India 's biggest cities flood every monsoon season due to unseasonal rains, flash floods and droughts linked to extreme heat.

Roads collapse, drains overflow, infrastructure is overwhelmed and traffic grinds to a halt.

Experts blame rapid unplanned urbanisation, poor infrastructure and years of environmental neglect as root causes of this problem.

Each city faces unique challenges and factors such as geography, population and climate must be considered.

At least 30 people have been killed in India 's northeastern states after heavy rains triggered flooding and landslides.

Mangroves, which normally act like natural barriers against floods, have made things worse.

Human actions have made it worse: cutting down mangroves and building on floodplains where water is supposed to drain.
