Key Risk
• Economic loss and exacerbation of poverty due to
lack of irrigation, resulting in lower yield and crop
failure, which in turn can lead to malnutrition and
its related health risks.
• Increased infectious diseases due to lack of water
for sanitation.
• Death, injury and loss of other valuables.
• Risk of reversal of progress in reducing poverty
andmalnutrition.
• Displacement of population, causing unrest
elsewhere.
• Increased landslide risk (exacerbated by
deforestation and inadequate landmanagement).
• Damage to infrastructure, including hydropower
systems, economic loss.
• Loss of ecosystem services, such as carbon
sequestration and soil protection.
• Spread of pollutants from mining areas with
inadequate flooding protection, leading to health
and environmental risks.
Summary of key hazards, vulnerabilities and risks

Climate Hazards
Shift of seasons
• Change of
precipitation patterns
• Concentration of
rainy season
Floods
• Increase in annual
precipitation
• Changes in run-off
pattern
• Increase in frequency
of floods
Key Vulnerability
• Mostly in the Altiplano and southern Peru. Too much
precipitation.
• Communities lacking water management infrastructure to
store excess water for later use.
NB Rainfall (precipitation) does not fall uniformly across the
Tropical Andes. It varies from north to south and east to west.
Precipitation also varies from one season to another. While the
overall annual precipitation has remained the same, it is the
seasons of rainfall that are changing the most. During the rainy
season, precipitation is becoming concentrated in fewer rainy
days with a higher intensity.
• Areas already experiencing problems with flooding (mainly
Ecuador and Colombia). The north-western Tropical Andes
in and around Ecuador are predicted to see the highest
increase in precipitation.
• High geographic exposure of agricultural and farming land,
homes, property and assets, including physical exposure of
rural and urban populations to potentially flooded areas.
Urban populations are especially densely populated, rural
populations are often even less protected and the poorest are
the most vulnerable.
• Areas with inadequate flood protection and drainage
infrastructure.
• Ageing energy infrastructure located in downstream flood-
prone areas.
• Poor land management and spatial planning practices.
• Exposed mining facilities containing polluting substances.
• Insufficient governmental dedication to disaster risk
management.
