Why an integrated system of models?
Whereas climate change is a growing concern for decision-makers, information on the impacts of climate change is often lacking or incomplete. In agriculture in particular, crop production will be affected by a combination of factors (effects of changes in temperature and precipitation regime on plant physiology, changes on growing season onset and length, CO2 fertilization effect, technological improvements, water availability for irrigation etc.) of which interactions are rather complicated. In this context, combining different models in a single modelling system offer a large number of advantages:
- Data: data transfer is made easy, efficient and transparent. No data formatting, all the data used and produced can be consulted in the database and retrieved for other applications. Information on the production processes used to obtained them is also available. Data can be also shared with external users.
- Time consumption: thanks to the data transfer efficiency and the installation of the models on a powerful server, the time necessary to make simulations is reduced
- Study design: the centralization of the tools and the data gives a better control over the processes and the data flow and facilitates the design of multi-disciplinary projects involving a wide range of experts with different background (agrometeorologists, hydrologists, economists etc.)
- Inter-comparison: the standardization of robust methods and tools allows users to carry out impact studies in different areas and to obtain results that can be compared.
Further information on the system and the models is available in the "Models" and "Software Architecture" sections of the website.
