like @kaidi says they have in Estonia, we also have Open Farms day in Norway. They don’t necessarily focus on selling products (the farmers decide themselves whether they will do this), but on informing and increasing knowledge about farming. I have to admit, I haven’t been visiting any of the farms in recent years myself, but remember well I did as a child, with my father - and memories that last for 30 years should probably be considered a success? The webpage (https://www.bondelaget.no/apengard/) seems to be in Norwegian only, but hopefully Google can provide an okay translation.
We also have Farmers Market, where the producers sell their products directly to the consumers. The producer is not necessarily a farmer, but someone who processes local raw food on a small scale. In the bigger cities, the markets show up regularly at squares, in parks etc, while in smaller cities, they attend festivals and other major events - or even small events focusing on food and farming.

At www.lokalmat.no (also in Norwegian only) local food producers may register to make their products available to purchasers for grocery stores. The local food awereness has increased in recent years, and now, many grocery stores offer a quite wide range of local products - or at least, products produced on a small scale not too far away. They are also hosting a “Local food school”, or courses for the producers, to build knowledge and networks: https://www.lokalmat.no/no/nyhetsarkiv/lokalmatskolen-er-i-gang
And of course, we have the REKO - local food network, which is one of our 25 cases. The purpose of a REKO-ring is to establish an online local food market, offering an effective, direct and easy way for local food producers and consumers. The interaction is direct, without any intermediaries. The local food market is co-created by producers, consumers and facilitators termed administrators through a process of facilitated interaction. As this is originally a Finnish consept, you may have heard of it before? Norwegian information is found at https://www.smabrukarlaget.no/norsk-bonde-og-smabrukarlag/matnyttig/lokalmatringer/aktive-reko-ringer/, and the Finnish founder also have a TED talk about it: https://www.youtube.com/watch?v=ETHa7MPEl1A
I’m not aware of measures to increase the use of local food in schools, but I believe that something has been done with local food in the elderly care, so I will look into it a little further.
Please let me know if you want me to gather more information about any of these measures, or if you want to get in touch with any of the local producers or organisations.
