The climatic conditions during the beginning of the last 5000 years have been discussed, debated and documented from various parts of the Indian subcontinent, due to the human-climate interrelationship. In present study, we report a multiproxy dataset encompassing the widely used ~ geochemical and mineral magnetic proxies supported by radiocarbon and optical chronologies from the Banni Plains of the Rann of Kachchh, Western India. Our results support the earlier observations of prolonged wetter climatic condition synchronous with the mature phase of Harappan era which witnessed a short and intense arid condition at the terminal part of the Mature Harappan phase. The climate system dramatically fluctuated during the last five millennia from pulsating between relatively arid (4800 to 4400 yr BP, 3300 - 3000 yr BP and at 2400 yr BP) and relatively humid phases (> 4800 yr BP, 4000 - 3300 yr BP, 1900 - 1400 yr BP and 900 - 550 yr BP). The multiproxy dataset shows a gradual strengthening of the monsoonal conditions from the Banni Plains during the Late Harappan phase. Apart from this, the high sedimentation rate (> 1mm/yr) recorded from the Banni Plains, suggest it can be tapped as a robust archive to reconstruct multidecadal to centennial climatic events spanning the Holocene Epoch.

从印度西部 Kachchh 的班尼平原重建过去 5000 年的气候变率

由于人类与气候的相互关系，印度次大陆各个地区对过去 5000 年初期的气候条件进行了讨论、辩论和记录。在目前的研究中，我们报告了一个多代理数据集，其中包含广泛使用的地球化学和矿物磁性代理，这些代理由来自印度西部 Kachchh 兰恩班尼平原的放射性碳和光学年代学支持。我们的结果支持了早期对与哈拉帕时代成熟阶段同步的长期湿润气候条件的观察，哈拉帕时代成熟阶段的末期出现了短暂而强烈的干旱条件。在过去的五千年里，气候系统在相对干旱（4800 至 4400 年 BP，3300 - 3000 yr BP 和 2400 yr BP）和相对潮湿的阶段（> 4800 yr BP、4000 - 3300 yr BP、1900 - 1400 yr BP 和 900 - 550 yr BP）。多代理数据集显示，在哈拉帕晚期阶段，班尼平原的季风条件逐渐增强。除此之外，从班尼平原记录的高沉积率（> 1 毫米/年）表明它可以作为一个强大的档案来重建跨越全新世的几十年到百年的气候事件。
