A scientist from the University of Cambridge came to the conclusion that the Nasca civilization was destroyed
because they eliminated its natural defense line; the huarangos forest, which used to protect them from the the ravages of “El Niño.”
The forest was a natural defense to El Niño floods.
David Beresford-Jones, from The McDonald Institute for Archaeological Research of Cambridge University, and other colleagues as well, arrived to this conclusion after studying the effects of El Niño in 1998 as a model to try to reproduce the impact of a similar phenomenon on this ancient civilization.
In 1998 there was a two-meter-high flood at modern city of Ica, and a projection with the help of the computers shows that “El Niño” happening sometime between year 500 or 600 a.C. could have had effects more catastrophic on the low Ica valley, one of the centers of the civilization.
However, the Nazcas could have survived that natural disaster, however had they not deforested the land for agricultural farming, according to this study.
