Estimated number of primary school gardens in the US

[Lydia Olivier]

Hello,

Where is the best place to find the estimated number of primary school gardens in the US?

It seems sources use different methodologies which makes it challenging. Or should I except it is linked to their own agendas (USDA, SlowFood, etc.)

Thank you.
