UNITED NATIONS Cheap Nike Air Max 1 Online , April 20 (Xinhua) -- A new tool offered by the Food and Agriculture Organization of the United Nations (FAO) uses real-time satellite data to track water productivity in agriculture, UN spokesman Stephane Dujarric told reporters here Thursday.
"The WaPOR open-access database has gone live online as of today, tapping satellite data to help farmers achieve more reliable agricultural yields and allowing for the optimization of irrigation systems," Dujarric said at a daily news briefing here.
"FAO's teams have designed WaPOR to cover Africa and the Near East, with a focus on key countries that are or are projected soon to face physical or infrastructural water scarcity Cheap Nike Air Max 97 Online ," said the spokesman.
Worldwide water utilization -- the majority of which is used by agriculture -- has outpaced the rate of population growth for most of the last century and some regions are close to breaching viable limits, he added.
WaPOR was presented this week during a high-level partners meeting for FAO's Coping with water scarcity in agriculture: a global framework for action in a changing climate.
It allows for fine-grained analysis of water utilised through farming systems, generating empirical evidence about how it can be most productively used.
"Water use continues to surge at the same time that climate change -- with increasing droughts and extreme weather -- is altering and reducing water availability for agriculture," says Maria Helena Semedo, FAO's deputy director-general for climate change and natural resources. "That puts a premium on making every drop count Cheap Nike Air Max 95 Online , underscoring the importance of meeting growing food production needs from efficiency gains."
WaPOR sifts through satellite data and uses Google Earth computing power to produce maps that show how much biomass and yield is produced per cubic meter of water consumed.
The maps can be rendered at resolutions of as little as 30 to 250 meters, and updated every one to ten days.
FAO's team of information technology and land and water officers has designed WaPOR -- through a 10-million-U.S. dollar project funded by the government of the Netherlands -- to cover Africa and the Near East, with a focus on key countries that are or are projected soon to face physical or infrastructural water scarcity.
Country level data will be made available in June for Benin, Burundi, Egypt Cheap Nike Air Max 90 Online , Ethiopia, Ghana, Jordan, Kenya, Lebanon Cheap Nike Air Max Online , Mali, Morocco, Mozambique, Rwanda, South Sudan Cheap Air Max 1 Online , Syria, Tunisia, Uganda, West Bank and Gaza Strip, and Yemen.
Even more detailed data will come online in October Cheap Air Max 97 Online , starting with pilot areas in Lebanon, Ethiopia and Mali.

BEIJING, July 14 (Xinhua) -- A Chinese Foreign Ministry spokesperson said on Friday that the one-China principle has become the general consensus of the international community.
It was reported that Taiwan's current leader Cheap Air Max 95 Online , Tsai Ing-wen, issued a "most heartfelt welcome" to visiting Paraguayan president Horacio Cartes. Tsai said on Twitter that Taiwan and Paraguay signed new economic cooperation agreements.

"Any attempt to create 'two Chinas' or 'one China, one Taiwan' will be firmly opposed by the Chinese people," Geng said Cheap Air Max 90 Online , adding that such an attempt is not in accordance with the fundamental interest of the people of Taiwan.
