We are happy to announce the publication of a paper relevant to Coral_List
readers in *Nature Communications* this week by a coalition of ecologists,
geographers, and oceanographers from academia, government, and an
international conservation organization. This research demonstrates how
maintaining or restoring coral reefs ecosystems can not only reduce coastal
hazards, but how such efforts are more cost-effective than hard
anthropogenic engineering structures. This research links coastal hazards
and ecosystem health while providing insight into the cost-benefit analyses
that often drive many management decisions.

Title:
The effectiveness of coral reefs for coastal hazard risk reduction and
adaptation

Abstract:
The world’s coastal zones are experiencing rapid development and an
increase in storms and flooding. These hazards put coastal communities at
heightened risk, which may increase with habitat loss. Here we analyse
globally the role and cost effectiveness of coral reefs in risk reduction.
Meta-analyses reveal that coral reefs provide substantial protection
against natural hazards by reducing wave energy by an average of 97%. Reef
crests alone dissipate most of this energy (86%). There are 100 million or
more people who may receive risk reduction benefits from reefs or bear
hazard mitigation and adaptation costs if reefs are degraded. We show that
coral reefs can provide comparable wave attenuation benefits to artificial
defenses such as breakwaters, and reef defences can be enhanced cost
effectively. Reefs face growing threats yet there is opportunity to guide
adaptation and hazard mitigation investments towards reef restoration to
strengthen this first line of coastal defense.
