I always understood that those who keep shmita would be provided for with larger than normal pre-shmita harvest. Recently, I was approached for charity for those that are keeping it. No one ever said that farmers would have to become charity cases to be taken care of. Is giving charity in this case allowed? If yes, why? Thank you.

Giving Tzedaka and assisting farmers who keep the Shmitta is a very important Mitzva. The Torah does say that Hashem will bless the farmers that they will not need to beg, but the situation nowadays is very difficult for the farmers and they need encouragement and sometimes also money to help them keep the Shmitta.
