India's southern city of Hyderabad is known as a high-tech hub — but its infrastructure is looking increasingly dated in an era of strengthening climate change impacts.

The city, home to offices of Microsoft and Google, this month saw its heaviest rainfall in a century, which left 70 dead and 5.7 billion rupees ($77 million) in damage to roads and drains, officials said.

In many cities in India, which find themselves increasingly caught between worsening droughts and deluges, urban planners have rarely considered growing climate risks when designing projects.
