What are the world's best alternative crops with flood and drought in global climate crisis?

Question

To face with potential crops' lose that may cause shortage of regional food supply, any ideas about fast harvests: seaweeds, mussel, millet, mushroom, cassava root; etc. with yield, method and links.

Answer 1

Hmm, I would say anything that is low on the food chain and matures quickly - mushrooms, seafood, and plants like soybeans (although not necessarily "alternative"). Methods of growing our crops in a different fashion include hydroponic plant growth, which requires no soil and can be done indoors with UV grow-lights.
