At a glance
A constraint on water availability relative to need. At plant level it concerns crop water needs; at basin level it concerns supply, demand and access.
Why it matters
The scale and definition determine whether a signal informs irrigation, sourcing or wider water-risk planning.
An operating example
Review crop water-stress signals alongside rainfall and soil context; separately examine basin availability for a water-dependent site.
Illustrative application, not a live customer result or a guarantee of product availability.
What it does and does not tell you
A satellite vegetation-water indicator is not a direct measurement of groundwater reserves or basin water demand.
