Short Summary

This study evaluates the effectiveness of satellite-derived precipitation and vegetation health products in monitoring agricultural drought conditions in Timor-Leste, demonstrating their potential as valuable tools for proactive drought management.

Objective

• Investigate the feasibility of using satellite-based indices to monitor drought conditions in Timor-Leste

Study Configuration

• Spatial Scale: National scale (Timor-Leste)
• Temporal Scale: Near real-time monitoring with a focus on the 2015/16 El Niño-induced drought event

Methodology and Data

• Models used: Standardised Precipitation Evapotranspiration Index (SPEI) and Vegetation Health Index (VHI)
• Data sources: Satellite-derived precipitation data, vegetation health products from NASA's MODIS instrument

Main Results

• Both SPEI and VHI successfully represented the onset, peak, end, and severity of the 2015/16 drought conditions in near real-time.
• Correlation analysis showed strong agreement between satellite-based indices and surface-based precipitation observations (r = 0.74 for SPEI and r = 0.79 for VHI).

Contributions

This study provides original insights into the application of satellite-based drought monitoring in Timor-Leste, highlighting the potential benefits of proactive drought management strategies.

Funding

• This research was supported by the Australian Government's Department of Foreign Affairs and Trade (DFAT) through the Australian Aid program.
