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. Matched by basin, by month and by hundred meter height band,
so those three are not carrying the difference. Soil, slope and what
is grown on the cleared ground are not matched, so this is a
comparison and not the effect of clearing.
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: across the basins
holding both kinds of ground, the cleared half sits a median of 52
meters below the forest, and in these basins lower ground reads drier
whatever grows on it, at 0.021 kPa per 100 meters. Matching inside
height bands takes that gradient out - 0.002 kPa per 100 meters is
left - and halves the average difference.
What is left is small: at level 5 in the dry season
the median basin reads +0.001 kPa, and 72 of every 100 fall within
0.05 of zero. Read that as not detected rather than not there. The
humidity behind this product comes from a quarter degree reanalysis,
so the two classes inside a basin usually share one humidity value and
differ mainly in temperature: the warming half of clearing is resolved
here and the drying half is not.
