Geographic Information Systems (GIS) are proving to be indispensable resources for Pacific islanders confronted with significant challenges that require intelligent, data-informed solutions. This critical insight was shared by Sakiasai Ditoka, the outgoing Minister for Rural & Maritime Development and Disaster Management, during his keynote address at the 2025 Pacific Islands GIS & Remote Sensing User Conference held in Suva in November.
Ditoka emphasized that the region is at the forefront of climate change, facing increasingly severe storms, rising sea levels, and changing rainfall patterns, all of which threaten food security and essential services. He remarked, “In this context, Geographic Information Systems are not just tools. They are lifelines.”
GIS-enable users to create digital maps that facilitate the storage, analysis, and layering of diverse location-based data collected through remote sensing techniques, which employ sensors and cameras on satellites or aircraft to gather information about the Earth’s surface. Ditoka highlighted the pressing need for utilizing GIS and remote sensing to gather and analyze baseline data essential for effective urban, rural, and coastal planning, which ultimately aims to safeguard cultural resources and cultivate resilient communities capable of tackling the impacts of climate change.
Bradley Eichelberger, Chair of the Pacific GIS and Remote Sensing Council, pointed out that the conference serves as more than just a meeting of experts; it is a vital investment in the skills and partnerships necessary for data-driven decisions that enhance the well-being and resilience of Pacific communities. He noted the remarkable evolution of the event, which has grown from humble monthly gatherings in 1991 to a fully recognized week-long international conference. Originally launched as a National GIS Conference in 1998, it now features an extensive program designed for networking and informal discussions alongside scheduled presentations.
With the conference themed ‘Building and Enhancing Geospatial Networks in the Pacific,’ it presented 45 impactful presentations to an audience of 170 attendees, comprising international researchers, professionals, academics, NGO representatives, private sector partners, and government officials from 23 countries. This collaboration underscores a commitment to leveraging geospatial data for the advancement of communities across the Pacific, fostering an environment of growth and resilience in the face of environmental challenges.
