Farmers, notably livestock farmers, are being pressured to do their bit to cut carbon emissions and tackle climate change. Rightly so with the Vegetarian Society claiming that emissions from livestock are responsible for almost 20 per cent of the world's greenhouse gas emissions. The NFU disputes this figure, putting it at closer to 10 per cent but even so, that's still a lot of pollution and even more warming.
Livestock farming provides benefits for wildlife and improves landscapes but it also means cows and sheep burping methane - a greenhouse gas that is far more potent than carbon dioxide. It involves the use of chemicals and imported animal foods while the transport of livestock and livestock products causes carbon emissions.
But we do need to eat, and we do need to eat protein, and vegan diets don't suit everyone. So what can we do to cut livestock emissions while continuing to eat what we need, retain the benefits of animals grazing the countryside and keep livestock farmers away from the dole queues?
Next week bureaucrats in Brussels will launch their 'health check' of Europe's Common Agricultural Policy. One proposal in the health check is to limit the amount of money that can be paid to a single farmer or landowner which could cut the CAP bill by millions of pounds. Another is to increase the amount of money being switched from subsidies to farmers to payments for measures that help farmland wildlife.
Because profits are low, livestock farming has become more intensive with larger herds on smaller areas. Environmental damage, such as habitat loss and water pollution, is more likely but unless farmers are rewarded for looking after the environment they will continue to farm in the same way. That's where the Health Check can help.
The EU is already throwing Є2 billion of 'surplus' CAP money at the controversial Galileo space programme and should not be allowed to give away any more. Instead, Europe's agriculture money should be used to pay more farmers to farm in a greener way. That means something to replace the benefits of set-aside and a significantly bigger pot for birds needing specialist help like cirl buntings, stone-curlews and corn buntings. Farming in this way would cut carbon emissions too.
The EU must grab the bull by the horns, reform the CAP into one fit for the 21st century and re-shape farming so that it provides enough food but not too much, helps tackle climate change and re-creates the spaces that wildlife once filled.
