WISE model update to version 1.6, reference scenario and Waikato land use projections (TA and SA2 level) 2018 to 2068

Report: TR 2021/31

This report summarises several workstreams that were undertaken to update the WISE model and then develop the land use projections as part of the 2018 Waikato Projections.

The methodology and results for the economic (value add, employment) and social (population, households, labour force) data of the Waikato projections are presented in separate reports (Cheon and McDonald, 2021; Cameron and Cochrane 2021a, b).

The workstreams covered in this report are presented in four parts:

Part 1 of this report outline the process and changes made to update the WISE model to version 1.6.

Part 2 outlines the Reference Scenario in the new version 1.6 of WISE. 

Part 3  outlines the links between the various modelling processes undertaken to create projection data at the Statistical Area 2 (SA2) level for the Waikato region, from a baseline in 2018 to 2068 (50 years time horizon). 

Part 4 describes how future land use projections for the Waikato were generated from the updated WISE model (Waikato Regional Council, 2021) and how these were then processed to provide a set of land use projections at the Statistical Area 2 (SA2) level for the Waikato region.
