This is a volume in the new IYPE series commemorating the UN International Year of Planet Earth. It presents the current state-of-the-art in soil sciences, and ways forward for a sustainable future.The book provides a wealth of information on soils offered by new airborne and space-borne sensors, with unprecedented detail, accuracy, rapid regional and global coverage, and also information from deep below the surface. This new data is used in climate models, agricultural and forest production estimates, assessment of land degradation and improvement, water resources management, and estimation of erosion and sedimentation. The book discusses how good intelligence can support interventions to arrest salinity, identify shallow groundwater resources, design water storages and other engineering works, and assess land suitability for particular uses. TOC:1.Introduction: Context of Land Use and Management.- Part 1.The Status of the Soils. 2.The Soils.- 3.Soil Composition and Texture.- 4.Soil Mineralogy and Elemental Composition.- 5.Absorption Capacity and Reaction.- 6.Soluble Salts and Soil Solution.- 7.Humus - the Mainspring of Fertility.- 8.The Nitrogen Riddle.- 9.Phosphorus and Sulphur Budgets.- 10.Life in the Soil.- 11.Soil Structure, Soil Water and Drought.- 12.The Chernozem Family.- 13.Land Degradation and Accommodating Soil Diversity.- 14.Society's Perspective.- Part 2.Principles of Ecological Agriculture. 15.Biological Cycles.- 16.Soil Health and Quality.- 17.Farming and Soil Health.- 18.The Past, Present and Future of Chemozem.

Teachers, students, experts, policymakers, and citizen activists all should welcome this authoritative, systematic, single-volume sourcebook of who makes foreign policy, how it is made, and what U.S. policy has been since the 1960s.

This report examines the scientific basis for the use of remotely sensed data, particularly Normalized Difference Vegetation Index (NDVI), primarily for the assessment of land degradation at different scales and for a range of applications, including resilience of agro-ecosystems.

The volume offers a rich synthesis of political science research on Latin America over the past 30 years and offers a wealth of information to anyone interested in the area--from the beginning student to the area specialist.

Ideal for student research and debate, this is the first single-volume reference work to examine, country by country, the history of U.S. involvement in 24 Latin American and Caribbean nations.

This book examines the best soil in the world - the black earth or chernozem - showing how it is rapidly being degraded by industrial farming. The authors describe principles for sustainable agriculture that can reverse this trend, and feed the world.

Contains chapters exploring drug wars, immigration issues, terrorism, youth gangs, government corruption, controversy over oil and political instability. This book analyses over 30 security-based hot spots within the geographical regions including: the Zapatista Rebellion; the Darien Gap controversy; Evo Morales; Shining Path; and, the Falklands.

This book provides over 260 entries on U.S. presidents, Latin American politicians, covert operations, policies, and major events since the early 1800s that define the contentious relations between the United States and the Latin American and Caribbean region.From the Monroe Doctrine to NAFTA, the tone of U.S.-Latin America relations has been set by the United States, and largely to its benefit. Dent compiles more than 260 A-to-Z entries that detail the key people, events, treaties, wars, and concepts that have gone into the making of the often contentious relations between the United States and the Latin American and Caribbean region. Entries conclude with suggested readings and are thoroughly cross-referenced. A thematic index guides users to related entries, and an extensive bibliography includes a list of key works central to the study of U.S.-Latin American relations. There is also a separate list of relevant online resources. The entire work is also thoroughly indexed.Useful for students and researchers of international politics within the Western hemisphere, Dent's historical dictionary covers items ranging from pro-slavery filibusterers adventuring in Central America, Dollar Diplomacy, Anti-Americanism, Banana Wars, the Reagan Doctrine, Sandinistas, friendly Dictators, Che Guevara, to the impact of the events of September 11, 2001 on Latin America, among many others.
