I have written earlier about the river Whanganui in New Zealand, that was declared a juridical person. (I am looking for follow-up info on what happens there.)

An attempt in India to give the revered rivers Ganges and Yamuna similar status has been turned down by India’s Supreme Court, to reverse a decision by the High Court of Uttarakhand State – where the rivers have their sources. (Both rivers are heavily polluted, and the hope was that with a clear legal status it would be easier to manage the protection of the rivers.)
