Who Pays?
Prabowo has called on the DKI Jakarta provincial Government to contribute significantly, leveraging it’s substantial budget. He suggested a 50/50 split between Jakarta and the central government, easing the burden on national finances. he even jokingly reassured a seemingly “tense” Minister of Finance, Sri Mulyani, about the funding arrangements.
international Collaboration: Open for Business
Indonesia is open to international collaboration, inviting companies from China, Japan, Korea, Europe, and the Middle East to participate. However, Prabowo stressed that Indonesia won’t wait for external assistance and will proceed using its own resources.
Expert Tip:
When considering international partnerships,it’s crucial to balance technological expertise with local environmental concerns. A thorough environmental impact assessment is paramount.
Potential Benefits: A Coastal renaissance?
Beyond protecting against flooding, the sea wall could unlock critically important economic opportunities. Imagine reclaimed land for progress, improved water management, and enhanced coastal infrastructure.

Time.news recently reported on Indonesia’s ambitious plan to construct a giant sea wall stretching from Jakarta to east Java, a massive $80 billion project aimed at protecting the nation’s coastline from the devastating effects of rising sea levels and land subsidence. But is this colossal undertaking a viable solution? To delve deeper into the complexities of this project, we spoke with Dr. Anya Sharma, a leading expert in coastal engineering and climate adaptation.
Time.news: Dr. Sharma, thank you for joining us. The proposed Jakarta Sea Wall is a truly massive project. What are your initial thoughts on the scale and ambition?
Dr. Anya Sharma: It’s certainly a bold move. The urgency expressed by President Prabowo regarding the threat to coastal communities in Jakarta, Semarang, Pekalongan, and Brebes is very real. The combination of climate change-induced sea-level rise with the alarming rate of land subsidence in Jakarta presents a critical challenge that demands immediate attention. A 500-kilometer sea wall represents a notable investment and an enormous undertaking, but the potential benefits in terms of safeguarding lives and infrastructure are compelling.
Time.news: The article highlights the importance of international collaboration. What specific skills or technologies could be notably beneficial from foreign partners?
Dr. Anya Sharma: Indonesia’s openness to international collaboration is strategic. countries like the Netherlands, with its renowned Delta Works, possess invaluable expertise in large-scale coastal defense projects. Japan and Korea also have advanced technologies in marine engineering and materials science. The expertise lies in developing durable, environmentally sensitive designs that can withstand the specific challenges of the Indonesian coastline.
Time.news: the article mentions an “expert Tip” about balancing technological expertise with local environmental concerns. Can you elaborate on why a thorough environmental impact assessment is so crucial?
Dr. anya Sharma: Absolutely. A project of this magnitude can have significant and far-reaching environmental impacts. Constructing the sea wall could disrupt marine ecosystems, alter coastal currents, and negatively impact fisheries. A thorough environmental impact assessment (EIA) is essential to identify potential risks and develop mitigation measures. this includes studying the potential impact on marine biodiversity,water quality,sediment transport,and coastal habitats. It’s not just about building a wall; it’s about doing it responsibly.
Time.news: Social displacement is another major concern raised in the article. What are some best practices for ensuring equitable compensation and community engagement in a project like this?
dr. Anya Sharma: Social displacement is a critical factor. Clarity and proactive community engagement are key. Before any construction begins, thorough consultations with affected communities are essential to understand their concerns and needs. Resettlement plans must be developed in close collaboration with the communities, ensuring fair compensation, access to option housing, and livelihood opportunities. The goal should be to improve the lives of the affected communities, not make them worse.
Time.news: The article draws parallels with coastal challenges in the US, particularly New Orleans. What key lessons can Indonesia learn from the US experience with coastal protection projects?
Dr. Anya Sharma: The New Orleans levee system serves as a cautionary tale and a valuable case study, though, it highlights the importance of robust coastal defenses, but also the need for continuous maintainance and adaptation. Coastal environments are dynamic. A sea wall built today might not be adequate in 20 years due to climate change acceleration. Regular inspections, upgrades, and adaptive management strategies are essential. Furthermore, relying solely on hard infrastructure like sea walls is often not the most lasting solution. Integrated approaches that combine engineered defenses with natural solutions, such as mangrove restoration and wetland creation, are often more effective and resilient in the long run.

Dr. Anya Sharma: Addressing land subsidence is crucial for the long-term effectiveness of the sea wall and the overall resilience of Jakarta. Land subsidence is primarily caused by the excessive extraction of groundwater. Implementing stricter regulations on groundwater extraction, promoting alternative water sources (such as rainwater harvesting and treated wastewater), and improving water management practices are essential steps. Without addressing land subsidence, the sea wall will eventually become less effective, requiring further costly interventions.
Time.news: The article calls the project a “Necessary Gamble?” Do you agree with this assessment? Are there alternative solutions that should be explored alongside the sea wall?
Dr. Anya Sharma: It’s a high-stakes endeavor, no doubt.While the sea wall could provide a critical short-to-medium-term defense, it’s not a silver bullet. I strongly advocate for exploring and implementing a portfolio of solutions, focusing on both hard infrastructure and nature-based approaches. Mangrove restoration, such as, can provide natural coastal protection, enhance biodiversity, and support local fisheries. Improving drainage systems,raising building foundations,and implementing early warning systems are also vital components of a comprehensive climate adaptation strategy. The key is to adopt a holistic and adaptive approach that addresses the root causes of coastal vulnerability and builds long-term resilience.
