Scaling Up the Soasoa Drainage System, Fiji

The ‘Scaling up the Soasoa drainage system, Fiji’ project will enhance the efforts of previous projects to protect vulnerable coastal communities in the Macuata Province, especially the Soasoa community in Labasa, from coastal flooding and inundation through implementation of prioritized flood control measures in the Soasoa watershed area.

Project Focus: Coastal Protection

Direct benefit: 4,140 persons
Indirect benefit: 35,947 persons

  • Geographic coordinates: Lat. 18°10’S, Long. 178°27’E
  • Total land area 18,272 km²
  • Exclusive economic zone (EEZ) 1,282,980 km²
  • Population (2017 census) 884,887
    • Temperatures have warmed and will continue to warm with more very hot days in the future.
    • Annual rainfall in Fiji is not projected to change significantly but rainfall may increase in the November–April season with more extreme rain events.
    • Sea level will continue to rise throughout this century.
    • Ocean acidification will continue to increase in Fiji. It will continue to increase and threaten coral reef ecosystems.

How does this project address climate change adaptation in Fiji?

In the Soasoa drainage area levees protect the reclaimed area and a series of floodgates discharge water during low tide. The infrastructure was designed in the 1970s and there is now a need to strengthen this infrastructure to address changes in the climate such as rising sea levels, changing rainfall patterns and extreme rainfall events and associated runoff. This adaptation measure supports the Fijian Government’s efforts to enhance the resilience of vulnerable coastal communities to climate change, articulated in the 5 and 20-Year National Development Plan, the National Climate Change Policy and the National Adaptation Plan.

Focusing on the people and communities living in the Soasoa watershed area, the project will adopt a participatory and inclusive approach that addresses the vulnerabilities and the rights of all residents. Skills in climate resilience will be enhanced, particularly for provincial and district government officers and community leaders. The project will focus on constructing prioritized flood control measures such as flood gates and raising the levees, upgrading of existing spillways and widening of channels along the Soasoa drainage area. Management of the Soasoa watershed to complement hard flood control infrastructure will be a key component of the project. A 30-year (2020 – 2050) watershed management plan for the Soasoa watershed will be developed, in consultation with communities and stakeholders, and will be supported by an action plan.
