Over the course of its 150-year history, California has successfully protected its scenic wilderness areas, restricted coastal oil drilling, regulated automobile emissions, preserved coastal access, improved energy efficiency, and, most recently, addressed global climate change. How has this state, more than any other, enacted so many innovative and stringent environmental regulations over such a long period of time? This book shows why the Golden State has been at the forefront in setting new environmental standards, often leading the rest of the nation. From the establishment of Yosemite, America's first protected wilderness, and the prohibition of dumping gold-mining debris in the nineteenth century to sweeping climate-change legislation in the twenty-first, the book traces California's remarkable environmental policy trajectory. It explains that this pathbreaking role developed because California had more to lose from environmental deterioration and more to gain from preserving its stunning natural geography. As a result, citizens and civic groups effectively mobilized to protect and restore their state's natural beauty and, importantly, were often backed both by business interests and by strong regulatory authorities. Business support for environmental regulation in California reveals that strict standards are not only compatible with economic growth but can also contribute to it. The book also examines areas where California has fallen short, particularly in water management and the state's dependence on automobile transportation.

Individual Vulnerability

Parting from conventional social science arguments that people speak for the ethnic groups they represent or for social or class-based groups, this study argues that attitudes of Ecuador’s Amazon citizens are shaped by environmental vulnerability, and specifically exposure to environmental degradation. Using results of a nationwide survey to demonstrate that vulnerability matters in determining environmental attitudes of respondents, the authors argue that groups might have more success mobilizing on behalf of the environment through geographically based “polycentric rights,” rather than through more traditional and ethnically bound multicultural rights. This book offers among the first methodological bridges between scholarship considering social movements, and predominantly ethnic groups, as primary agents of environmental change in Latin America and those emphasizing the agency of individuals. The authors conduct a nationwide survey to glean respondent positions on a range of environmental issues, then contextualize these findings through scores of in-depth interviews with indigenous, environmental, government, academic, and civil society leaders throughout Ecuador between 2014 and 2017. They find that some abstract issues—like indigenous worldviews—affect peoples’ attitudes, but that concrete experiences—such as that of living in areas of environmental degradation due to oil drilling—is a more important conditioner of environmental attitudes. The authors qualify post-materialism, an early theory of environmentalism, which argues that material well-being makes citizens more protective of the environment. The book concludes that post-materialism must be tempered by individual vulnerability, and that group activism is more successful where people have not yet been adversely impacted by environmental degradation such as oil spills and forest destruction.

Shallow Seas

Oil drilling and extraction platforms are currently being used in many offshore areas around the world. Whilst those operating in shallow seas are secured to the seabed, for deeper water operations, Dynamic Positioning (DP) is essential for the platforms to maintain their position within a safe zone. Operating DP requires intelligent and reliable control systems. Nearly all DP accidents have been caused by a combination of technical and human failures; however, according to the International Marine Contractors Association (IMCA) DP Incidents Analysis, DP control and thruster system failures have been the leading causes of incidents over the last ten years. This paper will investigate potential operational improvements for DP system accuracy by adding a Predictive Neural Network (PNN) control algorithm in the thruster allocation along with a nonlinear Proportional Integral derivative (PID) motion control system. A DP system’s performance on a drilling platform in oil and gas deep-water fields and subject to real weather conditions is simulated with these advanced control methods. The techniques are developed for enhancing the safety and reliability of DP operations to improve the positioning accuracy, which may allow faster response to a critical situation during DP drilling operations. The semisubmersible drilling platform’s simulation results using the PNN strategy show improved control of the platform’s positioning.
