Book Description
"The Atlas describes soil as habitat for the diversity of organisms that live under our feet. At the same time, it draws attention to the threats to soil biodiversity, such as invasive species, pollution, intensive land use practices or climate change. The Atlas provides current solutions for a sustainable management of soils. It was coordinated by the JRC and the Global Soil Biodiversity Initiative (www.globalsoilbiodiversity.org) with more than 70 contributing organisations and several hundred individual contributions. It illustrates the diversity of soil organisms, explains their geographical and temporal distribution, the ecosystem functions and services provided by soil biota. Most importantly, it draws attention to the myriad of threats to soil biodiversity. These include inappropriate land management practices (e.g. deforestation, land take for infrastructure development), agricultural systems, over-grazing, forest fires and poor water management (both irrigation and drainage). Other practices such as land conversion from grassland or forest to cropped land result in rapid loss of soil carbon, which indirectly enhances global warming. The Atlas shows that mismanaging soils could exacerbate the effects of climate change, jeopardise agricultural production, compromise the quality of ground water and worsen pollution. It also proposes solutions to safeguard soil biodiversity through the development of policies that directly or indirectly target soil health, leading to a more sustainable use."--

Book Description
The book compiles the main ideas and methodologies that have been proposed and tested within these last fifteen years in the field of Digital Soil Mapping (DSM). Begining with current experiences of soil information system developments in various regions of the world, this volume presents states of the art of different topics covered by DSM: Conception and handling of soil databases, sampling methods, new soil spatial covariates, Quantitative spatial modelling, Quality assessment and representation of DSM outputs. This book provides a solid support to students, researchers and engineers interested in modernising soil survey approaches with numerical techniques. It is also of great interest for potential soil data users. * A new concept to meet the worldwide demand for spatial soil data * The first compilation of ideas and methodologies of Digital Soil Mapping * Offers a variety of specialities: soil surveying, geostatistics, data mining, fuzzy logic, remote sensing techniques, Geographical Information Science,...* Written by 82 researchers from 13 different countries

Book Description
INTRODUCTION 'Data and information are essential building blocks of science. Many types of data, including extant historical data which have newly appreciated scientific importance for the analysis of changes over time, are not being used for research because they are not available in digital formats' (International Council for Science, 2004). Maps made in the past remain the backbone for present and future studies. Soil maps are resources for researchers in many fields apart from soil science; they are the source of databases, related to and dependent on soils, used to monitor land degradation and improvement, changes in land use and water resources, and to predict climatic and other environmental changes. Less and less new, fundamental soil data are being produced these days; the older data and information are being pumped around more and more. Therefore it is vital to preserve the older data (in this case maps) as they are building blocks of most current soil information. The user of present-day, derived information should have easy access to the source material, if only to assess the reliability of the derived material. But, in many countries, soil maps are being lost because of lack of proper attention to storage and retrieval, often compounded by a loss of institutions that have been responsible for the acquisition and maintenance of soil and land resources data. This problem is acute in developing and transitional countries where valuable data, currently only available on paper, must be digitized before they are lost forever. In Africa, though not only in Africa, this type of information is rapidly being lost; much is already lost. The digitization of the African maps will enable the African countries to recover and re-use their soil information. Translation of soil information from paper maps and reports into digital format is a prerequisite of the next step - the development of a digital information system on soil and terrain that may be drawn upon for manifold applications. BACKGROUND For some 40 years, ISRIC World Soil Information has been providing significant support to the international science community by collecting and archiving regional-, national- and global-scale maps of soils and land resources. Despite effective procedures for storage and maintenance, most organizations involved in archiving struggle to arrest the deterioration of paper maps and the quality of information they contain. Deterioration occurs for various reasons that include handling, transport, exposure to light, moisture and atmospheric pollution. Realizing the need to conserve the information on existing maps, which underpin the fast-developing thematic mapping strategies to support soil protection, the Institute of Environment and Sustainability (IES) in the European Commission (Italy) and ISRIC World Soil Information initiated the European Digital Archive of Soil Maps (EuDASM). The immediate objective is to transfer soil information into digital format, with the maximum resolution possible, to preserve the information of paper maps that are vulnerable to deterioration. Beyond data rescue, the archive is expected to develop into a common platform for storing soil maps from around the world and making the information readily accessible. Organisations that maintain soil map archives in paper form, and wishing to conserve this information by transferring it into digital form, are invited to join the EuDASM programme. The initiative for this programme was taken by Dr Luca Montanarella of the European Joint Research Centre and Dr Otto Spaargaren of ISRIC World Soil Information in October 2004. The first level success for this initiative was figured out by completion of the around 2000 soil maps pertaining to the African continent. Through this digitization programme the map quality and precision of information were preserved against further loss assuming to be required for future use by land resources specialists.

Book Description
GlobalSoilMap: Basis of the global spatial soil information system contains contributions that were presented at the 1st GlobalSoilMap conference, held 7-9 October 2013 in Orléans, France. These contributions demonstrate the latest developments in the GlobalSoilMap project and digital soil mapping technology for which the ultimate aim is to produce a high resolution digital spatial soil information system of selected soil properties and their uncertainties for the entire world. GlobalSoilMap: Basis of the global spatial soil information system aims to stimulate capacity building and new incentives to develop full GlobalSoilMap products in all parts of the world.

Book Description
This book presents the basic concepts of quantitative soil science and, within this framework, it seeks to construct a new body of knowledge. There is a growing need for quantitative approach in soil science, which arises from a general demand for improved economic production and environmental management. Pedometrics can be defined as the development and application of statistical and mathematical methods applicable to data analysis problems in soil science. This book shows how pedometrics can address key soil-related questions from a quantitative point of view. It addresses four main areas which are akin to the problems of conventional pedology: (i) Understanding the pattern of soil distribution in character space – soil classification, (ii) Understanding soil spatial and temporal variation, (iii) Evaluating the utility and quality of soil and ultimately, (iv) Understanding the genesis of soil. This is the first book that address these problems in a coherent quantitate approach.
