Putting aside water, the problem is not one of crop plants or 
distribution as such but of energy. Western agriculture is a very 
inefficient means of converting fossil fuels into food. Less 
sophisticated agriculture cannot meet the demand. Fossil fuels are 
finite, World population growth is still growing at about 
300,000/day. Malthus had it about right. See:-
