A 4 Degrees Warmer Region: Challenges and Opportunities in the Dry Areas
Aly AbousabaaDirector General
ICARDAScience-based solutions for thriving, resilient livelihoods in the dry areas
Why Discuss a 4oC Warmer World?
• By 2100- 40% chance of exceeding 4oC - 10% chance of exceeding 5oC
(Sources: IEA, 2012; World Bank, 2014)
• 4oC warmer world could affect 70-80% of land area in MENA- rainfall could reduce as much as 60%- population is projected to double by 2050
• Crop yields will reduce drastically - wheat yield will reduce by 60% in Syria- legume and maize will be most affected crops
(Source: Schilling et al., 2012)

• High value and climate resilient crops
• Crop improvements for yield potential and for abiotic and biotic stresses
• Integrated livestock/rangelands/crops production systems
• Intensification and diversification of cropping systems
• Protected agriculture
• Improvements in water availability and management; grey water use
• Added value on dairy products in marginal dry areas

FIGS approach links adaptive traits, environments (and associated selection
pressures) with genebank accessions (e.g. landraces and crop wild relatives)
‘focuses in’ on those accessions most likely to possess trait specific
genetic variation.

Focused Identification of Germplasm Strategy
If a dependency exits between environmental parameters and the emergence of an adaptive traits within an in-situ population then we can use this relationship to
predict where adaptive traits are likely to occur elsewhere.

Farming with Alternative Pollinators (FAP)
Principle: attract wild pollinators via habitat improvement to reduce cost of farming, promote biodiversity, and increase crop yield (i.e., reduce the distance between nests and fields)
A scalable approach to protect pollinators worldwide
• Increases income significantly
• Protects wild pollinators without rewarding scheme (as in USA and EU)
• Focuses on cross-sector policy instruments for pollinator protection, which can be adopted even by Low Income Countries
ICARDA is the only CG center working on pollinator protection

Support to Agricultural Research for Africa: More Wheat for Africa
Target: 12 countries3 hubs and 9 partner countries
Agro-ecologies: 2 main types• Heat prone (lowlands)• Disease prone (highlands)
Impact:• 50 new varieties released• 4-7t ha-1 2-3 t ha-1
• Up to 400,000 ha increase in wheat surface• Up to 2 Mt production increase

Breeding trials in Marchouch, Morocco
In Northern Africa barley is commonly used for human consumption, especially in
rural and marginal areas
• Line 2Ab09-S06F084-5 identified for very high β-Glucan (15.9%)
• High Fe (54.8 ppm), Zn (37.9 ppm), and β-Glucan (>8%) varieties ‘Chifaa’ and
Assiya released in 2016 in Morocco.
Food barley for North Africa: β-Glucan and micronutrients++

Malt is used for alcoholic and non-alcoholic products, and
it receives a premium price.
Cultivation of high-input malt barley can supply new
income to smallholder farmers
Ethiopia and India have released 8 new malt-type varieties
of ICARDA origin

Conclusions
1. Genetic variability (biotic and abiotic stress) exists in Centers of Diversity and Genebanks
2. Beneficial traits are being identified through FIGS and field-based phenotyping
3. Trait introgression is done through pre-breeding/breeding and testing in key locations
4. ICARDA continues to collect agrobiodiversity and to refine algorithms for FIGS
5. For Climate Change (higher temperatures) new traits need to be identified- introgressed
