Union Home Minister Amit Shah on Thursday said that information about population growth in border areas caused by “abnormal factors” such as alleged undocumented migration should be communicated from the local to the highest level as quicky as possible.“The Modi government is committed to curb unnatural demographic growth caused by abnormal factors with a ruthless approach,” Shah said at the Land Border Districts’ Superintendents of Police Conference in Delhi.He said that the Demography Mission had been set up to study changes to the population, identify factors contributing to such shifts and recommend measures to prevent them.“The primary cause of demographic changes in border areas is infiltration,” Shah said. “To make border security impenetrable, the Modi government has created a quadrangular security grid, transforming India’s approach from reactive to proactive.”The conference was attended by police officers from 119 border districts, director generals of police of border states, intelligence officials and representatives of forces guarding the border.“We are creating a robust system to make the country completely infiltration-free and to ensure that infiltration does not happen at all,” Shah said.He added that the meeting had given an institutional shape to a comprehensive approach towards border security and that a similar approach would be followed for coastal border security.Written by Sara Varghese.
