Last week I sent a fairly random Tweet about deforestation in south-eastern Queensland being partially responsible for the record floods there. It went more or less unnoticed, but I thought the comment deserved a proper explanation.
As many of you might know, my colleagues and I wrote an article a few years ago about the global-scale evidence for deforestation leading to a higher incidence and severity of floods in the developing world. This was fairly controversial, but it was nonetheless the first broad-scale evidence for the fabled deforestation-flood link yet published (in my not-so-humble opinion). Subsequent comment reiterated the point with new data.
Now, I will begin by saying I have no data yet to back up my Queensland-specific hypothesis, but I am contemplating a time-series paper on floods in Australia, especially after the events of the last month. This post is therefore merely a reasoned hypothesis.
The hypothesis itself is rather simple. Testing is not. I submit that the recent flooding in Australia has been exacerbated (not caused) by the rapid loss of forest cover over the last 40 years. We know that this is a particularly intense La Niña in Australia and our unusually high rainfall arises from this meteorological phenomenon, but I hypothesise that it wouldn’t have been as bad if this part of Australia hadn’t been so careless with its forest cover since the 1970s.
