Nitrogen Fixation in Tropical Cropping Systems
Nitrogen fixation by leguminous plants is especially important when farmers are trying to minimise fertilizer use for cost or environmental reasons. This second edition of the highly successful book, first published in 1991, contains thoroughly updated and revised material on the theory and practice of nitrogen fixation in tropical cropping systems.
Properties and Management of Soils in the Tropics
Long-awaited second edition of classic textbook, brought completely up to date, for courses on tropical soils, and reference for scientists and professionals.

Agrobiodiversity Management for Food Security
Agrobiodiversity provides most of our food through our interaction with crops and domestic animals. Future global food security is firmly anchored in sound, science-based management of agrobiodiversity. This book presents key concepts of agrobiodiversity management, critically reviewing important current and emerging issues including agricultural development, crop introduction, practical diversity in farming systems, impact of modern crop varieties and GM crops, conservation, climate change, food sovereignty and policies. It will also address claims and misinformation in the subject based on sound scientific principles.

A Handbook of Tropical Soil Biology
This practical handbook describes sampling and laboratory assessment methods for the biodiversity of a number of key functional groups of soil organisms, including insects, earthworms, nematodes, fungi and bacteria. The methods have been assembled and the protocols drafted by a number of scientists associated with the UNEP-GEF funded Conservation and Sustainable Management of Below-Ground Biodiversity Project, executed by the Tropical Soil Biology and Fertility (TSBF) Institute of the International Center for Tropical Agriculture (CIAT). The methods provide a standardized basis for characterizing soil biodiversity and current land uses in terrestrial natural, semi-natural and agroecosystems ...
Organic Farming, Prototype for Sustainable Agricultures
Stakeholders show a growing interest for organic food and farming (OF&F), which becomes a societal component. Rather than questioning whether OF&F outperforms conventional agriculture or not, the main question addressed in this book is how, and in what conditions, OF&F may be considered as a prototype towards sustainable agricultures. The book gathers 25 papers introduced in a first chapter. The first section investigates OF&F production processes and its capacity to benefit from the systems functioning to achieve higher self-sufficiency. The second one proposes an overview of organic performances providing commodities and public goods. The third one focuses on organics development pathways within agri-food systems and territories. As well as a strong theoretical component, this book provides an overview of the new challenges for research and development. It questions the benefits as well as knowledge gaps with a particular emphasis on bottlenecks and lock-in effects at various levels.
A Place Against Time
A Place Against Time is an ethnographically focused environmental study of Montane, New Guinea, where people were among the world's first to cultivate crops some ten millennia ago, and where today an enduring agricultural condition continues. It arranges its account of climate, vegetation topography and geology according to their relationship with the soils of the region occupied by Wola speakers in the Southern Highlands Province of Papua New Guinea, in the Western Pacific. This book breaks new intellectual ground as an ethno-environmental investigation with a soils perspective, ethno-pedology being a little researched topic to date.
