TAILIEUCHUNG - Global perspectives on first generation liquid biofuel production

Transport today is mostly sustained by liquid fossil fuels, despite the fact that the invention of the combustion engine started with biofuels. However, known environmental impacts and the instability of the fossil-fuel market have revived the status of biofuels. | R. FINK, S.

However, known environmental impacts and the instability of the fossil-fuel market have revived the status of biofuels. Some concerns have appeared regarding how emerging global climate changes will affect biofuels’ feedstock production, since agriculture is strongly dependent on climate variables. Therefore, numerical models were introduced to calculate how temperature and precipitation could affect crop production for biodiesel and bioethanol production. Furthermore, 4 scenarios projected by the Intergovernmental Panel on Climate Change were put into the calculations. The results show that temperature has significant impact on feedstock production in all cases (P . production will be particularly affected by climate change. Only soybean production will have some benefits from temperature increase (Figure). Discussion Since 1906, global air temperature has increased on average by °C ± , and for the next 2 decades it is expected that the air temperature will rise by about °C per decade (IPCC 2007). There have been numerous studies carried out to analyse the possible impacts of temperature change on crop productivity. These results indicated that the sector most affected by climate change and its R. FINK, S. MEDVED Table 4. Verification of CYP models. statistical parameters CYP .
