Showing major results, challenges and threats of climate. Explainnig proposed solution by Bioversity International. In particular, we investigate on the role of durum wheat genetic diversity to provide options to manage climate related risks and adaptation options to climate change. The solution proposed is tested against food security and climate change

Understanding the role of genetic diversity to manage climate risks in Ethiopia

manage climate risks

9. Food security issues
• More than 200 million people in Africa, or
23% of the people, suffers from hunger, and
despite declines experienced in the past six
years
• About 40% of children under the age of five
in sub-Saharan Africa (SSA) are
underdeveloped due to malnutrition (IIED
data)

Climate analogues between evaluation sites
12. -Don’t overestimate importance of climate analogues
-Introduced material from very different climates can
perform unexpectedly well (examples of potato, pea, and
barley varieties from warmer to cold climate )
-Importance of photoperiod (accessions collected in the
same latitudinal zone have most potential)
-Importance of quarantine system for newly introduced
material (prevent exchange of pest and diseases)

The need for agricultural biodiversity
The heavy reliance on a narrow diversity of crops puts future
food and nutrition security at risk.

14. • Genetic diversity refers to the
total number of genetic
characteristics in the genetic
makeup of a species.
• Foundation of all
improvements
• Used by generations of
farmers
• Source of traits for:
• Increased productivity
• Resistance to biotic and
abiotic stresses

Outcomes
Empowerment of communities: more
resilient to eco-socio-economic changes,
more resilient food systems
Outcome
Preservation of options
for resilient systems
Outcome
Self-reliance of value chain
actors on broader set of
options, making them more
resilient to market changes.

enabling farmers
to adapt to change
27. • Is a rapid approach to identify crop varieties
adapted to changing climates and markets
• Uses existing diversity
• Can be customized to local and marginal
conditions around the world
• Directly responds to farmers’ needs
