Geoecological and Geopolitical Risks for the Oil and Gas Industry in the Arctic: Challenges and threats (Environmental Pollution #29)

by Vladimir N. Bashkin Olga Р. Trubitsina

This book discusses issues of geoecological (GER) and geopolitical (GPR) risks due to hydrocarbon development of the Arctic. The authors explain the ethical and philosophical foundations of understanding environmental equity and justice in relation to the development of Arctic natural resources and consider various approaches to the moral aspects of making global management decisions in the field of environmental protection and environmental safety. Special attention is paid to analysis of modern geopolitical and geostrategic challenges to the development of the Arctic region. The monograph identifies the key geopolitical factors affecting the sustainable development of the Arctic and analyzes the similarities and differences in the geostrategic positions of the five Arctic states. The authors reveal the need to consider geopolitical challenges in the process of GER analysis for oil and gas development in the Arctic region. The book explores the intersection of the strategic interests for a number of states and describes Russia's inability to ensure environmental safety in the development of Arctic deposits. The book analyzes in detail each type of GER with an emphasis on their potential to lead to additional opportunities and threats, and assesses environmental rating as an indicator of the GER management process of Russian oil and gas companies operating in the Arctic. Although the main focus is on the Russian part of this region, many arguments and conclusions are quite applicable to the entire Arctic region. The consideration of geoecological and geopolitical aspects of the development of Arctic resources with the example of Russian oil and gas companies sheds light on the entire Arctic region, taking into account the interests of all other national and international companies involved in GER and GPR there.

Following background coverage of geothermal resources and utilization in several countries, the basics of continuum mechanics for heat transport processes, as well as numerical methods for solving underlying governing equations are discussed. This examination forms the theoretical basis for five included step-by-step OpenGeoSys exercises, highlighting the most important computational areas within geothermal resource utilization, including heat diffusion, heat advection in porous and fractured media, and heat convection. The book concludes with an outlook on practical follow-up contributions investigating the numerical simulation of shallow and deep geothermal systems.

Geoenergy Modeling II

by Olaf Kolditz Agnes Sachse Haibing Shao Philipp Hein

This book is dedicated to the numerical modeling of shallow geothermal systems. The utilization of shallow geothermal energy involves the integration of multiple Borehole Heat Exchangers (BHE) with Ground Source Heat Pump (GSHP) systems to provide heating and cooling. The modeling practices explained in this book can improve the efficiency of these increasingly common systems. The book begins by explaining the basic theory of heat transport processes in man-made as well as natural media. . These techniques are then applied to the simulation of borehole heat exchangers and their interaction with the surrounding soil. The numerical and analytical models are verified against analytical solutions and measured data from a Thermal Response Test, and finally, a real test site is analyzed through the model and discussed with regard to BHE and GSHP system design and optimization.

In order to help readers gain a system-level understanding of the necessary analysis, the authors include detailed examples of growing complexity as the techniques explained in the text are introduced. The coverage culminates with the fully-coupled analysis of real deep geothermal test-sites located in Germany and France.

Geoengineering our Climate?: Ethics, Politics, and Governance (The Earthscan Science in Society Series)

by Jason J. Blackstock Sean Low

If the detrimental impacts of human-induced climate change continue to mount, technologies for geoengineering our climate – i.e. deliberate modifying of the Earth's climate system at a large scale – are likely to receive ever greater attention from countries and societies worldwide. Geoengineering technologies could have profound ramifications for our societies, and yet agreeing on an international governance framework in which even serious research into these planetary-altering technologies can take place presents an immense international political challenge. In this important book, a diverse collection of internationally respected scientists, philosophers, legal scholars, policymakers, and civil society representatives examine and reflect upon the global geoengineering debate they have helped shape. Opening with essays examining the historic origins of contemporary geoengineering ideas, the book goes on to explore varying perspectives from across the first decade of this global discourse since 2006. These essays methodically cover: the practical and ethical dilemmas geoengineering poses; the evolving geoengineering research agenda; the challenges geoengineering technologies present to current international legal and political frameworks; and differing perceptions of geoengineering from around the world. The book concludes with a series of forward looking essays, some drawing lessons from precedents for governing other global issues, others proposing how geoengineering technologies might be governed if/as they begin to emerge from the lab into the real world. This book is an indispensable resource for scientists, activists, policymakers, and political figures aiming to engage in the emerging debate about geoengineering our climate.

Geoengineering: The Gamble

by Gernot Wagner

Stabilizing the world’s climates means cutting carbon dioxide pollution. There’s no way around it. But what if that’s not enough? What if it’s too difficult to accomplish in the time allotted or, worse, what if it’s so late in the game that even cutting carbon emissions to zero, tomorrow, wouldn’t do? Enter solar geoengineering. The principle is simple: attempt to cool Earth by reflecting more sunlight back into space. The primary mechanism, shooting particles into the upper atmosphere, implies more pollution, not less. If that doesn’t sound scary, it should. There are lots of risks, unknowns, and unknowables. In Geoengineering: The Gamble, climate economist Gernot Wagner provides a balanced take on the possible benefits and all-too-real risks, especially the so-called “moral hazard” that researching or even just discussing (solar) geoengineering would undermine the push to cut carbon emissions in the first place. Despite those risks, he argues, solar geoengineering may only be a matter of time. Not if, but when. As the founding executive director of Harvard’s Solar Geoengineering Research Program, Wagner explores scenarios of a geoengineered future, offering an inside-view of the research already under way and the actions the world must take to guide it in a productive direction.

Geoenvironmental Practices and Sustainability

by G. L. Sivakumar Babu Krishna R. Reddy Anirban De Manoj Datta

This volume is a compilation on issues related to sustainable practices in geo-environmental engineering, particularly as applying to developing nations such as India. While, the developed world has already developed some solutions such as landfills, developments in landfills, barriers and liners in the North America and waste-to-energy and waste incineration in Europe, developing countries like India are trying to figure out ways which suit the present condition without compromising the future needs and comforts. This volume presents case studies on the various problems and solutions adopted for different sites. Although a common approach for all the problems is not feasible or recommend, this collection aims to provide a compendium on the current efforts underway and to help achieve common ground for the practitioners and researchers involved. The works included here give insight to the possible development of resilient and sustainable structures (like offshore wind turbines) and energy geotechnics. The book covers topics such as liners and barrier systems, use of recycled and waste materials, waste management and hazard assessment, sustainable infrastructure, and sustainability and the environment. The contents of this book will be useful to researchers and professionals working in geo-environmental engineering. The book will also be useful to policy makers interested in understanding geotechnical concerns related to sustainable development.

Geofuels

by Alan R. Carroll

Our energy use and its consequences (including climate change) motivate some of the most contentious and complex public debates of our time. Although these issues are often cast in terms of renewable versus non-renewable energy, in reality both depend on finite Earth resources. The evolution of the Earth itself therefore offers a uniquely illuminating perspective from which to evaluate alternative pathways toward energy and environmental sustainability. Geofuels: Energy and the Earth systematically develops this perspective using informal, nontechnical language laced with humor. It is well suited to a broad readership, ranging from beginning university students to lifelong learners who are interested in how the Earth's past will influence their own future. It also provides simplified explanations of controversial topics, such as energy return on energy investment, peak oil, and fracking. The focus throughout is on building a sound physical understanding of how natural resources constrain our use of energy.

Geographic Information Research: Bridging The Atlantic

by Massimo Craglia; Helen Couclelis

The contributors to this edited collection demonstrate that geographic information research is truly global in character, cutting across a wide range of disciplines and addressing conceptual, methodological, technical, ethical and political issues alike. Of the six themes, two are broadly concerned with data integration (geographic data infrastructures, GIS diffusion and implementation); two are more technical and conceptual in nature (generalisation, concepts and paradigms), and two reflect to a larger extent the application-driven nature of GIS technology (spatial analysis and multimedia). Each section is introduced by chapters highlighting the key research issues. Further chapters explore these issues in greater depth, and benefit from the international collaboration. Through the comparison of results included in this book, the prospects for advancing the field and addressing the challenges of GIS research are greatly improved.
