2. The challenges of climate change Mountains, physical aspects It is expected that future climate warming will be particularly pronounced in cold areas such as mountains. It is expected that future climate warming will be particularly pronounced in cold areas such as mountains. In contrast to how mountains appear to us, their ecosystems are fragile and highly susceptible to degradation and environmental changes.

4. The challenges of climate change Mountains, social aspects As well as the environments in which they live in, mountain societies are characterized by a marked complexity and vulnerability, traits that are enhanced in the context of climate change and high uncertainty.

7. The challenges of climate change Tropical mountains If the conditions and the predictions are critical to the mountains and its people in general, they are even more so for tropical mountains. If the conditions and the predictions are critical to the mountains and its people in general, they are even more so for tropical mountains. In Peru, reality and forecasts are not encouraging: in the last 30 years the glacier surface lost about 25% of its 3170 km² and as tropical glaciers are particularly sensitive to temperature increase, some estimates indicate that they could disappear altogether in the coming decades.

14. The Case of the Santa River Basin, Cordillera Blanca, Peru A case that illustrates the challenges of climate change is the Santa River basin, which rises in the Cordillera Blanca and runs to the Pacific Ocean through a deep valley between the Cordillera Blanca and her neighbor, the Cordillera Negra.

16. The Case of the Santa River Basin, Cordillera Blanca, Peru The Santa River goes trough many different provinces, covers 316 km and has an area of ​​ 14.954 km². If we consider that this area is equivalent to almost one third of the territory of Switzerland, we can get an idea of ​​ the challenges that may be involved in managing this territorial level.

The Case of the Santa River Basin, Cordillera Blanca, Peru The social context of the Santa River basin is very complex and is characterized by social diversity and low institutional, commercial and political integration.

19. Conclusions Existing capacities to respond to increasing climate variability only exist at local levels.
