Bolivia is a landlocked country located in central South America between the Andes and the Amazon. It is bordered by Peru, Paraguay, Brazil, Chile, and Argentina. Despite an abundance of water resources, water scarcity is a growing problem in parts of highlands and valleys. Temperature increases and climate variability are causing diseases, such as malaria and dengue fever. The country's vulnerability is exacerbated by the significant concentrations of Bolivia’s population living in fragile mountain ecosystems and expanding arid zones.
