COMMENT | November flood: Strategies to prepare and mitigate it

COMMENT | Continuous alerts and warnings are being issued by Met Malaysia, Selangor menteri besar Selangor and the prime minister regarding impending storm surges and floods forecasted to start from Oct 3, 2022, till early next year. 

It was reported that six states are expected to be lashed with heavy rains, with Kelantan, Terengganu and Pahang predicted to experience heavy monsoon rains from November to December while Johor, Sabah and Sarawak are expected to face the same from December to January 2023. 

Malaysia is expected to experience floods worse than the present record of December 2021 and this in particular is causing grave concern to the rakyat. 

Reflecting back on the highest death toll recorded and extensive destructions to properties, infrastructures, businesses and the economy in last year’s flood, many are wondering how and what is the federal and state governments doing to prepare better for this impending hazard which hopefully will not turn into a terrible catastrophe.

Lack of an early warning system, and delayed and inefficient rescue and response were cited as major causes of these deaths and destruction.

Climate crisis, amongst others, is creating serious havoc on the global climate,  resulting in an increase in the frequency, spatial extent, duration and severity of weather events; including flash floods, storm surges and an increase in sea level rise (SLR). 

In the December 2021 flood, the government had responded that it was ill-prepared for the flooding and in particular that which affected Kuala Lumpur as the Federal Territory had not been flooded since 1971.

Reflecting on this response and the anticipated worse flood in November, the residents of Kuala Lumpur had requested the government to share its plans for flood preparation and mitigation.

Receiving inadequate response from the relevant authority, prompted the KL residents to file a lawsuit to compel the Kuala Lumpur City Hall (DBKL) and the Federal Territories Ministry to provide further information on its flood mitigation measures. 

A positive response was received from the FT minister inviting KL residents to meet and discuss on this issue. 

There is indeed genuine cause for concern by all Malaysians regarding how well is the nation and states preparing for this calamity. 

Response from government 

On Jan 20, 2022, Prime Minister Ismail Sabri Yaakob remarked “bad weather warning issued but ignored”. 

Shah Alam police chief Baharudin Mat Taib had advised people to look out for themselves and their families and always be prepared for any eventualities due to flooding.

He had also remarked “we also  need the cooperation of the people to channel flood-related information or the  discovery of drowning victims to us” and had provided fixed line telephone  numbers of the Shah Alam district headquarters operations room at 03-5520  2000 or 03-5520 2022, for the public to call and contact with such information.

In March 2022, the Environment and Water Minister Tuan Ibrahim Tuan Man informed that the Irrigation and Drainage Department (DID) implemented a flood forecast and warning programme which aims to provide early warning to agencies responsible for disaster management and the public and that sirens will be sounded when the water level exceeds a certain threshold value to give early warnings to locals with flood forecasts as early as seven days and warnings as early as two days provided to locations expected to face flooding. 

On June 11, 2022, Minerals and Geoscience Department (JMG) director-general Hisamuddin Termidi informed that an early warning system (EWS) to detect geological disasters, especially debris flow, developed by JMG  in partnership with Universiti Teknologi Malaysia (UTM)has been installed at the Titi Hayun Recreational Forest to provide advance warning in the event of a  water surge phenomenon in the area. 

On Aug 9, 2022, the Forestry Department director-general Indera Mohd Ridza Awang announced that the department will install early warning systems at 20 forest eco parks at risk of landslides and water surges.

The system will be installed at strategic locations in areas at risk of water surges and will issue a warning siren when such incidents occur to warn visitors to get out of and evacuate the high-risk areas increasing their chances of survival.

On Sept 7, 2022, the Fire and Rescue Department reported that there are 73 dangerous locations nationwide that are at risk of being hit by a  water surge with the highest numbers in Kedah - 20 high-risk areas - followed by Selangor with 17 high-risk areas. Terengganu has nine such locations followed by  Perak and Johor (with six each), Kelantan (five), Pahang (four) Sabah and  Sarawak (each two), Perlis and Negeri Sembilan (one each).  

On Sept 12, 2022, Ismail Sabri announced that the central disaster management committee meeting has agreed that the district disaster management committees (JPBD) chaired by the district officer are to be immediately activated to face the northeast monsoon and floods and their role in all disaster locations strengthened.

The PM highlighted that this is because the JPBD has an important function to carry out rescue works and aid delivery at disaster locations while the National Disaster Management  Agency (Nadma) and the state disaster management committees (JPBN)  coordinate at the central and state level respectively.

On Sept 19, 2022, the Selangor government listed 307 flood risk areas in the state.

Victims of flood

a) Flood victims nationwide from December 2021 flood 

Inspector-General of Police Acryl Sani Abdullah Sani reported on Dec 27, 2021, that the state with the highest number of deaths was Selangor with 25 victims (17 men and eight women), followed by Pahang with 20 (14 men, four women and two boys) and Kelantan three (two men and a girl).  

Amongst these victims in Selangor included, among others, as reported by Shah Alam police chief, two men discovered on Dec 19 at 4.15pm and 8.03pm at the traffic light of Kemuning Utama in Section 33 and near Alam Idaman in Section 22, a man found at the  Section 25 disaster operations centre, a man found in a drain underneath Elite  Highway near MSU, two women found in a Section 25 terrace house and a 78-year-old father and his 48-year-old daughter found in a single story terrace house in Taman Sri Muda. 

Victims found in Pahang included a factory operator who had fallen off a motorcycle while attempting to ride through a flooded road and discovered  near a Chinese cemetery at Gambang, near Kuantan, a father and son swept  away by strong currents when wading through the flooded football field in Mentakab, Temerloh, four victims had drowned in the mudslide in Telemong, Bentong, three people including a six-year-old boy and the owner of the chalet have been swept away by a column of water at the Bobby Eco Camp resort  compound in Bentong and two occupants at a Janda Baik resort were found  drowned  

b) Victims of water surge at Gunung Suku in Simpang Pulai, Perak 

On May 15, 2022, the sudden surge of water and soil from a stream as result of heavy rainfall had swept away two hikers, part of a group of 29  hikers, who were hiking along a trail on the hill at Gunung Suku in Simpang  Pulai in Perak. In the following days, the search and rescue team found two body parts, believed to be from the victims. Perak  Forestry Department director Mohamed Zain Yusop remarked that the department will temporarily stop issuing any permits to enter the  forest reserve due to the dangerous situation arising from the present heavy downpours and thunderstorms.

c) Victims from floods in Baling, Kedah in July 2022 

In the July 6 flood, at least three people whose house was swept away by strong currents had died; a 53-year-old bedridden woman suffering from stroke and her 23-year-old daughter in law who was four months pregnant found in an embrace under a pile of logs, 100m from their collapsed house and the 14-year-old son of the later who was found not far away. Some news reported that this incident in Baling was  due to a burst reservoir 

Observation

From the above brief on flood victims, it is evident that floods result in the death of persons of different gender, age including vulnerable groups comprising children, women, elderly persons, and in a myriad of situations. 

The government’s great efforts in identifying 73 dangerous locations nationwide that are at risk of being hit by a water surge and early warning systems being installed in 20 forest eco parks at risk of landslides and water surges as well as warning signs posted in at-risk areas to warn public of danger is indeed laudable. 

In addition to flood victims found in recreational areas and eco-resorts, flood  victims were also found trapped at homes, swept away from collapsed homes,  swept away whilst wading through the flooded football fields, fallen into drains and  victims on motorbikes swept by strong currents 

Recommendation

The EWS should be a community-centred system that supports the last mile based on the end-to-end early warning system for flood forecasting (E2E-EWS-FF) a WMO framework to promote the enhancement of flood forecasting and early warning capabilities aligned with the Sendai Framework. (see Fig 1) 

Practical Action dovetails that reaching the “last mile” focuses on communicating risk effectively to the people most vulnerable to disasters and that in order for people to protect themselves from hazards, they need to receive information, understand it, and be able to act on the information.

However, there are many complex barriers faced by vulnerable communities: when information is shared via text message, people without access to a mobile phone can’t receive the information; if the information is not communicated in local languages, or if technical or unclear wording is used, people who receive the information may not be able to understand it; and if people don’t know what actions to take, are afraid of losing their possessions, don’t have anywhere safe to go, or do not have decision-making power, they will not be able to act on the information. 

Thus efforts must be strengthened in improving the “last mile” of the chain of actions designed to reach people on the ground or the affected communities including the vulnerable groups such as women, children,  the elderly, the disabled, migrants and displaced populations. 

As evident from the diagram above, an early warning does not just stop at early warning dissemination but also requires decision support of relevant agencies receiving these warnings as well as critically the responses from both relevant authorities, the affected communities and the public. 

Early warning can continue to be disseminated via traditional communication channels of TV and radio but should be expanded to use modern communications channels such as the internet and social media to ensure alerts and warnings reach as wide a community as possible. 

In particular as the contact information of Malaysians and those residing in Malaysia are already recorded in the Covid-19 SMS platform, the government should use the same or similar channel to send flood alerts and warning as this would be more impactful than advising citizens to refer to MetMalaysia and other relevant websites.

It is imperative for authorities at the district, state and national levels to provide information to various stakeholders in addition to tourists to recreational parks covering persons inside homes, offices, schools, resorts and parks, in transportation hubs such as airports, ports, train station and bus stations and persons walking in open spaces and motorists in cars and on motorbikes/bicycles on the necessary actions and steps to be taken before, during and after the flood. International best practices on these include, among others, advisory offered by US Centre for Disease Control and Prevention (CDC),  National Oceanic and Atmospheric Administration (NOAA) and FEMA. 

Town hall sessions could be conducted to share more information regarding the impending disaster and gather queries from the public and respond to them accordingly.

Training and drills should be started soon to guide citizens and communities on ways to respond when faced with these hazards. 

It is vital for the government to provide hazard maps and hazard risk maps to the organisations responsible for disaster management and the public with detailed information regarding areas/locations potential of being impacted by hazards such as floods similar to that provided by the US FEMA in which these organisation and interested persons can key in their address or location and a  hazard map with details of the risk of flood illustrated on the map is generated.  

This detailed information is critical to guide organisations to make necessary preparations to enhance disaster management efforts and for the public to take the correct and timely action and response for their safety and survival. 

It is hoped that the presentation by Science, Technology and  Innovation Minister Dr Adam Baba to the prime minister this Thursday at MRANTI Park on the technology developed by the Malaysian Space Agency (Mysa) using satellites for data observation through the radar and optical methods in locations with frequent floods based on 10 years of experience which is intended to warn the government about flood hotspots when the monsoon sets in so that preparations can be made in advance, will include this service also to the public.  

With reference to related ministries’ announcement of the development of hazard maps of selected areas, it is imperative for the collaboration of relevant public and private stakeholders to develop a portal for the public to assess to gather detailed information regarding their area/location’s potential of being impacted by hazards including floods by keying in their address or location to guide Malaysians towards enhanced safety.

Disaster management agencies at national, state and local levels should have a variety of communication channels for those affected to reach them.  The present fix or landline would be overwhelmed during disaster preventing more to contact these agencies to seek help for rescue. 

The public should be encouraged to share details of the location, and condition of these hazards via various communications channels to help and support disaster management agencies to have more detailed information about the hazard via crowdsourcing as well as to provide rescue teams with locations of affected communities to facilitate and hasten rescue operations.  

In view that two feet of water could overturn vehicles and boats and that previous flood events had reported that food and other aid could not reach those affected as boats and lorries were overturned by the fast-moving flood waters, the government must embrace new technologies such as drones to locate flood victims as well as to send food and aid to them. It is encouraging that the Science, Technology and  Innovation Ministry has such plans in the pipeline. 

Disaster and responses to it should be introduced as a syllabus in schools even starting at the primary school level to prepare Malaysians to be familiar with these hazards and be better prepared to respond and react to them to enhance safety.
