Water quantity

Water quantity is the timing and total yield of water from a watershed, and is measured by total yield and peak flow over a specified period of time (Neary 2002).

From Jakarta to Nusantara: Land subsidence and other pressing water challenges in a sinking mega city

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).

Water-ForCE Webinar: Water and Agriculture

During this webinar, we will be discussing water quality (run-off from agriculture, pollution of surface water for irrigation) and quantity of water (drought, extreme rainfall, groundwater level, soil moisture) to tackle the water and agriculture domains for the Copernicus Roadmap.
