BIO-PROSPECTING PRUNUS
AFRICANA IN UGANDA
By

National Forestry Resources Research Institute
(NaFORRI),
UGANDA
Background
• Bio-prospecting? Or Collaborative Research?
• Prunus africana – African medicinal plant, widely
distributed – wide variations genetically &
chemically.
• Commercial extraction & Export of bark a threat
• Long term survival lies in successful plantations
• Diverse plantations – higher chances of survival and
market satisfaction
Background …
Project:
DEVELOPMENT OF STRATEGIES FOR THE
CONSERVATION AND SUSTAINABLE USE OF
P. AFRICANA TO IMPROVE THE
LIVELIHOODS OF SMALL-SCALE FARMERS
Coverage: Some countries in Eastern, Central
and Southern Africa (eg. Cameroon, South
Africa, Uganda, Tanzania, Madagascar, Kenya,
Tanzania etc)
Partners involved
Project objectives
• Improve incomes and livelihoods of rural
communities – improved germplasm
• Support national and trans-boundary in-
situ and ex-situ conservation strategies –
establishment of gene reserves
• Strengthen capacities of nationals for mgt
of forest genetic resources
Location of sample areas- Uganda
Why the bother
• Debarking taking place for bio-prospecting in
different places, Africa-wide
Why the bother …

Highlights of the MTA
• Type of Agreement - Material Transfer
Agreement – (in line with Ugandan law)
• Type and quantity of resource(s) - Prunus
africana bark (for Chemical analysis) and leaves
(for genetic analysis); Small quantities for
research/ analysis – (In Austria)
• Purpose of collection and expected results –
Research; results to be returned for use in
mother garden (Gene reserves) establishment
Highlights …
• Location of research and development
• a)Partly in Provider country (collection,
multiplication and scaling out/ planting)
and
b) Partly in User country (Chemical and
genetic analysis – samples from different
participating countries)
