The value of water to Namoi Catchment

Modelling the economic impacts of a drier future

This report presents the results of Deloitte Access Economics’ modelling of the economic impacts of a drier future on the Namoi economy.

Over the coming decades the Namoi Catchment’s economy is expected to be impacted by both the effects of climate change and a reduction in irrigation entitlements held in the region as a result of the Murray Darling Basin Plan.

This report, commissioned by Namoi Councils, presents the results of Deloitte Access Economics’ modelling of the economic impacts of a drier future on the Namoi economy. The impacts of a drier future have been modelled using three integrated models:

  1. A water and landuse model of the Namoi Catchment
  2. A Computable General Equilibrium (CGE) model with the Namoi Catchment as a discrete region in the global economy
  3. A community level disaggregation resilience model.

The value of water assessment reflects the combined outputs of the three models, when used to model the effects of declining water availability in the Namoi Catchment.
