BIOFUELS AND FOOD SECURITY: CONFLICT OR COMPLEMENTARITY?

By Ignacy Sachs and - -
It makes no sense to single out biofuels as the scapegoat for high food costs without considering the effect of the spectacular rise in oil prices, writes Ignacy Sachs, honorary professor, School of Advanced Studies in Social Sciences, Paris and visiting fellow, Institute of Advanced Studies, University of Sao Paulo. Sachs writes in this article that we ought to strive for greater moderation and efficiency in energy consumption and take all the necessary steps to assure the complementarity between food and biofuels production. It should be possible to greatly increase biofuels output without encroaching on land used for food production or resorting to deforestation. Sachs calls for using waste and marginal land to grow robust oilseed plants; transforming into biofuels (including biogas) agricultural, forest, and domestic residues and moving as quickly as possible to second generation cellulosic biofuels; intensifying research on biodiversity, in particular on oilseed-producing tropical trees and on the third generation of biofuels (algae).

AFTER OIL: MODERN BIOCIVILISATION

By Ignacy Sachs and - -
We are at the threshold of the transition out of the oil and, hopefully, the fossil energy age, writes Ignacy Sachs, honourary professor at the School of Advanced Studies in Social Sciences, Paris, and visiting fellow, Institute of Advanced Studies, University of Sao Paulo. In this article, the author writes that this transition has already begun, prompted by the recent spectacular rise in the cost of oil and the recovery of food prices. To avoid the continued warming of the atmosphere, we must drastically modify our energy use by: altering lifestyles and patterns of consumption; improving energy efficiency; and substituting fossil fuels with renewable energy. We also ought to reopen discussions on a new cycle of rural development to avoid the blind alley of excessive and premature urbanisation. The two objectives could be reconciled by promoting modern biocivilisations, which rest on solar energy harnessed through photosynthesis and explore the multiple uses of biomass - food for humans, fodder for animals, green fertilisers, bioenergies, building materials, fibres, plastics and other products of green chemistry (chemurgy) turned out by biorefineries, pharmaceuticals, and cosmetics. Biofuels are only a component of a larger whole.
