2013世界防治荒漠化和干旱日主题是什么
是2013年
答案
“The theme of the 2013 World Day to Combat Desertification is drought and water scarcity. Freshwater is valuable. Of all the water on Earth, only 2.5 per cent is freshwater. And of all this freshwater, the total usable supply for ecosystems and humans is less than 1 per cent. When demand for water exceeds available supply, it results in water scarcity. Drylands are particularly vulnerable to water scarcity. The projected intensification of freshwater scarcity will cause greater stresses in drylands. While each person needs at least 2,000 cubic meters of water for human well-being and sustainable development every year, on average, people in the drylands have access to only 1,300 cubic meters.”
“This year’s slogan, “Don’t let our future dry up” calls for everyone to take action to promote preparedness and resilience to water scarcity, desertification and drought. ”(source: UNCCD)
那么 2013年的主题就是干旱和水资源匮乏问题.
然后 今年的标语是“不要让人类的未来枯竭了”.
希望能帮到你.
