 In today's urban landscape, the health and well-being of residents depends very much on the provision of urban blue and green spaces. SCI has been working with the city of Rudontani in northeastern Thailand, which has a population of around 135,000 people. It demonstrates well how a secondary city can maintain its green and blue public spaces for the health and well-being of its citizens who have space to relax, socialise and exercise. Rudontani is also an example of how various participatory tools can be used to engage local communities in design processes to ensure more just and inclusive cities. At SCI we have developed a toolbox for liveable cities, which showcases some of these tools.
