Arid and Semi-Arid Landscapes (ASALs) support millions of people worldwide yet these livelihoods and landscapes are increasingly vulnerable in the face of multiple environmental stressors. In recent decades, climate change and variability of rainfall -- from droughts to increasingly patchy rainfall - have exacerbated this vulnerability and worsened aridity in many ASALs. Climate change is also expected to cause shifts in climate suitability of crops and increase the suitability of some crop disease vectors, pests, and diseases, potentially leading to further decrease in productivity of crops and pastoral systems. Increasing demand for row crop agriculture has further caused unsustainable intensification and expansion of cropland into ASALs and forests leading to continuous degradation of the ecological landscape. Such dynamics collectively change the structure and function of ASALs in unknown ways that reduce social-ecological system (SES) resilience. Recent expansion of cropland into arid and semi-arid land and forests further threatens traditional livelihoods and ecosystem services. Successful mainstreaming of climate change adaptation policies requires integrative approaches that span the socioeconomic and biophysical spheres, especially within complex social-ecological systems. Limited studies have been done to characterize dynamics of agropastoral landscapes in the sub-Saharan region where vulnerability to climate change is highest, and where local assessment of impact is necessary to adequately determine adaptation strategies. My dissertation research investigated landscape dynamics of the agropastoral landscape of Narok, Kenya -- as a case study site, focusing on the nature and impacts of climate induced changes in rainfall patterns, and historical legacies of land policies to understand how the resultant landscape supports ecosystem services abundance and access to address local vulnerability. To begin with, in Chapter 2, I investigated the influence of historical land policies on contemporary patterns of land use and land cover to determine potential impacts on ecosystem services. In Chapter 3, I characterized the spatial and temporal patterns of rainfall variability. In Chapter 4, I explored local perceptions of change in rainfall patterns, and its impacts. Collectively, my dissertation generated essential knowledge on dynamics of a complex and vulnerable agropastoral landscape that are necessary for determining contextualized adaptation strategies and enhancing social-ecological resilience.

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.”

Increasingly, cracks are appearing in the capacity of communities, ecosystems, and landscapes to provide the goods and services that sustain our planet's well-being. The response from most quarters has been for "more of the same" that created the situation in the first place: more control, more intensification, and greater efficiency. "Resilience thinking" offers a different way of understanding the world and a new approach to managing resources. It embraces human and natural systems as complex entities continually adapting through cycles of change, and seeks to understand the qualities of a system that must be maintained or enhanced in order to achieve sustainability. It explains why greater efficiency by itself cannot solve resource problems and offers a constructive alternative that opens up options rather than closing them down. In Resilience Thinking, scientist Brian Walker and science writer David Salt present an accessible introduction to the emerging paradigm of resilience. The book arose out of appeals from colleagues in science and industry for a plainly written account of what resilience is all about and how a resilience approach differs from current practices. Rather than complicated theory, the book offers a conceptual overview along with five case studies of resilience thinking in the real world. It is an engaging and important work for anyone interested in managing risk in a complex world.

Reflecting the very latest research, this book provides an in-depth review of the role of resilience in the management of social-ecological systems and the ecosystem services they provide. Leaders in the field outline seven principles for building resilience in social-ecological systems, examining how these can be applied to advance sustainability.

It is usually the case that scientists examine either ecological systems or social systems, yet the need for an interdisciplinary approach to the problems of environmental management and sustainable development is becoming increasingly obvious. Developed under the auspices of the Beijer Institute in Stockholm, this new book analyses social and ecological linkages in selected ecosystems using an international and interdisciplinary case study approach. The chapters provide detailed information on a variety of management practices for dealing with environmental change. Taken as a whole, the book will contribute to the greater understanding of essential social responses to changes in ecosystems, including the generation, accumulation and transmission of ecological knowledge, structure and dynamics of institutions, and the cultural values underlying these responses. A set of new (or rediscovered) principles for sustainable ecosystem management is also presented. Linking Social and Ecological Systems will be of value to natural and social scientists interested in sustainability.

This open access book brings together research findings and experiences from science, policy and practice to highlight and debate the importance of nature-based solutions to climate change adaptation in urban areas. Emphasis is given to the potential of nature-based approaches to create multiple-benefits for society. The expert contributions present recommendations for creating synergies between ongoing policy processes, scientific programmes and practical implementation of climate change and nature conservation measures in global urban areas.

This handbook addresses a growing list of challenges faced by regions and cities in the Pacific Rim, drawing connections around the what, why, and how questions that are fundamental to sustainable development policies and planning practices. These include the connection between cities and surrounding landscapes, across different boundaries and scales; the persistence of environmental and development inequities; and the growing impacts of global climate change, including how physical conditions and social implications are being anticipated and addressed. Building upon localized knowledge and contextualized experiences, this edited collection brings attention to place-based approaches across the Pacific Rim and makes an important contribution to the scholarly and practical understanding of sustainable urban development models that have mostly emerged out of the Western experiences. Nine sections, each grounded in research, dialogue, and collaboration with practical examples and analysis, focus on a theme or dimension that carries critical impacts on a holistic vision of city-landscape development, such as resilient communities, ecosystem services and biodiversity, energy, water, health, and planning and engagement. This international edited collection will appeal to academics and students engaged in research involving landscape architecture, architecture, planning, public policy, law, urban studies, geography, environmental science, and area studies. It also informs policy makers, professionals, and advocates of actionable knowledge and adoptable ideas by connecting those issues with the Sustainable Development Goals (SDGs) of the United Nations. The collection of writings presented in this book speaks to multiyear collaboration of scholars through the APRU Sustainable Cities and Landscapes (SCL) Program and its global network, facilitated by SCL Annual Conferences and involving more than 100 contributors from more than 30 institutions. The Open Access version of chapters 1, 2, 4, 11, 17, 23, 30, 37, 42, 49, and 56 of this book, available at http://www.taylorfrancis.com/books/e/9781003033530, have been made available under a Creative Commons Attribution-Non Commercial-No Derivatives 4.0 license.

This open access book presents up-to-date analyses of community-based approaches to sustainable resource management of SEPLS (socio-ecological production landscapes and seascapes) in areas where a harmonious relationship between the natural environment and the people who inhabit it is essential to ensure community and environmental well-being as well as to build resilience in the ecosystems that support this well-being. Understanding SEPLS and the forces of change that can weaken their resilience requires the integration of knowledge across a wide range of academic disciplines as well as from indigenous knowledge and experience. Moreover, given the wide variation in the socio-ecological makeup of SEPLS around the globe, as well as in their political and economic contexts, individual communities will be at the forefront of developing the measures appropriate for their unique circumstances. This in turn requires robust communication systems and broad participatory approaches. Sustainability science (SuS) research is highly integrated, participatory and solutions driven, and as such is well suited to the study of SEPLS. Through case studies, literature reviews and SuS analyses, the book explores various approaches to stakeholder participation, policy development and appropriate action for the future of SEPLS. It provides communities, researchers and decision-makers at various levels with new tools and strategies for exploring scenarios and creating future visions for sustainable societies.

This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

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.
