Book Description
The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Book Description
The Economics and Organization of Brazilian Agriculture: Recent Evolution and Productivity Gains presents insights on Brazilian agriculture and its impressive gains in productivity and international competitiveness, also providing insightful examples for global policymakers. In Brazil, as in many countries, many economists and policymakers believe that agriculture is a traditional, low-tech sector that crowds out the development of other economic sectors and the country. This book shows that this anti-agriculture bias is ill-informed, and with population growth, rising incomes, urbanization and diet changes – especially in developing countries like China and India – on the rise, the demand for food is expected to double in the next 40 years. Brazil has the natural resources, technology and management systems in place to benefit from this expected growth in food consumption and trade. Through real-world examples, the book shows how other low-latitude countries with tropical climate and soils like Brazil – especially in sub-Saharan Africa – can benefit from the agricultural technology, production, and management systems developed in Brazil. Case studies in each of three key categories, including technology, resource management, and effective government programs provide valuable insights into effective decision-making to maximize the effect of each. - Provides important and practical insights into achievable agricultural options via case studies - Addresses the use of natural resources, technological advances, and management systems to create viable, adaptive economic growth - Applies lessons learned in Brazil to improving both economic and ecological resource-sustainable agriculture for other regions and countries

Book Description
This book represents the first comprehensive edition, in English, on the soils of Brazil, in the challenge of illustrating all the biomes of a country of truly continental dimension. In addition to presenting the first geosystemic view of Brazilian soils, in all geological, geomorphological and environmental aspects, the book also makes a key contribution to the discussion of current topics in Pedology, such as Anthrosols, Technosols, Soil Management trends and sustainability, Pedometrics and advanced techniques of digital soil mapping. The soils of Brazil were conveniently stratified into sectors and treated within the different biomes, without neglecting any area of the Brazilian territory. Considering the aspects of the landscape of occurrence, climates, geomorphology and geology, each pedological region was abundantly documented with soil profile data and many fine original, three-dimensional illustrations and diagrams, made with care by the authors. Among the regions, the most important are the forested Amazon, the Central Plateau with Cerrados, the Caatingas of the northeastern semi-arid region, the Atlantic Forest in all known variants; in addition, the Restingas, Mangroves, Oceanic Islands, Wetlands of the Pantanal and the subtropical regions of the Pampa and Matas de Araucaria. The book is of great importance as the first published work on Brazilian soils, but it is of great interest to geologists and geomorphologists who study the tropics and subtropics, due to the novelty and scope of the work.

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
With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.

Book Description
In 1977, the Volkswagen Foundation sponsored the first of a series of International Symposia on Fire Ecology at Freiburg University, Federal Republic of Germany. The scope of the congresses was to create a platform for researchers at a time when the science of fire ecology was not yet recognized and established outside of North America and Australia. Whereas comprehensive information on the fire ecology of the northern boreal, the temperate, and the mediter ranean biotas is meanwhile available, it was recognized that conside rable gaps in information exist on the role of fire in tropical und sub tropical ecosystems. Thus it seemed timely to meet the growing scientific interest and public demand for reliable and updated infor mation and to synthesize the available knowledge of tropical fire ecology and the impact of tropical biomass burning on global eco system processes. The Third Symposium on Fire Ecology, again sponsored by the Volkswagen Foundation and held at Freiburg University in May 1989, was convened to prepare this first pantropical and multidisci plinary monograph on fire ecology!. The book, in which 46 scientists cooperated, analyzes those fire-related ecosystem processes which have not yet been described in a synoptic way. Following the editor's concept, duplication at previous efforts in describing tropical vegeta tion patterns and dynamics was avoided. Extensive bibliographical sources are given in the reference lists of the chapters.
