Adu, Stella Agyeiwaah and Gyang, Phyllis Ang-E-Mwin and Yakin, Zakaria (2025) The role of GIS and spatial analysis in enhancing urban resilience and disaster response for vulnerable U.S. Communities. World Journal of Advanced Research and Reviews, 27 (1). pp. 746-754. ISSN 2581-9615

Urban communities in the United States are increasingly threatened by the intersecting impacts of climate change, socio-economic disparities, and aging infrastructure, resulting in heightened risks from both natural and human-induced disasters, particularly for historically marginalized and underserved populations. This review critically examines the evolving role of Geographic Information Systems (GIS) and spatial analysis in enhancing urban resilience and improving disaster response. Drawing on current literature, case studies, and emerging applications, the paper explores how spatial technologies are utilized in key areas such as hazard mapping, risk assessment, social vulnerability analysis, evacuation planning, early warning systems, and post-disaster recovery. GIS facilitates the integration of spatial data, demographic information, and real-time analytics to help decision-makers identify high-risk areas, optimize resource allocation, and support timely and effective emergency responses. Case studies from cities like New Orleans, Miami, and wildfire-prone regions of California demonstrate how GIS-enabled interventions improve situational awareness and promote equitable, data-driven resilience strategies. However, significant challenges remain, including unequal access to GIS infrastructure, limited community participation, technological disparities, and ethical concerns surrounding data use. The review identifies promising opportunities through emerging technologies such as artificial intelligence, machine learning, the Internet of Things (IoT), and participatory GIS to build more inclusive, adaptive, and equitable disaster management systems. The study concludes with policy recommendations calling for greater investment in GIS infrastructure, capacity-building at the local level, interdisciplinary collaboration, and the integration of community perspectives to ensure that spatial tools effectively protect and empower vulnerable U.S. communities in the face of escalating disaster risks.
