Book Description
We are now entering the third decade of the 21st century, and recent drylands-focused research has led to major advances in our understanding of the coupled roles of climatic, edaphic, biotic, and anthropogenic processes in dryland ecosystem function, degradation, and sustainable management. Frontiers has organized a series of Research Topics to highlight the latest advancements in science in order to be at the forefront of science in different fields of research. This editorial initiative, led by Professor Niall Hanan, Specialty Chief Editor of the Drylands section, together with Dr. Lindsay Hutley, is focused on new insights, novel developments, current challenges, latest discoveries, recent advances, and future perspectives in the drylands field.

Book Description
Ecosystems and Human Well-Being is the first product of the Millennium Ecosystem Assessment, a four-year international work program designed to meet the needs of decisionmakers for scientific information on the links between ecosystem change and human well-being. The book offers an overview of the project, describing the conceptual framework that is being used, defining its scope, and providing a baseline of understanding that all participants need to move forward. The Millennium Assessment focuses on how humans have altered ecosystems, and how changes in ecosystem services have affected human well-being, how ecosystem changes may affect people in future decades, and what types of responses can be adopted at local, national, or global scales to improve ecosystem management and thereby contribute to human well-being and poverty alleviation. The program was launched by United National Secretary-General Kofi Annan in June 2001, and the primary assessment reports will be released by Island Press in 2005. Leading scientists from more than 100 nations are conducting the assessment, which can aid countries, regions, or companies by: providing a clear, scientific picture of the current sta

Book Description
Drylands cover 41 percent of the earth' s terrestrial surface. The urgency of and international response to climate change have given a new place to drylands in terms both of their vulnerability to predicted climate change impacts and their potential contribution to climate change mitigation. This book aims to apply the new scientific insights on complex dryland systems to practical options for development. A new dryland paradigm is built on the resources and capacities of dryland peoples, on new and emergent economic opportunities, on inward investment, and on the best support that dryland science can offer.

Book Description
With climate change impacts already felt in the world’s drylands, there is an urgent need for action, at various scales and initiated by different stakeholders, to ensure the sustainability of food production and livelihoods in these regions in the coming decades. There is also the need to rapidly establish baselines, assess and start monitoring progress on sustainability, emerging as result of the action taken. To aid in this effort, this paper provides a short list of expected transformations (under each of the three sustainability pillars) for guiding the planning and implementation of policy, governance and practice-level actions. Gender and indigenous people’s rights and knowledge will be considered cross-cutting issues. The expected transformations will be shared with and agreed by dryland experts and practitioners and will be complemented with additional relevant information sources and indicators. However, it is recommended that national and subnational governments, programmes, projects and individual practitioners and experts define the indicators they will use for measuring their own progress towards the expected transformations, based on the availability of data and specific national and local conditions.The paper will also present case studies portraying actions that have led to progress in sustainability and are directly related to the expected transformations. A related policy brief Blooming Drylands will complement the paper and offer practical recommendations on how policymakers can reach the expected transformations.

Book Description
An argument that the perception of arid lands as wastelands is politically motivated and that these landscapes are variable, biodiverse ecosystems, whose inhabitants must be empowered. Deserts are commonly imagined as barren, defiled, worthless places, wastelands in need of development. This understanding has fueled extensive anti-desertification efforts—a multimillion-dollar global campaign driven by perceptions of a looming crisis. In this book, Diana Davis argues that estimates of desertification have been significantly exaggerated and that deserts and drylands—which constitute about 41% of the earth's landmass—are actually resilient and biodiverse environments in which a great many indigenous people have long lived sustainably. Meanwhile, contemporary arid lands development programs and anti-desertification efforts have met with little success. As Davis explains, these environments are not governed by the equilibrium ecological dynamics that apply in most other regions. Davis shows that our notion of the arid lands as wastelands derives largely from politically motivated Anglo-European colonial assumptions that these regions had been laid waste by “traditional” uses of the land. Unfortunately, such assumptions still frequently inform policy. Drawing on political ecology and environmental history, Davis traces changes in our understanding of deserts, from the benign views of the classical era to Christian associations of the desert with sinful activities to later (neo)colonial assumptions of destruction. She further explains how our thinking about deserts is problematically related to our conceptions of forests and desiccation. Davis concludes that a new understanding of the arid lands as healthy, natural, but variable ecosystems that do not necessarily need improvement or development will facilitate a more sustainable future for the world's magnificent drylands.

Book Description
This edited volume examines the changes that arise from the entanglement of global interests and narratives with the local struggles that have always existed in the drylands of Africa, the Middle East, and Central Asia/Inner Asia. Changes in drylands are happening in an overwhelming manner. Climate change, growing political instability, and increasing enclosures of large expanses of often common land are some of the changes with far-reaching consequences for those who make their living in the drylands. At the same time, powerful narratives about the drylands as ‘wastelands’ and their ‘backward’ inhabitants continue to hold sway, legitimizing interventions for development, security, and conservation, informing re-emerging frontiers of investment (for agriculture, extraction, infrastructure), and shaping new dryland identities. The chapters in this volume discuss the politics of change triggered by forces as diverse as the global land and resource rush, the expansion of new Information and Communication Technologies, urbanization, the COVID-19 pandemic, and the spread of violent extremism. While recognizing that changes are co-produced by differently positioned actors from within and outside the drylands, this volume presents the dryland’s point of view. It therefore takes the views, experiences, and agencies of dryland dwellers as the point of departure to not only understand the changes that are transforming their lives, livelihoods, and future aspirations, but also to highlight the unexpected spaces of contestation and innovation that have hitherto remained understudied. This edited volume will be of much interest to students, researchers, and scholars of natural resource management, land and resource grabbing, political ecology, sustainable development, and drylands in general.

Book Description
This edited volume is devoted to the examination of the implications of the inevitable changes wrought by global change on the welfare and livelihoods of tens of millions of people who live in dryland regions. Global change is more than just climate change and the ramifications of changing trade patterns (geopolitical and economic aspects), the shift to the market economy, demographic factors (population growth, urbanization and re-settlement), receive attention here. Land use change specialists, policy makers and natural resource management agencies will find the book very useful. Chapters focus on examples that are drawn from a number of sources including previously unpublished studies on the impact of climate change, markets and economics on pastoralist and dryland farming households. The key focus is to provide readers with insights into the real world implications of change (including an analysis of the drivers of change) on these vulnerable groups within dryland societies. The role of humans as agents of these changes is canvassed. A regional analysis of the world's drylands is also performed including those in Australia, Argentina, India, North America, China, North Africa, Central Asia and Southern Africa.

Book Description
It now seems incontrovertible (as Alessandra Giannini has demonstrated) that the series of Sahelian droughts that began in the early 1970s were driven by changes in sea surface temperatures and that they were not caused by local land use mismanagement in the Sahel itself. Combined with the apparent re-greening of the Sahel, these findings effectively close a long-standing policy and scientific debate (in which the lead authors of this book participated) on the causes and extent of desertification in the Sahel. The opportunity now presents itself to treat this debate as a historical object lesson in the relationship between science, the formation of public opinion, and international policy-making in the context of climate change. In short, what might the ‘great Sahelian desertification boondoggle’ have to tell us about current attempts to come to grips with climate change?
