have you ever stayed on a farm?
My sister lives on a farm! They practice cultivating the animals, raising cows, etc.
my neighbors brother has a farm, they share fresh milk and eggs with us
It provided direct access to fresh veggies, fruits, and meats which improves food security and safety!
i would like to live on a farm and raise my own fruits, veggies. its so much healthier. 
Urban agriculture can also include aquaculture, agroforestry and horticulture.
