Urban Green Infrastructure: Circular Socioeconomy with Nature Based Solutions

In a broader sense, we can consider the circular socioeconomy, which considers “material and immaterial” products and the corresponding services. In this context, to traditional material products, we could incorporate human health and well-being, which can also be recovered or recycled. As a general introduction, we describe urban strategies with environment and pollution dimensions, recycling, and insulated actions. Business and Nature Based Solutions (NBS) have to be coordinated with urban health. Research on social perception of green urban infrastructure was developed with a national online survey of the main actors: academics, entrepreneurs, functionaries, and others. The more significant opinions are analyzed. Case studies on energy and urban agriculture in Spain are complemented by some projects in Madrid. Special attention is given to the project gas recycling harm waste into urban benefits. The main objective are to identify and promote activities for social welfare throughout nature based solution, where circular economy throughout gas recycling is a useful instrument. Finally, the results include health impact, evaluation, and errors in socioeconomic circular actions.
