In India

* In Gujarat, Neera-producing societies have formed the Federation of Gujarat Neera And Tadpadarth Gramodyog Sangh. This organisation has set up a filtration plant that processes Neera to increase its shelf life. The Gujarat Neera and Tadpadarth Gramodyog Sangh, established in 1991, aims to improve living conditions of the workers engaged in the production of Neera. It is also trying to increase the production of neera in the state by planting more palm trees, and investing in the training of tapper-workers. *In
