Reframing Jakarta Urban Flood Risk: Community-based Socioeconomic Resilience for Sustainable Jakarta

Asia-Pacific’s youth face high flood risks, yet many in Jakarta remain disengaged by technical messaging, though they are vital for future resilience.

The project was designed to close the gap between flood risk knowledge and the people most affected—youth and vulnerable communities in Jakarta’s peri-urban areas. While floods are becoming increasingly complex, with 13% being compound events, awareness and preparedness remain strikingly low. Technical studies exist, but they are presented in formats that fail to resonate with younger generations, leaving them disengaged despite being highly exposed and the future decision-makers for resilience. At the same time, government planning often relies on static, present-day data, overlooking how the poorest households can lose up to 100% of their income capacity in a single flood, compared to only a fraction for wealthier families. The project addresses this twofold problem: making risk information accessible so communities, especially youth, can understand their vulnerabilities, and providing governments with adaptive pathways to embed into the NAPs for equitable resilience.

The project developed adaptive pathways to address Jakarta’s growing flood risks by linking physical flood modeling with socioeconomic resilience analysis. Using Deltares’ HydroMT SFINCS and FIAT, we calculated Expected Annual Damage (EAD) across residential, commercial, and industrial zones, then compared results in terms of asset and welfare losses. This approach highlighted how poorer households face disproportionate impacts, reframing resilience (youth, age, gender) as the ability to recover rather than just physical damage. The work was carried out during Hack4Resilient Jakarta 2025, where youth innovators, researchers, and community advocates collaborated to design solutions aligned with the vision of Resilient and Sustainable Jakarta 2045. I led the project contributing both technical expertise in flood risk modeling and policy framing, ensuring outputs could inform communities directly and be adopted by governments through the National Adaptation Plan.

The project is expected to empower underrepresented youth and vulnerable communities in Jakarta’s peri-urban areas by reframing flood risk knowledge in ways they can access and act on. Instead of technical reports, the pathways highlight the hard truth: poor households face up to 100% income loss from floods, while wealthier families lose far less. By making this disparity visible, the project equips communities to demand fairer recovery measures and strengthens youth engagement as future decision-makers. At the same time, adaptive pathways provide government actors with tools to move beyond static planning, embedding uncertainty and shifting risks into the National Adaptation Plan. The impact for youth is twofold: improved awareness of their unique vulnerability and stronger capacity to co-create resilience strategies. For communities, the outcome is prioritization in adaptation policies, ensuring those most at risk are not left behind in the vision of Resilient Jakarta 2045.

The biggest challenge was reframing flood risk planning from a technical, top-down process into one that is community-central. Existing bureaucracies favor sectoral, infrastructure-driven solutions, which often clashed with our focus on socioeconomic resilience and youth engagement. While government stakeholders emphasized present data and physical damage, we highlighted future uncertainty and household recovery capacity. This mismatch created resistance, as prioritizing vulnerable communities meant confronting inequality. We addressed it by translating technical models into socioeconomic terms, using visual adaptive pathways to show options over time, and framing outputs to complement—not replace—existing instruments. In doing so, we positioned communities as co-owners of resilience, while enabling governments to act as facilitators through the NAPs.
