Research Portfolio for 2008/2009
The projects contributing to the thrusts for this
Impact Area are implemented and managed by the
different Water KSAs. Project details are included in
the individual KSA lists.

Thrust 1: The Role of Water
in Economic Development |
|
The ever-mounting scarcity of freshwater in South
Africa within the context of an expanding economy
and, thus, increasing demand will need informed
choices on water allocation between competing
needs. In general, there are two general choices
to address this problem; either increase supply or
reduce demand.
· With
a renewed focus on public infrastructure
development in South Africa the question needs to
be answered what the best possible economic
allocation of scarce resources to, or costs and
benefits of alternative shorter and longer term
water management options are, including enhancing
supply and managing demand. Such analysis must
also assist decision-makers to determine and
communicate the trade-offs resulting from water
allocation decisions.
· A
second and related question is whether South
Africa’s water resources are sufficient to support
planned economic developments (such as those
proposed in the ASGISA document), and what the
sensitivity of such economic development plans are
to changing assurances of supply, changing water
prices and implementation of water conservation
regulations and technologies. This would need an
analysis whether water, as a specific resource, is
a constraining factor in economic development in
the first place.
· A
third question is the role of water specifically
in the alleviation of poverty. Although the WRC
has a separate research programme on Water and
Society, specific issues remain that are relevant
to this Impact Area. One example is what the
impacts of water redistribution are on economic
growth as well as on broad-based black economic
empowerment, two key objectives of Government
policy. Another example is an evaluation of the
economic viability of emerging and small business
in the water sector, such as small farmers and
contractors.
· A
fourth question in this key strategic focus area
is to evaluate the economics of water service
delivery, including water supply and sanitation,
and to identify institutional bottlenecks
hampering service delivery. |

Thrust 2: Using Economic
Instruments in the Management of Water |
|
The next key element of the strategic framework is
the question of how to apply economic instruments
in the management of water.
· The
first question is at what (volumetric) levels
water prices should be set and how sensitive water
demand is to changes in water prices, moving
beyond single-point estimates on water valuation
(elasticity). Prices and demand will have to be
studied at various stages of the water supply
chain and to different users, and need to test the
affordability to water users throughout the
chain.
· The
second question is that non-market valuation
techniques need to be applied to estimate the
demand for those water-related ecosystems goods
and services not traded in markets. Estimating
the benefits of healthy water-related ecosystems
and applying these to estimate the economics of
the ecological Reserve are two topics in need of
further research.
· A
third question is what the benefits of clean water
and the cost of addressing polluted water are. To
achieve levels of water pollution that do not
cause long-term damage, while leaving space for
development; research on the damage costs and unit
control costs for key pollutants and key polluting
sectors is needed.
· The
fourth question is focused on the prerequisites
for efficient water allocation, specifically the
accurate and cost-effective measurement of water
use as well as the institutional economics of
water rights and licences.
· The
fifth question revolves around an economic
evaluation of water policies and the application
of economic policy instruments to water
management. A regulatory impact assessment on the
National Water Act is proposed, as well as
practically focused research on the feasibility of
water markets and (waste) water charges.
· Finally,
the question of how the results of economic
analysis can better be integrated in the policy
making process, needs specific research. |

Thrust 3: Dealing with
Complex Water-Economy Systems |
|
The causal relationships within complex
water-economy systems need to be explicitly
recognised and their sensitivity to biophysical
and socio-economic change tested. Cause-effect
relationships on larger-scale complex systems such
as catchments are not necessarily obvious. Water
needs to be managed for multiple uses in a
sustainable manner. Integrated assessment and
multidisciplinary modelling approaches are needed
to provide a systems-wide perspective on the
management of water resources. The sensitivity of
socio-economic activities and the value associated
with these activities need to be tested for the
impacts of extreme events and gradual changes.
Integrated water-economic modelling on a catchment
level is needed to inform appropriate catchment
management strategies. |
