As a peripheral agricultural city in northeastern China, Suihua is experiencing severe population loss, having lost approximately one-third of its residents between 2010-2020. The city exhibits classic shrinking city characteristics - rapid urban decay, economic stagnation, poverty concentration, and social segregation - yet lacks effective intervention measures to address these challenges. This urgent situation demands immediate action to mitigate the spatial, economic and social impacts of depopulation. Centered on the concept of smart shrinkage, this project establishes a comprehensive framework targeting three core objectives: Social Cohesion, Urban-Rural Economic Growth, and Spatial Efficiency. Through systematic analysis, we identified four distinct typologies of shrinkage risk areas in Suihua, conducting field surveys and interviews to document spatial characteristics and user preferences for each type. These findings informed the development of four tailored intervention strategies: Urban Living Room, Super Community, Modern Creative Industry Park, and Industrial Composite Zone. The project's innovative "spatial-economic-social" tripartite response mechanism has yielded three groundbreaking contributions to China's unique "urban suburban-rural" triaxial shrinkage structure: (1) a spatial optimization model based on adaptive reuse principles; (2) an economic revitalization approach extending agricultural value chains; and (3) a culturally-grounded social stabilization strategy. These practical solutions establish a replicable governance paradigm for regions facing similar developmental challenges. ... Read more

Nitrogen is an essential element of planetary life. Yet, human actions create such a surplus of its derivatives like ammonia (NH3) and nitrogen oxides (NOx) that the naturally occurring amounts doubled, causing a cascade of environmental and societal problems.
Our research studies dairy farming in North-West Europe with a focus on the Netherlands, as this industry is responsible for most nitrogen-related problems. The starting point of the project is the parliamentary letter ‘Nationaal Programma Landelijk Gebied’ (National Rural Area Program), which offers the alternatives of quitting, transforming or relocating dairy farms in areas where the nitrogen surplus exceeds critical loads. We reevaluated this approach using the methods of extreme scenarios, in-depth stakeholder analysis, as well as layering and clustering areas with high nitrogen deposition, pasture lands and socio-geopolitical issues. This led us to the realisation that a substantial spatial and societal transition is needed in order to reach balance again. The goal of this study is therefore to recalibrate the nitrogen cycle by radically changing current dairy production practices. We created a gradient from quitting to transforming farms and pastures, based on the theories of transitional landscapes and socially just transitions, resulting in a toolbox of eight strategic interventions, as well as a thorough policy framework. We choose a multi-scalar approach to test the new typologies, starting from the Netherlands, looking at the Groningen - Friesland - Drenthe region, further zooming in on the municipality of Ooststellingwerf, showing the phasing of the strategy from a human perspective. Essential lessons learned are the importance of collaboration on all scales, as well as the flexibility and openness towards change, whether it is technological or societal. Finally, based on these findings we extended our zoom to the scale of North-West Europe, giving suggestions to regions with similar problems.
This project describes a possible future based on our interpretation of the parliamentary letter, giving an intriguing input to decision makers on what their policies could mean, hoping to change the discourse regarding nitrogen, shifting its perception from pollution to a valuable resource.
