To determine the environmental niche of Arabica coffee, I intersected datasets using the following params:
Climate (from WorldClim V1 (Bio)):
- Annual Mean Temp (18°C - 22°C),
- Annual Precipitation (1200mm - 3000mm),
- Coldest Month Minimum (≥ 5°C),
- Driest month rainfall ≤ 120mm.
Terrain and Soil Chemistry (from USGS SRTM 30m and OpenLandMap H2O Digital Soil Mapping):
- Elevation (≥ 600m),
- Slope (2° to 30°),
- Soil pH (5.0 - 6.5)
For modelling future conditions I used the NASA NEX-GDDP-CMIP6 global dataset using a 5-year average from 2048 to 2052, using the MIR0C6 model and SSP245 pathway (middle-of-the-road emissions scenario)
Dataset processing was done in Google Earth Engine
Full disclosure: Sarkoa is my side-project I've been building for the last few months to easily host my interactive maps.
