METHODOLOGY ASSESSMENT

In general, the methodology and flow used in the study of the implications of climate change on water availability in PALI District can be seen in Figure 3. Water availability analysis using Geographical Information System (GIS).
The main hazard (H) of climate factor is temperature rise and rainfall difference. H or Vulnerability (V), H / V, are non-climatic components, such as population, and land use. R is risk, H is hazard, V is vulnerability, E is exposure, S is sensitivity, AC is adaptive capacity.
R is a function of H and V; while V is a function of E and S where E and S are multiplication vulnerabilities, while AC reduces vulnerability. Weighting is used to determine the values of H, V and R.
The trend assumptions are needed to show how changes will occur during the projection period. So that will emerge two assumptions, namely climate factor and non-climate factor.
Assumptions about future trends in climate factors are needed to limit the main stimuli of the components affecting the water sector in the future. While assumptions on non-climatic factors are needed to assess vulnerability of freshwater systems on climate change and compare the important relationships of climate change impacts on changes in climate and non-climate factors.
