Jakarta, “the sinking city”, is the current capital city of Indonesia. Located on the Java Sea, this coastal city is home to nearly 30 million people within the greater-Jakarta area. Jakarta has grappled with water management issues for decades, leading to several current day water-related crises. Access to a reliable, potable water supply is extremely limited as there is a significant disparity between those with piped water access and those without. Citizens without piped water access have consequently relied heavily on groundwater and have dug thousands of unregulated wells as a result. This has led to a second water crisis – the chronic overextraction of Jakarta’s underground aquifers. Land subsidence is of the utmost concern as this sinking city is placed at high flood risk from the surrounding ocean. Approximately 40% of Jakarta now lies below sea level as a result and predictive models suggest that the entire city will be underwater by 2050 (Gilmartin, 2019). Compounding these problems, the climate crisis has led to significant sea level rise as glaciers and ice caps continue to melt (Intergovernmental Panel on Climate Change, 2019; Lindsey, 2022). As the city of Jakarta continues to sink and sea levels rise, millions of citizens within Jakarta are at extremely high risk of flooding, particularly during monsoon season. Thousands of residents have already been forced to abandon their homes in search of improved conditions and higher ground (Garschagen et al., 2018).

Claudia Ruz Vargas is a civil engineer, graduated from the University of Santiago, Chile, with an international master’s degree in Groundwater and Global change. Her master thesis focused on groundwater modelling for recharge and saline intrusion risk assessment under climate change scenarios, in Cape Verde. Claudia has six years of work experience as a project engineer and researcher. She is currently a researcher at the International Groundwater Resources Assessment Centre (IGRAC), where she is involved in projects of high impact on the groundwater sector. In this interview, we talked to her about her career path, and how she has contributed to an improved and more sustainable management of groundwater resources, at a regional and global levels.
