Targeting conservation payments to achieve multiple outcomes
This paper describes an environmental conservation planning model used in Queensland, Australia to purchase agreements on 66 sites covering 81,046ha at a cost of A$1.9 million. The model was used as part of a competitive tendering program called “NatureAssist”. The model maximises conservation benefit subject to a cost constraint using binary combinatorial optimisation. Multiple criteria analysis (MCA) is used to capture investor preferences and measure benefit over multiple outcomes. Conservation costs are drawn from real market data; i.e.
