Robert J. Johnston presented on ‘Quantifying the Non-Market Benefits of Coastal Adaptation and Natural Infrastructure: Implications for Benefit-Cost Analysis‘ on November 6th, 2019. The webinar focused on key trade-offs and economic values associated with different approaches to coastal adaptation, and what it means for adaptation that will be most beneficial to the public. Dr. Johnston talked about trade-offs between green and grey infrastructure for coastal adaptation and the benefits and costs that can result. The focus of the webinar was how economists conceptualize and measure the benefits and costs of coastal adaptation, with particular emphasis on more difficult-to-quantify non-market benefits. It covered the difference between financial (or accounting) benefits and costs and economic benefits.
