They call it the sea of olives, 70 million olive trees that stretch to the horizon in every direction in the province of Jaen in southern Spain. It's a spectacular landscape and yet, olives aside, the land is virtually dead, with scarcely a flower, bird or butterfly to be seen.

All this could be about to change following the remarkable success of a project that is raising new life from the dust of Andalucia.
