Impacts Water

The majority of Fiji’s population (around 70%) and industry depend on surface water resources. Rainwater harvesting systems are also common. As identified in Fiji’s Second National Communication (2014), these resources are highly vulnerable to climate variability, particularly changes in the frequency and intensity of extreme events. For this reason the uncertainty in climate projections represents a challenge for planning and management. A need has been identified for greater storage capacities for periods of water scarcity, improved robustness to storm damage and extreme rainfall events, and stronger systems for dealing with pollution and water quality issues. Key areas of focus will include the management and upgrade of storm water drainage systems. The Government of Fiji identifies soil erosion and landslides during extreme climate-events as a particular risk to key water infrastructure. Flooding is also a key issue, with more than 20% of water resource assets (intake stations, boreholes, pumping stations, and water treatment plants) lacking any waterproofing.

This section provides insights into projected climate change impacts on various hydrological indicators.


Data presented under Historical Climate Conditions are reanalysis products derived from ERA5-Land data. ERA5-Land is a global land-surface dataset at 9 km resolution, consistent with atmospheric data from the ERA5 reanalysis from 1950 onward. Climate reanalyses combine past observations with models to generate consistent time series of multiple climate variables. They provide a comprehensive description of the observed climate as it has evolved during recent decades, on 3D grids at sub-daily intervals. 

This data has been collected, aggregated and processed by the Climate Resilience Cluster of the European Space Agency’s (ESA) Earth Observation for Sustainable Development (EO4SD) initiative.
