How do we explain the remarkably abrupt changes that sometimes occur in nature and society--and can we predict why and when they happen? This book offers a comprehensive introduction to critical transitions in complex systems--the radical changes that happen at tipping points when thresholds are passed. Marten Scheffer accessibly describes the dynamical systems theory behind critical transitions, covering catastrophe theory, bifurcations, chaos, and more. He gives examples of critical transitions in lakes, oceans, terrestrial ecosystems, climate, evolution, and human societies. And he demonstrates how to deal with these transitions, offering practical guidance on how to predict tipping points, how to prevent "bad" transitions, and how to promote critical transitions that work for us and not against us. Scheffer shows the time is ripe for understanding and managing critical transitions in the vast and complex systems in which we live. This book can also serve as a textbook and includes a detailed appendix with equations. Provides an accessible introduction to dynamical systems theory Covers critical transitions in lakes, oceans, terrestrial ecosystems, the climate, evolution, and human societies Explains how to predict tipping points Offers strategies for preventing "bad" transitions and triggering "good" ones Features an appendix with equations

Phase transitions--changes between different states of organization in a complex system--have long helped to explain physics concepts, such as why water freezes into a solid or boils to become a gas. How might phase transitions shed light on important problems in biological and ecological complex systems? Exploring the origins and implications of sudden changes in nature and society, Phase Transitions examines different dynamical behaviors in a broad range of complex systems. Using a compelling set of examples, from gene networks and ant colonies to human language and the degradation of diverse ecosystems, the book illustrates the power of simple models to reveal how phase transitions occur. Introductory chapters provide the critical concepts and the simplest mathematical techniques required to study phase transitions. In a series of example-driven chapters, Ricard Solé shows how such concepts and techniques can be applied to the analysis and prediction of complex system behavior, including the origins of life, viral replication, epidemics, language evolution, and the emergence and breakdown of societies. Written at an undergraduate mathematical level, this book provides the essential theoretical tools and foundations required to develop basic models to explain collective phase transitions for a wide variety of ecosystems.

As scientific understanding about ecological processes has grown, the idea that ecosystem dynamics are complex, nonlinear, and often unpredictable has gained prominence. Of particular importance is the idea that rather than following an inevitable progression toward an ultimate endpoint, some ecosystems may occur in a number of states depending on past and present ecological conditions. The emerging idea of “restoration thresholds” also enables scientists to recognize when ecological systems are likely to recover on their own and when active restoration efforts are needed. Conceptual models based on alternative stable states and restoration thresholds can help inform restoration efforts. New Models for Ecosystem Dynamics and Restoration brings together leading experts from around the world to explore how conceptual models of ecosystem dynamics can be applied to the recovery of degraded systems and how recent advances in our understanding of ecosystem and landscape dynamics can be translated into conceptual and practical frameworks for restoration. In the first part of the book, background chapters present and discuss the basic concepts and models and explore the implications of new scientific research on restoration practice. The second part considers the dynamics and restoration of different ecosystems, ranging from arid lands to grasslands, woodlands, and savannahs, to forests and wetlands, to production landscapes. A summary chapter by the editors discusses the implications of theory and practice of the ideas described in preceding chapters. New Models for Ecosystem Dynamics and Restoration aims to widen the scope and increase the application of threshold models by critiquing their application in a wide range of ecosystem types. It will also help scientists and restorationists correctly diagnose ecosystem damage, identify restoration thresholds, and develop corrective methodologies that can overcome such thresholds.

A comprehensive account of how energy has shaped society throughout history, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. "I wait for new Smil books the way some people wait for the next 'Star Wars' movie. In his latest book, Energy and Civilization: A History, he goes deep and broad to explain how innovations in humans' ability to turn energy into heat, light, and motion have been a driving force behind our cultural and economic progress over the past 10,000 years. —Bill Gates, Gates Notes, Best Books of the Year Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows—ranging from fossil fuels to photovoltaic generation of electricity—for their civilized existence. In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. Humans are the only species that can systematically harness energies outside their bodies, using the power of their intellect and an enormous variety of artifacts—from the simplest tools to internal combustion engines and nuclear reactors. The epochal transition to fossil fuels affected everything: agriculture, industry, transportation, weapons, communication, economics, urbanization, quality of life, politics, and the environment. Smil describes humanity's energy eras in panoramic and interdisciplinary fashion, offering readers a magisterial overview. This book is an extensively updated and expanded version of Smil's Energy in World History (1994). Smil has incorporated an enormous amount of new material, reflecting the dramatic developments in energy studies over the last two decades and his own research over that time.

This book offers a critical analysis of core concepts that have influenced contemporary conversations about environment-society relations in academic, political, and civil circles. Considering these conceptualizations are currently shaping responses to environmental crises in fundamental ways, critical reflections on concepts such as the Anthropocene, metabolism, risk, resilience, environmental governance, environmental justice and others, are well-warranted. Contributors to this volume, working across a multitude of areas within environmental social science, scrutinize underlying worldviews and assumptions, asking a common set of key questions: What are the different concepts able to explain? How do they take into account society-environment relations? What social, cultural, or geo-political biases and blinders are inherent? What actions or practices do the concepts inspire? The transdisciplinary engagement and reflexivity regarding concepts of environment-society relations represented in these chapters is needed in all spheres of society—in academia, policy and practice—not the least to confront current tendencies of anti-reflexivity and denialism.

We all know that our planet is losing its biological diversity at an alarming rate, with frightening implications for our future. But when does an ecosystem hit the breaking point? In this important book, Princeton biologist Simon Levin offers general readers the first look at how the new science of complexity can help to solve our looming ecological crisis. Levin argues that our biosphere is the classic embodiment of what scientists call complex adaptive systems. By exploring how such systems work, we can determine how they might fail: How much loss can an ecosystem bear before it starts to collapse? How resilient are these systems? Do they in fact hover at the edge of chaos? A deeply original work on one of the most pressing issues of our time, Fragile Dominion is a powerful appeal to understand and protect the global “commons.”

This book evaluates the relevance of classical debates on agrarian transition and extends the horizon of contemporary debates in the Indian context, linking national trends with regional experiences. It identifies new dynamics in agrarian political economy and presents a comprehensive account of diverse aspects of capitalist transition both at theoretical and empirical levels. The essays discuss several neglected domains in agricultural economics such as discursive dimensions of agrarian relations and limitations of stereotypical binaries between capital and non-capital, rural and urban sectors, agriculture and industry, and accumulation and subsistence. With contributions from major scholars in the field, this volume will be useful to scholars and researchers of agriculture, economics, political economy, sociology, rural development and development studies.

"The book presents a novel strategy for addressing the major environmental and social problems of our time. It emphasizes transformative actions by individual citizens, both ordinary and extraordinary, rather than by government and other groups. It empowers a spectrum of solutions appropriate to people with varying interests, skills, political persuasions, and level of environmental and social commitment. The book draws on social and ecological theory to formulate a four-tiered stewardship strategy to transform our communities, nations, and planet. Key elements of this strategy are (1) individual actions that link people with nature and reduce human impacts on the planet, (2) effective communication to reduce political polarization and share solutions, (3) collaborations that integrate actions of multiple groups, and (4) political engagement to trigger needed transformations. The book builds on diverse visions and goals for the future of ecosystems and society: concern for the future of our children and grandchildren, a spiritual commitment to care for Creation and vulnerable people, a desire to sustain the best of nature and of cultures, and a concern about the security and well-being of our communities, nations, and the world. This is not a book about what should be done. It is a book about what has been and can be done and a pragmatic strategy for tangible progress"--
