By the year 2100, Singapore’s temperature is projected to rise by 1.4°C to 4.6°C and sea levels could rise by up to 1m*. The intensity and frequency of heavy rainfall events are also likely to increase while conversely, dry seasons could become even drier.
Building on the findings from BCA’s Coastal Adaptation Study, long term strategies will be developed to protect Singapore’s coasts. In the meantime, several measures have been implemented to protect our coastline. Some of these strategies include:

Heavy rainfall events could mean more frequent and intense floods in Singapore. To mitigate flood risks, PUB adopts the source-pathway-receptor approach so as to capture, redirect and keep excess water at bay. This includes:
Stamford Diversion Canal and Detention Tank
The Stamford Diversion Canal and Detention Tank enhances flood protection in the heart of the city at the Stamford Catchment, which includes the popular Orchard Road area. This is another great example of co-location with the Botanic Gardens coach bay sited above the tank!
The Urban Heat Island effect will compound warming caused by climate change.
Strategies to maintain thermal comfort include:

The impact of climate change is also expected to cause widespread declines in crop yields of up to 25% by 2050 globally. By importing over 90% of our food supply, Singapore is exposed to the volatilities of the global food market.
One key strategy being adopted to strengthen our food security is to boost our “grow local” basket, to reduce our reliance on food imports. Our aim is to build up our capability and capacity to produce 30% of Singapore’s nutritional needs locally by 2030.
In order to achieve this “30 by 30” target while optimising land, modern high-tech farms such as Sky Greens are increasingly adopting innovative technologies to intensify production.
