The consequences of climate change in agriculture and its Relationship with Rice producers rent (Case study; Mazandaran province)

In this study, it was tried that by theoretically elaboration and designing a model in form of Ricardian model and using panel data approach based on Generalized Method of Moments (GMM) model, the effects of climate change on production and profit as a measure of rice producer rent within cities of Mazandaran province during the period 1990-2011. Results of this study showed that the climate variables have significantly non-linear impacts on Rice production and cultivation area rent. Within cities where cultivation temperature has been effective on farmers’ rent, Sari has the most negative rents (-5108220, Rial per hectare) than other cities and the Noshahr has least negative rent (-1601270, Rial per hectare). Enhancing spring and summer temperatures have positive effect on rent, and once it becomes less than critical value, rent would be negative. Due to the temperature in summer, the highest rent achieved in the Sari (154372, Rial per hectare) and the lowest was Noshahr with 6084 Rial per hectare. rent and by increasing this factor, rent would alleviate.
