The next few decades are going to see some significant changes in global agriculture. Not only will current breadbaskets get worse and worse for farming, but growing water shortages will force significant changes in how we irrigate, and what crops we can grow. Fortunately, I think that agricultural problems will be some of the easier ones to solve, and I’m expecting that we’re going to see a lot more food grown in places like the Sundrop Farm in Port Augusta, AU.
Two things we know won’t be going away as the heat rises are sunlight and sea water. This style of farm has an effectively limitless supply of power and water, and while the 15,000 tonnes of tomatoes produced by Sundrop is a tiny, tiny portion of the total global tomato supply, I think farms like this are going to become increasingly common.
I also think that the more agriculture is shifted to controlled environments like this, the more secure the crops will be against pests and fungus. In general, it makes sense to me to integrate the clean-room agriculture techniques being explored elsewhere in the world to eliminate the need for pesticides or fungicides. The work being done in this area provides a real hope for a stable global food supply despite an unstable climate.
