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.
The Sahel: a report on desertification. The Sahel is a semi-arid to arid area of scrubland and desert stretching primarily across the countries of Ethiopia, Eritrea, Djibouti, and Somalia, covering about 3,053,200 square kilometers. It is the transition between the Sahara desert and the wetter slightly tropical areas of Africa. Desertification in the Sahel is progressing at an alarmingly rapid rate, with 2,500 hectares, an area the size of Luxemburg, being desertified each year. Desertification is the process by which land is turned from semi-arid scrubland to desert. This is caused by a myriad of reasons, both human and environmental.
