The document outlines lessons learned over five years regarding sustainability decision-making at Galileo University in Guatemala, highlighting five gaps affecting effective action: disconnect between research and teaching, lack of multidisciplinary approaches, coordination deficits, insufficient partnerships, and time misalignment in addressing sustainability issues. It emphasizes the need for reform in educational curricula and increased collaboration between academia, government, and the private sector to tackle these sustainability challenges effectively. Recommendations include prioritizing identified gaps, fostering links between renewable energy and climate change, and supporting research activities to enhance decision-making and resilience against environmental vulnerabilities.
