STOCKHOLM (Reuters) - Present plans by China and India for biofuel production could mean they face water scarcity by 2030, a researcher said.
Charlotte de Fraiture, a Colombo-based scientist with the International Water Management Institute (IWMI), said in an interview that she did not "see a lot of potential for biofuel production in either China or India because of the water.
"It's not that I'm saying don't go for biofuels. It's just that India and China are two water-short countries."
The IWMI carried out a five-year study on water which was completed in the spring of this year.
While water usage for biofuel crops is relatively small now, it is growing fast, as is the whole biofuel industry. Bioethanol production doubled between 1990 and 2003, de Fraiture wrote in a report, and is projected to double again by 2010.
About 7,130 cubic kms of water is used for food production, the IWMI says. One cubic kilometer is the volume of a cube with each side being one kilometer. It contains 1,000 trillion liters -- that's a 1 followed by 15 zeroes.
To put that in perspective, the runoff of the Nile river, for instance, is about 85 cubic kilolitres, de Fraiture says.
Right now, biofuel crops use about 100 cubic kilometers, or 1 percent of the total for food. Assuming biofuel usage rises as many expect, IWMI findings point to 180 cubic kilometers of water for irrigation being used for biofuel by 2030.
Both China and India are approaching water scarcity, which de Fraiture defines as using 75 percent of all potentially useable water for human purposes.
At 60 percent, a country is in the danger zone and both China and India are at that level.
"Those two countries, if they pursue their biofuel plans as they are on the table now, they will definitely be in the red zone in water terms," she said.
China and India could focus on improving their water management systems. "But that only brings them so far because water is a scarce good in those countries. Both of the countries are now into infrastructural solutions," she said.
An ambitious project to link rivers in India and a project to bring water from the water-rich south to the north are examples that show policy makers in both countries are aware of the problems they face, de Fraiture said. 第一次翻译，能给个机会么？24小时后若未提交译文，请其他战友自由认领。 呵呵，不用这么客气，欢迎认领
其实只要你在“回复话题”的时候按照一下统一确认认领语就行了，

斯德哥尔摩(路透社)——目前中国和印度的生物燃料生产计划可能意味着他们在2030年将面临缺水问题，一名研究员说。
Charlotte de Fraiture, a Colombo-based scientist with the International Water Management Institute (IWMI), said in an interview that she did not "see a lot of potential for biofuel production in either China or India because of the water.
Charlotte de Fraiture，国际水管理研究所设在科伦坡的科学家，在一次采访中说到，由于水的问题她不认为中国或印度在生物燃料生产上有太多的潜力。
"It's not that I'm saying don't go for biofuels. It's just that India and China are two water-short countries."
"我不是说不要去做生物燃料.而这仅仅是因为印度和中国都是两个缺水的国家" .
The IWMI carried out a five-year study on water which was completed in the spring of this year.
IWMI进行了为期5年关于水的研究,已经在今年春天完成了.
While water usage for biofuel crops is relatively small now, it is growing fast, as is the whole biofuel industry. Bioethanol production doubled between 1990 and 2003, de Fraiture wrote in a report, and is projected to double again by 2010.
虽然现在用于生物燃料作物的水相对还少,但其用量正像整个燃料产业在迅速发展. de Fraiture在一份报告中写道，乙醇产量在1990年至2003年翻了一番，预计到2010年将再翻一番.
About 7,130 cubic kms of water is used for food production, the IWMI says. One cubic kilometer is the volume of a cube with each side being one kilometer. It contains 1,000 trillion liters -- that's a 1 followed by 15 zeroes.
IWMI报道，约7,130公里立方的水用于粮食生产。一立方公里的体积每条边为一公里.它等于1000万亿升--1后面有15个零。
To put that in perspective, the runoff of the Nile river, for instance, is about 85 cubic kilolitres, de Fraiture says.
合乎比例地讲,例如,尼罗河的径流量是约85立方千升,de fraiture说.
Right now, biofuel crops use about 100 cubic kilometers, or 1 percent of the total for food. Assuming biofuel usage rises as many expect, IWMI findings point to 180 cubic kilometers of water for irrigation being used for biofuel by 2030.
