Spatial frame work and land characterizing in Africa RISING and Vital Signs
1. Spatial frame work and land characterizing in
Africa RISING and Vital Signs
Zhe Guo, IFPRI
Africa RISING–CSISA Joint Monitoring and Evaluation Meeting,
Addis Ababa, Ethiopia, 11-13 November 2013
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
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
