You do not need land, and you do not need to have farmed. What you need is membership — then you read the verification behind a farm, vote on whether its project goes ahead, and decide whether to take part.

Members read the verification behind a farm, vote on its proposal, then decide whether to take part.
Five things, in the order you meet them. None of them requires owning a farm.
Your Clan Pass — the ZIMOVERSE membership credential — is what lets you vote and take part. It carries a membership fee, and is issued once you are on the clan roll with a verified identity.
Every project is attached to a farm a coordinator has visited. The evidence is there before you decide.
Proposals are raised, seconded, argued and voted on. Nothing opens for participation before that finishes.
Choose which approved projects to join, and how much to commit. The minimum is set on each project.
Daily reports, coordinator visits and the harvest record stay attached to the project you joined.
Membership credential
The ZIMOVERSE membership credential. It identifies you as a Zimo Clan Federation member and carries two rights: a vote on proposals, including raising one, and the right to take part in a project the Clan has approved.
It carries a membership fee, set by the clan and paid when membership is approved. Beyond the fee it is earned rather than applied for: a member on the clan roll with a verified identity is issued one without having to ask. It can be withdrawn without removing somebody from the roll.
Taking part in an approved project is not a game and not a reward. Real funds go to a real farm for a real production cycle, and what you receive depends on what that farm produces and what it sells for. A cycle can return less than it cost.
That is ZIMOVERSE, and it is a different thing. ZIMOVERSE awards participation across the ecosystem — building a digital farm, completing activities, inviting people. No money is committed and nothing there funds a farm.
Membership comes through a cooperative in the MAISTRADE ecosystem. Once you have it, the Member App is where everything else happens.
