The Groundwater Harvest Potential Map is the first attempt to provide quantitative
information on sustainable rates of groundwater abstraction in South Africa on a
country-wide basis.
The single A0 Map Sheet comprises:
The main map depicts the maximum volume of groundwater that
may be abstracted per
square kilometer per annum without depleting the aquifers. Harvest Potential was
determined from groundwater recharge and groundwater storage. (Scale 1 : 3 000 000).
-
3 Inset Maps
- Factors restricting Available Harvest: (Average annual recharge, variability of
recharge, or volume of effective storage) (Scale 1 : 8 500 000)
- Mean Borehole Yields (Scale 1 : 8 500 000)
- Electrical Conductivity (Scale 1 : 8 500 000)
A concise account of the determination of Harvest Potential, the applicability of
the map, and a comparison of Harvest Potential with Exploitation Potential.
Please note: Harvest Potential gives the maximum rate at which groundwater can be
sustainably abstracted. Local socio-economic or environmental factors could reduce
this considerably. This map is intended to provide a national overview and perspective
on sustainable abstraction. It cannot be used for local planning, development or
management of groundwater. Such exercises require local investigations and assessments.
