Biofuels could better aid climate change fight if grown on converted farmland
Aug. 24 (UPI) -- The promotion of biofuels as an eco-friendly replacement for traditional fossil fuels has been criticized by environmental groups. But research published Monday in the journal PNAS suggests biofuels can help mitigate climate change only as long as biofuel feedstock crops, like switchgrass, are grown on converted agricultural land. Advertisement The problem with biofuels is that their promotion by policy makers can trigger deforestation. If trees are felled to grow crops to make biofuels, the action can hinder the fight to curb greenhouse gas emissions and reverse climate change. To calculate the effects of biofuels on carbon storage potential, researchers used models to simulate the movement of carbon through an ecosystem under a variety of land use scenarios. Scientists...
