The Importance of Including the Value of Soil in Metropolitan Planning Strategies

Metropolitan systems are developing rapidly, growing in number and size, frequently disregarding essential planning guidelines, primarily in terms of spatial distribution. According to UN predictions, urban and metropolitan systems will markedly expand in the next 3 decades, raising shared concerns in distribution management, determining inequalities between social classes, even in developed countries. Soil becomes, then, the most important economic asset, since correct spatial distribution rules will significantly influence the perception of value in urban and metropolitan systems, determining long term effects on decision-making processes.
