Debt-Swap

According to the BBC the other day, the US and Brazil just signed a "debt for nature" swap. The agreement will convert "$21m (£13.5m) of Brazilian debt into a fund to protect tropical ecosystems."

While I know that the details of the deal and how that money will be applied is the most important part of this agreement (and the part that we don't know about) - I was pleasantly surprised to learn that we're (being the US) are doing debt-forgiveness this way. Obviously, this system will work much less with a country that has no means of repaying their debt at all (since no money to repay = no money for a fund) but I guess in a case like Brazil's, where it's more about allocation and commitment, this makes a lot of sense. Lower debt burdens also mean lower interest payments, which could go a long way in conservation efforts.

Seems like a win-win to me. Does anyone know anything else about these type of programs?
