Disturbance amplifies sensitivity of dryland productivity to precipitation variability

Variability of the terrestrial global carbon sink is largely determined by the response of dryland productivity to annual precipitation. Despite extensive disturbance in drylands, how disturbance alters productivity-precipitation relationships remains poorly understood. Using remote-sensing to pair over 5600 km of natural gas pipeline corridors with neighboring undisturbed areas in North American drylands, we found that disturbance reduced average annual production 6-29% and caused up to a five-fold increase in the sensitivity of net primary productivity (NPP) to interannual variation in precipitation. Disturbance impacts were larger and longer-lasting at locations with higher precipitation (>450 mm mean annual precipitation). Disturbance effects on NPP dynamics were mostly explained by shifts from woody to herbaceous vegetation. Severe disturbance will amplify effects of increasing precipitation variability on NPP in drylands., , , # Disturbance amplifies sensitivity of dryland productivity to precipitation variability

## Description of the data and file structure

This dataset includes remotely sensed data acquired through Google Earth Engine. All pipeline pixels were averaged to the climate pixel level, thus each row of data corresponds to multiple Landsat pixels (30m spatial resolution) either in the pipeline corridor (pipe) or in the adjacent undisturbed vegetation, that are then averaged to the climate pixel scale (1000m spatial resolution).
