Hypothesis
How much will it cost to expand the protected area system in Queensland while accounting for uncertainties?
Conclusion
The estimated costs for expanding protected areas in Queensland range from $214 million to $2.9 billion, depending on various assumptions.
Supporting Evidence
- The Queensland government committed to adding approximately 12 million hectares to the reserve system by 2020.
- Cost estimates varied significantly based on assumptions about land acquisition routes and biodiversity objectives.
- Unexpected costs were found to be non-linear and sensitive to the ability to subdivide properties.
Takeaway
This study looks at how much money it will take to make more nature parks in Queensland, and it shows that the costs can be very different based on what you assume.
Methodology
The study used sensitivity analysis and the Marxan tool to estimate costs based on different scenarios of biodiversity objectives and land acquisition.
Potential Biases
There is a risk of underestimating costs due to optimistic assumptions about landholder willingness to sell or subdivide properties.
Limitations
The study's estimates are based on assumptions that may not hold true in real-world scenarios, leading to potential inaccuracies.
Participant Demographics
The study focuses on landholders in Queensland, Australia, but does not provide specific demographic details.
