This report contains the scientific studies that underpin the immediate and substantial actions needed to increase the adaptive capacity of Galápagos’ ecosystems and the people that depend on them. Adapting to climate change is the only solution to ensure ecosystems and human societies can survive and maintain their well-being when exposed to climate change impacts. These studies will support the development of the Climate Change Adaptation Plan for the Galápagos Islands, an initiative of the Ministry of Environment’s Climate Change Undersecretary, integrated into the National Climate Change Strategy of Ecuador.
