As the source of two-thirds of global GHG emissions, the energy sector will be pivotal in determining whether or not climate change goals are achieved. The International Energy Agency predicts that world energy demand will increase by one-third by 2035. If government policies promote the use of low-carbon energy sources—which includes biofuels—to 40 percent of total world energy use by 2030, then energy-related carbon dioxide emissions will still rise by 20 percent. This leaves the world on track for a long-term average temperature increase of 3.6°C.1 The need to reduce the dependence on fossil fuels to meet emissions targets outlined in climate change mandates and to improve energy security has already resulted in billions of dollars being spent worldwide to support the...

Global food production is having a hard time keeping up with demand, and trends suggest that it is only going to get more difficult.1 Global demand for food is growing as human and grazing animal populations increase, as more people are changing their diets to include more meat, and as more crops are used for biofuel production. On the other hand, it is getting more difficult to continuously increase annual agricultural yields as the downward pressure of soil erosion/degradation, aquifer depletion, and irrigation water supply complications due to melting glaciers begin to outpace technological advances in agricultural production.2 Many new problems have arisen as producers try to meet these challenging trends by squeezing ever more production from remaining...
