Rainfall by isohyets according to data from representative stations
NB: the sample is very small which results in anomalies; in addition, isohyets create artifical boundaries. The data need to be smoothed to correspond better to the real world.

Rainfall, m3/ha, final smoothing
The input grid of rainfall is resampled to 1km2. It is then smoothed with a radius of10. Then, it is resampled back to 100m and cropped with the island coastline.

Evapo-Transpiration: from the MODIS16A3 product to the ETP map
The MODIS16A3 product contains ET values in 0.1mm, the cells being of 1km2. It is reprojected from sinusoidal to UTM, then resampled to 100 and truncated at 16000 to eliminate artefacts due to the clipping out of sea and artificial surfaces in the algorithm. A second adjustment for artificial areas is done (ET/(M01/10). The result is then smoothed (Gaussian filter, radius 10).

Water Intensity of Use
The Water Intensity of Use Index is the ratio between Accessible Resource and Total Abstraction of Water. These results are experimental and request further validation and completion as well as clarification regarding dams.
The map reads that values below 100 reflect a structural deficit (which is clearly the case in the northern catchment for the need of which has been created the Midlands reservoir.
Values between 100 and 120 seem reflecting some vulnerability to climate variations and / or a dependency from external supply.
Catchments beyond 150 are in excedent.
