Analyzing precipitationsheds to understand the vulnerability of rainfall dependent regions

Concept of precipitationsheds, defined as the upwind atmosphere and surface that contributes evaporation to a specific location’s precipitation.:

We illustrate the importance of upwind land cover in precipitationsheds to sustain precipitation in critically water stressed downwind areas, specifically dryland agricultural areas. […] This work demonstrates that seemingly separate parts of Earth’s biophysical system are interlinked with its social systems. Indeed, our results and analysis suggest that food security in some of the world’s most water-constrained rainfed agricultural regions could be very sensitive to distant land cover changes.
