# Water Exploitation Index plus (WEI+) at sub unit level, 2023

This metadata covers the vector dataset of the Water Exploitation Index Plus (WEI+) for European sub unit levels for the years 2000 to 2023, broken down into four quarters each year.
Q1: Jan., Feb., Mar.
Q2: Apr., May, Jun.
Q3: Jul., Aug., Sep.
Q4: Oc., Nov., Dec.

The Water Exploitation Index plus (WEI+) aims to illustrate pressure on renewable water resources of a defined territory (sub units) in a given period (e.g. seasonal, annual) as a consequence of water use for human activities. Values above 20 % indicate that water resources are under stress, and above 40 % indicate severe stress and a clearly unsustainable use of freshwater resources (Raskin et al., 1997). 

The downloadable data is provided in two datasets:
- Spatial data in SHP format.
- WEI+ data in Excel format, covering four quarters per year from 2000 to 2023.
The datasets can be linked via a spatial join using SHP.thematicId and Excel.spatialUnitIdentifier, ensuring the data is filtered by year and quarter.https://doi.org/10.2909/b16bd284-f2ec-4164-90b7-674c1de399ba
