Zusammenfassung der Ressource
Large scale water
transfer scheme - South
Africa
- Challenge and objectives
- water resources are,
scarce and extremely
limited
- evaporation is high,
no truly large rivers
exist
- Zambezi River, is the
closest large river to
South Africa.
- poorly endowed with
groundwater
- Four of South Africa’s main
rivers are shared with
other countries, which
drain about 60% of the
country’s land area
- The use of water is dominated by irrigation
- especially vulnerable to changes in water availability
- Response
- The National Water Act gives highest priority to water
- water is allocated by
public authorities and by river
basin to ensure that the greatest
overall social and economic
benefits are achieved.
- Water resources through the country
have been linked through inter-catchment
transfers
- thereby reducing the potential
risks of failure through the
combined utilization of
resources
- move some of the water intensive and
low water efficient production to
countries with more better climate and
soils.
- possible solutions
- Demand side measures to increase water availability
- Re-allocation of water
- construction of new dams
and related infrastructure
- how the growth in water requirements can be met in future
- bring new interventions on line to meet
the growth in water requirements
- offer the lowest cost options
- Cape Town
- being more remote from large rivers
- not having the same benefits of scale of
the Johannesburg/Gauteng area
