城市農耕的公共拼裝：人、物種與物質的跨界氛圍與互動

Public Assemblage of Urban Farming: The Cross-Border Atmosphere and Interaction of People, Species and Materials

「友善環境」和「生態層序」為綠園道食物森林設計的其中兩項原則。綠園道食物森林立足於公共空間，永續材質的選用以及眾多非人物種的活躍，促使的公共性，捲入由人、物種與物質共構的多重張力。對此，筆者主張，綠園道的公共性不僅止於人類的行動，尚應包含物質與物種的匯聚，進而成就「自然」在空間中發揮的影響力。本文嘗試援引拼裝都市論及都市氛圍，萃取一套適宜的論述脈絡，探討非人是如何影響綠園道環境的公共性建構與內涵。本文採質性研究之參與觀察及半結構訪談進行資料蒐集與田野調查。本文發現，因綠園道空間的特性，以食物森林之「友善環境」和「生態層序」進行維護與管理，在實踐農耕的過程中，由物質與物種既存的特性而生的影響，是奠基後續公共互動的基礎。綠園道在基礎設施方面使用永續但卻易腐、易損的材質，雖有其弊端但也因此促成參與者間的對話；而非人物種的多變與不穩定性，同樣引發公共空間議題在都市社會中的協商。在拼裝都市論觀點下，異質元素具有能動性，且其組合形成一種動態卻穩定的過程。公共氛圍的營造，雖然仍以人為核心，但也離不開眾多異質元素的共生與共融。

“Friendly Environment”and“Ecological Sequence”are two of the principles of the Green Blet Food Forest design. The Green Parkway Food Forest is based on public space, and the choice of sustainable materials and the active presence of many non-human species contribute to the public nature, which involves the multiple tensions of people, species and materials. In this regard, the author argues that the public nature of the Green Parkway should not only include human actions, but also the convergence of materials and species, and thus the influence of“nature”in the space. This paper attempts to extract an appropriate discourse by invoking the theory of the assembled city and the urban atmosphere to explore how non-humans influence the construction and connotation of publicness in the greenway environment. This paper adopts qualitative research with participant observation and semi-structured interviews for data collection and fieldwork. The paper finds that the characteristics of the Greenway space, the maintenance and management of the“friendly environment”and“ecological sequence”of the food forest, and the influence of the existing characteristics of materials and species in the process of farming are the foundation for the subsequent public interaction. The use of sustainable but perishable and fragile materials in the infrastructure of the Greenway has its drawbacks but also fosters dialogue among the participants. In the view of assembled urbanism, heterogeneous elements are dynamic and their combination forms a dynamic but stable process. Although people are still the core of the public atmosphere, the symbiosis and integration of many heterogeneous elements are inseparable.
