Ecosystem-based adaptation at scale through Building with Nature - Towards resilient coasts in Indonesia

As of: November 2018

Objective and activities

Indonesian coasts suffer from erosion, caused by sea level rise, mangrove conversion for aquaculture and groundwater extraction. In some places kilometers of land are lost and this will exacerbate with climate change. Over 30 million people in Java alone are at risk. Hard structures like sea walls are ineffective in mud-coasts, expensive and unable to adapt to climate change. Furthermore, they fail to provide the economic, environmental and social services that healthy ecosystems offer. Using a Building with Nature approach the project combines ecosystem based solutions like mangrove restoration with engineering. We aim to mainstream the Building with Nature approach in coastal management across Indonesia for climate change adaptation and to implement a large pilot in Central Java to catalyse change.

State of implementation/results

  • Within the technical and socio-economical Building with Nature approach, 2.6 km permeable dams to enhance sedimentation were built.
  • Additionally, 1,16 km of rehabilitation measures had to be conducted as the permeable structures were damaged faster than anticipated.
  • Nonetheless, the observed sedimentation rates are good and the mangroves are recovering.
  • First steps to adjust and implement the biorights mechanism in the Demak setting were introduced.
  • In Banten Bay a small-scale demonstration site was established, which thanks to its strategic location close to Jakarta, is receiving many visitors.
