10. Biomass: beyond energy

11. Biomass: beyond greenhouse gases

13. Biomass: balancing land use, production and end use What types of trees and crops are best as carbon sink or for bioenergy and wood production? Can land be managed simultaneously as a carbon sink and for bioenergy and fibre production?
