Abstract
To address the dual challenges of urban expansion and ecological conservation, this study explores the efficiency of density transfer mechanisms within the Regional District of Nanaimo and Denman Island. Through a detailed analysis using the Normalized Difference Built-Up Index (NDBI) from Sentinel-2 imagery and Sensitive Ecosystem Inventory data, the study identified potential donor and receiver sites, facilitating a strategic reallocation of development intensity. The findings reveal that density transfer can significantly help with balancing urban development with ecological conservation, thereby supporting the three pillars of sustainability. The research highlights the critical role of accurate ecosystem valuation and the need for streamlined planning processes to enhance the efficiency of density transfers. By effectively identifying high ecological value areas and optimizing urban density, the study offers a visual and quantitative guidance for municipalities to navigate the complexities of sustainable urban planning. Urban densification emerged as a significant consequence, with implications for economic efficiency, reduced per capita energy consumption, and the promotion of vibrant community interactions, however it may also bring potential challenges in green space preservation and social well-being. This study underscores the necessity of integrating density transfer and densification strategies in urban planning to facilitate sustainable expansion while mitigating environmental impact and fostering community resilience. By demonstrating quantitative benefits and addressing the complexities of urban ecosystems, it advocates for informed decision-making in municipal development policies.
