This Technology Transfer Advances Indonesia's

  • Nationally Determined Contribution to reduce risks on all development sectors by 2030 through local capacity strengthening, improved knowledge management, convergent policy on climate change adaptation, and disaster risks reduction, and application of adaptive technologies.  

Context

Jakarta is increasingly threatened by flooding due to a combination of rising sea levels, land subsidence, and higher river levels due to extreme weather. Government agencies need to identify areas at risk, as well as proven flood prevention policies and technologies for urban areas. 

Technology Request

The Jakarta Research Council, on behalf of the Provincial Government of Jakarta, requested support in building the capacity of stakeholders and decision makers with regard to flood management, as well as to evaluate the best technologies and methods for flood reduction and climate resiliant infrastructure in Jakarta. 

CTCN Response

  • Develop a high resolution hydrodynamic model for a study area in Jakarta that is capable of producing flood levels under differing climate and/or engineering scenarios.
  • Carry out a socio-cultural survey to capture the views of the local residents within the study area to the risks of flooding along with adaptation and mitigation options to alleviate these risks.
  • Enable local agencies to further develop the model to explore a wider range of scenarios.
  • Allow local authorities to take the findings from the technical assistance into account when formulating plans to provide a sustainable future for the area.
  • Identify future funding opportunities to further expand the utilisation of the hydrodynamic model.
  • Share lessons learned and facilitate South-South cooperation among Asian cities facing similar flooding challenges

Relevant Technologies and Approaches

Results

•    A hydrodynamic flood model was developed and tailored for Jakarta in the context of climate change.
•    Local capacity in high resolution hydrodynamic modelling and use of the model was increased through capacity building.
•    Resultant policy and planning recommendations were developed with the aim of reducing flood hazards, risk and vulnerability of affected populations, including socio-economic considerations.
•    A proposal for upscaling of the pilot was developed, potential funders identified, and funding meetings conducted. These resulted in anticipated financial support of USD 5 million through bilateral funding for upscaling the technological approach to other polder areas in Jakarta.

Long Term Results

  • Improved capacity of relevant government agencies to formulate policy and action plans to reduce flooding and support sustainable city planning in Jakarta.
  • Reduction in loss of life and property.
