The present study focuses on the awareness, perception and constraints of farmers about the GI tag of Kanyakumari Matti banana in Tamil Nadu state, India. Using data from 120 farmers across 3 blocks, socio-economic factors that impact GI awareness and perception are analysed through correlation and regression analyses. Constraints has been ranked by Garrett Ranking method. The result shows that the awareness is of a moderate nature, as 47.5% of farmers have medium awareness about GI. Out of 21 variables, 17 variables have been selected as per discussion with extension scientists. The variables like educational status, information-seeking behaviour and attitude towards GI were found to be significantly correlated with both awareness and perception. GI is perceived to be beneficial in protection of product origin and increased demand as per farmers (80.83%), whereas in the case of technological advancement, the percentage is 36.66% and unauthorized use prevention is 35%. Major constraints are lack of GI-specific training (71.86%) and market price fluctuation (98.26%). Targeted capacity building, infrastructure development and supportive policy are suggested for better adoption of GI and enhanced access to its market. These findings provide useful information for policymakers and stakeholders to design focused interventions that might enhance the economic benefit and sustainability of GI-certified agricultural produce.
