Green house gas (GHG) emissions from croplands are some of the least well quantified and most uncertain ecosystem fluxes. Croplands play, however, a crucial role in not only food production but also in mitigating climate change. We invite talks that cover measurements and modelling of the major GHGs fluxes from croplands. Talks addressing uncertainty issues arising from management activities as well as modelling related issues like model initialisation are especially welcome. The session is also addressing up scaling of cropland GHG fluxes to continental or global scale. In relation to the up scaling part we invite contributions on mitigation and adaptation strategies in arable systems under the context of food and water security.
