Abstract
This paper explores the potential for crop diversification in the Cauvery delta region of Tamil Nadu, an area where monocropping of paddy dominates, leading to vulnerability in the face of climatic challenges such as drought and floods. The study aims to analyse the current level of crop diversification, the factors influencing farmersâ awareness on diversification, and the reasons for its limited adoption. A stratified random sampling technique was employed to gather data from 600 farmers across different districts. Various analytical tools, including the Herfindahl Index, Simpson Index, Markov Chain Analysis, Logit Model, and Garrett Analysis were used to assess the degree of diversification, shifts in cropping patterns, factors determining awareness on crop diversification, and reasons for non-adoption of crop diversification. The results show that crop diversification is at very minimal level, with paddy retaining a stronghold in the cropping system, despite risks associated with water scarcity and labour shortages. Age, Education, participation in agricultural extension meetings, and experiences with labour and water scarcity significantly influence farmers awareness on diversification. However, the main barriers to adoption include lack of awareness on alternative crops and fear of production failure. The findings highlight the importance of tailored interventions by agricultural extension agencies to encourage diversification in this climate vulnerable region.
