Section 3 Data Codebook

All results are available in STATA format on Huddle. The next section shows summary statistics for a sample of indicators.

STATA files are organized by country, by source, and by periodicity:

  • 2017-agresults-{ISO3}-biovars.dta
    1970-2000 baseline bioclimatic indicators (source: WorldClim), altitude and slope (source: SRTM)
  • 2017-agresults-{ISO3}-traveltime.dta
    travel time to nearest market (5 market sizes) (source: IFPRI/HarvestChoice)
  • 2017-agresults-{ISO3}-soil.dta
    soil organic carbon content and most probable soil class (source: SoilGrids)
  • 2017-agresults-{ISO3}-monthly.dta
    2015-2017 monthly bioclimatic indicators (source: FEWSNET/USGS/MODIS)
  • 2017-agresults-{ISO3}-dekadal.dta
    2015-2017 dekadal bioclimatic indicators (source: FEWSNET/USGS/MODIS)

All extracted indicators are listed below. A complete codebook is on Huddle.
