Emissions reduction ideas discussed at MIF
Covering the Sahara desert in mirrors could significantly improve the earth's renewable energy output and subsequently cut its carbon dioxide emissions, it has been suggested.
That is one of several ideas to come out of the Manchester International Festival (MIF) this week, where proposals were collected for solutions to the problem of climate change.
Dr Gerry Wolff, an environmental expert, suggested that mirrors placed in the African desert could be used to focus sunlight for large-scale power generation.
"The major attractions of this is it's very clean - there's very little pollution," he said.
"You can store the electricity fairly cheaply, it's very quick to put up and can deliver power on demand. It's hard to think of any down sides."
Another of the ideas put forward was to encourage the food and agriculture sector to allow its animals to graze on the move, much like wildebeest.
According to Australian farmer Tony Lovell, this would allow large amounts of CO2 to be stored by natural grassland as it works to repair itself once the herd has moved on to a new pasture.
The winning ideas will be announced in a specially produced paper called the Manchester Report, which will be distributed in a special supplement with the Guardian later this month.http://www.mif.co.uk/events/the-manchester-report/
