UNHAS Visiting Delegation and Student Lectures

Hasanuddin University is one of the largest autonomous universities in Indonesia. It is located in Makassar, the capital of South Sulawesi province. A delegation from UNHAS in Sulawesi, with whom we have an MoU, are visiting The Fenner School. All are invited to watch two Fenner PhD students give short presentations on their research, and meet the delegates.

Talk 1: Timber Legality Verification System in Indonesian market chains - Depi Susilawati

The failure of state and non-state governance to combat illegal logging and the trade in illegally harvested timber triggered the government of Indonesia to invoke a hybrid forest governance system compliant with EU FLEGT regulations, the Indonesian Timber Legality Verification System (SVLK). The SVLK standard must be applied by all forest operators throughout the country. However, several studies have found that illegal activities related to timber production and trade continue. My research will investigate how SVLK is being implemented in Indonesian timber market chains. This study will apply a value chain framework in order to describe the architecture of SVLK in Indonesian market chains, explain the implementation of SVLK in contrasting Indonesian timber market chains, and explore the implications of these results for timber legality policy, instruments and implementation for Indonesia. This presentation reports some preliminary findings in three case studies of timber value chains originating from private forest in East Java, natural forests in East Kalimantan, and plantation forest in Sumatera. Results reveal the strengths and weaknesses of SVLK architecture in relation to each case study of value chains, variation in compliance practices, and points of legalization of non-compliant wood within the value chains.

About the Speaker

Depi is an Indonesian PhD scholar at Fenner School of Environment and Society, the Australian National University. She received the degree of Bachelor of Forestry at Gadjah Mada University, in 2007. Her first research topic was a phenomenology study which analysed the social institution regeneration related to community forest development in Indonesia. Afterwards, she completed a Master of Environmental Sciences at Wageningen University and Research Centre (WUR) in the Netherlands in 2013. Her Master thesis aimed at evaluating the implementation of Indonesian Timber Legality Assurance System (Indo-TLAS), commonly known as SVLK, in the verified community forests in Java Island. Before she started her PhD in February 2016, Depi has been working for Ministry of Environment and Forestry in Indonesia since 2009 as a young professional trainer. Her expertise was related to timber legality verification, forest certification, sustainable forest management, and forestry entrepreneurship development. She was involved in several international training projects which collaborated with MFP3, UK-AID, RECOFTC, GIZ and SNV Netherlands.

Talk 2: Pore-water Methane in Evolving Mangrove Forests: An Ecological Mangrove Rehabilitation in Tanakeke Island, South Sulawesi-Indonesia - Yaya Ulumuddin

Atmospheric carbon abatement through better management of coastal vegetated ecosystems is of interest in climate change mitigation. Mangroves are one of these ecosystems with a high carbon storage. However, the carbon cycle in mangrove ecosystems is complex and it is naturally variable, which may cause large uncertainties in its carbon sequestration potential. One of the reasons is due to methane production and export, which are not fully understood yet. Here, the current research aim was to understand CH4 production in mangrove rehabilitation site, where we did it by measuring dissolved CH4 in the pore-water. Thus, specific aims were set as a) development of pore-water CH4 measurement method; b) quantification of pore-water CH4 concentrations; and c) identification of the effect of mangrove regrowth on pore-water CH4 concentrations; and d) identification of the dominant methanogenic pathway in determining pore-water CH4 concentrations. Our study has established a pore-water extraction method which is simple and inexpensive being constructed using readily available PVC pipe and mesh. Also, this method offers artefact-free repeated extractions at a relatively high extraction rate (~500 mL hour-1). When combined with a sensitive Gas Chormatography or a gas measurement equipment, the CH4 measurement system in this study can be operated at high temporal resolution subject to labour constraints. Using this method, we measured pore-water CH4 concentrations ranging between 0.04 and 59.87 µmol L-1 which are supersaturated compared to its equilibrium state with the atmosphere. The variability of the pore-water CH4 showed a seasonal pattern which correlated with the successional stages. CH4 productions in this study site were generated through methyl compound users of methanogen microorganisms gaining carbon supplies from mangrove vegetation. The implication to climate change mitigation is that mangrove rehabilitations may contribute to CH4 emissions.

About the Speaker

Yaya is an Indonesian young researcher, working for Research Center for Oceanography (RCO), Indonesian Institute of Sciences. He completed his undergraduate degree in Biology at Bandung Institute Technology in 2004. His final project is carbon stock measurements in mountain forests of Mt. Papandayan, West java, Indonesia. Before finishing his Master in Natural Resources and Tropical Environmental Management at the same university in 2008, He was employed by RCO and got a job to do researches in mangrove ecosystem. Currently, he is in the last year of his journey of PhD degree, looking at a potential contribution of mangrove forest to methane emissions. In particular, his project aims to develop pore-water methane measurement, to collect empirical data of pore-water methane in relation to evolving mangrove forests in a rehabilitation mangrove site, and to understand the microbial process of methane production pathways.
