According to the World Factbook, Ghana’s coastline extends a total length of 539km and is generally low lying (≤ 200m above sea level).
Ghana abounds in a rich marine ecosystem with salt marshes, estuaries, mangroves and sandy beaches that play host to a plethora of luxurious resorts and attractive forts and castles built by the Europeans.
In spite of the great eco-tourism potential and flourishing investments in resorts along the coastline, Ghana risks totally losing out on these economic potentials.
Additionally, it may lose the productive human capital as frequent high tides continue to threaten and sometimes ravage human settlements along the coast.
The South-Eastern coastal communities have become prone to tidal flooding in recent decades with Keta, one of the main European ports in the days of the transatlantic slave trade significantly lost to the sea.
This phenomenon of frequent tidal floodings in coastal ANLO and ADA, has, however, not been explained by any purely scientific oceanographic case study of the areas in question.
The Ghana Oceanographic Data Centre (GODC) is described as the hub of Ocean Data and Information, yet has never made available useful and timely information (i.e. tidal warnings) to the people of Keta, Srogboe, Whuti, Atorkor, Dzita, Akplorwotorkor, Ƒuveme, Adã and Gbegbese (Dansoman Beach).
So I ask; is there a working collaboration between NADMO, GODC and the Ghana Meteorological Services Department?
The tidal flooding of seven coastline communities in Anlo, on Sunday, 24th April, 2016, which left hundreds of people homeless, was accurately predicted in several Gulf of Guinea almanacs and published on http://www.tide-forecast.com/locations/Anloga/tides/latest., but this valuable information could not be disseminated by the mandated institutions, for reasons unknown.
Obviously, Ghana lacks Tidal Warming Systems that could help advance human security on the coastlines and to also serve as one of the country’s responsive approaches to climate change risk management.
The installation of interactive tidal warning systems such us outdoor digital tide Clocks, when constantly and their proper maintainability will greatly help coasters to always salvage critical items in times of rising sea levels.
Past and present governments continue to invest in sea walls such as the popular Keta Sea Defence Wall and the ongoing US$ 11.4 million Atorkor-Dzita-Anyanui Sea Defence Project and the US$ 39.9 million Sakumono Sea Defence Projects.
However, recent events in Srogboe, Whuti and Atorkor, where sea defence walls have been constructed, left many in shock. In spite of the sea defence walls, the floods ran over them into homes and across the streets defeating the purpose of hard engineering.
In view of these facts, the need for HIGH WAVES WARNING SYSTEMS cannot be over-emphasized.
As the world continues to see growing roles of regional bodies in humanitarian action, ECOWAS must also consider the installation of a regional Tsunami Warning System (TWS) as part of its climate change adaptation strategy.
