Taiwan’s thirst for rain grows stronger amid climate change

TAIPEI (TVBS News) — Once again, the water supply in southern Taiwan has hit an all-time low due to record-low rainfall in the area, the lowest in the past 30 years. 

In particular, the amount of rainfall collected in the Tsengwen Reservoir catchment area was 112 mm less than during the most severe drought of the century two years ago.

According to atmospheric scientist Dr. Peng Chi-ming, Taiwan is desperately waiting for the arrival of southwest monsoons, which could bring about more rain in May, particularly during the "Plum Rain season."
 
As Taiwan experiences increasingly severe droughts and longer dry periods, many wonder why reservoirs cannot retain water from concentrated rainfall during typhoon seasons. 

Currently, about one-third of reservoirs in Taiwan have a high accumulation of sediment, and experts predict this number could increase to half by 2030.

Furthermore, old pipes in reservoirs also contribute to leaks. Additionally, Taiwan's comparatively low water rates may result in less public motivation to conserve water. 
 
To address the water shortage issue, Peng suggests a comprehensive upgrade to Taiwan's water storage infrastructure and better allocation of water resources.

As climate change intensifies, Taiwan must find a more efficient way to retain rainfall and water before the next severe drought hits the island.
