The Effect of Range Management Projects on Pastures Efficiency (A Case Study in Khorasan Razavi)

If pastures become exploited correctly and also with reforestation and reformation, it would provide expected needs of agriculture section and also primary needs of raw materials in some part of industry. On the other hand, it becomes one of the safe bases of economy. So this study is about economic analyze of pastures assignment in framework of Lander grass projects in khorasan razavi province. In this order, by using two stage cluster sampling, at first amours 221 projects of pastures holding, 38 of them were selected from eleven cities of khorasan razavi province. Then randomized production function was estimated for these pastures. Basically, amounts of technical efficiency were calculated and also in this manner and rand cost function and its economic efficiency was earned. Results show that pasture holding projects in khorasan razavi cause to increasing in his production about twice (or duplicating his production in comparison with period before assignment). Also average amounts of technical efficiency of selected projects became 80 percent and for economic efficiency 35 percent, and finally about 44 percent in designation efficiency. Studying valid factors on inefficiency of pasture projects show that variables such as loan, pasture expanse, instructions and period of project performance have positive influence and variables such as; exploiter numbers have negative influence on technical efficiency of pastures.
