اختتمت وكالة الإمارات للفضاء البرنامج التدريبي الخاص بـ"الميثاق الدولي للفضاء والكوارث الكبرى" في جامعة زايد – أبوظبي، والذي جمع نخبة من الشركاء والخبراء من مختلف الجهات في الدولة، بهدف تعزيز التنسيق ورفع الجاهزية التشغيلية وتطوير توظيف بيانات الأقمار الصناعية في دعم الاستجابة للكوارث. ويأتي هذا البرنامج بالتزامن مع تولي الوكالة رئاسة الميثاق الدولي للفضاء والكوارث الكبرى لمدة ستة أشهر، وبالتعاون مع شركائها الوطنيين: الهيئة الوطنية لإدارة الطوارئ والأزمات والكوارث، ومركز محمد بن راشد للفضاء، وشركة «سبيس 42». The UAE Space Agency has concluded its training program on the International Charter: Space And Major Disasters at Zayed University in Abu Dhabi. The program convened leading partners and experts from across the UAE to strengthen coordination, enhance operational readiness, and advance the use of satellite data in disaster response efforts. This initiative comes as the Agency assumes the presidency of the International Charter for Space and Major Disasters for a six-month term, and is delivered in collaboration with its national partners: the National Emergency, Crisis and Disaster Management Authority, the Mohammed bin Rashid Space Centre, and Space42.

It has been a packed and impactful week of activities at RCMRD. We successfully concluded the Regional Symposium 2026 – “Space Technologies for Humanity” (16–17 February) and immediately transitioned into the Regional Training on Space Technologies for Disaster Management and the Use of COS-2 and the Charter Mapper during Activations (17–20 February). Organized by RCMRD, the back-to-back engagements were held with the support of the @UNOOSA) through the @UN_SPIDER programme, the University of Bonn – Centre for Remote Sensing of Land Surfaces @ZFL, and the International Charter on Space and Major Disasters. From high-level Disast3r risk reduction dialogue to hands-on operational training, participants strengthened their capacity to activate the Charter through the COS-2 web platform and mapping using the Charter Mapper, translating EO data into actionable information for disaster response. #DisasterManagement @czaran #chartermapper @DisastersChart

Over the past 3 days, participants in the Regional Training on Space Technologies for Disaster Management and the use of COS-2 and the Charter Mapper have been strengthening their skills in applying space technologies to real-world disaster response. 🛰️🌍 Through hands-on sessions, they have learned about the different roles in COS-2 -including Authorized Users, Project Managers, and End Users -and workflows on the Charter Mapper for mapping floods, droughts, earthquakes, landslides, and wildfires. The final outputs from these workflows can be transformed into actionable disaster response products, enabling faster, smarter, and more effective emergency management. @DisastersChart @czaran @aamdihun @IGAD_CPAC @allanoware @UNOOSA @UN_SPIDER @Vittorio Trivigno @RobertoBiasutti @MichaelSchmidt

When disaster strikes, response time is critical. The International Charter on Space and Major Disasters provides free satellite imagery to support countries affected by #floods, #earthquakes, #landslides, #cyclones, and other major disasters. Authorized users can activate the Charter 24/7 through a single access point - and within hours or days, receive analyzed satellite maps to guide emergency response and recovery efforts. This global collaboration of space agencies ensures that critical Earth observation data reaches those who need it most -helping save lives, protect infrastructure, and safeguard the environment.
