As ecology becomes the new engineering, the projection of landscape as infrastructure--the contemporary alignment of the disciplines of landscape architecture, civil engineering, and urban planning-- has become pressing. Predominant challenges facing urban regions and territories today--including shifting climates, material flows, and population mobilities, are addressed and strategized here. Responding to the under-performance of master planning and over-exertion of technological systems at the end of twentieth century, this book argues for the strategic design of "infrastructural ecologies," describing a synthetic landscape of living, biophysical systems that operate as urban infrastructures to shape and direct the future of urban economies and cultures into the 21st century.
