I found this website while on one of my Internet tangents. Their mission:
Food Systems Network NYC is a membership-based organization designed to foster communication and cultivate community amongst various stake holders and professionals working across the food system. Members gather monthly for Open Networking meetings to encourage collaboration; share information; discuss public policy; and promote opportunities for individuals to partner on specific projects.
Their website has a lot of different resources (including food-policy/security-related jobs) and is a way to connect food advocates together.
Check them out at www.foodsystemsnyc.org.
