- Negros Island â Following the abolition of the Negros Island Region in 2017 and the ongoing campaign of President Rodrigo Duterte for a shift of the Philippines's form of government to federalism, there are calls for the Negros island, consisting of Negros Occidental and Negros Oriental provinces, to be made into a single federal state or at least integrate the whole island in a larger single state if a federal form of government is adopted for the country. Negros Occidental 2nd District representative Rafael Leo Cueva said that the proposal is in line with the "One Island, One Region" movement which calls for the unification of the two provinces under a single region which began in the 1980s The region was reestablished in 2024.
