This paper critically examines Hong Kong's Multi-storey Livestock Farm Building Design Guide not as a voluntary innovation, but as a necessary adaptation for an industry in crisis. Against a backdrop of extreme land scarcity and aggressive urban development in the New Territories, which has decimated local agriculture to a mere 70-odd households, the guide represents a radical pivot towards hyper-intensive, closed-loop production as a last resort for survival. This study therefore investigates: Can the integration of livestock farming into multi-storey structures serve as a viable model for sustainable development in a hyper-dense city, and what are the key technical and socio-economic tensions inherent in this adaptation?
The research employs a qualitative case study methodology, conducting a critical document analysis of the guide. This analysis is framed within Hong Kong’s specific socio-political context of land scarcity and urban encroachment to evaluate the guide’s provisions against practical implementation challenges. The analysis reveals the guide to be a technically sophisticated blueprint for a metabolically closed-loop system, integrating waste-to-energy conversion, nutrient recovery, and precision farming. However, findings indicate the model is fundamentally a defensive adaptation to crisis rather than a proactive innovation. The central tension identified lies in balancing the engineering feat of vertical integration with critical concerns regarding animal welfare, operational economics, and the potential consolidation of a diminished agricultural sector. While the guide's interdisciplinary nature is a strength, it also exposes the complexity of reconciling building regulations, biosecurity, and agricultural viability within a single footprint.
This study provides a critical framework for policymakers, urban planners, and agricultural stakeholders in megacities globally. It moves the discussion beyond technical feasibility to highlight the profound policy and land-use decisions necessary to sustain urban food production, emphasizing that technological solutions must be coupled with supportive socio-economic policies to be transformative.
