Freetown, as a tropical capital, used to feature a particularly rich wetland ecosystem on the coast, which remains to be considered a Ramsar or conservation site and therefore falls under the purview of the National Protected Area Agency (NPAA). Poor conservation strategies and a high demand for housing have seriously damaged the green portions of the city, and with that, increased the risk of inland and coastal floods.

We’re experimenting with new ways of generating and sharing audio content through social media. Please listen and share these two ‘Audiograms’ that were created from work produced during our recent Environmental Reporting Workshops in Freetown.
I’m pleased to have been part of the recent environmental reporting workshops organised by the Lost Freetown Collective (LFC) and Hirondelle USA, and hosted by Concept Multimedia. Led by co-director of LFC, Nazia Parvez, the workshops brought together Freetown-based journalists and media professionals to explore the theme: ‘coastal zone management and climate change.’
Mangrove forests form an integral part of coastal ecosystems and play a key role in climate change mitigation. Growing in tropical and sub-tropical tidal areas, such as estuaries and marine shorelines, their roots extend deep into the coastal sediment. They serve as effective natural barriers to rising sea levels and flooding, bearing the brunt of storm surges and preventing excessive sedimentation. According to Corcoran, Ravilious and Skuja (2007), mangroves also serve as major carbon sinks, reducing the amount of carbon dioxide in the atmosphere together with other greenhouse gases.
Recent incidences of flooding and localised landslides in Freetown have clearly indicated that Sierra Leone lacks the capacity to absorb the effects of such disasters. There is weak resilience, a low level of preparedness and inadequate adaptive capacity in the country to resist climate-induced natural disasters. Communities that are directly affected, including Susan’s Bay in Central Freetown, are increasingly experiencing adverse environmental conditions, especially flooding during the rains, and dwindling water supplies.
