The Indian Monsoon is of major socio-economic relevance for the densely populated areas of southern and south-eastern Asia. Climate models for South Asia indicate large variations in precipitation but little variation in temperature. Projections of fucture climate show large uncertainties, on the one hand due to the unknown reasons of certain abrupt changes in the Holocene and on the other hand with regard to potential regionally different impacts of changes in monsoon intensity. A strengthening of the monsoon since the 20th century has been observed in the marine record and probably will increase the precipition in large areas e.g. of northern India. This will result in more and larger scale natural catastrophes. On the other hand it is probable that the gradient of precipitation will change, with the consequence that semi-arid and arid areas are likely to experience water stress conditions. A regional study on temperature and precipitation changes will be conducted in respect of Ladakh located in the north-western Indian Himalaya. The projection of future climate will be developed with the aid of a high-resolution multiproxy inferred past temperature and precipitation record for the last 5.000 years obtained from the lake sediments of the Tso Kar basin.

印度季风对南亚和东南亚人口稠密地区具有重大的社会经济意义。南亚的气候模式显示，降水量变化很大，但温度变化很小。对气候特征的预测显示出很大的不确定性，一方面是由于全新世某些突变的原因尚不清楚，另一方面是由于季风强度变化的潜在区域差异影响。从海洋记录中可以观察到，自20世纪世纪以来，季风的加强可能会增加大面积地区的降水，例如印度北方。这将导致更多更大规模的自然灾害。另一方面，降水梯度可能会发生变化，结果是半干旱和干旱地区可能会出现缺水状况。将对位于印度喜马拉雅山西北部的拉达克进行一项关于温度和降水变化的区域研究。未来气候的预测将开发与高分辨率的多代理推断过去的温度和降水记录的援助，在过去的5.000年中获得的Tso Kar盆地的湖泊沉积物。
