 argue that a change from first generation to second generation energy crops like miscanthus is environmentally beneficial because of improved farm-scale biodiversity, predation and a net positive GHG mitigation effect.The benefits are primarily a consequence of low inputs and the longer management cycles associated with second generation (2G) crops.The authors identifies 293247 hectares of arable land and grassland in the UK (equivalent to 1.3% of the total land area) where both the economical and environmental consequences of planting miscanthus is seen as positive.
