In the race to feed the world’s seven billion people, we are at a standstill. Over the past century, we have developed increasingly potent and sophisticated pesticides, yet in 2014, the average percentage of U.S. crops lost to agricultural pests was no less than in 1944. To use a metaphor the field of evolutionary biology borrowed from Alice in Wonderland, farmers must run ever faster to stay in the same place—i.e., produce the same yields. With Chasing the Red Queen, Andy Dyer offers the first book to apply the Red Queen Hypothesis to agriculture. Dyer examines one of the world’s most pressing problems as a biological case study. He presents key concepts, from Darwin’s principles of natural selection to genetic variation and adaptive phenotypes. Understanding the fundamentals of ecology and biology is the first step to “playing the Red Queen,” and escaping her unwinnable race. The book’s novel frame will help students, researchers, and policy-makers alike apply that knowledge to the critical task of achieving food security.

This book presents valuable insights on a vast array of topics in the field of environmental studies. The works published in the book were presented within the scope of the 2013 Sopot Forum of Young Scientists. The Forum is an annual event which provides a platform for young researchers to present their work and exchange ideas with their peers. The aim of the forum is to make science more popular, so the speakers talked about their work in a way that was easily understandable. The book contains actual scientific papers on their own topics of interest. The papers represent different areas of environmental sciences, from biology to physics. The main umbrella topic for this book is "WHERE THE WORLD IS HEADING" and the papers are constructed in such a way as to try to answer this from each contributor's individual perspective.

Remediation of chlorinated solvent source zones is very difficult, at times controversial, and must be based on state-of-the-art knowledge of the behavior of nonaqueous phase liquids in the subsurface, as well as site specific geology, chemistry, biology and hydrogeology.  This volume begins with an overview of the current state-of-the-practice that serves as an introduction to the rest of the book. The second chapter summarizes the challenges involved in source zone remediation, which has been and remains contentious, expensive and difficult, for a variety of reasons. Following are chapters providing more focused discussions of specific aspects of this overall challenge: ·         Two chapters on source zone characterization, the first summarizing the current issues and techniques, and the second focusing on several innovative diagnostic methods. ·         Two chapters on modeling, the first focused on modeling source zone remediation itself, and the second focused on the responses of downgradient plumes to source remediation. ·         A chapter on the use of mass flux and mass discharge information to improve source zone management and remediation.   ·         A series of chapters on specific source zone remediation methods, including hydraulic displacement and recovery, in situ chemical oxidation (ISCO), in situ chemical reduction (ISCR), enhanced flushing with cosolvents and surfactants, in situ bioremediation, and finally source zone monitored natural attenuation. ·         A chapter on combined remedies, discussing the fundamental issues involved in developing effective combined remedies. ·         A chapter on the costs of source zone treatment, using several hypothetical site scenarios, comparing different technologies on a total and net present cost basis. The last two chapters consider the future of source zone remediation, beginning with a discussion of alternate management strategies, followed by a summary of the research and development needed to improve the state of the practice.  Each chapter in this volume has been reviewed for technical content by two or more experts in each subject area covered. This volume will provide a useful reference for practitioners, researchers and students involved in remediation of chlorinated solvent source zones.

Citizens expect their governments to lead on sustainability. But from largely disappointing international conferences like Rio II to the U.S.’s failure to pass meaningful climate legislation, governments’ progress has been lackluster. That’s not to say leadership is absent; it just often comes from the bottom up rather than the top down. Action—on climate, species loss, inequity, and other sustainability crises—is being driven by local, people’s, women’s, and grassroots movements around the world, often in opposition to the agendas pursued by governments and big corporations. These diverse efforts are the subject of the latest volume in the Worldwatch Institute’s highly regarded State of the World series. The 2014 edition, marking the Institute’s 40th anniversary, examines both barriers to responsible political and economic governance as well as gridlock-shattering new ideas. The authors analyze a variety of trends and proposals, including regional and local climate initiatives, the rise of benefit corporations and worker-owned firms, the need for energy democracy, the Internet’s impact on sustainability, and the importance of eco-literacy. A consistent thread throughout the book is that informed and engaged citizens are key to better governance. The book is a clear-eyed yet ultimately optimistic assessment of citizens’ ability to govern for sustainability. By highlighting both obstacles and opportunities, State of the World 2014 shows how to effect change within and beyond the halls of government. This volume will be especially useful for policymakers, environmental nonprofits, students of environmental studies, sustainability, or economics—and citizens looking to jumpstart significant change around the world.
