Objectives

The overall aim of PeatlandN2O is to comprehend N2O emissions from peatlands at soil microbial process, at ecosystem and global levels, with the specific Research Objectives (RO) to:

RO1: determine the role of rapidly changing environmental factors (soil moisture, freeze-thaw, canopy effects) on N2O emission, particularly in hot spots and hot moments;

RO2: distinguish between and quantify key N2O production and consumption processes using labelled nitrogen, isotopologues, and microbiome structure;

RO3: integrate results of experiments and novel measurement techniques (automated chambers, stationary and mobile eddy covariance towers, canopy profile analysis) into the PEATN2O model of N2O fluxes and related environmental factors to enable the prediction of hot spots and hot moments of N2O emissions;

RO4: upgrade IPCC emission factors and suitable land-use strategies to mitigate N2O emissions in peatlands, also considering other greenhouse gases and

RO5: predict the global distribution of N2O emissions according to the land-use and five climate change scenarios for a 100-year time horizon.
