Jammu and Kashmir was hit by heavy floods caused by torrential rains in September, which left at least 200 dead and thousands homeless.
Bachchan, while promoting a charity campaign 'HUM HAIN... Umeed-e-Kashmir' for the flood victims here, said, "As human beings and as Indians we need to do all that we can help our countrymen in need.
The plight of the people of Jammu and Kashmir has always been a matter of concern and the floods have only made it worse. "All that we do simply won't be enough to meet the various challenges facing the people, but every drop counts.
Hence we call on everyone in our country and from the world community to come forward and provide their support." Also present at the charity event was producer Mukesh
Bhatt, president of the Film and Television Producers Guild which is one of the initiators of the campaign.
Bhatt said the entertainment industry will do its bit for the state as it has been an integral part of Indian cinema. "The land of ethereal beauty and purity is in tatters, devastated by nature's fury.
The Indian entertainment industry has shared a wonderful symbiotic relationship with the land of Kashmir over the years and the time has come to repay the generosity and hospitality of Kashmiris in their time of strife.
We would like to support our Kashmiri brethren and contribute in our own humble way to relief and rehabilitation," he said.
Union Minister of State for Sports and Youth Affairs Sarbananda Sonowal also attended the event.
Bollywood celebrities like Aamir Khan, Ranbir Kapoor, Parineeti Chopra, Sonakshi Sinha and Sushant Singh Rajput will also show their solidarity for the cause by performing at a charity concert on October 18 at the Indira Gandhi Indoor Stadium here.
