Samenvatting (EN)

One of the big issues and one of the main research topics today is global warming and the enhanced GHG effect. Greenhouse gases are needed to keep the heath on the earth s surface and create a stable temperature. However, the industrial revolution marks the beginning of a strong increase in greenhouse gases in the atmosphere and therefore an increase of temperature. Human activities like the use of fossil fuel, agriculture, industry and biomass burning have contributed to the increase of the GHG concentration in the atmosphere. Carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) are considered as the main anthropogenic greenhouse gases which are contributing to the global warming. The Kyoto Protocol (1997) represents an important first step in combating climate change. The Kyoto Protocol stipulates that the most developed countries must reduce emissions of six Greenhouse gases (CO2, CH4 and N2O and the fluorine compounds HFK, PFK and SF6) between 2008 and 2012 by an average of over 5% as compared to 1990 levels. The Netherlands committed, under the Kyoto Protocol, to reduce its annual GHG emissions by an average of 6% below the level of 1990 between 2008 and 2012. A considerable part of the total GHG emission in the Netherlands originates from the land surface. Due to past water level reductions, Dutch fen meadow ecosystems have over a long period been a strong net source of carbon dioxide as a result of increased peat oxidation, but reliable estimates of emissions of CO2, CH4 and N2O are still lacking. Burgerhart (2001) suggests that fen meadows can be turned into sinks of CO2 when water levels are increased. To what extent ground water level affects the emission of CO2, CH4 and N20 is not known yet. Where sources and sinks of Greenhouse gases can be found in this typical fen meadow landscape and what the driving variables for emission are is not yet clear.
