Securing Groundwater in Timor Leste

With Timor-Leste’s groundwater supplies projected to become increasingly vulnerable to shortages and sea water intrusion with climate change, it is critical that safe and reliable water is maintained for communities.

The people of Timor-Leste, like many island countries, depend heavily on groundwater supplies for cleaning, cooking and growing their crops. The nation’s 1.1 million population is set to triple by 2050.

Timor-Leste worked with the Australian Government’s Pacific Adaptation Strategy Assistance Program (PASAP) to:

• Assess the vulnerability of groundwater supplies to climate change impacts
• Produce a national plan outlining how to collect, categorise, map and monitor groundwater
• Map aquifers and help improve development planning
• Implement training programs for monitoring and analysing groundwater data and maps

“We trained Timor-Leste government staff on reproducing our hydrogeological monitoring, mapping and analysis and developed a national hydrogeology map for Timor-Leste which was the first of its kind for the country.” – Luke Wallace, Geoscience Australia
