Much of this book is concerned with agricultural change, involving a certain amount of historical reconstruction. It is important to set doctrinal assumptions aside and, in particular, not to assume without evidence the existence of any process such as degradation or intensification. Change can take many forms, and the adoption of practices that are more intensive in use of capital or labor is only one form. Comparatively, it is useful to describe one system as more intensive than another, but the terms to intensify and intensification are used loosely in the literature. I introduce the theory of intensification in chapter 4 but discuss it in some depth only chapter 11. Elsewhere in the book, I avoid these terms as far as possible. Certain other themes are also of major significance.
