Have you ever been in a position where you had to make a decision but you were torn by conflicting objectives? Well, that is a very common issue when managing an invasive species that is also valuable for society. Unfortunately such a situation often paralyze the decision making process. In a recent paper to appear in Agricultural Systems led by Isabelle Grechi, we looked at how we could model such decision problem and propose valid solutions based on our so-called conflicting objectives. We introduce happyness curve to do so! We applied our decision framework to buffel grass (it doesn’t get more controversial than this plant in Australia!).
Have a look at the paper:
Grechi, I., I. Chades, Y. Buckley, M. Friedel, A. C. Grice, H. P. Possingham, R. D. van Klinken, and T. G. Martin. 2014. A decision framework for management of conflicting production and biodiversity goals for a commercially valuable invasive species. Agricultural Systems 125:1-11.
- • Commercially valuable invasive species present a conflict for management.
- • We model buffel grass dynamics with production and biodiversity benefits and costs.
- • Management solutions are found that account for production-biodiversity trade-offs.
- • Solutions are sensitive to the shape of the buffel cover–biodiversity relationship.
- • Solutions are less sensitive to uncertainty about the management effectiveness.
