Resumenhreatened by different drivers of soil degradation, from which soil erosion, contamination, salinization and loss of organic matter are highly relevant to the Mediterranean Region. Here, we present a summary of our experiences at evaluating the implications of soil contamination for the provision of two natural resources: pastures for livestock and lignocellulosic material for biofuel production. These experiences have been gathered during the monitoring of a trace-element contaminated area in SW Spain, affected by a mining accident in 1998. Soil contamination appeared to have a limited effect of pasture biomass production, but the accumulation of potentially toxic elements into aboveground biomass during the autumnal season might led to restrictions for grazing use during this season. The potential of certain native Mediterranean species for bionergy production in the contaminated lands was evaluated in field and mesocosm studies, which showed that some herbaceous species have a potential as energy crops, given their hability to colonize highly contaminated soils and to produce a high biomass with appreciable calorific value. The combination of controlled lowintensity grazing and bionergy crops could thus contribute to the re-valorisation of such degraded lands, where agricultural production for food purposes is often not allowed
