Examining the existing methodologies reveals a number of important points from the perspective of farmers and landowners:
-
The methodologies will require a level of data collection and monitoring that is beyond normal practice for the farming enterprise.
-
Some methodologies may require the use of specific modelling tools. This also suggests some form of specialist involvement in the ERF project.
-
They may require sampling, measurement and statistical techniques that are very specialised. This implies that the farm enterprise will probably have to contract at least some of those services.
