25 % of runoff from cropland collected and used during dry-spells (water harvesting) and 25 % of soil evaporation from cropland avoided to increase plant transpiration (vapour shift). Simulation done for recent climatic conditions (1971–2000 average) and distribution of cropland and crop types as of 2000. Based on the LPJmL vegetation and water balance model using the ensemble mean from 21 General Circulation Models (GCMs) that were part of the 4th IPCC Assessment (Randall et al., 2007).
