Sobre La Plata en The Economist

How did this happen? And how will you stop it from happening again?

The answer to the first question seems to be a mix of unavoidable natural disaster, irresponsible urbanization and lack of necessary infrastructure.  No one disputes the intensity of the rains, which in some areas exceeded those that fell during Hurricane Sandy. The level of loss, however, points to a lack of preparedness.

In a radio interview Pablo Romanazzi, the head of the hydrology department at Argentina’s NationalUniversity, decried the “chaotic” development of the cities, claiming their residents never should have been allowed to settle at the natural drainage points for underground streams. Mr Romanazzi claimed that he had instructed La Plata officials on how to improve its storm-readiness after the city flooded in 2002 and 2008, to no avail. “We continue urbanizing the riverbeds. It’s crazy,” he said.
