Urban densification erases coastal memory: Hong Kong fire survivor’s last view of Tolo Harbour as systemic displacement accelerates

The Tanka people, Hong Kong’s indigenous coastal dwellers, have fished Tolo Harbour for millennia, their identity intertwined with the sea’s rhythms and seasonal cycles. Their displacement by urbanization mirrors global patterns where indigenous coastal communities—from the Māori in Aotearoa to the Sama-Bajau in the Philippines—are forced into landless precarity by state and corporate land grabs. The erasure of sea views is also the erasure of cultural memory, where the horizon once held stories of migration, trade, and survival passed down through generations.

Hong Kong’s housing crisis traces back to British colonial land policies, which commodified space and prioritized speculative development over community needs. The 1990s handover accelerated neoliberal reforms, enabling developers to profit from high-density housing while neglecting safety standards in aging estates like Wang Fuk Court. Similar patterns appear in post-colonial cities like Mumbai and São Paulo, where colonial zoning and post-independence market liberalization created parallel crises of displacement and structural vulnerability.

In Mumbai, the 2018 fire at Kamala Mills Compound—another high-rise tragedy—revealed how urban densification displaces working-class communities from waterfront areas, mirroring Hong Kong’s loss of coastal memory. Tokyo’s 1980s land speculation bubble similarly erased traditional neighborhoods for concrete high-rises, leaving a legacy of social fragmentation. Across East Asia, the tension between rapid urbanization and cultural heritage is evident in Taipei’s Dadaocheng district, where historic waterfront communities resist displacement by invoking indigenous and Hakka land rights.

Urban heat island effects and poor ventilation in high-rise buildings exacerbate fire risks, as seen in Hong Kong’s 2012 Fa Yuen Street blaze and London’s Grenfell Tower disaster. Studies show that high-density housing without adequate green spaces and coastal buffers increases vulnerability to both fires and climate-related disasters. The loss of sea views also correlates with reduced mental well-being, as coastal proximity is linked to lower stress levels and higher life satisfaction in urban populations.

For many Hong Kongers, the sea is a spiritual anchor—a symbol of resilience and freedom, as captured in Cantonese opera and literature. The loss of sea views mirrors the erasure of poetic and philosophical traditions that once celebrated the liminal space between land and water. In Japanese ukiyo-e art, coastal scenes evoke impermanence (mujō), a theme resonant with Hong Kong’s disappearing vistas. The act of photographing the last sea view becomes a ritual of mourning, akin to Indigenous Australian practices of documenting sacred landscapes before their destruction.

By 2050, Hong Kong’s coastal flooding risks will increase by 30% due to sea-level rise, compounding fire hazards in aging high-rises. Scenario planning must integrate indigenous knowledge, such as the Tanka’s seasonal migration patterns, into urban resilience strategies. Cities like Rotterdam and Copenhagen offer models for climate-adaptive housing that prioritize community cohesion and green infrastructure over speculative development.

Elderly survivors like Ian Chu represent a generation caught between colonial-era neglect and post-handover gentrification, their stories sidelined in favor of market-driven narratives. Low-income tenants, many of whom are migrants from Southeast Asia, face double displacement—first from their home countries, then from Hong Kong’s housing market. Grassroots groups like the Society for Community Organization (SoCO) have documented how redevelopment projects systematically exclude tenant voices, treating them as obstacles to profit rather than stakeholders in urban planning.
