JICA Indonesia shared insights on flood management and coastal conservation in International Conference on Infrastructure
2025.06.20
On June 12, 2025, Ms. Takeda Sachiko, Chief Representative of JICA Indonesia, spoke at The International Conference on Infrastructure 2025, delivering inspiring insights on building resilient urban infrastructure to protect both people and the planet particularly on flood control management and coastal protection aspect. Drawing from Japan’s experience with challenges like land subsidence in Tokyo—similar to Jakarta—she highlighted how policies and innovative engineering, such as improved water supply systems and strict enforcement of groundwater regulations could control the land subsidence.
Ms. Takeda also shared the efforts of JICA's activity on flood control projects across Indonesia that is currently ongoing, including river normalization and drainage improvements in the several cities, while introducing the idea of utilizing underground spaces for flood discharge channels in the highly urbanized economic area, a cutting-edge solution based on Japan’s experience, that we are also currently proposing integrated Flood Control Management to JABODETABEK Urban Areas.
When it comes to coastal protection, she emphasized a holistic approach harmonizing protection, utilization, and environmental conservation aspects. However, the proportion should be differentiated, while the structural measure on protection aspect should be prioritized on urban area, the harmonization can be more considered in regional area. This idea align as what JICA is currently doing on Bali Beaches coastal conservation with sand nourishment. Also, we are proposing new projects along Java’s north coast that harmonize these priorities to create sustainable and resilient coastal communities.
Further, Ms. Takeda explained how public-private collaboration have been in place in Yokohama’s Minato Mirai 21 model, a project aims to redevelop the port area located in the central part of Yokohama City and create a mixed-use urban area with functions such as commerce, business, culture, and residential living. Another critical feature of this project is focus on sustainable urban development through designs and infrastructure that incorporate disaster prevention, environmental conservation, ecological shoreline protection, energy conservation, and CO2 emissions reduction. The central and local government-initially led the coastal reclamation, land development, and basic facility construction. Once completed, the land readjustment had been performed by Urban Renaissance (UR), a public agency specialized in quality urban development and housing projects, which later attracted private sector investment. To close, Ms. Takeda highlighted that for the development projects that require careful consideration of disaster risk reduction, it is important to carefully examine to which extent public sector can entrust the private sector with responsibility on their participation.
JICA continues to support Indonesia towards a more sustainable and resilient country!
