‘Totally reliant on Mother Nature’: UK drought raises water security fears

London, United Kingdom – In a wheat field near High Wycombe in the rolling English countryside, Alex Nelms watched the harvest on his farm die in a matter of days.

His crop had looked strong until the first heatwave came in May, when temperatures surpassed 35 degrees Celsius (95 degrees Fahrenheit) just as his milling wheat entered its grain-fill phase, the critical weeks when the plant fattens its kernels.

“It just killed everything stone dead,” he told Al Jazeera. “Everything was finished really early, and when we were sort of full of optimism and hope, it was scuppered almost overnight.”

Nelms farms just over 2,000 acres (809 hectares) of arable land in south Buckinghamshire, on a business his grandparents founded in 1955. His uncle, who has worked the farm for more than 40 years, has just suffered the worst harvest of his career.

Last month, the Department for Environment, Food and Rural Affairs (Defra) said almost three-quarters of England, 71.3 percent, remained in drought. Rainfall in August reached just 34 percent of what would normally be expected by that point in the month, Defra said, and reservoir levels were 18.2 percentage points below where they should be for the time of year.

“We’re totally reliant on Mother Nature,” Nelms said, and nature did not deliver this year.

After a historically dry spring and a run of summer heatwaves, the farm is down roughly 1,000 tonnes on its average harvest, a shortfall of some $270,000 in revenue.

The farm, tucked in the Chiltern Hills, a steep, long ridge of white limestone rock, has no irrigation and never will.
