(free)How do we feed the world?
How do we water the world?
How do we do both whilst mitigating and adapting to climate change and transitioning away from fossil fuels?
Everything else is a sub-set
• The ‘Nitrate Timebomb’ (British Geological Survey)
• Nitrate fertiliser, most ‘disappears’ – there’s 20 years supply under our feet
• 20% of all imported phosphate – a critical material – ends up in WWTP• Dropping it out is simply not the right answer
• 91% of global GHG emissions are from fossil fuels
• 80% of the world’s sulphuric acid is from de-sulphurising fossil fuels
• 80% of produced sulphuric acid makes fertilisers
• and not a drop to drink…. • 56% gap between water supply and demand by 2030
