Traditional mapping and scientific communication methods are recognised as falling short of expectations about the way they influence change in environmental management funding decisions. These techniques have remained largely untouched for the past 40 years, revealing a need to better communicate and visualise the relationships between natural systems, people, economics, and management actions using modern digital tools. In a world first, key solutions from the innovative spatial modelling tools developed by the Building Catchment Resilience (BCR) Project (https://www.catchmentresilience.org/) can be used to identify potential solutions for optimal on-ground investment that reduce catchment erosion and associated pollutants, minimize flood risk and quantify other co-benefits (e.g. carbon sequestration). Effective engagement with stakeholders to explore the range of management outcomes and scenarios for investment must build confidence, not only among investors wishing to fund major restoration projects (e.g. to offset the cost of wastewater or drinking water treatment), but also with local landowners, who may want to host and manage on-ground projects and would like to understand the full costs and benefits. Key solutions from the BCR modelling tools can be selected by stakeholders and explored in a virtual reality (VR) environment.  The VR application incorporates a Digital Elevation Model, satellite imagery, spatial layers used in the modelling process, generative atmospheric effects and cinematic techniques to visualise a high-level view of the catchment. Other catchment-scale benefits, including flood-risk reduction can also be explored and visualized.
