It wouldn't so much be a forced incarceration as an alternative to actual incarceration. In most area's vagrancy, squatting on public land, and most especially littering are all misdemeanor crimes. Currently violations of all these statues are not being enforced as it makes no sense to overflow the prisons for non-violent offenders or fine them an amount they cannot or will not pay. So with the work farm, they can can be convicted of the crime, get an alternative sentence to the farm which would be the equivalent of a work release, only when their sentence is completed, they have the option of staying there if they want to. It would arguable be a better quality of life then they would have living under the over passes and in city parks.
