This paper describes a proposal for the sustainable rehabilitation of a neglected and marginal fluvial landscape. It situates the experience into a broader debate about sustainability and spatial design, and then draws from it some general conclusion. The study subject is a fluvial valley characterised by thirty-six mills, which once served the agriculture of the surroundings. The decline of water as power source let to the decline of the valley. The mills became eventually farms, houses, or were left empty. The proposal envisions multiple forms of interaction with the different contextual issues related to the context, turning the design of the water course in a way to cope with erosion and floods, to produce clean energy, and finally as attractor for tourism. The result is a series of integrated actions that offers new opportunities to the community, designing a new sustainable landscape drawing from the specific natural and historical aspects of the site. Every action is linked with one of the anthropic and natural factors that characterise the valley, or that can be beneficially introduced, so that the proposal can be further adjusted in accordance with the relative importance of each factor over time.

被忽视和边缘景观的可持续恢复：撒丁岛的圣洛伦索山谷

本文描述了一项关于对被忽视的边缘河流景观进行可持续恢复的建议。它将经验置于关于可持续性和空间设计的更广泛的辩论中，然后从中得出一些一般性结论。研究对象是一个河流山谷，其特点是有 36 个磨坊，这些磨坊曾经为周围的农业服务。作为动力源的水的衰落导致了山谷的衰落。磨坊最终变成了农场、房屋，或者空置。该提案设想了多种形式的互动与与背景相关的不同背景问题，将水道的设计转变为应对侵蚀和洪水的方式，生产清洁能源，并最终成为旅游的吸引力。结果是一系列综合行动为社区提供了新的机会，从场地的特定自然和历史方面设计了一个新的可持续景观。每个行动都与表征山谷的人为和自然因素之一相关联，或者可以有利地引入，以便可以根据每个因素随时间的相对重要性进一步调整提案。
