evidence: The residents of Susta, which comprises over 265 families, claim they are part of Ward 4 of Triveni Susta panchayat in Nawalparasi district of Nepal. "Susta has always been a part of Nepal and we are Nepali," said Aurangzeb Khan, vice-principal of the Shri Janta Dalit Primary School, the only school in Susa, whose painted wall reads Nawalparasi, Nepal. The people blame the changing course of the Gandak river, known as Narayani in Nepal, for the controversy around Susta. "Gandak forms the international boundary between Nepal and India [Bihar]. said Khan. "Earlier, Susta was on the right bank of the Gandak, which falls in Nepal. But, in due course of time, the river has changed its route and Susta now falls on the left bank of the Gandak, which is controlled by India. Should the changing course of a river change the nationality of local residents?" [...] In his 2006 paper, Shrestha claimed that the Gandak river was shifting east to west on the India-Nepal border. "Every time the Narayani [Gandak] river, which separates India on the east and Nepal on the west, cuts its banks on the west… the Nepalese territory gradually shifts inside India as encroachment. There are big floods and thousands of hectares of land shift towards the east of the river all at once," he wrote.
