In 2011, the Kilindini harbour, the largest port on the East coast of Africa, was drenched to remove excess silt threatening the facility at the cost of Sh7.7 billion ($60 million).
Recently, Kenya Ports Authority (KPA) Managing Director William Ruto announced the second phase of dredging to deepen the channel to minus 16 metres to accommodate big ships.
In Kilifi's Mtwapa area, the 600-year-old Jumba la Mtwana Ruins is on the verge of collapse due to the waves from the ocean linked to the effects of global warming.
The walls of the village built in the 14th century are falling into the ocean owing to the effects of erosion that scientists blame on increasing water levels.
"During neap tide, tidal currents of the Indian Ocean wash the lower parts of the mosque by the sea, eroding its foundation," said William Tsaka, Jumba La Mtwana Ruins curator.
Some walls of the ruins are precariously leaning and likely to collapse if not stabilised while some pits have deep cavities, making coral rags fall off the walls.
Mr Caesar Bita, an Underwater and Marine Cultural Research Scientist, said the poor state of Jumba La Mtwana Ruins is prevalent in most historical sites across the Coast.
"Our cultural heritage is facing serious threat from climate change which has seen unprecedented rise in sea levels. If not outright erosion by the waves, crushing and breakage by the sea swells, then it is buried by sea sands," said Bita.
He said the erosion has gone with its historical sites, tourist attractions, sacred sites such as kayas, farming grounds, and settlement areas.
In Lamu, the narrow creek at Pate Bay that divided the Island into two halves has been swallowed and it is now deep, allowing sailing ships to anchor. The eastern side of this creek has silted heavily, allowing mangrove forests to grow, covering the entire original anchorage.
However, in some areas along the Coastal beaches, the sea has receded, creating swathes of land, and in others, coastal foreshores have been eroded.
Perhaps, as some have predicted, in the span of human life, Mombasa island will sink or a vast majority of its land will be covered by the rising waters of the ocean. Along the beach, inhabitants have fled.
