A fundamental change has occurred in farming practice amongst sugar cane growers in the tropics of far north queensland. Where it was once standard practice to burn cane before harvest(defoliating green canes for easier harvest), tradition has been turned on its head and now almost no- one burns. However a 'green cane trash blanket' system has been developed with lot of advantages and few or no drawbacks.
There has been no official campaign or punitive sanctions imposed, no enticing financial incentives offered or charismatic environmental leadership - just a quiet technological revolution, based on the principles of the 'triple bottom line'(TBL). TBL has recently emerged into common usage amongst agriculturalists in Australia. Rather than attributing farmers actions as simple responses to economic stimuli('the bottom line') TBL is a framework that helps explain the complexity of factors that influence farmers to modify their practices. TBL suggests that farmers do indeed respond to money, but also to environmental concerns and further more to social considerations as well. This gives credit to farmers for being responsible steward of the land.
