75% of the World’s sandy beaches are stable or growing

Analysis of satellite derived shoreline data indicates that 24% of the world’s sandy beaches are eroding at rates exceeding 0.5 m/yr, while 28% are accreting and 48% are stable. Coastal zones constitute one of the most heavily populated and developed land zones in the world. Despite the utility and economic benefits that coasts provide, there is no reliable global-scale assessment of
historical shoreline change trends.

By using freely available optical satellite images captured since 1984, in conjunction with sophisticated image interrogation and analysis methods, a global-scale assessment of the occurrence of sandy beaches and rates of shoreline change was undertaken. This found that 31% of the world’s ice-free shoreline beaches are sandy. Analysis of satellite derived shoreline data for the 33-year period 1984–2016 indicated that 24% of the world’s sandy beaches are eroding at rates exceeding 0.5 m/yr, while 28% are accreting and 48% are stable. The majority of the sandy shorelines in marine protected areas are eroding, raising cause for serious concern.
