CTCN in Indonesia: Hydrodynamic modelling for flood reduction and climate resilient infrastructure development pathways in Jakarta

Publication date:

Land subsidence, sea level rise, and increasing precipitation will increase river flood risk in Jakarta from 2015 to 2030 by 180%. The Climate Technology Centre and Network (CTCN) is working with the Jakarta Research Council, the Agency for the Assessment and Application of Technology (BPPT), the Ministry of Environment and Forestry, the private sector and other stakeholders to develop a hydrodynamic modelling system that is now being used to map flooding causes and vulnerability in the city.

CTCN assistance:

• The development of a high resolution hydrodynamic model for a pilot project area in Jakarta that is capable of producing flood levels under differing climate and/or engineering scenarios;
• A series of recommendations aimed at local authorities to reduce flooding risks;
• Designing a strategy to attract financing for broader  hydrodynamic modelling and to take action on the recommendations.

During the workshop, which took place in Jakarta, the Indonesian officials shared their experience and a roadmap to expand the project with other major coastal cities in Asia, thus multiplying the potential effect of this flood risk-reduction initiative.
