As part of our week looking at the global food crisis, we turn our attention to Northern Italy, where in some areas a state of emergency has been declared. Water levels in the River Po have hit record lows, and the largest farmers' union has warned that the drought could threaten more than 30% of agricultural produce. Italy is the EU’s biggest rice producer, and we hear from an agronomist working to make growing rice more sustainable. We report on how a huge engineering project has begun to remove an 18th century weir from the River Nidd in North Yorkshire, to restore the natural life of the river system in the area. And as scientists in Belgium look into the effect music might have on pigs, we hear from a farmer in Suffolk who says classical tunes help to calm his stock. Presented by Charlotte Smith and produced by Beatrice Fenton.
