Query: Predicting Drought and Subsidence Risks in France   The economic consequences of drought episodes are increasingly important,
although they are often difficult to apprehend in part because of the
complexity of the underlying mechanisms. In this article, we will study one of
the consequences of drought, namely the risk of subsidence (or more
specifically clay shrinkage induced subsidence), for which insurance has been
mandatory in France for several decades. Using data obtained from several
insurers, representing about a quarter of the household insurance market, over
the past twenty years, we propose some statistical models to predict the
frequency but also the intensity of these droughts, for insurers, showing that
climate change will have probably major economic consequences on this risk. But
even if we use more advanced models than standard regression-type models (here
random forests to capture non linearity and cross effects), it is still
difficult to predict the economic cost of subsidence claims, even if all
geophysical and climatic information is available.
