NEW DELHI: The Border Security Force (BSF) has flagged concerns over increasing radicalisation of Muslim population in the border district of Jaisalmer in Rajasthan with rising prevalence of "Arab customs" even as Hindus and Muslims admit to a shrinkage in dialogue between the communities.A BSF study that examined demographic changes has found a departure from traditional Rajasthani culture in terms of personal grooming such as hairstyles and dress. The study also found a high 22-25 per cent growth rate in Muslim population as compared to 8-10 per cent of other communities. There is a rise in religiosity with higher attendance of children at mosques for more frequent namaz.While warning of radicalisation, the study says there is no evidence of any "anti-national" activity and there is no discernible soft corner for Pakistan among the minority population. Also, both communities have not had any problems so far and they conduct business and are cordial to each other, the BSF states.BSF study also talks about an increase in the membership of Hindu right-wing organisations, which are opposed by Muslims. "The activities of Hindu right-wing organisations have made Hindus in the village of Mohangarh, Nachna and Pokaharan more concerned about their religion. The membership in such organisations is increasing and they are extending their horizons at different spheres of religious activities ranging from training, monetary and communal support to education. However, no direct confrontation with other community has been noticed", the report says.The "study of demographic pattern in the border areas of Rajasthan and its security implications", notes that areas like Pokhran and Mohangarh of Jaisalmer have seen frequent visits of Muslim clerics, especially from Deoband, Uttar Pradesh. The clerics are reported to "preach fanaticism and (seek to) unite Muslims as a separate identity with feeling of paramountcy of religion".There is also an aggressive investment in land, which has now become a bone of contention for the Hindu community, BSF asserts. The growing communal divide is reflected in the "Hindu community believes that unbalanced rate of Muslim population increase is disturbing the communal harmony of their village."The BSF study also names a personage of Jaisalmer (name withheld), who often travels to Pakistan, has business interests there and has emerged as an influential political influence. "(The) involvement of Muslim population in anti-establishment activities and surfacing of anti-India sentiments on his call can't be ruled out..."It has recommended a check on activities of clerics, a task force comprising police, administration, intelligence and BSF, to assess any rise in the communal temperature.Asked about the report, BSF chief Rajnikant Mishra said that the force "regularly prepares these reports based on demographic, social, economic changes in border areas and shares it with sister agencies".BSF surveyed six villages — Mohangarh, Nachna, Bahla, Bharewala, Sam, Tanot and the town of Pokhran — in the border region of Jaisalmer district.
