Soil physical measurements are essential for solving many natural resource management problems. This operational laboratory and field handbook provides, for the first time, a standard set of methods that are cost-effective and well suited to land resource survey. It provides: *practical guidelines on the soil physical measurements across a range of soils, climates and land uses; *straightforward descriptions for each method (including common pitfalls) that can be applied by people with a rudimentary knowledge of soil physics, and *guidelines on the interpretation of results and integration with land resource assessment. Soil Physical Measurement And Interpretation for Land Evaluation begins with an introduction to land evaluation and then outlines procedures for field sampling. Twenty detailed chapters cover pore space relations, water retention, hydraulic conductivity, water table depth, dispersion, aggregation, particle size, shrinkage, Atterburg limits and strength. The book includes procedures for estimating soil physical properties from more readily available data and shows how soil physical data can be integrated into land planning and management decisions.

The goal of the manual is to supply an operational tool for pedologists, agronomists, environmentalists, and all of the other specialists who carry out land evaluation for agriculture and forestry or, more generally, stakeholders and policy makers who make decisions at the local level based on the knowledge of the nature of soil. Discussion of the topics is not only technical and operational, but also in-depth and didactic; therefore, the text may also be used as a valid complement for students majoring in subjects that involve soil use, management and conservation. The literature offers a wide choice of possible soil and land evaluation methods, while knowledge of the relationships existing between the physical characteristics of lands, particularly those of soils, and the requirements of specific uses is limited.

This book is designed to present those principles and techniques for land appraisal which are applicable to all developing countries. Examples of specific situations in which these techniques have been or might be adopted are taken primarily from monsoonal and equatorial Asia. It is in this region that the land/food/population problem is most acute. It is also the writer's region of specialization; over the past ten years out of a total of some twenty-five years working in or closely concerned with Asia, an attempt has been made to examine the major problems ofland potential in relation to rural economy and nutrition in the whole region, and in particular to show to what extent its different parts resemble or differ from each other. The geographical scope comprises mainland southern, southeast and east Asia, from Pakistan to the People's Republic of China and Korea, with the insular monsoonal and equatorial lands of Sri Lanka, Indonesia, East Malaysia, Philippines, Taiwan and Japan (part). International and bilateral agencies and specialists outside Asia repeatedly insist that Asia must learn to feed itself from the produce of its own land, or from imported foods paid for by the exports of primary and secondary commodities and of manufactured products to the developed world.

First published in 1991. This is a more portable version of the Booker Tropical Soil Manual, in which the format (and weight) of the first edition have been reduced whilst retaining as much as possible of the original clarity. It also includes new content and appendices that cover the revised FAO publications on soil classification and on water quality for agriculture.

Increased global demand for land posits the need for well-designed country-level land policies to protect long-held rights, facilitate land access and address any constraints that land policy may pose for broader growth. While the implementation of land reforms can be a lengthy process, the need to swiftly identify key land policy challenges and devise responses that allow the monitoring of progress, in a way that minimizes conflicts and supports broader development goals, is clear. The Land Governance Assessment Framework (LGAF) makes a substantive contribution to the land sector by providing a quick and innovative tool to monitor land governance at the country level. The LGAF offers a comprehensive diagnostic tool that covers five main areas for policy intervention: Legal and institutional framework; Land use planning, management and taxation; Management of public land; Public provision of land information; and Dispute resolution and conflict management. The LGAF assesses these areas through a set of detailed indicators that are rated on a scale of pre-coded statements (from lack of good governance to good practice). While land governance can be highly technical in nature and tends to be addressed in a partial and sporadic manner, the LGAF posits a tool for a comprehensive assessment, taking into account the broad range of issues that land governance encompasses, while enabling those unfamiliar with land to grasp its full complexity. The LGAF will make it possible for policymakers to make sense of the technical levels of the land sector, benchmark governance, identify areas that require further attention and monitor progress. It is intended to assist countries in prioritizing reforms in the land sector by providing a holistic diagnostic review that can inform policy dialogue in a clear and targeted manner. In addition to presenting the LGAF tool, this book includes detailed case studies on its implementation in five selected countries: Peru, the Kyrgyz Republic, Ethiopia, Indonesia and Tanzania.

'A wonderfully international and up-to-date perspective on strategic environmental assessment of land use plans by leading experts in the field. Strategic Environmental Assessment and Land Use Planning covers not only how much such SEAs are carried out and in what context, but whether they are effective and why. It provides invaluable insights for practitioners and researchers in this rapidy evolving field'Riki Therivel, author of Strategic Environmental Assessment in ActionStrategic Environmental Assessment and Land Use Planning provides an authoritative, international evaluation of the SEA of land use plans. The editors place the SEA of land use plans in context, and uniquely qualified contributors then evaluate systems in Canada, Denmark, Germany, Hong Kong, Hungary, Ireland, The Netherlands, New Zealand, Portugal, South Africa, Sweden, the United Kingdom, the United States and the World Bank. These chapters provide a description of the context in each country, a case study of the use of SEA in land use planning and an evaluation of each SEA system against a set of generic criteria specially designed to anlayse different aspects of SEA. The contributors critically review each SEA system, SEA process and SEA outcome, and conclude by summarizing their findings. The editors draw the various national perspectives together in a final chapter and derive widely applicable conclusions about SEA and land use planning.This book is a core text for all students in environmental assessment, land use planning, environmental science, environmental management, development studies, geography, landscape design and law and engineering. It is also essential reading for all governments and environmental regulators, academics, researchers and environmental and planning consultants worldwide who are involvedin SEA research, practice and training.

The study of soils has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experi enced. This has led to an increase in land degradation. Land degradation is one of the most severe problems facing mankind. Volume 11 of Advances in Soil Science was devoted entirely to this critical area of soil science. The editors of that volume, R. Lal and B.A. Stewart, defined soil degradation as the decline in soil quality caused by its misuse by humans. They further stated that soil degradation is a major concern for at least two reasons. First, it undermines the productive capacity of an ecosystem. Second, it affects global climate through alterations in water and energy balances and disruptions in cycles of carbon, nitrogen, sulfur, and other elements. Through its impact on agricultural productivity and environment, soil deg radation leads to political and social instability, enhanced rate of deforesta tion, intensive use of marginal and fragile lands, accelerated runoff and soil erosion, pollution of natural waters, and emission of greenhouse gases into the atmosphere. In fact, soil degradation affects the very fabric of mankind.
