Impacts depend on the scale of deployment, initial land use, bioenergy feedstock, climatic region and management

regime (high confidence).

0Bioenergy & The role of previous land use

7

Bioenergy crops on previous forest land (deforestation): large CO2 emissionsfrom loss of vegetation and soil carbon, loss of many ecosystem services

Bioenergy crops on grassland: effects are case-specific(depend on climate, type of vegetation and bioenergy crop)

Bioenergy crops on cropland: typically increases soil carbonand improves many ecosystem services

Bioenergy from forestry: case-specific effects that change over time (benefits are usually larger in the longer term), location,

management practice, and accounting
