Danish farmers are facing a tax on methane from cattle, pigs and slurry. The charges will be based on how many animals a farmer has, and what sort of farming system they use. There will be money available for farmers to introduce technical solutions, such as covering up slurry storage, to reduce emissions. We visit a soft fruit farm in Kent which is part of a trial to generate electricity by draping lightweight, flexible solar panels over some polytunnels. And a study by researchers at the University of Cambridge has looked at the urban / rural divide in voting habits - and found what it called a gradient of disenchantment and distrust in democracy, that increases as it moves from urban centres through suburbs, towns, villages and out into open country.
