Bolivia has recently made 'TK headlines' due to the proposal of a new law, which apparently enshrines equal rights between humans and 'nature'. A summary of the recent law and its raison d'etre can be found in the Guardian here
The proposal of this law is said to be due in part to the prominence of members of the indigenous Aymara Indian community in Bolivia's democratically elected government. For instance, both the current President, Evo Morales, and the Foreign Minister, David Choquehuanca, are Aymara Indians. However, the details of the law have yet to be fully fleshed out and it is uncertain at this stage how 'nature' could be represented under the law. Nonethelss, it is possible that the law could provide a new, and highly original, way of discussing TK and indigenous rights, but until the details are fully published the proposal can perhaps be best seen as 'aspirational'.
