Global trends suggest that increasing land pressures will require considerable care in managing biofuels expansion, in order to prevent loss of biodiversity, damage to ecosystem services and release of carbon from sensitive areas. For the assessment of bioenergy options it is pertinent to address first potential conflicts in relation to land resources. In this section, key drivers and analytical approaches associated with the allocation of land resources for bioenergy production are presented. An overview of land use for bioenergy systems is first provided, followed by a summary of the principles and assessment methods for determining the appropriate locations for bioenergy production.
