Fears are rising for hundreds of villages stranded by flood waters in large areas of Nepal, Bangladesh and India.

‘This is the worst flooding that parts of South Asia have seen in decades. Entire communities have been cut off. The only way to get aid to some of these villages is by boat and many are running out of food,’ said Jagan Chapagain, Under Secretary General for Programmes and Operations, International Federation of Red Cross and Red Crescent Societies (IFRC), says a press release.

‘The situation is going from bad to worse. In Nepal, as waters finally recede, our teams are finding communities that have lost homes, identity documents – everything. In Bangladesh and India, the number of people affected is rising by the hour as waters rush south.’

Overall, more than 24 million people are believed affected by the flooding in the three countries, with more than 700 people thought dead. Over 1,800 Red Cross and Red Crescent volunteers are working alongside local authorities to prevent further deaths and help communities withstand and recover from the floods.

Clean water and sanitation are major priorities in each of the affected countries with increasing incidents of some diseases already being reported.

‘The floodwaters have become a breeding ground for deadly diseases such as diarrhoea and malaria. We fear that other diseases such as dengue and Japanese encephalitis are also on the rise,’ Chapagain said.

In low-lying Bangladesh, the Red Crescent has described the flooding as some of the worst the country has ever seen.

‘Floodwaters are sweeping from the north of Bangladesh to the centre, submerging whole villages. Many communities are isolated, with no access by land. Millions have been forced to camp on any patch of dry land they can find,’ said BMM Mozharul Huq, Secretary General, Bangladesh Red Crescent Society.

‘We are delivering aid, food, water and other vital supplies but this disaster is one of the biggest we have ever faced. We are appealing for global support,’ Mozharul Huq said.

IFRC is supporting Red Cross and Red Crescent operations in each of the affected countries.

In Nepal, IFRC and Nepal Red Cross are launching a global appeal for about 3.5 million Swiss francs to support 81,000 people living in the most seriously affected parts of the country. IFRC has provided a start-up loan of 500,000 Swiss francs to ensure that resources are immediately available.

In Bangladesh, IFRC and the Bangladesh Red Crescent expect to launch a similarly targeted appeal in the coming days.

In India, IFRC released 320,000 Swiss francs from its Disaster Relief Emergency Fund (DREF) at the end of July, with a second allocation expected to follow soon.

‘People across the region urgently need our help. But their needs are now so immense they will not be met without international support,’ said IFRC’s Chapagain.
