Biophysical variables

Socioeconomic variables

Agriculture production

Indicators

Similarity 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

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
