Shortly after adopting this organisational structure , in 2009 , the National Dalit Watch ( NDW ) was set up . It followed from an extensive study conducted on the 2004 tsunami and later of massive flooding in Bihar ( 2007 – 08 ) , which NCDHR said highlighted caste-based discrimination in rescue programmes during disasters . Since its inception , various tools and methods have been designed to identify , expose and document caste-based discrimination and used the experiences of the people to influence disaster management guidelines by central government
