What are we doing?E aha ana mātou?

Transitioning New Zealand’s agricultural landscape to a more diverse and resilient mosaic of land uses requires understanding how land management and water quality interact, and how targeted management can achieve our shared values. This requires our ability to model these interactions using open-source interoperable models feeding off low- or no-cost, readily available and high-quality data.

Interoperable Modelling research is developing a national modelling system that assesses the environmental, production and economic implications of land use and land use change, at farm and catchment scales. The goal is to create a trusted tool that helps individuals and communities achieve agreed land and water quality outcomes.

Researchers have identified an agreed initial set of models, data sources, and visualisation components, and are working with a software platform for integrating and accessing the components. Our programme is co-funded by stakeholders to provide a platform where the best models can ‘talk’ to each another.

How can the research be used? Ka pēhea e whai take ai te rangahau?

  • The Interoperable Modelling science team is working to implement a functioning and interoperable set of models. The platform is being built on the best available data to provide much faster, cheaper analyses and visualisation experiences. Outputs will enable the measurement of national scale change (eg land use) and regulatory limits.
  • There are 10 parties actively involved with the development of the platform through contributing data, sharing code, creating solutions and co-funding. A comprehensive report on interoperable modelling was prepared collaboratively with input from technical experts from 14 organisations.
  • An initial set of models was implemented in the open-source DeltaShell framework and trialled in Aparima catchment in Southland.
  • The initial set of models will focus on contaminant generation and transport, water resources and optimisation, in static and dynamic catchment models.

The Duke of Edinburgh (third from left) observes border dyke irrigation at the Winchmore Research Station Irrigation Scheme. In a border dyke irrigation system, when water is diverted from the main water races into smaller ones, a temporary dam must be created at the outlet to each border, so the water spills through onto pasture. In this image the outlet behind the worker in the water has been closed with a board, the pasture on the right of it has been flattened by the previous flow of water. The worker is lifting a corner of the canvas dam to allow water to flow down to the next temporary dam.
