Population, Environment, and Rural Livelihoods

Within all environmental contexts, sociodemographic, economic, and biophysical factors interact to yield important environmental changes. As an example of the interactions between these factors, regional economic shifts can bring population redistribution, which, in turn, impacts biodiversity through attendant land-use transitions.

A key part of Lori's current research agenda explores natural resources and rural livelihoods in sub-Saharan Africa.  The Agincourt Health and Demographic Surveillance Site in rural South Africa has served as the primary study setting for this work.  Topical foci thus far have included natural resources as coping strategies for HIV/AIDS-impacted households; the role of wild foods in food security; and migration as related to climate variability.

Some of Lori's earlier work in this area examined population-environment dynamics in Utah and the California Mojave.

Migration and Environmental Context

The American public has become increasingly aware of environmental issues especially during the past three decades. This increasing awareness has generally translated into more attention being focused on the effects of pollution and higher value being placed on surroundings free from environmental risk. Lori's research within this area has been motivated by the possibility that such environmental concern may be reflected in the choice of residential location.

Public Perception of Environmental Issues

Human-environment relations are also greatly affected by the ways in which individuals perceive their environmental context. Within this area, Lori's research has contributed to the body of literature examining social variation in environmental perception.
