Chapter 9 Insurance
This chapter describes the many ways in which natural systems protect people from extreme events.
Pages 221-224. At the start of this chapter I write about the relative damage caused by Hurricane’s Katrina and Rita. This part of my book was informed by Mashriqui, H. S. et al. (2007). Coastal wetlands reduced storm surge from hurricanes. Unpublished. I was passed this paper by one of Hassan Mashriqui’s co-authors and although it was unpublished I judged that the material contained within it was rigorously presented and analysed, and so decided to include some of its findings in this chapter.
Pages 225-226. I mention several pieces of research describing how areas with intact coastal mangroves and/or coral were more protected from the impacts of the 2004 Indian Ocean tsunami that those areas without. In relation to the impacts on the coast of South-east India I drew on work from Finn, D. et al. (2005). The Asian Tsunami: a protective role for coastal vegetation. Science, Vol. 310. 643.

Pages 225-228. For readers wishing to delve deeper into the literature on the extent to which trees can mitigate the impact of tsunamis, FAO has produced a very helpful bibliography. It can be seen at: http://www.fao.org/forestry/13416-0dfb9153906beba03a60a348bd8dd943d.pdf
Page 227. I mention a figure sourced from a UNEP report estimating how healthy coastal ecosystems can take between 70 to 90 per cent of the energy out of a wind generated wave. UNEP-WCMC (2006) In the front line: shoreline protection and other ecosystem services from mangroves and coral reefs. UNEP-WCMC, Cambridge, UK.

Page 230. I mention how speculation emerged following the passage of Hurricane Sandy over New York in late 2012 as to the possible role that could have been played by oyster beds in mitigating the impact of the storm. This piece for example appeared in the New York Times: http://www.nytimes.com/2012/10/30/opinion/an-oyster-in-the-storm.html?adxnnl=1&adxnnlx=1351609339-DPYEWDuXIhwxL2omszU2hQ&_r=0
Pages 230-231. Belize’s coral and mangrove systems have a huge economic value for the country. The figures I cite on this subject come from a WRI/WWF report. Cooper, E. et al. (2009).
