change is simply described by the rate of income and rate of loss. Our home's energy budget, our firm's inventory, our nation's debt, and humanity's numbers all have accounts that change at rates that are equal to the inputs minus the outputs. Jenny's "system view" of the soil was carried into the fertile fields of Midwestern American prairies from the laboratories of Switzerland in the late 1920s. Jenny's rate equations provided the other paradigm or world view that, I recall, brought us to the threshold of systems ecology as it later evolved in the second half of the twentieth century. As if world renown in the specialties of pedology and soil chemistry were not enough for one lifetime, excerpts below remind us that Hans Jenny has also been a perceptive outdoor field ecologist since his early Alpine expeditions with Braun Blanquet in the mid 1920s. Jenny's ecosystem studies in the pygmy forest, a further classic example of a soil-plant system "run down" over hundreds of thousands of years since its origin, continue to occupy some of the vigorous retirement time near his farm in Mendocino County. But each specific, quantitative case study, and each research area conserved (with additional hard work) for further study by future generations, fits into Jenny's coherent world view. It is that view, and its legacies of discovery and of tangible landscape preserves, which we are privileged to share with their originator in this volume.

This volume considers soil from two interrelated angles: as a resource and as an environmental medium. It is characterized by a broad-spectrum contextual approach and is modelling oriented. Emphasis is laid on the dynamics of the soil processes in terms of SPAC (Soil-Plant-Air Continuum). The book provides an overview as to how knowledge of the soil processes can be put to practical use to manage soil nutrients, conserve soil moisture, reduce soil degradation, reclaim salt-affected silds, build civil constructions, and prevent soil contamination.

Soil—The Basis of All Terrestrial Life Ancient civilizations and cultures—Mayan, Aztec, Mesopotamian, Indus, and Yangtze—were built on good soils, surviving only as long as soils had the capacity to support them. In the twenty-first century, productive soil is still the engine of economic development and essential to human well-being. The quality of our soil resources, however, is threatened by human-induced and natural perturbations. World Soil Resources and Food Security takes an in-depth look at the availability and status of soil resources in the context of the growing demands of an increasing world population and rising expectations of living standards. This timely reference presents current information on the soil resources available for food production. Presenting innovative strategies for soil and water management, it discusses how to maintain or improve the world’s soil resources in order to increase food production. With the majority of the world’s 1.02 billion food-insecure people concentrated in South Asia and sub-Saharan Africa, several chapters focus on soil resources in these regions. Contributions from renowned scientists deal with topics including: Global food situations World soil resources Soil resources of humid Asia and their acidification Soil resources of South Asia Properties and management of Vertisols Use of radioisotopic techniques in soil management The potential of rain-fed agriculture in the semiarid tropics The status of land degradation Nutrient balance in sub-Saharan Africa The book concludes by outlining the need for further research to generate credible data on soil resources and degradation. This volume is a useful resource for those interested in the state of the soils of the world in relation to food security and environmental quality.

Poor land management has degraded vast amounts of land, reduced our ability to produce enough food, and is a major threat to rural livelihoods in many developing countries. This book provides a thorough analysis of the multifaceted impacts of land use on soils. Abundantly illustrated with full-color images, it brings together renowned academics and policy experts to analyze the patterns, driving factors and proximate causes, and the socioeconomic impacts of soil degradation.
