Water scarcity issues and water related extreme climate events had detrimentally impacted Indonesia's National Development Goals from various perspectives including economic, gross domestic product, ecosystems and community welfare. The Eastern Islands of Indonesia have been identified as one of the most vulnerable area to extreme climate change impacts compared to other part of the nation with a vulnerability index of 0.68 - 1.00. The greatest threat of climate change in these areas is the changes in the intensity and patterns of rainfalls that caused prolong drought season. Sumba island is one of the regions within the area that is negatively impacted by the growing risk of water scarcity due to extreme weather and climate change.
The severity and frequency of droughts that lead to water scarcity pose a significant risk to the population of Sumba island. Women and children are forced to become 'water fetcher' who routinely walk more than ten kilometers only to collect water. In an acute stress situation, the locals have no choices but to consume the poor-quality water. Additionally, the locals rely strongly on freshwater to maintain their livelihoods as farmers or livestock raising. This situation becomes more complex during the drought season affecting not only the livelihood but the agriculture, crop harvesting, animals feeding, washing, bathing and sanitation etc. Jeeten Kumar (RDI Program Manager) along with three international research members from various institutions have secured a fund to conduct research on Fog-to-Water (FtW) solution as one of feasible options for area that suffers from extreme weathers. Traditional solar powered/ conventional water pump and water filtration might not the most meaningful solution to these low-income neighborhoods especially when there is no rain for prolonged duration, or the freshwater sources are not close at hand. Thus, we perceive that it is crucial to conduct an elaborate research on the feasibility of Fog-to-Water (FtW) solution in an extreme climate-stricken community of the Eastern Island of Indonesia with a case study at Mandahu Village, East Sumba Island.
