Mangunharjo and Mangkang Wetan are two villages in the Tugu District of Semarang City, located in the northern coastal area of Central Java. Situated on the edge of coastal areas facing the Java Sea, the villages frequently experience tidal flooding.  

During the rainy season, or when tidal waves rise and strong winds blow, the villages are inundated by floodwaters. Sometimes, the flooding reaches the chest height of adult people, making children particularly vulnerable as the environment around them becomes unsafe for playing or even going to school. 

Modern development exacerbates tidal flooding 

In the past, the coastal areas of Semarang were dominated by agricultural land and surrounded by mangrove forests. However, with the onset of modern development, excessive exploitation and land conversion into industrial and residential areas have placed a heavy burden on the coastal area.  

The expansion of industrial areas causes land subsidence and the loss of natural barriers, as mangrove forests have been deforested. These issues then triggered coastal erosion and tidal flooding, harming the well-being of the local communities living nearby, including children.   

Children vulnerable to tidal flooding’s impact  

Living in the midst of a tidal disaster-prone area, children are the most vulnerable group affected by these conditions. When tidal flooding occurs, inundated houses, roads, and even schools disrupt their studies, hinder their way to school, and limit their freedom to play around.  

“When the tidal flood high, there many students who cannot attend the class for days because their homes inundated with flood as well as the access from their homes to school,” Slamet, the headmaster of Mangkang Wetan 01 Elementary School revealed. 

Slamet believes that coastal environmental protection should be taught to children from an early age to prepare them with the knowledge and skills needed to mitigate the impact of tidal flooding and reduce its severity. 

Trees4Trees initiated a coastal protection and mangrove education at school  

To provide children in both villages with essential knowledge on coastal protection and mangrove conservation, Trees4Trees organized an educational event through its Trees4School program. Coinciding with National Children’s Day on July 23rd, the event was held at Mangkang Wetan 01 Elementary School. 

The event was also part of the Trees4Trees Planting Festival, held in June 2024, where 2,000 mangroves and 100 coastal pine trees were planted in the Mangunharjo coastal area. This initiative supports the local community’s efforts to restore mangrove forests as natural barriers against tidal flooding. 

“Most of the children in Mangunharjo and Mangkang Wetan villages attend this elementary school. Since this area is prone to tidal flooding and is surrounded by mangrove covers planted by the local community in recent years, we believe it’s important for children to understand the value of caring for mangroves as natural barriers for their homes,” said Slamet. 

In collaboration with the Lanang Wadon Storytelling community, Trees4School included a storytelling session about the superpowers of mangroves. The session highlighted how mangroves sequester carbon dioxide at a rate 10 times greater than other trees, help stabilize the Earth’s temperature to prevent the worsening of global warming, provide habitat for coastal biodiversity, and most importantly, protect coastal areas from storm, erosion, and tidal flooding, which the children experience annually. 

“Through the Trees4School program’s coastal ecosystem and mangrove education, we aim to instill an early understanding of coastal preservation in children. Previously, we planted mangroves along the shoreline, and by engaging children in interactive activities such as games, storytelling, and short films, we hope to inspire them to protect mangroves and coastal ecosystems. Healthy mangrove forests contribute to robust coastal ecosystems, safeguarding their homes, schools, and their parents’ livelihoods,” said Adi Gani, Trees4Trees Project Manager.
