Floating ‘B4’ boat labs will study the Brahmaputra river.

The Centre plans to safeguard the fast-eroding Majuli island (Asia’s largest riverine island) using research carried out on floating ‘B4’ boat labs along the Brahmaputra river. Majuli, the first island district of the country, was once 1200 square kilometres but due to excessive erosion has since shrunk to under 500 square kilometres.
