  altering the transmission of infectious diseases in tropical regions. Hum
 an activities such as road construction\, urbanization\, and agricultural 
 expansion reshape ecosystems and human mobility patterns\, creating new op
 portunities for disease emergence and increasing health risks in vulnerabl
 e populations. Using tools from epidemiology\, ecology\, remote sensing\, 
 and causal inference\, I quantify how environmental change influences infe
 ctious disease dynamics across multiple systems. First\, I use species dis
 tribution models to map the habitat suitability of Biomphalaria snails\, t
 he intermediate hosts of schistosomiasis\, across Brazil. This work identi
 fies how urbanization and climate shape transmission risk and provides met
 hodological guidance for applying machine learning to disease ecology. Sec
 ond\, I examine how paving the Interoceanic Highway through the Peruvian A
 mazon in 2009 impacted the transmission of dengue virus. Using a quasi-exp
 erimental difference-in-differences design\, I estimate that the highway p
 aving led to a 403% increase in dengue incidence in nearby communities. Th
 ird\, I extend this analysis across the Brazilian Amazon\, where I develop
  a novel dataset linking 25 years of highway construction records to healt
 h facility-level dengue surveillance data. This analysis reveals that high
 way expansion drives increases in dengue transmission across the Amazon Ba
 sin and identifies the underlying conditions that amplify these effects. T
 ogether\, these studies demonstrate that infrastructure and land-use decis
 ions can have profound and measurable impacts on infectious disease risk\,
  underscoring the need to incorporate human health outcomes into impact as
 sessments and sustainable development planning.
