過去30年間で増大する洪水、干ばつなどの自然災害

 2012-03-08
イギリスの経済雑誌The Economistに興味深い記事が掲載されていました。

過去30年間に洪水や干ばつ、嵐が世界規模で急増しているという内容です。確かに、つい最近でもタイの洪水がありました。これらは異常気象の影響だと推察されますが、同様に経済的損失もばかにならないことが報道されています。

Quantifying the damage from floods, storms and droughts

THE number of severe floods, droughts and storms has increased worldwide over the past three decades, according to the OECD’s Environmental Outlook To 2050. Data from the Centre for Research on the Epidemiology of Disasters show that from 1980 to 2009 floods accounted for over 40% of what it terms weather-related disasters, storms nearly 45% and droughts 15%. Between 100 million and 200 million people a year were affected, and economic losses amounted to between $50 billion and $100 billion annually. The report suggests that by 2050 more than 1.6 billion people (or nearly 20% of the world's population) and assets worth $45 trillion could be at risk from the impact of increased flooding. The cities most likely to be affected are largely in Asia. They include Dhaka, Kolkata, Shanghai, Mumbai, Jakarta, Bangkok, and Ho Chi Minh City.
