Hearing the call: How Timor-Leste is reaching the "last mile" with Early Warnings

Timor-Leste is a nation of striking landscapes, but its geography also places it on the frontline of climate extremes. From sudden flash floods and devastating landslides to prolonged droughts and cyclones, communities face a growing array of natural hazards.

But when a storm is brewing, how does a remote mountain village know it's time to seek safer ground?

To answer this, an important study supported by the Climate Risk and Early Warning Systems (CREWS) initiative, coordinated by the United Nations Office for Disaster Risk Reduction (UNDRR) and conducted by the Red Cross Red Crescent Climate Center, set out to understand the real-world reach of Timor-Leste's early warning systems (EWS). By surveying 909 households and conducting 27 focus group discussions across eight municipalities, researchers went straight to the source - the communities themselves - to uncover what is working, what isn't, and who is being left behind.

Here is what the data revealed about the realities of surviving a disaster in Timor-Leste. 

The "digital divide" reality check

It’s easy to assume that a mobile app or an SMS blast is the ultimate solution to reaching people with early warnings. However, the study uncovered a stark digital divide. While a highly respectable 84% of households own a mobile phone, 56% of rural households face weak coverage - or have no network at all, most of the time.

For more than half the population, a high-tech digital warning system would be effectively silent. The study sends a clear message: to truly reach the "last mile," the country must combine digital innovations with reliable low-tech solutions. Sirens, radio broadcasts, and megaphones remain critical for rural communities. 

Trust is local

Who do you trust when your life is on the line? In Timor-Leste, the answer is overwhelmingly local.

The study found a remarkably high level of trust in early warning messages (nearly 90%), but this trust is anchored in the people delivering them. In areas without internet, communities rely heavily on announcements from local authorities (village and hamlet chiefs). Communities trust leaders who speak their local dialect and understand their context. Moving forward, empowering these local leaders to act as the primary nodes for disaster communication will be far more effective than relying solely on distant, national-level broadcasts. 

Lost in translation: when jargon kills action

Receiving a warning is only half the battle; understanding it is the other. While most people surveyed found previous warnings understandable, nearly one in four households struggled.

The primary culprits? Language and technical jargon. Nearly half of those who didn't understand the warnings said the messages were "too technical" (48%), and a quarter noted they were not in their local language. In a country rich with linguistic diversity, a one-size-fits-all message in official Tetum often falls short. Translating warnings into local dialects (like Mambae, Kemak, and Makasae) and swapping scientific jargon for clear, actionable instructions is a vital next step. 

The inclusion gap: who gets left behind?

A recurring theme in the focus groups was that disasters do not impact everyone equally. In 21 out of 24 villages surveyed, communities stated that the current EWS requires significant enhancement to reach those who are at increased risk of disasters.

Youth, with their smartphones and social media, often receive warnings first. Meanwhile, older adults, women, and persons with disabilities are often forced to rely on slower, word-of-mouth chains. To bridge this gap, the study recommends targeted, inclusive strategies: using visual aids, sign language, and tactile communication for persons with disabilities, and ensuring that evacuation protocols consider those with mobility challenges.

From warning to action

Ultimately, an early warning is only successful if it triggers prompt action. Encouragingly, 79% of households took action upon receiving a warning — evacuating, securing their homes, or helping neighbors.

But what about the 21% who didn't? They cited barriers such as a lack of safe shelters, a lack of transport, or simply receiving the warning too late (18% of respondents received less than 6 hours' notice). To fix this, Timor-Leste is shifting toward "Impact-Based Forecasting" — telling people not just what the weather will be, but what it will do, coupled with community drills and safe evacuation routes.

A resilient future

Timor-Leste's communities already possess strong social bonds and deep traditional knowledge regarding the environment. By leveraging the support of CREWS, the government and its partners now have the hard evidence needed to build an early warning ecosystem that honors local trust, bridges the digital divide, and ensures that when the next storm comes, absolutely no one is left in the dark. The study's findings set a baseline for monitoring Timor-Leste's progress on early warning systems under the Sendai Framework (Target G). Moving forward, this evidence will directly aid the Government in improving EWS coverage and service delivery. Additionally, the data provides practical guidance for the Timor-Leste Red Cross, UN agencies, and other development partners to strengthen their community preparedness initiatives and last-mile reach of early warning.
