abstract irregular extraction from agricultural wells around parishan lake, moreover fall of groundwater surface and water salty, would affect the level of lake water and move lake water into wells. in this study we have evaluated the externalities of extraction from agricultural wells around the lake. therefore feedback effect is considered between agricultural activity around the lake and lev...

the agriculture of iran in addition to supplying domestic needs through agricultural exports in foreign trade contributed and exports products are more stable than other sectors. so, developing and expanding of exports can be a ground for iran in global markets. thus, the role of supportive policies in developing export to identify parameters affecting and suppling of agricultural exports of ir...

Abstract This paper analysed the effect of freshwater withdrawals and management on agricultural industrial sectors productivity in emerging market economies. The auto-regressive distributed lag model panel analyses were employed our estimations. Our result revealed that Brazil had better water use efficiency production with annual which contribute significantly positively to increase crop live...

according to concern the role of population on growth of economic, in this study proceeds the study of age structure population on growth of iran’s economic. to achieve the experimental results, period of 1966-2009 is selected and used of auto regressive distributed lag method to achieve the experimental results. independent variables include the per capita income, population growth rates of 64...

This paper analyses the relationship between Nitrous Oxide emissions, agricultural land use, and economic growth in Pakistan. Agriculture largely contributes to emissions. Hence, models of agriculture induced emissions are estimated addition total Estimated accommodate more flexible forms than those widely adopted testing Environmental Kuznets Curve. The Auto-Regressive Distributed Lag (ARDL) b...
