•Low and variable production

•Dry land agriculture

•Low precipitation

•High climate variability

•Drought damage

•High pop increase

CENTER REGION

• Low and variable production

• High pop increase

• Dry land agriculture

• Low precipitation

• High evaporation water deficit

• High RR var. (30mm, 215mm)

• Drough may occure in 1 year out of 3 or out of 4.

• High irrigated production

• Extreme urban water and land use conflicts

ns Project

Water resources management

- Changing system of water delivery and control

- Provide farmers with guidance on crop water management

- Provide incentives to avoid excessive water use- Water mobilization- Use of new water resources (Waste water, geothermal water, saline water, drainage water…)- Increasing water use efficiency- Etc………………

Adaptation policies I

Agriculture management

- Crop liberalization (Egypt)- Selection of cultivars(Egypt, Tunisia, Morocco)- Planting date (Egypt, Tunisia, Morocco)- Soil mulch- Inter-cropping (Egypt, Tunisia, Morocco)- Increasing of agriculture area (Tunisia and Morocco)- Use of new techniques - etc…………………

North Africa AIACC Project Outcomes

What components of the farming system are particularly vulnerable, and may thus require special attention? – CROP MODELS (e.g., DSSAT)

Can the water/irrigation systems meet the stress of changes in water supply/demand? – IRRIGATION MODELS (e.g., CROPWAT)

Will climate significantly affect national agriculture? – MODEL INTEGRATION; GIS INTEGRATION (e.g., DERIVING RESPONSE FUNCTIONS)

MODELS: Defining key questions

We have to be very careful with using model in our region because of the high variability (climate, soil, farmers behaviors…)
