In 2018, Taiwan has become the “aged society” as National Union defined with 14% of total population are project to be the elderly. By 2050, there will even become twice amount of it, with more than one-third of the total population are consist of the elderly. The ageing of society is a positive yet challenging phenomenon. As Mace said in his public speech “We all become disabled as we age and lose ability, whether we want to admit it or not.” (Ron Mace, 1941-1998) The concept of the universal design pyrimid from Goldsmith also indicates that disabled and elderly people should been put at the priority as they are among those who experience the greatest difficulties in their daily life in the built environment, if the space is friendly to them then it should be usable for everyone. “Unfortunately, designers in our society also mistakenly assume that everyone fits this definition of “normal.” ”(Ron Mace, 1941-1998) Therefore, from the planner and designer aspects, it is important to create a supported built environment and well-design outdoor spaces which can promote physical activity and helps to preserve and maintain older people’s health and well-being.

The Netherlands exported in 2017 for 91,7 billion euros and exported for even more: 62,6 billion euros(CBS, 2018). This shows the big agri-food fl ows in which the Netherlands is involved. Sadly, these global fl ows have a big impact on economic, social and environmental sustainability worldwide. For example, transport causes many emissions, there is an unfair economic system that keeps farmers trappedand there is a lot of environmental damage. This is a situation that needs to change, but the Netherlands is also very dependent on the economy that the worldwide trade brings. This shows the problemthat South Holland is dealing with: The Netherlands is too much economic dependent on its agri-foodimport and export fl ows and is thereby causing economic, social and environmental sustainability challenges.This report proposes to DownScale international agri-food fl ows and Scale-Up a regional food system.The import and export fl ows are limited to only the European Union while food hubs and knowledgenetworks contribute to a system in which local food consumption and participation are important values. Waste, water and CO2 systems contribute to a circular approach of these DownScaled fl ows andthe production of seaweed helps to change the diet which is necessary to make a DownScaled systempossible. The report is supported by a sustainability triangle resulting from the nested sustainabilitymodel, the R-ladder of sustainability and the X-curve for a sustainable transition. A toolkit of interventions is designed as a strategy to achieve the vision goals. With DownScale-Up a new circular economywith DownScaled international fl ows and a Scaled-Up regional food system, is created by 2050.
