This document discusses the impact of future climate change and population growth on water availability in Kupang City, Indonesia. It notes that the population of Kupang City grew 3.19% annually to 658,346 people in 2012. Climate change models project increased temperatures and variable rainfall patterns in the coming decades. While climate change alone may not significantly impact water availability, the combined effects of climate change, population growth, and increasing water demand are expected to result in water shortages from April to October each year as demand outpaces supply. The conclusion is that integrated water resources management and conservation efforts will be needed to ensure adequate water availability for Kupang City in the future.

13. Conclusion
• From the results of the analysis, can be in the know that the effects
of changes in temperature and rainfall effect on increasing
evapotranspiration. The more the temperature rises then
evapotranspiration ride. While the rainfall showed that promote
increased rainfall runoff and discharge the year higher. So also with
the increasing population and the need for increased water
shortages caused high water in april to october. the general impact
of climate change did not affect the availability of water, but with the
increase in population and water demand increases, greatly affects
the availability of water in Kupang city
• with the results of the analysis increased runoff and discharge in the
watershed since the year 2013 to 2099. the increasing number of
people each year, the need for water also increased, by using water
demand scenarios of low, medium and high, combined with climate
change scenarios, the analysis of the results indicated that the
availability of water is more and reached 593.98 m3/second, but in
April-October there is a shortage of water to -49 m3/second. This is
due to the high water demand and population increase.
