What can we learn from Jakarta and Bekasi floods in March 2025? rapid assessment and policy recommendations to build urban resilience

Floods are common disasters experienced by many cities worldwide (Jonkman et al., 2024). Despite
many solutions, floods and their impacts have tremendously kept happening. Jakarta Metropolitan
Area (JMA), known as Jabodetabek Mega Urban Region, has had many flooding events in the past
(see Table 1 for details). Floods are closely related to problems with spatial planning, especially in
large catchment areas like Jabodetabek.

On 2 March 2025, extreme rainfall in the Bogor region, reaching 230 mm/day at Katulampa, triggered
a rapid rise in water levels (Badan Meteorologi, Klimatologi, dan Geofisika, 2025). By 9 PM, the
Katulampa Dam’s water level reached 210 cm, prompting a Siaga I warning (Badan Pengelolaan
Bencana Daerah Jakarta, 2025). The next day, March 3, continuous extreme rainfall triggered a flash
flood in Puncak, Bogor. This led to the overflow of major rivers, including Ciliwung, Cikeas, Cileungsi, Pesanggrahan, and other tributaries, causing widespread flooding across Jabodetabek.

Water depths ranged from 15 to 300 cm, severely affecting Jakarta and Bekasi (Badan Pengelolaan
Bencana Daerah Jakarta, 2025). As of March 5, floodwaters remained in Jakarta, Bekasi City, Bekasi
Regency, South Tangerang, Depok, Bogor Regency, and Bogor City, underscoring the prolonged
impact of this extreme event.

Given the scale and severity of the 2025 Jabodetabek flood, this study focuses on assessing its key
impacts on affected communities and infrastructure, as well as identifying necessary findings and key
recommendations to enhance urban resilience and mitigate future flood risks in Jabodetabek.
