Since 1985, the University of Hohenheim, Germany, in collaboration with the ICRISAT Sahelian Center, Niger, has pursued the development of improved agricultural systems for smallholder farmers in the fragile agricultural ecosystem of the West African Sahel. Wind erosion is one of the constraints that limits crop production in the region and was therefore a major focus of research. In this book, scientists from different disciplines work together to present a holistic view of this crucial problem and offer possible solutions to farmers in the region. This book is intended for researchers and institutions focusing on sustainable agriculture in the West African Sahel, as well as in other parts of the world where wind erosion affects agricultural production. A deliberate effort has been made to ensure that the book will be comprehensible to a broad readership, including applied researchers, extension specialists, development workers and students working in the field of soil degradation and desertification, as well as national and international policymakers. Those involved in the planning and execution of natural resource protection programs, especially in West Africa, will also gain insights from this book. The book is written in English; the abstracts and the summary chapter are also given in French.

Soil loss for erosion is a natural phenomenon in soil dynamics, influenced by climate, soil intrinsic properties, and morphology, that can both trigger and enhance the process. Anthropic activities, like inappropriate agricultural practices, deforestation, overgrazing, forest fires and construction activities, may exert a remarkable impact on erosion processes or, on the other hand, contribute to soil erosion mitigation through a sustainable management of natural resources. The book is the continuation of previously published "Soil Erosion Studies"; it is organized in a unique section collecting nine chapters focusing on a variety of aspects of the erosion phenomena.

This unique collection of essays examines the environmental problems facing contemporary Nigeria. The relationship between environmental degradation and such social issues as poverty and pollution growth has been impressively analyzed. There is also a well-researched discussion on how government and citizens can work towards achieving sustainable development with long-term solutions to ecological disorders. This book provides a valuable resource for academics and professionals in the general area of environmental management as well as those searching for long-term solutions to Nigeria's particular ecological disorders.

Land degradation from soil erosion has been considered by many to be a problem of significant proportion, affecting some 30-50% of the earth's land surface. At the time of the first publication of this book in 1993, estimates indicated that 10-15 million hectares of land were being lost each year through erosion and salinisation from irrigation and that at such a rate of loss, topsoil reserves on most sloping lands would be depleted within two hundred years. Since humankind's dependency on the land for food is almost total, soil erosion represents a real threat to the security of our food supply. The need for the immediate conservation of the world's soil resources is therefore clear. As part of the response to this need, the International Union for the Conservation of Nature's Commission on Ecology convened a special working group to consider the problem of world soil erosion and to propose practical solutions for soil conservation. This important book presents the outcome of their work.

Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.
