[dataset] MapSPAM Access

"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."
