Imagine a peaceful coastal village, with lush green rice fields stretching wide, children running and playing, and gentle waves forming the soundtrack of everyday life. That was the past of Loireng Village in Demak, Central Java. Now, it is only a memory. Tidal floods have arrived, coastal erosion has advanced, and the village has changed forever.
Regionally, data from a 2021 Geomatika Journal publication by Indonesia’s Geospatial Information Agency (BIG) shows that coastal erosion along Central Java’s shoreline has increased significantly. Since 2015, seawater has steadily taken over the land. Rice fields have turned into lifeless ponds, their brackish water no longer suitable for cultivation. Farmers have been forced to become fishers or aquaculture farmers—not by choice, but out of necessity. This shift is not just about changing jobs; it is about losing a way of life passed down through generations.
This transformation is a survival strategy amid worsening conditions. For agrarian communities who have long depended on the land, adapting to maritime livelihoods is far from easy. They must start from scratch, face uncertainty, and struggle to endure even when the future looks bleak.
Development That Comes at a High Cost
The Sayung–Semarang toll road project, which is only 30% complete, has blocked river flows, making flooding a regular occurrence in Demak. Yet guidelines issued by Indonesia’s Ministry of Public Works and Housing (PUPR) in 2016 already warned that major infrastructure projects like toll roads can increase flood risk if drainage systems are not designed using sustainable principles.
In Loireng Village, floodwaters now linger for months and have become part of daily life. Water that once flowed freely is now trapped, turning the village into a giant bowl filled with stagnant water. Even during celebrations such as Eid al-Fitr, residents must mark the holiday with their feet submerged in floodwater.
Industrial waste from nearby factories has worsened the situation. With pollutants discharged into rivers, water quality has deteriorated, deepening an already critical environmental crisis. Data from Central Java’s SDGs Indicator Metadata Service shows that hazardous waste (B3) management remains a serious challenge in the region. Communities that should be environmental stewards instead become victims of a system that prioritizes large-scale capital interests.
Meanwhile, mangrove ecosystems—the coast’s natural defense—have been cleared to make way for the toll road. A total of 42.6 hectares of mangroves have been lost. As a result, erosion has intensified and villages have grown more vulnerable. According to the International Union for Conservation of Nature (IUCN), mangroves play a crucial role in climate change mitigation and coastal protection.
Ironically, despite the massive impacts, residents have received no compensation. Limited information and poor public consultation have left communities to simply accept the consequences without understanding what the future holds. A 2022 study from Gadjah Mada University (UGM) had already highlighted the importance of community participation in sustainable development planning to prevent inequality and social conflict.
Remaining Hope from the Coast
Amid the climate crisis and mounting ecological disasters, hope has not entirely faded. Communities still believe that fairer and more inclusive development is possible. Infrastructure is important, but it must be built with respect for environmental carrying capacity and the needs of local communities. Without that, development becomes a ticking time bomb that harms everyone.
The pressing question is: Who is this coastline for?
Is it for a handful of powerful investors, or for the communities who have protected and lived from this land for decades?
This question goes beyond Loireng—it speaks to the future of Indonesia’s entire coastal regions.
Building without destroying is a challenge, but it is the only path toward a sustainable future. Coastal ecosystems belong not only to those with capital, but also to those who love and depend on them. A 2023 report by the United Nations Environment Programme (UNEP) emphasizes the importance of nature restoration for food security and community well-being.
This phenomenon reflects how the climate crisis is not just about the environment—it is also about social, economic, and moral justice. When infrastructure development ignores ecosystems, the resulting disasters are borne by the most vulnerable. The Intergovernmental Panel on Climate Change (IPCC) has warned that coastal areas in Southeast Asia will be among the hardest hit by climate change without urgent action.
The story from Demak’s coast reminds us that every action carries consequences, and the choices we make today will shape our future. Watch the documentary DEMO(k)RAS(i) – Lansekap 2 on Madani’s YouTube channel to witness firsthand the struggle of Demak’s residents. Together, we can be part of the solution to the climate crisis. 🌏
