Análisis espacial basado en SIG del malestar percibido ante industrias contaminantes: el caso del complejo industrial ventanas, Chile

The environmental effects of human activities shape the so-called externality fields around them, portrayed either as emissions and physical impacts, or as negative experiences affecting population. The measurement of this social bad-being and its spatial expression is the main issue of this contribution, where the case of residents near a large industrial complex in Chile is tackled. To this end a home survey, lately geo-referenced, was designed and achieved to determine the perception of various environmental impacts. To elucidate the amount of socio-spatial bad-being a kernel density estimator was applied, provided it enables to obtain GIS based surfaces and expressive maps representing the various negative experiences, and a synthetic index of them too. In this way it is intended to provide a way to capture, both in quantity and place, these elusive effects and to spread awareness about it.
