Tracing the influence of land-use change on water quality and coral reefs using a Bayesian model

Abstract Coastal ecosystems can be degraded by poor water quality. Tracing the causes of poor water quality back to land-use change is necessary to target catchment management for coastal zone management. However, existing models for tracing the sources of pollution require extensive data-sets which...
