THE GEOMORPHOLOGICAL NICHE OF TREES

In a 2009 article I introduced the concept of a geomorphological niche, defined as the resources available to drive or support a particular geomorphic process (the concept has not caught on). The niche is defined in terms of a landscape evolution space (LES), given by

where H is height above a base level, rho is the density of the geological parent material, g is the gravity constant, and A is surface area. The k’s are factors representing the inputs of solar energy and precipitation, and Pgrepresents the geomorphically significant proportion of biological productivity (see this for the  background and justification).

Negotiating Life: Resilience in an Era of the China Dream

Ecological practices of daily life have taken on new urgency and approaches as consumer citizens increasingly voice awareness of environmental sustainability in China. This lecture will focus on "everyday ecologies"--personal engagement with social and material worlds to negotiate well-being. 

Professor Nancy Chen is Chair of the Anthropology Department and an affiliate of East Asian Studies and Feminist Studies at UC/Santa Cruz. Her research interests include Chinese biotechnology, food and medicine, and alternative healing practices. She is author or editor of six books, including China Urban

Sponsored by the Department of Anthropology and the UK Confucius Institute.
