A few years ago when I was working on a dairy farm in Canterbury, New Zealand, we experienced some of the strongest winds ever seen in the country, with gusts exceeding 200km/h in some places. The resulting damage was predictably catastrophic. Thousands of trees fell, causing widespread power outages. Roads were impassable and there was millions of dollars’ worth of damage done to property.

When it came to milking, there were huge complications, as, in many cases, power was not restored for up to eight days. Our farm was one of the lucky ones, as we had access to a generator, although we had to share it with eight other farms.
