REPRODUCING OPERATIONAL LANDSCAPES: The Rock Mining for Indonesia's New Capital City
Abstract Indonesia's new capital city is designed to become a green and sustainable city. In this article, we examine the (un)sustainability of the process through which the city is coming into being. Using the sociospatial theory of planetary urbanization, we trace the dialectical relationship between the new city and sites beyond it to show how ...
