Yuli Tri Suwarni in the Jakarta Post: Scientists at the National Aeronautics and Space Agency (LAPAN) have linked climate change to the gradually diminishing areas of rainfall in a number of regions across West Java over the last 100 years. LAPAN’s Atmosphere and Climate Applied Science Center head Thomas Djamaluddin said scientists had compared data in the first 30 years of the 20th century (1900-1930) and the last 30 years of the 20th century (1973-2002).Based on the data, heavy annual rainfall of about 3,200 millimeters was occurring regularly in West Java in the early part of the 20th century in Bogor and its surrounding areas, including southern parts of Garut and Tasikmalaya, and spreading as far east as Ciamis, which borders Central Java. However, data on the intensity of rainfall in the last 30 years of the century showed that the only area in the province that experienced regular intense rainfall was Bogor.
“Residents in West Java should respond by adapting to the new phenomenon because water supplies during the rainy season have gradually reduced,” Thomas told The Jakarta Post in Bandung. Average annual rainfall across West Java has also dropped from 2,500 ml in the early 20th century to 2,000 ml today.
Thomas said the significant drop in rainfall could also take place in other areas in Indonesia. “We have to analyze how much rainfall has decreased in other areas, so as to determine steps to be taken in accordance with conditions in respective areas,” said Thomas, the 11th LAPAN professor….
