Whatever happened to the Harappan nền văn minh?
New research sheds light on the sự biến mất of an ancient society
A
The Harappan Civilisation of ancient Pakistan and India phát triển mạnh 5,000 years ago, but a thousand years later their cities were abandoned. The Harappan Civilisation was a sophisticated Bronze Age society who built ‘megacities’ and traded internationally in xa xỉ craft products, and yet seemed to have left almost no depictions of themselves. But their lack of self-imagery – at a time when the Egyptians were carving and painting hình ảnh đại diện of themselves all over their temples – is only part of the mystery.

‘There is plenty of archaeological bằng chứng to tell us about the rise of the Harappan Civilisation, but relatively little about its fall,’ explains archaeologist Dr Cameron Petrie of the University of Cambridge. ‘As populations increased, cities were built that had great baths, craft workshops, palaces and halls bố trí in distinct sectors. Houses were sắp xếp in blocks, with wide main streets and narrow alleyways, and many had their own wells and drainage systems. It was very much a “thriving” civilisation.’ Then around 2100 BC, a thay đổi began. Streets went uncleaned, buildings started to be abandoned, and nghi lễ structures fell out of use. After their final sụp đổ, kết thúc, a millennium passed before really large-scale cities appeared once more in South Asia.

Some have claimed that major glacier-fed rivers changed their course, đáng kể affecting the water supply and agriculture; or that the cities could not cope with an increasing population, they exhausted their resource base, the trading economy broke down or they succumbed to invasion and conflict; and yet others that climate change caused an environmental change that affected food and water provision. ‘It is unlikely that there was a single cause for the suy giảm of the civilisation. But the fact is, until now, we have had little solid evidence from the area for most of the key elements,’ said Petrie. ‘A lot of the archaeological debate has really only been well-argued speculation.’

A research team led by Petrie, together with Dr Ravindanath Singh of Banaras Hindu University in India, found early in their điều tra, nghiên cứu that many of the archaeological sites were not where they were supposed to be, completely altering understanding of the way that this region was inhabited in the past. When they carried out a survey of how the larger area was settled in relation to sources of water, they found không chính xác, lỗi in the published geographic locations of ancient settlements ranging from several hundred metres to many kilometres. They realised that any attempts to use the existing data were likely to be về cơ bản flawed. Over the course of several seasons of fieldwork they carried out new surveys, finding an đáng ngạc nhiên 198 settlement sites that were previously unknown.

Now, research published by Dr Yama Dixit and Professor David Hodell, both from Cambridge’s Department of Earth Sciences, has provided the first rõ ràng evidence for climate change affecting the plains of north-western India, where hundreds of Harappan sites are known to have been situated. The researchers gathered shells of Melanoides tuberculate snails from the sediments of an ancient lake and used geochemical phép phân tích as a means of tracing the climate history of the region. ‘As today, the major source of water into the lake is likely to have been the summer gió mùa,’ says Dixit. ‘But we have observed that there was an abrupt change about 4,100 years ago, when the amount of sự bay hơi from the lake exceeded the rainfall – indicative of a drought.’ Hodell adds: ‘We estimate that the weakening of the Indian summer monsoon climate lasted about 200 years before phục hồi to the previous conditions, which we still see today.’

It has long been thought that other great Bronze Age civilisations also declined at a similar time, with a global-scale climate event being seen as the cause. While it is possible that these local-scale quá trình were linked, the real archaeological interest lies in understanding the impact of these larger-scale events on different environments and different populations. ‘Considering the rộng lớn area of the Harappan Civilisation with its variable weather systems,’ explains Singh, ‘it is essential that we obtain more climate data from areas close to the two great cities at Mohenjodaro and Harappa and also from the Indian Punjab.’

Petrie and Singh’s team is now examining archaeological records and trying to understand details of how people led their lives in the region five millennia ago. They are analysing grains cultivated at the time, and trying to tìm hiểu, tìm ra whether they were grown under extreme conditions of water stress, and whether they were adjusting the combinations of crops they were growing for different weather systems. They are also looking at whether the types of pottery used, and other aspects of their vật chất culture, were distinctive to specific regions or were more similar across larger areas. This gives us insight into the types of interactive networks that the population was involved in, and whether those changed.

Petrie believes that archaeologists are in a unique position to investigate how past societies responded to environmental and climatic change. ‘By investigating responses to environmental áp lực and threats, we can learn from the past to engage with the public, and the relevant governmental and administrative bodies, to be more proactive in issues such as the management and administration of water supply, the balance of urban and rural development, and the importance of preserving cultural heritage in the future.’
