Election authorities in Chhattisgarh are carrying out a detailed survey of the tribal population taking shelter in Salwa Judum relief camps in Naxalite-infested Dantewada and Bijapur districts of Bastar region in the state. "We have asked the district collectors of Dantewada and Bijapur to carry out a detailed survey and find out which village the tribals belong to and whether their names figure in the electoral rolls in their respective areas," the state chief electoral officer Alok Shukla said. He told The Indian Express that once the basic data about the voters in the 23 relief camps spread over both the districts are available, a decision can be taken about the arrangements to be made to enable them to exercise their franchise in the Assembly elections scheduled to be held by the year end. "The options are open. As usual, polling stations can be set up in their respective villages or additional polling booths can be established at the relief camps," he said, adding that all would depend upon the "wish" of the voters in the relief camps. Shukla said the preparations of photo electoral rolls are in full swing throughout the state and its final publication would be done by August 30. He said, at present, the state has about 15 million voters and the average annual increase in the number of voters is about two per cent. According to official figures, as many as 56,675 people belonging to 459 villages in Maoist-infested south Bastar region have taken shelter in 23 relief camps set up by the state Government in Dantewada and Bijapur districts. All these relief camps are heavily guarded by the police and paramilitary forces in view of the incidents of Maoist attack on these camps. These tribals had deserted their native villages following the threat from Naxalites who had stepped up violence in the region following the launch of "Salwa Judum", an anti-Naxalite movement in the area in June 2005. Besides, a large number of people from these areas have also fled to neighbouring Andhra Pradesh over the past three years of armed conflict and bloodshed in south Bastar. Meanwhile, senior Congress leader and former chief minister Ajit Jogi said it would be better if the state's Assembly polls were held in phases, one separately in the Naxalite areas in view of the prevailing situation.
