shack farming
n.— «Municipalities would be able to demolish the shack and thus continue our national effort to eradicate slums. The act also ends what is commonly called “shack farming,” which is when people invade land and build shacks for rental and thus create havens for criminals.» —“Housing Department Shackdweller Comments Evoke Strong Response” by Ndivhuwo Wa Ha Mbaya, Joel Bolnick, Marie Huchzermeyer, Rubin Phillip allAfrica.com Mar. 13, 2009.
