Book Description
The Changing Mile, originally published in 1965, was a benchmark in ecological studies, demonstrating the prevalence of change in a seemingly changeless place. Photographs made throughout the Sonoran Desert region in the late 1800s and early 1900s were juxtaposed with photographs of the same locations taken many decades later. The nearly one hundred pairs of images revealed that climate has played a strong role in initiating many changes in the region. This new book updates the classic by adding recent photographs to the original pairs, providing another three decades of data and showing even more clearly the extent of change across the landscape. During these same three decades, abundant information about climatic variability, land use, and plant ecology has accumulated, making it possible to determine causes of change with more confidence. Using nearly two hundred additional triplicate sets of unpublished photographs, The Changing Mile Revisited utilizes repeat photographs selected from almost three hundred stations located in southern Arizona, in the Pinacate region of Mexico, and along the coast of the Gulf of California. Coarse photogrammetric analysis of this enlarged photographic set shows the varied response of the region's major plant species to the forces of change. The images show vegetation across the entire region at sites ranging in elevation from sea level to a mile above sea level. Some sites are truly arid, while others are located above the desert in grassland and woodland. Common names are used for most plants and animals (with Latin equivalents in endnotes) to make the book more accessible to non-technical readers. The original Changing Mile was based upon a unique set of data that allowed the authors to evaluate the extent and magnitude of vegetation change in a large geographic region. By extending the original landmark study, The Changing Mile Revisited will remain an indispensable reference for all concerned with the fragile desert environment.

Book Description
This book is written for scientists and practitioners interested in deepening their knowledge of the sustainable production of bioenergy from wood in tropical and sub-tropical countries. Utilising the value chain concept, this book outlines the necessary aspects for managing sustainable bioenergy production. A wide range of topics is covered including biomass localization, modelling and upscaling, production management in woodlands and plantations, and transport and logistics. Biomass quality and conversion pathways are examined in order to match the conversion technology with the available biomass. A section is dedicated to issues surrounding sustainability. The issues, covered in a life-cycle assessment of the bioenergy system, include socio-economic challenges, local effects on water, biodiversity, nutrient-sustainability and global impacts. Through this holistic approach and supporting examples from tropical and sub-tropical countries, the reader is guided in designing and implementing a value chain as the main management instrument for sustainable wood.

Book Description
How our thirst for more and larger houses is undermining society and what we can do about it. Have we built our way to ruin? Is your desire for that beach house or cabin in the woods part of the environmental crisis? Do you really need a bigger home? Why don’t multiple generations still live under one roof? In The Housing Bomb, leading environmental researchers M. Nils Peterson, Tarla Rai Peterson, and Jianguo Liu sound the alarm, explaining how and why our growing addiction to houses has taken the humble American dream and twisted it into an environmental and societal nightmare. Without realizing how much a contemporary home already contributes to environmental destruction, most of us want bigger and bigger houses and dream of the day when we own not just one dwelling but at least the two our neighbor does. We push our children to "get out on their own" long before they need to, creating a second household where previously one existed. We pave and build, demolishing habitat needed by threatened and endangered species, adding to the mounting burden of global climate change, and sucking away resources much better applied to pressing societal needs. “Reduce, reuse, recycle” is seldom evoked in the housing world, where economists predict financial disasters when "new housing starts" decline and the idea of renovating inner city residences is regarded as merely a good cause. Presenting irrefutable evidence, this book cries out for America and the world to intervene by making simple changes in our household energy and water usage and by supporting municipal, state, national, and international policies to counter this devastation and overuse of resources. It offers a way out of the mess we are creating and envisions a future where we all live comfortable, nondestructive lives. The “housing bomb” is ticking, and our choice is clear—change our approach or feel the blast.

Book Description
This book provides a comprehensive, global synthesis of current knowledge on the potential and challenges associated with the multiple roles, use, management and marketing of non-timber forest products (NTFPs). There has been considerable research and policy effort surrounding NTFPs over the last two and half decades. The book explores the evolution of sentiments regarding the potential of NTFPs in promoting options for sustainable multi-purpose forest management, income generation and poverty alleviation. Based on a critical analysis of the debates and discourses it employs a systematic approach to present a balanced and realistic perspective on the benefits and challenges associated with NTFP use and management within local livelihoods and landscapes, supported with case examples from both the southern and northern hemispheres. This book covers the social, economic and ecological dimensions of NTFPs and closes with an examination of future prospects and research directions.

Book Description
Against a global backdrop of climate change, widespread food insecurity, deforestation and forest degradation, this paper highlights the role of sustainable woodfuel in improving food security. It provides insights into how this role can be strengthened, including through forest management reforms. The widespread availability of woodfuel can present opportunities for employment and sustainable value chains

Book Description
This book traces the economic and biological pattern of forest development from initial settlement and harvest activity at the natural forest frontier to modern industrial forest plantations. It builds from diagrams describing three discrete stages of forest development, and then discusses the management and policy implications associated with each, supporting its observations with examples and data from six continents and from both developed and developing countries. It shows that characteristic distinctions between the three stages make forestry unusual in natural resource management and that effective policy requires different, even contrasting, decisions at each stage. William F. Hyde’s comprehensive discussion covers a wide range of issues, including the impacts of both specific forest policies and broader macroeconomic policies, the unique requirements of current issues such as global warming, biodiversity and tourism, and the complexities of the different forest products industries. Concluding chapters review the roles of the newer institutional landowners, of smaller private and farm landowners, and of public agencies. This highly-original volume reaches far beyond forest economics; it explains what forestry can do for regional development and environmental conservation and what policies designed for other sectors and the macro-economy can do for forestry.

Book Description
This book is based on a Special Issue of the journal LAND that draws together a collection of 11 diverse articles at the nexus of climate change, landscapes, and livelihoods in rural Africa; all explore the links between livelihood and landscape change, including shifts in farming practices and natural resource use and management. The articles, which are all place-based case studies across nine African countries, cover three not necessarily mutually exclusive thematic areas, namely: smallholder farming livelihoods under new climate risk (five articles); long-term dynamics of livelihoods and landscape change and future trajectories (two articles); and natural resource management and governance under a changing climate, spanning forests, woodlands, and rangelands (four articles). The commonalities, key messages, and research gaps across the 11 articles are presented in a synthesis article. All the case studies pointed to the need for an integrated and in-depth understanding of the multiple drivers of landscape and livelihood change and how these interact with local histories, knowledge systems, cultures, complexities, and lived realities. Moreover, where there are interventions (such as new governance systems, REDD+ or climate smart agriculture), it is critical to interrogate what is required to ensure a fair and equitable distribution of emerging benefits.
