2. Current Stratification process
 Biophysical variables
Rainfall (1km, 5km, 50km)
Temperature (1km)
Elevation (90m)
Slope (1km)
Length of growth period (5km,
10km)
Land cover (30m, 300m, 1km)
Farming systems
Ago-Ecological zones (1km)
Targeted crop distribution
(10km)
 Socioeconomic variables
Travel time to major market (1km)
Population density (100m, 1km)
 Household variables
Crop types
Cropping system
Individual crop share
Livestock type and density
 Expertise knowledge and regional
database
 Weather station

3. Ghana and Mali
• Cropping systems
• Length of growth
period
• Market access

4. Tanzania
• Elevation
• Rainfall

5. Malawi
•
•
•
•
Weather station data
Elevation
Temperature
Distance between the sites

6. Ethiopia
• Elevation
• Rainfall
• Slope

7. Similarity between AR and VS
 Target countries (Ghana, Tanzania, Ethiopia)
 Both adopt LSMS instruments and modules
 Soil sampling (nutrients, PH)
 Biophysical variables
 Socioeconomic variables
 Agriculture production
 Indicators

8. Difference approaches in land
stratification between AR and VS
 Vital Signs:
 4 Tiers: from coarse to fine spatial resolution.
Tier 1: Continental and regional satellite products
Tier 2: Quick ground choosing plot + existing HH
Tier 3: Water station
Tier 4: Very high resolution imageries + HH
 Africa Rising:
 Land cover is considered but does not play a key role
 Using best available and reliable biophysical and socioeconomic
variables
 HH and communities

9. Difference between AR and VS
 Utilization of satellite products on land
monitoring
Adopting existing land cover product (1 tier)
Groundtruthing on crop types on the ground
Develop project oriented land cover and land use
product at at multi scale
Monitoring changes and evaluating impacts using very
high resolution images
Feature extraction and identify the homogeneous units
Scale up

10. Knowing land cover /cropping
system pattern is important
 Climate forcing
 Wood fuels
 Livestock's
 Water security
 Monitoring
 Scale up
 Validation
 Sustainable Agricultural
Intensification
 Soil health
 Resilience
 Biodiversity

11. Difference between AR and VS
 Ecosystem services
 Developing biodiversity security indicators
 Water security

12. Collaborations
 Field sampling
 Household survey
 Spatial coverage
 Ghana?
