Soil Fertility Decline in the Tropics
Author: Alfred E. Hartemink
Publisher: CABI
ISBN: 9780851998497
Category : Technology & Engineering
Languages : en
Pages : 380
Book Description
Wide coverage of soils and perennial cropping systems in the tropicsSynthesis of decades of researchChallenges assumptions on the benefits of plantations for soil fertilityIt is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil.This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.

Land Degradation and Society
Author: Piers Blaikie
Publisher: Routledge
ISBN: 1317411943
Category : Science
Languages : en
Pages : 323
Book Description
Why does land management so often fail to prevent soil erosion, deforestation, salination and flooding? How serious are these problems, and for whom? This book, first published in 1987, sets out to answer these questions, which are still some of the most crucial issues in development today, using an approach called ‘regional political ecology’. This approach acknowledges that the reason why land management can fail are extremely varied, and must include a thorough understanding of the changing natural resource base itself, the human response to this, and broader changes in society, of which land managers are a part. Land Degradation and Society is essential reading for all students of geography, agriculture, social sciences, development studies and related subjects.

Savanna Ecology and Management
Author: P. A. Werner
Publisher: John Wiley & Sons
ISBN: 1444314122
Category : Science
Languages : en
Pages : 234
Book Description
This volume is the fifth in a series of publications produced over the last five years on the ecology of tropical savannas. The volumes arise from work undertaken by the Responses of Savannas to Stress and Disturbance (RSSD) Program, under the auspices of the International Union of Biological Sciences (IUBS) Decade of the Tropics Programme, co-sponsored by the UNESCO Man and the Biosphere (MAB) Program. Savannas cover just under one third of the world's land surface and contain a large and rapidly growing proportion of the world's population as well as the majority of its rangelands and livestock. Most savannas are experiencing increasing pressures from demographic and economic changes that have increased dramatically over the past few decades. In addition to the changing patterns in demography and economics, and the forecasts of global warming further alert us to the most important challenge - to conserve and manage wisely the savanna ecosystems of the world. It is this conservation that forms the basis of the work of the RSSD Program. This fifth publication is comprised of research papers presented at the RSSD's international symposium held in Darwin, Australia, in 1988. The papers address the Australian perspective and intercontinental comparisons and come from an international, expert authorship.
