DATA 4 EARLY WARNING HACKATHON 2025

Under the High Patronage of His Excellency Dr. Olavo Correia, the Deputy Prime Minister of Cabo Verde, we are pleased to announce that SatNav Africa Joint Programme Office (JPO), in partnership with the Government of Cabo Verde, Ministry of Digital Economy will be organising a high-level pre-event conference on Early Warning Systems with the Theme "Leveraging GNSS Technology for Enhanced Multi-Hazard Early Warning Systems (EMHWS) in Africa."

Africa confronts a rising tide of natural hazards, including floods, droughts, and earthquakes, which claimed 10600 lives and inflicted 15 billion dollars in economic losses in 2023, according to UNDRR reports. Floods alone affected 4 million people, particularly in coastal regions, while droughts devastated agricultural communities in arid zones. Climate change exacerbates these threats, disproportionately impacting Small Island Developing States and Emerging Markets with limited adaptive capacity. Launched in 2022, the UN Early Warning for All initiative aims to strengthen Multi-Hazard Early Warning Systems by 2027, emphasising detection, analysis, and timely dissemination of alerts. Global Navigation Satellite Systems, such as Galileo and GPS, provide high-precision geospatial and timing data, enabling real-time flood mapping, drought monitoring, and earthquake detection with millisecond accuracy.

The Africa Satellite Navigation Conference High-Level Pre-event which will focus on the role of GNSS technologies in advancing disaster resilience across the continent, will be held in hybrid format (Virtual and In person) from 16th to 17th of July, 2025, with the in-person component taking place at Parque Tecnológico Arquipélago Digital de Cabo Verde (Tech Park), Praia, Cabo Verde. It will serve as a pre-event to the planned Africa Satellite Navigation Conference, the first of its kind, scheduled for 2026 in Dakar, Senegal. The Africa Satellite Navigation Conference will offer a platform for African stakeholders to explore how Satellite Navigation and Positioning at large can bridge the gaps between urban and rural areas, in key areas such as early warning systems and disaster risk reduction, among others.

The Data 4 Early Warning Hackathon 2025, organised by SatNav Africa JPO and Africa Satellite Navigation Innovation Hub, runs virtually from 20th of May to 12th of July 2025, with results to be announced on the 15th of July 2025 in Praia, Cabo Verde, in a hybrid format. It engages 50 participants in 8 to 10 teams of 5 to 6 members to develop GNSS-based solutions through GeoStory Analytics and Policy Memo tracks. Across four phases, teams register, propose, develop, and submit deliverables, evaluated for innovation and MHEWAS integration, with winners gaining visibility at the Africa Satellite Navigation Conference High Level Pre event 2025. Key stakeholders including the European Union, African Union, SatNav Africa JPO, and the Ministry of Digital Economy of Cabo Verde support the initiative, offering opportunities for winners to build partnerships and scale their solutions across Africa.

CATEGORIES

  1. TRACK 1: GeoStory Analytics

Create browser-based tools using GNSS data (e.g., Galileo, GPS) to enhance disaster alerts. Build dashboards, storymaps, or infographics for risks like floods or droughts. Proposals are mentor-reviewed and developed into scalable solutions by July 12, 2025, supporting real-time early warning systems.

   2. TRACK 2: Policy Memo

Draft concise, data-driven memos advocating GNSS-based disaster policies. Use GNSS datasets to propose solutions like regional alert systems or monitoring networks. With expert feedback, refine proposals for submission by July 12, 2025, contributing to strategic frameworks for disaster resilience.

​Satellite4EarlyWarning Hackathon

Hackathon Theme: Advancing Satellite Navigation for Early Warning Systems

In this hackathon, participants will delve into the groundbreaking intersection of space-based technologies and early warning systems, with a particular focus on satellite navigation solutions. By harnessing the advanced capabilities of Global Navigation Satellite Systems (GNSS) such as Galileo, EGNOS, and Copernicus, teams will devise innovative approaches to enhance disaster preparedness and early warning mechanisms.

Key Focus Areas:

- Space-Based Innovation for Early Warning: Participants will explore how integrating satellite technology, including navigation and imagery, can revolutionize early warning systems. This integration aims to bolster disaster preparedness and response efforts, allowing for timely and effective interventions during emergencies.

- Satellite Navigation-Based Early Warning Systems: Teams will utilize satellite navigation technologies to develop precise and actionable disaster alerts. The goal is to create solutions that not only save lives but also reduce damage by providing tailored warnings specific to various types of hazards.

- Advancements in GNSS Across Domains: The hackathon will highlight the critical role of GNSS in diverse sectors such as aviation, maritime, agriculture, and transportation. Participants will showcase how advancements in satellite navigation can contribute to building resilient systems and improving overall safety and efficiency in these domains.
 

Illustrative Examples:

- Participants will have access to case studies that demonstrate the real-world applications of geospatial technologies in disaster management. These case studies will feature scenarios where data from Galileo, EGNOS, and Copernicus have been used to issue early warnings, manage evacuation procedures, and support recovery efforts following disasters.​

- Teams will analyze and leverage datasets from geospatial technologies to create predictive models, visualization tools, and decision support systems aimed at enhancing early warning capabilities. By tapping into the extensive satellite data available, participants will develop solutions with tangible benefits for regions prone to natural disasters.
