  • The world is changing quickly, and our models of learning, communicating, and acting must change accordingly. Throughout society we must rethink basic notions of how we define and accomplish our goals in a complex and changing environment, including how we prepare ourselves for professional careers. This book is an effort in that direction for students in natural resource management. It is a response to some of the challenges we perceive students will face in the early twenty-first century, and it is a practice field on which they may begin to develop their skills....

  • The Current State and Trends assessment presents the findings of the Condition and Trends Working Group of the Millennium Ecosystem Assessment. This volume documents the current condition and recent trends of the world’s ecosystems, the services they provide, and associated human well-being around the year 2000. Its primary goal is to provide decision-makers, ecosystem managers, and other potential users with objective information and analyses of historical trends and dynamics of the interaction between ecosystem change and human well-being.

  • The focus of the MA is on ecosystem services (the benefits people obtain from ecosystems), how changes in ecosystem services have affected human well-being in the past, and what role these changes could play in the present as well as in the future. The MA is an assessment of responses that are available to improve ecosystem management and can thereby contribute to the various constituents of human well-being. The specific issues addressed have been defined through consultation with the MA users.

  • This volume, edited by John Gunn, Rob Steedman, and Dick Ryder, pulls together an incredibly broad mix of people and topics under a single cover. As such, it is a worthy addition to the new series from CRC Press — Integrative Studies in Water Management and Land Development — that was initiated in 2002 with publication of my own edited volume, Handbook of Water Sensitive Planning and Design . Books like these are rare, but they shouldn’t be.

  • Remote sensing has been defined as the detection, recognition, or evaluation of objects by means of distant sensing or recording devices. In recent decades, remote sensing technology has emerged to support data collection and analysis methods of potential interest and importance in forest management. Historically, digital remote sensing developed quickly from the technology of aerial photography and photointerpretation science. In forestry, information extracted visually from aerial photographs is well-understood, well-used, and integrated with field surveys.

  • The primary purpose of preparing this edition is to provide an update. In the 14 years since the first edition was published, ecological risk assessment has gone from being a marginal activity to being a relatively mature practice. There are now standard frameworks and guidance documents in the United States and several other countries. Ecological risk assessment is applied to the regulation of chemicals, the remediation of contaminated sites, the importation of exotic organisms, the management of watersheds, and other environmental management problems....

  • Natural resources conservation is one of the dilemmas currently facing mankind in both developed and the developing world. The topic is of particular importance for the latter, where the majority depend on terrestrial ecosystems for livelihood; more than one billion people live in abject poverty earning less than a dollar per day; more than 3.7 billion suffer from micronutrient deficiency and more than 800 million suffer from chronic hunger.

  • Urban Ecology is the study of ecosystems that include humans living in cities and urbanizing landscapes. It is an emerging, interdisciplinary field that aims to understand how human and ecological processes can coexist in human-dominated systems and help societies with their efforts to become more sustainable. It has deep roots in many disciplines including sociology, geography, urban planning, landscape architecture, engineering, economics, anthropology, climatology, public health, and ecology.

  • The concept of forest sustainability dates from centuries ago, although the understanding of sustainable forest management (SFM) as an instrument that harmonizes ecological and socio-economic concerns is relatively new. The change in perspective occurred at the beginning of the 1990s in response to an increased awareness of the deterioration of the environment, in particular of the alarming loss of forest resources. The main and most striking cause of this deterioration is the deforestation occurring in some areas of the world.

  • The science of ecology and the practice of management are critical to our understanding of the Earth’s ecosystems and our efforts to conserve them. This book attempts to bridge the gap between ecology and natural resource management and, in particular, focuses on the discipline of plant ecology as a foundation for vegetation and wildlife management. It describes how concepts and approaches used by ecologists to study communities and ecosystems can be applied to their management. Guy R.

  • Compared to other ecosystems, wetlands have received an exceptional amount of attention. Wetlands are valuable as sources, sink and transformers of a multitude of chemical, biological and genetic materials. They stabilize water supplies, clean polluted waters, protect shorelines, and recharge groundwater aquifers. They have increasingly become recognized for their unique ecological functions in the environment and are the focus of increased research by scientists and study programs by schools, communities, and nature centers.

  • The growth of Aquaculture and its future role as a food supplier to human society has environmental, social and economic limitations, affecting marine ecosystems and socio-economic scales from local to global. These are close links with human health requirements and societal needs for various goods and services provided by marine ecosystems. This book shows this broad spectrum of dependencies of the future growth of aquaculture and highlights both relevant problems and expectations.

  • It was not until the eighteenth century that the subject of this book, the pollination services of bees, began to be understood and valued. Nevertheless, the association between man and bees has been long and close, and dates from at least 2400 BC. Beekeeping with the Western honey bee, Apis mellifera, was a well-developed craft in ancient Egypt during the fi fth dynasty of the Old Kingdom.

  • Challenges to sustaining the productivity of oceanic and coastal fisheries have become more critical and complex as these fisheries reach the upper limits to ocean harvests. In addition, it is now clear that we are managing interactive and dynamic food webs rather than sets of independent single-species populations.
