Book Description
Predictive Soil Mapping (PSM) is based on applying statistical and/or machine learning techniques to fit models for the purpose of producing spatial and/or spatiotemporal predictions of soil variables i.e. maps of soil properties and classes at different resolutions. It is a multidisciplinary field combining statistics, data science, soil science, physical geography, remote sensing, geoinformation science and a number of other sciences. Predictive Soil Mapping with R is about understanding the main concepts behind soil mapping, mastering R packages that can be used to produce high quality soil maps, and about optimizing all processes involved so that also the production costs can be reduced. The online version of the book is available at: https: //envirometrix.github.io/PredictiveSoilMapping/ Pull requests and general comments are welcome. These materials are based on technical tutorials initially developed by the ISRIC's Global Soil Information Facilities (GSIF) development team over the period 2014?2017

Book Description
As a living substrate, soil is critical to the function of Earth's geophysical and chemical properties. Soil also plays a major role in several human activities, including farming, forestry, and environmental remediation. Optimizing those activities requires a clear understanding of different soils, their function, their composition and structure, and how they change over time and from place to place. Although the importance of soil to Earth's biogeochemical cycles and to human activities is recognized, the current systems in place for monitoring soil properties - including physical, chemical, and, biological characteristics - along with measures of soil loss through erosion, do not provide an accurate picture of changes in the soil resource over time. Such an understanding can only be developed by collecting comprehensive data about soils and the various factors that influence them in a way that can be updated regularly and made available to researchers and others who wish to understand soils and make decisions based on those data. The National Academies of Sciences, Engineering, and Medicine convened key stakeholders in a workshop on March 2-4, 2021, to discuss the development of a dynamic soil information system. Workshop discussions explored possiblities to dynamically and accurately monitor soil resources nationally with the mutually supporting goals of (1) achieving a better understanding of causal influences on observed changes in soil and interactions of soil cycling of nutrients and gases with earth processes, and (2) providing accessible, useful, and actionable information to land managers and others. This publication summarizes the presentation and discussion of the workshop.

Book Description
Guidelines for Surveying Soil and Land Resources promotes the development and implementation of consistent methods and standards for conducting soil and land resource surveys in Australia. These surveys are primarily field operations that aim to identify, describe, map and evaluate the various kinds of soil or land resources in specific areas. The advent of geographic information systems, global positioning systems, airborne gamma radiometric remote sensing, digital terrain analysis, simulation modelling, efficient statistical analysis and internet-based delivery of information has dramatically changed the scene in the past two decades. As successor to the Australian Soil and Land Survey Handbook: Guidelines for Conducting Surveys, this authoritative guide incorporates these new methods and techniques for supporting natural resource management. Soil and land resource surveyors, engineering and environmental consultants, commissioners of surveys and funding agencies will benefit from the practical information provided on how best to use the new technologies that have been developed, as will professionals in the spatial sciences such as geomorphology, ecology and hydrology.

Book Description
Signi?cant technological advances have been few and far between in the past approximately one hundred years of soil survey activities. Perhaps one of the most innovative techniques in the history of soil survey was the introduction of aerial photographs as base maps for ?eld mapping, which replaced the conventional base map laboriously prepared by planetable and alidade. Such a relatively simple idea by today’s standards revolutionized soil surveys by vastly increasing the accuracy and ef?ciently. Yet, even this innovative approach did not gain universal acceptance immediately and was hampered by a lack of aerial coverage of the world, funds to cover the costs, and in some cases a reluctance by some soil mappers and cartog- phers to change. Digital Soil Mapping (DSM), which is already being used and tested by groups of dedicated and innovative pedologists, is perhaps the next great advancement in delivering soil survey information. However, like many new technologies, it too has yet to gain universal acceptance and is hampered by ignorance on the part of some pedologists and other scientists. DSM is a spatial soil information system created by numerical models that - count for the spatial and temporal variations of soil properties based on soil - formation and related environmental variables (Lagacheric and McBratney, 2007).

Book Description
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.

Book Description
Countries of the Near East vary in the type, quantity and format of the inventories of their land resources. Quite often, these data are sporadic, incomplete, out of date or based on diverse systems of land and soil classification and mapping. There is a need for the establishment of a user-friendly database on land and water Resources for each country, to be easily available at the desktop of land use planners and decision makers. Land resources information systems experiences in the countries are presented in this document, as well as recommendations for future collaboration in database development, reporting and exchange of information, expertise and experiences in land and water management in the region and the implementation of regional projects.
