Water issues in Indonesia

Although Indonesia enjoys 21 % of total freshwater available in the Asia-

Pacific region, many of the country’s water security issues are tied to its

rapid development and poor urban infrastructure:

Lack access to safe/clean water and sanitation

Many areas vulnerable to floods as a result of land-

use change and deforestation

Wastewater from industrial, domestic and agriculture

sectors contaminated both surface water and

groundwater supplies. This exposure greatly increases

human susceptibility to water-related diseases.

The dry season may become more arid, driving water demand;

while the rainy season may condense higher precipitation levels

into shorter periods, increasing the possibility of heavy floods

(effects of climate change)
