Cool Geo-Pic: Border Result of Different Agricultural Use

Found the cool geo-pic from the familiar NASA Earth Observatory. Fascinating how the different demands & policies for agricultural land use can produce such a stark contrast.

Geo-Pic:
Where China and Kazakhstan Meet


Quick "Cut & Paste" Description:

"....The border between the two countries is defined by land-use policies. In China, land use is intense. Only 11.62 percent of China’s land is arable. Pressed by a need to produce food for 1.3 billion people, China farms just about any land that can be sustained for agriculture. Fields are dark green in contrast to the surrounding arid landscape, a sign that the agriculture is irrigated. As of 2006, about 65 percent of China’s fresh water was used for agriculture, irrigating 629,000 square kilometers (243,000 square miles) of farmland, an area slightly smaller than the state of Texas....."

".....The story is quite different in Kazakhstan. Here, large industrial-sized farms dominate, an artifact of Soviet-era agriculture. While agriculture is an important sector in the Kazakh economy, eastern Kazakhstan is a minor growing area. Only 0.03 percent of Kazakhstan’s land is devoted to permanent agriculture, with 20,660 square kilometers being irrigated....."
