Book Description
The experiments and experiences discussed in Soil Management carefully document crop production systems with well-defined boundaries. These long-term agronomic trials provide a valuable data resource that has, until now, been largely ignored by both the research community and the sustainability experts. With a rigorous definition of sustainability and this data, the sustainability of various cropping systems will be more clearly illustrated than any previous effort. Particular emphasis is given to research involving the tropics and sub-tropics. This book is unique in providing an experimental basis for sustainable management of soil resources. It describes technological options for sustainable management of soil resources and identifies priorities for additional long-term experimentation needed in key ecoregions. Topics discussed include changes in soil processes and properties, environmental quality, soil management, soil dynamics, soil organic matter, and nutrient cycling. Soil Management is for those who ask whether agriculture is sustainable, want to analyze or review sustainability experiments and experiences, or wish to initiate new long-term trials. It is a valuable reference on soil processes and an excellent text for courses in soil management.

Book Description
The long-awaited second edition of this classic textbook expands on the first edition to include advances made in the last four decades, bringing the topic completely up to date. The book addresses critical issues such as whether humanity can feed itself, and whether it can do so in environmentally sound and sustainable ways. Written from agronomic, environmental, and ecological standpoints, the textbook employs a multidisciplinary approach, including policymaking and plant genetic improvements, as well as ecosystem services, climate change, biodiversity, sustainability and resilience. New chapters in this second edition focus on organic carbon in soil, soil biology, soils in relation to livestock production and forestry, and agroforestry. The new edition will again be the go-to textbook for courses on tropical soils, and a reference textbook for soil and agricultural scientists and development professionals working in the tropics.

Book Description
Until recently, the phenomenal economic development of the Asian tigers, Chile, and Malaysia, as well as the sustained economic growth of the United States, painted a very desirable and optimistic picture of free markets, fiscal responsibility, and, more generally, the entire dogma of neoclassical economics. As of the fall of 1998, however, the economies of many tropical countries have contracted severely, and the enthusiasm of the developing tropics for the free market and all of its ancillary policies is decidedly cooler. Have our traditional approaches to economics been failing the developing world? This interdisciplinary book covers the conditions of the developing tropics, the resistance of some of their problems to earlier attempts at solutions, and the use of new tools to develop a much more comprehensive and empirical framework for analysis and decision making. It also presents the development of cutting edge technology that links GIS and modeling approaches with extensive databases on meteorology, soils, agricultural production, and land use. The book discusses whether development is sustainable through a synthesis of demographic, economic, and resource-specific considerations. Costa Rica is uniquely suited to this study because of its size, stage of development, democratic institutions, and national databases.A CD-ROM containing all data and programs, color images, animated models, large data tables, and references accompanies the book. - Links economic and biophysical analyses of sustainability - Presents new tools and approaches for analysis and decision-making - Includes a CD-ROM containing data and programs, color images, animated models, and references

Book Description
Major complex problems confront agricultural policy analysts and development specialists regarding the broad issue of 'agricultural technology.' These topics are reviewed in this volume which consists of 37 chapters, developed from papers presented at a conference held at Airlie House, Virginia, near Washington DC. The authors include leading international authorities from the academic sector, World Bank and agricultural research centers. The chapters are grouped into six parts. The first introductory part is followed by investment as the focus of Part II. In Part III a variety of conceptual and practical issues involved in the transfer of agricultural technology is considered. Part IV includes discussions of concrete technical matters ranging for example from the general to the specific, from plant to animal, and from soil management to irrigation engineering. Emphasis moves from the specifically technological to wider policy issues in Part V and this latter thrust is carried through into the final summarizing section.

Book Description
In 1502, Christopher Columbus named Costa Rica, and while gold and silver never materialized to justify the moniker of rich coast in purely economic terms, scientists and ecotravelers alike have long appreciated its incredible wealth. Wealth in Costa Rica is best measured by its biodiversityhome to a dizzying number of plants and animals, many endemic, it s a country that has long encouraged and welcomed researchers from the world over, and is exemplary in the creation and commitment to indigenous conservation and management programs. Costa Rica is considered to have the best preserved natural resources in Latin America. Approximately nine percent (about 1,000,000 acres) of Costa Rica has been protected in 15 national parks, and a comparable amount of land is protected as wildlife refuges, forest reserves or Indian reservations. This long-awaited synthesis of Costa Rican ecosystems is an authoritative presentation of the paleoecology, biogeography, structure, conservation, and sustainable use of Costa Rica s ecosystems. It systematically covers the entire range of Costa Rica s natural and managed, terrestrial, freshwater and marine ecosystems, including its island systems (Cocos Islands), the Atlantic and Pacific oceans and shores (coasts, coral reefs, mangrove forests), its lowlands (dry, season and wet forests), its highlands (the northern volcanoes and southern Talamanca s), and its estuaries, rivers, lakes, swamps and bogs. The volume s integrated, comprehensive format will be welcomed by tropical and temperate biologists alike, by biogeographers, plant and animal ecologists, marine biologists, conservation biologists, foresters, policy-makers and all scientists, natural history specialists and all with an interest in Costa Rica s ecosystems."
