DO FLOODS OR DROUGHTS CAUSE MOST CROP DAMAGE IN CANADA?
A recent news article piqued my interest as it suggests that in recent years floods have been the major driver of crop damage in the important agricultural states of Saskatchewan and Manitoba in Canada.
If crop insurance data is an indicator, flooding may now be the most common plague in Saskatchewan. Statistics from the Saskatchewan Crop Insurance Corp. show […]

Similarly to the interviewee in the article, I was under the assumption that droughts would be most damaging given their larger spatial extent. So what is going on? Perhaps the intensification of the hydrological cycle, as expected under anthropogenic climate change, is having a notable impact in Canada by increasing the intensity of rainfall events.
The article goes on to say that:
drought still presents the largest financial risk for the insurer …[because] … losses from a wet year are usually lower because the entire province is rarely inundated with water. Typically, if part of Saskatchewan gets too much rain, the other regions have a sufficient amount of precipitation.
Which seems to back up my initial assumption. So what seems to be happening is an increase in frequency of flooding events and/or a relative decrease in frequency of major drought events in the recent past. Which serves as a reminder of the difficulties in understanding and pricing risk in this era of a changing climate.
