With the purpose of knowing the effects of the weather phenomenon ENSO on the flora coverage between 10° and 40° off South America, a collaborative project between three GLOBE countries of the Region of Latin America and The Caribbean: Argentina, Peru and Uruguay, took place (have been carried out)
In each country, GLOBE teachers along with their secondary level students (Argentina), University level (Peru) and primary level (Uruguay) selected a study site and described land coverage, following GLOBE protocols of site selection, GPS, manual mapping of land coverage, digital mapping and biometrics. Subsequently with the help of satellite images the NVDI index for Niña, Niño and neutral years were determinate.
The results allowed better knowing of the fact that the weather variability that The Niña brings has a negative impact over the study sited of Argentina and Peru, and a positive impact for Peru. This last country characterized because of having a major human influence in the vegetation management and the water level of the Lake that hosts, and in which the dynamic growth of vegetation majorly depends.
