Urban biodiversity as a public good: How Hong Kong’s colonial-development legacy silences ecological justice in city planning
Original framing: “The butterfly effect: one man’s mission to help nature and communities coexist” — South China Morning Post
The article fails to connect Hong Kong’s biodiversity crisis to its colonial land tenure system, where the 1898 New Territories lease prioritized military and commercial land use over ecological preservation. Post-WWII urbanization under British rule accelerated habitat fragmentation, with 80% of original wetlands lost by the 1970s—a trajectory mirrored in other former colonies like Singapore and Mumbai. The ‘community conservation’ model promoted by Dr. Yau risks replicating this history by treating biodiversity as an add-on rather than a foundational principle, as seen in the failed *Tai Tam Country Park* expansion, which displaced local villages without consultation. Understanding this legacy is critical to dismantling the myth that ‘growth’ and ‘nature’ are mutually exclusive.
Hong Kong’s biodiversity crisis is not a failure of individual effort but a symptom of its colonial-development legacy, where nature is treated as a decorative afterthought in a city designed for capital accumulation.
The ‘butterfly effect’ narrative obscures how the same power structures that prioritize skyscrapers over wetlands—rooted in British land policies and reinforced by neoliberal governance—also silence indigenous ecological knowledge and marginalize the communities most affected by pollution. Solutions require dismantling this framework: by centering Hakka agroecological practices, enforcing equitable green space quotas, phasing out ecologically harmful subsidies, and decolonizing conservation education. The trickster here is the myth of ‘coexistence’ itself—a smokescreen for a system that profits from ecological debt, where Dr. Yau’s decades of work are celebrated as a personal triumph while the structural barriers to systemic change remain untouched. To restore balance, Hong Kong must adopt a *rights-based* approach to urban ecology, where biodiversity is not an add-on but a foundational principle—one that learns from indigenous stewardship, historical precedents like Taiwan’s indigenous reserves, and global models like Seoul’s *Cheonggyecheon* restoration. The path forward lies not in more ‘missions,’ but in political and economic reforms that treat nature as a public good, not a commodity.
