Dialogue on Water, Energy and Climate Change
(WECC)
Report from the Australian Dialogue and Preparatory
Meeting for 5th World Water Forum, Istanbul, Turkey,
held in conjunction with International
RiverSymposium, Brisbane, Australia
Greg Claydon, Executive Director, Queensland Department of
Natural Resources and Water, Australia
Torkil Jønch-Clausen, Director, DHI Water Policy, Denmark
Features of the Australian Dialogue
•
Aims
1. establish greater Australian ownership of the vital issue of links between
climate change, energy and water, and provide an Australian forum to
discuss Australia's policy options and actions
2. provide initial responses from the meeting to inform the 5th World Water
Forum in Turkey, March 2009
•
Presentations by
- DHI Water Policy, Denmark and Australia
- World Water Council
- National Water Commission, Australia
- Australian Water Association
- Australian National University
- Queensland Government, Department of Natural Resources and Water
- CSIRO Land and Water
- University of Technology, Sydney

Dialogue facilitated and summarised by DHI Water Policy, Denmark and
Australia
Mid-range climate change scenario for QLD:
– An increase in daily average temperature by 2030 ~ 0.9
°C in coastal areas & 1.1 °C inland;
– Less rainfall & runoff, with regional exceptions;
– More severe droughts;
– Increase in extreme daily rainfall;
– Rise in sea-level ;
– More intense tropical cyclones; &
– Increased risk of storm surge.

WECC Draft Principles for Action
• Undertake “whole of water cycle” and “whole of energy cycle”
analysis, including use, to identify least cost outcomes and
overcome fragmentation of the water and energy cycles
• Consider climate change scenarios in water resource
planning, including the assessment of water availability and
use for environmental and human purposes
• Improve monitoring, reporting and incentives for energy
management including decentralised systems
• Consider climate variability & climate change scenarios in
water supply planning options to achieve agreed levels of
service
WECC Draft Principles for Action
• Consider impacts on the regional water balance in energy
planning options
• Consider water demands and associated climate change
implications in energy supply options
• Consider energy demands and associated climate change
implications in water supply options
• Clarify “urban system” energy use/GHG emissions to help
establish a consistent and quantitative analysis framework
WECC Draft Principles for Action
• Minimise GHG emissions by maximising efficiency of water &
energy use, use of low emission or renewable alternatives
• Consider water entitlement issues and the environmental flow
impacts in GHG policies
• Unite and encourage water-related energy / GHG research
efforts which have already commenced e.g. through a coordinated program of national efforts
Australian call for action
National policy responses in Australia can include:
• Preparation of specific directives to the Council of Australian
Government [COAG]. These could be led by one of the member
states’ natural resources agencies, using the above draft
WECC Principles for Action
• An Australian Dialogue meeting in early 2009 on national
strategic directions, supported by a Ministerial Meeting to agree
on actions
• A national study, starting immediately, to identify energy and
water footprints, their relationships, and identification of national
standards and benchmarks, cognisant of the draft WECC
Principles for Action above and similar studies undertaken in
USA, Western Europe, Singapore and elsewhere.
