Abstract

[Extract] It has long been perceived that the ecosystems of the Great Barrier Reef (GBR) are threatened by increased loads of suspended sediment, nutrients and pesticides due to land-use changes following the arrival of Europeans. Hence it is critical to synthesise the available evidence that documents the key land-use changes that have likely produced changes in riverine exports as well as the proxy-based evidence (i.e., environmental indicators that have the ability to quantify changes in terrestrial runoff) and modelling that quantifies the changes in river discharge and associated loads over this period. The catchment and marine proxy records also provide insights on the detection footprint that changes in loads have had at both spatial and temporal scales and serve as key background for several questions in the 2022 Scientific Consensus Statement (SCS).
