Increasing bioenergy production on arable land: Does the regional and local climate respond? Germany as a case study

摘要: The extent and magnitude of land cover change effect on local regional future climate during the vegetation period due to different forms bioenergy plants are quantified for extreme temperatures energy fluxes. Furthermore, we vary spatial plant allocation arable simulate alternative availability transpiration water mimic both rainfed agriculture irrigation. We perform simulations down 1 km scale 1970-1975 C20 2070-2075 A1B over Germany with Consortium Small-Scale Modeling in Climate Mode.
