Temperature Mediterranean Europe Climate Change in frequency of summer days in Europe, in the period 1976-1999 (days with temperatures above 25 C) Positive values indicate increase and negative values indicate decrease of annual summer days per decade. The circle size depicts the magnitude of change in summer days per decade. Source: http://www.eea.eu.int/

Energy crops vs. a standard crop rotation sunflower - wheat Carbon sink: + 200-440% (mainly in perennial crops) Energy Crops Fertilization (Phosphorus and Nitrogen): - 51-62% Organic Matter increases: + 50-75%. Pesticides: - 80-90%. Source: Bonari et al.

Conclusions Bioenergy crops show many environmental advantages and are, therefore, very sustainable. In Mediterranean areas, high climatic variations is associated with further projected variation due to future scenarios In this light, it is necessary to look for optimum combinations (economic, energetic and environmental) of species x cropping systems in each area
