Emergency: “Is a situation generated by the real or imminent occurrence of an event that requires immediate attention Disaster: “Is a natural or human-caused event which causes intensive negative impacts on people, goods, services and/or the environment, exceeding the affected community’s capability to respond” (key words) Presented on 7th July 2011 by Dr Saka M.J Dept.of EPID UITH sakamj1@yahoo.com Def. Con’td A disaster is a situation in which the community is incapable of coping. It is a natural or human-caused event which causes intense negative impacts on people, goods, services and/or the environment, exceeding the affected community’s capability to respond; therefore the community seeks the assistance of government and international agencies. An emergency is a situation in which the community is capable of coping. It requires immediate attention Presented on 7th July 2011 by Dr Saka M.J Dept.of EPID UITH sakamj1@yahoo.com Vulnerability Factor for Disaster Risk “Is the probability that loss will occur as the result of an adverse event, given the hazard and the vulnerability” Risk (R) can be determined as a product of hazard (H) and vulnerability (V). i.e. R = H x V Vulnerability: “Is the extent to which a community’s structure, services or environment is likely to be damaged or disrupted by the impact of a hazard” (key words) Tangible/Material (easy to see; value easily determined) People - Property –Economy –Environment – water, soil, air, Intangible/Abstract (difficult to see; value difficult to determine) Social structures, Cultural practices, Cohesion, Motivation Presented on 7th July 2011 by Dr Saka M.J Dept.of EPID UITH sakamj1@yahoo.com Vulnerability Contributing Factors Poverty People who are already in a depressed state are less able to recover. Some people are even more vulnerable, pregnant women, children and the disabled Population growth Population has grown dramatically over the past Decade Rapid Urbanization Growing concentration around the capital. For example, two-thirds of the Abuja population lives in AMAC, Transition in cultural practices Increase in sub-standard housing in more heavily populated urban areas. Changes in traditional coping mechanisms – declines in self-reliance, food conservation and preservation, warning systems etc. Environmental degradation As resources are consumed, vegetation cover removed, water polluted and air fouled, a country is more vulnerable to a disaster. Awareness & information When people and government officials are unaware or lack info.n about disaster management, they fail to take appropriate actions Civil Strife and unrest Resources are consumed, people are in a stressed situation, and transportation is restricted.

EMS are merely technological tools that are expertly used to improve and enhance the Emergency Disaster management (EDM) process. We will examine specifically the role that Geographical Information Systems (GIS), GIS;- tool for display of geographically-referenced information. Global Positioning Systems (GPS) and Remote Sensing Technologies play in disaster management. While these subjects are presented individually, it is important to note that in reality these technologies are usually deployed in an integrated manner. Presented on 7th July 2011 by Dr Saka M.J Dept.of EPID UITH sakamj1@yahoo.com Usefulness of GIS in Disaster Mgt. 1 To create hazard inventory maps: At this level GIS can be used for the pre-feasibility study of developmental projects, at all inter-municipal or district level. 2 Locate critical facilities: Proves information on the physical location of shelters, drains and other physical facilities. for planners in the early phase of regional development projects or large engineering projects. It is used to investigate where hazards can be a constraint on the development of rural, urban or infrastructural projects. 3 Create and manage associated database;- GIS is intended for planners to formulate projects at feasibility levels, but it is also used to generate hazard and risk maps for existing settlements and cities. 4 Vulnerability assessment: GIS can provide useful information to boost disaster awareness with government and the public, so that (on a national level) decisions can be taken to establish or expand disaster management organizations Presented on 7th July 2011 by Dr Saka M.J Dept.of EPID UITH sakamj1@yahoo.com GPS and Disaster Mgt The term global positioning system (GPS) is used to refer to the Global Navigation Satellite System (GNSS) developed by the US Dept. of Defence. GPS is particularly useful during disasters because it operates in any weather, anywhere and at all times. While it functions simply to give the location of the receiver, the level of precision of GPS makes it quite useful in disaster management. In many instances GPS data is integrated with GIS Presented on 7th July 2011 by Dr Saka M.J Dept.of EPID UITH sakamj1@yahoo.com Remote Sensing and Disaster Mgt. Remote sensing is the use of electromagnetic (EM) wave radiation to acquire information about an object or phenomenon, by a recording device that is not in physical or intimate contact with the object. As you read this material you are actually engaging in remote sensing; we do this so naturally that we seldom realize it. We could take this a step further - we use telescopes to view distant planets. We are definitely sensing objects remotely. In both cases the sensor is our eyes and the EM wave is light IS EM new to us (Yes/No) Presented on 7th July 2011 by Dr Saka M.J Dept.of EPID UITH sakamj1@yahoo.com Remote Sensing (EM) If the term EM waves seems new to you it shouldn’t. Everyday light, radio waves and microwaves and x-rays are examples of EM waves. EM waves transport energy and information from one place to another. They are used in cellular networks, microwave ovens, portable radios, x-ray machines and satellites systems Remote sensing in the context of disaster management usually refers to the technology that includes man-made sensors that are attached to aircrafts, or satellites. Instead of viewing a far away planet from earth, the sensing equipment is usually high above looking down at our ‘distant’ planet - earth. Distant in this context can mean just a few hundred feet overhead or miles above the earth’s surface (See Next Slide).
