National Water Security Definition

Sources: (UN-Water, 2013)

Water security is defined as the capacity of a population to safeguard sustainable access to adequate quantities

• f acceptable quality water for sustaining livelihoods,

human well-being, and socio-economic development, for ensuring protection against water- borne pollution and water-related disasters, and for preserving ecosystems in a climate of peace and political stability. (UN-Water, 2013)

• 5. Change of rain volume, frequency of the

monsoon and intensity of storms are significant factors for drought and flood in South and Northeast regions. Currently, solutions for those problems change to use of non-structure measures.
