I definitely think that this idea is great in Africa, but how does it work here in the United States (or other 1st world country)? Maybe in the west, but elsewhere, not so much. The only thing that protects land from being developed is government involvement(ownership, payments for set-asides etc.). Private entities too often end up like the Nature Conservancy where a lot of people contribute and the rich who run it use the land as their private vacation spot. I don't know what the answer is, but maybe if we had more honor and less greed at high levels both inside and outside government, we might get somewhere.
