I think the major problem with the rest of them is that they're government run. This proposal would be government owned, but run by private companies on contracts.
On paper they'd be incentivised, success would earn reward, failure would earn punishment.
How could that go wrong?
Government might not award contracts on merit. Measurement of kpi's may not be fair, private companies are by nature in it for the money.
Airtight contracts would be required to get them to commit to staff training and investing in the development side of things. Government generally does not do air tight contracts.
What else? How do you think it could go wrong? Need to do some risk management.
if you have a village where 80% of land is owned by private landowners and 20% of land is co-operative where do you think farm workers will want to work ?
rewards/incentives are easy to set. how do you handle failure ? lack of water causing drop in agricultural output. some mysterious pest destroying the crops. it is a lot trickier.
what you will find out is that some of the farmers who work on the 80% are better off handling the 20% state farms they know the agricultural profession. they know the labor conditions. they have economy of scale
