. This book describes how the bioenergy expansion will improve rural livelihoods, reduce costly energy imports, reduce GHG emissions, and offer new development paths. Drawing on international experience, it is shown that harnessing this potential will require significant increases in investment, technology transfer, and international cooperation. Because of its high efficiency, the authors argue that sugar cane should be viewed as a global resource for sustainable development and should command much greater focus and concerted policy action. Through an analysis of the agronomy, land suitability and industrial processing of sugar cane and its co-products, along with an assessment of the energy, economic and environmental implications, this volume demonstrates that sugar cane offers a competitive and environmentally beneficial resource for Africa's economic development and energy security. With fourty-four authors representing thirty organisations in sixteen countries, the book offers a truly international and interdisciplinary perspective by combining technical and economic principles with social, political and environmental assessment and policy analysis.
The field of insect nutritional ecology has been defined by how insects deal with nutritional and non-nutritional compounds, and how these compounds influence their biology in evolutionary time. In contrast, Insect Bioecology and Nutrition for Integrated Pest Management presents these entomological concepts within the framework of integrated pest management (IPM). It specifically addresses bioecology and insect nutrition in modern agriculture. Written for graduate students and professionals in entomology, this book covers neotropical information in three sections:
Much of the research on which these chapters were written was done in Brazil and based on its neotropical fauna. The complexity and diversity of the neotropics provides enough data that readers from all zoogeographical regions can readily translate the information in this book to their specific conditions. The book s value as an entry point for further research is enhanced by the inclusion of approximately 4,000 references.
This proceedings volume examines leadership from the perspectives of business, economics, social sciences, cross-cultural management, and education as a means to establish a future of sustainable development. Featuring contributions from the 2017 Prague Institute for Qualification Enhancement (PRIZK) and International Research Centre (IRC) "Scientific Cooperation" International Conference held in the Czech Republic, this volume focuses particularly on business models and higher education schemes from BRICS nations and examines topics such as social and educational practices, academic policies and business development. Leadership is becoming a key element for the future sustainable development of business and education in the quickly globalizing world. In this regard, a special emphasis should be made on the formation of high-quality human resources-the leading experts in their field who will create innovations and introduce breakthrough technologies. The development of a creative economy and knowledge economy requires highly-educated human capital, thus education becomes a key element of this process. Education must keep pace with time, be competitive, and stay in touch with the process of technology. The enclosed papers identify the key steps for sustainable growth and development in business and education. Featuring contributions on theory and practice, this book is appropriate for academics, researchers, policy-makers and practitioners in the areas of business, leadership management, entrepreneurship, innovation and education.
Regions with Mediterranean-type climates include parts of
California, South America, Australia, and of course, Europe. The
effect of global climate change on these heavily populated areas
will have major social and political ramifications.
From its inception, the U.S. Department of the Interior has been charged with a conflicting mission. One set of statutes demands that the department must develop America's lands, that it get our trees, water, oil, and minerals out into the marketplace. Yet an opposing set of laws orders us to conserve these same resources, to preserve them for the long term and to consider the noncommodity values of our public landscape. That dichotomy, between rapid exploitation and long-term protection, demands what I see as the most significant policy departure of my tenure in office: the use of science-interdisciplinary science-as the primary basis for land management decisions. For more than a century, that has not been the case. Instead, we have managed this dichotomy by compartmentalizing the American landscape. Congress and my predecessors handled resource conflicts by drawing enclosures: "We'll create a national park here," they said, "and we'll put a wildlife refuge over there." Simple enough, as far as protection goes. And outside those protected areas, the message was equally simplistic: "Y'all come and get it. Have at it." The nature and the pace of the resource extraction was not at issue; if you could find it, it was yours.
Because marine governance in most countries is sectoral, maritime policies are frequently fragmented, reactive, and even contradictory, meaning that marine resources are underutilized and poorly protected. To avoid these problems, the concept of integrated national maritime policy (INMP) has been developed. This book examines this concept, analysing its current application in four countries Australia, Canada, UK and USA whilst discussing at length how it might be applied to Saudi Arabia. Based on extensive fieldwork carried out in Saudi Arabia including interviews with officials in government departments with maritime responsibilities, and a survey administered to 230 stakeholders the book offers a unique insight into INMP in the Kingdom. The book provides a practical template for developing the political will and civil constituency in Saudi Arabia necessary for the introduction of INMP. In setting out in detail its benefits, this book could help build the momentum in Saudi Arabia required to implement the concept as well as attract other countries to do the same. A significant contribution to the growing literature on ocean governance, this book will be of great importance to policy makers and scholars of Middle Eastern studies, marine governance and comparative politics.
Conservation genetics focuses on understanding the role and
requirement of genetic variation for population persistence.
However, considerable debate now surrounds the role of genetic
factors (as opposed to non-genetic factors such as habitat
destruction etc.) in population extinction, and a comprehensive
synthesis is now timely. Can extinction be explained by habitat
destruction alone or is lack of genetic variation a part of the
explanation? The book thoroughly reviews the arguments for a role
of genetics in the present biodiversity crisis. It describes the
methods used to study genetic variation in endangered species and
examines the influence of genetic variation in the extinction of
species.
Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy, and significant areas of accomplished or needed endeavor in the total field of xenobiotics in any segment of the environment, as well as toxicological implications.
This book describes the outstanding features of the ecology and bio geography of the Indian region, comprising former British India, Nepal, Bhutan, Ceylon and Burma. It summarizes the results of nearly four decades' studies and field explorations and discussions with students on the distribution of plants and animals, practically throughout this vast area and on the underlying factors. A number of specialists in geology, meteorology, botany, zoology, ecology and anthropology have also actively collaborated with me and have contributed valuable chapters in their respective fields. India has an exceptionally rich and highly diversified flora and fauna, exhibiting complex composition, character and affinities. Although the fauna of the Indian region as a whole is less completely known than its flora, we are nevertheless fairly well acquainted with at least the salient features of its faunal characters to enable us to present a meaningful discussion on some of the outstanding peculiarities of the biogeography of India. A general synthesis of the available, though much scattered, information should prove useful to future students of biogeography throughout the world."
The United States Forest Service, perhaps more than any other federal agency, has made great strides during the past two decades revolution izing its public involvement efforts and reshaping its profile through the hiring of professionals in many disciplinary areas long absent in the agency. In fact, to a large extent, the agency has been doing precisely what everyone has been clamoring for it to do: involving the public more in its decisions; hiring more wildlife biologists, recreation specialists, sociologists, planners, and individuals with "people skills"; and, fur thermore, taking a more comprehensive and long-term view in planning the future of the national forests. The result has been significant-in some ways, monumental-changes in the agency and its land manage ment practices. There are provisions for public input in almost all as pects of national forest management today. The profeSSional disciplines represented throughout the agency's ranks are markedly more diverse than they have ever been. Moreover, no stone is left untumed in the agency's current forest-planning effort, undoubtedly the most compre hensive, interdisciplinary planning effort ever undertaken by a resource agency in the United States. Regardless of the dramatic change that has occurred in the U. S. Forest Service since the early 1970s, the agency is still plagued by con flicts arising from dissatisfaction th how it is doing business."
During the last 10 years, there has been a revolution' in ecosystem modelling. The generality and predictive power of our models have increased in a way that was inconceivable 10 years ago. This book describes a new generation of practically useful models that predict as well as one can measure - if one measures well. And yet, they are driven by readily available driving variables and have a general structure that applies to most types of pollutants in aquatic systems. The major reason for this development is, in fact, the Chernobyl accident. Large quantities of radiocesium were released in April/May 1986 as a pulse. To follow the pulse of radiocesium through ecosystem pathways has meant that important fluxes and mechanisms, i.e., ecosystem structures, have been revealed. It is important to stress that many of these new structures and equations are valid not just for radiocesium, but for most types of contaminants, e.g. for metals, nutrients and organics. This means that the models, methods (of building and testing models) and equations described in this book for lakes and coastal areas should be of great interest also to other ecosystem modellers. This book will be of considerable interest to: students in radioecology, geosciences and biology; environmental engineers; consultants; administrators and scientists interested in the spread, biouptake and ecosystem effects of chemical pollutants in aquatic ecosystems.
The first edition of the widely praised Marine Protected Areas for Whales, Dolphins and Porpoises, published in 2005, led to numerous new marine protected area proposals and a number of notable conservation successes around the world. In this completely revised and expanded second edition, new developments in the Mediterranean, Caribbean and Pacific are described, as well as future directions for High Seas protection. New sections show how to design and manage Marine Protected Areas (MPA's) in an ever noisier ocean subject to climate change, increased shipping and hydrocarbon exploration. The process of protected area creation for cetaceans has been accelerated and more than 200 exciting new places are detailed in this edition. This book provides a route map for MPA managers, as well as countries, to meet the ambitious targets for highly protected MPA networks by 2012 and 2020. Marine Protected Areas for Whales, Dolphins and Porpoises is a key conservation tool and a springboard for worldwide change in human attitudes toward the world ocean where all life originated and where the majority of life on Earth still lives.
Heavy metal pollution is a serious threat to living organisms. Industrial development has aggravated multifaceted problems in the environment requiring a comprehensive solution. Appraisal of Metal(loids) in the Ecosystem addresses this need and provides a basic introduction of different heavy metals. Presented in a consistent and comprehensive manner, each chapter highlights the background level, occurrence, speciation, bioavailability, uptake detoxification mechanisms, and management of each metal in polluted soils. It provides the latest up-to-date information about different aspects of As, Hg, Si, Cu, Co, Ni, Mn, Cd, Cr, etc. in single source. This book provides scientists and researchers with the most current source of information on the topic. Written by a global and diverse group of experts, Appraisal of Metal(loids) in the Ecosystem also covers the many field applications associated with phytoremediation and extraction and provides guidance on decision making when selecting advanced techniques.
Biological homogenization is the dominant process shaping the future global biosphere. As global transportation becomes faster and more frequent, it is inevitable that biotic intermixing will increase. Unique local biotas will become extinct only to be replaced by already widespread biotas that can tolerate human activities. This process is affecting all aspects of our world: language, economies, and ecosystems alike. The ultimate outcome is the loss of uniqueness and the growth of uniformity. In this way, fast food restaurants exist in Moscow and Java Sparrows breed on Hawaii. Biological homogenization qualifies as a global environmental catastrophe. The Earth has never witnessed such a broad and complete reorganization of species distributions.
The African lakes are an extremely important ecosystem and the subject of much study relating to species introductions and loss of biodiversity. This book provides a thorough review of the whole subject and will be of great interest to fish biologists, fisheries workers, ecologists, environmental scientists and conservationists.
The marine environment is one of our most precious yet fragile natural resources. It provides a wide range of essential goods and services, including food, regulation of climate and nutrient cycling, as well as a setting for transport, recreation and tourism. This environment is however extremely complex and very sensitive to development pressures and other forms of human influence. Planning and management of the sea are similarly complicated, reflecting intricate legal, institutional and ownerships patterns. This creates a situation where marine ecosystems are vulnerable to over-exploitation or neglect. The Ecosystem Approach to Marine Planning and Management describes how growing concern about the state of our seas is resulting in the development of new approaches to marine planning and management. For example, the United Nations Environment Programme has called for the widespread introduction of Marine Spatial Planning (MSP), and the European Union has recently been consulting on a new European Maritime Policy designed to stimulate economic growth but at the same time protect the resource base. Within the United Kingdom, the 2010 Marine Act draws upon the experience of town and country planning and brings into being a new system of Marine Spatial Planning. The authors show that a common feature of all these developments is an appreciation that more integrated forms of planning and management are required for our seas and that new arrangements must draw together understanding from natural science, social science and many other perspectives. Adopting such a trans-disciplinary and holistic (or 'ecosystems') approach, the book distils the expertise of these different disciplines and seeks to promote a broader understanding of the origins and practicalities of new approaches to marine planning and management. |
