Speaking at the United Kingdom GovNet SDUK09 event Professor Sir John Beddington, chief scientific adviser to HM government, focussed on the availability of fresh water.

Fresh water available per head to the world population has reduced to around 25% of what it was in 1960. Already one third of the world population is facing water shortages. China, with ¼ of the world’s population and 10% of the world’s fresh water, was recently forced to seed clouds to address their drought. And to mitigate rising temperatures China announced that that it is going to build 59 new reservoirs to take the glacial melt in the Xinjiang province.

“California will not be able to produce agricultural products within 25 years”. That is according to American Steven Chu, a Noble Laureate in physics and an Obama appointment to the Department of Energy, regarding the problems of climate change and water shortage. Agriculture is accountable for about 70% of fresh water usage.

With the Arctic likely to be ice-free in the summer of 2030 we will experience a significant impact on climate change.
