Community Expansion and Infrastructure Development: Implications for Human Health and Environmental Quality in the Galápagos Islands of Ecuador

Urban expansion and infrastructure development in Puerto Villamil, Isabela Island, Galápagos, pose significant risks to human health and environmental quality. The study reveals that the rapid growth of the community has outpaced the development of essential services like water and sanitation, leading to potential contamination and waterborne diseases. Researchers used a combination of geospatial analysis—including time-series aerial photographs and satellite images—to map infrastructure and assess its proximity to natural environments. Complementing this with qualitative data from interviews with health officials and residents, the study highlights the critical need for sustainable urban planning to mitigate adverse impacts on both public health and ecosystem integrity.
