A global food crisis?

The New York Times reports on a growing food crisis.

Consumption of the four staples that supply most human calories — wheat, rice, corn and soybeans — has outstripped production for much of the past decade, drawing once-large stockpiles down to worrisome levels. The imbalance between supply and demand has resulted in two huge spikes in international grain prices since 2007, with some grains more than doubling in cost…. the latest scientific research suggests that a previously discounted factor is helping to destabilize the food system: climate change.

The article ends on a hopeful if sobering note:

“We’ve doubled the world’s food production several times before in history, and now we have to do it one more time,” said Jonathan A. Foley, a researcher at the University of Minnesota. “The last doubling is the hardest. It is possible, but it’s not going to be easy.”

Water is of course one important component of this. However, food types (as described in the New York Times article) and garden layouts can overcome water shortages. Consider Geoff Lawton’s desert turned garden, as an example.

What role, then, might technology have in all this? One possibility is to help educate a new generation of gardeners, building on the increasing popularity of urban homesteading. A huge amount of knowledge once passed from parent to child must be made available to new gardeners, and online communities could help to supply that. Computer vision techniques could be used to help with the initial diagnosis the causes of plant diseases, while planning tools could help with garden layout and timings. Sensor networks could contribute information about microclimates (or help homesteaders to measure whether they had successfully created such climates), and build up information over time that could help guide seed planting schedules. The distribution of food (and labor) as crops become ready for harvest, sometimes in a surplus to need, could be facilitated by communication tools.

Some of these ideas may seem far fetched, but I am confident that technology has a role to play (some even exist already). After all, while I can’t claim this idea as my own, I recently discovered a robotic, solar-powered chicken coop for sale!

One response to “A global food crisis?

  1. I agree this point of view. However, I think governments and scientists must do more about the water as a global resource to put order in the food production.
    Robots doesn’t need water but wheat, rice, corn and soybeans production really do need this important resource.
    Excuse me if my English is not so good. I hope to read more about this topic in this blog. Thanks…
