year drought wiped out Indus civilisation: IIT-Kharagpur

印度理工学院：900年的干旱摧毁了印度河流域的文明

KHARAGPUR: The Indus Valley civilisation was wiped out 4,350 years ago by a 900-year-long drought, scientists at the Indian Institute of Technology in Kharagpur (IIT-Kgp) have found. Evidence gathered during their study also put to rest the widely accepted theory that the said drought lasted for only about 200 years.

卡拉格普尔：印度理工学院的科学家们发现，4350年前印度河流域文明被一场长达900年的干旱彻底摧毁。他们在研究中收集的证据也结束了人们之前普遍认为的干旱只持续了大约200年的说法。

The study will be published in the prestigious Quaternary International Journal by Elsevier this month.

这项研究将于本月发表在著名的第四纪国际期刊《爱思维尔》上。

Researchers from the geology and geophysics department have been studying the monsoon’s variability for the past 5,000 years and have found that the rains played truant in the northwest Himalayas for 900 long years, drying up the source of water that fed the rivers along which the civilisation thrived. This eventually drove the otherwise hardy inhabitants towards the east and south, where rain conditions were better.

来自地质和地球物理学院的研究人员对过去5000年的雨季变化进行了研究，他们发现在喜马拉雅山脉西北部，有长达900年未曾有过雨水，滋养了繁荣文明的河流水源干涸了。最终那些吃苦耐劳的居民被迫迁往了降雨条件较好的东部和南部。

The IIT-Kgp team mapped a 5,000-year monsoon variability in the Tso Moriri Lake in Leh-Ladakh — which too was fed by the same glacial source — and identified periods that had continuous spells of good monsoon as well as phases when it was weak or nil.

印度理工学院的研究团队绘制了位于达拉克的莫里里湖过去5000年的雨季变化——这个湖的水源也是由同一个冰川提供的——并确定了持续雨季的周期以及雨季转弱或结束的时期。

“The study revealed that from 2,350 BC (4,350 years ago) till 1,450 BC, the monsoon had a major weakening effect over the zone where the civilisation flourished. A drought-like situation developed, forcing residents to abandon their settlements in search of greener pastures,” said Anil Kumar Gupta, the lead researcher and a senior faculty of geology at the institute.

该学院的首席研究员、地质学高级研究员阿尼尔·库马尔·古普塔说，“研究发现，从公元前2350年(4350年前)到公元前1450年，雨季对这个地区兴旺繁荣的人类文明产生了重大的削弱作用。干旱越来越严重，迫使居民放弃定居地寻找更宜居的地方。”

These displaced people gradually migrated towards the Ganga-Yamuna valley towards eastern and central UP; Bihar and Bengal in the east; MP, south of Vindhyachal and south Gujarat in the south, Gupta added.

古普塔说，这些流离失所的人逐渐迁北方邦东部和中部的恒河-亚穆纳河谷；东部的比哈尔邦和孟加拉;温迪亚恰尔南部，以及南部的的南古吉拉特邦。
