Biofuels and Development The potential for biofuels is particularly large in tropical countries, where crop yields are higher than in temperate regions; also land and labour costs are generally lower. With crude oil prices above US$ 0.40 per litre, biofuels are increasingly competitive with fossil-based fuels. Cost reduction, improved conversion efficiencies and upscaling can assist developing countries in supplying the commodity markets with biofuels at competitive prices. International agribusinesses look at biofuel production as an opportunity for market diversification alongside food-oriented commodities. Such investments can generate significant income for developing countries, but do not necessarily promote local income and development. Sustainability
