For almost 40 years the Norwegian Forest and Landscape Institute (Norsk institutt for skog og landskap) has mapped vegetation in Norway. In total, just over 10 % of the country’s land area has been mapped, most of which is in the mountain regions. The resultant vegetation maps are the closest Norway has to an ecological map series. Many secondary map themes can be derived from the vegetation map and the digital format allows a wealth of both spatial and temporal GIS-analyses. Accordingly, there are many user groups and topics of interest. During 2009 the aim is to make the institute’s vegetation maps available to all via the Internet in a seamless database.

An overview of carbon dioxide (CO2) exchange and soil respiration measurements is given for representative Hungarian agroecosystems. We present results of long term atmosphere/biosphere CO2 exchange measurements carried out at the Hungarian tall tower site (Hegyhátsál). Tall tower net ecosystem exchange (NEE) measurements provided consistent estimates of landscape-wide carbon dioxide dynamics. During the period of 1997-2008 the region mostly behaved as a net CO2 sink on annual scale. Year-round NEE was in the range of  352±49 g C m 2 year-1 and 43±9 g C m-2 year-1 (negative values indicate uptake). The measurements are representative to a mixture of arable lands with small contribution from other biome types. Effects of different soil tillage methods - applied in two long term tillage experiments (Józsefmajor, Karcag) and in a peach orchard (Vác) - on soil CO2 emission are also introduced. Soil respiration rate highly depended on the depth of soil disturbance and on the date of the measurements; CO2 emissions measured immediately after tillage applications and during the vegetation period showed contradictory tendencies. Results obtained from a newly developed laboratory CO2 emission measurement method indicated strong coherences between soil carbon dioxide fluxes and soil water potential values.

Measurement of biosphere-atmosphere exchange of various greenhouse gases requires different techniques. In case of carbon dioxide the net ecosystem exchange (NEE) is usually measured by the eddy covariance method. In the lack of these measurements in forests the carbon dioxide uptake can be estimated by detecting changes in sequestrated carbon stocks or by using tree growth (dendrometric) measurements. The soil CO2, CH4 and N2O efflux/exchange rates can be determined using in situ chamber techniques, or laboratory incubation measurements. Static and dynamic, manual and automatic chamber methods, as well as photo acoustic, gas chromatography and infrared detections can be used for this purpose. This chapter gives a general overview of the approaches applied in studies presented in this book for evaluating the greenhouse gas exchange between the biosphere and atmosphere.
