As far as livestock, consider getting Ragnar Benson's "City and Suburban Survival." It was published in 1983, but the material is still mostly relevant.
He discusses the pros and cons of keeping ducks, goats, and so forth. He also mentions how small ponds can be stocked with fish, and the ins and outs of different kinds of crops.
My favorite part of his advice is how he deconstructs certain misconceptions and stereotypes . . . like how people stock seeds and fertilizers, but fail to stock pesticides, and how crop yields can suffer to the point of causing starvation because of irrational prejudice against the appropriate and conservative use of pesticides.

He also mentions the details about how to set up a slow speed diesel generator, which is preferred over other kinds, as they can last for 25 years of frequent use. Diesel fuel is also easier and safer to store than gasoline, and diesel lasts longer in storage. I'll add that there are kerosene refrigerators that can function perfectly fine with diesel fuel, and the Chinese tallow tree (Triadica sebifera) is an invasive pest that makes up a huge number of trees in the South and Midwest can be tapped for a biodiesel fuel that will work perfectly fine in a diesel generator, car, or kerosene fridge.
One tree can yield up to 120 gallons of fuel per year, and there are whole forests of them here in the States (they make up about 60% of all trees around Houston Texas, for example).
With your medical education . . . an understanding of the basic chemistry of extracting this fuel in a cheap, time-and-cost effective way would be trivial.
