Soil Biodiversity In Amazonian And Other Brazilian Ecosystems

The loss of biological diversity has become an increased concern over recent years and is now enshrined in international conventions. Most biodiversity in fact occurs in the soil. Soil organisms (especially bacteria, fungi and soil invertebrates) play a major role in the formation of soil structure and are primary agents of decomposition and are drivers of nutrient cycling, and hence agricultural production.This book reviews soil biodiversity in one of the key biodiversity hotspots of the world, i.e. the Amazon and nearby regions of Brazil. It covers both the tropical savannah and rain forests . The work reported is based on a project "Conservation and Sustainable Management of Below-Ground Biodiversity", executed by TSBF-CIAT with co-financing from the Global Environment Facility (GEF) and implementation support from the United Nations Environment Programme (UNEP). The book represents a major contribution to the literature and will interest those in biodiversity conservation, soil scienceand ecology and biodiversity conservation.

The Amazonia is the largest continuous river basin and rainforest ecosystem in the world. In all aspects it is a natural wonder, and the rainforest with its billions of trees is a vital carbon store that slows down the advance of global warming. It is home to one million indigenous people and some three million species of plants and animals. There have been many climate fluctuations during the last 55 million years of its existence, but never before have “the lungs of the world” been at greater risk than they are today due to uncontrolled fires, expanding agriculture and heavy industrial development in the forms of oil drilling, mining and large hydroelectric dams. Over twelve chapters, this book describes the anthropological, biological and industrial problems facing the Amazonia, and seeks to find new solutions.

This publication contains the proceedings of the Brazilian Agricultural Research Corporation (EMBRAPA)/FAO International Technical Workshop on Biological Management of Soil Ecosystems for Sustainable Agriculture, which was held at EMBRAPA-Soybean headquarters in Londrina, Brazil, from 24 to 27 June 2002. The report includes a review of current understanding and knowledge of the biological management of soil ecosystems through a set of case studies from different production systems and socio-economic conditions, in the areas of indicators and assessment of soil health, adaptive management and innovative technologies. A general discussion and review of lessons learned leading to the main recommendations and further steps for the implementation of an International Soil Biodiversity Initiative are also presented. The financial support was provided through the agricultural biodiversity component of the FAO-Netherlands Partnership Programme.

Describes how farmers manage, maintain, and benefit from biodiversity in agricultural production systems. Includes the most recent research and developments in the maintenance of local diversity at the genetic, species, and ecosystem levels.

This book offers a panorama of recent scientific achievements produced through the framework of the Large-Scale Biosphere-Atmosphere programme (LBA) and other research programmes in the Brazilian Amazon. The content is highly interdisciplinary, with an overarching aim to contribute to the understanding of the dynamic biophysical and societal/socio-economic structure and functioning of Amazonia as a regional entity and its regional and global climatic teleconnections. The target readership includes advanced undergraduate and post-graduate students and researchers seeking to untangle the gamut of interactions that the Amazon’s complex biophysical and social system represent.

The aim of this book is to analyse the current development scenario in the Amazon, using Terra Preta de Índio as a case study. To do so it is necessary to go back in time, both in the national and international sphere, through the second half of the last century to analyse its trajectory. It will be equally important analyse the current issues regarding the Amazon – sustainable development and climate change – and how they still reproduce some of the problems that marked the history of the forest, such as the absence of Amazonian dark earths as a relevant theme to the Amazon. ​In a world in which the environment gains each time more space in the national and international political agenda, the Amazon stands out. Known around the world for its richness, the South-American forest is the target of different visions, often contradictory ones, and it plays with everyone’s imagination. This is where the terra preta de índio – Amazonian Dark Earths - are found, a fertile soil horizon with high concentrations of carbon with anthropic origins, which has generated great interest from the scientific community. Studies on these soils and their so singular characteristics have triggered crucial discussions on the past, present and the future of the entire Amazon region. Despite its singular characteristics, the importance of Amazonian Dark Earths – and a history of a more productive and populated Amazon – was hidden since its discovery around 1880 until 1980, when it is possible to identify the beginning of an increase in the number of research on these soil horizons. These hundred years between the first records and the beginning of the increase in the interest around these soils witnessed structural changes both in the national arena, with the military dictatorship and a change in the place of the Amazon within internal affairs, and in the international arena with changes that reshaped the role of the environment in the political and scientific agendas and the role of Brazil in the global context.

Long-awaited second edition of classic textbook, brought completely up to date, for courses on tropical soils, and reference for scientists and professionals.
