Climate change and water shortage have emerged as the top issues with the greatest impact on Asia, according to a survey of business leaders by the World Economic Forum. The survey, released at the close of the 17th World Economic Forum on East Asia, wrapped up a two-day meeting dominated by discussions on “the three Fs”, as Ahn Ho-Young, Deputy Minister for Trade of the Republic of Korea, put it – food, fuel and finance. He said these were not new uncertainties as the world has seen them in the past and he emphasised what he considered to be the more important issue of climate change.
