Easter Island DeforestationDeforestation Easter Island
Easter Island's ancient inhabitants were not the cause of deforestation on the island.
The last 3,000 years of Easter Island Easter Island have been reconstructed by a collaborative effort of Spaniards. Her new insights show that the deforestation of the island was gradual and not simultaneous in all areas. Research indicates that deforestation has devastated Easter Island for more than a thousand years and affected the breakdown of its old population.
The Frontiers in Ecology and Evolution report from Agencia SINC found that the research teams at the Institute of Earth Sciences Jaume Almera (ICTJA -CSIC), the University of Barcelona (UB) and the Center for Environmental Research and Forestry Applications (CREAF) looked at Easter Island deforestation from a new angle and analysed the climate, environmental and culturality.
Until now, the assumption of the island's environmental and culture breakdown was made on the basis of partial analysis of traces of pollen recorded in lacustria, which showed the abrupt substitution of prairies for prairies hundreds of years before the Europeans arrived. However, the new report has succeeded in reconstructing what has been happening in the dateline without disruption over the last 3,000 years and finds that deforestation has indeed been gradual and not simultaneous throughout the island.
New findings show that serious drought has taken place during this phase, which could have had an important part to play in deforestation and the collapse of the island population. "This questions classic understandings of environmental and culturally degraded ecosystems that are exclusively human-induced. There is still much to study, but thanks to new information it seems that a long and progressive sequence of climate, environmental and culture changes has brought about the moment.
These new insights question all of the conventional beliefs about the Easter Island's past, especially the presence of a sharp environmental and social breakdown caused by the island's antique society," said Valentí Rull, an ICTJA-CSIC scientist and principal investigator of recent research.
