Approach: It also uses information about demographic changes, hydrologic data and land cover change in the Arequipa region for the last 17 years. The goal is to understand the relationship between urbanization, water quality in the Chili River and incidence of gastrointestinal diseases. Results: Landsat imagery was used to determine this relationship and to extrapolate business as usual trends into the future ten years from now. Results indicate that there has been notable urban growth and a loss in volcanic material land and cropland between 1990 and 2007, as new urban developments have appeared in these areas. The population expansion over volcanically active area is particularly troubling since it poses a potential human health risk. We also model a business as usual scenario out to the year 2020, which shows continued loss of these land use types and serves as a warning for land managers to consider alternate policies. Conclusion/Recommendations: The analysis also shows a direct correlation between urbanization with the decrease of water quality and the increase in the incidence of gastrointestinal diseases. 2011-05 published Science Publications 10.3844/ajessp.2011.90.101 XJ-11-099 American Journal of Environmental Sciences; 7(2):90-101 (26 May 2011) [doi:10.3844/ajessp.2011.90.101] 84 public American Journal of Environmental Sciences 7 2 90-101 TRUE 1558-3910 FALSE info:eu-repo/semantics/article
