What technologies could sustainably replace pesticides, without compromising on yield or quality? The Global Food Security (GFS) programme’s David O’Gorman reviews a recent GFS workshop on the topic.

What would happen if we could no longer use pesticides? Well, there would be significant yield losses, food price increases, greater food insecurity and potentially political unrest and instability. There may well be reduced ecological impacts, but with loss of yield would come expansion of agricultural land, with release of GHGs and loss of biodiversity.

We are heavily reliant on pesticides to maximise crop yields and put food on our tables. Even with the use of pesticides, a third of food (PDF) produced for human consumption is lost or wasted – what might the figure be with a dramatic increase in pre-harvest losses following reduced pesticide use?
