Environmental management and alluvial flood risks in Antofag

Overview

Environmental and economic management in Antofagasta, Chile, has focused on regional sustainability and climate resilience. Regional authorities have prioritized air quality improvements in Calama, waste management via a circular economy approach, and the implementation of a Regional Climate Change Action Plan. In August 2026, Regional Ministerial Secretary of the Environment Verónica Araneda Gómez detailed progress on the Air Quality Monitoring Network in Calama and the declaration of the Río Loa Urban Wetland. Economic data indicates significant environmental investment, with 12 approved projects totaling approximately US$6.739 billion and 33 projects under evaluation representing a potential US$28.862 billion.

Efforts to address the climate emergency have extended to the artisanal fishing sector in Caleta Coloso. In August 2026, Biminister of Economy, Development and Tourism and Mining Daniel Mas met with local organizations, including the Coloso Union and the AGREUMAR Guild Association, alongside representatives from Escondida | BHP, to discuss recovery mechanisms and sustainability for coastal communities.

Recent heavy rainfall and alluvium have triggered an ecological and sanitary crisis, washing illegally dumped waste and animal carcasses into the sea. Compounding these risks, Antofagasta Mayor Sacha Razmilic has warned of irregular settlements and camps located within four critical ravines: El Toro, Farellones, Uribe, and Baquedano. During a field visit with the Ministry of Public Works (MOP) and the Directorate of Hydraulic Works (DOH), officials observed improvised dwellings utilizing MOP infrastructure for housing or sewage discharge. A multi-sectoral working group has been established to coordinate risk reduction and infrastructure maintenance.

To bolster disaster preparedness, the region has expanded its hydrological monitoring network. New fluviometric stations were installed in Yerbas Buenas and Río Salado, alongside meteorological stations in Sierra Gorda, Caracoles, and Bonilla TK. This data is integrated into the Dirección General de Aguas (DGA) to assist agencies like SENAPRED during extreme weather events.
