Baucau is one of the oldest and most historically significant municipalities in Timor-Leste. Once a key administrative and economic hub during Portuguese colonial rule, Baucau has long been regarded as a vital gateway to the eastern region. It is home to the country’s second-largest urban center and boasts a rich cultural heritage, fertile agricultural zones, and strategic coastal access.

Today, Baucau’s relevance remains clear. With a population of approximately 123,000 people (2022 Census) and a diverse geography ranging from lush highlands to rugged coastlines, the municipality plays a crucial role in Timor-Leste’s food production and regional connectivity. Agriculture is the backbone of the local economy, with thousands of households depending on rice, cassava, maize, and vegetable cultivation for both consumption and income.

Yet, despite its potential, Baucau faces serious development and climate-related challenges. Unpredictable rainfall, droughts, landslides, and the lack of resilient infrastructure have increased the vulnerability of communities. Roads are often impassable during rainy seasons, and water sources become unreliable during drought periods. These limitations directly affect education, healthcare, food systems, and livelihoods.

Recognizing the municipality’s significance and vulnerability, the United Nations Development Programme (UNDP), with funding from the Green Climate Fund (GCF), is implementing the project "Safeguarding Rural Communities and Their Physical Assets from Climate-Induced Disasters." In Baucau, this means addressing the dual priorities of strengthening infrastructure and restoring ecosystems to help communities build resilience and adapt to a changing climate.

Located on the eastern coast of Timor-Leste, Baucau Municipality is the second most populous region in the country, home to approximately 123,000 people according to the 2022 National Census. Encompassing an area of around 1,500 square kilometers, Baucau is a diverse and vibrant municipality consisting of six administrative posts: Baucau, Laga, Venilale, Vemasse, Quelicai, and Baguia. The region is known for its vast uplands, fertile valleys, and dynamic coastline that stretch from sea level to mountain ridgesgeography that offers opportunity and risk in equal measure.

Despite its agricultural potential, Baucau faces complex development challenges. Rural communities struggle with limited infrastructure, exposure to extreme weather events, and unreliable access to markets and services. Droughts, landslides, and water scarcity have increasingly disrupted food systems and transportation, undermining local livelihoods and public safety. For farmers, whose income depends on crops like rice, cassava, and maize, climate vulnerability is a daily threat.

Recognizing Baucau's strategic role in national development and its vulnerability to climate-induced disasters, the United Nations Development Programme (UNDP), with funding from the Green Climate Fund (GCF), is supporting a wide-ranging climate resilience program in the municipality. The project, "Safeguarding Rural Communities and Their Physical Assets from Climate-Induced Disasters," is delivering tailored infrastructure solutions while restoring ecosystems and empowering local communities.

Rural Roads as Lifelines: Connectivity for Development

Improving rural road networks is central to the GCF-supported interventions in Baucau. These roads are not just transportation corridorsthey are critical lifelines connecting communities to markets, schools, clinics, and administrative centers. The first road rehabilitation project under the GCF-funded initiative was completed in Suco Lavateri, Baguia Administrative Post, in early 2023. This 3.6-kilometer stretch from Lavateri to Onor Tibalari, benefiting over 1,780 people (including more than 840 women), was constructed by the local contractor Cuba Unipessoal Lda and officially handed over in March 2023.

Additional road works continued in 2023 and 2024 across key rural areas. The B-RR-03 (BaucauRoad Rehabilitation: AboLaisorulai de BaixoLelalai) scheme, rehabilitating roads from Suco Abo and Laisorulai de Baixo to Suco Lelalai, serves 785 residents. Two additional packages under B-RR-02 (Baucau Road Rehabilitation: BaguiaUatame and UailekileruBaguluru) are ongoing, targeting Suco Baguia to Uatame and Suco Guruca in area of Uailekileru to Baguluruhelping unlock access to highland communities previously cut off during rainy seasons. These investments directly improve mobility, enable market participation, and increase resilience during emergencies.

Water and Irrigation: Securing Livelihoods and Food Systems

Irrigation and water source protection are equally vital for Baucau’s rural economy. In 2023, UNDP-GCF delivered several irrigation schemes across Suco Fatulia, Soba, Bahamori, and Laisorulai de Cima, covering areas as large as 125 hectares and benefiting hundreds of farming households. These projects improve water availability for rice cultivation and other crops, while enhancing groundwater recharge and ecosystem services.

Under the scheme B-IS-07 (Baucau Irrigation: Bahadatu), a 450-meter irrigation channel was constructed to serve 33 farmers across 32.5 hectares. Under the scheme B-IS-04 (Baucau Irrigation: Bahamori), an 800-meter canal benefits 103 farmers and irrigates 125 hectares of farmland. Under the scheme B-IS-06 (Baucau Irrigation: Lugue, Butufalo Aldeia), the Lugue scheme now supports 33 farmers cultivating over 10 hectares. These systems directly support food security and community resilience, especially in areas prone to drought.

Looking ahead, multiple water supply projects are scheduled for 2025including B-WS-02 (Baucau Water Supply: Suco Badahoo and Uatuhaco) and B-WS-04 (Baucau Water Supply: Aldeia Ague and Loiborowai in Suco Seical). These projects will reduce reliance on seasonal sources and improve health outcomes for rural families.

Nature-Based Solutions: Reforesting for Resilience

Every infrastructure project is complemented by ecosystem-based adaptation strategies. Local NGO Raebia is implementing agroforestry and reforestation across vulnerable catchments, using tree planting and soil-bioengineering to stabilize land and protect infrastructure. In Bahamori alone, over 12,400 treesincluding fruit and non-fruit specieswere planted across 11.78 hectares. In other Sucos areas like Laisorulai de Cima, Lavateri,  Abo, Lelalai, Fatulia and Soba thousands more trees are being cultivated to enhance soil quality, reduce erosion, and restore biodiversity.

These interventions serve dual purposes: they shield roads and canals from landslides and flooding, and they offer long-term livelihood options through sustainable land use.

Why Baucau Matters

With its vast population, agricultural importance, and geographic vulnerability, Baucau plays a critical role in Timor-Leste’s climate and development journey. The region produces key staples, serves as a coastal and upland trade route, and houses communities that embody the resilience of the Timorese spirit. Supporting Baucau means securing a stronger national foundation. Through its partnership with the GCF, UNDP is not only building infrastructure in Baucauit is building confidence, dignity, and a path toward long-term climate resilience. Over 8,900 people are already benefiting from these interventions. As the projects progress, the people of Baucau are better prepared to adapt, thrive, and lead the charge toward a more resilient Timor-Leste.
