Integrated Impact Assessment Framework (updated March 2024)

The purpose of this integrated impact assessment (IIA) framework is to allow exploration of scenarios where land use is changing for a specified region of New Zealand. The framework shows the impact of land use changes on economic, social, cultural and environmental indicators.

The tool has been designed to be used by councils however the layperson should also be able to use it to make broad assessments and understand the complex nature of the impacts of land use change.

There are three ways for specifying scenarios, a form for applying region-specific data, and two dashboards providing overviews and detail signalling likely impacts.

The framework has been developed for two case study regions, the Ashburton district and Mosgiel. The land uses and indicators in the framework were chosen by stakeholders. The particular issues examined to aid the development of the framework were the impact of land use changes associated with nitrate leaching and peri-urban development.

March 2024 update: The .zip file below contains a main Excel file and a secondary ‘helper’ Excel file that allows the main model to bring in the right economic data, plus a guide to operating the framework.
