“…Settlement system. Despite noting a wide variety of settlement types and developmental dynamism in SPTs [27], most existing literature on the topic has shown that the settlement systems of SPTs are closely related to the environmental capacity and physical characteristics of the territory: the sparse displacement is described as being "tapered" (situated along rivers, coasts, railway lines, and roads) [38,51,52] and "focal" (concentrated in areas containing natural resources, agricultural opportunities, or traditional indigenous communities and diffuse ex-urbanization landscapes) [29,52,53]. Many small settlements of urban primacy, between which there are few strong ties, have also been noted [38]; thus, small towns and urban settlements should either expand their functionality, or, in the absence of such opportunity, exist temporarily.…”
