The concept of landscape transcends various fields of knowledge and action. Despite the crucial paradigm shift due to the growing awareness of environmental issues, a disconnection persists between ecology and design disciplines. Ecology-based theories serve as invaluable allies, triggering multi-disciplinary communication and collaboration. The work Landscape through Ecology: from Theory to a Territorial Reading delves into Landscape Ecology theories by leading exponents through the description, cartographic exercises, and visual aids in the selected testing ground: Nyon. Operationalization hypotheses are proposed to be explored during all conception stages, aiming to achieve ecologically mindful and respectful projects across all scales. Nyon’s landscape is defined by water. Among rivers, streams and the lake we find the Cossy, a stream that traverses diverse contexts, agricultural and urban. This waterway has been heavily canalised and fragmented, being only 47% open-air. The project explores potential futures and scenarios of the renaturation and continuum of an urban stream. Possibilities are discussed to respond to a disconnection between water, humans and non-humans, a changing climate and the passage of time.
