Flooding In Freetown, Sierra Leone – The Way Forward

Sierra Leone ranks 138 out of 172 in the World Index of Countries prone to natural disasters. Research by the World Bank suggests that drier dry seasons and wetter wet seasons are only likely to increase in frequency in Coastal cities; this ominous prediction came to pass on September 16th 2015 when Sierra Leone’s capital city, Freetown, was hit by unprecedented floods caused by torrential rainfall of 600 mm  in  only 5 hours; the normal average annual rainfall for Freetown is about 2,945 mm and the total for the wettest month, August, averages about 790 mm.

This paper is based on the experiences and effects of those devastating floods to highlight the challenges facing city planners, why and where it happened and lessons learned. The Government’s state of preparedness and resilience for such disasters as well as the role of volunteers in communities is also discussed. Recommendations of flood risk management approaches using best practices on flood protection, prevention and mitigation for Freetown is presented.

Drainage Control, a major factor in Disaster Management in Sierra Leone

This paper attempts to look at how drainage, properly designed and managed can be a major mitigating factor in damages caused by floods. With the looming climate change phenomenon making its impact globally, it is observed that several factors contribute to its adverse effects. These include weather patterns, Natural Resources Management, the degree of resilience and risk mitigation measures developed in the affected countries.
The design and maintenance of these infrastructural elements falls on city and town councils within which are engineers whose responsibilities have been subjected to other higher pressures and conflicting resource allocation needs. The engineer has the theoretical skills to control disaster, but in a developing economy, political will, community cooperation, financial and other factors come into play in the choice of the best solutions and these are generally not the original intention of the engineer.

Risk management for resilience of mineral sector-supported economies:
Perspectives for the Sierra Leonean case

Historically, mineral resource-rich countries have relied heavily on revenues from the mineral sector for their economic well-being. However, such resource-based economies tend to be vulnerable to a range of cyclical risks and sector-specific hazards. A realization of these risk events (incidents) often wreaks considerable adverse outcomes on the economy. In spite of this notorious vulnerability of the sector, resource-rich countries often do not prepare themselves suitably, rendering their economies fragile and unstable in the face of risk eventuation. In this paper, selected risk tools are used to demonstrate the nature and impact of unattended risk elements and hazards on the sector and economy. Generic solutions are offered to improve resilience of the sector and the economy. Policy-supported systematic risk management is recommended as a core requirement, founded on a diversified economy and a knowledge-empowered local human resource base.

Fibre Optic Broadband Connectivity: An overview of current Fibre Optic Terrestrial Network deployment in Sierra Leone and its relevance to socio-economic Development

In the past Natural Resources were used to determine the economic future of nations, but today, we live in a Digital Economy powered by broadband, whether it is Fibre Optic cables, Digital Subscriber Line (DSL) in our homes or mobile devices in our pockets. Broadband has become a key priority of governments, as an essential tool for empowering people, creating an environment that nurtures innovation, triggering positive change in business processes as well as in society as a whole.
In 2009, the Government of Sierra Leone approached the World Bank for support to participate in the Africa Coast to Europe (ACE) consortium in order to connect Sierra Leone to the rest of the world through submarine Fiber Optic Cable.

The intent of this paper is to give an overview of the current National Fibre terrestrial Backbone deployment as well as its relevance to our socio-economic development. It will also provide an insight into the concrete steps Government is taking to position the ICT sector as a critical pillar of the Economy.
