In the second phase, according to Nepal's finance minister, the country's government is planning to put in place temporary shelter. This would also include providing basics like food, water, electricity, and telecommunications, and “possibly “cash for work initiatives.””The minister highlighted the global aid, saying multilateral institutions including the World Bank and Asian Development Bank have committed funds for humanitarian needs. He said neighbouring countries including India and China had also provided supplies and financial assistance.“The World Bank has committed to siphon off at least 10% of its un-dispersed allocation for other projects to these humanitarian needs. So that will amount to about $160 million…Similarly, the Asian Development Bank has committed $5 million,” Wagle told Bloomberg.New Delhi has sent more than 10 tonnes of supplies including medicines, tents and solar lamps, which was followed by another 35 tons aboard an Indian Air Force heavy transport aircraft on Thursday.Also Read | Nepal floods, in visuals: A collapse 5,200m high, 170km of devastation, bodies swept up to India & a lake overflowingNepal businessman says ‘won’t be surprised' if rebuilding costs hit $5 billionWagle's remarks come after Nepal’s billionaire businessman Binod Chaudhary told Bloomberg News that he wouldn’t be surprised if rebuilding costs hit $5 billion.
