Question #1: Can you provide an overview of the impact of climate change in Malaysia in recent years and the specific challenges it has posed in terms of flooding?

Climate change is exacerbating flooding in Malaysia. The average temperature in Malaysia has increased by about 2 degrees Celsius over the past 50 years, causing more intense rainfall events. In addition, rising sea levels are making coastal areas more vulnerable to flooding. In recent years, Malaysia has experienced a number of severe floods, including the floods of 2021, which were the worst in the country’s history. These floods caused billions of dollars in damage and displaced hundreds of thousands of people. Flooding poses a number of challenges for the country, including loss of life and property, damage to infrastructure, disruption to economic activity, and increased risk of disease. Malaysia is already a flood-prone country due to its high rainfall and low-lying coastal areas. However, climate change is making the problem worse.

In light of Malaysia’s climate challenges, building and infrastructure professionals should take steps to better prepare for and mitigate the impacts of flooding. This includes designing and building flood-resilient buildings and infrastructure, and installing flood protection measures.

Wavin’s message regarding the urgent need to (re)act to climate change and build liveable cities is that climate change is a serious threat to Malaysia and other countries around the world. It is important to take action now to mitigate the impacts of climate change and to build cities that are more resilient to climate change.

Question #2: What measures have the Malaysian government implemented to mitigate flooding, and how effective have these measures been so far? 

The Malaysian government has introduced a number of financial investments to mitigate the impacts of flooding, including:

  • Reissuing tenders for six flood mitigation projects that had been announced in an earlier iteration of the country’s 2023 budget. This is expected to save the country RM2 billion (US$450 million) and accelerate the completion of these projects.
  • Allocating RM150 million (US$33.62 million) to the National Disaster Management Agency and RM50 million (US$11.16 million) to the armed forces, firefighters and paramilitary civil volunteer corps RELA to improve flood preparation efforts.
  • Establishing a RM10 million ringgit (US$2.23 million) national disaster relief fund and RM20 million (US$4.47 million) grant for local community associations in efforts to face natural disasters.
  • Providing a RM2 billion (US$450 million) financing facility from the central bank Bank Negara Malaysia to support sustainable technology start-ups and help small and medium enterprises implement low-carbon practices.
  • Increasing the allocation of funds for the Ecological Fiscal Transfer for Biodiversity Conservation initiative to state governments.
  • Allocating RM150 million ringgit (USD33.62 million) to spur the development of environmentally-friendly projects, including supporting the carbon market and reforestation efforts.

The Malaysian government’s revised budget for 2023 is the largest ever, at RM386.14 billion (US$86.23 billion), up almost 4 per cent from the original RM372.3 billion (US$83.13 billion) budget proposed for this year. This increase is largely due to the government’s increased focus on flood mitigation and sustainable development. However, these measures are not enough to completely eliminate the risk of flooding. It is important for individuals and communities to also take steps to protect themselves from flooding. For example, people can build flood barriers around their homes and businesses, and they can have flood insurance to cover losses in the event of a flood.

Question #3: In the context of the building and construction industry, how can proactive identification of solutions contribute to the resilience of building infrastructure in Malaysia against flooding; as in Indonesia, we see the same challenges with flooding and taking water from the ground?

By conducting risk assessments and identifying areas where buildings and infrastructure are at risk of flooding, preventive steps can be taken to mitigate these risks. For example, existing buildings can be retrofitted with improved drainage systems, or new buildings can be constructed using flood-resistant materials and construction techniques.

Proactive identification of solutions can also drive the development and implementation of new technologies and practices to make buildings and infrastructure more resilient to flooding. For example, new building materials and construction techniques can be developed to withstand the forces of floodwaters and to minimize the damage caused by flooding.

It can also help to raise awareness of the importance of flood resilience and encourage the adoption of flood-resilient practices in the building and construction industry, through education and training programs, as well as through public awareness campaigns.

In addition, innovative drainage designs, such as permeable pavements, green roofs, and rain gardens, can also be used to make Malaysia’s building infrastructure more flood-resistant. Retrofitting existing buildings with improved drainage systems can also mitigate flood risks. High-quality drainage pipes and fittings are essential components of effective stormwater management. Conducting regular assessments of existing infrastructure to identify vulnerabilities and prioritize upgrades is also crucial. This proactive approach allows for targeted investments in retrofitting and strengthening buildings and critical infrastructure.

Question #4: Could you share some examples of successful projects that Wavin has undertaken in Malaysia, particularly those involving efficient and sustainable solutions like QuickStream?
