Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity at risk ranging from $2.4 billion to $3.1 billion in output. Increases in storm damage to capital stock range from $8.7 billion to as much as $133 billion with associated disruptions to economic activity ranging from an additional $1.9 billion to $23 billion in total lost output.

"Well-designed measures are essential for informing plans, decisions, assessments, and communications with key stakeholders. This toolkit provides a very brief overview of how to identify concepts that should be measured, how to evaluate measures, and how to identify new measures that can contribute to better-informed decisions, plans, and assessments. It is based on the content presented in a series of instructional, interactive workshops that RAND conducted for the Office of the Under Secretary of Defense for Policy in 2016 and 2017. This content was derived from a series of prior RAND reports, as discussed in the body of the document."--
