文 本 解 說

由于全球氣候的變化，巴拿馬運河經歷了過去七十年間第五嚴重的干旱年，這給經濟及生態的發展帶來了嚴峻的挑戰。為解決這一問題，有關各方正在采取包括限行船只在內的各項措施，而修建水庫及水道的提議也有望在年中左右得以通過。

The Panama Canal'swatershedexperienced its fifth driest year of the last seven decades in 2019, officials said,underscoringwarnings that climate change poses a major challenge to the recently expanded waterway, a major driver of the Central American nations' economy.

The annual report from the Canal Authority said that the watershed received 84.6 inches (2,149 millimeters) ofprecipitationlast year, about 20% below the historic average of 106.1 inches (2,695 millimeters).

Steven Paton ofthe Smithsonian Institution's Tropical Research Institutetoldthe Associated Pressthat since 2000, the watershed has seen the driest three-year stretch on record as well as eight of the ten biggest storms.

That reflects a trend toward more extreme weather events.

The canal underwent a multibillion-dollar expansion with the opening of new locks in 2016 to accommodate larger, New Panamax-class ships capable of carrying far more cargo than the biggest vessels that were previously able totransitthe waterway.

In early 2019 authoritiesimplementeddrafting restrictions for vessels due to low water levelsamida severe dry spell, forcing large ships to cross with less below capacity cargo loads and lowering revenues.

Water levels have fallen again during the current dry season at Gatun Lake, through which ships cross on the interoceanic voyage, though experts say it is too early to tell if drafting restrictions will again be necessary this year.

Canal authorities expect to finish various studies around midyear on proposals to build new reservoirs or channel water from other sources to the lakes.
