SOIL EROSION AND CONSERVATION




Preface of the Book

Soil erosion is a hazard traditionally associated with agriculture in tropical and semi-arid areas and is important for its long-term effects on soil productivity and sustainable agriculture. It is, however, a problem of wider significance occurring additionally on land devoted to forestry, transport and recreation. Erosion also leads to environmental damage through sedimentation,

Principles of Geotechnical Engineering by BRAJA M. DAS, Seventh Edition

Principle of Geotechnical Engineering,7th edition


This new edition offers an overview of soil properties and mechanics, together with coverage of field Prentice's and basic engineering procedures without changing the basic philosophy in which the text was written originally.


Preface of the Book

Principles of Geo technical Engineering was originally published with a 1985 copyright and was intended for use as a text for the introductory course in geotechnical engineering taken by practically all civil engineering students, as well as for use as a reference book for practicing engineers. The book was revised in 1990, 1994, 1998, 2002, and 2006. 

This Seventh Edition is the twenty-fifth anniversary edition of the text. As in the previous editions of the book, this new edition offers an overview of soil properties and mechanics, together with coverage of field Prentice's and basic engineering procedures without changing the basic philosophy in which the text was written originally.

Report-Status of the World’s Soil Resources

Prepared by Intergovernmental Technical Panel on Soils (ITPS)
Preface | Scope of The State of the World’s Soil Resources


The main objectives of The State of the World’s Soil Resources are: (a) to provide a global scientific assessment of current and projected soil conditions built on regional data analysis and expertise; 
Status of the Soil Resources



(b) to explore the implications of these soil conditions for food security, climate change, water quality and quantity, biodiversity, and human health and wellbeing; and (c) to conclude with a series of recommendations for action by policymakers and other stakeholders. The book is divided into two parts. The first part deals with global soil issues (Chapters 1 to 8). This is followed by a more specific assessment of regional soil change, covering in turn Africa South of the Sahara, Asia, Europe, Latin America and the Caribbean, the Near East and North Africa, North America, the Southwest Pacific and Antarctica. (Chapters 9 to 16). The technical and executive summaries are published separately.
In Chapter 1 the principles of the World Soil Charter are discussed, including guidelines for stakeholders to ensure that soils are managed sustainably and that degraded soils are rehabilitated or restored. For long, soil was considered almost exclusively in the context of food production. However, with the increasing impact of humans on the environment, the connections between soil and broader environmental concerns have been made and new and innovative ways of relating soils to people have begun to emerge in the past two decades. Societal issues such as food security, sustainability, climate change, carbon sequestration, greenhouse gas emissions, and degradation through erosion and loss of organic matter and nutrients are all closely related to the soil resource. These ecosystem services provided by the soil and the soil functions that support these services are central to the discussion in the report.

SOIL ORGANIC CARBON MAPPING Book


Chapter 1 Presentation

Soils provide ecosystem services critical to life on Earth. The Food and Agricultural Organization of the United Nations (FAO) recognizes the need to preserve soil resources from degradation and boost healthy soils. In 2012, FAO members established the Global Soil Partnership (GSP) as a mechanism to improve soil governance at global, regional and national levels. 




The GSP aims to promote sustainable soil management at all levels through different means including normative tools, capacity development, international events and field projects relying on evidence-based science. Understanding the status of a given soil in different land uses, including its properties and functions, and relating this information to the various ecosystem services provided by them, becomes mandatory for sustainable soil management decisions. As the availability of soil data and information is fundamental to underpin these decisions, partners of the GSP decided to establish a Global Soil Information System (GLOSIS) based on a distributed model whereby the system is fed by national soil information systems. In the process of establishing GLOSIS, a number of components are being established, including the International Network of Soil Information Institutions
