[dataset] MapSPAM AggRurPop

"For SPAM 2010, we aggregate the population count grid to a 5 arcmin resolution and recalculate the population density. Then we derive rural population density (AggRurPopi) based on the assumption that if there is cropland within the 5 arcmin grids, then the population residing within the grids should be rural people. We do not aim to distinguish rural area from urban area. Instead, the variable AggRurPopi is introduced to estimate the market accessibility and to account for subsistence production." "a. Instead, the variable AggRurPop is introduced to estimate the market accessibility and to account for subsistence production. Therefore, it does not mean the accessibility of getting food" Yu, Qiangyi; You, Liangzhi; Wood-Sichra, Ulrike; Ru, Yating; Joglekar, Alison K. B.; Fritz, Steffen et al.
