Os impactos socioambientais do fenômeno El Niño e La Niña na cidade de Campina Grande - Paraíba entre 1975 e 2015.

Abstract

The El Niño and La Niña phenomena have great influence over the climate on the tropics, causing changes on rainfall and temperature patterns. On Brazilian Northeast the El Niño acts facilitating the prolongation of the dry season, while La Niña favors the rainfall índices. Campina Grande, second largest city of Paraíba state with approximately 400 thousand habitants, tends to feel the impacts that extreme rains or droughts bring, since the entire population is affected. Based on these premises, this monography aims to analyze the socioenvironmental impacts that ENOS generated in Campina Grande – PB between 1975 and 2015 by the evaluation of rainfall data, comparison of these with the existing data on the period and intensity of the Niños and the verification of the impacts by the journalistic records of the time. The results showed that the poorest population in the city is one of the most affected by extreme events, although the entire population receives some kind of impact, as well as the understanding that the Niños are not the only or strongest implicators of the local climate.
