Available Water Resources

Amount of sub-surface water available uncertain – limited due to geology

Only 1 natural lake

Wetlands – but lost more than 50%

Over abstraction e.g. Limpopo River sometimes doesn’t reach Kruger National Park

Do Inter-basin Transfers meet demands?

High demands for industry & agriculture (BEE)

Growing urban populations

Building dams affects river output – affects water supply to other areas

Traditional African Value of WaterKhoisan & San lived in arid areas but moved with rainfall patterns

In African cultures river gods and rituals linked with water

Cultural & spiritual value –maintain society’s life blood

Some, For All, Forever!

Water Services Act 1997 & National Water Act 1998 – free basic water

Recognises water is a scarce resource, unevenly distributed

Aims to manage what water there is as efficiently as possible


Human needEnvironmental need The Reserve

Buffer for future use

“The Water Reserve” Principle

The Reserve = water always there to meet basic human & ecological needs

Surplus to beallocated to other uses


Key Challenges & Priorities

Implementing the Water Act

Balancing environmental protection with water provision for development

Issues of co-management


Uncertainties & Risks for the Future

Population Growth– Current Population: 48 million– Population Growth Rate: 0.48%

Urbanisation

Climate Change

Impacts of Climate Change

Temperature increases: 1°C to 4°C by 2050

Broad reduction of rainfall (5% to 10%)

Longer dry spells followed by intense storms.

Severe impacts on freshwater resources.

Recommendations & Proposals

Better use of existing water– Stricter demand management

techniques– Reallocation to most profitable

sectors – Monitoring water quality & bio-

remediation– Optimal usage of water

Investigating alternative water resources
