The water availability risk relates to water shortages. The following map and graphs detail values of water availability and water demand per sector using the 'Falkenmark Index'. Also known as the 'water stress index', it is one of the most commonly used measures of water scarcity. The index works by linking water availability risk to the quantity of water available to the population of the region indicated.
Salinity and bacteriological contamination impact the quality of drinking, irrigation and bathing water. Total Dissolved Solids (TDS) measures the quality of water for drinking and agriculture based on the level of salinity. The group of organisms found in the intestines of animals and humans called Escherichia coli (E. coli) is one of the most used measurements of bacteriological contamination of water. The presence of the bacteria indicates that human or animal feces may be present in the water and could contain other potentially harmful organisms that could cause illness.
Internally displaced persons (IDPs) are "persons or groups of persons who have been forced or (IDPs) obliged to flee or to leave their homes or places of habitual residence, in particular as a result of or in order to avoid the effects of armed conflict, situations of generalized violence, violations of human rights or natural or human-made disasters, and who have not crossed an internationally recognized State border" (source: IOM).
