Environmental cost of agriculture, Farming technology, Seed potato industry

A new report claims a 40% tax on meat and dairy across the world would cut greenhouse emissions by a billion tonnes a year. A team from the Oxford Martin Programme on the Future of Food says agriculture contributes around a quarter of the harmful gases, and a tax would help to reduce consumption.

A team from Cambridge University has developed a device to make potato growing more environmentally friendly. The 'i-Crop Probe' helps save water by taking constant measurements in the field. Then using computer technology it tells farmers exactly when they need to irrigate and in what amounts. Trials indicate it's helped to produce potatoes using 50% less water.

Latest figures from the British Veterinary Association show more than half of farm vets were injured at work last year; Now one vet has even gone so far as to spend tens of thousands of pounds of her own money making her job - and that of her employees - safer. Sophie Aylett, who runs Meadows Farm Vets in Bromsgrove, has been repeatedly injured and says poor farming equipment is partly to blame - so she's bought her own.
