Vulnerability is the common cause of the immense disaster risk present on the African continent. For decades the international community has been speculating about the causal and underlying factors which render communities vulnerable to the impact of disasters. In most instances the focus was on the hazardous impact of an event and the surrounding inability of the stricken to deal with the consequences.
The need for an integrated disaster risk reduction management strategy in North African cities : a case study of urban vulnerability in Algiers (Algeria)Author Djillali BenouarSource: Jamba : Journal of Disaster Risk Studies 1, pp 6 –18 (2006)More Less
For the North African countries, geological, environmental and technological hazards constitute a constant threat to human life and property, sometimes causing major economic losses and disruption. The rapid urbanization, development of critical engineering works such as dams, decaying building stock, implementation of various industries within and around the main cities, industrialization of cities with modern types of buildings and the large concentration of populations, with a heavy dependency on infrastructure and services, living in large cities and/or settling in hazardous areas, are matters of growing concern, as they contribute to heavier loss of life and seriously increasing the economic losses in future disaster damage. The environmental concerns and an increased official and public awareness of various hazards have, in the last decade, led to a rapid rise of interest in hazard and risk evaluations and thus in disaster risk management.

A growing population, economic and environmental losses due to natural or human-made disasters, provides the need for a systematic approach to the management of risks. It is generally accepted that a multi-disciplinary understanding of disaster risk management is required.
Use of satellite images to map flood extension around the city of Saint Louis in the Senegal River estuarySource: Jamba : Journal of Disaster Risk Studies 1, pp 25 –33 (2006)More Less
The traditional method of landsat satellite data combination and the gathering of important information made it possible to produce a Geographical Information System to monitor floods in the lower estuary of the Senegal River valley (Sandholt, I., Fog, B. & Fensholt, R., 2001). This technical approach is a powerful tool for combining important information for a better comprehension of the floods and the characterization of surface qualities on the estuary. By way of a multi-temporal approach, the study team established the qualitative and quantitative impact of floods on the various geographical objects, a detailed cartography of the land use and the surfaces flooded in 1998 and 1999. The study undertaken in Saint Louis made it possible to consider surfaces flooded in 1999, and to understand the extent of these floods compared to those of 1998. The constitution of a tool of decision-making aid makes it possible to have information relating to the extent of the flood, the scope of flooded surfaces and to detect the more exposed zones in order to establish a hierarchical map according to the percentage of exposure to the risk of the geographical objects affected by the floods (populations), road infrastructures and tracks, medical and social infrastructures and perimeters of cultures (agriculture).

Sub-Saharan Africa is stricken by a generalised HIV/AIDS pandemic that will only reach its peak approximately by the year 2022 (Whiteside, 2002:313). As was widely debated during the recent 2001-2003 Southern African Food Security Crisis, the pandemic contributes to vulnerability in various ways (De Waal, And Whiteside, 2003; Harvey, 2004). However, the link between HIV/AIDS and vulnerability in Africa has not yet been explicitly addressed from the perspective of disaster risk reduction (DRR), as opposed to informing post disaster interventions. This paper offers a preliminary investigation of how survey based vulnerability assessments, might be informed by HIV/AIDS considerations, if vulnerability to the effects of natural hazards such as droughts and floods is to be effectively mitigated.

The current thinking in the Disaster Risk Reduction field emphasizes assessment and reduction of vulnerability and especially social vulnerability as an important factor in mitigating the effects of disasters. In the process of emphasizing vulnerability, the role and complexity of social resilience was somewhat lost and at times minimized. For example, Terry Cannon and his colleagues include resilience as a factor of social vulnerability in a report to United Kingdom Department for International Development (DFID) (Cannon, Twigg and Rowell, 2002). The United Nations University, Institute for Environment and Human Security (UNU-EHS) delineates "Social Vulnerability" and "Individual Vulnerability" as working areas, but does not mention Social or Individual Resilience (Bogardi, 2006).
