Understanding water shortage

Where does the water come from, which reaches southeastern Brazil’s faucets? What explains its scarcity in drought periods? With no simple answer, the matter was treated in the cover story of the December 2014 issue.

We asked Antonio Donato Nobre, a researcher from the National Institute for Space Research (INPE), about the Amazon’s importance on the formation of flying rivers which carry water to faraway areas of Brazil and neighboring countries. What he said is central to engineer Monica Porto’s, from the USP Polytechnic School, discussion on the importance of rain to feed São Paulo water sources. A selection of these conversations, which took place in November 2014, is on this video.
