Abstract
Under-served communities in developing countries are more vulnerable to impacts in natural resources caused by climate change. Variability in these resources has the potential to result in disasters. This paper describes a study undertaken by one NGO to assist two off-grid foster homes, BK and LW, in Kalimantan in addressing rainfall variability for their domestic and agricultural water supply. Two satellite rainfall datasets were considered: CMORPH and TRMM. Monthly totals were obtained from 2003 to 2010, and compared against meteorological data from the closest airport using Friedman’s test. Based on the results, the TRMM dataset was selected for analysis. Linear regression analysis was performed on the annual rainfall data at each foster home from 2003 to 2010 to analyse rainfall trends. The results for BK showed a marginal increasing trend (y = 20x + 3964), while LW showed an increasing trend (y = 180x + 2770). These results correlate well with reported observations, and the data reflected the El Niño drought in 2006 and 2009. Based on these findings and other studies to qualify alternative water supplies, BK will be encouraged to explore well water, while LW will be encouraged to expand rainfall harvesting.
