This land policy resulted in unemployment and impoverishment for many english farmers and laborers

The Inclosure Acts resulted in unemployment and impoverishment for many English farmers and laborers.

Explanation:

Inclosure Acts launched the policy of land fencing. It was the fruit of the eighteenth-century commercial context in England, and consisted of the transformation of the common lands of masters and servants from the old feudal-vassal relationship into pastures for sheep. Wool was, along with coal and iron, one of the pillars of English commercial expansion.  

The servants became a new class, the proletariat. Importantly, however, the servants not only migrated to urban areas under the Inclosure Acts but also to the English colonies in America.

There were small landowners who were agrarian but agriculture was for their own livelihood. With the permission of the government they were taken from their land, giving way to large landowners who were sheep and cotton producers who would supply the industry. Smallholders were then forced to leave their land and go to the cities, thus becoming cheap labor. Landowners raised sheep to produce wool and sell to the fabric industry, which at the time was performing well, the workers were expelled from their land, which caused the rural exodus, so these workers would go to the factories and become labor.  

The expansion of the Inclosure Acts encouraged the strengthening of a class of investors who exploited English property to drive the British economy into agrarian capitalism.
