1. 世界気象機関(WMO)は、気候、環境、社会の変化が地球の水資源に及ぼす影響を評価した「世界の水資源の現状」報告書を初めて公表した。この報告書は毎年発行される予定である。

2. 現在、36億人が1年に1カ月以上、水へのアクセスが不十分な状態にあり、2050年には50億人以上に増加すると予測されている。

3. 報告書に掲載されたデータによると、2021年は世界的に見ても異常に乾燥した年であったことが示されている。例年より乾燥した状況に直面した地域は、雨の多い状況に直面した地域の2倍の広さであった。

State of Global Water Resources (WMO report)


The impacts of climate change are often felt through water – more intense and frequent droughts, more extreme flooding, more erratic seasonal rainfall and accelerated melting of glaciers – with cascading effects on economies, ecosystems and all aspects of our daily lives. And yet, there is insufficient understanding of changes in the distribution, quantity, and quality of freshwater resources. The State of Global Water Resources report aims to fill that knowledge gap and provide a concise overview of water availability in different parts of the world. This will inform climate adaptation and mitigation investments.

【Main Points】

1. The World Meteorological Organization (WMO) has published its first State of Global Water Resources report, which assesses the effects of climate, environmental and societal change on the Earth’s water resources. The report will be published annually.

2. Currently, 3.6 billion people face inadequate access to water at least one month per year and this is expected to increase to more than 5 billion by 2050.

3. Data presented in the report shows that at the global level 2021 was an unusually dry year. The area facing drier-than-usual conditions was twice as large as that experiencing wetter conditions.
