Disaster Management?

Disaster Management?

The term “Disaster Management” has been described as follows:

Any event (happening with or without warning) causing or threatening death, injury or disease, damage to property, infrastructure or environment, or disruption to the community which exceeds the ability of the affected society to cope using only its own resources.

Disaster Management? ‘Disaster Management’ means a continuous and

integrated multi-sectoral, multi-disciplinary process of planning and implementation of measures aimed at:

•Preventing or reducing the risk of disasters

•Mitigating the severity or consequences of disasters

•Emergency preparedness

•A rapid and effective response to disasters; and

•Post-disaster recovery and rehabilitation.

.

DISASTER MANAGEMENT CYCLE:

Pre-disaster risk reduction phase Disaster impact

Response

Recovery Prevention

Mitigation

Preparedness

Post-disaster recovery phase

Implementation of strategies

Taking the inkling of the Disaster Management Act

into consideration there are four strategies that

must be followed:

Pre-disaster Risk reduction / Offensive approach

• Prevention strategy

• Mitigation strategy

• Preparedness strategy

Post disaster / Defensive

• Rehabilitation.

Purpose of Disaster Management The purpose of Disaster Management system is to provide structure and co-ordination for the pre- and post management of emergencies and disasters. This is in order to provide for an effective and efficient response that will:

Save lives;

Reduce risks;

Reduce suffering;

Protect property;

Protect the environment;

Reduce economic and social losses; and

Provide for the safety and health of all responders.

Disaster management plan

The District Disaster Management Plan has been developed. The plan makes provision for the following categories:

• Disaster Management Legislative Framework

• The function of the Disaster Management Centre

• Disaster Management Information Management System

• Disaster Management Strategy for Prevention and Mitigation

• Disaster Management Strategy for Emergency Response

• Disaster Management Strategy for Recovery

• Disaster Management Plan support strategies

• Disaster Management Implementation Strategy

• The Corporate responsibilities and the District Disaster Advisory Forum

The Council approved the Disaster Management Plan

Disaster Management Forum

A Municipal Disaster Management Advisory Forum is a body which stakeholders and relevant disaster management role-players in the area consult one another and coordinate their actions on matters relating to disaster management.

To coordinate disaster risk management preventative and response principles into Integrated Development Projects, this is of utmost importance to ensure a safe environment conducive to sustainable development and sustainable livelihoods for our communities.

To develop and implement coordinated preparedness, response and recovery plans to restore normality as rapidly and cost effectively as possible.

Task teams

• Four Task Teams have been established covering all the classes of possible hazards in Mopani guided by the vulnerability risk and hazard assessment.

• Natural hazards Task Team

• Communicable non communicable diseases (Biological hazards.)

• Technological hazards Task Team.

• Environmental degradation Task Team.

•Duties of Task Teams

• Task Teams are responsible for disaster preparedness plans, risk reduction plans, response and recovery plans and rehabilitation and reconstruction plans.

• The Task Teams are led by different members of the task team depending on the hazard

• For each Task Team there is a leading department and enabling departments.

Phased escalation Response Plan

Phase I: Routine Operations

This is the level of operation that the centre exists at on a

daily basis. It allows for the daily routine operations of the

Disaster Management Centre to be fulfilled, and only involves

the monitoring of reported incidents. The call taker designated

as the contact person.

Phase II: Enhanced Operations (Alert Stage)

Escalation of Operations to this stage occurs if an incident

is or could potentially grow beyond the capability of the

designated call taker and current resources to

cope. (Activation of the Task Team)

Phased escalation Response Plan

Phase III: Full Operation

This phase represents the escalation where the incident size

and complexity requires representation for the appropriate

Municipal, Provincial and other agencies and organizations

to support the operations. The number of staff and

the agencies represented will vary depending on the incident.

(Activation of the Joint Operational Centre.)

Phase IV: Catastrophic Operations

In this phase a major catastrophic emergency or disaster

has occurred that exceeds the capability of provincial and

local government to provide timely and effective response

to meet the needs of the situation.

Overview:

Floods January 2013 Giyani

Overview: Floods 2013 Giyani.

On the 16th of January 2013, the South African Weather Service submitted the following early warning message:

Early warning: SAWS “The South African Weather Service wishes to advise the public that there is a high likelihood of wide-spread heavy rains over North West, Gauteng, eastern Free State, KwaZulu-Natal, Limpopo and Mpumalanga from late Friday 18th January 2013 to Sunday 20th January 2013. These heavy rains will be caused by an intense low pressure moving in from Botswana.

As consequence of heavy rains, rivers and stream systems will begin flowing strongly. The danger of flash-flooding should be kept in mind. There have already been heavy rains experienced over parts of Mpumalanga and Limpopo earlier this week and rivers in these areas are running high. These two provinces run the highest risk for flooding this weekend”

Early warning: SAWS

The public are therefore urged not to try to cross rivers and streams that are in flood, irrespective of whether they are on foot or in a vehicle. People living in areas close to rivers or within flood plains must also monitor the rising water levels.”

Radio and local media

Through the Communication Manager,

Mopani District Municipality

Disaster Management Centre

immediately issued a warning to

communities via local radio stations

and local media.

Impact of the rain.

The District start to receive rain from the 15th January 2013, but no problems were reported until Saturday the 19th January 2013 and Sunday 20th January 2013. By this stage, the ground had become saturated and runoff resulted in rivers coming down in flood. The heavy rain also started to have an effect on some houses which collapsed when their mud walls absorbed too much water. Dam levels also rose sharply with the Nsami Dam rising from 7% to 159% by the fifth day of rainfall.

Joint Operational Centres

The District Disaster Management Centre activated the District Disaster Management Joint Operational Centre (JOC). All District Departments are represented in the JOC to coordinate all the activities and to inform the Provincial Disaster Management Centre.
