FOLDER NAMES

GIS – folder containing all files used in this project with ESRI products (ArcGIS).

Current – Raster files for current climate conditions, including all files created through processing steps. Includes one folder:

bio27 – Contains all aforementioned raster files. 27 designates the grid where data were downloaded from the WorldClim website

Climate_Change – Contains five folders, one for each climate variable chosen in final population model. Climate variables were taken from 'Current' and 'HADLEY' folders and processed with Map Algebra to produce a raser of the difference between 2050 and 2005 climate pixel values.

bio02 – Three raster layers for BIOCLIM variable 02 including processed file

bio10 – Three raster layers for BIOCLIM variable 10 including processed file

bio13 – Three raster layers for BIOCLIM variable 13 including processed file

bio17 – Three raster layers for BIOCLIM variable 17 including processed file

bio19 – Three raster layers for BIOCLIM variable 19 including processed file

DEM – Digital elevation model raster files including slope

HADLEY – Contains all raster files for future climate scenarios developed by the Hadley Climate Centre using a2a forecasting. Contains two folders:

2020 – Projected climate raster layers for 2020, including all processing files

2050 – Projected climate raster layers for 2050, including all processing files

Landscape – Contains shapefiles for political boundaries and geographic features. Three folders:

Boundary – Political boundary files for Ethiopia and Africa

Lakes – Water body boundaries for Ethiopia

Woredas – State (Woreda) boundaries for Ethiopia

Population – Contains raster data for population density files including all processing steps

Tables – Output tables from random sample point data extractions
