The sub-Saharan Africa (SSA) region comprises 48 sovereign states. These are
grouped into five subregions, namely eastern Africa, southern Africa,
The IPGRI SSA strategy identifies
the major environmental and social trends that can influence PGR
conservation and management into the future. Some of these trends may have positive impacts on genetic diversity,
while others may have negative impacts. They therefore come with new challenges and opportunities that should
be taken into consideration in the development of plans for work in PGR
conservation and use in the region.
Effects of population growth
The high rate of population growth
in Africa is likely to continue, although at reduced rates. High populations will continue to put a
strain on food security and poverty alleviation. There will also be continuing land
clearing and deforestation that could threaten genetic diversity and lead to
species loss.
The focus on high-yielding crops to
satisfy food needs for the ever-increasing population, could also threaten
genetic diversity as indigenous crops give way to improved varieties.
Effects of climate change
Among anticipated changes, perhaps
some of the most significant are related to climate change. The global
warming and greenhouse gasses phenomena, among others, are changing the
environment in which plants and other living organisms live and grow.
Genetic resources in long-term storage in
genebanks could find a changed environment when they are finally brought
back into cultivation.
There would be increased need for
regeneration of genebank materials to ensure adequate evolutionary
transformation of the materials.
The value of in situ conservation
will be enhanced as a means of ensuring that conservation and environmental
transformation go hand in hand.
Changing climates could affect genetic
diversity in species and genepools, especially in the drier environments.
Human nutrition and health
The growing pandemic of HIV/AIDS on
the continent will negatively affect human health and labour availability
for agriculture and other jobs. The search for remedies and cures for HIV/AIDS-related conditions will continue.
The exploitation of plant genetic resources will be an integral part
in this search.
Major emphases in PGR conservation
and use will include:
Promotion of indigenous plant species with high nutritional
value, e.g. the African leafy vegetables
More emphasis on medicinal plants (including medicinal trees).
Scientific and technical environment
There are major technological
advances foreseen in the global environment. The dramatic developments in biotechnology of the past few years are
expected to influence the conservation and use of plant genetic resources,
with both positive and negative implications.
Sub-Saharan Africa is lagging behind
in most of these technological advances: biotechnology, conservation
science, and information management. There are opportunities and challenges
for PGR work in sub-Saharan Africa with respect to these technological
advances.
Institutional and political factors
A variety of institutional and
political factors and trends could influence the future of plant genetic
resources in the continent. Some of these are:
The growing significance of sub-regional organizations (SROs)
as umbrella organizations, providing guidance, support and collaboration
among national agricultural research institutions, for strengthening
agricultural research in the regions. SROs could provide potential avenues for strengthening PGR conservation in the
context of agriculture and natural resources management in respective
sub-regions.
Instability in some government policies with respect to plant
genetic resources, leading to differences across countries in genetic
resources policies and lack of fit with regional and international
discussions.
General state of insecurity, political instabilities and wars
– could destroy what has been achieved already, hinder implementation of
planned activities and also lead to change of emphasis of interventions.
Expected restructuring of the
CGIAR and the on-going
deliberations on the CG Strategy on sub-Saharan Africa could lead to changes
in collaboration and co-ordination of PGR activities within the continent.
