Alongside political parties, a group of non-political organisations is also preparing to "campaign" for the November 25 Assembly elections. Their campaign, confined to the Bastar region, will try to impress upon voters the need to defeat those associated with illgal tree felling in the past.Both Congress and BJP candidates will be targetted. The campaign will be chalked out at the two-day national workshop on "Tribals and Forests" from today at the Indian Institute of Forest Management (IIFM).
