Although the industrial release of pollutant substances into North West European river delta has been decreasing over the last decades, The Netherlands still has one of the worst water qualities in Europe. In this strategic regional design we aim to improve the quality, quantity and distribution of water through the concept of sustainable land use. Industrial waste, waste water and increasing demand for land are the main pressures on our river water system. Considering the future risk of flood and drought there is also a big insecurity about our water quantity. There will be a need for more space and fair use of our water system. The goal is to restore the water quality in the North West European river delta and secure a sufficient water quantity for future use, flood protection and a fair distribution of the water available. In this report research by design is used to develop a spatial vision and spatial strategy that will create spatial water justice and with that a healthy river landscape. There are three themes related to spatial water justice: water quantity, quality and distribution. To meet sufficient standards for these three themes there are three important concepts: a circular industrial water system, decontamination and room for the rivers. All of them deal with the broader concept of sustainable land use. Sustainable land use is the fair and balanced distribution of land and environmental resources. This report shows a regenerative decontamination design for the North West European river delta. It is the development of a catalog of interventions that can be used in the whole river basin. Many small changes make a big difference in an interconnected system like a river basin. Every small intervention that will help clean the water, adds to the whole system and changes the whole system into a healthy and just river landscape. Together with this catalog there is a manual where the interventions are connected to spatial qualities of a specific location. The catalog and manual have been implemented for the case of South - Holland / Rivierenland. This example shows how we assure a sufficient water quality, quantity and fair distribution of water in a long-term perspective in the North West European Delta region.

Urban viaducts are essential components of main road networks in large cities. Balancing the enhancement of urban traffic efficiency with the preservation of urban space vitality is a significant challenge for many major cities in China. The Renmin Road Viaduct in Guangzhou exemplifies the conflict between unsustainable traffic development and daily life, serving as the primary focus of this study. This project aims to achieve the macro goals of community livability and sustainable transportation through the integrated transformation of the Renmin Road Viaduct. The objective is to convert the viaduct from a negative urban space into one that positively impacts the city, thereby improving the living conditions of surrounding residents and alleviating messy traffic situations. The project employs a combination of literature review, GIS traffic data processing and analysis, and surveys. By focusing on cultural, economic, social, and ecological dimensions, the design goals of "neighborhood livability" and "sustainable mobility" can be achieved through the transformation of integrated infrastructure. Transforming the Renmin Road Viaduct into a pedestrian-priority bridge offers innovative ideas and references for the renovation of similar urban viaducts in China.
