Heavy monsoon rains in August and September 2017 triggered severe flooding over huge areas in Nepal, India and Bangladesh.
More than 41 million people were affected, with hundreds of thousands losing their homes, crops and livelihoods.
Over 1,200 people died and many more faced hunger and disease. Across the three countries, thousands of health facilities, roads and schools were destroyed.
The Red Cross and Red Crescent distributed food, clean drinking water, blankets and essential supplies to thousands of people. Mobile teams also provided medical care.
