[dataset] MapSPAM Access

This dataset is part of the MapSPAM series on spatial production. It is produced as interim result using GPW v4.0 population data as input. Based on the estimates of the rural population, this dataset shows a measure of market accessibility as the relationship between MapSPAM AggRurPop and the maximum resp. minimum rural population density within a country.

"We adopt the population count from the Gridded Population of the World (GPWv4.0) as a proxy to consider the influence of market accessibility (Access) on farmers' crop choices (Eq. 10). GPWv4.0 provides a gridded representation of human populations across the globe at a 30 arcsec resolution (CIESIN, 2016). For SPAM 2010, we aggregate the population count grid to a 5 arcmin resolution and recalculate the population density."
