Abstract
Alotau, the capital town of Milne Bay Province, is experiencing rapid urbanization, leading to significant pressure on its limited land resources and demanding improved planning strategies. The urban expansion from 2005 to 2025 was analysed using Geographic Information Systems (GIS), remote sensing techniques and land use land cover (LULC) maps, and found a significant improvement in urbanization i.e., ~148%. The expansion was predominantly confined to low-elevation, low-gradient terrain, resulting in the conversion of vegetated and barren land covers, and was strongly regulated by topographic constraints. The LULC maps with high classification accuracy (> 85%), providing reliable, data-driven evidence of Alotau's growth patterns. These findings offer critical insights for town planners and policy makers, underscoring the urgent need for strategic and sustainable urban planning to guide Alotau's future development via. manufacturing firms, logistics planning etc., in a manner that is both resilient and environmentally conscious.
