Sustainability of shared freshwater resources in the South Africa

Dialogue on Water Governance 2015 , Fortaleza, Brazil, November 2015

Water in South Africa and SADC

• Water is a scarce resource.

• Mean annual precipitation is about 500 mm

• The Eastern and South parts of the country receive more rainfall.

• Water quality worsen our H2O challenges.

A drought prone region

Observed and simulated datasets were used

Other Challenges• Like many developing nations, SA has to strike a

balance between water resource use and protection.

• In pursuit of its development agenda, the country has encountered several water challenges.

• The most concern of them all is water (Quality, .... which cannot be separated from Quantity in South Africa)

• What use to bring certain kind of relief as solution…… are now of little use!

How much is enough – policies?

• The departs responsible with water and environment developed several policies aimed at challenges relating to water and the env.

• The main ones are National Water Act (NWA), National Environmental Management Act (NEMA), National Water Service Act.

• How many more should we have? How many amendments do we need?

• We always say, everybody “lives downstream”, -Water management should be focused on the whole catchment/basin.

• We look at policies for guidance to abate water and env. problems. …….. is it where the solutions are?

• We always say, everybody “lives downstream”, -Water management should be focused on the whole catchment/basin.

• We look at policies for guidance to abate water and env. problems. …….. is it where the solutions are?

We have unequal society (in socio-economic terms), which compels decision makers to be pro- poor and the voiceless.

Olifants WMA as a case study area

Olifants

The Olifants Water Management Area• The Olifants WMA has a surface area of

approximately 54 550 km2. • Comprised of secondary catchments with

significant variations in climate, water availability, level and nature of economic development, and population density.

Land Cover/ Use

• The major land uses are, agriculture, afforestation, livestock and game farming, and mining.

• The eastern portion of the catchment is under conservation (KNP).

Conditions of Water Resources

Mostly:•Reduced Flows / over-abstraction (quantity)•Pollution (quality)

Water requirements in the Olifants WMA

Quantity & Reconciliation

This overall water resources situation shows that the catchment is in deficit of 192 M m3/a

The Reserve and Water Use licensing

Water quality is a neglected part of the Reserve

• The declining water quality in the Olifants WMA is related to:– Acid-mine drainage, – Increased mining activity in the upper

catchment,– Poor waste-water and sewerage treatment

plants.

• People, industries, and the ecosystems are negatively impacted by poor water quality

The rainfall datasets are needed for planning and proper management of water resources

• We used to have >2000 stations.

• Currently, we have less than 700 stations.

• We need to revamp our monitoring networks

Conclusions• We need to stop to approach natural resources

management from a single-domain perspective. • Poorly implemented Policies and Strategies

(although attractive) are as good as not having them.

• Investment in R&D and capacity building is insufficient.

• Partnership with the regional and global community is a necessity.
