Building with Nature in Indonesia: Restoring an eroding coastline and inspiring action at scale (2015-2021)
Aquaculture, fisheries and coastal agriculture
Coastal wetland conservation
Integrated delta management
This publication summarises the interventions and insights from a landscape scale implementation of the Building with Nature approach between 2015 and 2021 in Demak, illustrated with stunning pictures of the flagship and interviews with partners and communities. In this coastal district in Central Java, Indonesia that has been plagued by erosion, flooding and devastating land loss, we encouraged the natural regeneration of mangroves along 20 kilometres of coastline while simultaneously revitalising aquaculture. With this flagship project, Indonesia has become a pioneer in shifting to working with nature in designing water infrastructure solutions. And Indonesia has set the scene for upscaling Building with Nature elsewhere.
Restoring an eroding coastline
Our work involved techniques such as trapping mud behind temporary permeable structures to stabilise the coastline and allow mangroves to seed and grow and the introduction of environmentally friendly aquaculture practices. Besides engineering interventions, we engaged deeply with local communities, government agencies and knowledge institutes to address the root causes of coastal breakdown and deliver multiple benefits to coastal communities.
Inspiring action at scale
Beyond landscape restoration, we have supported upscaling elsewhere in Indonesia through training, knowledge exchange, institutional embedding and stimulating multi-disciplinary and multi-sectoral collaboration.
The knowledge, approaches and mechanisms used and lessons learned in Demak can support sound replication along the entire northern coast of Java, where millions of people are facing the loss of productive land.
Beyond that, we hope that our work inspires and helps enable the recovery of mangroves to protect communities and enhance local livelihoods for other Indonesian islands and for coastlines more widely in South and East Asia and globally.
Moreover, the Building with Nature approach can be mainstreamed in other types of landscapes. Check out the Building with Nature Asia initiative which aims to accelerate upscaling of Building with Nature in Asia.
