Evaluation of water demand and supply in the south of Iraq
This paper presents results from the first study that focuses on water resources availability and demand for different purposes in the four oil-rich provinces of southern Iraq. The region accounts for 23% of the surface area and 18% of the country's population, but holds 88% of its oil. A water shortage of 430 Mm3/year for 2010 is estimated for this region where irrigation accounts for 81% of ...

China: The South-North Water Transfer Project-is it justified?
The South–North Water Transfer Project (SNWTP), if fully developed, could divert 40–50 km3/yr from the Yangtse basin to the North China plain, alleviating water scarcity for 300–325M people living in what even then will be a highly water-stressed region. Construction of the next stage, diverting up to 20 km3 at a cost of about $17,000M (including $7000M in ancillary costs), is to start in ...

The Arkansas irrigation yield contest
Most farmers are familiar with contests in which participants try to achieve the maximum yield of a crop from a given field. Fewer would be familiar with a contest in which participants’ total crop yield is divided by the amount of water they use—thus measuring their water use efficiency. That’s the kind of contest that Dr. Chris Henry and his colleagues at the University of ...
