The world’s large water infrastructure projects often result in geo-political flashpoints - Rana Mitter hears from Majed Akhter about problems from the US to Pakistan while Dustin Garrick outlines a water crisis that is also a crisis in governance and why new management of the Murray-Darling basin in Australia may provide hints about a way forward.
And aside from Romulus and Remus, what prompted the founding of Ancient Rome. Archaeologist Andrea Brock outlines her new research that shows the emergence of a new island at a special spot on the Tiber in the 7th century BC led to massive infrastructure projects and urban growth.
