Understanding the Knowledge Level of Farmers towards Climate Smart Agricultural Technologies in Agro-climatic Zones of Tamil Nadu, India

Aims: Although farmers experience various technical, technological, production, labor-related and marketing constraints to carry out agricultural activities, climate change acts as the root cause of several other constraints. Climate change consequences drastically reduce agricultural yield by affecting critical changes of crop growth and questions food and nutritional security; additionally it also imposes economic loss to the country. Hence, to ensure food and nutritional security for the growing population and to ensure sustainable income for the farming community, a farmer has to tackle the consequences of climate change by adoption of CSA technologies Farmer’s knowledge level towards any technology, determine its rate of adoption. Hence, this study aims to assess the knowledge level of farmers towards CSA technologies in Agro-climatic zones of Tamil Nadu.

Study design: Ex-post facto research design was employed in the study.

Place and Duration of Study: The study was carried out in seven agro-climatic zones of Tamil Nadu viz., Villupuram district of North Eastern Zone, Namakkal district of North Western Zone, Coimbatore district of Western Zone, Tiruvarur district of Cauvery Delta Zone, Ramanthapuram district of Southern Zone, Kanyakumari district of High Rainfall Zone and the Nilgiris district of the Hilly Zone of Tamil Nadu during 2022-2023.

Methodology: From each of Agro-climatic zones of Tamil Nadu, the vulnerable districts or the districts with NICRA project have been identified and the CSA technologies adopted by the farmers were documented. Thirty farmers who adopts CSA technologies from each agro-climatic zone were selected and interviewed personally to assess their knowledge level towards those technologies in a five point continuum ranging from ‘No knowledge’ (1), ‘Minimal knowledge’ (2), ‘Basic knowledge’ (3), ‘Adequate knowledge’ (4) and ‘Superior knowledge’ (5) respectively. The gathered responses were subjected to percentage analysis.

Findings: The findings revealed that Villupuram, Coimbatore and Tiruvarur farmers had superior knowledge on precision based nutrient management, Namakkal farmers had superior knowledge on use of additives and supplements in livestock feed, Ramanathapuram farmers had superior knowledge on utilization of weather based agro-advisory services, Kanyakumari farmers had superior knowledge on adoption of moisture conservation practices and Nilgiris farmers had superior knowledge on adoption of improved seed varieties and use of biofertilizers.

Conclusion: Villupuram, Coimbatore and Tiruvarur farmers had superior knowledge on precision based nutrient management; Namakkal farmers had superior knowledge on use of additives and supplements in livestock feed; Ramanathapuram farmers had superior knowledge on utilization of weather based agro-advisory services; Kanyakumari farmers had superior knowledge on adoption of moisture conservation practices and, The Nilgiris farmers had superior knowledge on adoption of improved seed varieties and use of biofertilizers. Thus, it can be concluded that farmers had superior knowledge on CSA technologies based on their perceived climatic change consequences and their accessibility to location specific technologies.
