Natural and human-made disasters are common throughout the world. Disasters continue to occur without warning and are perceived to be on an increase in their magnitude, complexity, frequency and economic impact. Hazards pose threats to people and assume serious proportions in the under develop countries with dense populations. Disaster loss is on the rise with grave consequences for the survival, dignity and livelihood of individuals, particularly the poor and hard-won development gains. Disaster risk is increasingly of global concerns and its impact and actions in on region can have an impact on risks in another, and vice versa. This compounded by increasing vulnerability related to changing demographic, technological and socioeconomic conditions, unplanned urbanization, development within high risk zones, under development, environmental degradation, climate variability, geological hazards, competition for scarce resources and the impact of epidemics such as HIV/AIDS. Waterborne/ contamination and others points to a future where disasters could increasingly threaten the world economy and its population and the sustainable development of developing countries.
