A soil specialist from Washington says governments and policy makers can address longer term food security issues by using organic agriculture to reduce erosion and improve soil health.
David Montgomery from Washington University spoke at the annual organics conference in Hamilton last week.
He says soil is the most important and valuable resource and governments need to think about implementing policies now to protect it for future use.
Dr Montgomery says it is vital to promote low erosion agriculture and organic agriculture and it is important start planning for the transition to a post-petroleum world.
