Abstract For climate change it is important to develop understanding on the ways that variability in the climate is emerging at the local level, and the areas of water use likely to be impacted there from. It was in this context that this research, was undertaken to analyze the pattern of climate change and the likely implication to the availability of water in Upper Kabul River Basin. Upper Kabul Sub-Basin was selected for this study for the reason that this is the most populous area in the country and any variability in climate and water would mean livelihood impact to large population. This has also been the area where competing uses of water have been large. The study involved extensive review of literature on climate change and resulting uncertainties to water availability in Afghanistan and in other parts of the world. Alongside the literature review, analysis of hydro-meteorological data specific to Upper Kabul Sub-Basin was carried out to assess the pattern of variation and trends in temperature, rainfall and stream flow. The trend analysis of temperature, rainfall and stream flow was carried out by fitting regression models to observed pattern of rainfall, temperature and stream flow. The relationship between rainfall and stream flow over the River Basin was established and this was used in projecting the variability and uncertainty in availability of water in the Sub-Basin. A combination of statistical analysis is done to perform to infer future stream flows. The largest reduction in mean stream flows and rainfall is expected in the study area.
