Book excerpt: Bristol Bay, Alaska is one of the last ecosystems left on earth that haqs gone unaltered by human impacts. Bristol Bay watershed supports the largest wild sockeye salmon runs on the planet with nearly 42 million salmon migrating to the watersheds headwaters every year. The proposed Pebble Mine, containing gold, copper, and molybdenum has threatened the health of this watershed. This project asks what effects the proposed Pebble Mine will have on water quality and quantity, and more specifically, how the withdrawal of groundwater and surface water will alter the regions most pristine anadromous salmonid spawning grounds. Though comprehensive studies have been done, the groundwater of this region remains a comples topic. This research formulates unanswered questions related to groundwater that need to be answered before mining advances. Due to the unknown properties of the region's groundwater and hydrologic regime, mining poses significant risk to water quality, quantity, and aquatic species of the Bristol Bay watershed.

Book excerpt: Public policies are created through an intricate network of advocacy coalitions and policy brokers within public and private networks who seek to change or enhance current policy. The focus of this thesis research is a rarely used authority of the Environmental Protection Agency granted under the Clean Water Act Section 404(c) to prohibit or restrict dredge and fill activity in the Bristol Bay watershed in the Southwest region of Alaska based on anticipated impacts of large-scale mining activity. Those who fish in Bristol Bay, whether for subsistence, recreational or commercial purposes want to prohibit or restrict large-scale mining activity like the proposed Pebble Mine in the region. If built, Pebble Mine would be one of the world's largest open-pit mines with mineral values estimated to exceed $500 billion at the estimated building cost of $6 billion, not to mention the cost of environmental impacts to the Bristol Bay ecosystem. Some who write about development and its environmental impact seem to advocate for collaborative subsystems to promote policy learning and change, however, the Pebble Mine conflict - having a clear winner and loser - reflects how adversarial subsystems interact. Mark Smith's (2009) environmental flow policy analysis of advocacy coalitions is a useful framework to use to understand the Save Bristol Bay coalition formation and strategy. The coalition used science for intra-coalition cooperation and for policy advocacy. Through the coalition's efforts, protecting Bristol Bay moved beyond the public agenda and reached the formal agenda for policy decision-makers. In this thesis research I provide a brief background of the issue, identifying the stakeholders, providing background on the Bristol Bay watershed ecosystem and the selection of policy strategy used by the Save Bristol Bay coalition. This study evaluates the Save Bristol Bay coalition using Smith's (2009) framework for successful coalition collaboration to better reflect natural-resource conflicts when coalitions disagree and are not able to find common ground. The results of the analysis conclude that under adversarial policy subsystems, the Save Bristol Bay coalition uses uncertainty founded in science to educate and motivate the public through precipitating events, while macropolitical actors use the conflict as a wedge issue to gain public support. Raising uncertainty to macropolitical actors is essential to move the policy from the public agenda to the formal agenda and ultimately produce the desired policy outcome by the Save Bristol Bay coalition.

Download or read book An Assessment of Potential Mining Impacts on Salmon Ecosystems of Bristol Bay, Alaska Volume 1 - Main Report written by U S Environmental Protection Agency and published by CreateSpace. This book was released on 2014-08-02 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report evaluates the potential impacts of large-scale mining development on salmon and other fish populations, wildlife, and Alaska Native cultures in the Nushagak River and Kvichak River watersheds of Bristol Bay, Alaska. It is not an assessment of a specific mine proposal for development, nor does it outline decisions made or to be made by the U.S. Environmental Protection Agency (USEPA). The assessment was conducted as an ecological risk assessment and starts with a review and characterization of the fisheries, wildlife, and Alaska Native cultures of the Bristol Bay watershed, particularly the Nushagak and Kvichak River watersheds. We developed realistic mine scenarios that include an open pit mine producing 0.25, 2.0, and 6.5 billion tons of ore and a 138-km transportation corridor. Based on these mine scenarios, we conclude that mining would, at minimum, cause the loss of spawning and rearing habitat for multiple salmonids (Pacific salmon, rainbow trout, and Dolly Varden). The mine footprint in each of the three scenarios would likely result in the direct loss of 38, 90, and 145 km of streams and 5.0, 12.4 and 19.4 km2 of wetlands, respectively. Water withdrawals for mine operations would significantly diminish habitat quality in an additional 15, 26 and 54 km of streams. Leakage of tailings and waste rock leachates during routine operations would result in instream copper levels sufficient to cause direct effects on salmonids in 29 and 57 km of streams beyond the mine footprint in the 2.0- and 6.5-billion-ton scenarios unless additional mitigation measures were taken. These leakages would not be likely to cause direct effects in streams under the 0.25-billion-ton scenario. Under a reasonable upper bound failure scenario for the wastewater treatment plant, copper concentrations would be sufficient to cause direct effects on salmonid fish in 45, 100, and 100 km of streams, respectively, under each mine scenario. The transportation corridor would cross 53 streams and rivers known or likely to support migrating and/or resident salmonids. At those road crossings, culvert failures could inhibit fish migration and degrade habitat, truck accidents could spill industrial chemicals, and runoff could reduce water quality. Failure of a tailings dam has a very low probability of occurrence, but a spill of 20% of the tailings from a single tailings storage facility would destroy more than 30 stream km, and more streams and rivers would have greatly degraded habitat for decades. A spill of product concentrate slurry along the transportation corridor would result in toxicity to fish in streams between the road and Iliamna Lake. Reductions in the populations of salmon would be expected from these habitat losses and toxic effects, but cannot be quantified. These losses would adversely affect the Alaska Native cultures and the wildlife of the region. The Nushagak River and Kvichak River watersheds contain multiple sites under consideration for large-scale mining. Potential risks of mining development on salmon and other fish populations are likely to increase as a result of the cumulative impacts of multiple mines.

Download or read book Coastal and Deep Ocean Pollution written by Andres Hugo Arias and published by CRC Press. This book was released on 2020-03-10 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.

Book Synopsis The Bears of Brooks Falls: Wildlife and Survival on Alaska's Brooks River by : Michael Fitz
Download or read book The Bears of Brooks Falls: Wildlife and Survival on Alaska's Brooks River written by Michael Fitz and published by The Countryman Press. This book was released on 2021-03-09 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: A natural history and celebration of the famous bears and salmon of Brooks River. On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America’s greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them (with as many as forty-three bears sighted in a single day), and thousands of people come to watch in person or on the National Park Service’s popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous in three parts. The first forms an ecological history of the region, from its dormancy 30,000 years ago to the volcanic events that transformed it into the Valley of Ten Thousand Smokes. The central and longest section is a deep dive into the lives of the wildlife along the Brooks River, especially the bears and salmon. Readers will learn about the bears’ winter hibernation, mating season, hunting rituals, migration patterns, and their relationship with Alaska’s changing environment. Finally, the book explores the human impact, both positive and negative, on this special region and its wild population.
