Modelled Total Visitation Value of Coral Reefs (per km2)

The layer comprises mapped estimates of annual visitation to coral reefs. These values are taken from the combined value of on reef values and reef adjacent values, the former including recreational diving and snorkelling and the latter including the provision of calm waters, coral, sand beaches, views, and seafood.

Lineage	Global data from multiple sources, including social media and crowd-sourced datasets, were used to estimate and map two distinct components of reef value. The first component is local “reef-adjacent” value, an overarching term used to capture a range of indirect benefits from coral reefs, including provision of sandy beaches, sheltered water, food, and attractive views. The second component is “on-reef” value, directly associated with in-water activities such diving and snorkelling. Tourism values were estimated as a proportion of the total visits and spending by coastal tourists within 30 km of reefs (excluding urban areas). Reef-adjacent values were set as a fixed proportion of 10% of this expenditure. On-reef values were based on the relative abundance of dive-shops and underwater photos in different countries and territories.
