Where I grew up there are next generation farmers, but less every generation. Equipment is bigger and smarter, one guy can farm a hell of a lot of ground so they do.
I just wished happy birthday to a friend from the olden days. He's still farming his place (I have a real hard time imagining the place with out him) and I don't know what his exit plan is. His daughter isn't interested, I know. He has a step daughter that just graduated HS (His first wife died) and she might be, though she was really successful in future business leaders in HS (her team took 2nd place in the nation).
He doesn't have a nephew or a cousins kid, either. I'll have to ask him.
It's all changed so much these days. Advancements in technology, corporations (and countries) buying out farms, climate change, financial pressures and the cost of doing business...It's not easy for the farmers here, and I assume the same elsewhere. Most have to diversify or die out. For instance, the introduction of different stock, dorper sheep as opposed to more traditional types...Different feeds also...We have *saltbush-fed lamb here...Makes use of a plant that grows wildly in certain areas and flavours the meat.

Just one example. I have mates that run different crops than twenty years ago, run stock or have added in eco-tourism just to make ends meet. But that doesn't negate the issue of future generations not wanting to be there.
Sorry, fairly long comment. (Hopefully your mate works out an exit plan. Sounds like the lass is a good option.)
