I’d asked how his six-hectare Okanagan farm was faring amidst what’s shaping up to be the worst drought in B.C.’s history, expecting an answer that had something to do with water shortage. But Tumbach told me the drought wasn’t hitting his crop so directly; like most farms in the Okanagan, his irrigation water comes from a highland lake that isn’t in any immediate danger of running dry.

It’s the knock-on effects that are killing him, he explained. One in particular: as the surrounding landscape desiccates, irrigated farms become oases that draw pests desperate for moisture. This year an unprecedented grasshopper infestation has laid waste to Tumbach’s vegetable harvest. He estimates the bugs will cost him more than $50,000 this year, a crippling blow for any small farmer.
