Why when you plant a city on flood plain it becomes desert?

When you settle a city ON a good spot it reverts sometimes to only a 2 food producing place with no special extra stuff.

Was this done to balance the game so taking away production (+x food/prod./commerce) resources was easier?

No, ALL city tiles product 2 food. That's just what they do.
