For benefits to accrue to the global community, an extremely
cost-effective way is to take two complimentary approaches to better
understanding and managing water quality issues in a changing climate. Most
decisions regarding the status of natural resources (such as water quality) and
the potential or actual impact on these resources by proposed management
actions are underpinned by measurements of specific parameters that are seen as
“indicators” of the health of the asset. However, while indicators such as
these are highly variable in both space and time, the measurement and ongoing monitoring
of these indicators are inherently limited in both of these aspects due to
resource constraints in terms of time, money, people and equipment.
Studies have been completed previously which illustrate
the importance of the appropriate temporal frequency and spatial distribution
of monitoring networks. It is clear from these studies that monitoring at too
small a frequency or area distribution can significantly misrepresent the true
magnitude and effect of complex processes such as catchments-scale contaminant
loss.19 Implementation of monitoring equipment and schedules at the appropriate
rates and densities to provide truly meaningful data and the use of
conventional monitoring equipment can cost many thousands of dollars per year. However,
by adopting a two pronged approach that seeks to understand the dynamics of
climate inputs – rainfall in particular – and the causal effects of redistribution
of water in the landscape, it is possible to achieve sustainable outcomes.
The primary outcome of this development is a decision support
toolkit that will inform investment, adaptation, resource condition assessment,
and land and water management. This toolkit will provide land and water managers
and key decision makers with an effective methodology for improved
understanding of short-tome dium term rainfall variability and climate change
by: facilitating best management practice for land, water and productivity in
marginal and dry land agriculture; facilitating improved rural water supply
systems; optimizing opportunities for sustainable management of ecosystems such
as rivers and landscapes and the productive resource base; providing data for
improved water resource management, water policy instruments and government
response; analysis of the effect of rainfall variability on water run-off,
groundwater recharge, water quality, soil condition, nutrient status and
nutrient cycling under current and potential land uses in the soil-landscapes
of SWA and a selected North American region; and high frequency data collection
undertaken to measure the temporal scale of these fluxes and, especially, the residence time of water and contaminantsunder a variety of weather and climatic conditions.
