At ALMA, working with neighboring communities is a key part of our presence in Chile. Beyond science and observing the universe, there is a real and ongoing commitment to local development, particularly in the Antofagasta Region, where our closest communities — San Pedro de Atacama and Toconao — are located.

For over a decade, we have been working on the ground to build trust-based relationships, recognizing that direct, respectful, and ongoing dialogue is essential to long-term, positive coexistence. As Catalina Margulis, ALMA’s Corporate Secretary, explains: “Local communities are our neighbors. To build trust, direct and continuous contact with them is essential.”

The team’s work is guided by three pillars: transparent dialogue, respect for the Atacameño culture, and collaboration on projects that align with shared interests. In practice, ALMA supports initiatives mainly focused on science education and cultural preservation. Among these are the Inquiry-Based Science Education program, which provides training and tools to local teachers and school leadership, and the Atacama Makers workshop, which encourages creative thinking and the use of technology to help students solve local challenges.

Cultural heritage is also supported through initiatives like “The Universe of Our Ancestors”, an ethnoastronomy book that shares the Atacameño worldview, as well as efforts to preserve historic pastoral sites and ancient structures linked to astronomical observation.

In addition, the ALMA Antofagasta Region Fund — financed by our partners AUI, ESO, and NAOJ — offers competitive grants for projects proposed by the communities themselves. This fund has helped build local infrastructure, improve healthcare access, restore roads, install solar panels, develop community-based tourism, and more. In 2023 alone, nearly USD 390,000 was granted to local initiatives. Since its creation, the fund has invested more than USD 6.3 million in the region’s development.

This ongoing work is further strengthened by ALMA’s presence on the ground. In July, Carolina Fuentealba joined as Community Liaison, reinforcing our direct connection with the local communities. For Catalina Margulis, this is part of ALMA’s long-term vision: “Our role is not just to implement projects, but to build long-term relationships based on respect and active listening to what the communities need and value.”

Understanding this work is key to appreciating how ALMA engages with its surroundings. It is a fundamental part of our operations — and a concrete example of how astronomy and local development can move forward together, honoring the history, culture, and identity of the territory we share.
