There is also a list of invasive species, with their countries of origin and regions of introduction.

Ecohydrology of the Andes Paramo Region (Paperback): Veronica G. Minaya Maldonado Ecohydrology of the Andes Paramo Region (Paperback)
Veronica G. Minaya Maldonado
R2,717 Discovery Miles 27 170 Ships in 12 - 17 working days

In the Andes mountainous region of South America grasslands known as paramos provide important ecosystem services like sustaining biodiversity, securing carbon sequestration and providing water storage. However, many paramos regions are subject to land use change due to expanding agriculture, intensified grazing and land burning. These are usually caused by socio-economic factors driving local communities to increase their income generation. Trying to achieve a better understanding of the paramos is often restricted to exploring specific details and does not follow an integrated approach or a comprehensive ecosystem analysis. In this research the focus is on better understanding the dominant ecohydrological processes and their interactions. An integrated approach is followed using in-situ measurements, field experiments, laboratory analyses, and numerical modelling. Also, different hydroinformatics tools are used to identify and quantify the ecosystem services provided by the paramos. Moreover, a framework is developed that allows a more realistic quantification and mapping of the main ecosystem services. The approach was carried out for a test site in an Ecological area in North Ecuador. The findings show a clear difference in ecosystem services depending on their altitudinal range and type of vegetation. These results can be used to further develop environmental management and landscape planning strategies, in order to better meet the social goals. This research is aligned with the priorities advocated in the IPCC Report (2007) 'to improve representation of the interactive coupling between ecosystems and the climate system', and with SDG #15: Life on Land 'By 2020, ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services'.

The Root Causes of Biodiversity Loss (Hardcover): Alexander Wood, Pamela Stedman-Edwards, Johanna Mang The Root Causes of Biodiversity Loss (Hardcover)
Alexander Wood, Pamela Stedman-Edwards, Johanna Mang
R4,595 Discovery Miles 45 950 Ships in 12 - 17 working days

The world is losing species and biodiversity at an unprecedented rate. The causes go deep and the losses are driven by a complex array of social, economic, political and biological factors at different levels. Immediate causes such as over-harvesting, pollution and habitat change have been well studied, but the socioeconomic factors driving people to degrade their environment are less well understood. This book examines the underlying causes. It provides analyses of a range of case studies from Brazil, Cameroon, China, Danube River Basin, India, Mexico, Pakistan, Philippines, Tanzania and Vietnam, and integrates them into a new and interdisciplinary framework for understanding what is happening. From these results, the editors are able to derive policy conclusions and recommendations for operational and institutional approaches to address the root causes and reverse the current trends. It makes a contribution to the understanding of all those - from ecologists and conservationists to economists and policy makers - working on one of the major challenges we face.

Mining and the Environment - International Perspectives on Public Policy (Hardcover): Roderick G. Eggert Mining and the Environment - International Perspectives on Public Policy (Hardcover)
Roderick G. Eggert
R1,222 Discovery Miles 12 220 Ships in 12 - 17 working days

For centuries, denuded landscapes, fouled streams, and dirty air were accepted by society as part of the price that had to be paid for mineral production. Even initial environmental legislation devised by industrialized countries in the 1960s and 1970s was largely designed without mining in mind. And developing countries had little in the way of environmental policy. With the advent of sustainability in the 1990s, times have changed. Today's economic development, many now feel, must not come at the expense of an environmentally degraded future. Current policies toward mining are under rigorous review, and mineral-rich developing countries are designing environmental policies where none existed before. In Mining and the Environment, noted analysts offer viewpoints from Australia, Chile, the United Kingdom, the United States, and the European community on issues and challenges of metal mining.

Insect Bioecology and Nutrition for Integrated Pest Management (Paperback): Antonio Ricardo Panizzi, Jose R. P. Parra Insect Bioecology and Nutrition for Integrated Pest Management (Paperback)
Antonio Ricardo Panizzi, Jose R. P. Parra
R2,732 Discovery Miles 27 320 Ships in 12 - 17 working days

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: General Aspects: Basic bioecology and insect nutrition; artificial diets; insect/plant interactions; insect symbionts; the interface of chemical ecology with the food; and insect cannibalism Specific Aspects: Specific feeding guilds of insects including ants, social bees, leaf chewers, seed suckers, seed chewers, root feeders, gall makers, detritivorous feeders, pests of storage grains, fruit flies, aphids, endo- and ectoparasitoids, predators, crisopids, and hematophagous insects Applied Aspects: Host plant resistance and the design of IPM programs in the context of insect bioecology and nutrition 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.

Species Richness - Patterns in the Diversity of Life (Hardcover, 2009 ed.): Jonathan Adams Species Richness - Patterns in the Diversity of Life (Hardcover, 2009 ed.)
Jonathan Adams
R5,977 Discovery Miles 59 770 Ships in 10 - 15 working days

This is a readable, informative and up-to-date account of the patterns and controls on biodiversity. The author describes major trends in species richness, along with uncertainties in current knowledge. The various possible explanations for past and present species patterns are discussed and explained in an even-handed and accessible way. The implications of global climate change and habitat loss are considered, along with current strategies for preserving what we have. This book examines the state of current understanding of species richness patterns and their explanations. As well as the present day world, it deals with diversification and extinction, in the conservation of species richness, and the difficulties of assessing how many species remain to be discovered. The scientifically compelling subject of vegetation-climate interaction is considered in depth. Written in an accessible style, the author offers an up-to-date, rigorous and yet eminently comprehensible overview of the ecology and biogeography of species richness. He departs from the often heavy approach of earlier texts, without sacrificing rigor and depth of information and analysis. Prefacing with the aims of the book, Chapter 1 opens with an explanation of latitudinal gradients, including a description of major features of the striking gradients in species richness, exceptions to the rule, explanations, major theories and field and experimental tests. The following chapter plumbs the depth of time, including the nature of the fossil record, broad timescale diversity patterns, ecosystem changes during mass extinctions and glaciations and their influence on species richness. Chapters 3 and 4 consider hotspots and local scale patterns in species richness while Chapter 5 looks at the limitations and uncertainties on current estimates of richness, the last frontiers of species diversity and the process of identifying new life forms. The last three chapters cover humans and extinctions in history and prehistory, current habitat and global change, including the greenhouse effect, and the race to preserve what we still have, including parks, gene banks and laws.

African Indigenous Vegetables in Urban Agriculture (Hardcover): Charlie M. Shackleton, Margaret W. Pasquini, Axel W. Drescher African Indigenous Vegetables in Urban Agriculture (Hardcover)
Charlie M. Shackleton, Margaret W. Pasquini, Axel W. Drescher
R4,583 Discovery Miles 45 830 Ships in 12 - 17 working days

This book provides a comprehensive synthesis of current knowledge of the potential and challenges associated with the multiple roles, use, management and livelihood contributions of indigenous vegetables in urban agriculture in sub-Saharan Africa. There has been growing research and policy effort around urban agriculture in the region over the last two decades, but never has it been integrated with work on under-researched crops such as indigenous vegetables. These species have multiple advantages, including low input requirements, adaptability to African environments, high nutritional value and marked biodiversity, cultural and local food security significance. Yet they are overlooked in the modern world, where recent emphasis has been directed to growing a limited range of exotic crops, both for internal markets and for export to developed country markets. This book provides evidence that, in spite of this neglect, in many African cities indigenous vegetables are still widely used, cultivated and marketed. It goes on to consider their potential to contribute to income generation and poverty alleviation of the growing numbers of urban dwellers in sub-Saharan Africa, whilst promoting urban greening and sustainability. Based on critical analysis of the debates it presents a multidisciplinary analysis of the realities and future opportunities.

Future Nature - A Vision for Conservation (Hardcover, 2nd edition): W. M. Adams Future Nature - A Vision for Conservation (Hardcover, 2nd edition)
W. M. Adams
R4,576 Discovery Miles 45 760 Ships in 12 - 17 working days

The countryside is changing faster than ever. Fifty years of conservation achievements in the UK are now being confronted by a new complexion of economic forces that are driving change in the countryside. At the same time new ideas in conservation are altering the role that conservation is being asked to play in negotiating the transition from past to future. This revised edition of Bill Adams classic work Future Nature tackles the new challenges in the countryside and wildlife conservation head-on through a new Introduction and Postscript with updated arguments about naturalness and our social engagement with nature, and complemented by a new Foreword by Adrian Phillips. Concepts such as biodiversity and sustainability, and changes in our understanding, appreciation and concern for nature, offer unprecedented opportunities. Bill Adams explores the scientific, cultural and economic significance of conservation. He argues that conservation must move beyond the boundaries of parks and reserves to embrace the whole countryside. The importance of conservation for the future is enormous. It holds the potential to create new spaces for nature, both in the landscape and in our lives and imaginations. This factual, beautifully written and thought-provoking book offers a fundamental reassessment of conservation, its importance, and how to achieve it. Published with BANC

Our Common Seas - Coasts in Crisis (Paperback): Don Hinrichsen Our Common Seas - Coasts in Crisis (Paperback)
Don Hinrichsen
R1,028 Discovery Miles 10 280 Ships in 12 - 17 working days

Most of the world's population lives on or near the coasts. Every nation not completely landlocked has used the sea as its supposedly self-cleansing garbage dump. Now the effects are being felt. There is not a coast in the world which is not dangerously polluted. Sewage, oil, plastics, industrial effluents, radioactive waste have been added to ungoverned development, all of which are busily destroying otherwise robust inshore eco-systems. Hinrichsen, basing his work on United Nations Environment Programme (UNEP) research and his own extensive travels, has described the situation in the Mediterranean, the Gulf, the Indian Ocean, the South-East Asian Seas and the Eastern Pacific. He covers both the disasters and the growing successes in dealing with them, and he points the way to the sort of international deal needed to rescue a vast resource in danger of complete destruction. His book is both a call to action and a sign of hope. Originally published in 1990

The Politics of Knowledge and Global Biodiversity (Paperback): Alice Vadrot The Politics of Knowledge and Global Biodiversity (Paperback)
Alice Vadrot
R1,525 Discovery Miles 15 250 Ships in 12 - 17 working days

The establishment of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) points to the crucial role attributed to science and knowledge for the successful implementation of biodiversity politics by both scientists and policy-makers. With the increased importance of biodiversity in international politics, and in part inspired by the success the Intergovernmental Panel on Climate Change (IPCC) has had in raising awareness of global warming, the call for an 'IPCC for Biodiversity' was successful. The Politics of Knowledge and Global Biodiversity gives a full overview of the process of its implementation as finalised in 2013 and proposes an innovative conceptual framework that puts this specific case into a more general perspective of international politics and relations. It provides a detailed empirical analysis of the knowledge politics associated with the establishment of IPBES and its conceptual framework and methodological approach is grounded in a theoretical perspective. This pioneering work is the first to examine IPBES in this way and is essential reading for researchers and scholars of International Relations, Environmental and Biodiversity Politics, Science-Policy Interfaces and Global Environmental Governance. It will also be of interest to political scientists and social scientists.

Managing Upland Resources - New Approaches for Rural Environments (Hardcover): Lois Mansfield Managing Upland Resources - New Approaches for Rural Environments (Hardcover)
Lois Mansfield
R1,588 Discovery Miles 15 880 Ships in 12 - 17 working days

Many traditional approaches to rural land management are strictly sectoral, with a rigid introspective focus. Consequently the impact of silo-driven change on other land users they can often be overlooked or not appreciated. This book critically reviews why there has yet to be a clear route to upland resource management and provides insight and options for integrated transdisciplinary land management solutions for rural areas, specifically uplands. It considers the problem in order to derive appropriate solutions enhanced by a number of in-depth case studies by resource management professionals and the use of many examples of contemporary good practice from different uplands, organisations, projects and programmes.The overarching approach of the book is to provide a tool kit for those individuals, groups or organisations looking to manage the upland resource for the benefit of all. Readers are provided with a range of practical options to develop their own solutions. The book is written in such a way that readers can dip in and out of sections to plug knowledge gaps or read in its entirety for those experiencing a first foray into the complexities of upland resource management.Increasingly, rural areas are becoming recognised as a wider resource beyond traditional food, fibre and water, leading to inevitable management tensions. Goal setting, vision and strategy development, management planning, aims, objectives and prescription (actions) are considered and some of the new agendas for resource use in uplands which may be worth consideration for individual projects are explored. This comprehensive book deals with the implementation, advantages and disadvantages of a range of traditional and contemporary resource management approaches which are then expanded upon by a range of resource management professionals based on their own experiences. These case studies demonstrate the development of more effective projects and the book concludes by considering how work can be monitored and evaluated before ideas are synthesised for best practice.

Routledge Handbook of Ecosystem Services (Hardcover): Marion Potschin, Roy Haines Young, Robert Fish, R.Kerry Turner Routledge Handbook of Ecosystem Services (Hardcover)
Marion Potschin, Roy Haines Young, Robert Fish, R.Kerry Turner
R7,233 Discovery Miles 72 330 Ships in 12 - 17 working days

The idea that nature provides services to people is one of the most powerful concepts to have emerged over the last two decades. It is shaping our understanding of the role that biodiverse ecosystems play in the environment and their benefits for humankind. As a result, there is a growing interest in operational and methodological issues surrounding ecosystem services amongst environmental managers, and many institutions are now developing teaching programmes to equip the next generation with the skills needed to apply the concepts more effectively. This handbook provides a comprehensive reference text on ecosystem services, integrating natural and social science (including economics). Collectively the chapters, written by the world's leading authorities, demonstrate the importance of biodiversity for people, policy and practice. They also show how the value of ecosystems to society can be expressed in monetary and non-monetary terms, so that the environment can be better taken into account in decision making. The significance of the ecosystem service paradigm is that it helps us redefine and better communicate the relationships between people and nature. It is shown how these are essential to resolving challenges such as sustainable development and poverty reduction, and the creation of a green economy in developing and developed world contexts.

Mushrooms in Forests and Woodlands - Resource Management, Values and Local Livelihoods (Paperback): Anthony B. Cunningham, Xue... Mushrooms in Forests and Woodlands - Resource Management, Values and Local Livelihoods (Paperback)
Anthony B. Cunningham, Xue Fei Yang
R1,557 Discovery Miles 15 570 Ships in 12 - 17 working days

Many mushrooms - or the 'fruits of fungi' - are extremely valuable, wild-gathered products which are utilised for both their medicinal properties and as food. In many of the world's tropical and temperate forests, they are the primary source of income for the people who live there. These forests range from temperate woodlands and small forests to high altitude forests in the Himalaya and tropical miombo woodlands in south-central Africa. In south-west China, over 200 species of wild fungi in 64 genera are commercially traded while in Europe and North America, woodlands and small forests are the source of many highly-prized mushrooms and an essential resource for many small enterprises and collectors. Yet the increased demand for timber has resulted in the rapid expansion of forestry, which in turn has destroyed the natural habitat of many fungi, unbalancing both forest economics and ecology. Despite the economic, social and cultural values of fungi, there is a general lack of understanding of their importance to local livelihoods and forest ecology. This book aims to fill this gap and extends the People and Plants Conservation Series beyond the plant kingdom into the related world of fungi and mushrooms. It demonstrates the crucial roles that fungi play in maintaining forest ecosystems and the livelihoods of rural people throughout the world while providing good practice guidelines for the sustainable management of this resource and an assessment of economic value. It brings together the perspectives of biologists, anthropologists and forest and woodland managers to provide a unique inter-disciplinary and international overview of the key issues.

Plant Resources for Food, Fuel and Conservation (Paperback): Robert James Henry Plant Resources for Food, Fuel and Conservation (Paperback)
Robert James Henry
R1,518 Discovery Miles 15 180 Ships in 12 - 17 working days

Agriculture and food production have a large footprint on the landscape globally and compete for space with land for nature conservation. This book explores the competition between the food needs of a growing human population and the conservation of biodiversity as intensified by the emerging use of crops for energy production. As concern about the impact of greenhouse gas emissions on climate grows and oil prices increase, energy production from agricultural crops has become a significant industry. At the same time, growth in food demand due to population growth has been accelerated by growing affluence associated with economic growth in major developing countries increasing per capita consumption. Consumers are concerned that the price of food will continue to increase sharply as a result of this competition but a loss of biodiversity may be another major outcome. Drawing on his expertise in plant conservation genetics, the author provides a balanced appraisal of the potential for developing new or improved crops for food or bioenergy production in the context of climate change, while at the same time protecting biodiversity.

R3,044 Discovery Miles 30 440 Ships in 10 - 15 working days

Indian screw pine family Pandanaceae represents three genera, in which genus Pandanus and Benstonea are distributed in two hotspots in India the Western Ghats and the Northeast Himalayan region. For the first time, Indian Pandanaceae has been assessed for its taxonomic status and phylogenetic relationship. The extensive survey by the authors led to the discovery of three new Pandanus species (two from the Western Ghats and one from the Northeast Himalaya). The present taxonomic revision confirmed total number of Pandanus species to 14 that are distributed in the Southern India (9 species) and Northeast Himalayan region (5 species). Genus Benstonea is represented by two species, one from Southern India and another species common to both regions. A detailed species identification key is given along with conservation status of each species following IUCN Red List Categories and Criteria (2001). The study revealed that, out of 16 Pandanus and Benstonea species, six species are under threatened categories.

In recent years, a chloroplast DNA-based molecular phylogenetic approach has been followed to understand the evolutionary relationship among the plant species. The interrelationship among the 14 Pandanus species at infrageneric level has been worked out using this approach, which has led to the rearrangement of some species to the subgenera proposed by Stone (1974). Moreover, the close relationship between Pandanus and Benstonea has been confirmed and the interrelationship of Indian Pandanus genus in global context is given. This book also describes the economic importance of each Pandanus species.

Unstructured Cellular Automata in Ecohydraulics Modelling (Paperback): Yuqing Lin Unstructured Cellular Automata in Ecohydraulics Modelling (Paperback)
Yuqing Lin
R1,385 Discovery Miles 13 850 Ships in 12 - 17 working days

The field of ecohydraulics integrates hydrodynamic and eco-dynamic processes. While hydrodynamic processes are usually well described by partial differential equations (PDE's) based on physical conservation principles, ecosystem dynamics often involve specific interactions at the local scale. Because of this, Cellular Automata (CA) are a viable paradigm in ecosystem modelling. All cells in a CA system update their states synchronously at discrete steps according to simple local rules. The classical CA configuration consists of uniformly distributed cells on a structured grid. But in the field of hydrodynamics, the use of unstructured grids has become more and more popular due to its flexibility to handle arbitrary geometries. The main objective of this research is to identify whether the CA paradigm can be extended to unstructured grids. To that end the concept of Unstructured Cellular Automata (UCA) is developed and various UCA configurations are explored and their performance investigated. The influence of cell size was analyzed in analogy with the Finite Volume Method. A characteristic parameter -min distance of UCA- was put forward and tested by numerical experiments. Special attention was paid to exploring the analogies and differences between the discrete CA paradigm and discrete numerical approximations for solving PDE's. The practical applicability of UCA in ecohydraulics modelling is explored through a number of case studies and compared with field measurements.

Marine Biodiversity, Climatic Variability and Global Change (Hardcover): Gregory Beaugrand Marine Biodiversity, Climatic Variability and Global Change (Hardcover)
Gregory Beaugrand
R5,991 Discovery Miles 59 910 Ships in 12 - 17 working days

Biodiversity loss in terrestrial environments associated with human activities has been appreciated as a major issue for some years now. What is less well documented is the effect of such activities, including climate change, on marine biodiversity. This pioneering book is the first to address this important but neglected topic, which is likely to be the key challenge for marine scientists in the near future. Using a multidisciplinary and a holistic approach, the book reveals how climatic variability controls biodiversity at time scales ranging from synoptic meteorological events to millions of years and at spatial scales ranging from local sites to the whole ocean. It shows how global change, including anthropogenic climate change, ocean acidification and more direct human influences such as exploitation, pollution and eutrophication may alter biodiversity, ecosystem functioning and regulating and provisioning services. The author proposes a theory termed the 'macroecological theory on the arrangement of life', which explains how biodiversity is organized and how it responds to climatic variability and anthropogenic climate change. The book concludes with recommendations for further research and theoretical development to identify oceanic areas in need of observation and gaps in current scientific knowledge. Many references and comparisons with the terrestrial realm are included in all chapters to better understand the universality of the relationships between biodiversity, climate and the environment. The book will serve as a textbook for all students and researchers of marine science and environmental change, but will also be accessible to the more general reader.
