The quality of China's overworked, polluted and artificially fertilised soil needs to be protected or the country could struggle to grow enough crops for the 300 million to 400 million people who will move from the countryside to the city over the next 30 years, a senior government adviser warned today.

"Fertile soil is being lost faster than it can be replenished making it much harder to grow crops around the world, according to a study by the University of Sydney.

The study, reported in The Daily Telegraph, claims bad soil mismanagement, climate change and rising populations are leading to a decline in suitable farming soil.

An estimated 75 billion tonnes of soil is lost annually with more than 80 per cent of the world's farming land "moderately or severely eroded", the report found.

Soil is being lost in China 57 times faster than it can be replaced through natural processes, in Europe 17 times faster and in America 10 times faster.

The study said all suitable farming soil could vanish within 60 years if quick action was not taken, leading to a global food crisis."

the latest fashion for dealing with global warming is to bring back charcoal. It has to be rebranded for modern consumers, of course, so it is now referred to as “biochar”. But there are those who think biochar may give humanity a new tool to attack the problem of global warming, by providing a convenient way of extracting CO2 from the atmosphere, burying it and improving the quality of the soil on the way
