"Technologies that improve the balance sheet and bring some work-life balance open the way to making farming a viable and attractive career choice again."

Small family farms are particularly at risk. For context, 97 percent of the 2.1 million farms in the United States alone are family-owned operations – defined by the USDA as any farm where the majority of the business is owned by the operator and individuals related to the operator through blood, marriage or adoption."

Already more than half of them are in the U.S. Department of Agriculture's "red zone" for profitability, meaning it won't take much to tip them into outright losses. The younger generations are leaving in droves, meaning that when existing farmers retire there's nobody to take over the family business. Some farms will be sold to larger competitors, others will simply shut down.

Tech is often seen as the enemy of traditional small business, with the likes of Amazon decimating high streets and Uber out-competing local taxis. But many of the entrepreneurs I work with come from rural communities and are deeply concerned about the knock-on effects that the loss of small farms will have on local retail and service businesses.

When I hear these entrepreneurs make their sales pitches, they talk about cost savings and resource-use efficiencies but what many of them are really selling is convenience. Farming has always been a 365-days-a-year business, with an endless cycle of trekking out to check on the weather, animal welfare and crops.

Now, as companies create systems that can provide that data on smartphones – right down to the level of the health of individual animals in some cases – the era of remote control farming is dawning.

To me, that's a great hope for stemming the flow of younger people away from family farms. Technologies that improve the balance sheet and bring some work-life balance open the way to making farming a viable and attractive career choice again. In some cases, they will allow small farmers to maintain a side-hustle, either another business or a job – and that could be the difference between making ends meet or not.

It's also important to remember that farmers are resilient and have been innovators since the beginning. One next-generation farmer I work with got so fed up with the time-consuming process of phoning around to potential buyers for his grain that he set up an online marketplace called FarmLead. He's recently opened an office in Chicago to expand in the U.S. northwest.

I admit that these technologies are significant investments and there's no escaping the fact that they will lead to some job losses. But we should look hard at reforming the $19-billion a year subsidy system – the bulk of which is currently swallowed up by larger producers – to better support small farmers making the switch.

If we can ease small farms over the financial bump of adopting new technologies, it would help put these vital parts of the rural economy back on a sustainable footing. I'd bet the farm on it.
