NEW laws will protect McLaren Vale and the Barossa Valley from urban sprawl through subdivision of land in the regions.
The laws protect land traditionally used for agriculture from being broken up for housing developments and shopping malls.
Planning Minister John Rau said the legislation had the multiple benefits of stopping urban sprawl by 'bookending' Adelaide, protecting the character of the two regions, and providing a valuable marketing tool for the regions' industries.
"We didn't want urban sprawl from Port Wakefield to Victor Harbor with its associated infrastructure problems," Mr Rau said.
"So when people like Jan Angus, d'Arry Osborn, Marg Lehman, Maggie Beer and the like were agitating to protect the character of the Barossa and McLaren Vale we could quickly see the dual benefits for Adelaide as well as those regions," he said.
"The State Government knows the importance of these regions for South Australia, particulary through tourism.
"We could not allow them to fall victim to the urban sprawl of a growing city."
State MP for Mawson, representing the McLaren Vale area, Leon Bignell likened the move to the protection given to the famous wine producing region Napa Valley in California and to Adelaide's parklands.
"Napa Valley would now be like Silicon Valley if it had not received protection," Mr Bignell said.
" In years to come people will look back and thank the people who had the vision to lobby government for this protection, just as they thank Col Light for the parklands."
d'Arry Osborn of d'Arenberg Wines said the protection gave him peace of mind, knowing the McLaren Vale will continue as a famous wine and tourism region close to Adelaide, rather than being swallowed up in Adelaide's suburban sprawl.
