O. Deheuvels – Cirad - Cropping systems research unit
A tool for economical and technical modelling
and simulation of a farm or a group of farms
Olympe
Olympe and the farm system concept
Analysing the farm:
Livestock raising systems
Fallow lands and shifting systems
Tools and buildings
Total farm area.
Post harvesting systems
Cropping systems
Olympe to compare incomes and benefitsat the cropping system level
Simple and complex cropping system analysis :
Cultivated area for each crop
Varieties
Age of plantation
Density
Annual yield
Calendar of works realized in the plot
and their respective times and costs
Associated crops : varieties, yield...
Definitions of the items
Parameters definitions (Database)
The “arming system:
Livestock systems
Land reserves (Fallow lands, forests ...)
Tools, fixed assets and treasury
Labour force andworking calendar
Farm activities
Croping systems
The farm and the farming system
The production workshops
Cropping systems
annual crops, animals,tree crops or perennial
The farming system
Farming systems
The agricultural region

The regional approach: Sets of farmers
Regional analysis : groups of farms, typology
The uncontrolled external effects
Hazards on Prices and quantities variations
Customisation of outputs and results
Calculation options
Transfer to other software
