The science behind ecoMarkets
A large part of the science driving ecoMarkets is based on mapping Victoria into 20-metre grids. This level of landscape detail is a first for Victoria and possibly the world. The new landscape modelling techniques make it possible to identify the contribution that each 20-metre grid can make to improving environmental outcomes.
At its most basic level, this grid system characterises how each 20-metre area fits into the overall ecosystem. This detailed knowledge of the unique aspects of any particular location in the landscape allows prediction of the catchment scale impacts of any land management action or group of actions. For example, revegetating along a stream with indigenous plants creates improved habitat for native flora and fauna, filters runoff water that reduces sedimentation and harmful nutrients from entering the stream and finally captures carbon. However, this revegetation will also use water that will not be available for aquatic flora and fauna or consumptive purposes downstream. Developing the science to understand these interactions is critical if we are to make real improvements to the environment and avoid potentially unwanted outcomes.
So for the first time we can accurately identify and assess environmental ‘quality’ and judge the relative dollar value of potential improvements to the land. This means we can more easily report on the condition of our ecosystems and quantify in dollar terms the contribution the environment makes to the Victorian economy.
Critically, this science will be delivered in a form easily understood by land managers and decision-makers, known as EnSym - Environmental Systems Modelling Platform (formerly known as the Catchment Management Framework or CMF).
EnSym - Environmental Systems Modelling Framework
EnSym is a computer program designed by the Victorian Government to model the impact on the environment derived from actions in the landscape. By understanding this impact, we can make more informed decisions about how to spend Natural Resource Management funds for maximum environmental value.
EnSym uses spatial information such as climate data, elevation, vegetation type, soil type and land use to model outputs such as surface water and ground water dynamics and native habitat changes. Models are widely sourced from leading credited scientists in their field.
