“We know system diversity is one of the foundation stones to successful organic production and we have seen a demonstrated commitment from OSA to build that component of diversity relating to seed. I want to ensure my dollars to on-the-ground projects, a place where an emphasis to make an enduring difference is part of the mandate and where my dollars can be leveraged to build a stronger, healthier food system around the world.”
