Bioenergy is being pursued globally to decrease greenhouse gas emissions and provide a reliable source of renewable energy. To lessen conflicts with existing food/feed production, some bioenergy crops are bred to grow on marginal lands with minimal inputs. Many are concerned that new invasive species may be introduced as bioenergy crops. The authors of this paper encourage preemptive action: “Prevention [is] the best strategy to mitigate future invasions.”
The paper shows that the risk of invasion can most effectively be prevented through a life-cycle approach that adopts appropriate scientific and policy tools at each step in the production process:
- from crop selection to field production,
- during feedstock transport and storage, and
- during decommissioning.
The authors point out that “no single prescription exists for decreasing invasion risk associated with bioenergy crop production.” But this recommended “nested sieve” approach would help producers avoid the "kudzu effect." The CAST Commentary—"A Life-cycle Approach to Low-invasion Potential Bioenergy Production"—provides a clear, comprehensive framework to guide regulatory agencies in the selection and permitting of biofuel feedstocks.
