Chile's Tech Hub Dreams: Wetlands Dry Up

Chile is striving to become Latin America's leading technology hub, attracting significant investment in datacenters. However, this growth is placing immense pressure on the nation's water resources, particularly in drought-stricken areas like the Quilicura wetland near Santiago. Datacenters, essential for cooling server networks, consume billions of liters of water annually.

Activists and residents are raising alarms about the environmental impact, citing the drying up of wetlands, minimal job creation compared to the infrastructure's footprint, and significant energy consumption. Studies estimate that datacenters' water usage, especially for AI-related operations, is substantial and exacerbates scarcity in regions like central Chile.

While companies like Microsoft and Ascenty claim to use water-efficient cooling systems and engage in water restoration projects, concerns persist. The national plan to boost Chile's tech sector, initiated in 2023, is now facing scrutiny over its sustainability. Experts propose relocating new datacenters to the more water-abundant southern regions of Chile.

Further complicating the issue are high energy demands and the reliance on fossil-fuel backup generators. Residents in areas like Cerrillos successfully halted a proposed datacentre project due to inadequate consideration of climate impacts. The future regulatory environment for datacenters is uncertain, with potential policy shifts favoring investment over stricter environmental controls.
