Some of the key points from Julians speech included the fact there will be 9.2 billion people in the world by 2050, requiring food production to more than double by this time. However at the same time the primary resources required to produce food are becoming increasingly scarce. Considering we have already hit peak oil, peak water, peak arable land and peak phosphorous doubling food production is going to be more than just a challenge. Basically farmers will be expected to double the global food supply using half the water, on far less land and with increasingly depleted soils, without fossil fuels, with scarce and costly fertiliser and chemicals, under the hammer of climate change and reduced R&D spending.
No wonder everyone left scratching their heads!
