Abstract EN
Agricultural production and the availability of fresh water in Indian subcontinent critically depend on the monsoon rains.
Therefore it is vital to understand the causal mechanisms underlying the observed changes in the Indian monsoon in the past.
Paleomonsoon reconstructions show that the water discharge from the Ganges-Brahmaputra River system to the Bay of Bengal was maximum in the early to mid-Holocene; data from the Western Arabian Sea and Omanian speleothems indicate declining monsoon winds during the Holocene, whereas records from the South West Monsoon (SWM) precipitation dominated eastern Arabian Sea show higher runoff from the Western Ghats indicating gradually increasing monsoon precipitation during the Holocene.
Thus there exists considerable spatial variability in the monsoon in addition to the temporal variability that needs to be assessed systematically.
Here we discuss the available high resolution marine and terrestrial paleomonsoon records such as speleothems and pollen records of the SWM from important climatic regimes such as Western Arabian Sea, Eastern Arabian Sea, Bay of Bengal to assess what we have learnt from the past and what can be said about the future of water resources of the subcontinent in the context of the observed changes.
