Risks of water scarcity and flood threaten people unevenly across the region. In CSA, about 26%  of the population have no access to safe drinking water, and strong disparities prevail regarding its spatial distribution; for example, in Chile, 99% of the population have access, compared to 50% in Peru, 73% in Colombia, 52% in Nicaragua or 56% in Guatemala  . Inequalities can be further exacerbated by unregulated or privately owned water rights and allocation systems  . The most vulnerable people belong to low- income groups in rural areas and informal settlements of large urban areas  .
