Conservación de ecosistemas en obras de infraestructura a gran escala Ecosystem conservation in large-scale infrastructure projects

Urban infrastructure projects in megadiverse countries pose significant environmental challenges, especially when developed in ecologically strategic areas such as riparian zones, Andean forests, and páramo ecosystems. This article analyzes three large-scale infrastructure projects executed in Bogotá, Colombia: the El Salitre Wastewater Treatment Plant (PTAR), the landslide mitigation works along Avenida Circunvalar, and the overflow system of the Chuza Reservoir. Through a qualitative multiple case study approach, the research identifies key strategies for integrating ecosystem conservation into infrastructure design and execution. Results show that early environmental planning, technical environmental leadership, and community participation are critical to achieving ecological resilience. The study highlights replicable practices such as ecological zoning, native species revegetation, and participatory monitoring. These findings provide relevant insights for environmental governance, sustainable infrastructure policy, and urban biodiversity conservation in high-pressure regions.
