SAJJAD Lab

About the Lab

The SAJJAD Lab (Spatial Analytics for Just & Joint Adaptation to Disasters) is a research group at the Department of Geography and Resource Management, The Chinese University of Hong Kong, HKSAR, dedicated to advancing geospatial intelligence for systemic resilience.

"Just" here represents fairness, equity, and inclusivity in resilience-building through climate and procedural justice. It recognizes that the impacts of disasters and climate change are not felt equally. Vulnerable and marginalized communities or systems often bear the brunt of the damage but have the fewest resources to recover. Hence, when our lab pursues "Just Adaptation," it asks:

  • For whom are we building resilience?
  • Who is involved in the process?
  • Are the outcomes fair?
In essence, "Just" ensures that the benefits and burdens of adaptation are distributed equitably and that the process is inclusive.

"Joint" is about integration, collaboration, and systemic thinking. It refers to the breaking down of silos, with an emphasis that complex problems, such as disaster risk, cannot be solved by one discipline, one government department, or one sector alone. When our lab promotes "Joint Adaptation," it focuses on:

  • Interdisciplinary Research: Combining geography, data science, engineering, social science, and GeoAI.
  • Multi-Sectoral Collaboration: Bringing together governments, NGOs, private companies, and community groups.
  • Integrated Data and Systems: Coupling geospatial data with socio-economic data, infrastructure models with climate models, GeoAI and Machine Learning, etc.
In essence, "Joint" ensures that adaptation efforts are coordinated, holistic, and leverage diverse expertise and resources.

We cannot achieve "Just" adaptation without a "Joint" approach. Equity requires understanding social vulnerabilities (social science), mapping risks (geography), modeling hazards (climate science), and co-designing with communities (participatory action). It's inherently collaborative.

Lab Name Philosophy

SAJJAD from the Arabic word سجّاد means "one who is devoutly persistent" – reflecting our lab's ethos of rigorous, devoted inquiry into spatial problems for societal benefits and global good.

Our Mission

To develop integrative spatial analytics and forecasting frameworks that enhance community resilience to environmental hazards and climate change through evidence-based, actionable research.

Research Philosophy

We believe in translational geospatial science – bridging advanced analytics with practical applications for disaster risk reduction, sustainable urban development, and climate adaptation through employing spatial-information models, GeoAI, and Machine Learning.
