[process] MapSPAM Adopt Irrigated Area

This process is part of the MapSPAM series on spatial production. It is created as an interim process using the listed datasets below. In this process, all irrigated areas from the GMIA Map are selected and stored in a grid.

"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."
