The floods come as India is still hesitant about a week of water crisis amid heavy droughts and heatwaves across the country that killed at least 137 people. Experts say the country has five years to tackle the severe water shortages caused by steadily decreasing groundwater supplies, or over 100 million people will be left without ready access to water.
In Afghanistan, drought has devastated traditional farming areas, forcing millions of people to move or hunger, while in Bangladesh severe monsoon floods have turned entire communities and disrupted vital roads. Especially risky are the hundreds of thousands of Rohinga refugees living in fragile, improvised camps on the border of Myanmar.
This is a sharp end to the climate crisis. What seems an urgent but still a problem for many developed countries is already killing people in parts of Asia and there is a new refugee crisis far worse than that that has hit Europe in recent years.
Agriculture in South Asia depends on the annual monsoon over the centuries. If the rain arrives late, as they did this year, they can cause widespread drought and water shortages. Since the end of the 19th century, scientists and government agencies have been trying to model and predict when the monsoon will come, a vital task in distributing aid and helping two billion people who depend on monsoon livelihoods. However, climate change makes this task increasingly difficult. According to a study in the journal Nature, the warming of the Indian Ocean, the increasing frequency of the meteorological phenomenon in El Nino, air pollution and the change in land use in the subcontinent has led to a constant reduction in precipitation, increasing the variability of monsoons, more difficult to get modeling accurately.
