Estimation of farmers’ perception on productivity change dynamics of rice in coastal agro-ecosystem

Ecosystem begets, nurtures, sustains and transforms the live and live-forms. The present study has delved deeper into the congenital effect of climate change on productivity of rice in regards to coastal agro-ecosystem through estimation of agro-ecological and metrological variables. The present study also envisaged the perceptual and situation analysis of change dynamics of rice productivity by taking 19 independent variables and dependent variable, Change in Productivity (Y₅). The study has been based on a blend between participatory rural appraisal and a conventional multivariate statistical analysis including correlation coefficient, multiple regression analysis, path analysis and canonical covariate analysis. Almost every year, within a cohort of last 53 years, coastal agriculture of Odisha has experienced brunt of 40 years of drought, flood or cyclones. This has been reflected in the stagnating yield of food crops over the couple of decades, which has negated the positive impact of modern technology and fertilizer application in the operating farms. The result shows that, the variables like, Age (X₁), Family Size (X₃), Change in Consumption of Kerosene (X₆), Changing Interaction with Extension Agent (X₁₅), Changing Cropping Intensity (X₁₇), Change in average fertilizer dose (X₁₉) change pattern of watching television, listening to radio and change in education, all have been redeemed into a dependable estimator of change dynamics of productivity of rice with respect to climate change scenario.
