ANNOTATSIYA.
Ushbu maqolada global iqlim o‘zgarishi sharoitida oziq-ovqat xavfsizligini
ta’minlash muammosi kompleks tizim sifatida tahlil qilingan. Qishloq xo‘jaligi ishlab
chiqarishi, agroekotizimlar barqarorligi, suv va tabiiy resurslardan foydalanish
samaradorligi hamda global oziq-ovqat taqsimoti jarayonlari o‘zaro bog‘liq dinamik
tizim sifatida o‘rganildi. Ilmiy yondashuv sifatida simulyatsion model, qiyosiy tahlil
va tizimli baholash usullari asosida normal iqlim sharoiti va global isish ssenariysi (+1–
2°C) taqqoslandi. Olingan natijalar harorat oshishi hosildorlikning 6–9% ga kamayishi,
vegetatsiya davrining qisqarishi, suv resurslaridan foydalanish samaradorligining
pasayishi hamda oziq-ovqat mahsulotlari sifat ko‘rsatkichlarining yomonlashishini
ko‘rsatadi. Ushbu jarayonlar iqlim o‘zgarishining kaskadli va tizimli ta’sir
mexanizmiga ega ekanligini tasdiqlaydi. Global oziq-ovqat xavfsizligini ta’minlashda
faqat agronomik emas, balki iqtisodiy, ekologik va ijtimoiy omillarni
integratsiyalashgan holda yondashish zarurligini ko‘rsatadi.
