             This photograph was taken on March 4, 2006 by astronauts 
              aboard the International Space Station while flying over the Ca 
              Mau peninsula on the southern tip of Viet Nam. The provincial capital 
              Ca Mau is located in the centre of the picture. The low-lying terrain 
              is drained by a myriad of canals and natural drainage ways. The 
              intense agricultural land use relies on rich alluvial soil that 
              was deposited over many centuries and millennia by the Mekong River. 
              Many of the rice fields around the city can be identified by their 
              rich brown colour; they are in the process of being replanted and 
              irrigated for a new crop. The white and black dots on the photograph 
              are clouds and associated shadows.
