Enclosure would likely be the factor that resulted in less available farmland and more privatized farmland during the industrial revolution. Enclosure refers to the process of consolidating small strips of land into larger, privately owned fields, often through the use of legal mechanisms or physical barriers such as fences or walls. This process was driven by landowners seeking to increase agricultural productivity and profits, often at the expense of smaller, traditional farmers who lost access to common lands. As a result, less land was available for small scale farming, and more land became privately owned and controlled by wealthy landowners. Urbanization and migration may have also played a role in reducing available farmland, but enclosure was a key factor in the shift towards privatized land ownership during the industrial revolution.
