That's true. If you don't own that land, you have no control over it. That's a known factor going into the deal. Same as renting a house or apartment; you might not have a place to live next year. No one expects it, but if the owner sells it, or raises the rent higher than you can afford, you're out. Same thing with hunting and fishing lands. One owner will allow you, the next may not.
About the only thing you can do to control it is to purchase the land yourself. And, that's more often than not, very hard or fiscally impossible to do. You're at the mercy of the owner.
What I like about the planned solar project west of us is that the land owners are leasing the property to the solar company, not selling it. So they retain it in their family. After X years, the solar company has the option to pull out (literally. they have to remove the equipment if they leave), or renew for more years. So it's a 20-30 year experiment to see if it's viable or not. While the solar installation sits there, the land rests. No tillage means no wind erosion and actually soil building. No fertilizers to runoff as corn and beans did. No water usage from irrigation, so the aquifer replenishes through rainfall. No fossil fuel usage for tilling or harvesting. That's a bunch of expenses the farmer won't incur, plus the time savings. They can just sit there and collect the rent if they want, but I'd guess most farmers can't sit for long, so they'll pick up jobs and collect double income.
We'll see how it goes.
