Fly-tipping can be a big issue for farmers who have to pay to clear any rubbish left on their land. Now, the Country Land and Business Association says there should be a "National Fly-Tipping Tsar" to take charge of the fight against the problem. The Government has recently announced new grants for councils and bigger fines for fly-tippers - will it be enough? As we've reported on this programme, sheep have been getting a bit of stick recently - accused of damaging habitats through overgrazing. But in Suffolk, the National Trust is using a small flock of rare breed sheep to improve habitats for wading birds at Orford Ness Nature Reserve. And we hear from a Welsh beef farmer who has been seeing how it's done in Chile. Presented by Charlotte Smith Produced for BBC Audio in Bristol by Heather Simons
