How can land-use modelling tools inform bioenergy policies?

Area of Science:

• Environmental Science
• Energy Policy
• Agricultural Economics

Background:

• Global targets for bioenergy aim to mitigate climate change, driving rapid sector development.
• Distinguishing effective bioenergy options from ineffective ones is crucial for energy security and greenhouse gas mitigation.
• Biofuel production pledges in Europe, the US, and Brazil indicate significant growth by 2020.

Purpose of the Study:

• To evaluate the impact of bioenergy production on land-use change (LUC).
• To assess the utility of land-use modeling in guiding bioenergy decision-making.
• To identify internalities and externalities of biofuel development scenarios.

Main Methods:

• Review of relevant data sources and land-use modeling approaches.
• Identification of controversies surrounding indirect land-use change (iLUC).
• Development of a framework for comprehensive bioenergy assessments.

Main Results:

• Bioenergy production presents opportunities for energy security, climate mitigation, and rural development.
• Environmental and social consequences are contingent upon feedstock choices and geographic location.
• Existing integrated assessment models often neglect biodiversity and detailed data on suitable lands for bioenergy.

Conclusions:

• Plant biomass management for energy must align with food, feed, fiber, timber, and environmental service management.
• Optimal bioenergy solutions require policies incentivizing integrated management of diverse resources with low inputs and high yields.
• Region-specific practices are needed to maximize bioenergy benefits before a global LUC analysis can be completed.
