Loess is a product of aeolian deposition during the Quaternary glaciation cycles and covers approximately 6% of the Earth’s land. The Loess Plateau of China, which is home to a population of nearly three hundred million, has the thickest and most complete loess strata, where loess geohazards occur most frequently due to the weak geoenvironment and dense human activities. In recent years, the engineering geological characteristics of loess and geohazards in loess areas have gradually received increasing attention from academic researchers. This book reviews an informative collection of up-to-date literature in this field. It presents the unique features of loess and loess geohazards, and provides a strong foundation for future study via eight systematically structured chapters, e.g., origin and spatial distribution, loess landforms, microstructure, physical properties, permeability, shear strength, tensile strength, and loess geohazard. It can serve as a principal reference for researchers, practical engineers and technicians who are engaged in loess geology and surface processes, and is suitable especially for undergraduate and postgraduate students in the field of loess engineering geology.

This book presents state-of-the-art scientific evidence and technological innovations to restore lands on the Loess Plateau of China, known worldwide for its serious land degradation and desertification problems. Supported by a rapidly developing Chinese economy and the dissemination of effective technology, the Grain-for-Green Project and Western Development Action launched by the Chinese government have resulted in successful ecological restoration and protection over the past 30 years. These programs have contributed not only to conservation of soil and water, but also to economic development. At the same time, however, these developmental interventions have brought new challenges that have not yet been fully addressed. The book describes (1) case studies of success and failure in practice, including rare success stories of combating desertification; (2) technical issues such as erosion control and breeding of stress-tolerant plant species, and socioeconomic measures taken by the Chinese government and lending policies with support from the World Bank; and (3) comprehensive measures against desertification, such as water and wind erosion, salinization, and deforestation. This volume is recommended for researchers and students above the undergraduate level in diverse fields including soil science, rural engineering, social technology and civil engineering, biology, ecology, climatology, physical and human geography, and developmental economics, among others. It also serves as a valuable resource for engineers, government officials, and NPOs and NGOs involved in afforestation, ecological restoration, combating desertification, disaster prevention, and sustainable rural development.

A lavishly illustrated study of landslides and debris flows on theLoess Plateau of north-central China where dense rural populationand human activity has greatly increased landslide hazard. The Loess Plateau lies in the middle reaches of the Yellow Riverand there are a number of cities housing more than a millionpeople. Landslides are triggered by heavy rainstorms andearthquakes have been a recurrent hazard in the loess terrain forover two millennia. The contributors to this book set out with a number of goalsincluding: * establishing the role of bedrock relief in landsliding * studying the nature of the hydrological system within the loessslopes * characterising the modes of failure of the loess fabric * producing a dynamically-based classification of loesslandslides * 'ultimately' establishing criteria for a simple warning systemfor loess slope failure, together with an advisory scheme for localpopulation response to landslide warnings. This book includes over forty colour maps unique in their contentand coverage, showing for the first time the detailed distributionof landslides in the thick loess terrain of eastern Gansu Province,North China.

"I've seen the Sudan, traveled in South and Central America and been all over Europe, but I've never seen what I've been able to see on this tour [of the Loess Plateau, China]." -Ed Skidmore, soil scientist, Wind Erosion Research Unit of the Agricultural Research Service, USDA, Manhattan, Kansas Overpopulation is at the core of most environmental problems. The impacts of continued growth-with world population reaching 6 billion in October 1999-are felt in most parts of the world. China, the most populous nation, illustrates many of the pivotal problems-and solutions. Although China faces the same effects of overpopulation as the rest of the world, it still feeds over a billion people on a tillable area that allows about one tenth of a hectare per person. The country's efforts to tie together soil and water conservation, dryland farming, and economic development have been largely successful. Soil Erosion and Dryland Farming explores these trials and the lessons learned from them. Copublished with the Soil and Water Conservation Society, this exhaustive text consists of the rewritten proceedings from the Society's conference held in Yangling, Shaanxi, China. It covers dryland farming systems and soil water management, environmental quality and sustainability, and erosion control techniques as they relate primarily to Mainland China. With additional global examples and a balance between conceptual and applied studies, it covers some of the most progressive work in soil erosion control and dryland farming from around the world. Soil exposure while land lies fallow is one of the greatest risks in dryland farming. New procedures and kinds of tillage help control erosion and improve water intake. Soil Erosion and Dryland Farming presents these techniques and technologies to give you a forward-looking perspective into the field, as well as the larger problem of tailoring food production to sustain the population.

Explores soil as a nexus for water, chemicals, and biologically coupled nutrient cycling Soil is a narrow but critically important zone on Earth's surface. It is the interface for water and carbon recycling from above and part of the cycling of sediment and rock from below. Hydrogeology, Chemical Weathering, and Soil Formation places chemical weathering and soil formation in its geological, climatological, biological and hydrological perspective. Volume highlights include: The evolution of soils over 3.25 billion years Basic processes contributing to soil formation How chemical weathering and soil formation relate to water and energy fluxes The role of pedogenesis in geomorphology Relationships between climate soils and biota Soils, aeolian deposits, and crusts as geologic dating tools Impacts of land-use change on soils The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the Editors

In geomorphology, landform inheritance refers to the inherited relationship of different landform morphologies in a certain area during the evolutionary process. This book studies loess landform inheritance based on national basic geographic data and GIS spatial analysis method. It reveals the Loess Plateau formation mechanism and broadens the understanding of spatial variation pattern of loess landform in the Loess Plateau.
