Book Description
Shifting cultivation is the predominant system of arable farming in the humid and sub-humid tropics, where several hundred million people depend on this system of agriculture for their livelihood. This book documents and systematizes findings in shifting cultivation from over the last six decades, including characterizing secondary succession and relating the changes that fallow vegetation undergoes to the process of soil fertility restoration. This book is essential reading for researchers and students of tropical agriculture and related areas.

Book Description
Providing a snapshot of CTA’s achievements during the last decade, this book is a celebration, rather than a conventional impact assessment. Under six broad chapter headings – producer organisations, policy action, ICTs, research and development, providing information to farmers, and trade and markets – it gives a fascinating insight into the broad range of activities that CTA has supported through partnerships across Africa, the Caribbean and the Pacific (ACP).

Book Description
This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.
