I’m going to make a couple of comments on the recent report. I’m writing this as I generally find this an area that is poorly understood. I used to work for the CRC for Tropical Pest Management (1994-99), and this is an area where the economics could be improved. However, notable economic contributions to this area have been made by Clem Tisdell and David Pannell.
Before we get started, some terminology:
Hopefully this terminology clarifies some of the language and illustrates how changing density within a pest-load alters costs, and/or entrance of a new pest doesn’t necessarily mean that more costs are required as existing strategies could deal with the entrance of a new species.
The cost associated to a species is a combination of their density (impacts on management type and associated costs) and the distribution (the area they cover). Decision makers generally manage a pest-load on the area they are responsible for, as there is just never one pest, and (for this story) management solutions target multiple species.
For economics, the difference between pest management and bio-security is important as:
A bio-security incident can be caused by:
Understanding pest management expenditure
So a couple of things from that newspaper article:
As Australian exporters have to pay costs to meet market standards, it seems one sided:
Post-DECRA I’ll be doing some work again in this area but with a focus on one-health, animal diseases and international trade.
