Outlook on climate change adaptation in the Tropical Andes mountains
Mountain ecosystems enrich the lives of over half of the world’s population as a source of water, energy, agriculture and other essential goods and services. Unfortunately, while the impact of climate change is accentuated at high altitude, such regions are often on the edge of decision-making, partly due to their isolation, inaccessibili ...

Hydropower lights up the Tropical Andes
As we have seen, climate change will have a significant impact on water flow, thus affecting hydropower generation, which generates the majority of power in the region. In South America as a whole, hydropower generates a...

Climate change in the Tropical Andes
The clearest trend in the Tropical Andes is the increase in air temperature. The Tropical Andes are expected to experience some of the most drastic change in climate in South America (Urrutia and Vuille, 2009; Hijmans et...

The effect of El Niño on weather in the Andes
Changing seasonality is perhaps the most important change in precipitation patterns observed so far. In the south in particular, there are indications that the rainy season has become more intense and more seasonally con...

The Tropical Andes region
The Tropical Andes region is the area of the Andean Mountain range from their northernmost point at 11°N in Colombia until 23°S on the southern border of Bolivia (Cuesta, 2012). This definition is based on national borde...
