Agroecology is at the forefront of transforming our food systems. This bestselling textbook provides the essential foundation for understanding this transformation in all its components: agricultural, ecological, economic, social, cultural, and political. It presents a case for food system change, explains the principles and practices underlying the ecological approach to food production, and lays out a vision for a food system based on equity and greater compatibility with the planet’s life support systems. New to the fourth edition:
This book addresses the question of the double exposure of marine ecosystems, i.e. to both global climate changes and economic globalization. This book contains a short, but self sufficient mathematical introduction, the formalization in the context of Network economics of global commodity chains, with both trophic and economic processes, and a series of cases studies, going from the re-addressing of fundamental ecological questions such as Gause's exclusion principles to practical studies such as the representation of the global supply chain for tuna.
The introduction and rapid spread of two Eurasian mussel
species, "Dreissena polymorpha "(zebra mussel) and "Dreissena
rostriformis bugensis "(quagga mussel), in waters of North America
has caused great concern among industrial and recreational water
users. These invasive species can create substantial problems for
raw water users such as water treatment facilities and power
plants, and they can have other negative impacts by altering
aquatic environments. In the 20 years since the first edition of
this book was published, zebra mussels have continued to spread,
and quagga mussels have become the greater threat in the Great
Lakes, in deep regions of large lakes, and in the southwestern
Unites States. Quagga mussels have also expanded greatly in eastern
and western Europe since the first book edition was
published.
There has been a deluge of material on biodiversity, starting from a trickle back in the mid-1980's. However, this book is entirely unique in its treatment of the topic. It is unique in its meticulously crafted, scientifically informed, philosophical examination of the norms and values that are at the heart of discussions about biodiversity. And it is unique in its point of view, which is the first to comprehensively challenge prevailing views about biodiversity and its value. According to those dominant views, biodiversity is an extremely good thing - so good that it has become the emblem of natural value. The book's broader purpose is to use biodiversity as a lens through which to view the nature of natural value. It first examines, on their own terms, the arguments for why biodiversity is supposed to be a good thing. This discussion cuts a very broad and detailed swath through the scientific, economic, and environmental literature. It finds all these arguments to be seriously wanting. Worse, these arguments appear to have consequences that should dismay and perplex most environmentalists. The book then turns to a deeper analysis of these failures and suggests that they result from posing value questions from within a framework that is inappropriate for nature's value. It concludes with a novel suggestion for framing natural value. This new proposal avoids the pitfalls of the ones that prevail in the promotion of biodiversity. And it exposes the goals of conservation biology, restoration biology, and the world's largest conservation organizations as badly ill-conceived.
A remarkable look at the rarest butterflies, how global changes threaten their existence, and how we can bring them back from near-extinction Most of us have heard of such popular butterflies as the Monarch or Painted Lady. But what about the Fender’s Blue? Or the St. Francis’ Satyr? Because of their extreme rarity, these butterflies are not well-known, yet they are remarkable species with important lessons to teach us. The Last Butterflies spotlights the rarest of these creatures—some numbering no more than what can be held in one hand. Drawing from his own first-hand experiences, Nick Haddad explores the challenges of tracking these vanishing butterflies, why they are disappearing, and why they are worth saving. He also provides startling insights into the effects of human activity and environmental change on the planet’s biodiversity. Weaving a vivid and personal narrative with ideas from ecology and conservation, Haddad illustrates the race against time to reverse the decline of six butterfly species. Many scientists mistakenly assume we fully understand butterflies’ natural histories. Yet, as with the Large Blue in England, we too often know too little and the conservation consequences are dire. Haddad argues that a hands-off approach is not effective and that in many instances, like for the Fender’s Blue and Bay Checkerspot, active and aggressive management is necessary. With deliberate conservation, rare butterflies can coexist with people, inhabit urban fringes, and, in the case of the St. Francis’ Satyr, even reside on bomb ranges and military land. Haddad shows that through the efforts to protect and restore butterflies, we might learn how to successfully confront conservation issues for all animals and plants. A moving account of extinction, recovery, and hope, The Last Butterflies demonstrates the great value of these beautiful insects to science, conservation, and people.
'Biopiracy' refers either to the unauthorized extraction of biological resources, such as plants with medicinal properties, and associated traditional knowledge from indigenous peoples and local communities, or to the patenting of spurious 'inventions' based on such knowledge or resources without compensation. Biopiracy cases continue to emerge in the media and public eye, yet they remain the source of considerable disagreement, confusion, controversy and grief. The aim of this book is to provide the most detailed, coherent analysis of the issue of biopiracy to date. The book synthesizes the rise of the issue and increasing use of the term by activists and negotiators in the World Trade Organization (WTO) and the Convention on Biological Diversity (CBD), to form a critical understanding of the themes, implications and politics of biopiracy. Taking a case-study based approach, derived from interviews and fieldwork with researchers, government, industry, local farmers, healers and indigenous people, the author sequentially documents events that have occurred in biopiracy and bioprospecting controversies. Implications and ethical dilemmas are explored, particularly relating to work with local communities, and the power relations entailed. Detailing international debates from the WTO, CBD and other fora in an accessible manner, the book provides a unique overview of current institutional limitations and suggests ways forward. Options and solutions are suggested which are relevant for local communities, national governments, international negotiators, NGO and interest groups, researchers and industry.
The International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) is a pivotal piece of recent legislation, providing a route map for the use of such resources for sustainable agriculture and food security. Plant Genetic Resources and Food Security explains clearly the different interests and views at stake between all players in the global food chain. It touches upon many issues such as international food governance and policy, economic aspects of food and seed trade, conservation and sustainable use of food and agricultural biodiversity, hunger alleviation, ecological concerns, consumers' protection, fairness and equity between nations and generations, plant breeding techniques and socio-economic benefits related to food local economies. The book shows that despite the conflicting interests at stake, players managed to come to an agreement on food and agriculture for the sake of food security and hunger alleviation in the world. Published with the Food and Agriculture Organization (FAO) of the United Nations and with Bioversity International.
Humans have moved organisms around the world for centuries but it is only relatively recently that invasion ecology has grown into a mainstream research field. This book examines both the spread and impact dynamics of invasive species, placing the science of invasion biology on a new, more rigorous, theoretical footing, and proposing a concept of adaptive networks as the foundation for future research. Biological invasions are considered not as simple actions of invaders and reactions of invaded ecosystems, but as co-evolving complex adaptive systems with emergent features of network complexity and invasibility. Invasion Dynamics focuses on the ecology of invasive species and their impacts in recipient social-ecological systems. It discusses not only key advances and challenges within the traditional domain of invasion ecology, but introduces approaches, concepts, and insights from many other disciplines such as complexity science, systems science, and ecology more broadly. It will be of great value to invasion biologists analyzing spread and/or impact dynamics as well as other ecologists interested in spread processes or habitat management.
Biodiversity and Ecosystem Insecurity provides an authoritative and comprehensive assessment of the threats presented to human security and well-being by the loss of ecosystems and biodiversity recently confirmed as one of the critical 'planetary boundaries' that has already been exceeded. Contributors examine the current trends and state of biodiversity globally, the drivers of biodiversity loss including climate change and economic and population pressures, and the mechanisms and policies needed for conserving and restoring biodiversity in the future. Strong emphasis is placed throughout on the fundamental importance of placing a realistic economic value on nature and the services that ecosystems provide if we are to manage our natural resources successfully; and also on the crucial role of international institutions and government policies achieving this goal. As the recent high-profile meeting of the Convention on Biological Diversity in Nagoya, Japan, underlined, the scale and pace of the destruction of natural habitats and species imperil us all. This volume is an invaluable resource for conservationists, students and those in the private and public sectors concerned to redress the damage being done to the natural world.

Natural resource governance is central to the outcomes of biodiversity conservation efforts and to patterns of economic development, particularly in resource-dependent rural communities. The institutional arrangements that define natural resource governance are outcomes of political processes, whereby numerous groups with often-divergent interests negotiate for access to and control over resources. These political processes determine the outcomes of resource governance reform efforts, such as widespread attempts to decentralize or devolve greater tenure over land and resources to local communities. This volume examines the political dynamics of natural resource governance processes through a range of comparative case studies across east and southern Africa. These cases include both local and national settings, and examine issues such as land rights, tourism development, wildlife conservation, participatory forest management, and the impacts of climate change, and are drawn from both academics and field practitioners working across the region.

What should the average person know about science? Because science is so central to life in the 21st century, science educators and other leaders of the scientific community believe that it is essential that everyone understand the basic concepts of the most vital and far-reaching disciplines. Biodiversity 101 does exactly that. This accessible volume provides readers -- whether students new to the field or just interested members of the lay public -- with the essential ideas of the origins of humans using a minimum of jargon and mathematics. Concepts are introduced in a progressive order so that more complicated ideas build on simpler ones, and each is discussed in small, bite-sized segments so that they can be more easily understood.
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.
How do we promote global economic development, while simultaneously preserving local biological and cultural diversity? This authoritative volume, written by leading legal experts and biological and social scientists from around the world, aims to address this question in all of its complexity. The first part of the book focuses on biodiversity and examines what we are losing, why and what is to be done. The second part addresses biotechnology and looks at whether it is part of the solution or part of the problem, or perhaps both. The third section examines traditional knowledge, explains what it is and how, if at all, it should be protected. The fourth and final part looks at ethnobotany and bioprospecting and offers practical lessons from the vast and diverse experiences of the contributors.
This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.
This practical handbook describes sampling and laboratory assessment methods for the biodiversity of a number of key functional groups of soil organisms, including insects, earthworms, nematodes, fungi and bacteria. The methods have been assembled and the protocols drafted by a number of scientists associated with the UNEP-GEF funded Conservation and Sustainable Management of Below-Ground Biodiversity project, executed by the Tropical Soil Biodiversity and Fertility (TSBF) institute of the International Center for Tropical Agriculture (CIAT). The methods provide a standardized basis for characterizing soil biodiversity occurring in terrestrial natural and agro-ecosystems in the tropics and current land uses in forest and forest margin areas. The aim is to assess soil biodiversity against current and historic land use practices both at plot and landscape scales and further to identify opportunities for improved sustainable land management through the introduction and/or management of soil biota, thus reducing the need for external inputs such as fertilizers and pesticides. The book does not contain identification keys as such, but there is extensive advice on the handling of specimens and the allocation of organisms to strain or functional group type.Published with TSBF-CIAT.
This book combines several ideas and philosophies and provides a detailed discussion on the value addition of fruits, vegetables, spices, plantation crops, floricultural crops and in forestry. Separate chapters address the packaging, preservation, drying, dehydration, total quality management and supply chain management of horticultural crops. The book explains value addition as a process of increasing the economic value and consumer appeal of a commodity with special reference to horticultural crops. Each chapter focuses on a specific area, exploring value addition as a production/ marketing strategy driven by customer needs and preferences. But, as such, it is also a more creative field, calling for more imagination than calculated, routine work. Value is added to the particular produce item when the product is still available when the season is out and the demand for the product exceeds the available supply. Value addition is an important factor in the growth and development of the horticultural sector, both in India and around the world. But very little information is available on this particular aspect of horticulture. Albert Einstein famously said, "Try not to become a man of success, but rather try to become a man of value." This message is not only true for those people who want to make more of themselves, but also for those who want their creation or product in any form to excel. And it certainly applies to horticultural crops, which are extremely perishable. It is true that loss reduction is normally less costly than equivalent increases in production. The loss of fresh produce can be minimized by adopting different processing and preservation techniques to convert the fresh vegetables into suitable value-added and diversified products, which will help to reduce the market glut during harvest season. Value-added processed products are products that can be obtained from main products and by-products after some sort of processing and subsequently marketed for an increased profit margin. Generally speaking, value-added products indicate that for the same volume of primary products, a higher price is achieved by means of processing, packing, enhancing the quality or other such methods. The integrated approach from harvesting to the delivery into the hands of the consumer, if handled properly, can add value to fresh produce on the market. But most of the fresh produce has a limited life, although it can be stored at appropriate temperature and relative humidity for the same time. If such produce is processed just after harvesting, it adds value and stabilizes the processed products for a longer time. Preparing processed products will provide more variety to consumers and improve the taste and other sensory properties of food. This will also promote their fortification with nutrients that are lacking in fresh produce. By adopting suitable methods for processing and value addition, the shelf life of fresh produce can be increased manifold, which supports their availability year-round to a wider spectrum of consumers on both the domestic and international market. With increased urbanization, rising middle class purchasing power, changing food habits and a decline in making preserved products in individual homes, there is now a higher demand for industry-made products on the domestic market. In spite of all these aspects, only 1-2.2% of the total produce is processed in developing countries, as compared to 40-83% in developed countries. The horticultural export industry offers an important source of employment for developing countries. For instance, horticulture accounts for 30% of India's agricultural GDP from 8.5% of cropped area. India is the primary producer of spices, second largest producer of fruits and vegetables and holds a prominent position with regard to most plantation crops in the world. The cultivation of horticultural crops is substantially more labor-intensive than growing cereal crops and offers more post-harvest opportunities for the development of value-added products. This book offers a valuable guide for students of horticulture, as well as a comprehensive resource for educators, scientists, industrial personnel, amateur growers and farmers.
Natural forests with thousands of years of ecological continuity are unrivalled as the treasure store of terrestrial biodiversity on Earth. And while there is currently no fully comprehensive inventory of the biota associated with any given forest, it is reasonable to assume that in conserving natural forests we can conserve the myriads of unnamed bacteria, fungi, insects, mites and nematodes that forests support. Drawing on diverse research from biodiversity experts around the world, this collection of papers reflects the diversity of forest types and forest issues that concern forest scientists globally. Forest types considered vary from savannah and tropical rainforests to the ancient oak forests of Poland; issues explored include the effects of logging, management practices, forest dynamics and climate change on forest structure and biodiversity. Given the range of topics covered, this book should be of particular interest to those involved in teaching forest conservation and management, as well as to researchers requiring an overview of current work in forest diversity, conservation and sustainable management.

'This book has been written by a team of experts from a wide variety of institutions... The result is by far the most comprehensive and easy to understand treatment of FLR yet written.' ACHIM STEINER (DIRECTOR GENERAL, IUCN) AND MANOEL SOBRAL FILHO (EXECUTIVE DIRECTOR, ITTO), FROM THE PREFACE Forest loss and degradation have caused a decline in the quality of ecosystem services around the world. But fixing the problem takes more than just planting trees; practitioners increasingly realize that a landscape approach is essential. This handbook, authored and edited by international authorities in the field of forestry, is the first practical guide to using forest landscape restoration (FLR) to repair the damage done to forest lands by poor land management practice. Using research backed by respected institutions such as ITTO and the World Conservation Union (IUCN), it explains how to increase the resilience of landscapes and the communities they support through FLR. The main aim of FLR is not to re-establish pristine forest, even if this were possible; rather, the objective is to make landscapes more resilient and thereby keep future management options open. It also aims to support communities as they strive to increase and sustain the benefits they derive from land management. This book explains the concept of FLR and guides the reader through the steps that must be taken to put it into practice. It is an indispensable aid for practitioners in all aspects of forestry and natural resource management. Published with ITTO and IUCN
The RSPB's Book of the Season The distinctive white-tailed sea eagle was driven to extinction in Britain more than 200 years ago, but this immense predator is making a return to our skies, thanks to Roy Dennis, an ornithologist, conservationist and arguably the driving force behind the UK's reintroduction agenda. Roy was instrumental in returning the Osprey, red kite and golden eagle to the British Isles, but the road to reintroduction isn't an easy one. In what will surely be the seminal book on British reintroductions, Roy details the painstaking process of returning the Goldeneye to Scotland, one duckling at a time, the die-hard determination needed to make a dazzling success of the red kite reintroduction and the leap of faith we will all need to make to accept sharing our forests and skies with large carnivores again. He also illustrates all that we have to gain by restoring our ecosystems to balance. Filled with a lifetime's worth of stories from the front lines of conservation, Reintroduction offers an eye-opening insight into the complexities of reintroducing extinct animals to Britain. It's also an intimate portrait of these apex predators and a reminder of why we need them. |
