Available in PDF, EPUB and Kindle. Book excerpt: Can a continuous growth of agriculture be achieved in the sub-Sahara region without inducing irreversible damage to the ecosystem? Until now, doubts have been expressed as to the actual capacity of the soils to sustain a desirable increase of production which can match the requirements of a fast-growing population. Thirty years of investigation and a renewed comprehensive interpretation of research data on soil fertility show that a sustainable agriculture growth could be a practical possibility in a savannah region.
Download or read book Working with Dynamic Crop Models written by Daniel Wallach and published by Elsevier. This book was released on 2006-05-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical models are being used more and more widely to study complex dynamic systems (global weather, ecological systems, hydrological systems, nuclear reactors etc. including the specific subject of this book, crop-soil systems). The models are important aids in understanding, predicting and managing these systems. Such models are complex and imperfect. One fundamental research direction is to seek a better understanding of how these systems function, and to propose mathematical expressions embodying that understanding. However, this is not sufficient. It is also essential to have tools (often mathematical and statistical methods) to aid in developing, improving and using the models built from those equations. The book is specifically concerned with the application of methods to crop models, but much of the material is also applicable to dynamic system models in other fields. The goal of this book is to fill that gap.* State-of-the-art methods explained simply and illustrated specifically for crop models* Parameter estimation – applying statistical methods to the complex case of crop models, including Bayesian methods * Includes model evaluation, understanding and estimating prediction error* Offers a unique data assimilation by using the Kalman filter and beyond

Download or read book The Peasant Cotton Revolution in West Africa written by Thomas J. Bassett and published by Cambridge University Press. This book was released on 2006-03-30 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The literature of Africa is dominated by accounts of crisis and gloom. But Thomas Bassett, a distinguished American geographer well known in the field of development, tells an unusual story of the growth of the cotton economy of West Africa. One of the few long-running success stories in African development, change was brought about by tens of thousands of small-scale peasant farmers. While the introduction of new strains of cotton in French West Africa was in part a result of agronomic research by French scientists, supported by an unusually efficient marketing structure, this is not a case of triumphant top-down 'planification'. Employing the case of Côte d'Ivoire, Professor Bassett shows agricultural intensification to result from the cumulative effect of decades of incremental changes in farming techniques and social organization. A significant contribution to the literature, the book demonstrates the need to consider the local and temporal dimensions of agricultural innovations. It brings into question many key assumptions that have influenced development policies during the twentieth century.
Download or read book Mycorrhizal Mediation of Soil written by Nancy Collins Johnson and published by Elsevier. This book was released on 2016-11-03 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycorrhizal Mediation of Soil: Fertility, Structure, and Carbon Storage offers a better understanding of mycorrhizal mediation that will help inform earth system models and subsequently improve the accuracy of global carbon model predictions. Mycorrhizas transport tremendous quantities of plant-derived carbon below ground and are increasingly recognized for their importance in the creation, structure, and function of soils. Different global carbon models vary widely in their predictions of the dynamics of the terrestrial carbon pool, ranging from a large sink to a large source. This edited book presents a unique synthesis of the influence of environmental change on mycorrhizas across a wide range of ecosystems, as well as a clear examination of new discoveries and challenges for the future, to inform land management practices that preserve or increase below ground carbon storage. - Synthesizes the abundance of research on the influence of environmental change on mycorrhizas across a wide range of ecosystems from a variety of leading international researchers - Focuses on the specific role of mycorrhizal fungi in soil processes, with an emphasis on soil development and carbon storage, including coverage of cutting-edge methods and perspectives - Includes a chapter in each section on future avenues for further study

Book excerpt: "The potential benefits of ‘doing things more precisely’ in agriculture include terms such as environmental, economic, audit trail, vehicle guidance, crop management and others. Whilst some benefits have proved elusive, others are contributing positively to today’s agriculture. In such an environment, continuing research is required - and needs to be reported and disseminated to a wide audience. These Proceedings contain papers presented at the 5th European Conference on Precision Agriculture, held in Uppsala, Sweden. The papers reflect the wide range of disciplines that impinge on precision agriculture - technology, crop science, soil science, agronomy, information technology, decision support, remote sensing and others. Peer-reviewed papers from the 2nd European Conference on Precision Livestock Farming are presented in a companion proceedings, Precision Livestock Farming ’05."
