Approaches For Ecosystem Services Valuation For The Gulf Of Mexico After The Deepwater Horizon Oil Spill

On April 20, 2010, the Deepwater Horizon platform drilling the Macondo well in Mississippi Canyon Block 252 (DWH) exploded, killing 11 workers and injuring another 17. The DWH oil spill resulted in nearly 5 million barrels (approximately 200 million gallons) of crude oil spilling into the Gulf of Mexico (GoM). The full impacts of the spill on the GoM and the people who live and work there are unknown but expected to be considerable, and will be expressed over years to decades. In the short term, up to 80,000 square miles of the U.S. Exclusive Economic Zone (EEZ) were closed to fishing, resulting in loss of food, jobs and recreation. The DWH oil spill immediately triggered a process under the U.S. Oil Pollution Act of 1990 (OPA) to determine the extent and severity of the "injury" (defined as an observable or measurable adverse change in a natural resource or impairment of a natural resource service) to the public trust, known as the Natural Resources Damage Assessment (NRDA). The assessment, undertaken by the trustees (designated technical experts who act on behalf of the public and who are tasked with assessing the nature and extent of site-related contamination and impacts), requires: (1) quantifying the extent of damage; (2) developing, implementing, and monitoring restoration plans; and (3) seeking compensation for the costs of assessment and restoration from those deemed responsible for the injury. This interim report provides options for expanding the current effort to include the analysis of ecosystem services to help address the unprecedented scale of this spill in U.S. waters and the challenges it presents to those charged with undertaking the damage assessment.

As the Gulf of Mexico recovers from the Deepwater Horizon oil spill, natural resource managers face the challenge of understanding the impacts of the spill and setting priorities for restoration work. The full value of losses resulting from the spill cannot be captured, however, without consideration of changes in ecosystem services-the benefits delivered to society through natural processes. An Ecosystem Services Approach to Assessing the Impacts of the Deepwater Horizon Oil Spill in the Gulf of Mexico discusses the benefits and challenges associated with using an ecosystem services approach to damage assessment, describing potential impacts of response technologies, exploring the role of resilience, and offering suggestions for areas of future research. This report illustrates how this approach might be applied to coastal wetlands, fisheries, marine mammals, and the deep sea-each of which provide key ecosystem services in the Gulf-and identifies substantial differences among these case studies. The report also discusses the suite of technologies used in the spill response, including burning, skimming, and chemical dispersants, and their possible long-term impacts on ecosystem services.

Gulf Coast communities and natural resources suffered extensive direct and indirect damage as a result of the largest accidental oil spill in US history, referred to as the Deepwater Horizon (DWH) oil spill. Notably, natural resources affected by this major spill include wetlands, coastal beaches and barrier islands, coastal and marine wildlife, seagrass beds, oyster reefs, commercial fisheries, deep benthos, and coral reefs, among other habitats and species. Losses include an estimated 20% reduction in commercial fishery landings across the Gulf of Mexico and damage to as much as 1,100 linear miles of coastal salt marsh wetlands. This historic spill is being followed by a restoration effort unparalleled in complexity and magnitude in U.S. history. Legal settlements in the wake of DWH led to the establishment of a set of programs tasked with administering and supporting DWH-related restoration in the Gulf of Mexico. In order to ensure that restoration goals are met and money is well spent, restoration monitoring and evaluation should be an integral part of those programs. However, evaluations of past restoration efforts have shown that monitoring is often inadequate or even absent. Effective Monitoring to Evaluate Ecological Restoration in the Gulf of Mexico identifies best practices for monitoring and evaluating restoration activities to improve the performance of restoration programs and increase the effectiveness and longevity of restoration projects. This report provides general guidance for restoration monitoring, assessment, and synthesis that can be applied to most ecological restoration supported by these major programs given their similarities in restoration goals. It also offers specific guidance for a subset of habitats and taxa to be restored in the Gulf including oyster reefs, tidal wetlands, and seagrass habitats, as well as a variety of birds, sea turtles, and marine mammals.

Interrelationships Between Corals and Fisheries is derived from a workshop held by the Gulf of Mexico Fishery Management Council in Tampa, Florida in May 2013, where world authorities came together to discuss the current problems in managing tropical fisheries and offered suggestions for future directions for both researchers and environmental reso

This book is an essential contribution to understanding Russian law for English speakers. In a time when the energy markets in Europe are changing away from Russian dependence on oil and gas, Dr Svendsen explains what the legal consequences will be if we would experience cross-border harm as a result of an oil spill from offshore installations on the Norwegian and the Russian side of the sea border in the Barents Sea. This book examines Russian and Norwegian rules governing liability, choice-of-law, recognition and enforcement, damage, third-party losses, environmental harm, and valuation of environmental harm.

Contextualizes and analyzes the key energy transitions in U.S. history and the central importance of energy production and consumption on the American environment and in American culture and politics. Focusing on the major energy transitions in U.S. history, from the pre-industrial era to the present day, this two-volume encyclopedia captures the major advancements, events, technologies, and people synonymous with the production and consumption of energy in the United States. Expert contributors show how, for example, the introduction of electricity and petroleum into ordinary American life facilitated periods of rapid social and political change, as well as profound and ongoing impacts on the environment. These developments have in many ways defined and accelerated the pace of modern life and led to vast improvements in living conditions for millions of people, just as they have also brought new fears of resource exhaustion and fossil-fuel induced climate change. Today, as America begins to move beyond the use of fossil fuels toward a greater reliance on renewables, including wind and solar energy, there is a pressing need to understand energy in America's past in order to better understand its energy future.

The lack of international conventional law governing the operational aspects of continental shelf activity may be characterized as unfinished business of the UN Convention on the Law of the Sea. The Convention, adopted in 1982, generally addressed the issue but did not consider more detailed development of the legal regime for the continental shelf. In The Regulation of Continental Shelf Development: Rethinking International Standards, leading experts from around the world identify and explore a multitude of unresolved legal concerns related to the continental shelf. The current state of continental shelf activities is explored through the following lenses: • Contemporary uses, including an overview on offshore wind energy in the EU, an analysis of the use of submarine cables under UNCLOS, and a discussion of the varied potential for mining marine materials; • Emerging challenges, such as ISA seabed mining standards, the recent ITLOS decision regarding the Bay of Bengal, and the role of the IMO in establishing safety standards for transboundary effects of oil pollution for offshore platforms; • Comparative best practices in environmental regulation; • Probabilistic risk assessment, with a thorough definition of PRA and a critical examination of continental shelf disasters; • Decommissioning offshore installations and structures, including an overview of the global regime as particularly provided in Articles 60(3) and 80 of UNCLOS; • Liability and compensation; and finally, • Unfinished business on UNCLOS III. The varied voices of experts collected within The Regulation of Continental Shelf Development: Rethinking International Standards offer a timely understanding of past, present, and future issues related to the continental shelf. The volume is a must-read for all those interested in environmental law and the law of the sea.

The ecosystem services (ES) framework opens the door to common ground between ecology science and economics in facing the challenge of planetary sustainability. Application of the available methodologies and instruments reveals both the high potential and the controversies related to this new socio-ecological management approach. Feeding on the research, reviews and testimonies presented at the XV International Summer School on Environment (ISSE) of the University of Girona (2015), this proceedings book displays the main concepts related the ES approach and outcomes from case studies dealing with its operationalization. However, the ultimate goal of this crosswalk language remains; changing mentalities and raising awareness to the point of installing new socio-ecological values, leading society to economic models in which ES conservation is understood as subsistence premise and therefore an intrinsic component of profits.
