The production of any ethnobiological work involves an enormous number of people. A few of those involved in the production of this book are mentioned here, but all those who are not should feel that their role was also important and is appreciated.
Work of the Indigenous Food Plants Programme (IFPP) which led to this book would not have been possible without the generous grant from the Ford Foundation for which we are deeply grateful. In this connection special thanks go to Dianne Rocheleau and Eric Rusten, Program Officers at the Ford Foundation's Eastern and Southern Africa Office in Nairobi, for their great interest and encouragement throughout the IFPP period.
We are grateful to the Canadian Organization for Development through Education (CODE) for providing funds through their Eastern Africa Regional Office in Dar-es-Salaam for production education and extension materials. In this Scott Walter, and later Julie Holder, were very helpful. In addition, the programme received seed money from Nog Meer Binding Foundation and Columbine Foundation of the Netherlands.
We are grateful to Richard L. Leakey former Director and later Mohamed Isahakia Director National Museums of Kenya for their encouragement given to IFPP.
In nutritional research, we are indebted to S. Mbugua and J. Imungi of the Department of Food Science, University of Nairobi for their support and permission to use laboratory facilities for food-value analyses.
Of particular mention and appreciation is the contribution made by the management and staff of IFPP in implementing the programme: Moses Mbugua, Secretary General, Kenya Freedom From Hunger Council (KFFHC); Grace Kanyua, Director, Worldview International Foundation Kenya (WIF); Joe Kuhn who initiated the programme and worked tirelessly to get it off the ground; Matthijs de Vreede who assisted in the programme design and continued to provide advice; David Lowe and later Bernard Muchiri, Coordinators; Abbey Olendi, Nutritionist; Gatonye Gathura, Communications officer; Jane Makumi, Programme Secretary; Nicholas Maina, Driver; and the late Peter Olala, Gardener.
The success of IFPP depended highly on local leaders and committed field collaborators who took the programme as their own, and to the local communities contained in this book and to whom much of it belongs. We are deeply indebted to them all.
