Rethinking Ground

2018, Unmaking Waste, UniSA Adelaide

This investigation begins from an empiric approach during an ongoing landscape project of a depot of inert waste to be placed in a valley in Switzerland, as well as from considerations on the elementary actions of moving ground inside a building site. The process of re-shaping the land with earth historically has had great consolidated implications for metropolitan, urban, rur-urban and agricultural life: sacred, social, ecological, artistic, political and economic. Currently, within the global economic and environmental context, the reuse of earth and recycling of inert waste represents necessary political, social and design issues, as well as a fundamental aim of the 7th Environment Action Program and the UN’s Sustainable Development Goals. How can we participate in this challenge, through Landscape Architecture? This study critically interlaces theoretical patterns, crossing the borders between the vision on waste and ecology of Gregory Bateson, Braungart and McDonough, proceeding through Ecological Urbanism and the holistic understanding of the site by the topological approach developed by ETH Zürich and Atelier Girot. Realized study cases are examined as evidence or results of those methodologies and as examples of creative design. In particular, this paper highlights how large amounts of inert waste have been used for a renaturalization practice of a river delta or, through a topological intervention, for the design of an artificial mountain in a delicate environment, concluding with a cultur-scaping which rehabilitates an existing landfill, leaving behind the evidence of its earlier existence and transforming it, thanks to the cultural approach of design, into a park.
