Changes in how land is used can affect the local climate in a number of ways. The addition of irrigation can add moisture to the region, increasing the likelihood of summer rain and cooling temperatures. Changing the land surface by adding cover crops can also affect the climate by changing the way rainfall is absorbed and changing the albedo which controls how much sunlight is reflected back to space instead of being absorbed by the ground (which warms it up). Here is an interesting article from MassiveSci.com which describes some of the changes that are occurring in the Great Plains due to farming practices.
