People walk past coca leaf reading rooms at a market built on the edge of a cliff in the La Ceja area of the city of El Alto, Bolivia, on December 9, 2024. Nestled between the mountains at an altitude of more than 3,500 meters, La Paz is criss-crossed by more than 300 rivers and streams, making the soil unstable and severely affected in times of heavy rains that cause landslides. Nearly one in five registered properties are in areas of "high" or "very high" risk, according to the municipality, many of them in shanty towns. (Photo by AIZAR RALDES / AFP)
