چکیده

یکی از چالش­های اساسی که تمامی جهان و از آن جمله کشور ما ایران با آن مواجه می­باشد، دستیابی به پایداری منابع است. با توجه به اهمیت استان فارس در بخش زراعی کشور، در این مطالعه وضعیت پایداری اقتصادی، زیست محیطی و اجتماعی زارعین در منطقه دشت کمین پاسارگاد، با استفاده از دو روش وزن­دهی درون­زای تحلیل مولفه اصلی و برون زای تحلیل سلسله مراتبی ارزیابی شده است. بدین منظور با استفاده از اطلاعات 150 نفر از کشاورزان منطقه در سال زراعی1394-1393، شاخص­های پایداری اقتصادی، اجتماعی و زیست­محیطی محاسبه گردید. در انتخاب شاخص­های پایداری نیز چارچوب تئوریکی سلسله مراتبی SAFE مورد استفاده قرار گرفت. در مقایسه شاخص پایداری ترکیبی به دو روش AHP و PCA مشخص شد که بین شاخص­های پایداری اقتصادی و اجتماعی در دو روش، از نظر آماری اختلاف معنی­دار وجود دارد. این در حالی است که شاخص­های پایداری زیست­محیطی مزارع، بر اساس روش­های AHP و PCA، تفاوت معنی­دار آماری ندارند. در مجموع تفاوت آماری معنی­داری بین شاخص­های پایداری ترکیبی بر اساس دو روش مذکور وجود ندارد. بر اساس نتایج به­دست آمده، به­کارگیری ابزارهای ترویجی و آموزشی و ارایه تسهیلات لازم شامل پرداخت وام به زارعین جهت اجرای عملیات خاکورزی حفاظتی، عملیات آبیاری تحت فشار و انجام آزمون خاک با هدف حفظ و بهبود کیفیت بر مبنای مدیریت مواد مغذی خاک پیشنهاد گردید.

چکیده [English]

Achieving the sustainability of resources is one of the main challenges of the whole world, including our country, Iran. According to the importance of Fars province in the agricultural sector, the economic, environmental and social sustainability of Pasargad plains farmers in the region are evaluated using the positive weighting method of principal component analysis and exogenous weighting method of hierarchical analysis methods. So, economic, environmental and social sustainability indicators were estimated according to the two mentioned weighting methods for 150 farmers of the region in 2014-2015. SAFE theoretical framework has been used to choose the sustainability indexes. Comparison of the two sustainability combination indicators of AHP and PCA show that there was a statistically significant difference between indexes of economic and social sustainability in two methods. But in the field of environmental sustainability indicators, there was no statistically significant difference based on AHP and PCA. Overall, there was no statistically significant difference between the two methods based on a combination of sustainability indicators. According to the results, it is suggested to provide extension and education tools and necessary facilities such as giving loans to the farmers in order to use minimum tillage, sprinkle irrigation systems and soil test to manage and improve the quality of soil nutrients.
