Actually, while I am not sure what region you are in, most ancient farmers tried to grow crops that were right for the climate (for example, if they were in a hot, dry climate, they grew crops that did not require a lot of water), and for other kinds of crops, they tried to locate near to a source of irrigation. Rivers were very important in ancient times-- some cultures even worshiped them. Also, even in ancient times, farmers understood the importance of tilling the soil and taking good care of their fields. Interestingly, farmers in Biblical times understood crop rotation-- every seven years, they changed to a different crop or did not use certain fields, to make sure the soil had a chance to regenerate. And while there were various insects (like locusts) that attacked the crops, we are told that farmers were still able to grow various grains and fruits.

Searching for productive unoccupied land.
The ancient name that means "black land" refers to Egypt. This name, "Kemet," was used by the ancient Egyptians to describe their fertile land along the Nile River, which contrasted with the surrounding desert.

For being a farmer there is no need to have your own land
It's when highly productive grains are introduced to an area causing the land to work harder. Working the land harder eventually leads to the deterioration of the soil, erosion, and the decreased productivity of the land as a whole. It's when a farmer uses up all land available because not much land is available to farm on.
No, desertification is turning productive land into desert.
