Acknowledgements
- The achievements made so far in collecting, processing, evaluating and disseminating information and data on MPTS for the benefit of both research and development in agroforestry is not the result of efforts made by the author alone but rather that of successful teamwork.
- Without the competent inputs of ICRAF's computer programmers, Peter Muraya and Paul Waiguru, who developed the increasingly complex pro- grammes for the Multipurpose Tree and Shrub and the Seed Directory Data Bases, less progress would have been made.
- Of no less importance is the work of Harald Arnold and Gregor Wolf during the development of the MPTS information system and its various components.
- The many infor- mants in the field who have volunteered to share their knowledge with us to the benefit of those who need it cannot be acknowledged individually but their valuable contributions deserve appreciation.
- Financial support has been received from the Federal Republic of Germany through GTZ.
