For millennia, the Indus valley civilizations have learned how to manage the waters of the Indus river water system. However, climate change could bring about unforeseeable impacts to the growing population in the region and it could hinder the emerging needs of the energy-food-water nexus for short and long-term decision making.
In addition to that, changes in monsoon variability, and snow and glacier melt timing and amount may lead to extreme events, such as droughts over the Asian plains and flooding in the neighboring Himalayas.
Although global and regional climate models have advanced our knowledge on future changes in the climate system, there are still uncertainties and knowledge gap in representing the precipitation systems associated with the Asian summer monsoon and the winter and pre-monsoon western disturbances.
Lu Li and I have worked on this together with partners in India, the United States and Oslo. In our latest book chapter, we discuss the challenges in estimating the current and future hydrological cycle in the Hindu-Kush-Himalayan region in general, and the Indus river basin in particular, and why it is of utmost importance that we do so.
