What is\u00a0PeatlandN2O?<\/strong><\/h2>\n

The ground-breaking nature\u00a0of the\u00a0PeatlandN2O\u00a0(N2<\/sub>O Budgets in Peatlands \u2013 from Process to Ecosystem)\u00a0<\/strong>project\u00a0<\/strong>lies in the integrated use of a combination of innovative methods, yielding a pioneering synthesis and modeling of nitrous oxide fluxes (N2O) at various spatial scales,\u00a0<\/strong>linked to microbial processes. The Project will:<\/p>\n

  1. determine the role of rapidly changing environmental factors such as soil moisture, freeze-thaw, and canopy effectson N2<\/sub>O emission, particularly in hot spots and hot moments;<\/li>\n
  2. distinguish between and quantify key N2<\/sub>O production and consumption processes using labelled nitrogen, isotopologues, and microbiome structure;<\/span><\/li>\n
  3. integrate results of experiments and novel measurement techniques (automated chambers, stationary and mobile eddy covariance towers, canopy profile analysis) into the PEATN2O model<\/strong> of N<\/span>2<\/sub>O fluxes and related environmental factors to enable the prediction of hot spots and hot moments of N<\/span>2<\/sub>O emissions;<\/span><\/li>\n
  4. upgrade IPCC emission factors and suitable land-use strategies to mitigate N2<\/sub>O emissions in peatlands, also considering other greenhouse gases;<\/span><\/li>\n
  5. predict the global distribution of N2<\/sub>O emissions according to the land use and five climate change scenarios for a 100-year time horizon.<\/span><\/li>\n<\/ol>\n

    Why N2<\/sub>O & peatlands?<\/strong><\/h2>\n

    Nitrous oxide (N2<\/sub>O) is a powerful greenhouse gas and dangerous stratospheric O3<\/sub> depleting agent. N2<\/sub>O\u00a0climate warming potential is 265 times higher than CO2<\/sub>.\u00a0Drained nitrogen-rich peat soils are major source of N2<\/sub>O<\/strong> globally.\u00a0<\/strong>Climate extreme events may boost the emissions, but knowledge of their effect is scarce. N2<\/sub>O is a product of various soil processes, including denitrification, nitrification, and other less-studied mechanisms. Partitioning of N2<\/sub>O fluxes between all these different mechanisms is still a major challenge. Microbial processes are of particular importance for N2<\/sub>O budgets. The role of canopy and tree stems in N2<\/sub>O budgets is currently unknown. Novel flux measurement techniques implemented at different levels in combination with remote sensing methods can provide a solid basis for adequate estimation of long-term N2<\/sub>O fluxes in peatlands from local to the global scale.<\/p>\n
