how much of the land supplying the basin lies
in a cell that lost forest, 2001–2025
The two views above multiply this by how much of the
basin's rain comes from land at all. This is the deforestation of the
rainshed on its own, so a basin reads pale either because its
rainshed is intact or, above, because little of its rain came from
land in the first place.

This is one dimension of water risk exposure, not
all. This is deforestation risk of land-based precipitationsheds.
For example, India reads as orange with many people and croplands and
little of its precipitationshed impacted by forest loss. However, much of the North
is severely water stressed.

Inside one basin: how thirsty the air is over the
land that lost its forest, minus the same over the land that still
has it. Red, the cleared side is drier; blue, it is
damper. Same basin, same months and same hundred meter height band,
so season and terrain cancel and cover is what is left.
not enough of one class to compare
Thirst here is vapor pressure deficit, in
kilopascals: how much more water the air could hold before it is
full. The higher it runs, the harder it pulls water out of leaves and
soil.
Clearing takes the low ground, and air is drier
downhill whatever grows on it: cleared land sits a median of 52 meters
below the forest it is matched against. Comparing inside height bands
removes four fifths of that. What is left is small, and it is mostly
the air running warmer rather than holding less water - the humidity
behind this product comes from a quarter degree reanalysis, too coarse
to see a clearing.
