Introduction: The Céréopa, who are we?

The PerfAgro® approach

Case study: The experimental farm of Grignon

Conclusion

Created in 1969 at the INA P-G (Paris-Grignon National Institute of Agronomy), France’s leading School in the fields of Agronomy and Life Sciences

Our fields of Competences:

• Integrated modeling of production systems• Competitivity and sustainable performance of agro-activities• Foresight, innovation and strategic decision making

Our activities:

• Education• Consulting• Research

A team of four Engineers (MSc. and PhD.) and a Professor of the INA P-G

Center for Studies and Research on Economics and Organisation of Animal Productions

GLOBAL PERFORMANCEof the system described into details

LIVESTOCKCROPS

PerfAgro ®: A global approach which gives diverse and precise indicators of sustainable performance

Economicmargin(€/year)

Diets of dairy cows atdifferent stages of

lactation duringthe winter

Quantity of work(hours/year)

Fossile energyuse on the farm

(MJ/year)

Constraints costs(milk quota

farm area, etc.)

Examples of output indicators:

Etc.

PerfAgro ®: A new approach of questions which widens the response spectrum

PROTEIN AUTONOMY

CLASSICAL APPROACHES

Ration calculations to replace soya by rapeseed

With PerfAgro, many new opportunities appear:

> Choice of crop rotation> Rapeseed crushing > Level of intensification> Etc.

Example : the issue of protein autonomy on a farm

PerfAgro ®: A tool in development

Limited for the while to

Other productions:

Being developed: risks management, global energy use on the farm minimization, bursts of work, environmental indicators.

Necessity of a global approach

Where are the levers of sustainable performance of dairy production systems ?

Conclusion

PerfAgro: Beyond decision making…

An approach of the complexity of agricultural systems which gives the possibility to benchmark varied breeding systems in different situations

Sustainable agriculture: a complex issue> Simplification is not always the best

> Why not trying to get opportunities from it ?

In France… …and abroad…
