Short summary

Beach erosion is one of the leading problems that coastal regions face worldwide, and coastline evolution studies show how much it affects the coastal system. Usually these studies are site-specific and lack an integrated approach to either a large spatial domain or quantification using a single measurement. The first global Portuguese study on the subject is presented using an integrated approach. Results show erosion as dominant trend (−0.24 m year⁻¹), but it is highly variable in space.
