The seawall is conceived as a critical intervention to mitigate these risks, providing a physical barrier against the encroaching sea and safeguarding the city's future. Jakarta's sinking, primarily caused by excessive groundwater extraction, has made it one of the most vulnerable cities in the world to the impacts of climate change. The over-pumping of groundwater depletes the aquifers beneath the city, causing the land to compact and subside. This subsidence is not uniform across the city, with some areas sinking at a much faster rate than others. As a result, the city's coastline is gradually being submerged, and the risk of flooding is increasing significantly. The rising sea levels, driven by global warming and the melting of polar ice caps, further exacerbate the problem. The combination of land subsidence and rising sea levels poses an existential threat to Jakarta, potentially displacing millions of people and causing immense economic damage. The Giant Sea Wall is designed to act as a protective shield, preventing the sea from inundating the city. By creating a physical barrier along the coastline, the seawall will block high tides and storm surges, effectively reducing the risk of flooding. This protection is crucial for safeguarding Jakarta's infrastructure, including roads, buildings, and essential services, as well as the homes and livelihoods of its residents. Beyond providing immediate protection from flooding, the seawall is also intended to create a more stable environment for long-term urban development. The enclosed bay created by the seawall will provide a sheltered area for port activities, allowing for the expansion of Jakarta's maritime infrastructure. The artificial islands planned within the bay will also offer new opportunities for housing, commerce, and recreation, contributing to the city's economic growth and development. The project is not just about building a physical barrier; it is also about creating a more sustainable and resilient city. The NCICD project includes measures to improve water management, reduce pollution, and promote sustainable development practices. These measures are essential for addressing the underlying causes of Jakarta's sinking and ensuring the city's long-term viability. The decision to proceed with the Giant Sea Wall reflects a recognition of the urgency and gravity of Jakarta's situation. While the project is ambitious and complex, it is deemed necessary to protect the city from the potentially catastrophic consequences of unchecked land subsidence and rising sea levels. The seawall represents a significant investment in Jakarta's future, a commitment to safeguarding the city for generations to come.
