Book Description
Agriculture is always a struggle with the environment since agricultural production is in fact applied ecology. However, in the past the struggle with the environment was to a large extent determined by the social organisation which was regionally very diverse. The aim of this volume is to find out how, when and within which structural boundaries, land was made useful for agriculture. In the first part of each chapter, this is studied in general, focusing on the evolution of land use: how and why was land reclaimed and by whom? How intensively was this land used? Which actors played a part in this process? What were the environmental and social limits? In the second part the production techniques and production systems are scrutinized: crop choices, crop rotations, the importance of fallow and cattle, crop yields etc. All this is looked at in light of different farming strategies and social conditions. The comparative approach of this volume also enables a new and innovating perspective on the occurrence and impact of 'agricultural' and 'green' revolutions in the past.

Book Description
Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Book Description
Soil physical measurements are essential for solving many natural resource management problems. This operational laboratory and field handbook provides, for the first time, a standard set of methods that are cost-effective and well suited to land resource survey. It provides: *practical guidelines on the soil physical measurements across a range of soils, climates and land uses; *straightforward descriptions for each method (including common pitfalls) that can be applied by people with a rudimentary knowledge of soil physics, and *guidelines on the interpretation of results and integration with land resource assessment. Soil Physical Measurement And Interpretation for Land Evaluation begins with an introduction to land evaluation and then outlines procedures for field sampling. Twenty detailed chapters cover pore space relations, water retention, hydraulic conductivity, water table depth, dispersion, aggregation, particle size, shrinkage, Atterburg limits and strength. The book includes procedures for estimating soil physical properties from more readily available data and shows how soil physical data can be integrated into land planning and management decisions.

Book Description
This book presents recent estimates on the rate of change of major land classes. Aggregated globally, multiple impacts of local land changes are shown to significantly affect central aspects of Earth System functioning. The book offers innovative developments and applications in the fields of modeling and scenario construction. Conclusions are also drawn about the most pressing implications for the design of appropriate intervention policies.
