Tropical peat decomposition under land-use change: adaptation to resources and conditions

Contemporary agriculture techniques on tropical peatlands is converting swamp forests from net carbon sinks to permanent massive net carbon sources. Of great concern is that none of the agricultural management methods applied to date have been shown to prevent the loss of peat, while science-based measures towards improved management has potential to minimise the rate of this peat loss. In
TROPDEC project, we will study peat C and N dynamics in decomposition processes by microbial community and activity analysis and monitoring greenhouse gases (GHG) produced at major land uses on tropical peat under management conditions. A key issue is to find how the extensive diversity of microbes is contributing to ecosystem functioning in the form of produced and in soil processes modified GHGs in specific conditions. Data derived from the project will consist GHG flux and GHG production rate data, enzyme activity data, sequenced DNA and RNA data collected from defined land use types and depths in peat profile, in real management and realistic
management conditions. Data will be organized and documented in easy to access way for further re-use.
