Newell, and John C. Crittenden

Infrastructure Ecology is an emerging transdiscipline: Infrastructure Ecology alters and reorganizes energy and resource flows and considers the potential synergistic effects arising from infrastructure symbiosis. Understanding the city as an ecosystem requires knowledge of how human and natural infrastructure systems interact to create emergent properties. These infrastructures include physical infrastructure systems and their interactions (e.g., water-transportationenergy nexus), as well as ecological infrastructure, information and communications technology (ICT) infrastructure, socio-economic infrastructure (e.g., banking, finance) and social network infrastructure. It is Transdisciplinary. - It creates a body of knowledge distinct from its antecedents (engineering, ecology) that fundamentally changes the questions that are asked, and the tools used to answer them.
