PREFACE
In general, Indonesia is heavily affected by climate change, more than
17,000 islands in Indonesia are affected by climate change, such as sea
level rise, rainfall changes and other climate-related disasters. The
21st century rise in surface temperature globally on all models is
projected to rise 1.8oC to 4oC (IPCC, 2007). The results of climate
change studies in Indonesia and South Sumatra show that the projected
temperature rise in Indonesia is about 0.7 ± 0.2 o C in every century
(Hadi, et al., 2011)
The availability of fresh water is projected to decrease as population
growth and water demand continues to increase which will affect millions
of people by 2050. One of the impacts of climate change is the declining
availability of water in some parts of Indonesia (Abdurahman &
Setiawan, 2010). Water demand in South Sumatra will increase by 30-40
percent in the next several decades as population increases, resulting
in a decrease in water availability (Abdurahman, et al., 2012).
The current climate change risk assessment at the district / city level
is currently limited to the water sector (Setiawan et al., 2012). In
order for the resulting adaptation strategy to be effective, it is
proposed a micro level approach that assesses vulnerability at the micro
level (Setiawan et al., 2010).
This study aims to assess the risk of vulnerability and hazard to water
availability in PALI, South Sumatera with micro-level approach. The
scope of vulnerability assessments for water availability studies in
this study included the development of conceptual frameworks and methods
for assessing climate risk in water supply study studies. In addition,
identification of data needs includes collection, analysis, and
synthesis based on the method used.
