Question 11.   Explain the issues with using targets in environmental decisions.

Include examples to illustrate your point. (10 marks)

Question 12.   Explain the differences between cost-benefit analysis and cost-effectiveness

analysis. Provide an example of each approach. (8 marks)

Question 13.   Describe the concepts of a dominated alternative and an efficiency frontier. Use a figure showing cost versus environmental impact to illustrate your answer. (12 marks)

Question 14.   Uncertainty is an important component of environmental problems. One way to articulate uncertainty is as hypotheses.

Question 15.   Below is a consequence table for an environmental problem. A coastal

community has been approached by three different industries (Tourism, Aquaculture, and Oil), hoping to develop the water just offshore. The community would like to maximise the benefit they receive through providing revenue and jobs to the local economy, while minimising the impacts on aesthetics, public health from water quality, and biodiversity of the area.

Simplify the consequence table, then using the swing weighting results provided and the simplified consequence table, calculate the expected utility of each alternative (show your working).

Note that cleaning up pollutants from each industry costs $1 million for each part per tonne (ppt) of pollutants, which would come out of the projected profit.

Based on your calculations, which alternative would you recommend to the community and why? (30 marks)
