  • Updated description of MapSPAM IrrArea from

    "We adopt the irrigated area (IrrArea) from the Global Map of Irrigation Areas (GMIA) to consider the share of irrigated area within a grid as an allocation parameter. GMIAv5.0 is the only irrigated area dataset with global coverage, which estimates the amount of area equipped for irrigation at a 5 arcmin resolution for the period around 2005 (Siebert et al., 2013). GIMAv5.0 does not include information on the functionality or quality of irrigation equipment and makes no distinctions between different types of irrigation, which may introduce errors and inconsistencies into the allocation." <br> *Yu, Qiangyi; You, Liangzhi; Wood-Sichra, Ulrike; Ru, Yating; Joglekar, Alison K.

    This dataset is part of the MapSPAM series on spatial production. It is produced as interim result using GMIA v5.0 data about irrigated areas as input.
