Sustainability aspects of biofuels
it can become a constraint. Water shortage is predicted to become particularly acute for
sugarcane in India, and wheat or maize in Northern China. In Sub-Saharan Africa, biofuels
feedstock production at a larger scale would also require irrigation investment and large-scale
soil fertility improvement, i.e. higher levels of fertilizer application (Msangi et al.,2007).
Increasing biofuels production will also impact water quality due to the use of agrochemicals
and harmful substances produced in feedstock processing and conversion. To increase
biofuels' water consumption sustainability, its feedstock cultivation under irrigated conditions
should be discouraged (Ajanovic, 2010).
5. Conclusion
The global food production is affected by a number of factors: diets, population, energy
prices, and so far, biofuels have not significantly impacted the food production. Nevertheless,
