Increasingly volatile rainfall patterns speed up investments in infrastructure that distracts, stores and cleans rainwater, creating opportunities for suppliers of innovative hardware and advisory services, writes Senior Portfolio Manager Justin Winter.1
Extreme rainfall and more frequent flood events bear rising human and financial costs. In the five years until 2022, Economic losses due to global floods A total of $ 286 billion, an increase of 40% on the previous period of five years.
Rising incidence and value that risk due to flooding is expected to stimulate rising investments in rainwater infrastructure. We believe that this will support the demand for innovative products and services that help to better manage risks to ownership and life.
It is a hard rain of the A-Gonna
Atmospheric water levels reach new highlights: For every increase in temperature of 1 ° C, 7% more moisture Can be kept in the air. In addition to strengthening the cycle of global warming – water vapor works like a greenhouse gas – it increases the intensity of rainfall.
Extreme rainfall events that were expected earlier every 50 years earlier now occur every five years – and are being About 20% more intense. In Texas in July, four months of rain fell within a few hours, which led to Flash floods that killed at least 135 people and destroyed surrounding areas.
Uneven surfaces make urban areas particularly vulnerable to the worst effects. One study found that for every percentage point rise in the field of roads, sidewalks and parking spaces of US Cities, The annual flood size in nearby waterways is increasing by 3.3%.
The toll of catastrophic floods in Valencia in October 2024, that cost 0.2% of the Spanish GDP and more than 200 liveswas worse by fast urban expansion.
Adjust Urban Infrastructure
According to Global water informationThe existing urban water infrastructure is increasingly short of what is needed to cope with more intense rainfall events.
GWI estimates that the expenditure for municipal water infrastructure must rise six -time in 2040 to maintain water security in the midst of increasingly heavier weather. Of the $ 20 trillion in capital whose estimates it must be used in 2040, around $ 4 trillion would be needed for rainwater and flood management (see production 1).
‘Sponge City’ and advanced drainage
Cities must upgrade water infrastructure to adapt to a changing climate supports the demand for the services of technical consultancy firms that specialize in water management.
For example, Dutch Arcadis has worked on a project to develop a sustainable urban rainwater management system in Berlin. The ‘Sponge City Berlin’Project is intended to protect the city against the impact of floods with the help of, for example, green roofs, artificial water basins and semi-permeable pavements.
In addition to a greater use of nature -based solutions, cities and utilities must invest in physical equipment to distract and store surplus surface water to minimize damage and disruption. Hardware for rainwater management includes corrosion -resistant thermoplastic pipes, drainage structures and retention rooms.
Consequently, Advanced Drainage Systems offers systems that capture and treat rainwater that often contain heavy metals, oils and other pollutants as the outcome of roads and industrial locations, as well as agricultural land. Recording these prevents their return to water systems or the wider environment, so that infrastructure owners who do not take reasonable precautions that are exposed to fines.
As the chance of extreme rainfall increases, that will also be the costs of unpreparability. We believe that leading suppliers of the hardware needed to distract rainwater to distribute, to store and treat-EVENS Consultants who design system-wide solutions will play an essential role in adapting cities to a changing climate.

Investing in emerging markets or specialized or limited sectors is probably subject to higher than average volatility due to high concentration, greater uncertainty because less information is available, there is less liquidity or due to greater sensitivity to changes in market conditions (social, political and economic conditions). Some emerging markets offer less security than most international developed markets. For this reason, services for portfolio transactions, liquidation and retention can lead to a greater risk on behalf of funds invested in emerging markets.
