This is the first comprehensive study of Hadendowa Beja pastoralism in Sinkat Province, Eastern Suda. The book discusses the effects of the drought in the 1980s and shows the strategies for survival and for pastoral rehabilitation. The various chapters deal with the effects of drought and of human activities on the natural environment; how pastoral migration patterns were affected and how links to commodity and labour markets aggravated the effects of drought; socio-cultural changes are dealt with as well, following increased interaction between regional populations. The final chapter discusses planning problems in the region and argues that in areas such as the Red Sea Hills, the recurrent pastoral disasters cannot be blamed only on the pastoralists and their activities, but must be related to wider economic and political contexts, in which the pastoral groups are becoming increasingly marginalised. The book is based on material from the Red Sea Area Programme, a joint research venture between the universities of Khartoum and Bergen.

This book is a reprint of the fourth edition, published in 1989, of the Textbook of Pollen Analysis and is unique in its approach as it discusses both the practical and theoretical aspects of palynology. It uses palynological techniques as tools for solving problems in quaternary geology, ecology and archeology. This edition of this standard reference has the same objectives as the earlier ones but the objectives have been widened, particularly the archaeological. There are over 130 illustrations and the identification keys have been thoroughly revised and are now illustrated. "Will certainly benefit all in understanding the principles of pollen analysis. All students, palynologists and libraries should have it as a text book for reference." Marine Geology "Classic and much-used text book ... will remain an indispensable book for those interested in paleoecology and practicing pollen analysis." The New Phycologist "Unsurpassed in its restriction to basic principles, breadth of coverage, clarity of expression and emphasis on ecology." Review of Paleobotany and Palynology
