The climatic phenomenon in the altiplanic winter has ignited all the alarms in the north of the country. Heavy rain has affected the area that has caused aluvial and excessive growth of rivers. With this overflow hundreds of people are isolated. This phenomenon is concentrated in the regions of Arica and Parinacota, Antofagasta and Atacama.
The National Emergency Office (Onemi) has announced a red alert for the Arica and Parinata region. The authorities have indicated that the area is under constant surveillance and that, in fact, the Arica municipality has already organized four shelters for those affected by the emergency caused by the winter of this northern plan.
Why is this phenomenon so damaging? It is about winter winter being defined as a paradox, as the phenomenon usually occurs in our country in the summer: from December to March.
However, due to climate behavior, this seasonal sediment emerges as orthographic rain caused by the rise of humid air when faced with orographic obstacles such as the mountain, in this case the Andes Mountain Range.
The air masses that make this particular winter come from the Amazon region. All this phenomenon, added to the heat of the soil, causes precipitation.
More intense rain than other times
The question is why this phenomenon has caused so much damage this year if we, as a recurring phenomenon in the region in the summer, should be prepared.
We talked to Yao Szewkis, a meteorologist at the University of Valaparaja, who explained that on Wednesday and Thursday "the mountains of the mountains and the Andes were more intense than usual."
Nevertheless, Szewkis points out that "climate change alone is not enough, but obviously we have had to face strong consequences."
"The northern land is not sufficiently absorbed, so it is said that water" flows out. "" The specialist added that in the particular case that is happening now, "it should be prohibited to build in places where the river has ever passed."
It should be remembered that the full camp was influenced by the re-establishment of the flow. "Where there was a river, there will always be a chance that it will return, the water tends to go to these areas after 5, 10 or 15 years," said Spitz.
Build on an ecosystem
In this line, Elizabeth Wagemann, Professor of U. Mare's School of Architecture and Emergency, Reconstruction and Resistance Specialist after Natural Disasters; He added that "we know where the rivers are or where they were and they will return there." "So we have to work on the rules and measures that determine how and where to build," he explained.
As for Wagemann, "all activities, whether they are construction or planning, must take into account the ecosystem." "If the river has dried up, these rooms can be used in parks or other public places, but there is a risk of using them in housing constructions."
"All town planning, especially now with the climate change phenomenon, should be developed on the basis of the fact that we have to deal with nature," the academic concluded.
