More than half of Indonesia’s 4.2 million hectares of mangroves have been deforested or degraded over the past three decades.  Although rates of loss and degradation have slowed over recent years, both area and rate of mangrove forest conversion and degradation are the highest in the world. In order to maintain existing mangrove coverage, more than 50,000 ha of successful rehabilitation would have to be achieved per year. Yet anecdotally, failure ranges between 90-99%, with direct costs of >USD$13,000,000 and opportunity cost ranging from 0.5 billion to 10 billion USD/yr.The underlying drivers appear to stem from both a lack of understanding of the biophysical requirements of young mangroves and the lack of political or stakeholder will to restore converted mangrove areas.  From the perspective of the adaptive cycle, “rehabilitation capital,” (both ecological and social) has been degraded hampering mangrove forests’ ability to regenerate.

The aim of this PhD research is to identify and analyse mangrove forest landscape rehabilitation (MFLR) potential in Indonesia, through specific areas of opportunity representative of different landscapes, and to inform best practices for future national mangrove rehabilitation strategy. The research will evaluate current mangrove rehabilitation practices, conduct an assessment of biophysical, social and tenurial opportunity (resulting in rehabilitation opportunity maps), calculate the costs and benefits of rehabilitation and analyse the state of institutional readiness required to undertake landscape-scale rehabilitation. In order to achieve this a four step process adapted from the IUCN/WRI ROAM methodology will be used to evaluate rehabilitation opportunities and bottlenecks in 3 representative, degraded mangrove landscapes in Indonesia.

This research will be conducted in coordination with a sub-working group of the National Multi-stakeholder Mangrove Management Forum (KKMN) mandated by the Indonesian National Mangrove Management Strategy of 2012.  The results of this research are intended to both determine the viability of mangrove rehabilitation at the landscape level, while making recommendations for the reform of mangrove rehabilitation planning and practice in Indonesia.
