BENGALURU, India — Climate change is hitting Asia hard, especially in terms of water and power systems. Two recent reports highlight how rising water-related disasters are putting millions at risk and pressuring governments to invest billions in basic services.
Water-related disasters are becoming more common. The Asian Development Bank (ADB) states that countries in Asia will need about $4 trillion for water and sanitation by 2040, which breaks down to almost $250 billion each year. Unfortunately, current government spending only covers 40% of this need, leaving a significant investment gap.
Asia’s water supply is under threat. While 2.7 billion people have reliable access to water, over 4 billion still rely on unsafe sources. ADB’s report highlights progress, especially in rural areas, but warns of a troubling trend: water ecosystems are rapidly declining due to pollution and unchecked development. A staggering 41% of global flooding occurs in Asia, affecting coastal cities and leading to severe challenges from rising sea levels and storm surges.
This year alone, Asia experienced devastating storms, like Typhoon Kalmaegi in Vietnam, which left countless homes submerged. Residents like Hai Duong found themselves desperately seeking power sources in malls to charge their phones amidst the chaos, illustrating the human impact of these disasters.
Experts like Vivek Raman from the ADB describe the situation as a “tale of two realities.” While there’s potential for improvement, the ongoing environmental pressures complicate efforts to provide clean water consistently.
In terms of energy, Asia suffers losses of approximately $6.3 billion each year due to extreme weather, with projections suggesting this could rise to $8.4 billion by 2050. Most of Asia’s power generation relies on coal, making it vulnerable. Anjali Viswamohanan, the director of policy at the Asia Investor Group on Climate Change, emphasizes that many companies are ill-prepared to handle these challenges. Research indicates that extreme heat is the leading cause of financial losses for power plants, notably in countries like India and Malaysia.
Declining river flows add another layer of risk, as many power plants depend on these water sources. Heavy rainfall poses additional threats, particularly for coastal facilities, like those operated by Tenaga Nasional in Malaysia, which are situated in low-lying areas vulnerable to flooding.
Despite these alarming trends, many utilities lack robust plans for climate adaptation. A recent study found that while some companies are aware of the risks, only a few have examined how these factors could impact their operations financially.
Jakob Steiner, a geoscientist, notes that addressing these financing gaps in the energy sector might be more feasible compared to the water and sanitation sector, given higher investor interest in energy projects. However, there’s a risk that seeking funding from less scrupulous sources could lead to compromises on environmental standards.
As climate change continues to push the boundaries of what’s possible, the need for immediate action in both the water and energy sectors is clear. With millions of lives at stake, the time for change is now.
