Title: Modeling the per capita ecological footprint for Dallas County, Texas: Examining demographic, environmental value, land-use, and spatial influences
Author: Ryu, Hyung Cheal
Abstract: This study addresses factors driving the variation in the per capita Ecological Footprint (EF ) in Dallas County , Texas . A main hypothesis was that scientifically estimated demography , environmental values , spatial attributes , and land -use patterns surrounding an individual are significant factors in the size of per capita EF . This study was based on the survey method and GIS routines . Additionally , a multiple regression method was employed to address the study question . The survey measured respondents ? ? EF using an ? ?Ecological Footprint Quiz ? ? consisting of sixteen questions regarding individual food , mobility , housing , and goods /services consumption . GIS technologies were used to objectively measure spatial attributes . The environmental values were measured by selected questions regarding ecological crises . This study found from the descriptive analysis that Dallas County ? ?s average personal EF was 26 .4 acres : food (5 .1 ) , mobility (3 .3 ) , shelter (8 .3 ) , and goods and services (9 .8 ) . The study indicates that the residents need ecologically productive land more than 105 times the area of the county . Based on the explanatory analysis , the following summary points can be made about the factors driving of the variance , not only in the per capita composite footprint but also in each of the personal footprint components : First , a highly educated , non -married , older male living in a high income household located in a low population density area is more likely to have a larger personal composite footprint . Second , a person with a weak environmental awareness living where the ratio of employment opportunities (places to work ) is worse , and living far from freeways and major lakes but close to major malls , is more likely to have a larger personal food footprint . Third , a younger person living in a high income household located close to major malls but far from Dallas /Fort Worth Airport is more likely to have a larger mobility footprint . Fourth , a highly educated non -married older male living in a highly developed area is more likely to have a larger shelter footprint . Fifth , a highly educated non -married older male living in a high income household located in a low population density area is more likely to have a larger goods and services footprint .
