شاخص ریسک امنیت آب

0–10 index of water security risk combining scarcity and stress, WASH access, water quality and transboundary dependence; geometric so that good access does not offset severe scarcity.

وضعیت

روش‌شناسی، ساختار و تعاریف The Global Risks Index پیش‌نویس کاری مقدماتی (2026) است که برای بررسی و اظهارنظر منتشر شده و برای اجرا نیست. هیچ مقداری نمایش داده نمی‌شود تا ویراستی از یک برش شواهد تحت حکمرانی منتشر شود؛ آنگاه مقادیر همراه با بازه‌ها، رده‌ها، منابع و مسیر اصلاح خود ارائه می‌شوند. شبیه‌سازها روش‌های منتشرشده را بر روی اعدادی که شما برمی‌گزینید اجرا می‌کنند و هرگز مقداری از NXS-GRX نشان نمی‌دهند.

آنچه ⁨NXS-GRX⁩ نیست

⁨NXS-GRX⁩ اطلاعات پژوهشی و تحلیلی ریسک است. رتبه‌بندی اعتباری یا ⁨ESG⁩ نیست و از هیچ مقیاس رتبه‌بندی استفاده نمی‌کند، شاخص مرجع ابزارهای مالی نیست، آمار رسمی نیست، هشدار اضطراری یا طبقه‌بندی رسمی نیست و توصیه نیست. نباید برای ارزیابی اشخاص حقیقی به کار رود. طبقه‌های ریسک بازه‌هایی روی یک مقیاس منتشرشده‌اند، هرگز رتبه‌بندی کشورها یا افراد نیستند.

نهادها و منابع

The Nexus Consortium is stewarded by three independent not-for-profit institutions: The Global Centre for Risk and Innovation (GCRI), through GCRI US in Washington, DC and GCRI Canada in Ontario, with GCRI Canada as Lead Institution, Consortium Secretariat and lead contracting organisation; The Global Risks Forum (GRF); and The Global Risks Alliance (GRA). Technology, infrastructure and service providers work with the Consortium at arm’s length under written agreements, like every other external party in the public-private-planet model, and hold no role in its stewardship.

Avis en français

La méthodologie et les définitions du NXS-GRX sont un projet de travail préparatoire (2026). Le NXS-GRX est une information de recherche et d’analyse des risques : ni notation, ni indice de référence financier, ni statistique officielle, ni alerte, ni conseil. Les classes de risque sont des bandes sur une échelle publiée, non des classements.
