Sure, we live in a globalized world, a global village. Recent events in the financial markets are somewhat painful reminders of that. But that doesn’t mean things are the same everywhere, or even going in the same direction. High(er) altitude farming is alive and well in Nepal, as Jeremy just noted. But on its way to extinction in England. Better irrigation is boosting rice yields in Cambodia. While karez wells are being abandoned in Afghanistan. That’s one reason why I don’t believe the genetic erosion meta-narrative. There is always an exception. And although you can sometimes see the world in a grain of sand, it’s better to look at the beach.
