The article describes how possible mitigation of global climate change by CO2 absorption could change land use in the study area over the next 10 years. Two emerging modern carbo-sccnarios, forestation and grasslands, were outlined in a fine mosaic area of approximately 220 km(2) in Nove Hrady, Czech Republic. The forest scenario describes forestation for diminishing CO2 and represents a hypothetical situation in which society decided to pay for CO2 absorption in the form of subsidies or creating a market with CO, similar to tradeable emissions.The grassland scenario describes the establishment of grasslands for diminishing CO2. For this, the state could also decide to support grassland production so to mitigate the negative impact of CO2. In a workshop, 14 experts were asked to determine how much economic motivation would be required for them to plant grasslands or forests. The experts were offered three types of prices they could be hypothetically paid for producing grassland or forests to increase absorption of CO2. In a second part of the workshop, the experts estimated the proportion (not the area) of changes in land types under the forest and grassland scenarios.The experts estimation of changes in land-type proportion shows relatively great losses of arable land under both scenarios (up to 7%). The forest scenario would increase forests in the study area by up to 15%. The grassland scenario could be important for increasing biodiversity, because of the considerable increased number of patches (150), particularly of extensive grasslands. Scenario grassland seems to be more effective in producing a heterogeneous landscape mosaic, with all of its potential biodiversity consequences, compared to the forest scenario.One of the possible emerging roles of multifunctional agriculture should be also to maintain the landscape under carbo-scenarios in near future development.
