Software and models

Wageningen Environmental Research (Alterra) develops a variety of models, for example, to test the suitability of a habitat for flora or fauna or with which to make harvest forecasts on the basis of metrological and climate data.

The quality of the models is ensured through a process of continuous improvements and a demonstrable product quality. For product quality, objective and verifiable criteria are developed.

This modelling software can be used in all projects and assignments. Its quality is safeguarded by a proces of continuous improvement and by product certification.


So far, this modelling software has only been used in the projects for which it was developed. Its quality cannot yet be safeguarded and its applicability in a different context has to be reviewed on a case-by-case basis.
