The Whanganui in New Zealand and the Ganges in India have both been declared legal persons - but to what end?

Presenter Manuela Saragosa asks David Gordon of the campaigning group International Rivers whether it isn't a little odd to give legal rights to a natural resource, and what they hope will come of it.

Meanwhile Rahul Tandon reports from India's holiest river, and Nick Thorpe from Europe's Danube, on some of the challenges facing these waterways.
