BHUBANESWAR: Jute cultivation in the State has come down to just 10,000 hectares (ha) from over 40,000 ha in the last 10 years. Participating in the national-level annual meeting of All India Network Project on Jute & Allied Fibres (AINPJAF) here on Tuesday, researchers said climate changes and lack of facilities for post-harvest management and marketability of the crop are the primary reasons behind the declining crop pattern. Currently, it is the small and marginal farmers - particularly in coastal areas - who are taking up jute cultivation.
