The Biodiversity Observation Network in the Asia-Pacific Region
by Shin-Ichi Nakano Tetsukazu Yahara Tohru NakashizukaBiological diversity is important for ecosystem function and services, which in turn is essential for human well-being. Under the Convention on Biological Diversity, international efforts have been made to achieve a significant reduction in the current rate of biodiversity loss. The loss continues, however. The Asia-Pacific region includes both developing countries with high biodiversity and developed countries with sophisticated data collection and analyses, but only limited information about the status quo of biodiversity in this region has been available. Many Asia-Pacific countries have rapidly grown their economies and social infrastructures, causing a loss of biodiversity and requiring an urgent mandate to achieve a balance between development and conservation in the region. In December 2009, scientists successfully organized the Asia-Pacific Biodiversity Observation Network in the region, to establish a network for research and monitoring of ecosystems and biodiversity and to build a cooperative framework. The present volume is the first collection of information on biodiversity in the Asia-Pacific and represents a quantum step forward in science that optimizes the synergy between development and biodiversity conservation.
Biodiversity of Armenia
by George FayvushArmenia is a small landlocked mountainous country located in the Southern Caucasus. It is a typical mountainous country, having its lowest point of 375m above sea level and culminating at 4095m with an average altitude of 1850m, where the landscapes and ecosystems form a complex multi-functional system. In general, the ecosystems of Armenia are characterized by a number of peculiarities, which all together contribute to formation of rich and unique biodiversity. On the small territory of Armenia (less than 30 thousand km2) there are about 3800 species of vascular plants (about a half of the whole Caucasian flora), 428 species of soil and water algae, 399 species of mosses, 4207 species of fungi, 464 species of lichens, 549 species of vertebrates and about 17200 species of invertebrates. The biodiversity of Armenia is notable for high endemism: about 500 species of fauna (about 3% of the fauna) and 147 species of flora (3.8% of total flora) are considered endemics. Such a high level of endemism is typical only for some of the large islands. Due to the huge variety of climates (from dry subtropics to cold alpine) and soil conditions all the main Caucasian ecosystems (besides humid subtropics) are represented in Armenia – deserts and semi-deserts, steppes, meadow-steppes, forests and open woodlands, sub-alpine and alpine vegetation as well as intrazonal ecosystems. Therefore Armenia is a biodiversity hotspot both within the Caucasian ecoregion and around the globe. This book compiles, summarizes and analyzes data on flora, fauna and mycobiota of Armenia, with a special focus on the impact of forecasted climate change on biodiversity and ecosystems of the region.
Biodiversity of Lianas (Sustainable Development and Biodiversity #5)

The interest in lianas has increased over the last two decades. The ultimate goal of this book is to provide an insight into the patterns of liana diversity, distribution, the role of lianas in structuring forest community, and functional ecology (carbon uptake, ecosystem services, dynamics and invasion), biotechnological tool for conservation of lianas and finally summarizes the significance and the need for conservation of lianas in the changing global environmental scenario.
Biodiversity of the Gulf of Guinea Oceanic Islands: Science and Conservation
by Luis M. P. Ceríaco Ricardo F. de Lima Martim Melo Rayna C. BellThis open access book presents a comprehensive synthesis of the biodiversity of the oceanic islands of the Gulf of Guinea, a biodiversity hotspot off the west coast of Central Africa. Written by experts, the book compiles data from a plethora of sources – archives, museums, bibliography, official reports and previously unpublished data – to provide readers with the most updated information about the biological richness of these islands and the conservation issues they face. The Gulf of Guinea Oceanic Islands (Príncipe, São Tomé and Annobón and surrounding islets) present extraordinary levels of endemism across different animal, fungi and plant groups. This very high endemism likely results from the long geological history of the islands and their proximity to the diversity-rich continent. Many researchers, students and conservationists from across the globe are interested in documenting biodiversity on the islands, understanding the evolutionary origins of this diversity, and mitigating the impacts of global change on this unique archipelago. This book aims to be a primer for a broad audience seeking baseline biodiversity information and to serve as a roadmap for future research efforts aiming to fill knowledge gaps in understanding and conserving the unparalleled biodiversity of the Gulf of Guinea islands.
Biodiversity of the Himalaya: Jammu and Kashmir State (Topics in Biodiversity and Conservation #18)
by Ghulam Hassan Dar Anzar A. KhurooThe Himalaya, a global biodiversity hotspot, sustains about one-fifth of the humankind. Nestled within the north-western mountain ranges of the Himalaya, the Jammu and Kashmir (J&K) State harbours more than half of the biodiversity found in the Indian Himalaya. The wide expanse of State, spread across the subtropical Jammu, through the temperate Kashmir valley, to the cold arid Ladakh, is typical representative of the extensive elevational and topographical diversity encountered in the entire Himalaya.This book, the most comprehensive and updated synthesis ever made available on biodiversity of the J&K State, is a valuable addition to the biodiversity literature with global and regional relevance. The book, arranged into 7 parts, comprises of 42 chapters contributed by 87 researchers, each of whom is an expert in his/her own field of research. The precious baseline data contained in the book would form the foundation for assessing current status of knowledge about the bioresources, identify the knowledge gaps, and help prioritization of conservation strategies to steer the sustainable use of biodiversity in this Himalayan region. Given the breadth of topics covered under the banner of biodiversity in this book, it can surely serve as a model for documentation of biodiversity in other regions of the world. The book will be of immense value to all those who, directly or indirectly, have to deal with biodiversity, including students, teachers, researchers, naturalists, environmentalists, resource managers, planners, government agencies, NGOs and the general public at large.
Biodiversity Offsets: The European Perspective On No Net Loss Of Biodiversity And Ecosystem Services
by Wolfgang Wende Fabien Quétier Matt Rayment Marianne Darbi Graham TuckerThis book deals with the new concept of biodiversity offsets. The aim of offsetting schemes is to achieve no let loss or even net gain of biodiversity. Offsets obey a mitigation hierarchy and reflect the precautionary and polluter-pays principle in regard to project impacts. Readers gain insights into current debates on biodiversity policies, with top experts outlining theoretical principles and the latest research findings. At the same time the focus is on practical application and case studies. Today there is a lively international discussion among practitioners and scientists on the optimal legal framework, metrics and design of habitat banks to ensure the success of biodiversity offsets and to minimise the risks of failure or misuse. Contributing to the debate, this volume presents the activities and practices of biodiversity offsetting already implemented in Europe in selected EU member states, and the lessons that can be learnt from them. Readers may be surprised at how much experience already exists in these countries. A further aim of the book is to offer grounded insights on the road ahead, and foster a more intensive and fruitful discussion on how offsetting can be extended and improved upon, so that it becomes a key and effective component of Europe’s biodiversity conservation policy framework.
Biodiversity Offsets Between Regulation and Voluntary Commitment: A Typology of Approaches Towards Environmental Compensation and No Net Loss of Biodiversity
by Marianne DarbiWe are witnessing an alarming, global biodiversity crisis with an ongoing loss of species and their habitats. In response, a number of tools and approaches – including some that are contested – are being explored and promoted. Biodiversity offsets are one such approach, and deserve critical examination since the debate surrounding them has often been oversimplified and lacking practical evidence. As such, this study presents a refined typology including seven types of biodiversity offsets and taking into account different contexts, governance arrangements and drivers. It draws on a detailed analysis of theoretical concepts to explain the voluntary implementation of biodiversity offsets using an internet-based (netnographic) research approach. Furthermore it builds on a broad global explorative base of 72 practical examples and presents in-depth case studies for each type. The results reveal a number of global tendencies that allow recommendations to be made for different locations, contexts and stakeholders. They also encourage the expansion of this research field to respond to the pressing needs of policy and practice.
Bioeconomy and Global Inequalities: Socio-Ecological Perspectives on Biomass Sourcing and Production
by Maria Backhouse Rosa Lehmann Kristina Lorenzen Malte Lühmann Janina Puder Fabricio Rodríguez Anne TittorThis open access book focuses on the meanings, agendas, as well as the local and global implications of bioeconomy and bioenergy policies in and across South America, Asia and Europe. It explores how a transition away from a fossil and towards a bio-based economic order alters, reinforces and challenges socio-ecological inequalities. The volume presents a historically informed and empirically rich discussion of bioeconomy developments with a particular focus on bio-based energy. A series of conceptual discussions and case studies with a multidisciplinary background in the social sciences illuminate how the deployment of biomass sources from the agricultural and forestry sectors affect societal changes concerning knowledge production, land and labour relations, political participation and international trade. How can a global perspective on socio-ecological inequalities contribute to a complex and critical understanding of bioeconomy? Who participates in the negotiation of specific bioeconomy policies and who does not? Who determines the agenda? To what extent does the bioeconomy affect existing socio-ecological inequalities in rural areas? What are the implications of the bioeconomy for existing relations of extraction and inequalities across regions? The volume is an invitation to reflect upon these questions and more, at a time when the need for an ecological and socially just transition away from a carbon intensive economy is becoming increasingly pressing.
The bioeconomy and non-timber forest products (Earthscan Studies in Natural Resource Management)
by Carsten Smith-Hall James L. ChamberlainThis book provides the first in-depth investigation of how non-timber forest products are an integral part of local, national, and global bioeconomies. While the plants and fungi that produce non-timber forest products are essential to the sustainability of forest ecosystems, peoples' food and livelihood security and sovereignty, and thus the bioeconomy, are often absent from bioeconomic strategies. Presenting a selection of empirical cases from around the world that engage with the bioeconomy and non-timber forest products, this volume reveals how essential these products are to creating a greener and more sustainable future, how to to better integrate them into efforts to transition to and expand the bioeconomy, and how such efforts can be supported and developed. Chapters analyse how and to what degree non-timber forest products promote sustainable resource use, generate employment, and contribute to food and livelihood security and poverty alleviation. The volume develops approaches and identifies interventions and policies to support the integration of non-timber forest products into bioeconomy strategies, including in national reporting schemes to provide recommendations for future research and practical implementation. This book will be of great interest to students and scholars of forest and natural resource management, bioeconomics, circular economy and ecological economics more widely. It will also be of interest to professionals working in sustainable development and the forestry sector.
The Bioeconomy Approach: Constraints and Opportunities for Sustainable Development (Routledge Studies in Food, Society and the Environment)
by Udaya Sekhar NagothuThis book examines the bioeconomy concept, analysing the opportunities it can generate, the constraints and the potential benefits for society. The main objective of bioeconomy is to promote economic development, by creating jobs and enhancing the sustainable utilization of bio-resources. A primary driver of bioeconomy strategy, therefore, is the need to respond to the growing population's food and economic requirements. While today research and literature related to bioeconomy are limited, this book presents a unique collection of perspectives on the complex dimensions of the bioeconomy debate. Drawing on the experiences from Europe, Asia and Africa, it presents an international overview. The chapters address a wide range of issues, including coastal-land interactions, ecosystem services, food production, rural development, agriculture, forest management and bioenergy. As a whole, the volume outlines what role bioeconomy can play in contributing to the United Nations Sustainable Development Goals (SDGs) without compromising on the ecological sustainability and equitable distribution of benefits. The book concludes by providing recommendations for developing bioeconomy in respective sectors (agriculture, forestry, fisheries, renewable energy) and directions for planning future bioeconomy programmes and strategies. The Bioeconomy Approach will be of great interest to students and scholars of ecological economics, development economics and environmental economics, as well as policy-makers and practitioners involved in sustainable development.
Bioenergy for Sustainable Development and International Competitiveness: The Role of Sugar Cane in Africa
by Francis X. JohnsonGrowing 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 forty-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.

Biofuels: Greenhouse Gas Mitigation and Global Warming
by Ashwani Kumar Shinjiro Ogita Yuan-Yeu YauThis timely book is a compilation of edited articles by distinguished international scientists discussing global warming, its causes as well as present and future solutions. Social and economic growth at global level is measured in terms of GDP, which requires energy inputs generally based on fossil fuel resources. These, however, are major contributors to increasing levels of CO2, causing 15 tonnes of green house gas emissions per capita. Renewable sources of energy offer an alternative to fossil fuels, and would help reduce this to the 2 tonnes of greenhouse gas emissions per capita per annum needed to achieve sustainable growth. As such, the book discusses the next-generation of biofuels and all related aspects, based on the editors’ significant investigations on biofuels over the last 30 years. It also presents the latest research findings from research work carried out by contemporary researchers. Presenting global biofuel perspectives, it examines various issues related to sustainable development of biofuels in the contexts of agriculture, forestry, industry and economic growth. It covers the 1st to 4th generation biofuels, as well as the status of biofuel resources and their potential in carbon neutral economy. Offering a comprehensive, state-of-art overview of current and future biofuels at local and global levels, this book appeals to administrators, policy makers, universities and research institutions.
Biofuels and Sustainability: Holistic Perspectives for Policy-making (Science for Sustainable Societies)
by Hideaki Shiroyama Osamu Saito Kazuhiko Takeuchi Masahiro MatsuuraThis open access book presents a comprehensive analysis of biofuel use strategies from an interdisciplinary perspective using sustainability science. This interdisciplinary perspective (social science-natural science) means that the strategies and policy options proposed will have significant impacts on the economy and society alike. Biofuels are expected to contribute to reducing greenhouse gas emissions, revitalizing economies in agricultural communities and alleviating poverty. However, despite these anticipated benefits, international organizations such as the FAO, OECD and UN have published reports expressing concerns that biofuel promotion may lead to deforestation, water pollution and water shortages. The impacts of biofuel use are extensive, cross-sectoral and complex, and as such, comprehensive analyses are required in order to assess the extent to which biofuels can contribute to sustainable societies. Applying interdisciplinary sustainability science concepts and methodologies, the book helps to enhance the establishment of a sustainable society as well as the development of appropriate responses to a global need for urgent action on current issues related to biofuels.
Biofuels for Transport: Global Potential and Implications for Sustainable Energy and Agriculture
by Worldwatch InstituteThe world is on the verge of an unprecedented increase in the production and use of biofuels for transport. The combination of rising oil prices, issues of security, climate instability and pollution, deepening poverty in rural and agricultural areas, and a host of improved technologies, is propelling governments to enact powerful incentives for the use of these fuels, which is in turn sparking investment. Biofuels for Transport is a unique and comprehensive assessment of the opportunities and risks of the large-scale production of biofuels. The book demystifies complex questions and concerns, such as thefood v. fuel debate. Global in scope, it is further informed by five country studies from Brazil, China, Germany, India and Tanzania. The authors conclude that biofuels will play a significant role in our energy future, but warn that the large-scale use of biofuels carries risks that require focused and immediate policy initiatives. Published in association with BMELV, FNR and GTZ.
Biofuels in Africa
by Donald Mitchell DonaldA new economic opportunity for sub-Saharan Africa is looming large: biofuel production. Rapidly rising energy prices are expected to remain high for an extended period of time because of the increasing demand in prospering and populous countries such as China and India, the depletion of easily accessible supplies of crude oil, and concern over global climate change. As a result, there is renewed interest in biofuels as an alternative to fossil fuels. Africa is uniquely positioned to produce these new cash crops for both domestic use and export. The region has abundant land resources and preferential access to protected markets with higher-than-world-market prices. The rapid growth in the demand for transport fuels in Africa and high fuel prices create domestic markets for biofuels. The European Union and the United States have approved legislation that requires large increases in the consumption of biofuels over at least the next decade. Imports are expected to be needed to meet these mandates, thus opening the door to African and other developing countries that can produce biofuels or feedstocks for biofuels competitively. Expanding the production of crops for biofuels will affect the entire rural sector in Africa as resources are shifted away from traditional crops and the prices of all agricultural commodities rise. Even smallholders can participate in producing biofuel crops. To promote the sustainability and significant contribution of this enterprise, Biofuels in Africa provides guidance in formulating suitable policy regimes, which are based on protecting the rights of current land users, developing revenue-sharing schemes with local communities, safeguarding the environment and biodiversity, expanding institutional capacity, formulating new regulations and procedures, and emulating best practices from experienced countries. This volume will be of value to anyone interested in biofuels, including policy makers, development practitioners, private investors, researchers, and the general public. Now that African countries are trying to significantly increase their energy supply systems, biofuels are an attractive option using both dedicated crops and agricultural waste. This book provides guidance for them to develop a suitable policy regime for a significant contribution by biofuels. -Professor Ogunlade R. Davidson, Minister of Energy and Water Resources, Sierra Leone Biofuels in Africa is a sorely needed resource for our understanding of the problems of expanding biofuels production in Africa. A high point of the book is a description of the projects that were started in several countries. A very useful book! -Professor José Goldemberg, University of São Paulo, Brazil As Africa most likely will play the same role for global biofuels as the Middle East does for oil, this comprehensive book on African biofuels should be compulsory reading for anyone interested in either African development or biofuels. The book captures the essence of long-term drivers and opportunities as well the complex challenges for investors and society of this huge emerging industry. -Per Carstedt, Executive Chairman, EcoEnergy Africa
Biogenic Nano-Particles and their Use in Agro-ecosystems
by Ajit Varma Devendra K. Choudhary Mansour Ghorbanpour Prachi BhargavaSeveral nano-scale devices have emerged that are capable of analysing plant diseases, nutrient deficiencies and any other ailments that may affect food security in agro-ecosystems. It has been envisioned that smart delivery systems can be developed and utilised for better management of agricultural ecosystems. These systems could exhibit beneficial, multi-functional characteristics, which could be used to assess and also control habitat-imposed stresses to crops.Nanoparticle-mediated smart delivery systems can control the delivery of nutrients or bioactive and/or pesticide molecules in plants. It has been suggested that nano-particles in plants might help determine their nutrient status and could also be used as cures in agro-ecosystems. Further, to enhance soil and crop productivity, nanotechnology has been used to create and deliver nano fertilizers, which can be defined as nano-particles that directly help supply nutrients for plant growth and soil productivity. Nano-particles can be absorbed onto clay networks, leading to improved soil health and more efficient nutrient use by crops. Additionally, fertilizer particles can be coated with nano-particles that facilitate slow and steady release of nutrients, reducing loss of nutrients and enhancing their efficiency in agri-crops. Although the use of nanotechnology in agro-ecosystems is still in its early stages and needs to be developed further, nano-particle-mediated delivery systems are promising solutions for the successful management of agri-ecosystems. In this context, the book offers insights into nanotechnology in agro-ecosystems with reference to biogenic nanoparticles. It highlights the: • occurrence and diversity of Biogenic Nanoparticles• mechanistic approach involved in the synthesis of biogenic nanoparticles• synthesis of nanoparticles using photo-activation, and their fate in the soil ecosystem• potential applications of nanoparticles in agricultural systems• application and biogenic synthesis of gold nanoparticles and their characterization• impact of biogenic nanoparticles on biotic stress to plants• mechanistic approaches involved in the antimicrobial effects and cytotoxicity of biogenic nanoparticles• role of biogenic nanoparticles in plant diseases management• relevance of biological synthesized nanoparticles in the longevity of agricultural crops • design and synthesis of nano-biosensors for monitoring pollutants in water, soil and plant systems• applications of nanotechnology in agriculture with special refer to soil, water and plant sciencesA useful resource for postgraduate and research students in the field of plant and agricultural sciences, it is also of interest to researchers working in nano and biotechnology.
Biogeochemistry of the Critical Zone (Advances in Critical Zone Science)
by Adam S. Wymore Wendy H. Yang Whendee L. Silver William H. McDowell Jon ChoroverThis book highlights recent advances in the discipline of biogeochemistry that have directly resulted from the development of critical zone (CZ) science. The earth's critical zone (CZ) is defined from the weathering front and lowest extent of freely circulating groundwater up through the regolith and to the top of the vegetative canopy. The structure and function of the CZ is shaped through tectonic, lithologic, hydrologic, climatic, and biological processes and is the result of processes occurring at multiple time scales from eons to seconds. The CZ is an open system in which energy and matter are both transported and transformed. Critical zone science provides a novel and unifying framework to consider those coupled interactions that control biogeochemical cycles and fluxes of energy and matter that are critical to sustaining a habitable planet. Biogeochemical processes are at the heart of energy and matter fluxes through ecosystems and watersheds. They control the quantity and quality of carbon and nutrients available for living organisms, control the retention and export of nutrients affecting water quality and soil fertility, and influence the ability for ecosystems to sequester carbon. As the term implies, biogeochemical cycles, and the rates at which they occur, result from the interaction of biological, chemical, and physical processes. However, finding a unifying framework by which to study these interactions is challenging, and the different components of bio-geo-chemistry are often studied in isolation. The authors provide both reviews and original research contributions with the requirement that the chapters incorporate a CZ framework to test biogeochemical theory and/or develop new and robust predictive models regarding elemental cycles. The book demonstrates how the CZ framework provides novel insights into biogeochemistry.
