I live in a valley in the foothills of San Diego. With appropriate time to establish a productive cycle, the land which is 20 acres, would work just fine until my well went dry. To mitigate that threat and adjust for the scarcity of quality topsoil, I would strategize away from field crops. However, my neighbor has grown oats on seasonal rainfall before. Without outside feed sources, live stock would pretty much have to be goats and chickens,but that is enough.

Fires are a threat but only because we are not allowed to clear the brush enough to mitigate the possibiity completely. I feel the house and family are safe, but a fire could destroy crops.
