Climate Change

Flooding in the East Coast

December has always been the monsoonal flooding season for Peninsular Malaysia’s northern East Coast states (Kelantan and Terengganu). This year’s flood is reportedly “extraordinary” as the rainfall intensity was 627mm in a day. This is the highest in 55 years. It broke the record of 608mm logged in Kota Baru in 1967.

By 21 December 2022, 32,089 people in Kelantan were displaced to relief centres. In Terengganu, at least 40,000 people were affected at the height of the disaster.

Also memorable were the year-end floods in 2014 - 2015 where over 200,000 people were affected and 24 killed. Over a period of three days (21-23 December 2014), a record-setting 1295mm fell, equivalent to 64 regular days of rain

These images show the 30-day accumulated precipitation and anomalies of the region from CPC Unified data. In the 30 days to 1 Jan 2023, accumulated precipitation on the East Coast was estimated at 900mm (see the red zones in the image on the left) which was 270mm above typical (see the blue zone in image on the right). These are very high readings. Kelantan is now preparing for a possible second wave of flood.

Note:

  • “Southeast Asia is globally considered one of the most vulnerable regions to climate change. Countries across the region will face rising sea levels, heat waves, floods and droughts, and increasingly intense and unpredictable weather events” (USAID, Jul 2022). The conversation is turning toward a fair approach to funding efforts on climate change.

  • In Khazanah Research Institute (2022) recent Climate Strategy report: "Nationally and locally, we should be focusing on climate adaptation measures: urban greening to tackle urban heatwaves, flood mitigation and better planning to minimise the impact of the great rains, mangrove restoration and engineering works to combat coastal erosion. These measures are not rocket science, we have the local expertise and technology to pull much of this off, unlike with energy transition measures. However, we need to tap into more national and international financing to bring these solutions online. It can be done. Think City in Penang has recently secured US$10 million in climate adaptation financing to tackle heat and floods."

    Comment: Although there is no specific mention of East Coast flooding and the cost of mitigation there, we should expect more focus on this to come.

  • Here are some recent initiatives by the Malaysia government for flood mitigation on the East Coast:

    • Under the 12th Malaysian Plan, RM9.19 billion was allocated for flood mitigation projects nationwide with Kelantan receiving RM1.3 billion for four projects and Terengganu receiving RM450 million for nine projects (TheStar, 2021).

    • In 2022, there will be 15 works to be implemented in Kuala Krai with an estimated cost of RM 1.1 million (TheMalaysianReserve, 2022).

    • 40 ongoing and planned flood mitigation projects in the East Cost for 2023. One of the major projects, the Sungai Kelantan Integrated River Basin Development Project (PLSB), is estimated to be at RM 2.156 billion (TheStar, 2022).

In our coverage at PalmTrack, we also monitor rainfall in the region. This has a focus on the core oil palm growing regions of Indonesia and Malaysia.

More Public Attention on Malaysia Flood and Climate Change

In December 2021, heavy rainfall had resulted in severe flooding in numerous areas within Peninsular Malaysia. Regarded as one of the worst flood disasters the country has seen in the recent years, the flood effectively displaced an estimated tens of thousands of residents and was further proof that Malaysia is not—and will not be—spared from the growing effects of climate change.

Malaysia has yet to forget the devastation the floods had caused—topic of climate change is becoming an increasingly important and popular one, particularly online. Accordingly, activists and environmentalists have taken the opportunity to highlight the gravity of the situation, oftentimes working hand-in-hand with the media as a platform where the public can be kept abreast about the matter.

Kini News Lab is one such platform and its most recent article is “When the Water Rises: A Malaysian Climate Change Story,” which described how climate change has adversely impacted the livelihoods, standards of living, and psychology of Malaysians across the country. The article also allows readers to see annual temperature and rainfall changes in various locations since 1952.

A part of the article also covered rising sea water levels, yet another threat Malaysia is facing as a direct result of climate change. In the worst case scenario for Malaysia, sea levels could very well rise up to 0.74 metres by the 2100 year, plunging low lying and coastal areas underwater.

Khor Reports did a short review several years ago comparing between the best and worst case scenarios for key areas where the land is at risk of coastal flooding by 2050: Land Reclamation Projects and Sand Dredging/Mining Sites in Peninsular Malaysia ver. Oct 2019.

We also wrote a piece on the politics of floods, with criticism about land development coming from businessmen and bureaucrats interviewed: Malaysia - the Political Economy of Land Development (or the Politics of Flood). While attention on coastal and flash floods is gaining attention, we would also like to highlight the issue of ground water flooding that can worsen flood woes (see box below).
