Desertification: Causes, Impacts and Consequences


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?




The End of Desertification?


Book Description

The question in the title of this book draws attention to the shortcomings of a concept that has become a political tool of global importance even as the scientific basis for its use grows weaker. The concept of desertification, it can be argued, has ceased to be analytically useful and distorts our understanding of social-environmental systems and their resiliency, particularly in poor countries with variable rainfall and persistent poverty. For better policy and governance, we need to reconsider the scientific justification for international attempts to combat desertification. Our exploration of these issues begins in the Sahel of West Africa, where a series of severe droughts at the end of the 20th century led to the global institutionalization of the idea of desertification. It now seems incontrovertible that these droughts were not caused primarily by local land use mismanagement, effectively terminating a long-standing policy and scientific debate. There is now an opportunity to treat this episode as an object lesson in the relationship between science, the formation of public opinion and international policy-making. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept. Despite an increasingly sophisticated understanding of dryland environments and societies, the uses now being made of the desertification concept in parts of Asia exhibit many of the shortcomings of earlier work done in Africa. It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. This book is an effort to critically examine that experience and accelerate the learning process in other parts of the world.




Desertification


Book Description

This book (with a foreword by eminent desertification specialist, Dr. Alan Grainger of Leeds University) provides a synthesis of what desertification means in the present day context of worldwide concerns about land degradation in the face of global (including climate) change, burgeoning populations, urbanization, and loss of biodiversity. It defines and describes desertification in its many forms and examines efforts to combat land degradation. The authors present some models that relate to the current impact of climate change on desertification as well as the medium to long term, and offer case studies on efforts to combat desertification in the major regions of the world. In the last chapter, we attempt to synthesize the whole book in the context of the post-2015 agreements on climate change (the Paris Accord) and the UN Sustainable Development Goals (SDG). Chapters concerning the historical context of desertification consider the definition and meanings associated with the word desertification; discuss the global extent and severity of the many types of desertification; and explain the current status of desertification in the post-2015 context. The book also discusses the impacts of desertification on ecosystems and people along with biodiversity; dust and sand storms from desertified landscapes; and the people affected by desertification. Chapters also focus on desertification and climate change, and consider the nexus between climate, soil, water and people; climate variability, land use and livelihoods affected by desertification are also analyzed. Chapters on combating desertification focus on combating desertification and act as an overview of proven practices with a detailed case study from China. Finally, synthesis and conclusions are consider the future of those affected by desertification, dealing firstly with medium to long term future outlooks and secondly with attempting to sum up the trends.




Climate Change in Deserts


Book Description

A synthesis of the environmental and climatic history of every major desert and desert margin, for researchers and advanced students.




Restoration in Action Against Desertification


Book Description

This publication supports processes related to rural communities’ resilience in implementing land restoration of the Great Green Wall Programme on the ground. It serves a dual purpose of consolidating biophysical operations and socio-economic assessments, and is mainly built on five-year interventions and practical experiences gathered through Action Against Desertification. The first part of the publication is a practical manual expressly created for stakeholders, partners, non-governmental organizations and community-based organizations. Its purpose is to guide the implementation of restoration operations at scale on the ground, as well as to provide detailed practical instructions based on the successful results obtained by Action Against Desertification. The manual describes how to implement an innovative approach to the large-scale restoration of degraded land for small-scale farming. This innovative approach consists of combining enrichment planting of native woody and fodder grass species and the preparation of large-scale land for rainwater harvesting and soil permeability. The second part of the manual introduces a methodology for socio-economic assessments. This easy to-to-use approach is based on household surveys and can be used by socio-economic experts to monitor, evaluate and assess the socio-economic impacts of the large-scale restoration interventions. Household surveys are not only used for impact assessment but can potentially serve to collect useful data needed to plan a restoration intervention. Quantitative information is collected through carefully chosen standardized questions to households as samples.




Sowing Seeds in the Desert


Book Description

Argues that the Earth's deteriorating condition is man-made and outlines a way for the process to be reversed by rehabilitating the deserts using natural farming.




Desert in Modern Literature and Philosophy


Book Description

Aidan explores the ways in which Nietzsche's warning that 'the desert grows' has been taken up by Heidegger, Derrida and Deleuze in their critiques of modernity, and the desert in literature ranging from T.S Eliot to Don DeLillo; from imperial travel writing to postmodernism; and from the Old Testament to salvagepunk.




Combating Desertification with Plants


Book Description

The conference "Combating Desertification with Plants" was held in Beer Sheva, Israel, from November 2-5, 1999, and was attended by 70 participants from 30 countries and/or international organisations. Desertification - the degradation of soils in drylands - is a phenomenon occurring in scores of countries around the globe. The number of people (in semiarid regions) affected by the steady decline in the productivity of their lands is in the hundred millions. The measures required to halt and reverse the process of desertification fall into many categories - policy, institutional, sociological-anthropological, and technical. Although technical "solutions" are not currently in vogue, the conference organizers felt that perhaps the pendulum had swung too far in the direction of "participatory approaches." Hence IPALAC - The International Program for Arid Land Crops - whose function is to serve as a catalyst for optimizing the contribution of plant germplasm to sustainable development in desertification-prone regions - felt the time was opportune for providing a platform for projects where the "plant-driven" approach to development finds expression. Some 45 papers were delivered at the conference, falling into the categories of this volume: Overview, Potential Germplasm for Arid Lands, Introduction, Domestication and Dissemination of Arid Land Plants, Land Rehabilitation, and Mechanisms of Plant Transfer. The conference was funded by UNESCO (Division of Ecological Sciences), the Ministry of Foreign Affairs of Finland, and MASHAV, Israel's Center for International Development Cooperation.




This Is the Way the World Ends


Book Description

Bustle's "17 Best Nonfiction Books Coming Out In September 2018" "With This is the Way the World Ends Jeff Nesbit has delivered an enlightening - and alarming - explanation of the climate challenge as it exists today. Climate change is no far-off threat. It's impacting communities all over the world at this very moment, and we ignore the scientific reality at our own peril. The good news? As Nesbit underscores, disaster is not preordained. The global community can meet this moment — and we must." —Senator John Kerry A unique view of climate change glimpsed through the world's resources that are disappearing. The world itself won’t end, of course. Only ours will: our livelihoods, our homes, our cultures. And we’re squarely at the tipping point. Longer droughts in the Middle East. Growing desertification in China and Africa. The monsoon season shrinking in India. Amped-up heat waves in Australia. More intense hurricanes reaching America. Water wars in the Horn of Africa. Rebellions, refugees and starving children across the globe. These are not disconnected events. These are the pieces of a larger puzzle that environmental expert Jeff Nesbit puts together Unless we start addressing the causes of climate change and stop simply navigating its effects, we will be facing a series of unstoppable catastrophes by the time our preschoolers graduate from college. Our world is in trouble – right now. This Is the Way the World Ends tells the real stories of the substantial impacts to Earth’s systems unfolding across each continent. The bad news? Within two decades or so, our carbon budget will reach a point of no return. But there’s good news. Like every significant challenge we’ve faced—from creating civilization in the shadow of the last ice age to the Industrial Revolution—we can get out of this box canyon by understanding the realities and changing the worn-out climate conversation to one that’s relevant to every person. Nesbit provides a clear blueprint for real-time, workable solutions we can tackle together.




Dry Times


Book Description

With knowledge from our deserts, Australians can reshape the human story. Dry Times: Blueprint for a Red Land provides new insights into how our desert environments and institutions work – and how this affects the people living in them, Aboriginal and non-Aboriginal alike. It shows that the desert offers solutions to the challenges of living in an uncertain and threatening age, teaching us new ways to live, manage scarce resources, and cope with climatic extremes, isolation and lack of water and energy. These lessons apply not only to remote regions, but also to cities and entire nations as humanity faces growing scarcity of vital resources. With vivid examples drawn from Australia's desert life, outback people, animals and plants, Dry Times holds many positive lessons for our nation and humanity in a changing and resource-depleted world.
