Book Description
The world's food supply needs to rise significantly, yet both arable and water supplies per capita are decreasing. Not only are modern agricultural methods beyond the reach of those suffering the greatest food insecurity but they are also ecologically damaging, relying upon fossil energy and chemical inputs. This volume offers a collection of innovative and diverse approaches to agricultural development. Documented in 12 case studies, these approaches are reliant upon greater knowledge, skill and labour input, rather than larger capital expenditure. They are shown to increase yield substantially, sometimes doubling or tripling output. This volume presents the concepts and operational means for reorienting agricultural efforts towards these more environmentally friendly and socially desirable approaches in the developed as well as developing world.

Book Description
World soils contain about 1500 gigatons of organic carbon. This large carbon reserve can increase atmospheric concentrations of CO2 by soil misuse or mismanagement, or it can reverse the 'greenhouse' effect by judicious land use and proper soil management. Soil Processes and the Carbon Cycle describes soil processes and their effects on the global carbon cycle while relating soil properties to soil quality and potential and actual carbon reserves in the soil. In addition, this book deals with modeling the carbon cycle in soil, and with methods of soil carbon determinations.

Book Description
Since carbon sequestration in soils reduces the amount of carbon available to the atmosphere, the Kyoto Protocols have heightened interest in soil carbon pools and their effect on carbon fluxes. Assessment Methods for Soil Carbon addresses many of the questions related to the measurement, monitoring, and verification of organic and inorganic carbon in soils. The major topics covered are: carbon pools; soil sampling and preparation, analytical techniques for soil carbon; soil erosion and sedimentation; remote sensing, GIS and modeling; procedures for scaling carbon data from point and local measurements to regional and even national scales; and economic and policy issues. In Assessment Methods for Soil Carbon, leading researchers show that we now have the ability to measure, monitor, and verify changes to soil carbon. The book establishes the need for standardized methods that can be used by anyone, and helps us better understand the link between the pedosphere (soils) and the atmosphere. It also shows the importance of developing links between the economics of carbon sequestration and the amounts sequestered, and highlights the need for scientists and policy makers to interact to ensure that policies fit within the scope of present technologies.

Book Description
Life in rural communities is bound to change with historically unprecedented speed in the coming decades. How will this change be guided by local, national and global policies in order to enhance the livelihoods of rural inhabitants and to overcome the growing division of rural and urban areas? The contributions in this publication, ranging from scientific papers to short reports from practitioners, are grouped around 4 major themes: political and institutional frameworks to foster rural development; natural resources management; broadening the technological base of rural economies; and improved linkages between urban and rural areas. The overall message is unanimous: there is a promising future for the rural areas worldwide if adequate policies can be enforced and more efficient and fair institutions can be created.

Book Description
This volume is written with the objective of covering the basic issues in biological nitrogen fixation such as: the physiology, biochemistry and molecular genetics of nitrogen fixation; and the role of signal molecules and host gene expression in nodulation and nitrogen fixation. The book also details recent developments in biofertilizer technology, such as: the immobilization of cyanobacteria; endophytic nitrogen fixation; and solubilization and mobilization of nutrients by phosphobacteria and VA mycorrhiza and their role as bioinoculants.

Book Description
Soil degradation and nutrient depletion have become serious threats to agricultural productivity in Africa. Soils cannot supply the quantities of nutrients required and yield levels decline rapidly once cropping commences. This book addresses these issues and includes papers from an international symposium held at Cotonou, Benin, October 9-12, 2000, organized by the International Institute of Tropical Agriculture, Ibadan, Nigeria and the Department of Land Management of the Katholieke Universiteit Leuven, Belgium. In five main parts it marks the end of a first phase of collaborative research on "Balanced Nutrient Management Systems for the Moist Savanna and Humid Forest Zones of Africa" and concludes with recommendations, providing essential reading for crop and soil scientists.

Book Description
Nearly two billion people depend on hundreds of millions of smallholder farmers for food security. Yet, these farmers' lives also hang in the balance due to their extreme vulnerability to the risks of soil degradation and depletion, soil exhaustion, climate change, and numerous biotic and abiotic stresses. Soil Management of Smallholder Agriculture
