Empowerment of coastal communities in cultivation and processing of Kappaphycus alvarezii—a case study at Vizhinjam village, Kerala, India

The Science & Society Division of Department of Science & Technology, Government of India sanctioned a project in 2005 under the Woman Scientist Program (DST WOS-B) with an objective to develop technologies for the cultivation of high-value seaweeds widely used for industrial purposes/human consumption with empowerment of the coastal communities in Kerala. The project was divided into two phases: an experimental/investigational phase and an extension phase. In the experimental phase, pilot-scale culture experiments were conducted to evaluate the possibility and feasibility of the cultivation of the red alga, Kappaphycus alvarezii, in the southwest coast of Kerala. Pilot-scale studies of seaweed culture were conducted in the shallow subtidal waters on the Vizhinjam Harbor area in two bamboo rafts tied with seeds of K. alvarezii (100 ± 1.20 g) following accepted culture and growth monitoring procedures. The first harvest was carried out after 45 days and the growth was nearly eight times the initial biomass (826 ± 2.80 g). A group of local fishermen were trained in the fabrication of culture rafts, implanting seed material, rearing the seedlings with periodical monitoring, harvesting, and post-harvest technologies like drying, sorting, packing, etc. as part of the pilot-scale study. The pilot-scale efforts showed good scope for the further expansion of the large-scale cultivation of K. alvarezii in the southwest coast of Kerala by imparting training and adopting fishermen families for their additional employment/alternative livelihood. Success in the pilot-scale cultivation led to the second phase of the project, the extension phase, which fulfilled the main objectives of the DST WOS-B programme. Vizhinjam Gramapanchayat (village), where the pilot-scale cultivation was carried out successfully and headed by a woman president, came forward to pool resources of the project to be implemented as a Model Seaweed Cultivation Programme. A training/workshop on “seaweed farming technology” was conducted and nearly 60 people were trained. Mangalam purusha sahaya sangham, a registered self-help group (SHG) of Vizhinjam, came forward to start the culture operations at Vizhinjam with technical backup from the DST-WOS-B Programme. Some seaweed entrepreneurs from inside and outside Kerala also came forward with a 100% buyback guarantee for the produce. Nationalised banks like the State Bank of India offered loans to trained SHGs for starting seaweed cultivation at commercial scale.
