Kasoa Hillsides Face Erosion Risk As Rainfall Intensifies

Residents living on the hillsides of Kasoa are facing increasing fears of soil erosion. Intense and unpredictable rainfall, linked to climate change, now poses a significant threat to their homes and livelihoods. What were once manageable seasonal rains have become powerful downpours. These storms wash away soil and carve deep gullies into the land. This erosion weakens the foundations of many buildings.

The problem is made worse by rapid construction on slopes. Many of these new constructions lack proper drainage systems. The removal of trees further contributes to the land's instability. For residents like Esther, who has lived in the area for almost 30 years, the situation has become more alarming. "Anytime the rains come heavily, we become scared because the water keeps removing the soil around our houses. We don’t know whether one day the land will collapse," she shared. Homes are expanding uphill, often without adequate measures to control water runoff.

Environmental experts warn that this type of development significantly amplifies erosion risks during extreme weather events. Vegetation, particularly trees, plays a crucial role in soil protection. Studies show that natural plant cover helps hold soil particles together. It also slows down the flow of surface water. Climate scientists confirm that severe rainfall events are becoming more common across West Africa. The Intergovernmental Panel on Climate Change (IPCC) notes that even with stable annual rainfall, storms now deliver more intense rain in shorter periods. This increases the likelihood of flooding and landslides.

Mason Enock Asumadu observes the growing impact. He states, "The water now cuts through the land very fast. Every heavy rain leaves new holes in the ground, and that shows the soil is becoming weaker." He also pointed to the loss of trees. "When trees were here, the roots helped hold the land. Now many trees are gone, so the water washes the soil away easily. We need to plant more trees again."

Officials at the National Disaster Management Organisation (NADMO) acknowledge the residents' concerns. They are increasing awareness campaigns and community education in at-risk areas. A NADMO official advised, "Climate change is contributing to stronger rainfall events, and communities living in fragile areas must take precautions to reduce disaster risks."

The Ghana Hydrological Authority is also calling for immediate action to prevent further damage. They emphasize the need for better drainage infrastructure. Improved land-use planning and stricter enforcement of building codes are also essential. Officials recommend large-scale tree planting and restoring vegetation cover. This will help stabilise the soil and reduce erosion.
