Conflicts in the food, energy, land and water nexus

Shortage of one resource (land) can partly be compen­sated with another (water), but what happens if all of them are scarce? We see today that the market does not distribute scarce re­sources to those who are poor: if resources become scarcer the poor will be further disenfran­chised. In more extreme cases the rich will drive their cars with fuels made from food crops that the poor cannot afford to buy and lack the resources to produce themselves.
