GIScience, Environmental Justice and Estimating Populations at Risk: The Case of Landfills in Wales

<29> Studies in environmental justice have a high profile as the perceived spatial inequalities in the location of potential health-damaging and/or noxious facilities such as landfill sites have impacted on local populations. This study for the first time uses detailed population models derived from the use of dasymetric techniques, combined with GIS-based analysis, to compare and contrast the implications of using population denominators in such studies. This enables improvements in the estimates of the numbers of people potentially impacted by such schemes and enables a more discerned approximation of such trends in relation to socio-economic disadvantage for different population groups.
