Abstract:
Climate change being one of the most dependent and devastating factors especially for agriculture and monsoon now a days became one unpredictable and more instances of crop loss due to heat wave occur. For the present study, a total of 5 blocks were purposely selected from a Salem district. A total of 200 samples were collected randomly from 20 villages. Pearson correlation coefficient was used to analyze the degree of association between production and climatic variables and Ricardian model was used to quantify economic impact of climatic variables on net income. The results of compound annual growth rate revealed that the positive compound growth rate of both maximum temperature and minimum temperature and negative growth rate of rainfall in the study area. The correlation analysis revealed the positive and negative association between climatic variables and production of different crops in Salem district. The regression analysis revealed that rainfall and gross cropped area had a positive impact on production of crops while the mean temperature had negative impact on production of crops in Salem district. Ricardian model revealed that both kharif season and rabi season rainfall had positive impact on net income of farmers while the maximum temperature had a detrimental effect on net income of farmers. It was observed that climatic variables had significant impact on production and net income of farmers in Salem district and hence crop planning of the district have to be programmed with due weightage to the climatic variables.
