*!e ./D, is responsible for implementing t!e disaster mitigation capacit+ building

component and see4s to reduce t!e vulnerabilit+ of population and economic activities to

natural !azards) As a result- t!e ./D, includes a !azard vulnerabilit+ assessment

component)

*!e !azard vulnerabilit+ assessment component re5uires t!at critical facilities be

identified and collect statistic data on t!eir disaster !istor+ 0D2- structural 0S and

operational vulnerabilit+ 0O) *!is data is to be entered into a database- and integrated

into a /6S database) *!e 4e+ la+ers in t!e /6S database are !azard vulnerabilit+ maps

prepared b+ specialists in different areas suc! as (ind- droug!t 0Nevis onl+- storm surge-

floods- coastal erosion- and inland erosion 0St) 7itts onl+) *!ese la+ers are to be used to

assess t!e locational vulnerabilit+ : of critical facilities) Ot!er spatial la+ers of features

could be also included suc! as agricultural land- ma;or roads in future vulnerabilit+

assessments)

*o define t!e best met!od to use during t!e assessment- t!ree main topics !ave been

ta4en into consideration&
