Urban Dependency is a must read for scholars in the area of environmental, urban and rural sociology, and the sociology of development. The book provides an excellent compendium of thought and future directions for theorizing and modeling population-environment interactions. Fulkerson and Thomas’ energetic analysis of the world system is unparalleled. They deftly wed areas of emphasis in novel ways, complemented with methodological tools appropriate for such large-scale, cross-cutting analyses. Their construction of a world-level system dynamic model is a major contribution to knowledge surrounding global sustainability. As the rural-urban divide incites greater inequality worldwide, an analytic approach such as this is of increasing importance.

Avoiding complex socio-ecological dynamics between rural and urban areas, many environmental scholars have framed city-life as a solution to the global environmental crisis. With novel theoretical and empirical insight, Fulkerson and Thomas address these dynamics head-on and present a challenge to the conceptual hegemony of cities in the environmental literature. Moving from localized cases to global analyses, their work shows how an uneven settlement system circulates with an uneven ecological exchange between rural and urban. Fulkerson and Thomas stress that the question of human settlement must not be taken for granted in discussions of sustainability, as it often is.

Fulkerson and Thomas provide a superb presentation of urban dependency and an illuminating discussion of how the current urban-rural system is an unsustainable one that privileges urban populations over rural people. Urban Dependency tackles the large theme of sustainability by focusing on the often overlooked urban-rural dimension. It’s a clearly written and timely account that combines a clear summary of societal energy demands with their introduction of a new energy accounting method, Caloric Well Analysis. We urgently need a societal discussion about the urban-rural relationship, and this book makes a thought-provoking contribution to that discussion.
