Scaling up water storage capacity in Nauru in response to climate change

The ‘Scaling up water storage capacity in Nauru in response to climate change’ project will provide water storage measures for desalinated water only. The project will focus on the most vulnerable households in different districts in Nauru.

Project Focus: Water Sector

Direct benefit: 500 persons
Indirect benefit: 9,584 persons

  • Geographic coordinates: Lat. 0.5°S and 167°E
  • Total land area 21 km²
  • Exclusive economic zone (EEZ) 320,000 km²
  • Population (2010 mid-year) 9,570
    • Temperatures have warmed and will continue to warm with more very hot days in the future.
    • Rainfall shows no clear trend since 1950. Rainfall is generally projected to increase over this century with more extreme rainfall days and less droughts.
    • Ocean acidification has been increasing in Nauru’s waters. It will continue to increase and threaten coral reef ecosystems.
    • Wave height and period are projected to decrease in December to March.
    • Sea level near Nauru has risen and will continue to rise throughout this century.

How does this project address climate change adaptation in Nauru?

The effects of climate change on temperatures, humidity, rainfall and weather extremes are affecting the quality and quantity of water resources available for residents in Nauru. In particular, drought and flooding events are major concerns.

With a small land area and very limited groundwater resources, access to potable water is a major concern. Presently Nauru does not have a reticulated water distribution system and relies on desalinated water, rainwater harvesting and groundwater – all of which require storage at the household level – to meet water needs. Presently, desalinated water accounts for 70-80% of water needs in Nauru.

Focusing on households with limited water storage, the project is adopting a participatory and inclusive approach that addresses the vulnerabilities and the rights of residents. Skills in climate resilience will be enhanced, particularly for district leaders and community representatives.

Recognising the need for increased water storage capacity at the household level, the project is building on water security efforts by the Government of the Republic of Nauru.

Using socio-economic indicators and an assessment of household water storage capacity, the GCCA+ SUPA project is providing increased storage for desalinated water for the most vulnerable households. Basic maintenance training and the provision of tools to recipient households will contribute to sustainability.

Key Highlights

  • Increasing water storage capacity
  • Building community resilience
  • Strategic planning
  • Developing and applying a methodology to identify the most vulnerable households for increased water storage capacity:
  • Assessing the impacts of previous water storage systems and applying the findings to the design of the increased water storage capacity.
  • Installing water storage measures for desalinated water only for the most vulnerable households in districts in Nauru.
  • Establishing agreements with each recipient household concerning installation, maintenance and monitoring of the water storage measures.
  • Delivering maintenance training and providing basic maintenance tools for recipient households.
  • Conducting a needs analysis and raising awareness about climate resilience for local area stakeholders.
  • Building the capacity of community leaders and district leaders in climate resilience through accredited training.
  • Integrating climate change and disaster risk into local area sustainable development plans.
  • Assessing the impacts of past climate change adaptation projects and applying the results to national strategic planning.
