پیشبینی تغییرات کاربری زمین و اولویت بندی مناطق ناپایدار زیست محیطی حوضه آبریز رودخانه هلیلرود
پیشبینی تغییر کاربری زمین میتواند اطلاعات مهمی را برای تصمیمسازی مدیریت زیست محیطی و برنامهریزی آینده مهیا سازد. اهداف اصلی این مطالعه ارزیابی تغییر کاربری زمین و پیشبینی تغییر برای سالهای 2030، 2042 و 2054 با استفاده از مدل زنجیره مارکف و اولویت بندی زیرحوضهها با بکارگیری فرایند تحلیل سلسله مراتبی فازی (FAHP) برای شناسایی مناطق ناپایدار زیست محیطی در آینده است. تغییرات کاربری زمین با استفاده از سنجش از راه دور و سامانه اطلاعات جغرافیایی در حوضه آبریز رودخانه هلیل رود بررسی شد. برای این منظور، از تصاویر لندست TM، ETM و OLI و الگوریتم طبقه بندی حداکثر راستنمایی برای سالهای 1994، 2006 و 2018 استفاده شد و پنج نوع کاربری زمین شامل مرتع متوسط، مرتع فقیر، زمین کشاورزی (زراعی-باغی)، پوشش آبی (شامل آب رودخانه، سد و تالاب) و سایر کاربریهای فاقد پوشش گیاهی (شامل رخنمون سنگی، کوه، خاک، مرتع بسیار فقیر و مناطق مسکونی) در حوضه مشخص شد. نتایج نشان داد که طی سالهای 2018-2054، مراتع متوسط، فقیر و پوشش آبی به زمینهای کشاورزی و فاقد پوشش گیاهی تغییر خواهند یافت، به گونهای که سهم پوشش مرتعی متوسط و فقیر به میزان 12/65 درصد کاهش خواهد یافت. همچنین، نتایج حاصل از بکارگیری رهیافت FAHP نشان داد که زیرحوضههای رودبار-جنوب و قلعه گنج در 36 سال آینده با شدیدترین بحرانهای زیست محیطی روبرو خواهند شد. نهایتاً اینکه در سال 2054، شرایط کاربری زمین و زیست محیطی تمامی زیرحوضهها، بحرانی پیشبینی میشود. بنابراین، اعمال سیاستهایی (از جمله مدیریت منابع آب) در جهت تغییر در روند تخریب زیست محیطی سطح حوضه پیشنهاد می شود.

اثرات تغییر اقلیم بر الگوی کشت محصولات زراعی (مورد مطالعه: دشت مشهد)
اقلیم و تغییرات آن در دهههای اخیر به یکی از مسائل مهم و مطرح جهانی و بهعنوان یکی از معضلات عمده زیست محیطی تبدیل شده است. بخش کشاورزی یکی از اولین بخشهایی است که تحت تأثیر این تغییرات قرار میگیرد؛ چراکه کشاورزان قادر نیستند شرایط اقلیمی را کنترل کنند؛ اما مدیریت و تغییر در عواملی چون رقم محصول و بهینهسازی الگوی کشت مطابق با اقلیم منطقه، میتواند آثار سوء این تغییر اقلیم را بر رشد و عملکرد محصولات کشاورزی کاهش دهد و در تولید پایدار مواد غذایی نقش بسزایی داشته باشد. لذا در این پژوهش، به بررسی اثرات ناشی از تغییر اقلیم بر الگوی کشت زراعی دشت مشهد پرداخته شده است. آمار و اطلاعات مورد نیاز پژوهش از طریق سازمان جهاد کشاورزی خراسان رضوی، سازمان هواشناسی و همچنین مصاحبه حضوری با کارشناسان کشاورزی و کشاورزان دشت مشهد جمعآوری گردیده است. نتایج حاصل از این پژوهش نشان میدهد که مقادیر بارندگی، دمای بیشینه و کمینهی فصلی روند افزایشی دارد و این تغییرات دارای اثر معنیداری بر عملکرد محصولات زراعی منطقه هستند. همچنین با درنظرگرفتن سناریوهای تغییرات اقلیم (تا سال 1410) در دوره کاشت هریک از محصولات مورد مطالعه، مقادیر سطح زیرکشت آنها تغییر یافته و سود ناخالص کشاورزان نسبت به سال پایه (1393) 6/1 درصد افزایش مییابد. در نهایت نتایج پژوهش حاکی از این است که بیشترین تغییرات در عملکرد بر اثر شرایط اقلیمی مربوط به محصولات گندم و جو میباشد؛ بنابراین لازم است تا سیاستگذاران به این موضوع توجه داشتهباشند تا ریسک تولید این محصولات را کاهش دهند و از کاهش تولید این محصولات استراتژیک جلوگیری نمایند.

ساماندهی کاربری اراضی بر اساس توان اکولوژیکی آن، نقش بسزایی در مدیریت محیط و جلوگیری از تخریب محیط زیست در راستای توسعه پایدار دارد. بر این اساس، هدف پژوهش حاضر مشخص کردن توان اکولوژیک کشاورزی و انتخاب مناسبترین مکانها برای اختصاص به این کاربری در شهرستان استهبان، واقع در استان فارس میباشد. برای سنجش دقیق توان اکولوژیک ناحیه مورد بررسی از روش توصیفی- تحلیلی استفاده شد. در این تحقیق فرآیند تصمیمگیری چند معیاره با بهرهگیری از سیستم اطلاعات جغرافیایی نقشی بسیار کاربردی دارد. با توجه به اینکه بخشی از شهرستان استهبان دارای مناطق حفاظت شده است و از آنجایی که در این مناطق امکان کشاورزی وجود ندارد، تحلیلها و محاسبات پژوهش حاضر بدون در نظرگیری مساحت قسمت یاد شده انجام گرفته است. نتایج نشان داد 77 درصد از مساحت اراضی شهرستان استهبان از نظر مکانگزینی کاربریها، در وضعیت ایدهآل قرار دارد و تنها 23 درصد باقیمانده از آن، تطبیق بین کاربری اراضی و توان اکولوژیکی این شهرستان را رعایت نکرده است. بر طبق نقشه توان اکولوژیک محدوده مورد مطالعه، نزدیک به 19 درصد اراضی شهرستان در طیف مناسب و بسیار مناسب از لحاظ کشاورزی هستند. همچنین، نتایج نشان داد قریب به 308 کیلومتر مربع از کاربری کشاورزی شهرستان استهبان با توان اکولوژیک آن مغایر است؛ اما این مقدار بسیار کمتر از 50 درصد میباشد و مساحت غالب شهرستان، دارای شرایط مساعدی از لحاظ محیط زیستی است. در مجموع با سیاستگذاری و توقف توسعه افقی شهر در اراضی کشاورزی پیرامون، توسعه میزان کشت و کاربری کشاورزی در جهت جنوب شرقی شهرستان، ایجاد صنایع تبدیلی وابسته به محصولات کشاورزی، ایجاد کارخانجات فرآوردههای انجیری مانند مرباسازی، ایجاد تشکلهای تولیدی انجیرکاران و حمایت و تقویت تشکلهای موجود، برگزاری برنامههای آموزشی برای کشاورزان در زمینه مدیریت و ذخیره آب و جلوگیری از مهاجرتهای بیرویه روستاییان به نواحی حاشیهای شهرها، میتوان به بهبود کشاورزی در مکانهای دارای توان کمک کرد و از تخریب بیشتر این قبیل اراضی جلوگیری شود.

شناسایی و تبیین پیشرانهای توسعه بازار محصولات کشاورزی ارگانیک
آینده کشاورزی ارگانیک به عنوان یکی از مصادیق رهیافتهای کشاورزی پایدار تا حد زیادی به تقاضای مصرفکنندگان و انگیزه آنها برای پرداخت قیمت بالاتر برای غذای ارگانیک وابسته است. از اینرو مقاله حاضر با به کارگیری روش تحقیق آمیخته اکتشافی به شناسایی پیشرانهای توسعه بازار محصولات کشاورزی ارگانیک پرداخته است. در بخش کیفی، با کمک تحلیل محتوای منابع و دادههای حاصل از 16 مصاحبه نیمهساختاریافته با صاحبنظران بازار ارگانیک، 29 پیشران در قالب شش گروه شناسایی شدند. در بخش کمی، به منظور تأیید پیشرانهای شناساییشده از روش تحلیل عاملی تأییدی مرتبه دوم استفاده شد. جامعه آماری این بخش مدیران، کارشناسان، تولید کنندگان و فروشندگان محصولات ارگانیک بودند که با کمک فرمول کوکران و روش نمونهگیری طبقهای با انتساب متناسب، 68 نفر از آنان انتخاب شدند. دادهها با استفاده از پرسشنامه مستخرج از بخش کیفی، گردآوری و با کمک نرمافزارهای SPSS22و Smart PLS3تجزیه و تحلیل شدند. مقادیر شاخص میانگین واریانس استخراجشده (AVE) برای هر یک از سازههای مدل، بیشتر از 5/0 و مقادیر ضریب پایایی ترکیبی (CR)، بیشتر از 7/0 بدست آمد که نشاندهنده عملکرد مناسب بخش اندازهگیری مدل است. بر اساس نتایج بدست آمده، عوامل فرهنگسازی و تبلیغات، تقویت کانالهای توزیع و فروش، حمایتهای مالی و اعتباری، بازرسی و نظارت، برنامههای آموزشی و ترویجی و تسهیلات گرفتن گواهی، لوگو و برندسازی به ترتیب اصلیترین و مهمترین پیشرانهای توسعه بازار محصولات ارگانیک هستند.

برنامهریزی راهبردی توسعه نظام ترویج تعاون در ایران
تحقیق کاربردی حاضر با رویکرد برنامهریزی راهبردی و با هدف تحلیل وضعیت و تدوین راهبردهای توسعه نظام ترویج تعاون کشور در دو مرحله اجرا شد. در مرحله نخست با مروری نظاممند، وضعیت ترویج تعاون در کشور واکاوی شد. بدین ترتیب، تعداد 44 عامل خارجی (18 مورد فرصتها و 26 مورد تهدیدها) و 35 عامل داخلی (17 مورد قوتها و 18 مورد ضعفها) شناسایی شدند. در مرحله دوم نسبت به تدوین یافتههای این مرحله در قالب یک پرسشنامه برای ارزیابی و تدوین راهبردها بر مبنای روش تحلیل SWOT و ماتریس کمی برنامهریزی راهبردی (QSPM) اقدام شد. یافتههای مرحله دوم نشان داد که، مجموع امتیازهای نهایی عوامل خارجی برای فعالیتهای ترویج تعاون 356/2 است. این امتیاز به این معنی است که بخش تعاون کشور نتوانسته است از فرصتها یا پتانسیلهای موجود، بهرهبرداری نماید و یا از بروز عوامل تهدیدزا، پیشگیری نماید. همچنین مجموع امتیازهای نهایی عوامل داخلی برای فعالیتهای ترویج تعاون 795/2 به دست آمد. این یافته نشان میدهد در حال حاضر نقطه قوت ترویج تعاون در حوزه عوامل و نیروهای داخلی تاثیرگذار است. راهبردهای قابل قبول در برنامهریزی توسعه نظام ترویج تعاون، با توجه به قرارگیری در خانه شماره 5 ماتریس داخلی و خارجی، راهبردهای محافظهکارانه است. با توجه به قوتهای مناسب ترویج تعاون میتوان راهبردهای تهاجمی را نیز مورد توجه قرار داد. در نهایت با استفاده از تکنیک QSPM جذابیت راهبردها تعیین شد.

بررسی تأثیر ویژگیهای ادراکشده کودهای زیستی بر مصرف آنها در بین کشاورزان (مورد مطالعه: روستای ینگیجه، شهرستان زنجان)
ویژگیهای ادراکشده نوآوری بهعنوان مؤلفههایی محسوب میشوند که پذیرش یک نوآوری را تحت تأثیر قرار میدهند. بر این اساس، پژوهش حاضر با هدف بررسی اثر ویژگیهای ادراکشده کودهای زیستی، بر مصرف این کودها در روستای ینگیجه از بخش مرکزی شهرستان زنجان انجام شد. جامعه آماری این پیمایش شامل تمامی کشاورزان فعال در این روستا (313=N) بود که 161 نفر از آنان به روش نمونهگیری در دسترس انتخاب شدند. معیار تعیین حجم نمونه، متناسب با حجم نمونه مورد نیاز برای استفاده از تکنیکهای چندمتغیری آماری بود که البته بر اساس فرمول کوکران نیز بسندگی حجم نمونه تأیید شد. بهمنظور جمعآوری دادهها از پرسشنامهای استفاده شد که روایی آن توسط صاحبنظران و پایایی آن از طریق محاسبه آلفای کرونباخ (برای بخشهای مختلف بالاتر از 7/0) مورد تأیید قرار گرفت. فن تحلیل تشخیصی به روش گام به گام برای بررسی اثر ویژگیهای نوآوری شامل «سازگاری ادراکشده»، «رؤیتپذیری ادراکشده»، «پیچیدگی ادراکشده»، «آزمونپذیری ادراکشده» و «مزیت نسبی ادراکشده» بر مصرف کودهای زیستی استفاده شد. نتایج حاصل از تحلیل تشخیصی نشان داد که «مزیت نسبی ادراکشده» بهعنوان تنها ویژگی کودهای زیستی است که توانست کشاورزان گروه «مصرفکننده» را از کشاورزانی که این کودها را مصرف نمیکنند، متمایز نماید. سایر متغیرهای وارد شده به تابع تشخیصی فاقد توان تشخیصی قابل قبول برای تفکیک سطوح متغیر «مصرف کود» بودند. ممکن است کشاورزان مختلف بهدلیل تفاوتهایی که از نظر شرایط مالی، فنی و مهارتیشان داشتهاند؛ ادراک متفاوتی از ویژگیهای کودهای زیستی پیدا کرده باشند. بنابراین پیشنهاد میشود در مطالعات آتی اثر ویژگیهای فردی- اجتماعی کشاورزان توأم با ویژگیهای ادراکی آنان از نوآوری مد نظر قرار گیرد.

شناسایی عوامل تعیین کننده آبیاری با استفاده از آب چاه و پساب تصفیه نشده فاضلاب در بین سبزیکاران شهرستان سنندج
علیرغم آن که آبیاری محصولات کشاورزی با استفاده از پساب خام فاضلاب دارای پیامدهای بهداشتی و زیستمحیطی نامطلوبی برای جامعه است، هر روزه شاهد گسترش این پدیده در کشور هستیم. این در حالی است که دانش چندانی در مورد عوامل اثرگذار بر استفاده از این منبع آلوده آب توسط کشاورزان وجود ندارد. در این راستا، مطالعه حاضر با هدف شناسایی عوامل متمایزکننده کاربران آب چاه از کابران پساب تصفیهنشده فاضلاب انجام شد. برای این منظور، 160 کشاورز سبزیکار در شهرستان سنندج از طریق نمونهگیری طبقهبندی تصادفی انتخاب و با استفاده از پرسشنامه مورد مصاحبه قرار گفتند. یافتهها نشان داد کشاورزان از دانش بالایی نسبت به کیفیت پساب خام برخوردارند. همچنین آنها نگرش نامطلوبی نسبت به پیامدهای بهداشتی و اجتماعی استفاده از پساب خام داشته و نسبت به اخلاقی نبودن استفاده از آن در آبیاری محصولات توافق داشتند. نتایج تحلیل تشخیصی نشان داد شش متغیر دانش، نگرش نسبت به پیامدهای اجتماعی کاربرد پساب تصفیهنشده، درک از خشکسالی، نگرانی در مورد گرمای جهانی، نگرش نسبت به پیامدهای بهداشتی کاربرد پساب تصفیهنشده و نوآوری به ترتیب بیشترین قدرت را در تفکیک کاربران آب چاه و کاربران پساب تصفیهنشده فاضلاب دارند. یافتههای حاصل از این مطالعه میتواند در سیاستگذاری برای کاهش استفاده از پساب خام مؤثر واقع شوند.
