Extremely High Risk of flooding is projected especially for areas along major rivers, Areas which will face High Risk are concurrence to those with extremely high risk

Figure 6 Flood Risk Areas based on Scenario SRA2 in 2025-2030 5.1.3 Drought
Drought can be defined in many ways such as from perspective of meteorological, hydrological, agricultural etc. The eastern part of Indonesia is vulnerable to meteorological
drought. However, drought risk is particularly high in areas with high population numbers and density like Java-Bali. Drought can cause disaster, however, there is also potential for
economic opportunities especially for the sea-fishery sector. Findings from the drought risk analysis are as follows:
1 Extremely High risk areas are stretched out over small areas of the Central Java, Northern Sumatra, and Nusa Tenggara; 2 High risk areas are found in large parts of Central
Java, Sumatra, and Nusa Tenggara.

Strategic Issues for the Water Sector
As a result of the risk analysis, the following issues have to be addressed in order to successfully adapt the water sector to climate change:
1. Maintaining the balance between water availability and demand water balance. 2. Sufficient water infrastructure and the provision of alternative water sources in certain
areas. 3. Availability of data, technology and research as a basis for water resource management.
4. Reduction of vulnerability and risk from water shortage, flood and drought. 5. Finding of synergetic solutions for cross-sector issues with agriculture, forestry, health,
energy, and industry sectors. 6. Integrated water resources management and flood control.
7. Water conservation based on innovation, community participation and local wisdom. When addressing these key issues, the demands for water for domestic, urban and industrial
use have to be balanced. In order to ensure this, the following approaches should be pursued: 1. Prioritizing water demand for domestic use, especially in regions with water scarcity and in
regions of strategic importance. 2. Controlling the use of ground water and enhancing the use of surface water for water
17
supply. 3. Intensifying the development of water storages for water supply and optimization and
maintenance of existing resources. 4. Encouraging involvement of the private sector for financing the development of water
infrastructure. Moreover, the performance of water resource management must be improved by:
1. Encouraging the acceleration and completion of implementing regulations of the Law No. 7 of 2004.
2. Enhancing the capacity to communicate, cooperate, and coordinate between institutions involved in water resource management.
3. Building the capacity of institutions involved in water resource management and increasing community empowerment and participation at local level.
4. Nurturing initiatives and increasing community participation in water resource management.
5. Implementing water resource management by partnership between government and community.
