If you have seen the horrible plantations of oil palms on land that used to be virgin forest, you wouldn’t be so enthusiastic about land based biofuel production. I am now going for biodiesel production by mariculture of diatoms, which don’t take away vast areas meant for world FOOD production, and cost lots of scarce irrigation water and huge amounts of fertilizer, and destroy the habitats of endangered animals, Olaf Schuiling

Verdade Carlos I. Piña Luís Miguel Rosalino Highlights • Biodiversity impacts of biofuels crops expansion is generally related with usual agricultural impacts (i.e., land use change and agriculture intensification). • As agricultural landscapes are becoming more and more multifunctional, biofuels crops dominated landscapes might become good models for a sustainable agricultural development Abstract The use of biofuels can result on a decrease of greenhouse gas (GHG) emissions when compared to fossil fuels. However, the expansion of biofuels crops has been either based on direct or indirect displacement of natural ecosystems or on the use of degraded or marginal lands. The former results in direct habitat loss, whereas the later results in usual agricultural impacts (e.g., soil and biotic contamination and water eutrophication). However, in some circumstances biofuels crops can result on an increase in biodiversity compared to other agricultural crops. Agricultural zoning can mitigate the impacts of land use change (LUC), either direct (dLUC) or indirect (iLUC), whereas the use of wildlife-friendly techniques can mitigate the impacts of agriculture intensification. However, in both cases long-term biodiversity monitoring programs should be established in order to help the decision making process concerning the conflict between the expansion of biofuels crops and the conservation of biodiversity.
