The book 'Some Medicinal Trees and Shrubs of Eastern Africa for Sustainable Utilisation and Commercialisation' is a fulfilment of one of the major recommendations adopted by the East and Central Africa Regional Agricultural Forum for Training Team (ECA-RAFT) Workshop and General meeting held in Kigali, Rwanda, during the period 24th — 281h May 2004. The ECA — RAFT, an ICRAF supported initiative, is a regional network of public Universities and Colleges, dedicated to the enhancement of training in Agroforestry and integrated natural resources management in tertiary institutions. The general assembly of ECA—RAFT, while reviewing the status of Agroforestry and natural resources educational materials available in universities and tertiary institutions in the region, concluded that there was an urgent need to enhance and mobilise the teaching capacity of educators and educational institutions in Agroforestry and integrated natural resources management. Hence, the adoption of the recommendation: andldquoto develop a new manuscript on medicinal trees and shrubsandrdquoas one key regional priority activity in pursuit of this objective. Consequently and within the constraints of the available resources, a regional team drawn from four universities namely, Makerere University, Jomo Kenyatta University of Agriculture and Technology (JKUAT), Kenyatta University (KU) and coordinated by Maseno University (MSU) was constituted to undertake the task that has culminated in the publication of this book.
