MA is Mfg Plant Code (see http://www.harriger.com/exptire.htm), L9 is a tire size code, ABCD is optional manufacturer info, 036 is mfg date (in this case third week of unspecified year ending in 6, but not 2006) The newer tires are using 4 digits, the first 2 = the week, and the last 2 = the year. For example 4202 = 42nd week of 2002.
Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife.esertification often causes rural lands to become unable to support the same sized populations that previously lived there. This results in mass migrations out of rural areas and into urban areas, particularly in Africa.
