Blue Health Watch: Remote Sensing for Monitoring Water Quality and Climate-Sensitive Disease Risks

Abstract Climate change increasingly threatens water security and public health through degraded water quality and rising disease risks. This seminar explores how remote sensing technologies—such as Landsat, Sentinel-2, and MODIS—can monitor key water quality indicators including turbidity, chlorophyll-a, and surface temperature. By linking satellite data with health surveillance, the Blue Health Watch framework offers a low-cost, scalable approach for predicting outbreaks of waterborne and climate-sensitive diseases. The session highlights how integrating Earth observation, machine learning, and public health data can enhance early-warning systems and strengthen climate-resilient health strategies in Australia and the Indo-Pacific region.
