I study mangrove ecosystem functions at Research Institute for the Environment and Livelihoods (RIEL), Charles Darwin University and Center for International Forestry Research (CIFOR). I have four years working experiences at CIFOR as Research Assistant, which mainly researched the role of Southeast Asian coastal mangrove ecosystems for sustainable climate adaptation and mitigation. I have published several peer-reviewed scientific papers and communicated research findings to the various international scientific conferences and workshops. I have special research interests in tropical mangrove ecology, blue carbon, and climate change mitigation and adaptation.
I work on three research projects as part of my current study with RIEL and CIFOR:
- The origin and accumulation rates of tropical mangrove belowground carbon sediment. The aim of this project is to quantify how much the sequestration rates of organic carbon in tropical mangrove sediments, and to identify the origin of that organic carbon whether from outside sources (e.g. sedimentation from upland landscape and marine inputs) or in-situ source—in this case plants net primary productivity. Both origin and sequestration rates will be only possibly researched by using stable isotopes and radionuclide sediment dating techniques. This study is located in West Papuan mangroves of Indonesia where is home for 15% of world’s remained intact mangroves, but under researched. This study provides scientifically sound information for climate change mitigation, specifically to understand factors determining blue carbon sequestration process in tropical mangrove ecosystems.
- The systematic review on carbon stocks and fluxes associated with land use change in global coastal mangrove forests. This study systematically reviews the impact of land use change to carbon losses from published studies in coastal mangroves throughout the world. This systematic review will provide a comprehensive scientific evidence for policymakers in line with current recognition of mangrove as high C reservoir coastal wetland ecosystem, and countries emission reduction target under Paris Agreement.
- Indonesian mangroves vulnerability to sea level rise. The overall goal of the study is focused on understanding mangrove surface accretion and elevation dynamics in the context of contemporary sea level rise and climate change adaptation. Field-based measurement stations have been installed and currently being monitored across Indonesian mangroves including West Papua, Northwest Java and North Sumatra in order to observe mangrove surface elevation change cost by sedimentation and belowground subsidence. The net surface elevation change data will provide us deeper understanding whether mangroves able to keep up or collapse toward sea level rise. This study is significantly important for future tropical coastal sustainability under rapid development and current global environmental change.
