World human population is expected to reach upwards of 9 billion by 2050 and then level off over the next half-century. How can the transition to a stabilizing population also be a transition to sustainability? How can science and technology help to ensure that human needs are met while the planet's environment is nurtured and restored? Our Common Journey examines these momentous questions to draw strategic connections between scientific research, technological development, and societies' efforts to achieve environmentally sustainable improvements in human well being. The book argues that societies should approach sustainable development not as a destination but as an ongoing, adaptive learn...

Return to the River will describe a new ecosystem-based approach to the restoration of salmon and steelhead populations in the Columbia River, once one of the most productive river basins for anadromous salmonids on the west coast of North America. The approach of this work has broad applicability to all recovery efforts throughout the northern hemisphere and general applicability to fisheries and aquatic restoration efforts throughout the world. The Pacific Northwest is now embroiled in a major public policy debate over the management and restoration of Pacific salmon. The outcome of the debate has the potential to affect major segments of the region's economy - river transportation, hydroe...
Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.
What has happened to the salmon resource in the Pacific Northwest? Who is responsible and what can be done to reverse the decline in salmon populations? The responsibly falls on everyone involved - fishermen, resource managers and concerned citizens alike - to take the steps necessary to ensure that salmon populations make a full recovery. T
The human-environment relationship - intimately intertwined and often contentious - is one of the most pressing concerns of the 21st century. Explored through an array of critical approaches, this book brings together case studies from across the globe to present significant cutting-edge research into political ecologies as they relate to multi-form contestations over environments, resources and livelihoods. Covering a range of issues, such as popular discourses of environmental 'collapse', climate change, water resource struggles, displacement, agro-food landscapes and mapping technologies, this edited volume works to provide a broad and critical understanding of the narratives and policies more subtly shaping and being shaped by underlying environmental conflicts. By exploring the power-laden processes by which environmental knowledge is generated, framed, communicated and interpreted, Contentious Geographies works to reveal how environmental conflicts can be (re)considered and thus (re)opened to enhance efforts to negotiate more sustainable environments and livelihoods.
Fisheries and Aquaculture theme is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Fisheries are a major life support system and the main purpose of this theme on Fisheries and Aquaculture is to provide baseline information and latest knowledge at the dawn of this century to facilitate vital fisheries recovery before their irreparable collapse. This Theme on Fisheries and Aquaculture is divided into five topics. It starts with discussions on major issues and challenges in “Harvesting the Seas”, with emphasis on the ...
"Increasing coastal populations, rising recreational demand, and growing conflicts with other users are adding to the challenge of managing marine recreational fisheries today. Traditional regulations - such as daily bag limits and seasonal closures - are often not enough to control fishing impacts and they tend to generate greater discontent and lower economic benefits in the angling community as they become more restrictive. This volume is the first to examine management approaches that promise to better control fishing, generate more information on fishing impacts, and give anglers more freedom to enjoy their sport."--BOOK JACKET.
