“Next week we’ll continue with a parallel program so people can keep visiting us. We’re pleased with the results of this main program; we had more than 15 international mayors, 22 national mayors, and 45 international delegations from other cities. We had six thematic areas with some wonderful global partners,” said Cristina Zambrano, executive director of ACI Medellín.

This Monday, October 5, at 4:30 p.m. at the Botanical Garden, the Colombian Botany Congress will open; its presentations will take place from the 6th to the 9th of this month at Plaza Mayor. In addition, on the 8th and 9th, the Sixth International Conference on Urban Trees will be held in the Restrepo Hall at the Botanical Garden.
These events will have an impact on the city’s economy. It is estimated that tourists attending Climate Week Biodiversity 2026 will generate approximately $2.2 million in economic impact, including spending on lodging, transportation, food, shopping, and recreational activities, among other things.
The main program, which took place from September 28 to October 1, brought together more than 6,000 participants from 30 countries, including mayors, ambassadors, representatives of international organizations, academics, businesses, social organizations, and experts. Among the announcements was the confirmation of a $300 million loan from the Development Bank of Latin America and the Caribbean (CAF) for the San Antonio de Prado cable car system, announced by Mayor Federico Gutiérrez Zuluaga.
In this context, international agreements and commitments were reached to advance the protection of nature. Medellín, Miami, and Bogotá signed the Declaration on Natural Areas, outlining actions to protect, maintain, and expand urban and peri-urban natural areas and to strengthen coordination in preparation for the IUCN World Congress on Protected and Conserved Areas, to be held in Panama in 2027.
In addition, Medellín signed the Grand Territorial Pact for Water Security, together with Cuenca Verde and other local stakeholders. The event is organized by the Mayor’s Office of Medellín, in partnership with Impact Hub Medellín, Fundación Socya, the Climate Week Network, and ACI Medellín.
