Controlling land use pursuant to that treaty is done with US officials: judges, zoning laws, and permits. Best you read up a little on how treaties are the foundation of US environmental laws that empower bureaucratic takings.
I know all about grabby bureaucrats, I live in Canada. With regards to the old revolutionary spirit, start identifying those jackboot creatures, 'crat scum and bootlicks who are in on this on a local level, the footsoldiers of the UN machine, and start working to undermine them in every possible way - no foot, no horse! Have loud public conversations about 'So and So', refuse them service in your establishments, shun them ostentatiously and let the world know why and what the stakes are, do everything you can to ostracize them. All kinds of social warfare tactics that they can't do anything about short of dropping all pretense and going total jackboot, which will destroy their cuddly public mask for good. If you already make it clear to people exactly who is hitting them in the pocketbook and in the property rights, the rest will be absolute poison to them.
