Cost-Benefit Analysis: Water Project
What next?
• Consult with climate scientists
– Identify most likely climate scenario in the next 30 – 60 yrs
at the project sites
• Consult with water resource engineers
– Identify proper alternatives for CC adaptation
– Get estimates of the costs of those alternatives
