Understand the social and economic impacts of new public policy at community, regional, Basin, State and National levels.
Communicate these impacts using common metrics and analysis at these scales.
Best available scientific knowledge and socio-economic analysis (Water Act 2007).Data ChallengesDisaggregate national and state economic data to better understand community and regional contributions.
Aggregate local social data to State, Basin and National impacts.
Effort to re-aggregate existing data for a non-standard geography (to ABS) that was still under development (by MDBA).
Evolution of boundaries impeding time-series analysis.
Increasing number of boundaries CSIRO, Natural Resource Management (CMAs), water catchments, Basin Plan regions, ABS geography.
Data ChallengesABARE AusRegion MDB regions (comparison with WTM regions)11Best Available agricultural and population data relates to 2005-06.
Much of the exiting analysis and underlying data for models relates to 2006 or 2001.
Challenging to look forward to what might happen when data could already be considered old.
For example, the drought has reportedly changed the face of much of rural Australia in the last 5 years but the data wont reflect this, as yet. The currency of data High expectations of social and economic data.
Economic data and modelling is designed for national and State purposes but we need to understand the flow on to local and regional areas.
As we extend the use of data at what point are we left with assumptions and no data.
Yet it is increasingly important to more fully understand a local areas contribution to the national wealth.
Concern that once local area data is aggregated the human dimension is lost.
Data issues13Took advice early ABS and ABARE were two of the first agencies contacted.
Allowed the ABS to do what they do best producing the Context statistical report for the Basin (with ABARE and BRS).
Sought regular ongoing advice on developing the short and long term data needs for the Basin plan.
An active dialogue with the ABS (and others) to progress the issues raised.How did we progress?The FutureStrengthening strategic alliances to improve statistical data in the Basin.
Defining data needs early to meet future requirements (Monitoring and Evaluation).
Better using opportunities (Agricultural Census, Agricultural Survey).
Identifying less obvious opportunities (cross agency agreed priorities, question design).
