Malaysia Needs US$32b for Disaster Resilience!

 

Malaysia is projected to require US$32.56 billion (RM128.81 billion) in spending for disaster risk reduction and resilience measures. This is part of broader climate adaptation needs over the coming decades, according to the World Bank. These measures include strengthening land use planning, enforcing stricter building standards, investing in flood-resilient infrastructure, and restoring natural ecosystems that can better absorb and retain water.

 

In its Country Climate and Development Report (CCDR) for Malaysia, the World Bank said additional financing needs are even larger in other critical areas, with US$69.8 billion required for water supply infrastructure and US$33.5 billion for irrigation over the next 25 years.

Overall, total climate adaptation investment could reach between US$852 billion and US$1.13 trillion in nominal terms by 2050, encompassing the cost of upgrading infrastructure, strengthening disaster response systems, and protecting key economic sectors.

 

Flooding remains the most significant natural disaster in Malaysia, accounting for 85% of all disasters since 2000, with more than a third of towns and cities projected to face flash flood risks by 2100. Urbanisation has compounded these risks, with built-up areas expanding rapidly and reducing natural flood mitigation capacity, thereby increasing exposure to flash floods and landslides.

 

The report highlighted that over 5,496 flood hotspots have already been identified nationwide. Climate change is expected to increase flood risks across most river basins by about 15% by 2100.

 

Sea-level rise poses another major threat, particularly to coastal economic hubs such as Port Klang, Penang and Johor, with a one-metre rise potentially resulting in the loss of around 180,000ha of agricultural land and up to 20% of mangrove forests.

 

The agriculture sector is also at risk, with rising temperatures and erratic rainfall expected to reduce crop yields by up to 6% by 2050, affecting key commodities such as rice, rubber and palm oil.

The tourism sector could also decline significantly by the 2040s, with international tourism revenue projected to fall by between 12.2% and 21.3% due to rising temperatures and degraded natural attractions.

 

At the macro level, climate change could shave up to 8.3% off Malaysia’s GDP by 2050 in a worst-case scenario, driven largely by heat stress and flood-related disruptions. Heat stress alone is projected to reduce labour productivity, with agricultural output potentially declining by as much as 18% by mid-century while overall productivity losses could affect all sectors of the economy.

 

The report noted that climate risks are already materialising, with heavy rainfall between 2015 and 2024 estimated to have reduced firm revenues and productivity by about 3% on average, equivalent to around US$7 billion (RM27.68 billion) in GDP losses.

 

Smaller firms and startups are particularly vulnerable, experiencing declines up to eight times larger than bigger companies due to limited access to finance and weaker resilience capacity.

The report added that around 23% of Malaysia’s population is already exposed to climate shocks, with poorer households more likely to suffer long-term economic setbacks.

 

Despite the risks, the World Bank said proactive adaptation measures — including improved infrastructure, climate-resilient agriculture and stronger disaster management systems — could offset up to half of the projected economic losses.
