Given that we will have a severe drought this year, what sort of impact will water restrictions have on those people who have gardens and rely upon them for a substantial amount of their food? The question of whether suburbia can be salvaged in a post-peak oil age has been answered by various people - have those who claim it can be looked at the question of water? Without taking Divine Providence into account, What is the carrying capacity of California if these drought conditions are the norm for several decades or more? Are there too many people living in the Bay Area for it to be sustainable?
Would state/federal assistance and subsidies be given to all farmers and gardeners equally? Or would Industrial Ag be the main beneficiary, because the national welfare is at steak. (California produces much of the food that the rest of the country eats, after all.) What would be the response of state and local governments if more people had to resort to gardening in order to survive? (Though it is probably more likely that the on-going exodus from California would increase in size first.)
