چکیده:
This study aimed at investigating the relationship between economic growth and environmental degradation in agricultural sector among provinces of Iran. Thus, the value added generated by the agricultural sector was utilized as the index of economic growth and Carbon Dioxide emission from the agricultural sector as the environmental degradation index; then, a panel data of 24 provinces of the country over 1990 to 2014 was obtained from statistical center of Iran. The panel vector autoregressive (PVAR) model was employed to study the causal relationship between variables of the model; also, the panel autoregressive distributed lag (Panel ARDL) was used for estimating the model. Empirical results of the study revealed that there was a unidirectional relationship from agricultural value added and energy consumption intensity to agricultural Carbon Dioxide emission. In addition, the relationship between agricultural Carbon Dioxide emission and the agricultural growth was found N-shaped and statistically significant. Moreover, the results indicated that a relative increase in agricultural energy consumption intensity positively affected the Carbon Dioxide emission. As a result, future policies in the agricultural sector should involve appropriate plans for the conservation of environmental and natural resource of the country.

The Effect of Value Added and Energy Consumption Intensity on the Emission of Environmental Pollutants from the Agricultural Sector: Application of the Panel Autoregressive Distributed Lag (Panel ARDL) Model 2 Navid Kargar Dehbidi 1, Mohammad Hassan Tarazkar Received Date: 2017/11/09 Acceptance Date: 2018/10/07 Abstract The aim of the present research was to investigate the relationship between economic growth and environmental degradation in the agricultural sector of Iran's provinces.
Zafiriou and Azam (43) tested the existence of a relationship between agricultural sector growth and carbon dioxide emissions in the framework of the Environmental Kuznets Curve for three European countries, France, Portugal, and Spain, and the results indicated an inverted U-shaped relationship for all three countries in the long term; however, these results were not confirmed in the short term.
Research Methodology In the present research, in order to investigate the effect of energy consumption intensity and the value added of the agricultural sector on the amount of carbon dioxide emissions, the relationship model (1) was used (13, 38, 43).
In the present research, in order to examine the effect of energy consumption intensity and the value added of the agricultural sector on environmental quality, in this section, relationship (2) within the Panel ARDL framework has been used.
Causal relationship between the studied variables (PVAR approach) (Refer to page image) Source: Research findings As observed in Table 2, a unidirectional causal relationship exists from the indicators of agricultural sector value added and energy intensity towards carbon dioxide emissions.
