Thank You for Making
Geo4Impact 2025 a Success!
On May 27–28, 2025, the MAPME Initiative hosted Geo4Impact 2025 at AFD Headquarters in Paris and online, convening researchers, practitioners, and development professionals to exchange knowledge and promote reusable open geospatial solutions that address sector-specific challenges, strengthen project design, and improve evaluation and monitoring for greater impact. The event brought together 90 participants in person from 45 organizations, along with more than 100 remote attendees.
Bringing together experts in GIS, Earth Observation, and development cooperation, this year’s event fostered connections among thought leaders, practitioners, researchers, and a broader community committed to advancing open geospatial technologies within their organisations and areas of work.
Participants discovered cutting-edge open-source tools, explored practical examples of real-world applications, and shared experiences on how open geospatial data can drive more sustainable and evidence-based development outcomes. This dynamic exchange of ideas and lessons learned continues to build a global community working collaboratively toward more impactful and resilient development solutions.
Engaging Sessions and Presentations
Over two days, participants explored a diverse range of topics through presentations and interactive discussions that showcased practical applications of open geospatial solutions. Highlights included the use of satellite imagery to monitor environmental changes and support conservation efforts, strategies for integrating geospatial data into project design and policy-making, and examples of how open tools strengthen climate resilience and disaster preparedness. Speakers also shared insights on leveraging geospatial technologies for urban planning and sustainable city management, as well as innovative approaches to enhancing agriculture and food security. Together, these sessions provided actionable lessons and inspired participants to apply open geospatial approaches for greater development impact.
