Title 

An economic comparison of risk handling measures against Hylobius abietis and Heterobasidion annosum in the Landes de Gascogne Forest

Abstract

• Key message

Phytosanitary risks are an increasing threat for forest, particularly due to climate change. Risk handling measures are effective economic strategies to manage such risks, so that Economics may provide relevant methodology to address this new challenge.

• Context

Hylobius abietis and Heterobasidion annosum are two phytosanitary risks generating increasing damage in the Landes de Gascogne Forest.

• Aims

We provide an economic comparison of different existing risk handling measures against Hylobius abietis and Heterobasidion annosum.

• Methods

We use the Land Expectation Value, i.e., Faustmann criteria, to compare the different scenarios

• Results

We find that for Hylobius abietis, chemical treatment and fallow seem to be economically preferable to the absence of risk handling measure. For Heterobasidion annosum, we show that local stump removal is always preferable to total stump removal and chemical treatment. Local stump removal should be preferred to fallow when contamination occurs during the second thinning. Finally, our results indicate that fallow is always preferable to chemical treatment.

• Conclusion

Beyond the specificities of the case study, the paper proposes amethodology to analyze such a problematic.
