The scale of the challenge is epic. With only 30 seasons of planting and harvest left before the population could hit that 10 billion figure, it’s clear that agriculture as we know it has to change, if we are to have any hope of feeding the planet.
Creating robot farmers
Before you scream at your screen about robots taking our jobs, hear me out. Many farmers say that time in the field, sat in a tractor for hours, is not just repetitive and boring, but robs them of time they could be spending on other key jobs they need to do to manage their business.
Preserving precious dirt
One reason small, mobile robots could be good news for farming is that they can replace a lot of the work done by large conventional tractors. Ordinary tractors are heavy. When they roll across the field they compact the soil. That crushes the gaps inside, reducing the size of the pores that hold air and water. This compaction significantly affects the soil’s ability to hold onto water and so a crop’s ability to take that up, along with the nutrients.
Giving waste a second chance
One of the most shocking facts I learned is the sheer amount of good, edible food that gets wasted. According to the United Nations, “An estimated third of all food produced ends up rotting in the bins of consumers and retailers, or spoiling due to poor transportation and harvesting practices.”
Slowing the ageing process
We can’t yet turn back the clock but, at least in fruit, we can slow the dial.
The bananas I eat at home in the UK could have travelled from Ecuador, the Dominican Republic, Costa Rica or a field even further afield. To get to me they will have been picked green, perhaps spent 40 days on a boat, and then eventually ended up in the supermarket where, in order to be picked from the shelf, they have to be a perfect yellow, with no black spots or brown patches. That takes incredible, careful management to achieve.
Making smarter choices
Spending time with farmers, producers, retailers and consumers, I quickly saw how our current ways of growing, processing and selling food just aren’t scalable or sustainable.
The only way we can feed 10 billion people by 2050 is if the farming and food industries become much more sustainable. And that requires changes to the whole model of growing, processing, transporting, storing and selling. It means a lot of businesses and governments need to take action. But so too do we all.
