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
Difference approaches in land stratification 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
Difference between AR and VS
