ABSTRACT
Climate change will have negative impact on plant genetic resources and its conservation. This
paper summarizes efforts made in reducing the impact of climate change on yam genetic
resources in Ghana. Strategies have been adopted to forest
all extinction of our unique yam
genetic resources through collection, distribution and conservation. To date 393 accessions of
yams have been assembled, comprising the main seven species found in Ghana. Methodologies
being used for conservation are: on
-
s
tation conservation, duplication of the accessions in
-
country in the various ecological zones,
in
-
vitro
conservation both in Ghana and outside.
Access of yam genetic resources to farmers, have been improved through multiplication and
distribution to augmen
t their genetic base. Farmer participatory selection was used to identify
and select yam accessions with unique characteristics to tolerate climate change. This forms a
holistic strategy for sustainable development of yam genetic resources, resilient to cl
imatic
change in Ghana.
Key words
: Accessibility, climate change, conservation, farmer participatory, genetic
resources, yams.
